Product Description

STMicroelectronics SM15T22CA is a high-performance 1-Element Bi-Directional Transient Voltage Suppression (TVS) diode engineered to protect sensitive electronic circuits from voltage surges and transient energy. Packaged in a compact Surface Mount 2-Pin SMC type package, this diode delivers a peak pulse power dissipation of 1.5 kW, making it suitable for transient voltage suppression in a range of industrial, commercial, and consumer electronics applications.

This device features a single diode element with bidirectional voltage clamping capability, which protects circuits by redirecting surge energy during voltage transients. It has a minimum breakdown voltage (Vbr) of 20.9 V, a maximum reverse stand-off voltage (Vwm) of 18.8 V, and clamps voltage at 39.3 V, ensuring reliable suppression levels for both positive and negative transients.

The SM15T22CA can operate reliably across a wide temperature range from -55°C to 150°C, making it appropriate for harsh operating environments commonly found in industrial electronics, HVAC control systems, power supplies, and more. Its low maximum reverse leakage current of 1μA contributes to energy efficiency in standby applications.

Typical uses include protection of power lines, data lines, and signal lines against transient surges caused by lightning strikes, inductive load switching, and electrostatic discharge (ESD). Its peak pulse current rating of 254 A ensures it can handle high surge currents without damage.

The diode is supplied in a surface mount package measuring 7.15 mm by 6.25 mm, facilitating easy PCB assembly and high-density layouts. Although it does not comply with automotive standards, it is well-suited for industrial and consumer electronics transient voltage suppression needs.

Single diode element and bi-directional configuration. Peak pulse power rating of 1.5 kW for surge suppression. Clamping voltage 39.3 V for controlled voltage limiting. Wide operating temperature from -55°C to 150°C for reliability.

Low leakage current of 1 μA reduces power loss. Compact SMC package for surface mount assembly. Suitable for industrial, consumer electronics, and power supply protection.
