The operating junction temperature range spans -65°C to 150°C, covering the underhood hot-soak condition where a 125°C-rated part would be at its absolute limit. The 150°C TJ rating provides margin for self-heating during repetitive surge events in engine-bay or transmission-control environments. ## 1500W pulse power — what the 10/1000 µs rating actually means At the clamping voltage of 18.2V, the device conducts 82.4A of peak pulse current — enough to shunt a 1500W transient from a 24V truck battery line without exceeding the junction's SOA. The reverse standoff voltage of 11.1V means the diode stays in high-impedance mode on a nominal 12V automotive rail, only beginning to conduct when the transient exceeds 12.4V (minimum breakdown). This leaves the protected circuit operating at 12V nominal without leakage current from the TVS. ## Single bidirectional channel — one part protects both polarities A single bidirectional channel means this TVS clamps positive and negative transients symmetrically. On a signal line subject to both positive and negative surges — such as a CAN bus differential pair, a sensor output, or an RS-485 line — one DO-214AB package replaces two unidirectional TVS diodes in anti-series, saving board area and BOM count. The part does not include power line protection features — the 'No' flag on power line protection confirms this is intended for signal or data-line clamping, not for bulk DC rail protection where a higher-standoff, higher-energy TVS would be specified. ## Surface-mount DO-214AB — the SMC footprint The DO-214AB (SMC) package is a standard JEDEC footprint with a 0.260-inch body width. The cathode band marking identifies orientation for the bidirectional device, though polarity is symmetrical for this part. The SMC package handles the 1500W pulse without requiring through-hole mounting — important for automated assembly lines running reflow profiles.","metaTitle":"Vishay 1.5SMC13CAHM3/I TVS, 1500W, 11.1V, AEC-Q101, DO-214AB","metaDescription":"Vishay 1.5SMC13CAHM3/I bidirectional TVS diode, 1500W peak pulse, 11.1V reverse standoff, AEC-Q101 qualified.
