Active, 600W, 150V — BOM-fit snapshot
The SMBJ150CA-13-F: The breakdown voltage range starts at 167 V min, giving you the margin to protect a 150 V rail from transients without nuisance triggering.
What the clamping numbers mean on your board
The 243 V clamping ceiling is the voltage the diode forces across the protected line during a surge — downstream components must survive that peak. With a 150 V standoff, the diode stays transparent during normal operation; leakage is negligible until the transient exceeds 167 V breakdown. Single bidirectional channel means one device clamps both polarities, saving a diode and a PCB via compared to back-to-back unidirectional parts. Useful on AC signal lines or bipolar DC rails where the transient can swing either way. The DO-214AA (SMB) surface-mount package keeps the assembly compatible with standard reflow profiles.
Sourcing and compliance
Supplied in Tape & Reel (TR) or Cut Tape (CT) options, which suits both prototype runs and high-volume pick-and-place. General-purpose application classification means it is not qualified to AEC-Q101, but the temperature range and power rating cover many non-automotive harsh-environment designs. RoHS and REACH compliance documentation is available from Diodes on request.
