1500 W clamp for 36 V automotive buses
The SMCJ36CAQ-13-F: When the protected line exceeds the 40 V minimum breakdown threshold, the device clamps at a maximum 58.1 V while shunting 25.8 A of peak pulse current — this clamping voltage is the figure a downstream IC's absolute-max rating must clear. Qualified to AEC-Q101, the part is screened for automotive-grade reliability: the -55°C to +150°C junction temperature range covers under-hood and cabin deployments where thermal cycling and surge events are routine.
Package and board-fit
Housed in the DO-214AB (SMC) package, the device is surface-mount and occupies the standard SMC footprint. The bidirectional configuration means a single component protects both polarities on the same line — no need for two back-to-back unidirectional parts. Supplied on Tape & Reel (or Cut Tape), the part is ready for high-volume pick-and-place assembly. The base product number SMCJ36 identifies the family; the -13-F suffix denotes the reel packaging variant.
Sourcing and lifecycle posture
For a BOM hedge, a parametric search on 1500 W, 36 V standoff, bidirectional, DO-214AB yields functional equivalents from other manufacturers; the AEC-Q101 grade narrows the field to automotive-qualified parts.
