Product Overview: SMM4F10A-TR by STMicroelectronics

The SMM4F10A-TR is a robust and versatile transient voltage suppressor (TVS) diode, designed and manufactured by STMicroelectronics, a global semiconductor leader known for its commitment to delivering high-performance and energy-efficient solutions. This TVS diode is specifically engineered to protect sensitive electronic equipment from voltage transients induced by system inductance, lightning, and electrostatic discharge (ESD), making it an ideal choice for a wide range of applications.

Key Features

• Stand-off Voltage: The device has a stand-off voltage of 10V, which is the maximum voltage that can be applied over the diode without causing it to conduct in avalanche breakdown.
• Peak Pulse Power Dissipation: With its ability to handle peak pulse power dissipation of 400W (10/1000μs), the SMM4F10A-TR can effectively clamp and withstand high transient power spikes.
• Low Clamping Voltage: The low clamping voltage ensures that the protected component sees a reduced stress voltage during transient conditions.
• Fast Response Time: Its fast response time to transient over-voltages guarantees swift protection for sensitive circuits.
• Low Leakage Current: The device is characterized by its low leakage current, which enhances the overall energy efficiency of the system it protects.
• Package: Housed in a small and flat SOD-123FL package, the SMM4F10A-TR is designed for surface-mount applications and is compatible with high-volume assembly lines.
• AEC-Q101 Qualified: Meeting the requirements of the AEC-Q101 standard, this TVS diode is suitable for automotive applications where reliability under harsh conditions is paramount.
