STMicroelectronics SM6T22CA Transil™ TVS Diode

The SM6T22CA is a robust transient voltage suppression (TVS) diode from STMicroelectronics, designed to protect sensitive electronic equipment from voltage transients induced by system inductance, lightning, and other transient voltage events. This product is part of the Transil™ series, which are bidirectional TVS diodes that offer a high level of surge protection in a compact package.

The SM6T22CA TVS diode features a stand-off voltage of 18.8V, making it suitable for a range of applications that require protection against overvoltage conditions. It is capable of clamping voltage spikes and is designed to respond to overvoltages quickly, ensuring the safety of the downstream components. The peak pulse power dissipation of this device is 600W (10/1000μs surge), sufficient to handle significant surge events without damage.

Engineered for reliability, the SM6T22CA comes in a DO-214AA package, also known as SMB, which is a surface-mount package that allows for efficient PCB layout and is compatible with automated assembly processes. This package is widely recognized for its ease of integration into various circuit designs.

The versatility of the SM6T22CA makes it an ideal choice for a range of applications, including but not limited to power supply protection, telecommunications systems, computer interfaces, and other electronic devices that are exposed to the risk of electrostatic discharges (ESD) and electrical over stress (EOS).

Key features of the SM6T22CA include:

• Stand-off voltage: 18.8V
• Peak pulse power: 600W (10/1000μs)
• Breakdown voltage range: 20.9V to 23.1V
• Low clamping factor
• Fast response time
• Operating junction temperature range: -55°C to +150°C
• Compliance with IEC 61000-4-2 and IEC 61000-4-5 surge immunity tests

STMicroelectronics is known for its commitment to quality and reliability, and the SM6T22CA is no exception. It is a testament to ST's dedication to providing components that enhance the durability and longevity of electronic systems.
