Overview
The Littelfuse SV6012R2QTP is a high junction temperature Silicon Controlled Rectifier (SCR) from the SVxx12xxQ series, rated for 600 V repetitive peak reverse voltage and 12 A RMS on-state current. It utilizes a TO-220AB non-isolated package with a maximum junction temperature of 150°C. The device features a sensitive gate trigger level with a maximum IGT of 10 mA at approximately 1.5 V. It supports a peak non-repetitive surge current of 180 A at 60 Hz and offers high dv/dt performance of 800 V/µs minimum at 125°C. The component is RoHS compliant and recognized to UL 1557.
Feature Summary
- High junction temperature capability up to 150°C for demanding thermal environments
- Sensitive gate trigger characteristics requiring low current for reliable activation
- High dv/dt performance ensuring stability against rapid voltage transients
- Internally constructed isolated packages available for ease of heat sinking
Applications
- AC Generator (ACG) rectifiers
- Battery voltage regulators
- Generic converters and inrush current controllers in AC to DC applications
- Controls for power tools and home appliances
Procurement Notes
Verify the specific ordering suffix to confirm the package type and gate sensitivity. The 'R' designation indicates a TO-220AB non-isolated mounting tab configuration, while '2' specifies the 10 mA gate trigger sensitivity. Confirm compliance requirements such as RoHS status and UL recognition before finalizing procurement specifications.
Selection Notes
Select this component when an application requires a 12 A SCR with a 600 V blocking voltage and operation up to 150°C junction temperature. Ensure the circuit design accommodates the 10 mA maximum gate trigger current and provides adequate heat sinking to maintain case temperatures within limits defined by the RMS current derating curves.
Part Context
This part belongs to the SVxx12xxQ series of 12 Amp High Junction Temperature SCRs manufactured by Littelfuse. The series includes variants with different package types (TO-220L, TO-220R, TO-263) and gate sensitivities (6 mA or 10 mA). The Q suffix denotes a low turn-off time rating compared to standard versions.
Replacement Considerations
Direct substitutes within the same series include SV6012L2QTP (isolated TO-220L package) and SV6012N2QTP (surface mount TO-263 package). Verify that any replacement maintains the required 600 V rating, 12 A current capacity, and compatible gate trigger parameters.
