500 W Zener TVS – 15.2 V Breakdown Floor
The 1N6111AE3/TR is a bidirectional Zener transient-voltage-suppression diode from Microchip Technology, rated for 500 W peak pulse power under the 10/1000 µs waveform. The minimum breakdown voltage is 15.2 V, with a typical reverse standoff of 12.2 V and a maximum clamping voltage of 22.3 V at the rated peak pulse current of 22.4 A. This is a general-purpose protection device in a through-hole B, Axial package, suited for clamping transients on DC power rails or signal lines where a bidirectional clamp is needed and the rail voltage sits below 12.2 V.
Junction Temperature Range and Pulse Capability
The 22.4 A peak pulse current is specified at the 10/1000 µs waveform — the standard telecom surge shape. For shorter pulses the device can handle higher peak current; for longer pulses the energy must be derated per the datasheet curve.
Active Production – Sourcing Through Distribution
Microchip lists the 1N6111AE3/TR as Active.
