100pcs DB3 Trigger Diode DIAC 204AH DO35 Product overview A bulk pack of 100 DB3 trigger diodes (DB 3) in DIAC 204AH specification, supplied in DO35 axial package. These DIACs are intended for triggering applications in AC control circuits and for use where a consistent breakover behavior is required for triac and thyristor firing. Key benefits Bulk quantity for repairs, production runs, and prototyping: 100 pieces in one pack reduces the need for frequent reordering. Purposebuilt trigger function: DB3 DIAC devices provide a controlled breakover for triggering triacs and thyristors in AC switching and phasecontrol circuits. Standard DO35 axial package: compact, throughhole format that is easy to handle and mount on perfboards or printed circuit boards. Consistent component type: all units match the DB3 DIAC 204AH specification for predictable behavior across projects. Important attributes Model and type: DB3 (DB 3) trigger diode, DIAC 204AH. Quantity: 100pcs. Package: DO35 axial package for throughhole mounting. Function: DIAC trigger device used to initiate conduction in triacs and thyristors for AC control and switching. Typical applications Light dimmer circuits and lamp control where phase angle triggering of a triac is required. Motor speed controllers and small AC motor control circuits that rely on repeatable triggering events. DIY electronics, testing benches, and of household appliances that use triacbased AC switching. Practical notes Suitable for hobbyists, technicians, and smallscale production where a standardized DIAC component is needed. Store components in a dry environment and handle with standard ESD precautions when used in sensitive electronic assemblies.
