S8025L

Overview

The S8025L is a thyristor manufactured by Littelfuse, designed for high-reliability switching applications. It features an electrically isolated package and operates within a temperature range of -40°C to 125°C. The device supports a maximum voltage rating of 800V and requires a gate trigger current of 35 mA for activation. Constructed with a TO-220-3 through-hole package, it provides three terminals for secure mounting. This component serves as a unidirectional switch suitable for phase control circuits, offering robust performance in demanding electronic environments.

Feature Summary

• Electrically isolated package design for enhanced safety
• Unidirectional switching capability for phase control
• Through-hole mounting for secure mechanical stability

Applications

• Heating control systems
• Motor speed controls
• Phase control applications

Procurement Notes

Verify the specific Littelfuse datasheet version to confirm electrical parameters and thermal characteristics before integration. Ensure the TO-220-3 package dimensions match your PCB layout requirements. Check for RoHS compliance status if environmental regulations apply to your manufacturing process. Confirm that the 800V blocking voltage and 35mA gate trigger current align with your circuit design specifications to prevent operational failure.

Selection Notes

Select the S8025L when phase control functionality is required in heating or motor speed regulation circuits. Its 800V rating makes it suitable for higher voltage AC applications compared to lower-rated SCRs. The through-hole TO-220-3 package is ideal for prototypes or applications requiring robust mechanical mounting. Consider the 35mA gate trigger sensitivity for driver circuit compatibility. Evaluate thermal management needs given the 125°C maximum operating temperature limit.

Part Context

The S8025L belongs to Littelfuse's Teccor line of thyristor SCRs. These components are half-wave, unidirectional, gate-controlled rectifiers. They complement the manufacturer's sensitive SCR series by offering standard phase control capabilities. The product is engineered for reliability in industrial and consumer electronics where precise power switching is essential.

Replacement Considerations

Consult official Littelfuse documentation for direct cross-reference part numbers. Verify voltage, current, and package compatibility when substituting similar SCRs from other manufacturers. Ensure gate trigger characteristics match the existing circuit design to maintain proper switching behavior.
