The SMM4F13A-TR from STMicroelectronics is a robust transient voltage suppressor (TVS) designed to protect sensitive electronics from voltage spikes and transient events. This component is part of ST's SM4F series, offering a peak pulse power of 400W (10/1000µs) and a unidirectional configuration, making it an ideal solution for safeguarding your circuits against sudden over-voltage conditions.

Key Features

• Stand-off Voltage: The device has a stand-off voltage of 13V, which means it remains non-conductive until the threshold is exceeded, ensuring normal operation of the protected device under typical voltage conditions.
• Peak Pulse Power: With a peak pulse power of 400W for a 10/1000µs waveform, the SMM4F13A-TR can absorb significant energy without damage, making it suitable for high-energy transients.
• Low Clamping Voltage: It offers a low clamping voltage, which is the maximum voltage the TVS will allow through to the protected component after the stand-off voltage is surpassed. This feature minimizes the risk of damage to sensitive circuit elements during a transient event.
• Fast Response Time: The device reacts almost instantaneously (<1ns) to transient over-voltage, providing prompt protection to the circuit components.
• Package: The SMM4F13A-TR comes in a compact, surface-mount SOD-123FL package, which is suitable for high-density circuit board designs.

Applications

The SMM4F13A-TR is versatile and can be used in a wide range of applications where transient voltage protection is critical. Common applications include:

• Portable Devices
• Power Supply Lines
• Computer Interfaces
• Telecommunication Systems
• Industrial Equipment
