2N881 PBFREE

Scrs Overview

The Central Semiconductor Corp 2N881 PBFREE is a silicon-controlled rectifier (SCR) designed for through-hole mounting in the TO-18 package. It features a repetitive peak reverse voltage of 200V and an on-state current of 0.8A. The device supports gate trigger currents as low as 0.8mA and offers high surge capability with an IFSM rating of 15A. Operating within a junction temperature range of -65°C to +175°C, it provides reliable performance for power control applications requiring robust switching characteristics.

Scrs Feature Summary

• Utilizes a hermetically sealed TO-18 metal case for enhanced environmental protection and thermal stability
• Features low gate trigger current requirements to facilitate efficient drive circuit integration
• Provides high non-repetitive surge current capacity for handling transient load conditions

Scrs Applications

• High-voltage DC motor speed control systems
• Industrial power regulation circuits
• Solid-state relay output stages

Scrs Procurement Notes

Verify that the specific order includes the PBFREE suffix to ensure compliance with RoHS directives and lead-free manufacturing standards. Confirm the TO-18 package dimensions match your PCB layout constraints. Check datasheet specifications for gate trigger parameters to ensure compatibility with your driving logic levels before finalizing procurement.

Scrs Selection Notes

Select this component when a ruggedized, hermetically sealed SCR is required for high-temperature environments up to 175°C. The TO-18 package offers superior heat dissipation compared to plastic equivalents. Ensure the 200V blocking voltage meets your circuit's peak reverse voltage requirements and that the 0.8A RMS current rating aligns with continuous load demands.

Scrs Part Context

This part belongs to the Central Semiconductor thyristor family, specifically engineered for industrial-grade reliability. The 2N881 designation indicates a standard silicon-controlled rectifier configuration. The PBFREE suffix denotes a lead-free finish compliant with international environmental regulations, distinguishing it from older legacy versions.

Scrs Replacement Considerations

Direct substitutes must maintain the TO-18 package and 200V/0.8A ratings. Verify equivalent gate trigger current specifications to ensure proper circuit operation without modification.
