Product details

Transient suppressor for 1500 W surge environments

This part is designed for general-purpose transient protection on DC power rails and signal lines where a single bidirectional device replaces two unidirectional diodes in series.

Clamping voltage and surge current limits

The 245.7 V clamping maximum at 6.1 A peak pulse current defines the voltage the protected circuit sees during a surge. The 136.8 V standoff rating means the diode does not conduct at normal operating voltages up to that level, so it sits across the rail without leakage penalty. The 1500 W peak pulse power rating is the energy-handling ceiling for a single 10/1000 µs pulse — derate for repetitive events or higher ambient temperatures.

Active production, through-hole axial package

The part ships in the B, Axial package — a through-hole form factor suited for point-to-point wiring, terminal blocks, or PCB mounting where the axial leads are bent and soldered.

Frequently asked questions

Is 1N6172A equivalent to 1N6172?

The base product number 1N6172 shares the same mechanical and electrical family, but the 'A' suffix typically indicates a tighter tolerance on breakdown voltage. Confirm the breakdown voltage range for the non-A variant from its datasheet before substituting.

Can 1N6172A be used as a TVS diode for 1500W applications?

Yes. The 1N6172A is a Zener TVS diode rated for 1500 W peak pulse power at 10/1000 µs, making it suitable for transient suppression on 136.8 V nominal rails. The bidirectional configuration protects against both positive and negative surges without polarity concerns.
