Product Overview: SM15T82AY Transient Voltage Suppressor (TVS) Diode

The SM15T82AY is a robust transient voltage suppressor (TVS) diode designed by STMicroelectronics, a leader in semiconductor solutions. This product is specifically engineered to protect sensitive electronic equipment from voltage transients induced by system inductance, lightning, and other transient voltage events.

Key Features

• Stand-off Voltage: The device has a stand-off voltage of 82V, which is the maximum voltage that the TVS can tolerate without conducting significant current.
• Peak Pulse Power: It offers a peak pulse power dissipation of 1500W (10/1000μs surge), ensuring protection against high energy transients.
• Breakdown Voltage: The breakdown voltage ranges from 91.1V to 100.9V, providing a margin above the stand-off voltage to prevent leakage current during normal operation.
• Low Clamping Voltage: Upon encountering a voltage spike, the SM15T82AY clamps to a low voltage, reducing the stress on the protected component.
• Uni-directional Design: This component is uni-directional, making it suitable for DC voltage applications where protection is required in one direction only.
• Package: It comes in a molded plastic over glass passivated junction in a DO-214AB (SMC) package which is designed for surface mount applications.
• Compliance: The SM15T82AY meets ISO 7637-2 pulse 5a and 5b, and it is compliant with RoHS and Halogen-Free standards.
