Microsemi Corp. the diode experts ; SCOTTSDALE, AZ / For more information call: / (602) 941-6300 FEATURES ECONOMICAL 1500 WATTS PEAK PULSE POWER DISSIPATION STAND OFF VOLTAGES FROM 5.5V - I71V e UNIPOLAR OR BIPOLAR AVAILABLE IN CHIP FORM FOR HYBRID APPLICATION MULTI-CHIP BIDIRECTIONAL CELLS AVAILABLE DESCRIPTION This defines a series of silicon Transient Suppressors designed to protect. voltage sensitive components from high energy voltage transients. TAZ devices have become very important as a consequence of their high surge capability, extremely fast response time, and low incremental surge resistance (Rs). To characterize TAZ, a minimum voltage at low current conditions (Vpp),anda maximum clamping voltage (Vc), at a maximum peak pulse current are speci- fied. In addition, a maximum clamping ratio is indicated. The maximum leak- age current at the rated stand-off voltage is also provided to assure low power consumption under normal conditions. APPLICATION This TAZ series has a peak pulse power rating of 1500 watts for one millisecond. It can protect integrated circuits, hybrids, CMOS, MOS, and other voltage sen- sitive components in a broad range of applications such as telecommunica- tions, power supplies, computers, automotive, and industrial equipment. MAXIMUM RATINGS 1500 Watts of Peak Pulse Power Dissipation at 25C. telamping (0 Volts to Very Min.): Unidirectional < 1x10" Seconds; Bidirectional <5 x 1079 Seconds. Operating and Storage Temperature -65C to +175C. Forward Surge Rating 200 Amps, 1/20 Second at 25C. Steady State Power Dissipation 5.0 W @ TI = 75C. (Not Applicable in Chip Form). ELECTRICAL CHARACTERISTICS Clamping Factor: 1.33 @ full rated power 1.20 @ 50% rated power The Clamping Factor is defined as: The ratio of the actual Vc (Clamping Voltage) to the actual Ver) Breakdown Voltage) as measured on a specific device. 1N6267 thru ING303A and 1.5KE6.8 thru 1.5KE400A TRANSIENT ABSORPTION ZENER UNIDIRECTIONAL AND BIDIRECTIONAL 190/.205 1.10 = ~ MIN, .B26/5.207 27.9 _/360/.975_ "" 9.144/9.525 ~ u a OMIN. 040 + 002 27.9 1.016 + .0508 All dimensions in_INCH MECHANICAL CHARACTERISTICS CASE: Molded WEIGHT: 15 Grams (Approx.)
