The SMCJ20A-A is a high-performance Transient Voltage Suppressor (TVS) diode manufactured by SMC Diodes. As an authorised distributor, Supreme Components International provides only authentic components. This unidirectional TVS diode is designed to protect sensitive electronic circuits from voltage transients induced by lightning, electrostatic discharge (ESD), and inductive load switching. With a standoff voltage of 20V and a peak pulse power dissipation of 1500W, the SMCJ20A-A effectively clamps transient voltages to safe levels, preventing damage to downstream components. Its DO-214AB (SMC) package allows for efficient heat dissipation and easy surface mount assembly. This robust diode is ideal for use in a wide range of applications, including telecommunications, industrial equipment, and consumer electronics, where reliable overvoltage protection is critical.
