The SMCJ6V5CA is a surface-mount Transient Voltage Suppressor (TVS) diode manufactured by Fairchild Semiconductor, which is now part of ON Semiconductor. This TVS diode is designed to protect sensitive electronic components from voltage transients induced by various sources, including lightning, electrostatic discharge (ESD), and inductive load switching. This specific part is a bidirectional TVS diode, meaning it provides overvoltage protection in both directions.

Additional Details

The SMCJ6V5CA has a standoff voltage of 6.5V and a breakdown voltage around 7.22V. The clamping voltage is designed to keep the voltage across the protected component at a safe level during a transient event. It is packaged in an SMC (DO-214AB) package, suitable for surface mounting on printed circuit boards. The operating temperature range is typically from -65°C to +150°C.
