R0736LC20J

Overview

The R0736LC20J is a Silicon Controlled Rectifier (SCR) phase control thyristor manufactured by IXYS. It is housed in an ISOPLUS247 package, which corresponds to the TO-247 form factor with three terminals. The device is designed for high-power applications requiring robust thermal performance and reliable switching characteristics. Key electrical parameters include a repetitive peak off-state voltage of 600 V and a gate trigger current of 100 mA. The component supports a maximum RMS on-state current of 20 A and can handle a non-repetitive surge current of 250 A. It operates within a junction temperature range of -40°C to +125°C.

Feature Summary

• ISOPLUS247 package design provides enhanced thermal dissipation capabilities for high-power density applications.
• Phase control architecture optimized for efficient AC power regulation and motor speed control systems.
• High surge current handling capacity ensures reliability during transient load conditions.

Applications

• Industrial motor speed drives
• AC power controllers
• Lighting dimmers

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure correct pinout and packaging configuration. Confirm RoHS compliance status through the latest product documentation before integration into regulated assemblies. Cross-reference the Mouser number 747-R0736LC20J with the original IXYS part number to validate authenticity and traceability during sourcing.

Selection Notes

Select this component when designing circuits requiring a 600 V blocking voltage and 20 A continuous current rating in a TO-247 compatible footprint. Ensure the application's thermal management system can maintain the junction temperature below 125°C under maximum load conditions. Verify that the gate drive circuitry can supply the required 100 mA trigger current for reliable turn-on.

Part Context

This SCR belongs to the IXYS phase control thyristor family, engineered for industrial power electronics. The ISOPLUS247 package variant offers superior heat transfer compared to standard TO-220 styles, making it suitable for medium-to-high power converters. It serves as a core switching element in systems demanding precise AC waveform control and robust fault tolerance.

Replacement Considerations

Direct substitutes must match the 600 V / 20 A specification and TO-247-3 package outline. Verify equivalent gate trigger characteristics and thermal resistance values. Consult manufacturer cross-reference lists for confirmed alternative part numbers from IXYS or other qualified suppliers.
