The DIOTEC P4SMAJ40A is a high-performance, unidirectional Transient Voltage Suppressor (TVS) diode designed for robust circuit protection. This surface-mount device, housed in an SMA package, offers a peak pulse power dissipation of 400W and a reverse standoff voltage of 40V. It effectively clamps transient voltages, safeguarding sensitive electronic components from damage caused by electrostatic discharge (ESD), inductive switching, and other transient voltage events. Supreme Components International is an authorised distributor of DIOTEC, ensuring you receive authentic and reliable components. The P4SMAJ40A is ideal for applications in telecommunications, industrial control, consumer electronics, and automotive systems where transient voltage protection is critical. Its unidirectional configuration provides optimal protection for DC circuits. Benefit from its fast response time and low clamping voltage for superior circuit protection.
