SMCJ28A-TR Description

Short technical summary and product information.

The SMCJ28A-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. The device features a reverse standoff voltage of 28V and a clamping voltage of 59V, ensuring that downstream components are not exposed to damaging overvoltage conditions.

 

With a peak pulse power rating of 1500W (1.5kW) and a peak pulse current of 169A under an 8/20µs waveform, this diode provides robust transient protection for general-purpose applications. The device is unidirectional with a single channel, making it suitable for DC power rail and signal line protection where polarity is fixed.

 

The SMCJ28A-TR is housed in a DO-214AB (SMC) surface mount package, which offers a compact footprint for automated assembly. It supports an operating temperature range of -55°C to 150°C, allowing reliable performance in harsh environments. The part is RoHS3 compliant and has an MSL rating of 1 (unlimited), simplifying handling and storage requirements.
