C103YY TIN/LEAD

Scrs Overview

The C103YY is an epoxy molded silicon controlled rectifier (SCR) from the Central Semiconductor C103 series, designed for control systems and sensing circuit applications. It features a through-hole TO-92-3 package with tin/lead termination. Key electrical parameters include a maximum holding current of 5 mA, a non-repetitive on-state current of 8 A, a repetitive peak off-state voltage of 60 V, and a root mean square on-state current of 0.8 A.

Scrs Feature Summary

• Epoxy molded construction for durability in control systems
• Silicon controlled rectifier architecture for sensing circuits
• Through-hole mounting capability via TO-92-3 package

Scrs Applications

• Control systems
• Sensing circuits

Scrs Procurement Notes

Verify that the specific order matches the C103YY designation with tin/lead terminations, distinct from lead-free variants. Confirm the TO-92-3 package type and electrical ratings against the official datasheet to ensure compatibility with the target application requirements before purchase.

Scrs Selection Notes

Select this component when a low-voltage SCR with a standard through-hole footprint is required for sensing or control logic. The 60 V rating limits suitability to low-power applications. Ensure the design accommodates the 5 mA holding current threshold and the 8 A surge capability during turn-on events.

Scrs Part Context

This part belongs to the Central Semiconductor C103 series of silicon controlled rectifiers. The series includes variants with different voltage ratings, such as the C103A and C103B, which offer higher blocking voltages. The C103YY specifically denotes the 60 V version with tin/lead leads.

Scrs Replacement Considerations

Direct substitutes within the same series include the C103A and C103B, though these offer higher voltage ratings. Verify pinout compatibility and thermal characteristics when cross-referencing with other manufacturers' TO-92 SCRs.
