500W bidirectional Zener TVS in a through-hole axial package
It clamps transients at 151.3V max with a reverse standoff of 86.6V, making it suitable for protecting 86V DC rails or signal lines from surges up to 3.3A peak pulse current. The single bidirectional channel means one device protects both positive and negative overvoltage events on a line, saving board space compared to two unidirectional diodes back-to-back.
Minimum breakdown voltage is 104.5V, so the diode begins conducting at that threshold. The clamping voltage at peak pulse current is 151.3V — the maximum voltage the protected circuit sees during a surge. For a 86.6V nominal rail, this leaves a 17.9V margin above the standoff before clamping, which is typical for a Zener-based TVS. The wide range means the breakdown voltage shifts less than 10% across temperature, but derate the peak pulse power above 25°C per the datasheet curve.
Active production – sourcing through distribution
The through-hole B Axial package is a leaded form factor compatible with wave soldering and hand rework. No moisture sensitivity level (MSL) concern — axial diodes are not moisture-sensitive.
