Product Description
STMicroelectronics SM15T220CA is a high-performance 1-Element Bi-Directional Transient Voltage Suppressor (TVS) diode designed to protect sensitive electronic components from voltage spikes caused by inductive load switching, lightning, and other transient disturbances.
This TVS diode provides a peak pulse power dissipation of 1.5 kW, ensuring reliable clamping of voltage surges to safe levels. Its bi-directional configuration is particularly suited for AC signal lines and circuits where voltage spikes may occur in either polarity.
The device is housed in a compact 2-pin surface mount SMC package measuring 7.15 mm in length, 6.25 mm in width, and 2.45 mm in height, facilitating easy placement on PCBs designed for automated assembly. It operates effectively within a temperature range of -55°C to 150°C.
Electrical specifications include a minimum breakdown voltage (Vbr) of 209 V, a maximum reverse standoff voltage (Vwm) of 188 V, and a maximum peak pulse current (Ippm) of 26 A, with a clamping voltage (Vc) of 388 V. The maximum reverse leakage current is low at 1 μA, contributing to energy efficiency and circuit stability.
Because it has a single element per chip, the SM15T220CA maintains consistent performance and reliability expected in industrial, telecommunications, automotive, and consumer electronics applications.
