VS-ST330C04C1

Scrs Overview

The VS-ST330C04C1 is a Silicon Controlled Rectifier (SCR) manufactured by Vishay General Semiconductor - Diodes Division. It features a standard recovery type with a maximum repetitive peak off-state voltage of 400 V and an RMS on-state current rating of 780 A. The device utilizes a TO-200AB (A-PUK) clamp-style package, supporting a maximum average on-state current of 410 A. Key electrical parameters include a maximum non-repetitive surge current of 5000 A at 60 Hz, a maximum gate trigger voltage of 3 V, and a maximum on-state voltage of 1.69 V. It operates within a junction temperature range of -40°C to 125°C.

Scrs Feature Summary

• High current handling capability with 780 A RMS on-state current rating for robust power control applications.
• Standard recovery characteristics suitable for general-purpose rectification and switching tasks.
• Robust mechanical design utilizing a clamp-style TO-200AB package for secure mounting and thermal management.

Scrs Applications

• Industrial motor drives requiring high-current AC/DC conversion
• Resistive load control systems in manufacturing environments
• Power supply units needing reliable phase-angle control

Scrs Procurement Notes

Verify the specific suffix C1 against official Vishay documentation to confirm pinout and terminal configuration compatibility. Confirm RoHS3 compliance status as per the latest datasheet revision. Check for End-of-Life notices or Product Change Notifications that may affect long-term availability. Ensure mounting hardware matches the A-PUK package requirements for proper thermal interface.

Scrs Selection Notes

Select this component when a 400 V blocking voltage and 780 A RMS current capacity are required in a clamp-mountable form factor. Compare the 1.69 V on-state voltage drop against system efficiency targets. Ensure the gate trigger specifications align with the available drive circuitry capabilities. Verify that the TO-200AB package dimensions fit the designated heatsink or chassis constraints.

Scrs Part Context

This SCR belongs to the ST230 series from Vishay, designed for medium-to-high power applications. The series offers various voltage ratings while maintaining consistent current handling and package styles. The TO-200AB format provides a standardized footprint for industrial power electronics, facilitating replacement in existing designs requiring similar thermal and electrical performance profiles.

Scrs Replacement Considerations

Direct substitutes must match the 400 V rating, 780 A RMS current, and TO-200AB A-PUK package. Verify identical gate trigger characteristics and on-state voltage drops to ensure circuit stability. Cross-reference Vishay's official substitution guides for approved equivalent part numbers.
