Additional Details

The SA15AHE3/54 has a standoff voltage of 15V. It's crucial to select a TVS diode with a standoff voltage slightly above the normal operating voltage of the protected circuit to prevent interference during normal operation. The clamping voltage indicates the maximum voltage that the TVS diode will allow to pass through during a surge. The peak pulse current rating indicates the maximum surge current that the TVS diode can handle safely. The device typically operates within a temperature range of -65°C to +175°C. It's constructed with a glass passivated junction for improved reliability and performance and features solderable terminals.
