Product details

58V Zener TVS — 500W surge clamp for 48V rails

The 64.4V minimum breakdown voltage ensures the device starts conducting before the 103V clamping ceiling, protecting downstream components from overvoltage. The 4.9A peak pulse current rating provides headroom for moderate surge events.

DO-214AC SMA footprint and temperature range

Surface-mount DO-214AC (SMA) package — the same footprint used across the SMAJ family — simplifies PCB layout and reflow assembly.

Microchip lists the SMAJ58CE3/TR13 as Active. This part is available through our sourcing channel — confirm lead time and pricing with an RFQ against your BOM quantity.

Frequently asked questions

Is SMAJ58CE3 bidirectional?

Yes. It has 1 bidirectional channel, meaning it clamps transients of either polarity — suitable for AC or bipolar DC lines.

What is the peak pulse power of SMAJ58CE3?

500W peak pulse power measured with a 10/1000µs waveform. This defines the surge energy the device can absorb without failure.

Is SMAJ58CE3 RoHS compliant?

The evidence does not explicitly state RoHS compliance. Verify with the manufacturer's datasheet or our sales team at quote time.

What is the difference between SMAJ58CE3 and SMAJ58A?

The SMAJ58A is typically a unidirectional TVS, while the SMAJ58CE3 is bidirectional. Both share the DO-214AC package and similar voltage ratings, but the CE3 variant clamps both polarities without a separate diode bridge.
