The SM2T14A is a robust transient voltage suppression (TVS) diode from STMicroelectronics, designed to shield sensitive electronic equipment from voltage spikes and transients induced by lightning and other transient voltage events. This component is part of ST's Transil™ series, which is renowned for providing high surge protection in compact packages.

Key Features

• Stand-off Voltage: The SM2T14A has a stand-off voltage of 14V, making it suitable for a range of applications that require protection at this voltage level.
• Peak Pulse Power: It can handle a peak pulse power of 600W (10/1000µs), ensuring reliable protection against high energy transients.
• Low Clamping Voltage: The low clamping voltage of this device ensures that any transient voltage spike is clamped down to a safe level, protecting the downstream circuitry.
• Fast Response Time: With its fast response time to transient events, the SM2T14A minimizes the risk of damage to sensitive components.
• Unidirectional: As a unidirectional TVS diode, it is optimized for DC applications where the protection is required in one direction only.

Applications

The SM2T14A is versatile and can be used in a variety of applications. It is commonly employed in consumer electronics, such as smartphones and tablets, to protect against electrostatic discharges (ESD). It is also suitable for use in industrial systems, telecommunications, and automotive electronics, where equipment is regularly exposed to high transient voltages.

Package and Installation

Housed in a compact DO-214AA (SMB) package, the SM2T14A is designed for surface mount applications, allowing for efficient use of PCB space. Its small form factor and ease of installation make it an ideal choice for dense circuit designs.

Reliability and Compliance

STMicroelectronics ensures that the SM2T14A meets rigorous standards for reliability and performance. It is compliant with industry standards, including IEC 61000-4-2 for ESD protection and IEC 61000-4-5 for surge immunity. This guarantees that the device is not only effective but also reliable for long-term use in critical applications.
