Overview
The FSA4159L6X_F113 is a low-voltage Single-Pole Double-Throw (SPDT) analog switch fabricated with sub-micron CMOS technology. It operates over a wide supply voltage range of 1.65 V to 5.50 V and features ultra-low on-resistance, typically 1 Ω at 4.5 V VCC. The device supports a continuous switch current of 200 mA and offers fast switching speeds with turn-on times as low as 1 ns and turn-off times down to 1 ns at higher voltages. It includes power-off isolation capabilities and break-before-make enable circuitry. The component is housed in a space-saving MicroPak-6 surface-mount package.
Feature Summary
- Ultra-low on-resistance for minimal signal loss
- Power-off isolation when supply voltage is zero
- Low quiescent current compatible with baseband processor I/Os
- Break-before-make operation prevents signal shorting
Applications
- Cellular phones
- Portable media players
- Personal Digital Assistants (PDAs)
Procurement Notes
Verify the specific ordering suffix L6X corresponds to the MicroPak-6 package and 5000-unit tape and reel shipping configuration. Confirm RoHS compliance and lead-free status requirements against current manufacturing standards before finalizing procurement specifications.
Selection Notes
Select this component for applications requiring low voltage operation between 1.65 V and 5.50 V. Ensure the required on-resistance flatness and leakage currents meet system specifications within the -40°C to +85°C operating temperature range. Verify that the MicroPak-6 package dimensions fit the available PCB real estate.
Part Context
This part belongs to the FSA4159 series of low-voltage SPDT analog switches manufactured by onsemi. It is designed to replace older technologies in portable electronics where space and power consumption are critical constraints. The device utilizes proprietary sub-micron CMOS processes to achieve high performance in a compact footprint.
Replacement Considerations
Direct pin-compatible replacements include the FSA4159P6X variant, which shares identical electrical characteristics but utilizes an SC-88 (SC-70 6 Lead) package instead of the MicroPak-6 form factor. Verify mechanical clearance and soldering profile compatibility when substituting packages.
