Bourns SMLJ43A Transient Voltage Suppressor Diode

Bourns SMLJ43A Transient Voltage Suppressor Diodes are designed to protect sensitive electronic components from voltage surges and electrostatic discharge (ESD). These diodes, packaged in a compact SMC/DO-214AB format, offer a choice of working peak reverse voltage from 5V up to 170V and breakdown voltage up to 200V. They are commonly used in portable communications, computing, and video equipment to ensure reliable operation and prevent damage from transient events. The devices are easy to handle with standard pick and place equipment and their flat configuration minimizes roll away. They conform to JEDEC standards and are RoHS compliant.
