STMicroelectronics SM15T22A Transil™ TVS Diode

The SM15T22A is a robust Transil™ transient voltage suppressor (TVS) diode designed by STMicroelectronics to protect sensitive electronics from voltage transients induced by load dump and other transient voltage events. This device is specifically crafted to safeguard circuits against surges defined in the IEC 61000-4-2 and ISO 7637-2 standards, making it an ideal choice for automotive, industrial, and other harsh-environment applications.

With its stand-off voltage of 22V and a peak pulse power dissipation of 1500W (10/1000μs), the SM15T22A ensures reliable operation and protection for connected components. The bidirectional device offers clamping characteristics that are essential in protecting sensitive circuitry by limiting overvoltages to a safe threshold.

Key Features:

• Peak Pulse Power: 1500 W (10/1000μs)
• Stand-off Voltage: 22V
• Breakdown Voltage: 24.4V to 26.9V
• Clamping Voltage: 35.5V at 50A (8/20μs)
• Package: SMB (DO-214AA)
• Operating Junction Temperature Range: -40°C to +150°C
• Compliance: Meets IEC 61000-4-2 and ISO 7637-2 standards
• RoHS Compliant: Yes

The SM15T22A's low clamping voltage combined with its fast response time ensures that voltage spikes are suppressed before they can cause any damage. The device's rugged design allows it to withstand repetitive surges and pulses over its operational life, providing a reliable shield for electronic components.

Available in an SMB (DO-214AA) package, the SM15T22A is not only powerful but also compact, making it suitable for space-constrained applications. It is also RoHS compliant, ensuring that it meets the latest environmental standards for electronic components.

Whether you are designing automotive electronics, power supplies, or other critical systems that require robust protection against electrical transients, the SM15T22A from STMicroelectronics offers a trusted solution for safeguarding your circuits from unpredictable voltage spikes.
