The SMAJ22A is a unidirectional transient voltage suppressor (TVS) diode from Bourns, part of the SMAJ series. It is designed to protect sensitive electronics from voltage transients induced by lightning, ESD, and other surge events.
Key specifications include a working peak reverse voltage of 22V, a clamping voltage of 35.5V at 11.3A peak pulse current, and a minimum peak pulse power dissipation of 400W for a 1ms pulse. The device features a fast response time of less than 1 picosecond, making it suitable for high-speed data lines.
The SMAJ22A is housed in a compact DO-214AC (SMA) surface mount package, which is compatible with standard pick-and-place assembly processes. It is RoHS compliant and UL recognized (File E153537). Typical applications include portable communications, computing, and video equipment requiring surge and ESD protection.
The working peak reverse voltage (VRWM) is 22V.
The clamping voltage is 35.5V at a peak pulse current of 11.3A.
The peak pulse current (IPP) is 11.3A.
The SMAJ22A is available in a DO-214AC (SMA) surface mount package.
The minimum peak pulse power dissipation is 400W for a 1ms pulse.
The operating junction temperature range is -55°C to 150°C.
The typical response time for unidirectional devices is less than 1 picosecond.
