Overview
The ST2600C26R0 is a phase control thyristor from the ST2600C..R series, featuring a Hockey Puk (R-PUK) case style with ceramic insulation. It supports a maximum repetitive off-state voltage of 2600 V and a peak non-repetitive surge current of 46,000 A at 50 Hz. The device delivers a maximum average on-state current of 2,220 A at an 80 °C case temperature or 2,630 A at a 55 °C heatsink temperature. It operates with a typical turn-off time of 400 µs and a maximum junction temperature of 125 °C.
Feature Summary
- Double side cooling capability for enhanced thermal management
- High surge current handling capacity
- Fatigue-free construction for long-term reliability
- High mean current rating
Applications
- DC motor controls
- Controlled DC power supplies
- AC controllers
Procurement Notes
Verify the specific ordering suffix against the manufacturer's documentation to confirm terminal type and critical dv/dt ratings. The base part number indicates the voltage code, but suffixes define physical connection details such as eyelet or fast-on terminals. Ensure compatibility with required mounting forces and thermal interface materials for the R-PUK package.
Selection Notes
Select this component for high-power applications requiring robust surge handling and precise phase control. Evaluate thermal resistance requirements based on single or double-side cooling configurations. Confirm that the gate drive circuitry can supply the necessary peak currents and voltages without exceeding maximum gate power limits during triggering operations.
Part Context
This device belongs to the ST2600C..R series of phase control thyristors manufactured by Vishay General Semiconductor - Diodes Division. The series utilizes a rugged Hockey Puk design intended for heavy-duty industrial environments. These components are engineered for high-voltage and high-current switching tasks where reliability under extreme electrical stress is critical.
Replacement Considerations
Consult official substitution guides for equivalent high-voltage phase control thyristors. Verify matching voltage codes, current ratings, and mechanical dimensions before replacing existing units in established designs.
