Overview
The NSVBAS21TMR6T2G is a triple high voltage switching diode manufactured by onsemi. It integrates three independent rectifier diodes within a single surface-mount package, specifically the SC-74 (SOT-363) configuration. The device utilizes silicon planar technology and is designed for general-purpose switching applications requiring compact board space. Key electrical characteristics include a maximum repetitive peak reverse voltage of 250V and a continuous forward current rating of 200mA per element. The component features a low forward voltage drop of approximately 1V at rated current, ensuring efficient power handling in signal processing circuits.
Feature Summary
- Integrates three independent high-voltage switching diodes in a compact surface-mount package
- Utilizes silicon planar technology for reliable general-purpose rectification
- Designed for applications requiring small form factor and high voltage isolation
Applications
- General-purpose signal switching circuits
- High-voltage rectification in compact electronic devices
- Protection circuits requiring multiple isolated diode paths
Procurement Notes
Verify the specific suffix TMR6T2G against official onsemi documentation to confirm packaging details and tape-and-reel specifications. Ensure compatibility with automated pick-and-place equipment regarding the SC-74 footprint. Cross-reference the datasheet for moisture sensitivity level and recommended soldering profiles to prevent assembly defects during reflow processes.
Selection Notes
Select this component when a design requires three separate high-voltage switching functions within a limited PCB area. Compare the 250V reverse voltage rating against circuit peak inverse voltage requirements. Evaluate the thermal performance and forward voltage characteristics relative to alternative dual or single diode configurations to ensure optimal efficiency and space utilization in the final assembly.
Part Context
This part belongs to the BAS21 series of triple high-voltage switching diodes from onsemi. The series is engineered for applications demanding robust performance in minimal footprints. The NSVBAS21 variant specifically addresses needs for multi-channel rectification or logic isolation where standard discrete diodes would consume excessive board real estate, offering a consolidated solution for modern compact electronics.
Replacement Considerations
Consult official cross-reference lists for verified substitutes such as the NSVBAS21TMR6T1G. Confirm pinout compatibility and electrical parameter equivalence before substitution. Verify that any alternative maintains the same SC-74 package dimensions and lead configuration to ensure mechanical fit without redesigning the PCB layout.
