Overview
The Littelfuse S8008R is a Silicon Controlled Rectifier (SCR) designed for power control applications. It features an 8A RMS on-state current and a 5100mA average on-state current rating. The device supports a repetitive peak reverse voltage of 800V and a blocking voltage of 800V. It is housed in a TO-220AB plastic package with three terminals and flange mount configuration. Key electrical characteristics include a maximum DC gate trigger current of 15 mA, a maximum DC gate trigger voltage of 1.5 V, and a holding current of 30 mA. The component exhibits a critical rate of rise of off-state voltage of 200 V/us and a non-repetitive peak surge current capability of 100 A.
Feature Summary
- Sensitive gate structure allowing direct interfacing with microprocessors via low gate current requirements.
- Robust thermal management design utilizing a flange mount package for efficient heat dissipation.
- High surge current handling capability suitable for demanding switching environments.
Applications
- Strobe light circuits
- Fluid level sensors
- Capacitive-discharge ignition systems
Procurement Notes
Verify the specific suffix to confirm the exact package variant, as Littelfuse offers multiple packaging options for this series. Ensure compliance with RoHS standards if required by the target application. Cross-reference the datasheet for precise thermal resistance values during PCB layout planning. Confirm UL recognition status for safety-critical installations.
Selection Notes
Select this component when an 800V blocking voltage and 8A continuous current are required. Consider the TO-220AB package for through-hole mounting and heatsink compatibility. Evaluate the 15 mA gate trigger current against the driving circuit's output capabilities. Verify that the 200 V/us dv/dt rating meets the circuit's transient voltage requirements.
Part Context
This SCR belongs to Littelfuse's discrete silicon-controlled rectifier portfolio, optimized for efficient switching in low-current circuits. The product line emphasizes fast turn-off capabilities to reduce commutation failure risks. These devices are engineered for durability and sensitive gate operation, supporting various industrial and consumer electronics control functions.
Replacement Considerations
Check for equivalent SCRs from other manufacturers offering identical 800V ratings and TO-220AB packages. Verify pinout compatibility and thermal performance metrics before substitution. Ensure the replacement device meets the same UL recognition and RoHS compliance standards.
