The document describes the SigICT-10 series, specifically models ICT-5 through ICT-45C, which are Transient Absorption Zener (TAZ) devices. These components are engineered to protect bipolar, MOS, and Schottky integrated circuits against transient voltage spikes across various logic families including CMOS, TTL, ECL, OTL, RTL, and linear functions.
The datasheet provides maximum ratings such as a peak pulse power dissipation of 1500 Watts at 25°C and operating temperatures ranging from -65°C to +175°C. It includes detailed electrical characteristics tables for both unidirectional (suffix C) and bidirectional types, listing parameters like stand-off voltage, reverse breakdown voltage, clamping voltage, and peak pulse current.
| Peak Pulse Power Dissipation | 1500 Watts at 25°C |
|---|---|
| Operating Temperature Range | -65° to +175°C |
| Forward Surge Rating | 200 amps, 1/120 second at 25°C |
| Steady State Power Dissipation | 1.0 watt |
| Clamping Factor (Full Rated) | 1.33 |
They are designed to protect bipolar, MOS and Schottky improved integrated circuits.
The clamping factor is 1.33 when measured at full rated power.
Bidirectional models are indicated by a 'C' suffix on the part number.
