What the 24V standoff and 38.9V clamp mean for your rail
The SMAJ24CA-13: The 24V reverse standoff voltage means the device draws negligible leakage current on a 24V nominal rail, while the 26.7V minimum breakdown voltage guarantees avalanche conduction starts before the protected circuitry sees damaging overvoltage. The 38.9V maximum clamping voltage at 10.3A peak pulse current defines the worst-case voltage the downstream components must survive during a transient event.
Package, footprint, and temperature grade
Housed in the standard DO-214AC (SMA) surface-mount package, with the supplier device package designated as SMA. The DO-214AC footprint is shared across the SMAJ series, so a board already laid out for a 400W SMA TVS accepts this part without layout changes.
Obsolete — sourcing reality for the SMAJ24CA-13
Availability, lot traceability, and pricing are confirmed at the time of RFQ. The date-code and marking consistency should be verified against Diodes' factory format — the laser etch on the body is a fingerprint that distinguishes genuine stock from re-marked material.
