SMBJ40CA Description

Short technical summary and product information.

The SMBJ40CA is a surface-mount Transient Voltage Suppression (TVS) diode designed by Lite-On Inc. to protect sensitive electronic equipment from voltage transients. It features a 40V standoff voltage and a 600W peak pulse power dissipation capability, making it suitable for protecting I/O interfaces and VCC buses.

 

This TVS diode is housed in a DO-214AA package, designed for surface-mounted applications to optimize board space. It offers excellent clamping capability and a fast response time, crucial for safeguarding delicate circuitry against lightning-induced transients and other voltage events.

 

The SMBJ40CA operates within a temperature range of -65°C to 150°C. It is constructed with a glass-passivated die and is RoHS compliant, with a green molding compound that contains no halogen and antimony.
