SMCJ33A-TR ST Transient Voltage Suppressors (TVS)

The SMCJ33A-TR is a 1500W unidirectional Transil TVS diode from STMicroelectronics in SMC (JEDEC DO-214AB) surface-mount package, featuring 33V reverse standoff voltage for transient overvoltage protection. For selection, verify peak pulse power of 1500W for 10/1000µs waveform and 10kW for 8/20µs, low leakage current of 0.2µA at 25°C (1µA at 85°C), breakdown voltage range, clamping voltage at peak pulse current, planar technology for high reliability, fast response time, and operating junction temperature up to 150°C. Features include compliance with IEC 61000-4-2 Level 4 (15kV air/8kV contact discharge), IEC 61000-4-5, MIL STD 883G Method 3015-7 Class 3B (25kV HBM), and UL recognized. Ideal for voltage spike protection in 33V power systems, industrial power supplies, communication equipment, I/O interfaces, general purpose circuit protection, and any 33V nominal circuit requiring 1500W unidirectional transient suppression.
