Single FETs, MOSFETs Procurement Notes

Verify the specific package suffix matches the required form factor: 'T' indicates TO-220, while 'B' indicates TO-263 D2PAK. Confirm RoHS compliance status as the 'L' suffix denotes Halogen-free construction. Ensure the design accounts for the consumer market qualification level specified in the datasheet limitations.

Single FETs, MOSFETs Selection Notes

Select this component for low-current switching tasks requiring moderate voltage blocking. The 0.9Ω on-resistance limits suitability for high-efficiency high-power converters. Verify thermal management requirements against the junction-to-case resistance values provided for the chosen package type to ensure safe operating area compliance.

Single FETs, MOSFETs Part Context

This part belongs to the AOT4S60 family, which shares identical electrical characteristics across different physical packages. The AOB4S60 variant utilizes the TO-263 D2PAK surface-mount package, while the AOT4S60 uses the through-hole TO-220 package. All variants share the same die and performance specifications.

Single FETs, MOSFETs Replacement Considerations

Direct pin-compatible replacements include the AOB4S60L (TO-263 package) and AOTF4S60L (TO-220F package). Cross-brand replacements must match the 600V/650V VDS rating, 4A ID current, and 0.9Ω RDS(on) maximums.

Single FETs, MOSFETs FAQ

What is the difference between AOT4S60L and AOB4S60L?

The primary difference is the package style. AOT4S60L is housed in a TO-220 through-hole package, whereas AOB4S60L is packaged in a TO-263 D2PAK surface-mount configuration. Electrical parameters remain identical.

Is the AOT4S60L qualified for automotive or critical life support applications?

No. The product is designed and qualified specifically for the consumer market. Applications as critical components in life support devices or systems are not authorized by the manufacturer.
