Overview
The Littelfuse SV6020N1QTP is a Silicon Controlled Rectifier (SCR) belonging to the SVxx20xx series, manufactured by Littelfuse. It features a TO-220L package with through-hole mounting and supports an average on-state current of 20 A. The device has a rated repetitive peak off-state voltage of 600 V and a non-repetitive surge current rating of 300 A. Key electrical parameters include a maximum gate trigger current of 6 mA, a forward voltage of 1.6 V, and a holding current of 22 mA. It operates within a temperature range of -40°C to +150°C.
Feature Summary
- High thermal stability with a maximum junction temperature of 150°C
- Robust surge handling capability for transient overcurrent events
- Low gate sensitivity for efficient triggering control
Applications
- Industrial motor control systems
- AC power switching applications
- General purpose rectification circuits
Procurement Notes
Verify the specific ordering suffix QTP against official Littelfuse documentation to confirm package variant and compliance status. Ensure the procurement channel provides valid traceability for the component lot. Cross-reference the manufacturer part number with authorized distributor listings to avoid counterfeit products. Confirm that the requested quantity aligns with standard factory packaging requirements.
Selection Notes
Select this SCR for designs requiring 600 V blocking voltage and 20 A continuous current in a TO-220L form factor. Evaluate the 6 mA gate trigger current against the driving circuit capabilities to ensure reliable turn-on. Consider the 300 A surge rating when sizing protection for inductive loads or startup transients. Verify thermal management strategies to maintain junction temperatures below the 150°C limit during operation.
Part Context
This component is part of the SVxx20xx family of SCRs from Littelfuse, designed for general-purpose power control. The SV6020N1QTP specifically utilizes the TO-220L package, distinguishing it from surface-mount variants like the SJ6020N1TP. It shares core electrical characteristics with other members of the 20A/600V class but differs in physical mounting and pin configuration.
Replacement Considerations
Direct substitutes may include the SV6020L1TP from the same manufacturer family. Verify compatibility regarding package dimensions, pinout, and thermal resistance before substitution.
