Overview
The Littelfuse SJ6020N2RP is a high-temperature silicon-controlled rectifier (SCR) from the SJxx20xx series, designed for uni-directional switching applications. It features a 600 V rated repetitive off-state voltage and an RMS on-state current of 20 A at a case temperature of 130 °C. The device operates within a junction temperature range of -40 °C to +150 °C. It utilizes a TO-263 (D2-Pak) surface-mount package with a maximum gate trigger current of 10 mA and a peak non-repetitive surge current capability of 300 A at 60 Hz.
Feature Summary
- High thermal endurance with a maximum junction temperature rating of 150 °C
- Sensitive gate design allowing direct interfacing with microprocessors via low trigger currents
- Robust surge handling capabilities up to 300 A for demanding transient conditions
Applications
- Phase control in heating systems
- Motor speed controls
- Capacitive discharge ignition systems for gas engines
- Inrush current controllers
Procurement Notes
Verify the specific ordering suffix 'RP' confirms the reel pack configuration rather than tube packaging. Confirm that the component marking matches the expected YMXXX date code format. Ensure the selected distributor provides traceability documentation consistent with Littelfuse manufacturing standards for this specific thyristor variant.
Selection Notes
Select this component when a surface-mount SCR is required for high-temperature environments exceeding standard ratings. The 10 mA gate sensitivity offers a balance between noise immunity and ease of drive compared to lower sensitivity options. Verify that the PCB layout accommodates the D2-Pak thermal dissipation requirements for the intended RMS current load.
Part Context
This part belongs to the SJxx20xx family of 20 Amp high junction temperature SCRs. The 'N' designation indicates the TO-263 surface-mount package, while '60' specifies the 600 V blocking voltage. The '2' suffix denotes the 10 mA maximum gate trigger current sensitivity level within this product line.
Replacement Considerations
Direct replacements include other SJxx20Nx variants with different voltage or sensitivity ratings, such as SJ4020N2RP. Cross-package alternatives like the SJ6020RATP are available but require through-hole mounting considerations.
