Electronics.BZT52B15 with Zener Diodes SOD-123 RoHS from Yangjie Electronics is a Thyristor or Silicon Controlled Rectifier (SCR). This component is a three-terminal semiconductor device, either N-channel or P-channel type, with an internal gate terminal for control voltage. It is mainly used to control (on/off) current in circuits. The SCR can be used in multiple industries such as industrial, military, and aerospace applications for AC or pulse control circuits. This part is made RoHS compliant and has a low thermal resistance for easy heat transfer. It is manufactured in a SOD123 package, making it a compact solution. The BZT52B15 has a Zener Breakdown Voltage range of 15V DC, with a Forward Blocking Voltage rated at 25V DC. The SCR is rated to handle a maximum current of 5A and a peak non-repetitive surge current of 16A.
