TVS clamping and the 15 V rail it protects
The SMAJ15A-13-F: Its 15 V reverse standoff voltage (VRWM) means it sits across a 15 V DC rail without conducting leakage current under normal operation.
Package, temperature grade, and board-fit
The SMA footprint is widely used for 400 W class TVS diodes, making the part a drop-in replacement candidate for other SMAJ-series devices with the same voltage rating. The part is available in Tape & Reel (TR) or Cut Tape (CT) packaging, suiting both high-volume pick-and-place and prototype or low-quantity builds.
