Key Features
- Bidirectional 75 V TVS diode with 83.3 V to 92.1 V breakdown range and 121 V max clamping voltage, providing reliable overvoltage protection for AC and DC lines
- DO-214AB (SMC) package with silicon diode construction supporting high peak pulse power dissipation for robust ESD and transient surge suppression
- Single-element silicon TVS rated for repetitive transient clamping, suitable for industrial and automotive line protection applications requiring long service life
Applications
The SMCJ75CA is used to protect power supply rails, communication interfaces, and industrial I/O lines operating near 75 V from ESD, lightning surge, and inductive switching transients. Its bidirectional configuration makes it ideal for AC signal lines and bridge rectifier inputs where both positive and negative transients must be clamped below 121 V. The compact SMC (DO-214AB) surface mount package allows direct placement near vulnerable circuit nodes on high-density PCBs.

Frequently Asked Questions
What breakdown voltage range and clamping voltage does the SMCJ75CA provide during a transient surge?
The SMCJ75CA has a breakdown voltage range of 83.3 V minimum to 92.1 V maximum, with a nominal value of 87.7 V. During a surge event, it clamps the voltage to a maximum of 121 V, protecting downstream components on 75 V rated circuits from damaging overvoltage conditions.
Can the SMCJ75CA protect both AC signal lines and DC power rails from ESD transients?
Yes, the SMCJ75CA is a bidirectional TVS diode, enabling it to clamp both positive and negative transients on AC signal lines and DC power rails up to 75 V standoff voltage. Its silicon construction and DO-214AB SMC package support repetitive ESD clamping events without degradation in typical industrial environments.
How does the SMCJ75CA compare to unidirectional TVS diodes for protecting DC bus lines near 75 V?
Compared to unidirectional TVS diodes, the SMCJ75CA provides bidirectional clamping suitable for AC-coupled or reverse-polarity protection scenarios on 75 V DC bus lines. Unidirectional devices clamp only one polarity and can fail if reverse transients appear, while the SMCJ75CA's 83.3 V to 92.1 V bidirectional breakdown range ensures full surge suppression regardless of transient polarity.
