The SMCJ20A-TR is a unidirectional transient voltage suppression (TVS) diode manufactured by STMicroelectronics. It is designed to protect sensitive electronic circuits from voltage transients induced by lightning, inductive load switching, and electrostatic discharge.
Key electrical specifications include a reverse standoff voltage of 20V, a maximum clamping voltage of 42.8V at the peak pulse current, and a peak pulse power rating of 1500W (1.5kW). The device can handle a peak pulse current of 234A under an 8/20µs waveform. It is not intended for power line protection and is classified for general purpose applications.
The SMCJ20A-TR is housed in a surface-mount DO-214AB (SMC) package, making it suitable for automated assembly processes. It operates over a junction temperature range of -55°C to 150°C.
