They offer resettable protection against multi-Watt fault events without the need for multi-Watt heat sinks. The Zener diode used for voltage clamping in a PolyZen micro-assembly was selected due to its relatively flat voltage vs current response. This helps improve output voltage clamping, even when input voltage is high and diode currents are large. An advanced feature of the PolyZen micro-assembly is that the Zener diode is thermally coupled to a resistively nonlinear, polymer PTC (positive temperature coefficient) layer. This PTC layer is fully integrated into the device, and is electrically in series between VIN and the diode clamped VOUT. This advanced PTC layer responds to either extended diode heating or overcurrent events by transitioning from a low to high resistance state, also known as "tripping". A tripped PTC will limit current and generate voltage drop. It helps to protect both the Zener diode and the follow on electronics and effectively increases the diode's power handling capability. The polymer enhanced Zener diode helps protect sensitive portable electronics from damage caused by inductive voltage spikes, voltage transients, incorrect power supplies and reverse bias. These devices are particularly suitable for portable electronics and other low-power DC devices. BENEFITS * Stable Zener diode helps shield downstream electronics from overvoltage and reverse bias * Trip events shut out overvoltage and reverse bias sources * Analog nature of trip events minimizes upstream inductive spikes * Minimal power dissipation requirements * Single component placement FEATURES * Overvoltage transient suppression * Stable VZ vs fault current * Time delayed, overvoltage trip * Time delayed, reverse bias trip * Multi-Watt power handling capability * Integrated device construction * RoHS Compliant TARGET APPLICATIONS * DC power port protection in portable electronics * DC power port protection for systems using barrel jacks for power input * Internal overvoltage & transient suppression * DC output voltage regulation TYPICAL APPLICATION BLOCK DIAGRAM Power Supply PolyZen Protected Electronics (External or Internal) SUPERSEDED 2 VIN + 1 PolyZen Device GND VOUT NOT the LATEST REVISION 3 Regulated Output RLoad Protected downstream electronics PRODUCT: ZEN056V130A24LS PolyZen 308 Constitution Drive Menlo Park, CA 94025-1164 Phone: 800-227-4856 www.circuitprotection.com Polymer Enhanced Zener Diode Micro-Assemblies DOCUMENT: SCD 26730 REV LETTER: E REV DATE: OCTOBER 27, 2008 PAGE NO.: 2 OF 8 Raychem Circuit Protection Products CONFIGURATION INFORMATION Pin Configuration (Top View) 2 VIN Recommended Pad Dimensions 0.94 mm (0.037") GND 2.21 mm (0.087") 1 3 0.33 mm (0.013") 0.94 mm (0.037") VOUT 0.56 mm (0.022") 2.88 mm (0.1135") 0.56 mm (0.022") PIN DESCRIPTION Pin Number 1 2 3 Pin Name VIN GND VOUT Pin Function VIN.

Note 2: This device is intended for limited fault protection. Repeated trip events or extended trip endurance can degrade the device and may affect performance to specifications. Performance impact will depend on multiple factors including, but not limited to, voltage, trip current, trip duration, trip cycles, and circuit design. For details or ratings specific to your application contact Tyco Electronics Circuit Protection directly. Note 3: Specifications developed using 1.0 ounce 0.045" wide copper traces on dedicated FR4 test boards. Performance in your application may vary. Note 4: Izt is the current at which Vz is measured (VZ = VOUT). Additional VZ values are available on request. Note 5: IHOLD : Maximum steady state IPTC (current entering or exiting the VIN pin of the device) that will not generate a trip event at the specified temperature. Specification assumes IFLT (current flowing through the Zener diode) is sufficiently low so as to prevent the diode from acting as a heat source. Testing is conducted with an "open" Zener. Note 6: R Typ: Resistance between VIN and VOUT pins during normal operation at room temperature. st Note 7: R1Max: The maximum resistance between VIN and VOUT pins at room temperature, one hour after 1 trip or after reflow soldering. Note 8: VINT Max: VINT Max relates to the voltage across the PPTC portion of the PolyZen device (VIN-VOUT). VINT Max is defined as the voltage (VIN-VOUT) at which typical qualification devices (98% devices, 95% confidence) survived at least 100 trip cycles and 24hours trip endurance at the specified voltage (VIN-VOUT) and current (IPTC). VINT Max testing is conducted using a "shorted" load (VOUT = 0V). VINT Max is a survivability rating, not a performance rating. Note 9: IFLT Max: IFLT Max relates to the stead state current flowing through the diode portion of the PolyZen device in a fault condition, prior to a trip event. IFLT Max is defined as the current at which typical qualification devices (12 parts per lot from 3 lots) survived 100 test cycles. RMS fault currents above IFLT Max may permanently damage the diode portion of the PolyZen device. Testing is conducted with NO load connected to VOUT, such that IOUT = 0. "Test voltage" is defined as the voltage between VIN to GND and includes the PolyZen Diode drop. Specification is dependent on the direction of current flow through the diode. IFLT Max is a survivability rating, not a performance rating. Note 10: The power dissipated by the device when in the "tripped" state, as measured on TE test boards (see note 3). Note 11: Specifications based on limited qualification data and subject to change.
