BRX49 PBFREE

Scrs Overview

The BRX49 PBFREE is a silicon controlled rectifier (SCR) manufactured by Central Semiconductor Corp. It features a standard recovery type designed for through-hole mounting in TO-92-3 packages. The device supports a repetitive peak reverse voltage of 400V and an average on-state current of 0.8A. It operates within a junction temperature range of -40°C to 125°C. The component exhibits a gate trigger voltage of 8.0V and a non-repetitive surge current rating of 10A at 60Hz.

Scrs Feature Summary

• Standard recovery silicon controlled rectifier construction
• Through-hole mounting capability in TO-92-3 package
• Operates within extended industrial temperature ranges

Scrs Applications

• General purpose switching circuits
• Power control applications requiring low current handling
• Industrial equipment protection systems

Scrs Procurement Notes

Verify the specific ordering suffix matches the required lead-free configuration. Confirm that the TO-92-3 package dimensions align with the target PCB layout constraints. Ensure the 400V reverse voltage rating provides sufficient margin for the intended circuit's peak transient conditions. Validate the 0.8A continuous current limit against the maximum load requirements to prevent thermal overstress during operation.

Scrs Selection Notes

Select this component when a standard recovery SCR is required for low-current applications. The TO-92-3 package suits space-constrained designs needing through-hole reliability. Consider the 400V blocking capability for medium-voltage isolation needs. Evaluate the 10A surge rating for potential inrush current scenarios. Ensure the 8.0V gate trigger voltage is compatible with the driving logic levels available in the system design.

Scrs Part Context

This part belongs to the BRX44 series of SCRs from Central Semiconductor, which covers a range of current and voltage ratings. The series utilizes silicon technology for robust performance. The BRX49 specifically addresses the lower end of the current spectrum within this family. It shares common packaging standards with other members of the series for consistent manufacturing processes.

Scrs Replacement Considerations

Cross-reference with BRX44 series variants if different current or voltage ratings are needed. Verify pinout compatibility before substituting with other TO-92-3 SCRs. Check datasheets for equivalent gate trigger characteristics to ensure functional interchangeability.
