The 1.5KE91A-E3/54 is a 1500W unidirectional transient voltage suppressor (TVS) diode from Vishay Dale, designed to protect sensitive electronics from voltage transients. It is based on a Zener structure with a glass passivated chip junction for reliability.
Key electrical specifications include a reverse standoff voltage of 77.8V, a maximum clamping voltage of 125V at a peak pulse current of 12A (10/1000 μs waveform), and a peak pulse power rating of 1500W. The device also handles a peak forward surge current of 200A (8.3 ms half sine-wave). Operating temperature range is -55°C to 175°C.
The diode is housed in a through-hole DO-201AA, DO-27, or Axial package with matte tin-plated leads. Mounting is through-hole with axial lead style. The device is RoHS3 compliant (E3 suffix) and meets UL 94 V-0 flammability rating for the molding compound.
Typical applications include protection against inductive load switching and lightning-induced transients in consumer, computer, industrial, automotive, and telecommunication systems. The device offers fast response time and low incremental surge resistance.
