MCR08BT1G

Overview

The Littelfuse MCR08BT1G is a PNPN thyristor (SCR) in a surface-mount SOT-223 package. It features a sensitive gate trigger current and glass-passivated junctions for reliability. The device supports peak repetitive off-state voltages of 200 V (MCR08B) or 600 V (MCR08M). It handles an on-state RMS current of 0.8 A at 80°C case temperature and a non-repetitive surge current of 8.0 A. Operating junction temperatures range from -40°C to +110°C, with storage capabilities up to 150°C.

Feature Summary

Sensitive gate design allows direct interfacing with microprocessors
Glass passivated surface ensures long-term parameter stability
Surface mount construction facilitates automated manufacturing

Applications

Relay drivers
Lamp drivers
Small motor controls
Gate drivers for larger thyristors
Sensing and detection circuits

Procurement Notes

Verify the specific voltage rating suffix required for the application: 'B' indicates 200V blocking capability, while 'M' indicates 600V. Confirm the package type is SOT-223 and shipping quantity is 1000 units per tape and reel. Ensure lead-free RoHS compliance meets project specifications before finalizing orders.

Selection Notes

Select the MCR08BT1G variant based on the required blocking voltage; use the 'B' suffix for 200V applications and 'M' for 600V. Consider the thermal resistance characteristics when designing PCB copper tab areas to manage heat dissipation effectively. Verify that the sensitive gate requirements align with the driving circuit's output capabilities.

Part Context

This component belongs to the MCR08 series of surface-mount silicon-controlled rectifiers designed for line-powered consumer electronics. It serves as a compact switching solution for low-current control applications where space constraints necessitate surface-mount technology over through-hole alternatives.

Replacement Considerations

Direct replacements include the MCR08MT1G for higher voltage ratings within the same package. Cross-reference thermal derating curves if substituting with similar SCRs from other manufacturers to ensure equivalent performance under load.
