Clamp voltage and transient protection fit
The 1.5KE27CA R0G: At the 42 A peak pulse current (10/1000 µs waveform), the clamp voltage reaches 37.5 V max — this is the voltage the downstream device must survive. The 1500 W peak pulse rating is the product of that clamp voltage and current, giving the energy-handling capacity for a single transient event.
Package, temperature range, and mounting
Housed in a DO-201AA / DO-27 axial-lead package (supplier device package DO-201), the part is through-hole mounted — the lead bend and hole diameter in the PCB layout must match the DO-201 footprint for proper solder-joint reliability over temperature cycling. The wide range means the TVS maintains its breakdown voltage spec across cold-start and hot-soak conditions without derating the clamp performance.
Sourcing and compliance posture
Listed as Active in production by Taiwan Semiconductor Corporation, the 1.5KE27CA R0G is available through authorized and independent distribution channels. Sourced per RFQ — no stock-holding claim; lot traceability and date-code consistency are confirmed at quote time.
