FSA66M5

Overview

The FSA66M5 is a single-channel, normally open analog switch IC manufactured by onsemi. It operates within a supply voltage range of 1.65 V to 5.5 V and features a maximum on-resistance of 7 Ohms. The device supports high-speed switching with a maximum turn-on time of 4.5 ns and a maximum turn-off time of 5 ns. It is housed in an SOT-23-5 surface-mount package and is rated for operation between -40°C and +85°C. The component draws a maximum supply current of 10 µA and dissipates up to 200 mW of power.

Feature Summary

Single SPST configuration for signal routing
Low on-resistance for minimal signal loss
High-speed switching capability
Low power consumption design

Applications

Portable consumer electronics
Audio signal path switching
Data acquisition systems

Procurement Notes

Verify the manufacturer status as the component is listed as obsolete or end-of-life. Confirm availability through authorized distributors or secondary market suppliers. Ensure RoHS compliance documentation is obtained prior to procurement. Check for alternative packages or pin-compatible replacements if long-term supply is required.

Selection Notes

Select this component when a low-voltage, single-channel analog switch is required. Verify that the 7 Ohm on-resistance meets the application's signal integrity requirements. Ensure the operating temperature range covers the intended environment. Consider the SOT-23-5 package size for space-constrained designs.

Part Context

The FSA66M5 belongs to the family of low-voltage analog switches from Fairchild Semiconductor (now onsemi). It is designed for applications requiring efficient signal routing in portable devices. The part is distinct from higher-channel-count switches and offers a compact solution for single-path switching needs.

Replacement Considerations

Check for pin-compatible alternatives from onsemi or other manufacturers. Verify electrical parameters such as on-resistance and supply voltage range match the original design requirements.
