Protection window and clamping performance
Bidirectional Zener TVS with 17.1 V reverse standoff voltage and 19 V minimum breakdown. Clamps at 27.7 V maximum at 54 A peak pulse current (10/1000 µs waveform). The 54 A Ipp figure is the current the diode shunts at the clamping voltage — the energy absorbed per pulse is the product of clamp voltage and pulse current over the waveform duration. Operating junction temperature range -65°C to 175°C. The wide cold end suits outdoor or unheated equipment; the 175°C max allows operation near power components or in confined enclosures.
DO-201AE axial package — board integration
Through-hole DO-201AE axial package. The body diameter and lead spacing match the standard DO-201 footprint; the axial leads are bent for through-hole insertion and wave solder. Supplied in Tape & Reel (TR) or Cut Tape (CT). The reel quantity follows the standard DO-201AE carrier tape format; CT available for prototype or low-volume builds.
