Overview
The Littelfuse SK012NTP is a silicon-controlled rectifier (SCR) designed for high-voltage power control applications. It features a standard recovery type with a maximum repetitive peak off-state voltage of 1 kV and an on-state RMS current rating of 12 A. The device is housed in a TO-220AB through-hole package, supporting a junction temperature range from -40°C to 125°C. Key electrical characteristics include a maximum gate trigger voltage of 1.5 V, a maximum gate trigger current of 20 mA, and a maximum on-state voltage of 1.6 V at 7.6 A average on-state current. Non-repetitive surge currents are rated at 100 A for 50 Hz and 120 A for 60 Hz frequencies.
Feature Summary
- Standard recovery characteristic suitable for general-purpose AC power control
- High voltage blocking capability up to 1 kV for robust circuit protection
- Through-hole TO-220AB packaging for efficient heat dissipation and mechanical stability
Applications
- Industrial motor speed control systems
- Solid-state relays and contactors
- AC power switching circuits
Procurement Notes
Verify the specific suffix 'NTP' against official Littelfuse documentation to confirm pinout configuration and manufacturing lot details. Ensure compatibility with existing thermal management designs given the TO-220AB form factor. Cross-reference datasheet parameters such as holding current and latching current against system requirements before finalizing procurement orders.
Selection Notes
Select this component when a 1 kV blocking voltage and 12 A RMS current capacity are required in a standard recovery SCR. The TO-220AB package is appropriate for applications needing reliable through-hole mounting and adequate thermal performance without active cooling. Verify that the gate trigger specifications align with the driving circuit's output capabilities.
Part Context
This part belongs to the Littelfuse SK series of silicon-controlled rectifiers, which are widely used in industrial power electronics. The SK series offers various voltage and current ratings packaged in TO-220AB or similar through-hole formats. These devices are engineered for durability in demanding environments, providing a balance of electrical performance and mechanical robustness for long-term operation.
Replacement Considerations
Consult official Littelfuse substitution guides for verified equivalents. Generic replacements must match the 1 kV voltage rating, 12 A RMS current, TO-220AB package, and standard recovery type to ensure functional compatibility.
