Vishay 1-Element Uni-Directional TVS Diode 1.5 kW 2-Pin Through Hole Package 1.5KE 1.5KE170A-E3/54

Vishay 1.5KE170A-E3/54 is a 1-Element Uni-Directional Transient Voltage Suppressor (TVS) diode designed for protecting sensitive electronics from voltage transient spikes. This TVS diode supports a peak pulse power dissipation of 1.5 kW, making it suitable for high-energy transient suppression in electronic circuits.

Featuring a minimum breakdown voltage of 162 V and clamping voltage of 234 V, the device ensures efficient shunting of transient voltage spikes while maintaining normal operational stability at a maximum reverse stand-off voltage of 145 V. It operates reliably over a broad temperature range from -55°C to 175°C, suitable for harsh industrial, automotive, and commercial electronics environments.

The diode comes in a compact 2-pin through-hole axial package measuring 5.3 mm in diameter, 9.5 mm in length, and 5.3 mm in height, enabling ease of integration onto printed circuit boards (PCBs). It also complies with the AEC-Q101 automotive standard guaranteeing quality and robustness for automotive applications. The device includes inherent electrostatic discharge (ESD) protection and maintains a minimal maximum reverse leakage current of 1 μA, maximizing energy efficiency and protecting downstream circuitry.

This single element uni-directional TVS diode is ideal for transient voltage suppression in power supplies, industrial machines, automotive systems, telecommunications equipment, and HVAC controls. It effectively safeguards sensitive components from voltage surges caused by lightning, inductive load switching, and electrostatic discharge events.
