The P4SMF70A is a Transient Voltage Suppressor (TVS) diode from SMC DIODES, available at Supreme Components International, an authorised distributor. This diode is designed to protect sensitive electronic circuits from voltage transients induced by lightning, electrostatic discharge (ESD), and inductive load switching. With a reverse standoff voltage of 70V and a peak pulse power dissipation of 400W, the P4SMF70A effectively clamps transient voltages to safe levels, preventing damage to downstream components. Its DO-214AC (SMA) package allows for easy surface mounting. Typical applications include I/O protection, VCC bus protection, and protection of data lines. Supreme Components International guarantees the authenticity and quality of this SMC DIODES product.
