1500 W peak pulse in a DO-201AE axial package
The 1.5KE160A_R2_00001: Housed in the DO-201AE axial-lead package, it mounts through hole on a PCB — the leaded form factor suits point-to-point wiring or board-level transient suppression where surface-mount reflow is not preferred. The operating junction temperature range spans -65 °C to 175 °C, covering military and industrial thermal extremes.
Obsolete — sourcing through independent channels
Panjit has marked the 1.5KE160A_R2_00001 as obsolete. No official successor or second-source order code is recorded. The 1.5KE series is a mature TVS diode family, and the DO-201AE package remains a common footprint. A functionally equivalent replacement from another manufacturer would require matching the 136 V standoff, 152 V breakdown, and 219 V clamp at the same 1500 W peak pulse rating — a parametric search against those values is the practical migration path.
Clamping voltage and transient energy handling
At the rated 6.8 A peak pulse current (10/1000 µs waveform), the clamping voltage is 219 V maximum. This means a transient on a 136 V nominal rail is clamped to 219 V before the diode conducts the surge current to ground — the downstream circuitry must survive that peak voltage for the pulse duration. The 1500 W peak pulse rating is the product of the clamping voltage and the peak current at that condition. For shorter pulses (e.g., 8/20 µs), the peak current capability is higher; for longer pulses, derating applies. The 10/1000 µs waveform is the industry-standard benchmark for TVS diodes and correlates to typical lightning-induced or inductive-load transients.
