Overview
The Littelfuse SJ6032LTP is a 32 Amp standard high temperature Silicon Controlled Rectifier (SCR) in the TO-220L isolated package. It features a 600 V repetitive peak off-state voltage and a 40 mA maximum gate trigger current. The device supports an RMS on-state current of 32 A at a case temperature of 80°C, with an average on-state current rating of 20 A under the same conditions. Peak non-repetitive surge current capability reaches 380 A at 60 Hz for a single half-cycle. Thermal resistance from junction to case is specified at 1.9 °C/W.
Feature Summary
- High junction temperature operation up to 150°C
- Isolated mounting tab design for ease of heat sinking
- Low gate current trigger levels for efficient control
Applications
- Phase control in heating systems
- Motor speed controls
- AC rectifiers and voltage regulators
- Industrial power tools and commercial appliances
Procurement Notes
Verify the specific ordering suffix against the manufacturer's official datasheet to confirm the exact package type and packing quantity. Confirm that the component meets RoHS compliance and halogen-free requirements for your assembly process. Ensure thermal management designs account for the specified junction-to-case thermal resistance values during operation.
Selection Notes
Select this component for uni-directional switching applications requiring high temperature stability. The TO-220L package provides electrical isolation between the mounting tab and the cathode, simplifying heatsink integration. Verify that the circuit's peak voltage does not exceed the 700 V non-repetitive blocking limit and that surge currents remain within the rated I2t capabilities.
Part Context
This part belongs to the SJxx32xx series of 32 Amp standard high temperature SCRs manufactured by Littelfuse. The series includes variants with different voltage ratings (400V or 600V), gate sensitivities (15mA or 40mA), and package options including TO-220R, TO-220L, and TO-263.
Replacement Considerations
Consult the official Littelfuse datasheet for cross-reference information. Potential substitutes may include other 32A, 600V SCRs in TO-220 packages with comparable thermal and electrical ratings, provided they meet the specific isolation and trigger current requirements.
