The SMA6T39AY is a 600W unidirectional TVS diode designed by STMicroelectronics for automotive applications. It features a reverse standoff voltage of 33.3V and a clamping voltage of 69.7V, providing robust protection against voltage transients. The device can handle a peak pulse current of 57A under an 8/20µs waveform.
This TVS diode is housed in a compact DO-214AC (SMA) surface-mount package, making it suitable for space-constrained designs. It operates over a wide temperature range from -40°C to 150°C, ensuring reliability in harsh environments. The single-channel unidirectional configuration is ideal for protecting sensitive circuits in automotive electronics.
With its 600W peak pulse power rating, the SMA6T39AY offers effective transient suppression for automotive systems such as engine control units, infotainment, and sensor interfaces. The surface-mount SMA package facilitates automated assembly and reduces board space requirements.
