TVS diode for 130V automotive rails
The 1.5KE160HE3/54: It provides 1500W peak pulse power (1.5kW) at 10/1000µs waveform, clamping transients on 130V nominal rails to 230V maximum. The 6.5A peak pulse current rating at the 10/1000µs pulse defines the energy it can absorb in a single event.
Package and temperature rating
Housed in a DO-201AA (DO-27) axial-lead through-hole package, the 1.5KE160HE3/54 mounts into a standard 0.100-inch pitch hole pattern. The operating junction temperature range spans -55°C to 175°C, covering under-hood and engine-bay thermal profiles where ambient temps can exceed 125°C. It is intended for production automotive ECUs and modules where reliability traceability matters.
Vishay has marked the 1.5KE160HE3/54 as obsolete. No official successor order code is recorded in the lifecycle data. The base product number 1.5KE160 covers a family of TVS diodes in the same package and voltage class. Buyers maintaining a 130V rail protection position should verify the specific breakdown and clamping requirements against the remaining active 1.5KE160 variants if a design refresh is planned.
