Overview
The Littelfuse SV6020L1TP is a 20 Amp high junction temperature Silicon Controlled Rectifier (SCR) from the SVxx20xx series. It features a 600 V repetitive peak reverse voltage and operates with a maximum junction temperature of 150 °C. The device utilizes a TO-220L isolated package for ease of heat sinking. Key electrical parameters include a maximum RMS on-state current of 20 A, a surge current rating of 300 A at 60 Hz half cycle, and a low gate trigger current of 6 mA maximum. It offers high dv/dt performance of 400 V/μs minimum at 125 °C.
Feature Summary
- Halogen-free and RoHS compliant construction
- High junction temperature capability up to 150 °C
- Electrically isolated semiconductor device recognized by UL
- Low gate trigger current sensitivity
Applications
- AC Generator (ACG) rectifiers
- Battery voltage regulators
- Generic AC to DC converters
- Inrush current controllers
- Power tool controls
Procurement Notes
Verify component authenticity through authorized Littelfuse distributors or direct manufacturer channels. Confirm that the ordering suffix 'TP' corresponds to tube packaging containing 50 units per base quantity. Ensure the specific part number matches the required voltage and gate sensitivity ratings before procurement.
Selection Notes
Select this component when applications require high junction temperature operation up to 150 °C and electrically isolated mounting. The TO-220L package provides isolation between the mounting tab and internal circuitry. Verify that the 6 mA gate trigger requirement aligns with the control circuit design capabilities.
Part Context
This SCR belongs to the SVxx20xx series, which includes variants with different voltage ratings, gate sensitivities, and package types such as TO-220R and TO-263. The SV6020L1TP specifically denotes the 600V rating, 6mA gate sensitivity, and TO-220L isolated package configuration within this product family.
Replacement Considerations
Direct replacements within the same series include SV6020R1TP (non-isolated TO-220R) and SV6020N1TP (surface mount TO-263). Cross-series substitution requires verification of thermal resistance, package dimensions, and electrical characteristics against original design specifications.
FAQ
What is the maximum allowable case temperature for the SV6020L1TP at full rated current?
The maximum allowable case temperature is 105 °C when conducting the full 20 A RMS on-state current.
Does the SV6020L1TP package provide electrical isolation?
Yes, the TO-220L package is internally constructed as an electrically isolated semiconductor device, allowing the mounting tab to be connected to a heatsink without shorting the anode.
What is the critical rate of rise of on-state current (di/dt) for this device?
The critical rate of rise of on-state current is 125 A/μs at a frequency of 60 Hz and a junction temperature of 150 °C.
