Overview
The Littelfuse SRR6012D1RP is a standard Silicon Controlled Rectifier (SCR) from the Teccor SRR60 series, designed for phase control and general switching applications. It features a DPAK-2 (TO-252-2) surface-mount package with glass-passivated junctions. Key electrical parameters include a rated repetitive off-state voltage (VDRM) of 600 V and an RMS on-state current (IT(RMS)) of 12 A. The device supports a non-repetitive surge current up to 120 A and has a maximum gate trigger current (IGT) of 6 mA. Operating temperature ranges from -40°C to +125°C, with a holding current maximum of 50 mA and off-state leakage current of 10 µA.
Feature Summary
- Sensitive gate design allows triggering with low microampere currents from sense coils or microprocessors.
- Glass-passivated junctions provide robust protection against voltage transients and environmental stress.
- Standard phase control characteristics enable reliable operation in AC power regulation circuits.
Applications
- Phase control circuits for heating elements and industrial heaters.
- Motor speed control systems for universal and induction motors.
- Capacitive discharge ignition (CDI) systems.
- General purpose rectifiers and DC motor controls.
Procurement Notes
Verify component authenticity by checking the manufacturer's marking code against official datasheet specifications. Confirm RoHS compliance status through the latest environmental declaration documents provided by Littelfuse. Ensure the ordering suffix matches the required reel packaging quantity for automated assembly processes.
Selection Notes
Select this SCR for applications requiring 600 V blocking capability and 12 A continuous current handling in a compact surface-mount form factor. Consider the 6 mA gate trigger requirement when designing drive circuits to ensure sufficient sensitivity without excessive noise susceptibility compared to higher-power variants.
Part Context
The SRR6012D1RP belongs to the Teccor SRR60 series of standard SCRs manufactured by Littelfuse. This series is engineered for high reliability in power electronics, offering a balance of current capacity and thermal performance suitable for consumer and industrial equipment where space constraints favor surface-mount technologies over through-hole alternatives.
Replacement Considerations
Direct pin-compatible replacements within the same package may include other 12 A, 600 V SCRs in TO-252 packages from Littelfuse or competitors, provided gate trigger characteristics and thermal resistance values are compatible with the existing circuit design constraints.
