The SMAJ19CA is a high-reliability, surface-mount Transient Voltage Suppressor (TVS) diode manufactured by JSCJ (JCET). This bidirectional TVS diode is specifically designed to protect sensitive electronic equipment from voltage transients caused by inductive load switching, lightning strikes, and electrostatic discharge (ESD). Featuring a standoff voltage of 19V and a peak pulse power dissipation of 400W, the SMAJ19CA effectively clamps transient voltages to safe levels, preventing damage to downstream components. Its compact SMA package makes it suitable for space-constrained applications. Supreme Components International is an authorised distributor of JSCJ (JCET) components, ensuring you receive genuine, high-quality products. This TVS diode is ideal for protecting I/O interfaces, VCC bus lines, and other vulnerable circuits in various electronic devices.
