The SM6T150CA is a high-quality Transil™ transient voltage suppression (TVS) diode designed and manufactured by STMicroelectronics. This robust component is engineered to protect sensitive electronic equipment from voltage transients induced by system inductance, load dump, and lightning. With its bi-directional clamping feature, it is particularly suitable for AC applications where a symmetrical protection is required.

Key Features

• Stand-off Voltage: The SM6T150CA has a stand-off voltage of 150V, making it suitable for a wide range of applications that require high voltage protection.
• Peak Pulse Power: It can handle peak pulse power dissipation of 600W (10/1000μs), ensuring reliable protection against high energy transients.
• Low Clamping Voltage: The device offers a low clamping voltage relative to its stand-off voltage, which minimizes the stress on the protected component during a transient event.
• Fast Response Time: With a response time of less than 1 picosecond from 0V to BV min, the SM6T150CA can quickly react to transient overvoltages, offering immediate protection.
• Package: Available in a DO-214AA (SMB) package, it provides a compact solution for PCB layouts.
• Operating Temperature Range: It operates within a temperature range of -55°C to +150°C, suitable for a variety of harsh environmental conditions.
