Overview
The Littelfuse S8012VTP is a Silicon Controlled Rectifier (SCR) designed for high-temperature and high dv/dt applications. It features an RMS on-state current of 12 A and a rated repetitive peak off-state voltage of 800 V. The device operates within a temperature range of -40°C to +150°C and utilizes a TO-251-3 surface mount package. Key electrical characteristics include a maximum holding current of 40 mA, a gate trigger current of 20 mA, and a non-repetitive peak on-state current of 144 A.
Feature Summary
- Engineered for high-temperature operation up to 150°C
- High dv/dt capability for robust switching performance
- Surface mount construction in a compact TO-251-3 package
Applications
- Industrial power control systems
- Motor drive circuits
- High-temperature AC/DC conversion
Procurement Notes
Verify the specific suffix 'VTP' against the manufacturer's official datasheet to confirm the exact pinout and thermal specifications. Ensure that the procurement documentation explicitly references the Littelfuse SVxx12xx series to avoid confusion with similar SCR packages. Cross-reference the component marking with the official part identification guide.
Selection Notes
Select this component when a surface mount SCR is required for high-temperature environments exceeding standard ratings. Compare the 12 A RMS current and 800 V blocking voltage against circuit requirements. Verify that the TO-251-3 footprint aligns with the PCB layout constraints and that the thermal management strategy supports the specified operating temperature range.
Part Context
This device belongs to the Littelfuse SVxx12xx series of thyristors. It shares the 12 A current rating with other members of the family but is distinguished by its specific voltage rating and surface mount packaging. The series is designed to provide reliable switching solutions for industrial and commercial power electronics applications requiring compact form factors.
Replacement Considerations
Direct substitutes may include the S8012DTP or SV8012VTP if pin compatibility and electrical parameters match. Verify that any replacement maintains the same TO-251-3 or compatible package type and meets the 800 V and 12 A specifications.
