Overview
The IXYS MCC21-14IO8B is a discrete semiconductor module classified as a thyristor. It utilizes silicon technology and is housed in a TO-240AA package with screw mount installation style. The device supports an output current of 21 A and withstands a voltage rating of 1400 V. Key electrical parameters include a gate trigger current (Igt) of 65 mA and a maximum holding current (Ih) of 100 mA. The operational temperature range spans from -40 C to +100 C, with a unit weight of 83 g.
Feature Summary
- Integrated thyristor configuration within a single discrete semiconductor module
- Designed for screw mount installation using the TO-240AA package format
- Operates reliably across a wide temperature range from -40 C to +100 C
Applications
- Industrial power control systems requiring thyristor modules
- High-voltage DC circuit protection applications
- General purpose power electronics utilizing discrete semiconductor modules
Procurement Notes
Verify the specific ordering suffix IO8B against the manufacturer's latest datasheet to confirm pinout and terminal configuration. Ensure that the TO-240AA package dimensions align with the intended heatsink or mounting hardware specifications before integration into the final assembly design.
Selection Notes
Select this component when a 21 A continuous current rating and 1400 V blocking voltage are required in a compact form factor. Consider the 65 mA gate trigger current for driver circuit compatibility. Verify that the +100 C maximum operating temperature meets the thermal management requirements of the target application environment.
Part Context
This part belongs to the MCC series of thyristor modules manufactured by IXYS. It shares the TO-240AA package style with other variants in the lineup, such as the MCC21-08IO8B and MCC21-12IO8B, which differ primarily in their voltage ratings while maintaining similar current capabilities.
Replacement Considerations
Direct substitutes within the same series include the MCC21-08IO8B and MCC21-12IO8B, though these offer lower voltage ratings. Cross-series replacements require careful verification of the TO-240AA footprint and electrical parameter alignment.
