Obsolete — sourcing through independent channels
Panjit International Inc. lists the 1.5KE47CA_R2_00001 as Obsolete — the manufacturer no longer produces this part.
The clamping voltage of 64.8V at 23.2A peak pulse current defines the maximum voltage the downstream circuitry sees during the surge. Reverse standoff voltage is 40.2V, meaning the diode draws negligible leakage at normal operating voltages up to that level. Breakdown occurs at 44.7V minimum, so a 40V rail is protected without clipping the supply. Bidirectional — a single device clamps transients of either polarity, reducing component count on signal or power lines that see both positive and negative surges.
Package and deployment context
DO-201AE axial-lead through-hole package — the leads are inserted into plated through-holes on the PCB and soldered on the opposite side. This package is common in telecom, industrial, and power-supply boards where wave-solder assembly is standard. Operating temperature range spans -65°C to 175°C, covering outdoor enclosures, engine bays, and high-ambient industrial cabinets without derating.
