What this Zener does in the circuit
The 1N6072A/TR: It clamps transients up to 328V at 4.6A peak pulse current, making it a fit for general-purpose surge protection on DC rails or signal lines where a single bidirectional device replaces two back-to-back Zeners.
Breakdown, clamping, and thermal range
Breakdown voltage is specified at 209V minimum — that is the threshold where the device starts conducting in avalanche. The clamping voltage caps at 328V maximum under the 4.6A peak pulse current, which defines the voltage the protected circuit must survive.
Active production and sourcing posture
It is supplied in Tape & Reel (TR) packaging for the DO-13 through-hole case. Sourced to order against your BOM quantity.
Package and mounting note
DO-13 (also referred to as DO-13) is a through-hole metal can package with two leads. The cathode band marks the polarity — on a bidirectional device orientation still matters for the PCB footprint, though the clamping is symmetrical. The 0.5 A continuous current rating is not listed, but the peak pulse current of 4.6A at 10/1000µs gives the surge capability; for continuous DC bias stay well below the 185V standoff.
