The P4SMA70A is a Transient Voltage Suppressor (TVS) Diode manufactured by Central Semiconductor. Supreme Components International is an authorised distributor of Central Semiconductor components. This diode is designed to protect sensitive electronic circuits from voltage transients induced by lightning, inductive load switching, and electrostatic discharge (ESD). It features a power dissipation of 400W and a standoff voltage of 70V. The P4SMA70A is housed in a compact SMA package, making it suitable for space-constrained applications. Its fast response time and low clamping voltage ensure effective protection against transient events. Applications include I/O protection, VCC bus protection, and protection of data lines.
