Overview
The AOB9N70L is a surface-mount N-channel MOSFET from the AOT(B)9N70 family, housed in a TO-263 (D2PAK) package. It features a drain-source voltage of 700V and a continuous drain current of 9A at 25°C case temperature. The device guarantees an on-resistance of less than 1.2 ohms at VGS=10V and ID=4.5A. Key electrical parameters include a gate threshold voltage ranging from 3V to 4.5V, a total gate charge of up to 35nC, and input capacitance up to 1630pF. Thermal characteristics specify a junction-to-case resistance of 0.53°C/W and power dissipation of 5.8W at 25°C.
Feature Summary
- Advanced high-voltage MOSFET process designed for robust performance in AC-DC applications
- Guaranteed avalanche capability with 100% UIS testing
- Low on-resistance and reduced gate charge for efficient switching
- High peak diode recovery dv/dt rating
Applications
- Offline power supply designs

Procurement Notes
Verify the specific ordering suffix 'L' corresponds to the Green Tape & Reel packaging variant as listed in the datasheet. Confirm that the component meets RoHS standards and REACH requirements before integration. Ensure the procurement channel provides original manufacturer documentation to validate authenticity and revision status.
Selection Notes
Select this component for designs requiring high voltage blocking capabilities in a surface-mount form factor. Evaluate thermal management strategies based on the specified junction-to-case resistance. Consider the guaranteed avalanche energy ratings if the application involves inductive load switching or potential transient overvoltage conditions.
Part Context
This part belongs to the AOT(B)9N70 series, which includes through-hole variants like AOT9N70 and AOTF9N70. All variants share identical electrical specifications but differ in physical packaging and mounting style. The AOB9N70L specifically utilizes the TO-263 D2PAK package optimized for automated surface-mount assembly processes.
Replacement Considerations
Direct replacements within the same electrical specification are available in different packages, such as AOT9N70 or AOTF9N70L. Verify pinout compatibility and thermal pad dimensions when substituting between package types.
