9926A SOP-8 Dual N-Channel MOSFET - 20V / 6A Battery Protection (10-Pack)

The 9926A (also marked AO9926A) is a dual N-Channel enhancement-mode MOSFET in a SOP-8 surface-mount package, integrating two independent N-Channel MOSFETs rated at 20V / 6A with an ultra-low RDS(on) of 28m ohm. The dual-MOSFET configuration in a single SOP-8 package makes it the standard choice for Li-ion battery protection BMS circuits requiring both charge and discharge control MOSFETs.

Why Choose 9926A?

Dual MOSFET in SOP-8 - Two MOSFETs in one package; ideal for BMS charge/discharge control
28m ohm RDS(on) - Low conduction loss for efficient battery power delivery
6A Per Channel - Handles typical 1-2C discharge rates for 18650 and LiPo cells
20V Rating - Safe margin for 3.7V Li-ion and 7.4V 2S pack voltages
SOP-8 Package - Standard BMS PCB footprint; direct replacement for common BMS MOSFETs

Typical Applications

Single-cell Li-ion/LiPo BMS charge and discharge MOSFET
2S Li-ion battery protection circuit
Power bank battery protection module
E-cigarette and vape battery protection
Dual-channel load switch for power management
Bidirectional power switch for battery systems

FAQ

Q: Can 9926A replace DW01A + 8205A in a BMS? The 9926A replaces the 8205A dual MOSFET portion. The DW01A (or similar) BMS controller IC is still required to drive the MOSFET gates.

Q: What BMS IC is compatible with 9926A? DW01A, S-8261, FS312F-G, and most single-cell Li-ion BMS controller ICs. Connect CO to gate of charge MOSFET, DO to gate of discharge MOSFET.
