Overview
The ST2100C38R0 is a phase control thyristor from the 2090A series, manufactured by Vishay General Semiconductor - Diodes Division. It utilizes the R-PUK hockey puck case style with ceramic insulation and eyelet terminals. The device supports a maximum repetitive peak off-state voltage of 3800 V. Key electrical ratings include a maximum average on-state current of 1770 A at an 80 °C case temperature, and 2090 A at a 55 °C heatsink temperature. The RMS on-state current reaches 3850 A under double-side cooling conditions at a 25 °C heatsink temperature. Maximum surge capabilities are specified at 36250 A for 50 Hz and 38000 A for 60 Hz frequencies.
Feature Summary
- Double side cooling capability for enhanced thermal management
- High surge current handling capacity
- Fatigue free construction
- High mean current operation
Applications
- DC motor controls
- Controlled DC power supplies
- AC controllers
Procurement Notes
Verify the specific ordering suffix to confirm terminal type and critical dv/dt rating. The 'R' indicates the Puk case style, while the final digit determines if gate and auxiliary cathode leads are unsoldered or soldered. Confirm that the voltage code '38' corresponds to the required 3800 V rating. Ensure mounting hardware matches the R-PUK outline dimensions and torque specifications.
Selection Notes
Select this component based on the required blocking voltage and high current carrying capacity. Evaluate thermal resistance requirements for single or double side cooling configurations. Consider the maximum junction temperature limit of 125 °C during design. Verify gate trigger parameters against the driving circuit capabilities. Check conduction angle derating curves for non-sinusoidal load applications.
Part Context
This part belongs to the ST2100C..R series of phase control thyristors. The series offers various voltage codes ranging from 3000 V to 4200 V. All devices share the same R-PUK package and general electrical characteristics, differing primarily in their voltage ratings and terminal configurations. The series is designed for heavy industrial power conversion applications requiring robust performance.
Replacement Considerations
Substitute parts must match the R-PUK package dimensions and pinout. Verify equivalent voltage and current ratings. Check thermal resistance values for compatibility with existing heatsinking solutions. Ensure gate trigger characteristics align with the control circuitry.
