The SMAJ18A-TR from STMicroelectronics is a unidirectional transient voltage suppression (TVS) diode rated for 400W peak pulse power (8/20µs waveform). It provides a clamping voltage of 39.3V at a peak pulse current of 59A, making it suitable for protecting sensitive electronics from voltage transients. The device features a standoff voltage of 18V and is housed in a surface-mount DO-214AC (SMA) package. It operates over a temperature range of -55°C to 150°C and is designed for general purpose applications. The component offers one unidirectional channel and does not include power line protection.
