Diac Db2 Datasheet Pdf 14 Top

A DIAC (Diode for Alternating Current) behaves similarly to a bidirectional neon lamp, triggering conduction only after its threshold limits are crossed. Below are the primary parameters extracted from official technical documentation like the STMicroelectronics DIAC Datasheet to help you accurately size your components: 1. Breakover Voltage ( VBOcap V sub cap B cap O end-sub

): Typically ranges from (for DB3-style performance often associated with DB2 markings). Repetitive Peak On-State Current ( ITRMcap I sub cap T cap R cap M end-sub ): Up to 2.0 A for short pulses ( ). Breakover Current ( IBOcap I sub cap B cap O end-sub ): Maximum 50 A to 100 A . Operating Junction Temperature ( Tjcap T sub j ): -40∘Cnegative 40 raised to the composed with power C to +125∘Cpositive 125 raised to the composed with power C . Power Dissipation ( ): Approximately 150 mW at an ambient temperature of 65∘C65 raised to the composed with power C .

Since DB2 is often grouped with the DB3/DB4 series in manufacturer catalogs, the following specifications are the standard for this class of bidirectional trigger diodes: DIAC DB2 DIODE Datasheet(PDF) - ALLDATASHEET.COM

While the standard DB3 triggers at ~32V, the is designed for lower-voltage triggering . DB2 DIAC datasheets A DIAC (Diode for Alternating Current) behaves similarly

Before we zoom in on the specific DB2 model, it's crucial to understand the fundamentals. DIAC stands for . It is a two-terminal, bidirectional semiconductor switch that only conducts electrical current after its breakover voltage (VBO) has been exceeded.

This is the non-repetitive, one-off surge current the DIAC can withstand. While general DIACs can be rated for higher, the DB series is commonly rated for a , making it suitable for low to medium-power applications like dimmers and motor controllers. Repetitive Peak On-State Current ( ITRMcap I sub

To provide the critical electrical and physical specifications of the (bidirectional trigger diode), typically used in TRIAC phase control circuits. This report addresses the common request for a "datasheet PDF" and explains the "14 top" marking.

The DB2 is a specific type of DIAC, widely recognized in the electronics industry. It is a designed to assist in the even triggering of TRIACs, making it a critical component in AC power control circuits.
