The SMAJ440A is a unidirectional transient voltage suppressor (TVS) diode designed for surge and ESD protection in electronic circuits. It features a standoff voltage of 440V and a breakdown voltage of 491V, clamping transient overvoltages to 713V. With a peak pulse power dissipation of 400W (1 ms pulse) and a peak pulse current of 600mA, it provides robust protection for sensitive components.
This TVS diode is housed in a compact DO-214AC (SMA) surface mount package, suitable for automated assembly. It operates over a junction temperature range of -65°C to 150°C and is RoHS compliant. The device is unidirectional with a single protection channel and does not include power line protection.
Typical applications include general purpose circuit protection in computing, communications, and industrial equipment. The SMAJ440A is part of the Bourns SMAJ series (though listed under Littelfuse), offering fast response times less than 1.0 ps for unidirectional types.
The standoff voltage (working peak reverse voltage) is 440V.
The breakdown voltage is 491V (nominal).
The clamping voltage is 713V.
The peak pulse current is 600mA (0.6A).
The SMAJ440A is available in a DO-214AC (SMA) surface mount package.
The operating temperature range is -65°C to 150°C (junction).
