1.5 kW bidirectional transient suppressor — 185 V standoff, 328 V clamp
The 1.5KE220CA_R2_00001: It clamps transients at 328 V maximum when the peak pulse current reaches 4.6 A, protecting downstream circuitry from surges up to that energy level. The bidirectional channel handles both positive and negative polarity surges, making it suitable for AC power rails or bipolar signal lines.
Package and thermal envelope
Housed in a DO-201AE axial-lead package, the 1.5KE220CA_R2_00001 mounts through hole — the leaded body provides a low-inductance path for fast transients and allows manual or wave-solder assembly. The junction temperature range spans -65 °C to 175 °C, covering industrial and some military-grade thermal profiles without derating at the high end. No power line protection feature is built in — this is a dedicated transient suppressor, not a crowbar or overvoltage clamp for continuous faults.
Obsolete — sourcing through independent channels
No official successor order code is recorded from Panjit. The 1.5KE series includes other bidirectional TVS devices at different voltage ratings, but a direct pin-compatible replacement at the same 185 V standoff is not documented. Buyers should verify the clamping voltage and peak pulse current requirements before selecting an alternative.
