Single FETs, MOSFETs Applications

Single FETs, MOSFETs Procurement Notes

Verify component authenticity through authorized distribution channels or certified distributors. Confirm that the specific marking code corresponds to the BSS123-F169 designation. Check for any obsolescence notices from onsemi, as this part may be discontinued. Ensure storage conditions comply with moisture sensitivity levels if applicable. Validate packaging integrity upon receipt to prevent damage to the small SOT-23 components.

Single FETs, MOSFETs Selection Notes

Select this component for low-current switching applications requiring logic-level gate drive compatibility. The 100V rating suits general-purpose signal switching rather than high-power loads. Consider the 170mA current limit when designing load circuits. The SOT-23 package offers space-efficient mounting for compact designs. Evaluate thermal management requirements given the low power dissipation limits inherent to this small-signal MOSFET.

Single FETs, MOSFETs Part Context

This component is part of onsemi's PowerTrench series, which focuses on efficient power switching solutions. The BSS123 variant specifically targets low-voltage, low-current applications where size and cost are critical factors. It serves as a discrete solution for signal routing and small load control in consumer electronics and industrial equipment.

Single FETs, MOSFETs Replacement Considerations

The BSS123-F169 is listed as obsolete and no longer manufactured by onsemi. Available substitutes include MFR recommended alternatives. Verify pinout compatibility and electrical parameters such as Vds, Id, and Rds(on) when selecting a replacement from the manufacturer's current portfolio.
