5.0SMDJ43CA TVS Diode SMC

5.0SMDJ43CA is a bidirectional high-power surface-mount transient voltage suppressor from the 5.0SMDJ series. It delivers 5000W peak pulse power under standard 10/1000μs surge waveform. Equipped with SMC (DO-214AB) low-profile low-inductance package, this bidirectional TVS absorbs both positive and negative voltage surges induced by transmission lines. It provides comprehensive protection against ESD, lightning surges and switching transients for sensitive chips and electronic equipment, with ultra-low leakage and picosecond fast response to ensure stable circuit normal operation.

Description

5.0SMDJ43CA is a bidirectional high-power surface-mount transient voltage suppressor from the 5.0SMDJ series. It delivers 5000W peak pulse power under standard 10/1000μs surge waveform. Equipped with SMC (DO-214AB) low-profile low-inductance package, this bidirectional TVS absorbs both positive and negative voltage surges induced by transmission lines. It provides comprehensive protection against ESD, lightning surges and switching transients for sensitive chips and electronic equipment, with ultra-low leakage and picosecond fast response to ensure stable circuit normal operation.
