Product details

Device identity and application fit

It is rated for general-purpose surge protection across -65°C to 150°C.

Key parametric ratings for BOM fit

The minimum breakdown voltage is 56.7V, ensuring the device does not conduct during normal operation. The clamping voltage is specified at 91.1V maximum at a peak pulse current of 18.5A (10/1000 µs waveform). That clamping ceiling defines the voltage stress the protected circuitry must survive during a surge event. Peak pulse power is rated at 1500W — a standard rating for this package size, giving a known energy-handling budget for transient suppression in a single unidirectional channel.

Production is ongoing, and the part is available for order against BOM quantities.

Frequently asked questions

Is SMCJ51E3/TR13 bidirectional?

No — it is a single unidirectional channel (one anode, one cathode). For bidirectional protection, two devices in anti-series or a dedicated bidirectional TVS would be needed.
