Peak pulse ceiling: 1.5 kW at 10/1000 µs
The 1N6276A-E3/54: The 1N6276A-/54 is a unidirectional Zener-based transient voltage suppressor (TVS), Vishay's TransZorb® series in the 1.5KE family — a mid-range axial TVS package used across industrial control, power supply, and communication equipment protection rails. The peak pulse current is 66.7 A, which is the current the clamping action forces during a worst-case transient event.
The clamping window — what 13.6 / 15.2 / 22.5 V mean
The reverse standoff voltage is 13.6 V typical — this is the voltage present across the TVS during normal operation, so the rail it protects must sit below this level to avoid leakage conduction. Breakdown minimum is 15.2 V, meaning the TVS remains off below that threshold and transitions to conduction sharply once exceeded.
DO-201AA axial, full industrial temperature range
The DO-201AA (DO-27) through-hole package accepts standard axial lead assembly — the cathode band marks the anode-cathode orientation, which matters on a unidirectional device since reverse-bias is the protection polarity. Junction temperature rating spans -55 to 175 °C, which is the full industrial band and means this part suits environments where thermal cycling and transient heating are expected. The operating temperature limit is specified at the junction, not the lead — thermal resistance to the ambient determines whether the lead temperature actually stays within that window in the end equipment.
