Overview
The Central Semiconductor Corp 2N2328 PBFREE is a silicon controlled rectifier (SCR) housed in a TO-39 metal can package. It supports a repetitive peak reverse voltage of 300V and a non-repetitive peak forward voltage of 400V. The device handles an on-state average current of 1.6A with a holding current of 50mA. It features a gate trigger voltage of 1.5V and operates within a junction temperature range of -65°C to 125°C.
Feature Summary
- Robust TO-39 metal can construction for reliable performance
- High surge current capability for transient protection
- Low gate trigger voltage for efficient control
Applications
- Industrial motor control systems
- Power regulation circuits
- Lighting control applications
Procurement Notes
Verify the specific voltage rating variant required, as the 2N2328 series includes multiple options ranging from 25V to 400V. Confirm that the TO-39 through-hole package matches the PCB footprint. Ensure the lead-free designation aligns with environmental compliance standards. Cross-reference datasheet electrical characteristics against circuit requirements before ordering.
Selection Notes
Select this component when a hermetically sealed SCR is needed for high-voltage switching. The TO-39 case offers superior thermal dissipation compared to plastic packages. Consider the 1.6A continuous current limit and 400V surge rating for appropriate margin. Evaluate gate sensitivity requirements against the 1.5V trigger specification.
Part Context
This part belongs to the 2N232x family of SCRs manufactured by Central Semiconductor. The family shares the same TO-39 metal can form factor but varies in voltage ratings. The 2N2328 specifically provides a 300V RMS rating, positioning it between lower-voltage variants like the 2N2324 and higher-voltage options within the series.
Replacement Considerations
Direct substitutes include other manufacturers' TO-39 SCRs with matching 300V/400V ratings and 1.6A current capacity. Verify pinout compatibility and thermal resistance values. Generic replacements must maintain the same hermetic seal properties if used in harsh environments.
