STMicroelectronics SM6T15A Transil™ TVS Diode

The SM6T15A from STMicroelectronics is a Transil™ transient voltage suppression (TVS) diode designed to protect sensitive electronic equipment from voltage transients induced by load dump and other transient voltage events. This high-quality TVS diode is specifically engineered to dissipate high transient power and clamp voltage to a safe level, ensuring the protection of integrated circuits and other sensitive components.

Key Features

• Stand-off Voltage: The SM6T15A has a stand-off voltage of 15V, making it suitable for a range of applications where this voltage level is common.
• Peak Pulse Power: It offers a peak pulse power dissipation of 600W (10/1000μs surge), able to handle significant power spikes.
• Low Clamping Voltage: With a low clamping voltage, the SM6T15A ensures that the voltage seen by the protected component does not exceed a safe level during transient conditions.
• Fast Response Time: The device responds to overvoltage events in less than 1 picosecond, providing immediate protection for connected electronics.
• Unidirectional Protection: This TVS diode offers unidirectional transient voltage suppression, ideal for DC power line applications.
• Compliance: It complies with the following standards: IEC 61000-4-2 (ESD), IEC 61000-4-4 (EFT), and IEC 61000-4-5 (Surge).
