1.5KE75HE3/54 — obsolete AEC-Q101 TVS, 1.5 kW peak pulse
The operating junction temperature range spans -55°C to 175°C, covering under-hood and powertrain thermal profiles. The DO-201AA (DO-27) axial-lead package suits through-hole mounting on automotive ECU boards or power-distribution PCBs.

Key parametric decisions for the BOM
The 60.7 V reverse standoff voltage (working voltage) means the diode does not conduct at normal rail levels up to that point. The 1500 W peak pulse rating at 10/1000 µs defines the energy-handling capability for a standard lightning or inductive-load transient. The 13.9 A peak pulse current is the corresponding current through the device at the clamping voltage. AEC-Q101 qualification means the part passed automotive-grade reliability tests (temperature cycling, high-temperature reverse bias, ESD) and is suitable for safety-related and mission-critical automotive circuits.
