Overview
The Littelfuse SJ6020N2TP is a high junction temperature Silicon Controlled Rectifier (SCR) rated for 600V repetitive peak reverse voltage and 20A RMS on-state current. It utilizes a TO-263AB (D2-Pak) surface-mount package with a maximum junction temperature of 150°C. The device features a gate trigger current of 10mA at approximately 1.5V, enabling efficient control in uni-directional switching applications. It supports surge currents up to 300A at 60Hz half-cycle and includes internal isolation for ease of heat sinking.
Feature Summary
- High thermal capability with a maximum junction temperature of 150°C
- Low gate sensitivity requiring only 10mA trigger current
- Internally constructed isolated package design for improved heat dissipation
- Halogen-free and RoHS compliant construction
Applications
- Phase control in heating systems
- Motor speed controls
- Converters and rectifiers
- Inrush current controllers
- Capacitive discharge systems for gas engine ignition
Procurement Notes
Verify the specific ordering suffix 'RP' indicates reel packaging rather than tube packaging when sourcing components. Confirm that the 10mA gate sensitivity matches the circuit requirements, as other sensitivities exist within the series. Ensure the TO-263 footprint aligns with the PCB layout specifications before finalizing procurement orders.
Selection Notes
Select this component for designs requiring surface-mount installation with high thermal tolerance. The 600V rating suits medium-voltage AC applications, while the 20A RMS current handles moderate power loads. Consider the 10mA gate drive requirement against available driver capabilities, and ensure adequate heatsinking to maintain junction temperatures below the 150°C limit during continuous operation.
Part Context
This part belongs to the SJxx20xx series of 20 Amp High Junction Temperature SCRs from Littelfuse. The series offers various voltage ratings (400V/600V), gate sensitivities (6mA, 10mA, 35mA), and packages (TO-220L, TO-220R, TO-263). The SJ6020N2TP specifically combines the 600V rating, 10mA sensitivity, and TO-263 surface-mount form factor.
Replacement Considerations
Direct replacements include SJ6020N1TP (6mA sensitivity) or SJ6020NATP (35mA sensitivity) if gate drive levels differ. For non-isolated TO-220R packages, consider SJ6020R2TP. Verify pinout compatibility and thermal resistance differences when substituting across package types.
