The SMAJ40A is a 400W Transient Voltage Suppressor (TVS) diode from Littelfuse Inc., designed for surge and ESD protection in portable communications, computing, and video equipment. It features a standoff voltage of 40V and a maximum clamping voltage of 64.5V.
This unidirectional device is housed in a compact, surface mount DO-214AC (SMA) package, making it suitable for automated assembly. Key electrical characteristics include a peak pulse power dissipation of 400W (10/1000 µs waveform), a peak pulse current of 6.2A, and a peak forward surge current of 40A (8.3 ms).
The SMAJ40A operates over a junction temperature range of -55°C to +150°C and is RoHS compliant. It provides reliable circuit protection against voltage transients in a wide range of general-purpose applications.
