The PDZVTR13B is a Pd (Power Dissipation) 1000mW, Zener 10uA, 150C SOD-128 manufactured by ROHM which is a type of a Zener diode. It is used to regulate voltage in electronic circuits by allowing the current to pass in one direction, but when the voltage exceeds the set level, the diode kicks in and regulates it. The PDZVTR13B has a power dissipation rating of 1000mW and a Zener current of 10 uA with a maximum temperature rating of 150C in a SOD-128 package. Its working characteristics are designed to offer excellent reliability at a low price.
