CS45-16IO1R

Overview

The IXYS CS45-16IO1R is a phase control thyristor rated for a repetitive peak reverse voltage of 1600 V and an RMS on-state current of 75 A. It utilizes the ISOPLUS 247 package, providing electrical isolation between the leads and the tab. The device supports a maximum average on-state current of 48 A at a case temperature of 75°C with a 180° sine wave conduction angle. Key electrical parameters include a forward voltage of 1.64 V at 80 A, a gate trigger current of 100 mA, and a non-repetitive surge current capability of 560 A. The component operates within a junction temperature range of -40°C to +140°C.

Feature Summary

• Features an isolated back surface design that electrically separates the mounting tab from the internal circuitry.
• Utilizes a planar passivated chip structure to ensure long-term stability of blocking currents and voltages.
• Complies with international JEDEC TO-247 standards while offering space and weight savings compared to traditional packages.

Applications

• Motor control systems
• Power converters
• AC power controllers
• Switch-mode and resonant mode power supplies
• Light and temperature control circuits

Procurement Notes

Verify the specific ordering suffix io1R to confirm the inclusion of the mounting clip mechanism, which requires a force of 20 to 120 N rather than a screw torque specification. Ensure the application environment remains within the specified thermal limits and that the isolation voltage rating of 2500 Vrms is sufficient for the intended circuit insulation requirements.

Selection Notes

Select this component when high voltage blocking capability up to 1600 V is required alongside significant current handling in a compact form factor. The isolated tab configuration simplifies heatsinking without additional insulators. Verify that the gate drive circuit can supply the necessary trigger current and that the di/dt rating of 150 A/µs is not exceeded during turn-on to prevent device failure.

Part Context

This part belongs to the IXYS CS 45 series of line frequency phase control thyristors. The series includes variants with different voltage ratings, such as the CS45-08io1 (800 V) and CS45-12io1 (1200 V). All models share similar current ratings and package dimensions, differing primarily in their maximum repetitive peak reverse voltage capabilities.

Replacement Considerations

Direct substitutes within the same family include the CS45-16io1, which shares identical electrical characteristics but uses a screw-mounting method instead of a clip. Other voltage-rated variants like the CS45-12io1 or CS45-08io1 may be used if lower voltage ratings are acceptable for the specific application.
