It clamps transients on a nominal 18.8 V DC rail — the reverse standoff voltage — to a maximum of 30.6 V when hit with a 49 A peak pulse current (10/1000 µs waveform). Housed in a DO-201AA (DO-27) axial-leaded package, it mounts through-hole — the leads are formed for insertion into a 1.0 mm diameter PCB hole. The body is 9.1 mm long, so plan for lead-bending clearance on the board edge. The junction temperature rating sets the derating curve for sustained high-power pulses. The AEC-Q101 qualification and TransZorb® construction mean any replacement should match the 1500 W peak pulse, 18.8 V standoff, and bidirectional clamping profile.","metaTitle":"Vishay 1.5KE22CAHE3/51 TVS Diode, 1500W, Bidirectional","metaDescription":"Obsolete Vishay 1.5KE22CAHE3/51 bidirectional TVS diode, 1500W peak pulse, 18.8V standoff, AEC-Q101.
