Vishay 1-Element Bi-Directional TVS Diode, 1.5 kW, 2-Pin Through Hole, TRANSZORB TVS Series 1.5KE47CA-E3/54

Vishay 1.5KE47CA-E3/54 is a premium 1-Element Bi-Directional Transient Voltage Suppressor (TVS) diode designed to protect sensitive electronic components from voltage surges, spikes, and transient events. This TVS diode provides a peak pulse power dissipation rating of 1.5 kW, making it suitable for industrial, automotive, and electronic semiconductor protection applications.

The device uses a single diode configuration in a bi-directional direction type, enabling symmetrical voltage transient suppression in both polarities. It features a minimum breakdown voltage (Vbr) of 44.7 volts and a maximum reverse stand-off voltage (Vwm) of 40.2 volts, ideal for protecting circuits operating around these voltage levels.

Its package type is axial through-hole with a compact footprint - 9.5 mm in length and 5.3 mm in diameter, allowing easy PCB insertion. The diode withstands operating temperatures from -55°C up to 175°C, ensuring reliable performance in harsh environments such as automotive systems and rugged industrial electronics.

The 1.5KE47CA-E3/54 TVS diode complies with the automotive AEC-Q101 standard, offering reliable Electrostatic Discharge (ESD) protection, with a maximum peak pulse current (Ippm) of 23.1 amperes. Its clamping voltage of 64.8 volts effectively limits transient voltages, preventing damage to protected circuits.
