The breakover voltage is the absolute threshold at which the DIAC snaps from an off-state (high resistance) to an on-state (low resistance). For the standard DB2 series, this typically ranges between , ensuring crisp triggering when tied to standard AC mains phase-shifting networks. 2. Breakover Voltage Symmetry (
Before applying a DB2 DIAC to a hardware design, certain fundamental criteria from its Alldatasheet Archive profiles must be evaluated: Datasheet - DB3, DB4, SMDB3 - Diac - STMicroelectronics
Based on standard industry DIAC datasheets from manufacturers like STMicroelectronics , here are the typical parameters for this series: Breakover Voltage ( VBOcap V sub cap B cap O end-sub diac db2 datasheet pdf 14 top
The is a surface-mount or through-hole DIAC widely produced by manufacturers like STMicroelectronics, Diotec, and EIC Semiconductor. It is optimized for low-cost, high-volume AC switching applications.
The is a robust, cost-effective trigger device for any AC phase control circuit. By understanding its 14 top parameters —from breakover voltage (32V) to dv/dt immunity (50 V/µs)—you can design dimmers, regulators, and controllers that operate reliably for years. The breakover voltage is the absolute threshold at
, the device triggers into a negative resistance region, causing its internal resistance to drop sharply. This sudden shift permits a fast, high-amplitude current pulse to discharge, making it ideal for gating circuits. Because the device is fully bidirectional, it operates identically during both the positive and negative halves of the AC waveform. 2. Key Electrical Specifications and Datasheet Parameters
The serves as a critical bidirectional trigger component designed primarily for power control systems, phase-angle triggering, and AC voltage modulation. Engineers frequently cross-reference the DB2 DIAC technical specifications to secure stable pulse generation when driving power thyristors and TRIACs.
