Specification

Description

The DB3 is a commonly used DIAC (Diode for Alternating Current) trigger diode.

Here's a brief description of its characteristics:

Type: DIAC (Diode for Alternating Current).

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.

Application:

The DB3 is widely used in various AC switching applications, including phase control, light-dimming circuits, motor speed control, and inrush current limiting.
