The DB2 is commonly supplied in a DO-35 or DO-214 (SMD) glass package, ensuring robust, high-temperature operation. 3. Working Principle
If you are looking for the actual technical data, the (often cross-referenced with the TMMDB3 ) is typically manufactured by STMicroelectronics or other semiconductor firms. Key specs include: VBO (Breakover Voltage): Typically 28V to 36V.
): The range of internal temperatures the diode can safely operate at, commonly -40 to +125°C. The safe temperature range for storing the component. C. Physical and Packaging Data
| Parameter | Typical Value (DB2/DB3) | |-----------|--------------------------| | | 28–36 V (most common) If "14" means 14V, check DB2-14 variant | | Breakover Current (IBO) | ≤ 50 µA | | On-State Voltage | ~3–5 V | | Peak Pulse Current | 2 A (max) | | Power Dissipation | 150–300 mW | | Operating Temp | -40°C to +125°C | | Package | DO-35 (glass axial), SOT-23, or SOD-123 |
The diac ceases to conduct once the current drops below the holding current ( IHcap I sub cap H 4. Primary Applications: Where to Use the DB2
