The SMAJ43A-TR is a 400W unidirectional TVS diode manufactured by STMicroelectronics. It is designed to protect sensitive electronic circuits from voltage transients and surges. The device features a reverse standoff voltage of 43V and a maximum clamping voltage of 91V, ensuring that downstream components are protected from overvoltage events.
With a peak pulse power dissipation of 400W and a peak pulse current rating of 25A (8/20µs waveform), this TVS diode provides robust transient suppression for general purpose applications. It operates over a wide temperature range of -55°C to 150°C, making it suitable for various environmental conditions.
The SMAJ43A-TR is housed in a surface mount DO-214AC (SMA) package, allowing for compact PCB designs and automated assembly. It is not intended for power line protection but is ideal for protecting signal lines and low voltage power rails in consumer, industrial, and automotive electronics.
