The DIPTRONICS SMF12A is a surface-mount Transient Voltage Suppressor (TVS) diode housed in a compact SOD-123FL package. This diode is engineered to safeguard sensitive electronic equipment from voltage transients induced by electrostatic discharge (ESD), electrical fast transients (EFT), and lightning. With a standoff voltage of 12V and a peak pulse power dissipation of 400W, the SMF12A provides robust overvoltage protection. Supreme Components International is an authorised distributor of DIPTRONICS components, ensuring you receive genuine and high-quality products. This TVS diode is suitable for a wide range of applications, including automotive, industrial, and consumer electronics, where reliable surge protection is critical. Its small form factor and high performance make it an excellent choice for space-constrained designs.
