Overview
The SV6020R1QTP is a sensitive gate Silicon Controlled Rectifier (SCR) from the Littelfuse SV series, rated for 600 V repetitive peak off-state voltage and 20 A RMS on-state current. It features a maximum average on-state current of 12.8 A and a non-repetitive surge current capability of 225 A at 50 Hz or 300 A at 60 Hz. The device operates within a junction temperature range of -40°C to 150°C, with a maximum gate trigger voltage of 1.5 V and gate trigger current of 6 mA. Packaged in a TO-220AB through-hole configuration, it ensures reliable performance in high-temperature environments.
Feature Summary
- Sensitive gate design for low-power triggering applications
- High junction temperature tolerance up to 150°C for stable operation
- Through-hole TO-220AB package for robust mechanical mounting
Applications
- Industrial motor control systems
- Power supply regulation circuits
- General purpose rectification in high-temperature environments
Procurement Notes
Verify component authenticity by checking manufacturer markings against official datasheet specifications. Confirm RoHS compliance status as indicated in product documentation. Ensure the TO-220AB package variant matches system requirements. Cross-reference part numbers with authorized distributor lists to avoid counterfeit sources. Validate thermal management capabilities align with application constraints before procurement.
Selection Notes
Select this SCR for applications requiring high-temperature stability and sensitive gate triggering. The 600 V rating suits medium-voltage AC control tasks. Consider the 20 A RMS current capacity for load requirements. The TO-220AB package facilitates easy integration into existing through-hole designs. Evaluate thermal dissipation needs given the 150°C junction limit.
Part Context
Part of the Littelfuse SV series, designed for general-purpose thyristor applications. The SV6020R1QTP specifically targets high-temperature environments where standard components may fail. It complements other SCRs in the family offering different voltage or current ratings while maintaining consistent package and performance characteristics.
Replacement Considerations
Direct substitutes include SV6020L1TP within the same series. Verify voltage and current ratings match exactly. Check package compatibility for direct replacement. Ensure gate trigger parameters are compatible with existing drive circuits.
