Product Description
STMicroelectronics SM6T39CAY is a high-performance 1-element bi-directional TVS diode designed to protect sensitive automotive and industrial electronic circuits from transient voltage surges and electrostatic discharges. It features a peak pulse power dissipation rating of 600 W in a compact surface mount DO-214 package, which provides efficient voltage clamping for enhanced circuit reliability.
This TVS diode exhibits a minimum breakdown voltage of 37.1 V and a maximum reverse standoff voltage of 33.3 V, enabling it to absorb and dissipate surge currents up to 57 A peak pulse current safely. The device clamps voltage to a maximum of 69.7 V during transient conditions to protect circuit components downstream from damage.
Operating reliably in harsh environments, the component supports a wide temperature range from -55°C to 150°C and meets the rigorous automotive quality standard AEC-Q101. Its low maximum reverse leakage current of just 1 μA ensures minimal power loss under normal operating conditions.
The DO-214AA (SMB) package is ideal for automated surface mounting, featuring compact dimensions (4.6 mm length, 3.95 mm width, and 2.45 mm height) to support space-constrained PCB designs in automotive, industrial control, and power management applications.
