SV6012N1QTP

Scrs Overview

The Littelfuse SV6012N1QTP is a high junction temperature Silicon Controlled Rectifier (SCR) in the SVxx12xxQ series, housed in an isolated TO-263 (D²Pak) surface-mount package. It features a 600 V repetitive peak reverse voltage and a 12 A RMS on-state current rating at a case temperature of 135°C. The device has a maximum gate trigger current of 6 mA and a maximum gate trigger voltage of 1.5 V. It supports a peak non-repetitive surge current of 180 A at 60 Hz and operates within a junction temperature range of -40°C to 150°C.

Scrs Feature Summary

• High dv/dt performance with low turn-off time for reliable switching
• Internally constructed isolated package for ease of heat sinking
• Halogen-free and RoHS compliant construction
• Recognized to UL 1557 as an electrically isolated semiconductor device

Scrs Applications

• AC generator rectifiers
• Battery voltage regulators
• Generic converters and inrush current controllers
• Power tool controls
• Home appliance controls

Scrs Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm the packing mode. The SV6012N1QTP designation indicates tube packaging; alternative reel options exist under different suffixes. Confirm that the component meets the required environmental standards and agency approvals for the intended application before finalizing procurement.

Scrs Selection Notes

Select this component when a surface-mount SCR with high thermal tolerance is required. Ensure the design limits continuous current to 75% of the rated value to extend operating life. Verify that the circuit can handle the specified peak surge current and that the gate drive provides sufficient voltage and current to trigger the device reliably across the full operating temperature range.

Scrs Part Context

This part belongs to the SVxx12xxQ series of 12 Amp high junction temperature SCRs. The 'N' designation identifies the TO-263 (D²Pak) surface-mount package, while the '1' indicates a standard sensitivity gate trigger level of 6 mA. The 'Q' suffix denotes the low turn-off time variant within the series.

Scrs Replacement Considerations

Other members of the SVxx12xxQ family share similar electrical characteristics but differ in package type or gate sensitivity. For example, SV6012L1QTP uses a TO-220L package, and SV6012N2QTP offers 10 mA gate sensitivity. Verify pinout compatibility and thermal resistance differences when substituting.
