Overview
The Littelfuse S4010LTP is a silicon-controlled rectifier (SCR) rated for 400V repetitive peak off-state voltage and 10A RMS on-state current. It utilizes a low-gate sensitivity design with a maximum gate trigger current of 500µA, facilitating efficient control circuitry. The device is housed in an isolated TO-220AB package, supporting flange mounting for effective thermal dissipation. It operates within a junction temperature range of -40°C to +110°C and features a non-repetitive surge current capability of 100A.
Feature Summary
- Low gate sensitivity requiring minimal trigger current for reliable activation
- Isolated case construction enabling direct mounting to heatsinks without additional insulation
- High surge current handling capacity for robust transient protection
Applications
- General purpose AC power control circuits
- Lighting dimmer applications
- Solid state relay designs
Procurement Notes
Verify the specific suffix against manufacturer documentation to confirm exact electrical tolerances and packaging variations. Ensure compatibility with existing thermal management solutions given the TO-220AB form factor. Cross-reference datasheet parameters for gate characteristics to validate interface requirements before integration into final assemblies.
Selection Notes
Select this component when a standard 10A SCR with moderate voltage blocking is required. The low gate sensitivity reduces drive power needs compared to higher sensitivity alternatives. Consider the TO-220AB package size for board space constraints and verify that the 400V rating aligns with the system's peak line voltages and transient requirements.
Part Context
This part belongs to the S4010 series of general-purpose SCRs from Littelfuse. The series offers various voltage ratings and package options to suit different power control needs. The S4010LTP specifically targets applications requiring reliable switching at 400V with simplified gate drive capabilities.
Replacement Considerations
Direct replacements must match the 400V/10A rating and TO-220AB package. Verify gate trigger current specifications to ensure compatible driver circuits. Check pinout configurations to prevent installation errors during retrofitting or substitution.
