Overview
The Littelfuse S6055NRP is a Silicon Controlled Rectifier (SCR) from the Teccor Sxx55x series, rated for 800 V repetitive off-state voltage and 55 A RMS on-state current. It features a non-isolated TO-263 (SMTO-263-2) surface-mount package with three pins. Key electrical parameters include a maximum gate trigger current of 40 mA, a forward voltage of 1.8 V, and a holding current of 60 mA. The device supports an operating temperature range from -40 °C to +125 °C and offers a surge current capability of 650 A.
Feature Summary
- Surface-mount construction in a compact SMTO-263-2 package for automated PCB assembly
- High voltage blocking capability up to 800 V for robust circuit protection
- Sensitive gate design allowing direct interfacing with low-power control logic
Applications
- Solid-state relays and contactors
- Motor speed control circuits
- Lighting dimmer applications
Procurement Notes
Verify the specific suffix 'NRP' against the manufacturer's official datasheet to confirm the exact packaging configuration and reel specifications. Ensure the selected component matches the required 800 V rating and surface-mount form factor for the target application design.
Selection Notes
Select this component when an 800 V SCR is required in a surface-mount format. Compare the 55 A RMS current rating against the peak load requirements. Verify that the thermal management solution accommodates the 1.8 V forward voltage drop at the expected operating current.
Part Context
This part belongs to the Littelfuse Teccor Sxx55x family of SCRs, which provides standardized ratings for industrial switching. The S6055NRP specifically addresses the need for high-voltage handling in a compact footprint compared to traditional through-hole alternatives.
Replacement Considerations
Cross-reference with other S6055 variants such as S6055R or S6055MTP if through-hole mounting is acceptable. Verify pinout compatibility and thermal resistance differences before substituting with components from other manufacturers.
