VS-180RKI100

Scrs Overview

The VS-180RKI100 is a standard recovery SCR manufactured by Vishay General Semiconductor - Diodes Division. It features a 1000 V DC reverse voltage rating and an on-state current of 180 A, with a maximum rated current of 285 A. The device supports non-repetitive peak on-state currents of 3800 A or 4000 A depending on the pulse width. Key electrical parameters include a maximum gate trigger voltage of 2.5 V, a maximum gate trigger current of 150 mA, and a maximum on-state voltage of 1.35 V. The holding current is limited to 600 mA, while the off-state leakage current does not exceed 30 mA. Operating temperatures range from -40°C to +125°C.

Scrs Feature Summary

• High power handling capability with 180 A continuous on-state current for industrial applications
• Robust surge tolerance supporting up to 4000 A non-repetitive peak current
• Standard recovery characteristics suitable for phase control and rectification
• Durable construction in TO-209AB (TO-93) base mount package

Scrs Applications

• Industrial motor drives and AC power controllers
• High-power rectifier circuits requiring robust surge protection
• Welding equipment power stages
• Induction heating systems

Scrs Procurement Notes

Verify the specific suffix code against the manufacturer's latest datasheet to confirm exact electrical tolerances and pinout configurations. Ensure the procurement documentation matches the required thermal resistance specifications for the intended heatsink interface. Confirm RoHS compliance status if environmental regulations apply to the final assembly. Cross-reference the part number with official Vishay distribution channels to avoid counterfeit components.

Scrs Selection Notes

Select this component when designing circuits requiring high current capacity and moderate switching speeds. The TO-209AB package necessitates board-level mounting considerations distinct from surface-mount alternatives. Evaluate the thermal management requirements based on the 1.35 V on-state voltage drop at full load. Ensure the gate drive circuit can supply the specified 150 mA trigger current reliably under all operating conditions.

Scrs Part Context

This SCR belongs to Vishay's general-purpose thyristor lineup designed for high-power industrial electronics. The TO-93 form factor provides a standardized footprint for legacy and modern power conversion designs. It serves as a discrete solution for controlling AC power in heavy-duty machinery where integrated modules are unsuitable due to cost or flexibility constraints.

Scrs Replacement Considerations

Consult Vishay's official substitution guide for equivalent devices within the RKI series. Verify that any alternative part maintains identical voltage ratings and current capabilities. Ensure mechanical compatibility with existing TO-93 mounting hardware before implementation.
