S8006RTP

Overview

The Littelfuse S8006RTP is a Silicon Controlled Rectifier (SCR) from the Teccor Sxx06x series, designed for phase control applications. It features an 800 V rated repetitive off-state voltage and conducts a 6 A RMS on-state current. The device utilizes a sensitive gate architecture, requiring a maximum gate trigger current of 15 mA at 1.5 V to initiate conduction. Packaged in a TO-220-2 (TO-220AB) through-hole configuration, it supports an operating temperature range from -40°C to +125°C. Key electrical characteristics include a holding current of 30 mA maximum and a non-repetitive peak surge current capability of 100 A.

Feature Summary

• Sensitive gate design enabling reliable triggering with low microampere currents from sense coils or microprocessors
• Glass-passivated junctions providing robust protection against environmental stressors
• High thermal stability suitable for demanding industrial and consumer appliance environments

Applications

• Phase control systems for heating elements
• Motor speed control circuits
• Capacitive discharge ignition systems for gas engines
• Power tool controls
• Strobe light capacitive discharge systems

Procurement Notes

Verify the specific suffix 'RTP' against the manufacturer's official documentation to confirm the exact packaging format and reel specifications. Ensure that the through-hole lead form matches the target PCB footprint requirements. Cross-reference the RoHS and REACH compliance status directly with the latest datasheet to meet regulatory standards for the intended market.

Selection Notes

Select this component when a sensitive gate SCR is required for precise phase control with minimal drive power. The 6 A RMS rating suits moderate power loads, while the 800 V blocking voltage provides adequate margin for standard AC line applications. Consider the TO-220 package for efficient heat dissipation without requiring complex mounting structures compared to smaller surface-mount alternatives.

Part Context

This part belongs to the Littelfuse Teccor Sxx06x family of Thyristors. This series is characterized by its combination of high voltage blocking capabilities and sensitive gate sensitivity. The S8006RTP specifically adapts these characteristics into a through-hole package, distinguishing it from surface-mount variants within the same electrical performance class.

Replacement Considerations

Direct replacements must match the 6 A RMS current, 800 V voltage, and sensitive gate threshold. Verify that alternative SCRs maintain the TO-220-2 pinout compatibility. Check if the substitute requires similar gate drive currents to ensure circuit interface integrity without modification.
