S2010VS2TP

Overview

The Littelfuse S2010VS2TP is a sensitive silicon-controlled rectifier (SCR) rated for 10 A on-state current and 400 V repetitive peak off-state voltage. It utilizes an electrically isolated TO-220 package with the mounting tab internally isolated from the leads, allowing for high-voltage potential testing up to 4000 V ac rms. The device features glass-passivated junctions for reliability and offers a DC gate trigger current of 200 µA. Key electrical parameters include a maximum non-repetitive surge current of 100 A, a critical rate-of-rise of forward off-state voltage of 250 V/µs, and a typical peak on-state voltage of 1.6 V.

Feature Summary

• Electrically isolated TO-220 package enables safe high-voltage mounting
• Glass-passivated chip junction ensures long-term parameter stability
• High sensitivity gate control reduces required trigger power

Applications

• Half-wave unidirectional rectification in low-power circuits
• Gate drive triggering for larger power thyristors
• Lighting control systems requiring sensitive switching

Procurement Notes

Verify the specific isolation rating requirement before ordering. The 'V' suffix indicates optional 4000 V isolation compared to the standard 2500 V rating. Confirm that the TO-220 lead configuration matches the PCB layout. Ensure the application does not exceed the 10 A continuous current limit at the expected case temperature.

Selection Notes

Select this component when a 400 V blocking capability and 10 A load current are required within an isolated package. The 200 µA gate sensitivity suits applications where minimal control signal strength is available. Consider thermal derating curves if operating near the 110 °C maximum junction temperature limit or under repetitive surge conditions.

Part Context

This part belongs to the Teccor line of sensitive SCRs manufactured by Littelfuse. It complements the broader portfolio of power SCRs by offering lower current ratings with enhanced gate sensitivity. The device is designed for general-purpose switching and rectification tasks where electrical isolation between the control circuit and the load is necessary.

Replacement Considerations

Direct replacements must match the 10 A current rating, 400 V voltage rating, and isolated TO-220 package. Verify that substitute devices offer comparable gate trigger currents and dv/dt ratings to ensure reliable operation without false triggering.
