The Protectron PSMD020-1210 is a TVS (Transient Voltage Suppressor) Diode Array, specifically designed to protect sensitive electronic circuits from voltage transients induced by electrostatic discharge (ESD), electrical fast transients (EFT), and lightning. This device features 2 channels, providing protection for two separate lines. With a breakdown voltage of 20V, the PSMD020-1210 effectively clamps overvoltage events, preventing damage to downstream components. Its compact SOD-323 package makes it suitable for space-constrained applications. As an authorized distributor of Protectron components, Supreme Components International guarantees the authenticity and quality of the PSMD020-1210. This TVS diode array is commonly used in data lines, I/O ports, and other vulnerable interfaces.
