The DIOTEC SMF12CA is a surface-mount Transient Voltage Suppressor (TVS) diode designed to protect sensitive electronic circuits from voltage transients induced by lightning, electrostatic discharge (ESD), and inductive load switching. This unidirectional TVS diode features a standoff voltage of 12V and a peak pulse power dissipation of 400W. Supreme Components International is an authorised distributor of DIOTEC, ensuring you receive genuine, high-quality components. The SMF12CA is housed in a compact SMF package, making it suitable for space-constrained applications. Its fast response time and low clamping voltage provide excellent protection against overvoltage events. Typical applications include I/O protection, VCC bus protection, and data line protection.
