The SMAJ78CA-H is a high-performance bidirectional Transient Voltage Suppressor (TVS) diode manufactured by Formosa Microsemi. Supreme Components International, an authorised distributor, provides this essential component for protecting sensitive electronic circuits from voltage transients induced by lightning, electrostatic discharge (ESD), and inductive load switching. This surface-mount device is housed in a compact SMA package, making it suitable for space-constrained applications. With a peak pulse power dissipation of 400W and a reverse standoff voltage of 78V, the SMAJ78CA-H effectively clamps transient voltages to safe levels, preventing damage to downstream components. Its bidirectional configuration allows it to protect circuits from both positive and negative voltage surges. This TVS diode is widely used in various applications, including telecommunications equipment, industrial controls, and consumer electronics, ensuring reliable and robust circuit protection.
