SMCJ28A Description

Short technical summary and product information.

The Bourns SMCJ28A is a unidirectional TVS diode designed to protect sensitive electronic circuits from voltage transients. It offers a peak pulse power dissipation of 1500W (1.5kW) under a 10/1000µs waveform, making it suitable for high-energy transient suppression.

 

Key electrical specifications: The device has a reverse standoff voltage of 28V, ensuring minimal leakage under normal operation. The maximum clamping voltage is 45.4V at a peak pulse current of 33.1A. It is a general-purpose component, not intended for power line protection.

 

The SMCJ28A is housed in a DO-214AB (SMC) surface mount package, compatible with automated assembly processes. It operates over a temperature range of -55°C to 150°C. The package is designed for optimized board space and offers built-in strain relief.
