Overview
The FSA66P5 is a single-channel, single-pole single-throw (SPST) normally open analog switch 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 a maximum operating frequency with a turn-on time of 4.5 ns and a turn-off time of 5 ns. It is housed in a SC-70-5 surface-mount package and functions reliably across an extended temperature range from -40°C to +85°C. The component draws a maximum supply current of 10 µA and dissipates up to 150 mW of power.
Feature Summary
- Low-voltage operation compatible with modern portable electronics
- Ultra-high-speed switching for signal integrity
- Compact surface-mount packaging for space-constrained designs
Applications
- Portable consumer electronics such as mobile phones and tablets
- Battery-powered devices requiring low standby current
- Signal routing in multimedia interfaces
Procurement Notes
Verify the specific suffix designation when ordering, as the base model may correspond to different package variants like the SC-70-5 or TSSOP configurations found in distributor databases. Confirm RoHS compliance status and lead-free specifications directly with the manufacturer or authorized distributors prior to procurement. Check for end-of-life notices or production change notifications that may affect long-term availability.
Selection Notes
Select this component for applications requiring a single analog switch with low on-resistance and fast switching speeds. Ensure the system supply voltage remains within the 1.65 V to 5.5 V range. Consider the thermal dissipation limits of 150 mW when designing the PCB layout. Verify that the required package type matches the available suffixes for the FSA66P5 series.
Part Context
The FSA66P5 belongs to the FSA66 series of low-voltage ultra-high-speed analog switches from onsemi. This family is designed for high-performance signal switching in portable devices. The part shares functional similarities with other single SPST switches but is distinguished by its specific voltage range and switching speed characteristics optimized for low-power applications.
Replacement Considerations
Potential substitutes include the NC7SZ66 and MC74VHC1G66, which are also single SPST normally open analog switches. Verify pin compatibility and electrical parameters such as on-resistance and supply voltage range before substitution.
