S2010VTP

Overview

The Littelfuse S2010VTP is a Silicon Controlled Rectifier (SCR) from the SK series, designed for high-power switching applications. It features a maximum repetitive off-state voltage (VDRM) of 1 kV and an RMS on-state current (IT(RMS)) of 10 A. The device supports a non-repetitive peak on-state current of 100 A and operates within a junction temperature range of -40°C to +125°C. Key electrical parameters include a maximum gate trigger voltage (VGT) of 1.5 V, a gate trigger current (IGT) of 15 mA, and a holding current (IH) maximum of 30 mA. It exhibits a forward voltage drop (VF) of 1.6 V at rated current and maintains an off-state leakage current (IDRM) of 20 µA. The component is housed in a TO-251 package with through-hole mounting.

Feature Summary

• High-voltage blocking capability suitable for demanding power control circuits
• Robust surge current handling for transient load conditions
• Standardized thermal performance for reliable operation in elevated temperature environments

Applications

• Industrial motor control systems
• Solid-state relay implementations
• Power regulation circuits requiring high voltage isolation

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure correct packaging and variant selection. Confirm that the TO-251 through-hole package aligns with the target PCB layout requirements. Cross-reference the electrical ratings with the system's maximum operating conditions to guarantee adequate safety margins for voltage and current stresses during procurement planning.

Selection Notes

Select this component when a 1 kV blocking voltage and 10 A continuous current rating are required in a compact form factor. Ensure the application can accommodate the specified gate drive characteristics, specifically the 1.5 V trigger voltage and 15 mA trigger current. Verify that the thermal management design supports the +125°C maximum junction temperature limit under expected load profiles.

Part Context

This SCR belongs to the Littelfuse SK series, which provides general-purpose thyristors for industrial and commercial power control. The series is characterized by robust construction and standardized pinouts, facilitating integration into various power electronics designs. The TO-251 package offers a balance between current carrying capacity and board space efficiency compared to larger axial leads.

Replacement Considerations

Consult the official Littelfuse replacement guide for verified cross-reference part numbers. Ensure any substitute device matches the 1 kV voltage rating, 10 A current rating, and TO-251 package dimensions to maintain mechanical and electrical compatibility.
