Product Description
STMicroelectronics 1.5KE440A 1-Element Uni-Directional TVS Diode is a robust transient voltage suppressor designed to protect electronic circuits from damaging voltage surges. Featuring a single-element diode configuration and uni-directional operation, it offers reliable and precise voltage clamping to safeguard sensitive components in various industrial and commercial applications.
This diode provides a peak pulse power dissipation of 1.5 kW, making it suitable for high surge energy environments. It is housed in a DO-201 package, which is a through-hole mount type, facilitating easy integration into printed circuit boards.
The device has a minimum breakdown voltage (Vbr) of 418 V and a maximum reverse stand-off voltage (Vwm) of 376 V, protecting circuits from transient voltages exceeding these thresholds. The maximum clamping voltage is 776 V, ensuring effective suppression of voltage spikes.
Designed to operate reliably across a wide temperature range from -65°C to 175°C, this TVS diode is well-suited for harsh industrial environments including power supply boards, communication equipment, automotive electronics, and other high-reliability systems.
Physical dimensions are compact with a length of 9.5 mm, diameter and width both 5.3 mm, enabling use in space-constrained applications. Rated for a maximum peak pulse current of 13 A and exhibiting a low maximum reverse leakage current of 1 μA, the diode maintains energy efficiency while providing surge protection.
This single-element device lacks ESD protection but excels in transient voltage suppression functions.
Packaged individually, this device fits seamlessly into automated or manual assembly workflows. It is commonly deployed in industrial, laboratory, and electronic component manufacturing sectors to enhance product durability and prevent circuit failures due to voltage spikes.
