This document describes the features and characteristics of the P5KE series transient voltage suppressors, including unidirectional and bidirectional functionality, low inductance, and high temperature soldering.
The P5KE series from Micro Commercial Components are unidirectional and bidirectional transient voltage suppressors covering breakdown voltages from 5.0 V to 170 V. They are designed for low inductance, high‑temp soldering (250 °C for 10 s), and can be identified by adding a “C” suffix for bidirectional versions.
Key specifications include a 500 W peak pulse power capability, operating temperature range of –55 °C to +150 °C, and fast response times (1 µs for unidirectional, 5 µs for bidirectional). Detailed tables list breakdown voltage, reverse leakage, capacitance, and derating curves across the full voltage range.
| Peak Pulse Power | 500 Watt |
|---|---|
| Operating Temperature Range | -55°C to +150°C |
| Response Time (Unidirectional) | 1×10⁻⁶ seconds |
| Response Time (Bidirectional) | 5×10⁻⁶ seconds |
| Breakdown Voltage (P5KE5.0) | 5.0 V |
The devices operate from –55 °C up to +150 °C.
Each TVS diode can handle a peak pulse power of 500 W.
Unidirectional devices respond in about 1 µs (1×10⁻⁶ seconds).
