Additional Infomation About Product

The SMAJ40A is a RoHS-compliant surface-mount Transient Voltage Suppressor (TVS) diode made by Formosa. It is packaged in a DO-214AC form factor and is designed to protect sensitive components from voltage transients that may be produced by electrical overstress (EOS). The SMAJ40A is typically used in voltage clamping, power supply sequencing, and overvoltage protection applications. Its ultra-low leakage current and fast response time make it well-suited for high-current/high-frequency applications where ESD protection is needed. The SMAJ40A also has excellent surge capability and a thermal resistance of 0.35 °C/W.
