The DIPTRONICS SMF18A is a surface-mount Transient Voltage Suppressor (TVS) diode. Supreme Components International is an authorised distributor of DIPTRONICS components, ensuring you receive genuine and high-quality products. This diode is specifically designed to protect sensitive electronic devices from voltage transients caused by electrostatic discharge (ESD), lightning, and other transient voltage events. The SMF18A features a reverse standoff voltage of 18V and a peak pulse power dissipation of 400W. It is housed in a compact DO-219AB (SMF) package, making it suitable for space-constrained applications. This TVS diode offers fast response times and low clamping voltage, providing effective protection for your circuits. Its robust construction ensures reliable performance in demanding environments. Applications include I/O protection, VCC bus protection, and control line protection.
