DB3 DIAC TRIGGER DIODE
Operation: The DIAC is a bidirectional semiconductor switch that conducts current only after its breakdown voltage is exceeded. It is commonly used in triggering thyristors and triacs in phase control and light-dimming applications.
Breakdown Voltage (VBO): The DB3 typically has a breakdown voltage ranging from 28 volts to 36 volts, depending on the specific model and manufacturer.
Peak Forward Current (IPP): It can handle peak forward currents in the range of a few amperes.
Peak Repetitive Off-State Voltage (VDRM): Typically around 30 volts to 38 volts.
Package Type: The DB3 is commonly available in a DO-35 package, which is a small glass-encapsulated diode package.
