Ensure supply chain sources provide original manufacturer documentation to guarantee component authenticity and performance consistency.

Single Zener Diodes Selection Notes

Select this component when a 100 V Zener clamp is required in a compact SMA package. The 1 W power rating supports moderate surge handling. Verify that the system's operating temperature remains within the specified -55°C to +150°C range to maintain electrical characteristics and long-term reliability.

Single Zener Diodes Part Context

This part belongs to Comchip Technology's ACZRA series of ruggedized Zener diodes. The series utilizes flat-chip manufacturing techniques to ensure robustness against mechanical stress and thermal cycling. These components are engineered for high-reliability environments where standard discrete semiconductors may fail under harsh conditions.

Single Zener Diodes Replacement Considerations

Cross-reference with other 100 V, 1 W Zener diodes in the DO-214AC package from different manufacturers. Ensure equivalent impedance and leakage current specifications match the original design requirements before substitution.
