Product details

60V rail protection in a standard SMA footprint

The SMAJ60A-13: That clamping voltage is the ceiling the downstream circuitry must survive — a 100V-rated capacitor or 100V MOSFET on the protected rail has margin here.

Package and thermal reach

Housed in a DO-214AC (SMA) surface-mount package, the SMAJ60A-13 reflows on a standard footprint shared with many SMA-packaged diodes. The junction temperature range spans -55°C to 150°C, covering both cold-start industrial environments and hot enclosures near power stages. No power line protection feature is built in — this is a pure transient suppressor, not a filter.

Frequently asked questions

Is the SMAJ60A-13 suitable for protecting a 60V DC bus?

Yes. The reverse standoff voltage is 60V, meaning the diode does not conduct at normal bus voltage. Breakdown begins at 66.7V minimum, providing a guard band before clamping at 96.8V.
