13V rail clamp — 400 W peak pulse in a DO-214AC footprint
The SMAJ13A-13-F: Its 14.4 V minimum breakdown and 21.5 V maximum clamping at 18.6 A peak pulse (10/1000 µs waveform) define the protection envelope for that rail voltage. Single unidirectional channel — this part is polarity-sensitive and intended for DC bus protection, not AC or bidirectional signal lines.
Package and board-fit — DO-214AC (SMA)
Housed in the industry-standard DO-214AC (SMA) surface-mount package, the SMAJ13A-13-F reflows with standard Pb-free profiles. The SMA footprint is shared across the entire SMAJ family, making it a drop-in for existing layouts using this power class. Supplied on Tape & Reel (TR) or Cut Tape (CT) — the TR option is the standard reel quantity for pick-and-place; CT suits prototype or low-volume builds.
Temperature range and application scope
Rated for continuous operation from -55°C to +150°C junction temperature — this spans industrial control cabinets, outdoor telecom enclosures, and under-hood automotive modules where the ambient sees 85–105°C. For designs requiring automotive-grade or a specific immunity standard, the buyer should verify the device meets their transient test level.
Pricing and stock are confirmed at quote time against the BOM quantity. The part is available in both reel and cut-tape formats; lot traceability and date-code freshness are verified per RFQ.
