Overview
The S4010V is a non-sensitive gate Silicon Controlled Rectifier (SCR) manufactured by Littelfuse Inc. It features a 400 V off-state voltage rating and a 10 A average on-state current capability. The device utilizes a TO-251AA surface mount package, ensuring compact integration into printed circuit boards. Its maximum gate trigger voltage is specified at 1.5 V, facilitating reliable triggering within low-power control circuits.
Feature Summary
- Non-sensitive gate design for robust triggering performance
- Surface mount construction in a TO-251AA package
- Uni-directional switching capability for phase control applications
Applications
- Phase control circuits
- Heating element regulation
- Motor speed controls
Procurement Notes
Verify the specific ordering suffix to confirm the exact packaging configuration, as variations exist between tube and bulk formats. Ensure the component meets RoHS compliance requirements if mandated by the target assembly standards. Cross-reference the manufacturer's latest datasheet to validate pinout compatibility and thermal resistance specifications against the intended PCB layout constraints.
Selection Notes
Select this component when a surface mount SCR with moderate current handling is required for uni-directional AC switching. The non-sensitive gate characteristic simplifies drive circuit design compared to sensitive gate variants. Consider the TO-251AA footprint for space-constrained designs where through-hole mounting is not feasible. Evaluate thermal management needs based on the 10 A current rating and ambient operating conditions.
Part Context
This part belongs to the Sxx10x series of low power SCRs from Littelfuse, designed for general-purpose switching up to 1200 V ratings. The series supports various voltage grades, with the S4010V specifically addressing the 400 V requirement. It serves as a solid-state alternative to mechanical relays in applications requiring fast switching and high reliability without moving parts.
Replacement Considerations
Consult official Littelfuse substitution guides for direct equivalents. Generic replacements may differ in gate sensitivity or thermal characteristics. Verify that any substitute maintains the TO-251AA package dimensions and electrical ratings to ensure board compatibility.
