Diac Db2 Datasheet Pdf 14 Top [better] Jun 2026

This article provides an in-depth analysis of the DB2 DIAC, focusing on its technical specifications, the 14 top parameters found in its datasheet, and its role in modern electronics. 1. What is a DB2 DIAC?

: An AC voltage builds across the DIAC within a circuit.

: These components cannot be tested with a standard multimeter "diode check" because their conduction threshold (typically is greater than 28 cap V ) exceeds the meter's battery voltage. Specifications (Typical for DBx Series) diac db2 datasheet pdf 14 top

(Breakover Current): The current flowing through the DIAC at the moment it breaks over, typically in the range of 10-50μA. VFcap V sub cap F

(Operating Junction Temperature): Typically -40°C to +125°C. This article provides an in-depth analysis of the

The is almost always paired with a TRIAC (e.g., BT136, BT139) to form a phase-control circuit. Here is a simplified sequence:

TRIACs, which handle the heavy lifting of AC power, are notoriously "finicky." They don't always trigger symmetrically on both halves of an AC cycle, leading to flickering lights or uneven motor speeds. : An AC voltage builds across the DIAC within a circuit
