The Bourns SMAJ440A is a unidirectional transient voltage suppressor diode designed for surge and ESD protection in electronic circuits. It features a reverse standoff voltage of 440V and a maximum clamping voltage of 713V, ensuring downstream components are protected from overvoltage events.
With a peak pulse power rating of 400W (10/1000µs waveform) and a peak pulse current of 600mA, this device is suitable for general purpose circuit protection applications. The DO-214AC (SMA) surface mount package enables automated assembly and compact board design.
The SMAJ440A operates over a junction temperature range of -55°C to +150°C and is RoHS compliant. It is part of the Bourns SMAJ series, which offers standoff voltages from 5V to 495V.
