Product details

What this TVS does on a 64 V rail

It is a single bidirectional channel, meaning it clamps both positive and negative spikes without needing two diodes back-to-back — useful on AC-coupled or bipolar supply lines where polarity is not fixed. The 71.1 V minimum breakdown voltage ensures the diode starts conducting before the downstream circuitry sees damaging overvoltage.

The operating junction temperature range spans -65°C to 150°C, covering industrial and some automotive under-hood environments where the ambient may reach 125°C. No power line protection is claimed — this is a general-purpose transient clamp, not a dedicated AC mains protector.

Microchip lists the SMAJ64CAE3/TR13 as Active.

Frequently asked questions

Is SMAJ64CAE3/TR13 obsolete?

No — Microchip lists it as Active. No EOL or PCN has been issued. It remains a current-production part suitable for new designs and ongoing production.

Is SMAJ64CAE3/TR13 bidirectional?

Yes. The part has a single bidirectional channel, clamping both positive and negative transients. This is confirmed by the 'CA' suffix in the base product number SMAJ64, which Microchip uses for bidirectional devices.

What is the peak pulse power of SMAJ64CAE3/TR13?

500 W peak pulse power measured with a 10/1000 µs waveform. The peak pulse current at that waveform is 4.9 A, and the maximum clamping voltage at that current is 103 V.

What package is SMAJ64CAE3/TR13 in?

DO-214AC (SMA) surface-mount package, supplied on Tape & Reel. The supplier device package is also listed as DO-214AC (SMA).
