Product details

85V standoff TVS — DO-214AA, 600W peak pulse

Its 85V reverse standoff voltage means the protected line can carry 85V continuously without the diode conducting leakage current.

Clamping voltage and pulse current — the transient budget

Rated for 600W peak pulse power with a 10/1000µs waveform, the device can sink 4.4A peak pulse current before the clamping voltage reaches 137V. This defines the upper limit of the transient energy the diode can absorb — if the application's surge exceeds this, either a higher-power device or a multi-stage clamp is needed.

Package and temperature range — board-fit check

Frequently asked questions

Is SMBJ85AE3/TR13 a unidirectional TVS diode?

Yes — it has one unidirectional channel, meaning it clamps transients in one polarity (positive relative to ground). For bidirectional protection on an AC line or a bipolar signal, a different device with two back-to-back Zener junctions would be required.
