What are the key features of 1.5KE100CA?
- 1500 W peak pulse power (10/1000 µs) with bidirectional clamping at 100 V nominal breakdown for AC and bipolar circuit protection
- Tight 95 V to 105 V breakdown voltage tolerance enabling precise overvoltage protection on 85 V to 100 V rails
- UL-recognized DO-201 axial package with matte tin lead finish and 175°C maximum junction temperature for high-reliability industrial use
What is 1.5KE100CA used for?
The 1.5KE100CA is used to protect 85 V to 100 V AC and DC circuits from transient overvoltage events such as lightning surges, electrostatic discharge, and inductive load switching spikes. Its bidirectional characteristic and 1500 W peak pulse power make it suitable for industrial motor drive inputs, AC power line protection modules, and telecommunications equipment operating at high voltage rails. It is also applied in railway and heavy industrial systems where both polarities of transient must be suppressed.

Frequently Asked Questions
What peak pulse power and clamping voltage does the 1.5KE100CA provide during a transient event?
The 1.5KE100CA dissipates 1500 W peak pulse power under a 10/1000 µs waveform and clamps to a maximum of 178 V during a transient at its rated test current. For shorter 8/20 µs surges (such as lightning impulse waveforms), the device can handle up to 10 kW peak. The nominal breakdown voltage is 100 V, with a tolerance band from 95 V to 105 V, making it appropriate for 85 V to 100 V rail protection.
Why choose a bidirectional 1.5KE100CA over the unidirectional 1.5KE100A for AC line protection?
The 1.5KE100CA is bidirectional, meaning it suppresses transients of both polarities symmetrically, which is essential on AC signal lines or power inputs where the waveform swings positive and negative. The unidirectional 1.5KE100A only clamps in the forward direction and would conduct like a forward-biased diode during negative half-cycles, potentially shorting the protected line. For 100 V AC mains or bipolar industrial bus lines, the 1.5KE100CA is the correct choice.
How does the 1.5KE100CA capacitance affect high-frequency circuit designs?
The 1.5KE100CA has a minimum diode capacitance of 575 pF, which is typical for high-power TVS diodes in the DO-201 package. At signal frequencies above a few hundred kilohertz, this capacitance can introduce significant reactive loading and attenuate signal edges. For high-speed data lines or RF circuits, low-capacitance TVS arrays with capacitance below 10 pF per channel should be used instead; the 1.5KE100CA is best suited for power line and low-frequency signal protection up to 100 V.
Can the 1.5KE100CA operate in high-temperature environments such as industrial motor drives?
Yes, the 1.5KE100CA supports a maximum junction temperature (Tj max) of 175°C, which is above the typical 150°C limit of standard TVS diodes and makes it suitable for high-temperature industrial environments including motor drive control boards and power conversion equipment. At Tj max, the device retains up to 1100 W peak pulse power dissipation capability under a 10/1000 µs waveform, ensuring robust protection even under thermally stressed operating conditions.
