The SMAJ400A is a unidirectional TVS (Transient Voltage Suppression) diode from Littelfuse Inc. It is designed to protect sensitive electronic circuits from voltage transients induced by lightning and other transient voltage events. With a peak pulse power rating of 400W (10/1000μs waveform) and a maximum clamping voltage of 648V, it provides robust protection for general purpose applications.
This TVS diode features a Zener construction and is housed in a compact DO-214AC (SMA) surface mount package, suitable for automated assembly and space-constrained PCB layouts. It operates over a wide temperature range of -65°C to 150°C, ensuring reliability in harsh environments. The device is unidirectional, with a single channel for protection.
The SMAJ400A is lead-free and halogen-free, and it is rated for 1 (Unlimited) moisture sensitivity level (MSL). It is ideal for use in I/O interfaces, VCC bus, and other vulnerable circuits in telecom, computer, industrial, and consumer electronics applications.
The maximum clamping voltage is 648V under a 10/1000μs waveform.
The peak pulse current is 600mA under a 10/1000μs waveform.
The SMAJ400A is available in a DO-214AC (SMA) surface mount package.
