1500 W peak pulse, 48 V rail — where it fits
The SMCJ48A-13-F: With a 48 V reverse standoff voltage (Vrwm), it clamps at 77.4 V max and handles a peak pulse current of 19.4 A — sized for 48 V DC power buses, telecom line cards, or industrial control rails where a single transient event can exceed the downstream regulator's abs-max. The 53.3 V minimum breakdown voltage (Vbr) means the device starts conducting just above the nominal rail, leaving headroom before the 48 V supply's normal tolerance band.
Housed in a DO-214AB (SMC) package, the SMCJ48A-13-F is a surface-mount device with a standard footprint shared across the SMCJ family. The SMC package body dissipates the 1500 W pulse through the copper pad area on the PCB — the thermal impedance is set by the board's copper pour, not the package itself. Supplied in Tape & Reel (TR) or Cut Tape (CT) options for both production reels and prototype pick quantities.
