The SMAJ40A-H TVS diode, manufactured by Formosa Microsemi, provides robust overvoltage protection for sensitive electronic circuits. This unidirectional diode clamps voltage transients at 40V and can handle peak pulse power dissipation of 400W. Its fast response time and low clamping voltage make it ideal for safeguarding against ESD, EFT, and lightning surges. Housed in a compact SMA package, the SMAJ40A-H is easy to integrate into existing designs. Supreme Components International is an authorized distributor of Formosa Microsemi, guaranteeing the authenticity and quality of this TVS diode. Applications include I/O protection, VCC bus protection, and control line protection.
