Overview
The Littelfuse SJ4016L1TP is a Silicon Controlled Rectifier (SCR) belonging to the SJxx16xx series, designed for through-hole mounting in TO-220-2 packages. It features a rated repetitive off-state voltage (VDRM) of 400 V and an on-state RMS current (It RMS) of 16 A. The device exhibits a forward voltage drop (Vf) of 1.6 V, with a gate trigger voltage (Vgt) of 1.5 V and a gate trigger current (Igt) of 20 mA. Maximum holding current (Ih) is specified at 50 mA, while non-repetitive peak on-state current reaches 225 A. Leakage current under VDRM conditions is limited to 10 uA. Operating temperatures range from -40 C to +150 C.
Feature Summary
- High thermal stability enabling reliable operation up to +150 C junction temperature
- Robust surge handling capability with 225 A non-repetitive peak on-state current rating
- Low gate sensitivity requiring only 20 mA trigger current for efficient control
Applications
- Industrial motor drive circuits
- AC power control systems
- Solid state relay implementations
Procurement Notes
Verify component authenticity by cross-referencing the manufacturer part number SJ4016L1TP with official Littelfuse documentation. Confirm package type matches TO-220-2 specifications. Ensure supply chain sources provide valid traceability records. Check for RoHS compliance status if required by specific design constraints. Validate datasheet revisions to ensure parameter accuracy before final integration.
Selection Notes
Select this SCR when a 400 V blocking voltage and 16 A continuous current capacity are required in a standard TO-220-2 footprint. Compare gate trigger current requirements against available drive circuitry capabilities. Evaluate thermal management needs based on the 1.6 V forward voltage drop at operating currents. Consider the 50 mA holding current limit for latch-up prevention in low-load scenarios compared to alternative thyristor options.
Part Context
This component belongs to the SJxx16xx family of silicon controlled rectifiers manufactured by Littelfuse. These devices are engineered for general-purpose power switching applications requiring robust performance in industrial environments. The SJ4016L1TP shares core electrical characteristics with siblings like the SJ4016LTP and SJ4016L2TP, differing primarily in gate trigger parameters and holding current thresholds within the same voltage and current class.
Replacement Considerations
Direct substitutes include SJ4016LTP and SJ4016L2TP from the same Littelfuse series. Verify compatibility by comparing gate trigger current and holding current specifications against existing circuit designs. Ensure physical pinout alignment in the TO-220-2 package. Confirm that voltage and current ratings meet or exceed original system requirements.
