DB32

DIACs, SIDACs Overview

The DB32 is a bidirectional silicon trigger diode (DIAC) manufactured by Diotec Semiconductor. It belongs to the DB3 series and features a peak current rating of ±2 A with a maximum power dissipation of 150 mW. The device has a breakover voltage (VBO) range of 32 V to 40 V, with a tolerance (ΔVBO) of 5 V. It operates within a junction temperature range up to 100°C and exhibits a thermal resistance from junction to ambient of less than 300 K/W when leads are maintained at ambient temperature.

DIACs, SIDACs Feature Summary

• Bidirectional switching capability for symmetrical triggering applications
• Protected against fault triggering caused by light exposure
• Compliant with RoHS and REACH environmental standards

DIACs, SIDACs Applications

• Triggering of Triacs and Thyristors
• AC switches and controls
• Dimmer circuits

DIACs, SIDACs Procurement Notes

Verify component authenticity through official Diotec channels or authorized distributors. Confirm datasheet version and compliance status prior to integration. Ensure storage conditions align with commercial grade specifications. Validate lead integrity and package dimensions against mechanical drawings before assembly.

DIACs, SIDACs Selection Notes

Select the DB32 when a specific breakover voltage between 32 V and 40 V is required for AC control circuits. Consider the ±2 A peak current limit and 100°C maximum junction temperature for thermal management. Evaluate the DO-35 axial package constraints for PCB layout and mounting requirements in dimmer or switch designs.

DIACs, SIDACs Part Context

The DB32 is part of the DB3 family of trigger diodes produced by Diotec Semiconductor. This series includes variants such as the DB3, DB31, and DB4, which share similar structural characteristics but differ in breakover voltage ratings. These components are designed for standard commercial and industrial applications requiring reliable phase control.

DIACs, SIDACs Replacement Considerations

Cross-reference with other manufacturers' DIACs offering identical VBO ranges and current ratings. Verify pinout compatibility and package dimensions to ensure direct substitution without circuit modification.
