Additional Details

The SMA5J16CHE3/61 features a standoff voltage of 16 V. Selecting the appropriate standoff voltage, slightly higher than the normal operating voltage, is crucial to avoid impacting regular circuit function. The clamping voltage indicates the maximum voltage allowed to pass through during a surge event. The peak pulse current rating defines the TVS diode's capacity to handle surge current safely. It generally operates within a temperature range of -65°C to +150°C. The device is manufactured using glass passivated chip junction technology, which contributes to its reliability and performance. It incorporates solderable matte tin-plated leads.
