Diac Db2 Datasheet Pdf 14 Top ((top)) Jun 2026

While a standalone DB2 datasheet can be elusive, manufacturers of DIACs often provide comprehensive datasheets covering entire series, such as the widely available "DB3/DC34/DB4/DB6" datasheets from various manufacturers. The DB2 is often included in this family, with similar construction and application guidelines.

| Parameter | Symbol | Value | Unit | Conditions | |-----------|--------|-------|------|-------------| | | V_BO | 28 – 36 | V | I_BO = 50 µA typical | | Breakover Current | I_BO | 50 – 200 | µA | | | Switching Voltage Symmetry | ΔV_BO | ±3 | V | V_BO positive vs negative | | Peak Output Current | I_PK | 2 | A | t_p = 10 µs | | On-State Voltage | V_AK | ≈ 5 – 8 | V | at I_PK | | Leakage Current | I_R | < 10 | µA | at 0.8 V_BO | | Junction Temperature | T_J | -40 to +125 | °C | |

): Capable of handling significant, short-duration current pulses (typically >2Ais greater than 2 cap A pulse) to trigger a Triac effectively. Rapid switching (often ) ensures the Triac turns on precisely. diac db2 datasheet pdf 14 top

Often color bands or printed "DB2" plus a 2-digit date code. While a standalone DB2 datasheet can be elusive,

A DIAC DB2 is a bidirectional trigger diode designed to turn on (conduct) only when the applied voltage across its terminals exceeds a certain breakover voltage ( VBOcap V sub cap B cap O end-sub

A DIAC (Diode for Alternating Current) is a bidirectional trigger diode that conducts current only after its breakover voltage ( VBOcap V sub cap B cap O end-sub Rapid switching (often ) ensures the Triac turns

The AC voltage charges a capacitor through a potentiometer. Triggering: When the capacitor voltage reaches the VBOcap V sub cap B cap O end-sub of the DB2, the DIAC breaks down and conducts.

The DB2 triggers in both positive and negative AC half-cycles, allowing for symmetrical triggering of Triacs. Low Breakover Voltage ( VBOcap V sub cap B cap O end-sub

Understanding the DB2 DIAC: Comprehensive Datasheet Overview and Top Applications

While the DB2 is a small signal device, it can handle repetitive peak currents of for short durations (10 ms at 50/60 Hz). This is sufficient to trigger most TRIACs in the Z0103, BT136, or BTA series.
