This document describes the features and characteristics of the Phase Control Thyristors -Phaseleg Topology- in ISOPLUS i4-PACTM 1 5 FCC 21-12io produced by IXYS, including long-term stability, high reliability, low coupling capacity, and enlarged creepage distance. The product is suitable for controlled rectifiers, power supplies, and drives.
This document is a preliminary datasheet for the IXYS FCC 21-12io Phase Control Thyristor. The device utilizes chip technology within an ISOPLUS i4-PAC package featuring an isolated back surface and low coupling capacity between pins and heatsink.
The thyristor is designed for line frequency applications in controlled rectifiers, power supplies, drives, and AC switches. Key maximum ratings include a repetitive peak off-state voltage (VDRM) of 1200 V and an average on-state current (IT(AV)) of 21 A under sine wave conditions.
| Repetitive Peak Off-State Voltage (VDRM) | 1200 V |
|---|---|
| Average On-State Current (IT(AV)) sine wave | 21 A |
| Non-Repetitive Surge Current (ITSM) | 300 A |
| Operating Temperature Range (TVJ) | -40...+125 °C |
| Storage Temperature Range (Tstg) | -55...+125 °C |
| Isolation Voltage (VISOLISOL) | 2500 V~ |
| Coupling Capacity between pins and mounting tab | 40 pF |
The device uses an ISOPLUS i4-PAC TM package with an isolated back surface.
It is suitable for controlled rectifiers, power supplies, drives, and AC switches.
