Product details

7.5V rail clamp in a DO-214AC footprint

The SMAJ7.5E3/TR13 is a unidirectional Zener TVS diode from Microchip, designed to clamp transients on a 7.5V nominal rail (reverse standoff voltage,). Breakdown occurs at 8.33V minimum, and the clamping voltage is held to 14.3V at the peak pulse current of 35A. That 14.3V ceiling is what matters for downstream IC survival — the rail sees no more than that during the surge event.

The wide Tj range also means derating at elevated temperatures is less aggressive than with commercial-grade parts.

Listed as Active, the SMAJ7.5E3/TR13 is in ongoing production at Microchip.

Frequently asked questions

Where can I buy SMAJ7.5E3/TR13?

SMAJ7.5E3/TR13 is an active Microchip part. We source it through franchised and authorized distribution channels. Submit an RFQ with your target quantity and lead-time requirement; we confirm availability and current pricing at quote time.

Is SMAJ7.5E3/TR13 unidirectional or bidirectional?

It is a unidirectional device — one channel. The cathode band on the DO-214AC package marks the ground side; the anode connects to the protected rail.

Can SMAJ7.5E3/TR13 replace SMAJ7.5A?

The base product number is SMAJ7.5. The '' suffix indicates Microchip's lead-free / RoHS-compliant finish. The 'A' suffix on other variants typically denotes a different tolerance on breakdown voltage. Check the specific datasheet for the SMAJ7.5A to confirm electrical equivalence — the package and footprint are the same DO-214AC.
