S8006LTP

Overview

The Littelfuse S8006LTP is a standard recovery silicon controlled rectifier (SCR) designed for high-voltage switching and control applications. It features an 800 V repetitive peak off-state voltage and a 6 A average on-state current rating. The device utilizes a TO-220AB-L package with an isolated case connection, suitable for through-hole mounting. Key electrical characteristics include a maximum DC gate trigger current of 15 mA and an off-state leakage current of 10 uA at the rated voltage. This component provides reliable performance in power conversion systems requiring robust thyristor functionality.

Feature Summary

• Standard recovery thyristor construction optimized for efficient switching operations
• Isolated case configuration enabling secure mounting to heat sinks without electrical shorting
• Single-phase SCR architecture providing straightforward integration into control circuits

Applications

• DC motor control and drives
• Battery charging systems
• Industrial welding equipment
• Power converter topologies
• Lighting control circuits

Procurement Notes

Verify that the specific ordering suffix matches the required isolation and package style. Confirm that the thermal management design accommodates the TO-220AB-L form factor. Ensure the application voltage does not exceed the 800 V rating under all operating conditions. Check for compliance with RoHS directives if environmental regulations apply. Validate gate trigger specifications against the driver circuit capabilities before finalizing the procurement order.

Selection Notes

Select this component when an 800 V blocking capability and 6 A continuous current handling are required. The TO-220AB-L package offers a balance of thermal dissipation and board space efficiency. Consider the 15 mA gate trigger limit when designing the drive circuitry. The isolated case simplifies mechanical assembly in high-voltage environments. Evaluate thermal resistance requirements based on the expected duty cycle and ambient temperature conditions.

Part Context

This part belongs to the Littelfuse Sxx06x series of SCRs, which are engineered for general-purpose power control. The series provides standardized ratings for industrial applications. The S8006LTP specifically addresses needs for medium-power switching where high voltage isolation is critical. It complements other thyristors in the portfolio by offering a specific combination of voltage and current ratings in a widely used package style.

Replacement Considerations

Cross-reference with other 800 V, 6 A SCRs in the TO-220AB-L package. Verify pinout compatibility and thermal interface requirements. Ensure that substitute devices meet or exceed the 15 mA gate trigger current specification. Confirm that the replacement maintains the same off-state leakage current limits. Check for equivalent reverse voltage ratings to ensure system safety.
