Product details

Unidirectional 85V TVS in a DO-214AB SMC package

Its 1500W peak pulse power rating handles surge events like inductive load dumps or lightning-induced spikes in general-purpose industrial and telecom equipment.

Clamping voltage and breakdown margin for 85V rails

The maximum clamping voltage at the 9.9A peak pulse current is 151V — this is the voltage the protected circuit must survive without damage. The 1500W peak pulse power is the headline surge rating.

Active lifecycle and ordering for production

The suffix indicates a lead-free, RoHS-compliant finish; no separate Pb-free qualification step is needed for this variant.

Frequently asked questions

Does the SMCJ85E3/TR13 have a bidirectional equivalent?

The SMCJ85E3/TR13 is unidirectional (single TVS die with one cathode band). For bidirectional clamping on an 85V AC line or a bipolar rail, look for the SMCJ85CA (bidirectional) variant in the same DO-214AB package — it uses two back-to-back Zener dies in a single package. The unidirectional and bidirectional versions are not pin-compatible for the same PCB footprint without a layout change.

What does the suffix mean on Microchip TVS diodes like SMCJ85E3/TR13?

The suffix on Microchip TVS diodes indicates a lead-free, RoHS-compliant finish. It does not change the electrical specifications — the breakdown voltage, clamping voltage, and peak pulse power are identical to the non- variant. The TR13 suffix denotes Tape & Reel packaging.
