Overview
The Littelfuse SV6020N2QTP is a Silicon Controlled Rectifier (SCR) belonging to the SVxx20xx series. It features a TO-220L package designed for through-hole mounting. The device supports a repetitive peak reverse voltage of 600 V and an average on-state current of 20 A. It withstands a surge current of 300 A. Gate triggering requirements include a maximum gate trigger current of 6 mA and a maximum gate trigger voltage of 1.5 V. The holding current is rated at 22 mA. The component operates within a temperature range from -40°C to 150°C.
Feature Summary
- High thermal stability with a junction temperature rating up to 150°C
- Integrated diac structure for simplified AC phase control applications
- Robust surge current handling capability of 300 A
Applications
- AC motor speed controls
- Temperature modulation systems
- Lighting dimmer circuits
Procurement Notes
Verify the specific suffix QTP against official Littelfuse documentation to confirm lead-free compliance and RoHS status. Confirm the exact pinout configuration for the TO-220L package before integration. Ensure the selected variant matches the required voltage and current ratings for the target circuit design.
Selection Notes
Select this component when designing AC switching circuits requiring integrated gate drive simplicity. The built-in diac eliminates the need for discrete external trigger components. Verify that the 600V blocking voltage and 20A continuous current meet the load requirements. Check thermal management needs given the 150°C operating limit.
Part Context
This SCR is part of the Teccor Quadrac family, which combines a triac and a diac in a single package. This integration reduces assembly time and cost compared to using separate discrete components. The SVxx20xx series provides reliable performance for noise-immune AC control applications.
Replacement Considerations
Check Littelfuse datasheets for other Quadrac devices in the QxxxxLTx series with matching 600V and 20A ratings. Verify pin compatibility and thermal characteristics before substituting.
