STMicroelectronics 1-Element Bi-Directional TVS Diode 1.5 kW, 2-Pin DO-201 1.5KE440CA

STMicroelectronics 1.5KE440CA is a 1-element bi-directional Transient Voltage Suppressor (TVS) diode designed for high-performance transient voltage protection with a peak pulse power dissipation rating of 1.5 kW. Packaged in a 2-pin through-hole DO-201 axial form factor, it provides reliable safeguarding of sensitive electronic components from voltage surges and spikes.

This diode features a minimum breakdown voltage of 418V and a maximum reverse stand-off voltage of 376V, allowing it to clamp transient voltages effectively at 776V to protect downstream electronics. Its peak pulse current capacity reaches 13A, making it suitable for absorbing large transient energy events.

Operating reliably over a wide temperature range from -65°C to 175°C, the 1.5KE440CA supports applications across demanding industrial, automotive, and power systems environments. Its low maximum reverse leakage current of 1μA ensures energy efficiency and minimal impact on the protected circuit's normal operation.

The compact axial DO-201 package measures approximately 9.5mm in length and 5.3mm in diameter, allowing easy through-hole mounting on printed circuit boards. This form factor is ideal for robust electronic assemblies requiring dependable transient voltage suppression without excessive space.

Applications include power supply surge protection, motor drives, industrial control systems, and automotive electronics where transient voltage spikes pose risks to component integrity and system reliability.
