S6006VTP

Overview

The Littelfuse S6006VTP is a single-element Silicon Controlled Rectifier (SCR) designed for general-purpose switching applications. It features a rated repetitive off-state voltage of 600 V and an on-state RMS current of 6 A. The device utilizes a TO-251AA (DPAK) surface-mount package with three terminals, where the case is connected to the anode. Key electrical characteristics include a maximum DC gate trigger current of 15 mA and a maximum DC gate trigger voltage of 1.5 V. It exhibits a critical rate of rise of off-state voltage of 225 V/µs and a maximum holding current of 30 mA. The component operates within a temperature range defined by its standard industrial ratings and complies with RoHS directives.

Feature Summary

• Sensitive gate structure allows for direct interfacing with low-power control circuits
• Anode-connected case facilitates efficient thermal dissipation through PCB mounting
• Glass passivated junction provides durability against environmental stress

Applications

• Strobe light triggering circuits
• Fluid level sensing systems
• Capacitive-discharge ignition systems

Procurement Notes

Verify the specific datasheet revision and manufacturer documentation to confirm exact parameter tolerances and testing conditions. Ensure that the TO-251AA package footprint matches the target PCB design. Confirm compliance requirements such as RoHS status and lead-free soldering compatibility with assembly processes before finalizing procurement specifications.

Selection Notes

Select this component when a surface-mount SCR with moderate current handling and sensitive gate drive is required. The 6 A RMS rating suits low-current switching tasks. Consider the anode-connected case for thermal management needs. Verify that the 600 V blocking voltage meets the circuit's peak reverse voltage requirements and that the gate trigger parameters align with the available control signal levels.

Part Context

The S6006VTP belongs to Littelfuse's discrete silicon-controlled rectifier family, which offers solutions for precise switching in low-current circuits. These devices are engineered for efficient operation with minimal gate current activation. The product line includes various packages and ratings to support diverse electronic control applications across industrial and consumer sectors.

Replacement Considerations

Cross-reference with other Littelfuse SCRs in the same voltage and current class if availability is constrained. Verify pinout compatibility, specifically the anode-connected case configuration in TO-251AA packages. Ensure substitute parts maintain equivalent gate sensitivity and thermal performance characteristics.
