FSA1156P6X

Analog Switches, Multiplexers, Demultiplexers Overview

The onsemi FSA1156P6X is a single-pole single-throw (SPST) analog switch IC designed for low-voltage applications. It operates within a supply voltage range of 1.65 V to 5.5 V and features a maximum on-resistance of 900 mOhms. The device supports a DC switch current of 200 mA with a maximum power dissipation of 180 mW. Electrical performance includes a maximum turn-on time of 20 ns and a maximum turn-off time of 30 ns. It functions reliably across an operating temperature range from -40°C to +85°C. The component is housed in a compact SC-70-6 surface-mount package.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix to confirm the SC-70-6 package configuration, as other suffixes may indicate different packaging or variants. Confirm RoHS compliance status through official documentation before integration. Check current lifecycle status, as availability may vary by region and distributor. Ensure design compatibility with the specified 1.65 V to 5.5 V supply range requirements.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a single-channel analog switch is required for low-voltage signal routing. The SC-70-6 package offers space efficiency for dense PCB layouts. Consider the 900 mOhm on-resistance limit for signal integrity requirements. Verify that the 200 mA DC switch current meets load demands. Compare against alternatives if higher channel counts or different package styles are needed.

Analog Switches, Multiplexers, Demultiplexers Part Context

The FSA1156P6X belongs to the FSA1156 series of analog switches from onsemi. This series focuses on low-power, low-voltage applications suitable for portable devices. The P6X suffix specifically denotes the SC-70-6 surface-mount package variant.
