Product details

TVS clamp for a 64V rail — breakdown and clamping limits

Its minimum breakdown voltage is 71.1V, providing a 7.1V guard band above the standoff — enough headroom to avoid nuisance clamping during normal rail ripple while still triggering before the downstream components see damaging voltage. When the transient hits, the diode clamps at a maximum of 114V while conducting a peak pulse current of 5.3A (10/1000µs waveform).

DO-214AA SMB — surface-mount for automated assembly

Housed in the DO-214AA (SMB) package, this TVS is a surface-mount device supplied on tape and reel.

Frequently asked questions

Is SMBJ64E3/TR13 unidirectional or bidirectional?

It is a unidirectional Zener TVS — one channel, cathode band on the package. For a bidirectional clamp on the same rail, you would need two devices back-to-back or a dedicated bidirectional part such as the SMBJ64CA.
