The DIOTEC P4SMAJ30CA is a Transient Voltage Suppressor (TVS) diode designed to protect sensitive electronic circuits from voltage transients induced by lightning, inductive load switching, and electrostatic discharge (ESD). This bidirectional TVS diode features a standoff voltage of 30V and a power dissipation of 400W, providing robust protection against overvoltage events. Housed in a surface-mount SMA package, the P4SMAJ30CA is easy to integrate into existing designs. As an authorised distributor of DIOTEC components, Supreme Components International guarantees the authenticity and quality of this product. This diode is suitable for a wide range of applications, including telecommunications, industrial equipment, and consumer electronics, where reliable voltage surge protection is critical. Its bidirectional characteristic makes it versatile for AC and DC circuit protection.
