Overview
The Littelfuse S4010FS21 is a sensitive silicon-controlled rectifier (SCR) with a 10 A on-state current rating and a 400 V repetitive peak off-state voltage. It utilizes an electrically isolated TO-220 package, allowing the mounting tab to be grounded without affecting circuit operation. The device features glass-passivated junctions for parameter stability and includes a maximum DC gate trigger current of 200 µA. Electrical isolation from leads to the mounting tab withstands a minimum high potential test of 2500 V ac rms.
Feature Summary
- Electrically isolated TO-220 package
- Glass-passivated junctions
- High surge capability
Applications
- Half-wave unidirectional gate-controlled rectification
- Low-cost assembly applications requiring electrical isolation
- Convenient packaging techniques for power control circuits
Procurement Notes
Verify the specific ordering suffix against official Littelfuse documentation to confirm package type and isolation ratings. Confirm RoHS compliance status through the manufacturer's current product change notifications or environmental files before finalizing procurement specifications.
Selection Notes
Select this component when a 10 A SCR requires electrical isolation between the case and the circuit ground. Ensure the application operates within the specified -40 °C to +110 °C temperature range. Verify that the required gate sensitivity aligns with the 200 µA maximum DC gate trigger current specification.
Part Context
