The UDZ13B is a Zener diode manufactured by Rohm Semiconductor. Zener diodes are semiconductor devices that allow current to flow in one direction, but also allow current to flow in the reverse direction when the voltage reaches a specific breakdown voltage, known as the Zener voltage. The UDZ13B is designed for voltage regulation and protection applications. The '13B' indicates a Zener voltage close to 13V.
