VS-ST330C14C0L

Scrs Overview

The VS-ST330C14C0L is a standard recovery silicon controlled rectifier (SCR) manufactured by Vishay General Semiconductor. It features a 1400 V repetitive peak off-state voltage and supports an RMS on-state current of 1420 A, with an average on-state current rating of 720 A. The device utilizes a TO-200AB (E-PUK) clamp-on package for chassis mounting. Key electrical parameters include a maximum gate trigger voltage of 3 V and a maximum on-state voltage of 1.96 V. It operates within a junction temperature range of -40°C to 125°C.

Scrs Feature Summary

• High-power handling capability with 1420 A RMS on-state current rating
• Robust 1400 V blocking voltage for high-voltage industrial applications
• Standard recovery characteristics suitable for phase control circuits
• Durable TO-200AB E-PUK clamp-on package design

Scrs Applications

• Industrial motor drives and variable frequency drives
• High-power DC power supply systems
• Resistive load control in heavy industry
• Welding equipment power stages

Scrs Procurement Notes

Verify the specific suffix 'L' against official Vishay documentation to confirm exact pinout or mechanical variations compared to the base VS-ST330C14C0 model. Ensure compatibility with existing heatsink mounting hardware designed for the TO-200AB E-PUK form factor. Confirm that the standard recovery type aligns with your circuit's switching speed requirements and dv/dt ratings.

Scrs Selection Notes

Select this component when high current capacity and robust voltage blocking are required in a clamp-on configuration. The 1420 A RMS rating suits heavy-duty applications where thermal management via chassis mounting is feasible. Consider the standard recovery time if fast switching is not critical. Ensure the gate drive circuit can provide sufficient current to trigger the device reliably under all operating conditions.

Scrs Part Context

This SCR belongs to the VS-ST330 series, which offers high-current solutions in the TO-200AB package. The series includes variants with different voltage ratings such as 400V, 800V, 1200V, and 1400V. The VS-ST330C14C0L represents the 1400V variant, providing a balance between high voltage tolerance and significant current carrying capacity for demanding power electronics designs.

Scrs Replacement Considerations

Direct substitutes may include other 1400V, 1420A SCRs in TO-200AB packages from Vishay or competitors like Littelfuse or Semikron. Verify matching electrical parameters, specifically I_T(RMS), V_DRM, and package dimensions. Cross-reference datasheets for gate trigger requirements and thermal resistance values to ensure equivalent performance in the target application.
