Its 13.6V reverse standoff voltage sits above the nominal battery rail, while the 15.2V minimum breakdown and 22.5V maximum clamping at 66.7A peak pulse current define the protection envelope for downstream electronics. The -55°C to 175°C operating junction range covers the full automotive thermal profile, including hot-soak near the exhaust tunnel. With a 22.5V maximum clamping voltage at 66.7A peak pulse current (10/1000µs waveform), this diode limits transients to a level that 30V-rated downstream MOSFETs and ICs can survive. The unidirectional configuration (single channel) clamps only positive transients above breakdown; for AC or bidirectional lines, two devices back-to-back or a dedicated bidirectional TVS is needed. Power line protection is marked as 'No', meaning this is a transient suppressor, not a continuous overvoltage clamp. ## Through-hole DO-201AA axial package — board integration The DO-201AA (DO-27) axial leaded package is a through-hole form factor suited for point-to-point wiring, terminal blocks, or PCB mounting with 0.040-inch diameter leads. The body dimensions and lead spacing are standard for 1.5 kW TVS diodes, allowing direct replacement with other 1.5KE-series parts without layout changes. Tape & Box (TB) packaging is specified — this is a bulk ammo-pack format for axial components, not reel. The base product number is 1.5KE16, and the full suffix includes the AEC-Q101 automotive designation (HE3). ## Active production — sourcing posture For non-automotive applications, the commercial 1.5KE16A (without HE3 suffix) is a functional equivalent, though AEC-Q101 qualification is absent.","metaTitle":"Vishay 1.5KE16AHE3_A/D TVS Diode, 1500W, AEC-Q101, DO-201AA","metaDescription":"Vishay 1.5KE16AHE3_A/D TransZorb TVS, 1500W peak pulse, 13.6V standoff, 22.5V clamp, AEC-Q101 qualified.
