BR100-04LLD

Overview

The BR100-04LLD is a surface mount bidirectional silicon trigger diode (DIAC) manufactured by Diotec Semiconductor. It features a peak current rating of ±2 A and a maximum power dissipation of 150 mW. The device has a breakover voltage (VBO) of 40 V with a tolerance range (ΔVBO) of 5 V. It operates within a junction temperature range up to 125°C. Thermal resistance from junction to ambient is typically 150 K/W, while junction-to-terminal resistance is 70 K/W.

Feature Summary

• Bidirectional switching capability for AC control applications
• Protected against fault triggering caused by light exposure
• Compliant with RoHS and REACH directives

Applications

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

Procurement Notes

Verify the specific part number suffix LLD to confirm the surface mount package type and lead-free compliance status. Ensure that the sourcing channel provides official documentation confirming the component meets the stated thermal and electrical specifications. Cross-reference the manufacturer's latest datasheet to validate any recent updates to mechanical dimensions or material composition before finalizing procurement orders.

Selection Notes

Select this component when a bidirectional trigger diode with a 40 V breakover voltage is required for surface mount assembly. Confirm that the application circuit can handle the specified ±2 A peak current without exceeding the 150 mW power dissipation limit. Verify that the operating environment remains within the 125°C maximum junction temperature constraint to ensure reliable long-term performance in standard commercial or industrial settings.

Part Context

This component belongs to the BR100 series of SMD Trigger-Diodes produced by Diotec Semiconductor. It serves as a specialized semiconductor switch designed primarily for phase control applications. The device is engineered to provide consistent triggering characteristics for thyristor-based circuits, distinguishing itself through its compact surface mount form factor and robust protection against environmental interference such as light-induced faults.

Replacement Considerations

Consult the manufacturer's official cross-reference list for verified substitutes. Generic DIAC replacements must match the 40 V breakover voltage and ±2 A peak current ratings. Ensure any alternative component supports surface mount technology and maintains similar thermal resistance values to prevent overheating in existing PCB layouts.
