Overview
The IXYS MCD310-18IO1 is a thyristor/diode module rated for 500 A RMS and 320 A average forward current. It features a maximum repetitive peak reverse voltage of 1800 V and a surge current capacity of up to 9800 A at 8.3 ms. The device utilizes direct copper bonded Al2O3 ceramic base plates with planar passivated chips, providing an isolation voltage of 3600 V. Key electrical parameters include a gate trigger current of 150 mA, a peak on-state voltage of 1.32 V, and a junction temperature range from -40°C to +140°C.
Feature Summary
- Direct copper bonded Al2O3 ceramic base plate construction
- Planar passivated chip technology
- Keyed gate/cathode twin pin configuration
Applications
- Motor control systems
- Power converters
- Industrial furnace heat and temperature control
- Lighting control circuits
Procurement Notes
Verify the specific version suffix against official datasheets to confirm the exact voltage rating, as the MCC/MCD series spans multiple voltage classes. Confirm mounting torque specifications (M5: 2.5-5 Nm) during installation to ensure mechanical integrity and proper thermal contact.
Selection Notes
Select this module based on its 1800 V blocking capability and 500 A RMS current handling. Evaluate thermal management requirements using the provided transient thermal impedance curves. Ensure the application circuit can handle the specified di/dt and dv/dt critical limits to prevent device failure.
Part Context
This component belongs to the IXYS MCC/MCD 310 series of thyristor modules. The series offers standardized international packaging and includes variants with different voltage ratings ranging from 800 V to 2200 V. The MCD designation specifically indicates a thyristor/diode configuration within this family.
Replacement Considerations
Cross-reference with other IXYS MCD310 variants such as MCD310-16IO1 or MCD310-14IO1 if lower voltage ratings are acceptable. Verify that any substitute maintains the same Y2-DCB package dimensions and terminal layout for mechanical compatibility.
