Its 18.8V reverse standoff voltage means the protected line can run at 18.8V nominal without the diode conducting leakage current; the breakdown minimum of 20.9V is where clamping begins, and the maximum clamping voltage of 30.6V at the 49A peak pulse current (10/1000µs waveform) defines the voltage the downstream circuitry must survive. The single unidirectional channel handles positive transients relative to ground; for bidirectional protection on AC or bipolar lines, two devices or a bidirectional variant would be needed. ## Package and board integration Housed in the DO-201AE axial-lead through-hole package, the diode is intended for hand-insertion or wave-solder assembly. The axial leads allow it to be mounted standing upright or laid flat against the board; the body diameter and lead spacing match the standard DO-201AE footprint used across the 1.5KE family. Operating temperature spans -65°C to 175°C junction, covering military and industrial thermal profiles. Power line protection is not implemented — the device is a standalone transient suppressor, not a filtered or coordinated protection IC. ## Sourcing reality for an obsolete part Panjit lists the 1.5KE22A_R2_00001 as obsolete. No official successor order code is recorded. For BOM lines that require this exact clamping voltage and package, supply is through independent distribution channels — quantities are confirmed at RFQ, and parts are sourced on a per-order basis. No pin-compatible drop-in replacement is documented from Panjit; a parametric search for a 1500W, 18.8V standoff TVS in DO-201AE from other manufacturers is the usual next step for new designs.","metaTitle":"Panjit 1.5KE22A_R2_00001 TVS Diode, 1500W, DO-201AE","metaDescription":"Panjit 1.5KE22A_R2_00001 Zener TVS diode, 1500W peak pulse power, 18.8V standoff, DO-201AE axial.
