SMCJ30 Description

Short technical summary and product information.

The Bourns SMCJ30 is a unidirectional Transient Voltage Suppressor (TVS) diode designed for general purpose applications. This component offers a reverse standoff voltage of 300V and a breakdown voltage of 335V minimum. It can handle a peak pulse current of 3.1A and a peak pulse power of 1500W (1.5kW) for a 10/1000 µs waveform.

 

The SMCJ30 operates within a temperature range of -55°C to 150°C (TJ). It is housed in a surface-mount DO-214AB (SMC) package, making it suitable for various PCB designs. The component is rated at Moisture Sensitivity Level 1 (Unlimited) and is RoHS3 compliant.

 

This TVS diode is ideal for protecting sensitive electronic components from transient voltage events. Its robust construction and specified electrical characteristics make it a reliable choice for power line protection and other surge suppression needs.
