The P4SMA9.1CA is a high-performance Transient Voltage Suppressor (TVS) Diode manufactured by JSCJ (JCET). This bidirectional TVS diode is specifically designed to protect sensitive electronic equipment from voltage transients induced by lightning, electrostatic discharge (ESD), and inductive load switching. Featuring a breakdown voltage of 9.1V and a power dissipation capability of 400W, the P4SMA9.1CA effectively clamps transient voltages to safe levels, preventing damage to downstream components. Its SMA (Surface Mount Assembly) package allows for easy integration into printed circuit boards. Supreme Components International is an authorised distributor of JSCJ (JCET) components, ensuring you receive a genuine and reliable product. Ideal for use in telecommunications, industrial control, and consumer electronics applications.
