Product details

1500W TransZorb TVS for 138V rails

The 1.5KE170CHE3/73 is a 1500W peak pulse power TransZorb Zener TVS diode from Vishay, designed to clamp transients on 138V nominal DC rails.

Clamping and pulse current profile

At the 6.1A peak pulse current (10/1000µs waveform), the clamping voltage reaches 244V maximum. This is the voltage the protected circuit must survive — a 138V bus sees a transient clamped to 244V, which is within the typical 250V-300V MOSFET breakdown range for 150V-rated DC-DC converters.
