Single FETs, MOSFETs Selection Notes

Select this component when a small-form-factor N-channel MOSFET with high voltage tolerance is required. The 100 V rating provides headroom for higher voltage environments compared to lower-rated alternatives. Consider the 190 mA current limit for low-power switching tasks rather than high-current power delivery applications.

Single FETs, MOSFETs Part Context

This part belongs to the BSS119 series of single N-channel MOSFETs from Infineon Technologies. The series is designed for general-purpose switching applications where compact size and automotive qualification are prioritized. The specific variant NH7978XTSA1 denotes the particular binning and packaging configuration within this product line.

Single FETs, MOSFETs Replacement Considerations

Cross-reference with other BSS119 variants such as BSS119NH6327XTSA1 for pin-compatible alternatives. Verify that substitute components meet the same AEC-Q100 qualification and SOT-23-3 package dimensions to ensure direct replacement without board redesign.
