FDS6898A

FET, MOSFET Arrays Overview

The FDS6898A is a dual N-channel logic level MOSFET manufactured by onsemi, utilizing the PowerTrench process. It features a SO-8 surface-mount package with two independent channels. Key electrical parameters include a drain-source voltage (V_DSS) of 20 V and a continuous drain current (I_D) of 9.4 A. The static drain-source on-resistance (R_DS(on)) is specified at 14 mΩ maximum when V_GS = 4.5 V and I_D = 9.4 A, and 18 mΩ maximum when V_GS = 2.5 V and I_D = 8.3 A. The device has a gate-source voltage rating of ±12 V and operates within a junction temperature range of -55°C to +150°C.

FET, MOSFET Arrays Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm datasheet revision status as the product may be obsolete. Ensure proper handling procedures are followed during storage and assembly to prevent electrostatic discharge damage to the gate oxide layer.

FET, MOSFET Arrays Selection Notes

Select this component for designs requiring low R_DS(on) at logic-level gate voltages. Evaluate thermal dissipation requirements based on the specific PCB copper pad area, as thermal resistance varies significantly between minimum pads and larger mounting areas. Consider the total gate charge for driver capability assessment.

FET, MOSFET Arrays Part Context

This component belongs to the PowerTrench family of MOSFETs developed by Fairchild Semiconductor, which was later acquired by onsemi. The part number indicates a dual N-channel configuration. Similar parts in the series include the FDS6892AZ and FDS6900S, which offer different voltage and current ratings within the same package style.

FET, MOSFET Arrays Replacement Considerations

Check for equivalent dual N-channel MOSFETs in SO-8 packages with compatible V_DSS and R_DS(on) specifications. Verify pinout compatibility before substitution. Note that the original manufacturer Fairchild Semiconductor is now part of onsemi.
