Product Description
The STMicroelectronics 1.5KE30A is a single-element, uni-directional Transient Voltage Suppressor (TVS) diode engineered for protecting sensitive electronic components against transient voltage spikes and surges. Featuring a peak pulse power dissipation of 1.5 kW, this diode is capable of absorbing high transient energy, thereby safeguarding circuits in industrial, automotive, and consumer electronics applications.
Offered in a DO-201 axial through-hole package with two pins, the device measures 9.5 mm in length and 5.3 mm in diameter, making it suitable for PCB-level protection where size constraints exist. Its minimum breakdown voltage is rated at 28.5 V, with a maximum reverse standoff voltage of 25.6 V, ensuring it activates precisely before damaging voltage levels are reached. The clamping voltage of 53.5 V provides effective suppression of voltage transients.
Designed to operate reliably across a temperature range of -65°C to 175°C, it can function in demanding environmental conditions. It handles a maximum peak pulse current of 187 A, making it capable of enduring sudden high-energy surges typically encountered in power regulation and industrial equipment.
This component does not provide ESD protection but serves primarily as a transient voltage suppressor, ideal for industrial power supplies, automotive electronics, communications infrastructure, and other semiconductor protection needs.
