Overview
The Central Semiconductor Corp 2N2329 TIN/LEAD is a silicon-controlled rectifier (SCR) manufactured in the TO-92-3 through-hole package. It features a rated repetitive peak off-state voltage of 400V and an RMS on-state current of 1.5A. The device operates within a junction temperature range of -40°C to +125°C. Key electrical characteristics include a gate trigger voltage of 800mV, a gate trigger current of 200µA, and a holding current maximum of 5mA. The component exhibits a forward voltage drop of 1.7V and a non-repetitive peak on-state current capacity of 15A.
Feature Summary
- Utilizes a standard TO-92-3 three-pin axial leaded configuration for through-hole mounting.
- Designed for reliable switching applications with defined gate triggering thresholds.
- Constructed from silicon material suitable for industrial operating temperatures.
Applications
- Lighting control circuits requiring low-power gate triggering.
- Motor speed control systems utilizing phase-angle firing techniques.
- General-purpose thyristor switching in consumer electronics.
Procurement Notes
Verify the specific ordering suffix required for tin/lead plating when placing orders. Confirm RoHS compliance status as tin/lead variants may differ from lead-free equivalents. Ensure the supplier provides the official datasheet for the exact part number variant to validate electrical parameters before integration into design specifications.
Selection Notes
Select this component when a low-current SCR with a 400V blocking capability is required for through-hole assemblies. Compare the 1.5A RMS rating against load requirements to ensure adequate thermal headroom. Evaluate the gate sensitivity parameters against the driving circuit's output capabilities to guarantee reliable turn-on under all operating conditions.
Part Context
This part belongs to the MCR22 series of SCRs produced by Central Semiconductor. It shares similar form factors and basic electrical profiles with other devices in the MCR22 family, such as the MCR22-6, which offers comparable voltage and current ratings in the same TO-92 package style.
Replacement Considerations
The MCR22-6 is a confirmed substitute within the same product family offering identical voltage and current ratings in a TO-92 package. Verify pinout compatibility and thermal characteristics before substituting other generic 400V SCRs.
