Overview
The AOB2146L is a 40V N-Channel AlphaSGT™ Trench Power MOSFET manufactured by Alpha & Omega Semiconductor Inc. It utilizes advanced trench technology to achieve low on-resistance and gate charge. The device features a maximum drain-source voltage of 40V, a continuous drain current of 105A at VGS=10V, and a static drain-source on-resistance of less than 2.8mΩ at VGS=10V and 3.9mΩ at VGS=4.5V. Packaged in TO-263 (D2PAK) for surface mount applications, it supports high-efficiency power switching.
Feature Summary
- Utilizes AlphaSGT™ Trench Power technology for optimized performance
- Features low static drain-source on-resistance across standard drive voltages
- Designed with low gate charge characteristics for efficient switching
- Subjected to 100% testing for Unclamped Inductive Switching (UIS) capability
Applications
- DC Motor Driver circuits
- Synchronous Rectification in DC/DC Converters
- Synchronous Rectification in AC/DC Converters
Procurement Notes
Verify the specific ordering suffix 'L' corresponds to the TO-263 Tape & Reel packaging configuration as documented in official manufacturer catalogs. Confirm compliance with RoHS and Halogen-Free standards required for the target assembly process. Ensure thermal management design accounts for the junction-to-case resistance values provided in the datasheet to maintain safe operating temperatures during operation.
Selection Notes
Select this component when a low-voltage, high-current N-channel solution is required for synchronous rectification or motor control. The TO-263 package offers robust thermal dissipation capabilities suitable for power stages. Evaluate the low RDS(ON) specifications against system efficiency targets and ensure the gate drive voltage aligns with the optimal conduction characteristics defined in the electrical parameters.
Part Context
This part belongs to the AlphaSGT™ family of power MOSFETs from Alpha & Omega Semiconductor Inc., designed for high-performance power management applications. The AOB2146L specifically addresses the need for low conduction losses in 40V systems. It shares technological foundations with other devices in the series but is distinct in its voltage rating and current handling capacity within the TO-263 form factor.
Replacement Considerations
Cross-reference with the AOT2146L for identical electrical performance if through-hole mounting is preferred instead of surface mount. Verify pinout compatibility and thermal resistance differences between the TO-263 and TO-220 packages before substituting.
