CS45-16IO1

Overview

The IXYS CS45-16IO1 is a phase control thyristor designed for line frequency applications. It features a rated repetitive off-state voltage (VDRM) of 1600 V and an RMS on-state current (IT(RMS)) of 75 A. The device supports a maximum average on-state current (IT(AV)M) of 48 A at a case temperature of 75°C with a 180° sine wave conduction angle. Surge current ratings reach up to 560 A for 8.3 ms at 60 Hz. Key electrical parameters include a forward voltage drop (VT) of 1.64 V at 80 A, a gate trigger voltage (VGT) of 1.5 V, and a gate trigger current (IGT) of 100 mA. The component operates within a junction temperature range of -40°C to +140°C and utilizes the ISOPLUS 247 package.

Feature Summary

• Planar passivated chip construction ensures long-term stability of blocking currents and voltages.
• ISOPLUS 247 package provides isolated mounting capabilities with UL registration.
• Epoxy material meets UL 94V-0 flammability standards.

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 against official documentation to confirm physical attributes. The io1 designation indicates a standard mounting configuration requiring a torque between 0.8 and 1.2 Nm for M3 screws. Confirm isolation requirements as the io1R variant specifies a different mounting force range of 20 to 120 N using a clip. Ensure compatibility with the intended thermal management strategy given the specified thermal resistance values.

Selection Notes

Select this component based on the required voltage rating of 1600 V and current handling capacity of 75 A RMS. Evaluate the thermal environment to ensure the case temperature remains within limits for the desired average current. Consider the gate drive characteristics, specifically the 1.5 V trigger voltage and 100 mA trigger current, when designing the control circuitry. Verify that the surge current capability meets the peak demands of the application during startup or fault conditions.

Part Context

This part belongs to the IXYS CS 45 series of phase control thyristors. The series includes variants with different voltage ratings, such as the CS45-08io1 for 800 V and CS45-12io1 for 1200 V. All models share similar current ratings and package types, allowing for standardized mechanical design across different voltage levels in power electronics projects.

Replacement Considerations

Direct substitutes are not explicitly listed in the provided datasheet. Designers should evaluate other IXYS CS 45 series components or comparable high-voltage SCR devices from other manufacturers that match the 1600 V rating, 75 A RMS current, and TO-247/ISOPLUS 247 package dimensions.

FAQ

What is the maximum non-repetitive surge current for the CS45-16IO1?

The maximum non-repetitive surge current is 560 A for an 8.3 ms duration at 60 Hz with VR = 0 V, or 520 A for a 10 ms duration at 50 Hz with TVJ = 45°C.

How does the gate trigger current vary with temperature?

At a junction temperature of 25°C, the gate trigger current is 100 mA. At -40°C, it increases to 200 mA.

What is the isolation voltage rating for the leads-to-tab?

The isolation voltage is 2500 V RMS at 50/60 Hz for a duration of one minute.
