Overview
The 2N2329 PBFREE is a silicon-controlled rectifier (SCR) manufactured by Central Semiconductor Corp. It features a TO-18 metal can package and operates in a bulk configuration. The device supports a maximum repetitive peak reverse voltage of 400 V and a holding current of 5 mA. Gate trigger characteristics include a maximum gate trigger voltage of 1.5 V and a maximum gate trigger current of 50 mA. The component handles a maximum average forward on-state current of 1 A with a non-repetitive peak surge current capacity of 15 A. It functions within a junction temperature range of -65°C to +175°C.
Feature Summary
- Utilizes a hermetically sealed TO-18 metal can construction for robust environmental protection.
- Designed for high-voltage switching applications with a 400 V blocking capability.
- Features low gate trigger requirements suitable for standard logic interface circuits.
Applications
- High-voltage DC switching circuits
- Phase control systems
- Solid-state relay inputs
Procurement Notes
Verify the specific datasheet revision for the 2N2329 PBFREE before integration, as electrical tolerances may vary between manufacturing lots. Confirm that the TO-18 mounting style aligns with the target PCB or chassis design constraints. Ensure thermal management strategies account for the specified power dissipation limits during continuous operation to maintain reliability within the stated temperature range.
Selection Notes
Select this component when a hermetically sealed SCR is required for high-voltage DC applications. The TO-18 package suits through-hole mounting where space allows. Compare the 5 mA holding current against load requirements to prevent unintended turn-off. Verify that the 1 A average current rating exceeds the circuit's steady-state demands while accounting for ambient temperature derating factors.
Part Context
The 2N2329 belongs to the standard silicon-controlled rectifier family produced by Central Semiconductor. It serves as a discrete power semiconductor device for controlling electrical energy. The PBFREE suffix indicates compliance with lead-free manufacturing standards. This part number represents a specific variant within the broader thyristor product line designed for industrial and commercial switching duties.
Replacement Considerations
Cross-reference with other TO-18 SCRs offering similar 400 V and 1 A ratings. Verify pinout compatibility and thermal resistance values before substitution. Ensure alternative devices meet the same gate trigger specifications to maintain circuit performance without redesign.
