Product details

Protection window and pulse capability

The 1.5KE33C-E3/54: The 26.8 V reverse standoff voltage means the device does not conduct at normal rail voltage up to that level, and breakdown begins at 29.7 V minimum. A single bidirectional channel handles symmetrical clamping in both polarities, eliminating the need for back-to-back series diodes in AC or bipolar DC lines.

Temperature range and package

Housed in a DO-201AA (DO-27) axial leaded package for through-hole mounting on boards or terminal strips where surface-mount TVS would risk solder joint fatigue under vibration.

Lifecycle and procurement

Sourced to order against an RFQ; availability and date-code provenance confirmed at quote time.
