Overview
The IXYS MCC44-16IO1B is a dual thyristor module designed for panel mounting in the TO-240AA package with seven pins. It features a repetitive peak reverse voltage of 1600 V and an RMS on-state current rating of 80 A. The device supports a surge current capacity of 5.3 kA, with a maximum gate trigger current of 150 mA and a peak on-state voltage of 1.5 V. Operating within a temperature range from -40°C to 125°C, it utilizes direct copper-bonded Al2O3 ceramic substrates for thermal management.
Feature Summary
- Dual configuration integrating two SCRs in a single compact unit
- Direct copper-bonded Al2O3 ceramic substrate for efficient heat dissipation
- Planar passivated chips ensuring stable electrical performance
- Screw-mount terminal design compatible with standard PCB layouts
Applications
- Industrial motor control systems
- High-power rectifier power supplies
- Industrial heating control circuits
- Static VAR compensation units
Procurement Notes
Verify the specific suffix 'B' against official datasheets to confirm exact pinout and mechanical dimensions. Ensure thermal interface materials are rated for the specified operating temperature range. Confirm that the gate drive circuitry provides sufficient current to meet the 150 mA trigger requirement under all load conditions.
Selection Notes
Select this component when a dual SCR topology is required for phase control or rectification applications. Compare the 80 A RMS current rating against the system's continuous load requirements. Evaluate the TO-240AA footprint against available board space and verify that the 1600 V blocking voltage exceeds the peak line voltage plus safety margins.
Part Context
This part belongs to the IXYS MCC series of high-current thyristor modules. The series is characterized by robust construction using vacuum-hydrogen protected welding techniques. These modules are engineered for reliability in demanding industrial environments where high power density and thermal cycling resistance are critical.
Replacement Considerations
Cross-reference with other IXYS MCC series variants such as MCC44-12IO1B for lower voltage ratings. Verify compatibility with alternative manufacturers offering similar TO-240AA dual SCR packages. Ensure that any substitute maintains equivalent thermal resistance and gate trigger characteristics.
