When a transient exceeds 13.3 V (the minimum breakdown voltage), the device clamps to a maximum of 19.9 V while shunting up to 75.3 A of peak pulse current. The clamping voltage of 19.9 V is the peak voltage the downstream circuitry sees during a surge event. For a 12 V bus powering a sensor or communication module, a 20 V clamp leaves margin for 12 V-rated components with typical absolute maximum ratings of 30-36 V, provided the transient energy stays within the 1.5 kW rating. Housed in the DO-214AB (SMC) package, this is the standard footprint for 1.5 kW TVS diodes. The SMC package provides a larger copper pad area than the smaller SMA/SMB siblings, which helps conduct heat from the die to the PCB during repetitive surge events. Surface-mount assembly with Tape & Reel (TR) or Cut Tape (CT) options — the TR quantity suits production pick-and-place; CT works for prototype or low-volume builds. The operating temperature range spans -55°C to 150°C junction, covering industrial enclosures and underhood automotive locations where ambient temperatures can reach 125°C.","metaTitle":"SMCJ12A-13 TVS Diode, 1.5 kW, 12 V Standoff, DO-214AB","metaDescription":"SMCJ12A-13 Zener TVS diode by Diodes Inc.
