Overview
The SJ4016R2TP is a Silicon Controlled Rectifier (SCR) manufactured by Littelfuse, designed for high-power switching applications. It features a rated repetitive off-state voltage of 400 V and an on-state RMS current of 16 A. The device operates within a temperature range of -40°C to +150°C and utilizes a TO-220-2 through-hole package. Key electrical characteristics include a forward voltage of 1.6 V, a gate trigger voltage of 1.5 V, and a gate trigger current of 10 mA. The non-repetitive peak on-state current is specified at 225 A, with a maximum holding current of 35 mA.
Feature Summary
- High thermal stability enabling operation up to 150°C junction temperature
- Robust surge current handling capability for inductive load protection
- Low forward voltage drop for improved power efficiency
Applications
- Industrial motor control circuits
- AC power regulation systems
- Battery charging equipment
Procurement Notes
Verify the specific suffix 'R2' against the official Littelfuse datasheet to confirm pinout orientation and thermal pad configuration. Ensure the procurement channel provides valid traceability documentation. Confirm that the component meets RoHS and REACH compliance standards required for the target assembly process before finalizing orders.
Selection Notes
Select this component when a 400V blocking voltage and 16A continuous current rating are required in a TO-220-2 package. Compare the 10mA gate trigger current against driver capabilities to ensure reliable turn-on. Evaluate the 225A surge rating against potential inrush currents in the specific application circuit to prevent device failure during startup conditions.
Part Context
This part belongs to the SJxx16xx series of thyristors from Littelfuse. The series is characterized by standard SCR configurations suitable for general-purpose power control. The TO-220-2 package facilitates easy mounting onto heat sinks for thermal management in medium-power industrial environments.
Replacement Considerations
Cross-reference with other Littelfuse SJ4016 variants or equivalent 400V/16A SCRs from other manufacturers. Verify that any substitute matches the TO-220-2 footprint and maintains identical gate trigger specifications to avoid redesigning the drive circuitry.
