S8010DRP

Overview

The S8010DRP is a silicon-controlled rectifier (SCR) manufactured by Littelfuse, rated for an RMS on-state current of 8 A and a repetitive peak off-state voltage of 1000 V. It is housed in a DPAK-2 (TO-252-2) surface-mount package designed for automated PCB assembly. The device features a maximum gate trigger current of 15 mA and a gate trigger voltage of 1.5 V, enabling sensitive triggering from microprocessor interfaces. It operates within a temperature range of -40°C to +125°C and exhibits a forward voltage drop of 1.6 V at full load. The component supports non-repetitive surge currents up to 100 A and maintains a holding current of 30 mA.

Feature Summary

• Sensitive gate structure allows direct interfacing with low-power control logic
• Surface-mount DPAK-2 package facilitates high-density PCB integration
• High thermal stability supports operation in demanding industrial environments

Applications

• Solid-state relays requiring compact switching solutions
• General-purpose AC power control circuits
• Industrial motor speed control systems

Procurement Notes

Verify the specific ordering suffix against the manufacturer's latest datasheet to confirm pinout compatibility and packaging type. Ensure that the selected variant matches the required voltage and current ratings for the target application. Cross-reference the RoHS compliance status with current regulatory requirements before finalizing procurement orders.

Selection Notes

Select this component when a robust 1000 V blocking capability is required in a surface-mount form factor. Compare the 8 A RMS rating against the circuit's continuous load requirements to ensure adequate margin. Evaluate the thermal resistance of the DPAK-2 package relative to the expected heat dissipation in the final enclosure design.

Part Context

This part belongs to the Sxx08x series of thyristors from Littelfuse, which are engineered for reliable switching in moderate-power applications. The S8010DRP specifically addresses the need for high-voltage isolation in compact electronic designs, serving as a discrete alternative to larger module-based solutions.

Replacement Considerations

Direct replacements include other 8 A, 1000 V SCRs in TO-252 packages from Littelfuse or compatible manufacturers. Verify that substitute parts maintain identical gate trigger characteristics and thermal performance specifications.
