STMicroelectronics SM15T24CA Transient Voltage Suppressor (TVS)

The SM15T24CA is a robust transient voltage suppressor (TVS) diode designed by STMicroelectronics, a global semiconductor leader. This TVS diode is specifically engineered to protect sensitive electronic equipment from voltage transients induced by system load dump and other transient voltage events. The SM15T24CA is part of the SM15T series, which is characterized by its high surge capability and fast response time, making it an ideal choice for a wide range of applications.

Key Features

• Stand-off Voltage: The device has a stand-off voltage of 24V, which is the maximum voltage that can be applied over the TVS without causing it to conduct significant current.
• Peak Pulse Power: It can handle peak pulse power dissipation of 1500W (10/1000μs surge), providing protection against high energy transients.
• Clamping Voltage: The SM15T24CA has a clamping voltage of 38.9V, ensuring that the voltage to the protected component does not exceed this value during transient conditions.
• Bidirectional Device: As a bidirectional TVS, it can protect circuits from surges that may occur in both directions along the protected line.
• Low Leakage Current: The device maintains a low leakage current under normal operating conditions, thereby conserving energy and ensuring minimal impact on the system’s performance.
• Package: Offered in an industry-standard DO-214AB (SMC) package, it is compatible with typical PCB layout and assembly processes.
• Compliance: It meets the ISO 7637-2 and ISO 16750-2 standards for automotive load dump protection and is RoHS and Halogen-free compliant.
