Product details

What this TVS does in the circuit

It clamps a surge to 9.6V maximum at a peak pulse current of 52A (10/1000 µs waveform), which keeps downstream 5V logic or power ICs inside their absolute-max ratings.

Voltage guardband and trigger threshold

The reverse standoff voltage is 5V, meaning the diode does not conduct at normal 5V rail levels. Breakdown starts at a minimum of 6.4V, and clamping hits 9.6V at full surge current — a tight window that avoids nuisance triggering from supply ripple while still protecting the rail.

Package and temperature range for field use

The junction temperature range is -65°C to 150°C, which covers most industrial and outdoor telecom environments without a derating headache. Lifecycle status is Active — no end-of-life notice or last-time buy pressure.

Sourcing and compliance posture

Frequently asked questions

How can I order SMAJ5.0CE3/TR13 or check stock?

SMAJ5.0CE3/TR13 is an active Microchip part. Submit an RFQ with your target quantity; we source through our distributor network and confirm availability and pricing per order. No stock-holding claim is made here.

What is the closest pin-compatible alternative to SMAJ5.0CE3/TR13?

The base product number is SMAJ5.0, so any SMAJ5.0 variant with the same package (DO-214AC) and bidirectional polarity is a direct footprint match. The SMAJ5.0A is the unidirectional version — same breakdown and clamp voltages but one-direction only. Confirm polarity before swapping.

Can SMAJ5.0CE3/TR13 replace SMAJ5.0A?

Not directly: SMAJ5.0CE3/TR13 is bidirectional, while SMAJ5.0A is unidirectional. On a 5V rail that sees only positive transients, the unidirectional part works; if transients can be negative, use the bidirectional version. The clamp voltage and breakdown specs are the same.
