Scrs datasheet and documents for VS-50RIA120M
Scrs Overview
The VS-50RIA120M is a medium power phase control thyristor from the Vishay Semiconductors VS-50RIA series. It features a maximum average on-state current (IT(AV)) of 50 A and a maximum RMS on-state current (IT(RMS)) of 80 A. The device supports a maximum repetitive peak off-state voltage (VDRM/VRRM) of 1200 V, indicated by the '120' code suffix. It utilizes a TO-65 (TO-208AC) stud package with an M6 x 1 metric thread. Key electrical parameters include a maximum on-state voltage (VTM) of 1.60 V, a gate trigger current (IGT) of 100 mA at 25 °C, and a junction temperature range of -40 to +125 °C.
Scrs Feature Summary
- High surge capability with non-repetitive peak currents up to 1490 A at 60 Hz
- Robust dynamic characteristics including high dI/dt ratings
- Standardized mounting interface with metric threading options
Scrs Applications
- Phase control applications in converters
- Lighting circuits
- Battery chargers
- Regulated power supplies
- Temperature and speed control circuits
Scrs Procurement Notes
Verify the specific voltage rating corresponds to the '120' suffix indicating 1200 V. Confirm the presence of the 'M' suffix for the M6 x 1 metric thread variant rather than the standard imperial thread. Ensure the ordering code includes the complete sequence: VS-, 50, RIA, 120, M. Check for any special selection codes like S90 if higher critical dV/dt is required.
Scrs Selection Notes
Select this component when a single SCR requires 50 A continuous current handling and 1200 V blocking voltage. The TO-65 package facilitates direct heat sink mounting via the stud base. Consider the thermal resistance values for proper heatsink design. Verify that the application's gate drive requirements align with the specified IGT and VGT limits across the operating temperature range.
Scrs Part Context
This part belongs to the VS-50RIA series of medium power phase control thyristors manufactured by Vishay Semiconductors. The series offers various voltage ratings from 100 V to 1200 V within the same physical footprint. The 'M' designation specifically denotes the availability of metric threads for the stud mount configuration, providing flexibility for international manufacturing standards.
Scrs Replacement Considerations
Direct substitutes within the same series include VS-50RIA100M (1000 V) or VS-50RIA80M (800 V) if lower voltage ratings are acceptable. For higher voltage requirements, verify compatibility with other Vishay thyristor families sharing the TO-65 package dimensions.
