STMicroelectronics SM15T47AY Transil™ Surge Protector

The SM15T47AY is a robust transient voltage suppressor (TVS) diode from STMicroelectronics, designed to provide high-quality surge protection in a compact package. This device is part of the Transil™ series, known for their ability to protect sensitive electronics against voltage transients induced by system level events and other external surge events.

Key Features

• Stand-off Voltage: The SM15T47AY offers a stand-off voltage of 47V, making it suitable for a wide range of applications where this voltage level is required for safe operation.
• Peak Pulse Power: It can handle peak pulse power dissipation of 1500W at 10/1000µs, providing reliable protection against high energy transients.
• Low Clamping Voltage: The low clamping voltage ensures that even when a surge occurs, the voltage presented to the protected component will not exceed a safe level, thereby preventing damage.
• High Surge Capability: Designed to handle high surge capabilities, this device is capable of protecting against severe transient events.
• Unidirectional Protection: The SM15T47AY is a unidirectional TVS, offering protection in one direction, which is ideal for DC applications where the polarity is fixed.
• Package: Available in a molded JEDEC SMB package, it is designed for surface mount application, offering a compact footprint for space-constrained designs.
• Compliance: It complies with industrial standards such as ISO 7637-2 and MIL-STD 883, Method 3015, ensuring reliability and performance in harsh environments.
