Device identity and key parametrics
The Vishay 1.5KE110CAHE3_A/D is a bidirectional TransZorb TVS diode from the Automotive series, qualified to AEC-Q101, in a DO-201AA (DO-27) axial-lead through-hole package. The single bidirectional channel handles a peak pulse current of 9.9 A under the 10/1000 µs condition, making it suitable for protecting 94 V nominal rails from load-dump and surge events.
Automotive grade and temperature envelope
The operating junction temperature range spans -55°C to 175°C, covering under-hood and engine-bay thermal profiles without derating concerns at the upper end. Marked for automotive applications, it suits 24 V and 48 V vehicle electrical systems where the 94 V standoff provides margin above the nominal bus voltage.
