It protects a 40V nominal rail, with a breakdown voltage range starting at 44.4V and clamping at 71.4V maximum under the peak pulse current of 21A. This single bidirectional channel device handles surge events in general-purpose applications such as power supplies, telecom equipment, and industrial controls. ## Clamping voltage and surge current The 71.4V maximum clamping voltage at 21A peak pulse current defines the voltage the protected circuitry must survive. For a 40V rail, this leaves a 31.4V margin above nominal — typical for TVS diodes in this power class. The 1500W rating is measured with a 10/1000µs waveform; shorter pulses allow higher peak current before the device reaches its thermal limit. The device does not include power line protection features — it is a standalone transient suppressor for signal or DC power rails. The base product number SMCJ40 covers a family of voltage variants; this specific 'C' suffix indicates bidirectional polarity, and '' denotes lead-free / RoHS-compliant construction.","metaTitle":"SMCJ40CE3/TR13 Microchip 1500W Zener TVS Diode DO-214AB","metaDescription":"SMCJ40CE3/TR13 Zener TVS diode, 40V standoff, 1500W peak pulse, DO-214AB SMC.
