Overview
The Littelfuse SJ4016N1TP is a Silicon Controlled Rectifier (SCR) from the SJxx16xx series, designed for high-power AC switching applications. It features a rated repetitive off-state voltage (VDRM) of 400 V and an on-state RMS current (ItRMS) of 16 A. The device exhibits a forward voltage drop (Vf) of 1.6 V at rated current. Gate triggering requirements include a maximum gate trigger voltage (Vgt) of 1.5 V and a gate trigger current (Igt) of 30 mA. The component operates within a temperature range of -40°C to +150°C and utilizes a TO-220-2 through-hole package.
Feature Summary
- High thermal stability with a maximum operating junction temperature of +150°C
- Robust surge handling capability with a non-repetitive peak on-state current rating of 225 A
- Low leakage current of 10 uA in the off-state for efficient power management
- Integrated glass-passivated junctions for long-term parameter stability
Applications
- Industrial motor speed control systems
- Solid-state relays requiring high current capacity
- AC power regulation and phase control circuits
- Battery charging equipment with high surge tolerance
Procurement Notes
Verify the specific suffix 'N1' against official Littelfuse documentation to confirm pinout orientation or marking variations compared to standard variants. Confirm RoHS compliance status and REACH SVHC details directly from the manufacturer's latest datasheet before integration into regulated supply chains.
Selection Notes
Select this component when designs require a 16 A continuous current rating with a 400 V blocking voltage in a through-hole format. Ensure the gate drive circuit can supply at least 30 mA to guarantee reliable turn-on under all operating conditions and temperature ranges specified in the electrical characteristics table.
Part Context
This SCR belongs to the SJxx16xx family, which provides standardized high-current thyristor solutions for industrial power control. The SJ4016N1TP shares core electrical specifications with other members of the series, differing primarily in packaging markings or minor mechanical tolerances defined by the manufacturer's internal coding system.
Replacement Considerations
Direct substitutes must match the 16 A ItRMS, 400 V VDRM, and TO-220-2 package constraints. Verify equivalent gate trigger currents and holding currents to ensure circuit compatibility without redesigning the drive stage.
