1500W bidirectional TVS for 33V automotive rails
The SMCJ33CAQ-13-F is a 1500W peak pulse power bidirectional Zener TVS diode from Diodes Incorporated, housed in a DO-214AB (SMC) package. It is qualified to AEC-Q101, the automotive-grade semiconductor reliability standard covering temperature cycling, ESD sensitivity, and PPAP documentation. With a 33V reverse standoff voltage and a 53.3V maximum clamping at 28.1A peak pulse current (10/1000µs waveform), this part protects 33V nominal rails — common in automotive battery, ECU, and sensor supply lines — from load-dump and transient overvoltages.
AEC-Q101 qualification and operating envelope
The 36.7V minimum breakdown voltage ensures the device begins clamping before the protected rail exceeds its absolute maximum rating, while the 53.3V clamp voltage limits the voltage spike seen by downstream components.
Active lifecycle and sourcing posture
Available through independent distribution channels; pricing and lead time are confirmed at RFQ against the buyer's quantity.
