The SMAJ40A-TR is a unidirectional transient voltage suppression (TVS) diode manufactured by STMicroelectronics. It is designed to protect sensitive electronic circuits from voltage transients induced by lightning, inductive load switching, and electrostatic discharge.
Key electrical specifications include a reverse standoff voltage of 40V, a clamping voltage of 84V, and a peak pulse current rating of 27A under an 8/20µs waveform. The device can handle 400W of peak pulse power. It uses Zener technology and does not include power line protection.
The SMAJ40A-TR is housed in a surface-mount DO-214AC (SMA) package, suitable for automated assembly. It operates over a junction temperature range of -55°C to 150°C. This component is intended for general-purpose transient protection applications.
