Product Description
STMicroelectronics SM6T42CAY is a high-performance 1-element bi-directional Transient Voltage Suppressor (TVS) diode designed to protect electronic equipment against voltage surges and electrostatic discharge events. The diode is surface mount packaged in a DO-214 (SMB) form factor, making it suitable for automated assembly in modern electronics manufacturing.
This device is rated to absorb peak pulse power surges of up to 600 W, making it effective for transient voltage suppression in automotive and industrial electronic circuits. It provides a clamping voltage of 76 V, limiting voltage spikes that could otherwise damage sensitive components.
The SM6T42CAY is specifically engineered for automotive applications with AEC-Q101 qualification, ensuring compliance with rigorous quality and reliability standards required for vehicle electronics.
Its bidirectional configuration allows protection of circuits against both positive and negative surge voltages in a compact and lightweight surface mount package. The typical operating temperature range extends from -55°C to 150°C, enabling operation in harsh environmental conditions.
Physical dimensions of 4.6 mm length, 3.95 mm width, and 2.45 mm height make this diode suitable for space-constrained board designs while maintaining excellent electrical characteristics.
Single element diode designed for bidirectional voltage protection. Voltage breakdown minimum at 40 V and maximum reverse stand-off voltage of 36 V. Clamping voltage is 76 V to protect circuits against surges. Peak pulse current capability up to 52 A for transient suppression.
Operating temperatures range from -55°C to 150°C support automotive and industrial use. Compact surface mount DO-214 (SMB) package supports automated PCB assembly. AEC-Q101 automotive qualification ensures high reliability under severe conditions.
Very low leakage current of 1 μA reduces standby power loss. Test current of 1 mA ensures device performance verification. Protects circuits from ISO 7637-2 and ISO 10605 transient standards.
This TVS diode is ideal for industrial, automotive, and commercial electronics to safeguard voltage-sensitive devices, including microcontrollers, sensors, and communication modules. Using SM6T42CAY enhances circuit robustness against transient voltage spikes in harsh electrical environments.
