Description

The SMPA1302-079LF plastic-packaged, surface-mountable, low

capacitance (0.3 pF) silicon PIN diode is designed for switch and

attenuator applications used in vehicle infotainment.

The nominal 50 μm I region width, combined with a maximum

resistance of 3 Ω at 10 mA, makes these diodes useful in large

signal switch applications.

The low capacitance (< 0.30 pF) is ideal for high isolation

switching, and the long lifetime (700 ns) makes this part ideal for

low distortion attenuator applications.

Table 1 describes the SMPA1302-079LF package and marking.

1 Exposure to maximum rating conditions for extended periods may reduce device reliability. There is no damage to device with only one parameter set at the limit and all other parameters

set at or below their nominal value. Exceeding any of the limits listed here may result in permanent damage to the device.

ESD HANDLING: Although this device is designed to be as robust as possible, electrostatic discharge (ESD) can damage this device.

This device must be protected at all times from ESD when handling or transporting. Static charges may easily produce

potentials of several kilovolts on the human body or equipment, which can discharge without detection.

Industry-standard ESD handling precautions should be used at all times.
