Product details

What this Zener TVS does on a 48V rail

Its reverse standoff voltage is 48V, with a minimum breakdown of 53.3V and a maximum clamping voltage of 77.4V at 6.5A peak pulse current.

Sourcing through franchised or independent channels

Because this is an active Microchip part with wide distribution, the spot market typically sees modest premiums unless a broader TVS shortage tightens supply. For BOM quantities, we source against your RFQ through franchised lines and vetted independent inventory — no stock-holding claim, confirmed at quote time.

Frequently asked questions

What is the closest pin-compatible alternative to SMAJ48AE3/TR13?

Within the SMAJ series, the base product number SMAJ48 covers multiple suffix variants (e.g., different screening levels or packaging). The DO-214AC footprint is standard across the series, so any SMAJ48 variant in the same package is a drop-in replacement. Confirm the specific breakdown and clamping specs match your design.
