The SMAJ300CA is a bidirectional TVS diode from Littelfuse Inc., designed to protect sensitive electronic circuits from voltage transients. It offers a peak pulse power dissipation of 400W and features a reverse standoff voltage of 300V with a clamping voltage of 486V.
This device can handle peak pulse currents up to 800mA and is based on Zener technology. It is bidirectional, making it suitable for protecting against both positive and negative transient voltages. The SMAJ300CA is not intended for power line protection.
The diode is housed in a DO-214AC (SMA) surface mount package, enabling compact PCB designs. It operates over a wide temperature range from -65°C to 150°C.
Typical applications include general purpose protection of I/O interfaces, VCC bus, and other vulnerable circuits in telecom, computer, industrial, and consumer electronic devices.
