Product details

1500 W peak pulse — clamping voltage and breakdown threshold

The 1.5KE350CA A0G: Breakdown occurs between 333 V minimum and the clamping ceiling — the 300 V reverse standoff voltage is the continuous DC or peak AC line level the device blocks without conducting.

Bidirectional channel for AC or bipolar rail protection

A single bidirectional channel means the TVS clamps equally on positive and negative transients — suited for AC signal lines, bipolar power rails, or data lines where the signal swings through zero.

DO-201 axial through-hole — board integration and thermal path

Housed in a DO-201AA (DO-27) axial leaded package, the 1.5KE350CA A0G mounts through-hole — the copper leads conduct heat into the PCB pads, and the body withstands wave-solder profiles without moisture sensitivity level concerns typical of plastic SMD packages. Operating junction temperature range spans -55°C to 175°C, covering industrial cabinet ambient and under-hood automotive environments where the TVS sits near hot power resistors or transformers.

Frequently asked questions

What does the 482 V clamping voltage mean for my circuit?

At the rated 3.2 A peak pulse current (10/1000 µs waveform), the TVS limits the transient voltage to 482 V maximum. The protected rail must tolerate this peak without breakdown — if the downstream components have a lower absolute maximum rating, a lower-voltage TVS or additional clamping stage is needed.
