Product Description
STMicroelectronics SM15T27A is a high-performance uni-directional transient voltage suppression (TVS) diode designed for protecting sensitive electronic components from transient voltage surges and spikes. Featuring a single element configuration and housed in a surface mount SMC package, this diode provides robust protection with a peak pulse power dissipation rating of 1.5 kW.
The diode offers a minimum breakdown voltage (Vbr) of 25.7 V and a maximum reverse stand-off voltage (Vwm) of 23.1 V, making it suitable for circuits requiring reliable clamping against transient events. The clamping voltage of 48.3 V ensures that voltage spikes are quickly suppressed to safe levels, protecting downstream circuitry.
Designed for a wide range of operating environments, the SM15T27A operates reliably from -55°C to 150°C, with a maximum peak pulse current capacity of 207 A. Its low maximum reverse leakage current of 1 μA guarantees minimal power loss during normal operation.
Compact in size, with dimensions 7.15 mm long, 6.25 mm wide, and 2.45 mm high, this diode is optimized for surface-mount technology (SMT) assembly, promoting space-saving PCB design and easy integration.
The device is widely used in industrial electronics, power supply protection, telecommunications, automotive electronics (non-automotive standard), and other commercial electronic systems needing effective transient voltage protection.
This device provides uni-directional transient voltage suppression. Single element design enhances reliability and performance. Compact SMC surface mount package ideal for PCB layout optimization. High peak pulse power rating of 1.5 kW for robust transient handling.
Wide operating temperature range (-55°C to 150°C) supports harsh environments. Minimal leakage current (max 1 μA) for efficient normal operation. Suitable for industrial, commercial, and power electronics applications requiring voltage spike protection.
