Product Description
STMicroelectronics SM15T18CA is a 1-element bi-directional transient voltage suppressor (TVS) diode designed for surface mount assembly in a 2-pin SMC package. It provides robust protection against voltage spikes with a peak pulse power dissipation of 1.5 kW, making it well suited for safeguarding sensitive electronic circuits.
With a minimum breakdown voltage of 17.1 V and maximum reverse stand-off voltage of 15.3 V, this diode clamps surge voltages effectively to a maximum clamping voltage of 32.5 V. The diode supports a maximum peak pulse current of 308 A, allowing it to endure high transient currents during voltage surges.
The component operates reliably across a wide temperature range from -55°C to 150°C, suitable for demanding automotive, industrial, and power electronics applications. Its compact SMC surface mount package (7.15 mm x 6.25 mm x 2.45 mm) offers easy mounting on printed circuit boards with excellent electrical and mechanical stability.
This diode features a bi-directional configuration, providing symmetrical surge suppression for both polarities. The low maximum reverse leakage current of 1 μA ensures minimal power loss during normal operation.
It serves critical protection roles in electronic equipment, manufacturing, power supply lines, and other environments requiring transient voltage spike suppression and surge protection.
STMicroelectronics SM15T18CA complies with standard quality and manufacturing processes but does not carry specific certified automotive standards. It belongs to the SM15T TVS series, renowned for reliability and performance in transient voltage suppression.
Bi-directional TVS diode with 1.5 kW peak power dissipation. Surface mount 2-pin SMC package for compact, automated PCB assembly. Breakdown voltage: 17.1 V min; clamping voltage: 32.5 V max. Operates across -55°C to 150°C temperature range.
Designed for protecting electronics from transient voltage surges. Explore more semiconductors and TVS Diode solutions at EnvMart for industrial, automotive, and electronic component applications.
