FSA3357K8X

Overview

The FSA3357K8X is a dual SPDT analog switch manufactured by onsemi, designed for low-voltage signal routing applications. It operates within a supply voltage range of 1.65 V to 5.5 V and features a maximum on-resistance (Ron) of 1.3 Ohms at 5 V. The device supports bidirectional current flow with a continuous DC switch current rating of 200 mA. Key electrical parameters include a maximum leakage current of 500 nA and propagation delays of 35 ns (on) and 15 ns (off). It is housed in a MicroPak-10 surface-mount package.

Feature Summary

Ultra-low on-resistance ensures minimal signal attenuation in high-fidelity audio and video paths.
Bidirectional switching capability allows flexible signal routing without direction constraints.
Low power consumption design supports battery-operated portable devices.
Compact MicroPak-10 packaging facilitates space-constrained board layouts.

Applications

Portable multimedia devices for audio/video signal switching
Mobile phones and tablets for antenna and sensor routing
Consumer electronics requiring low-voltage signal multiplexing

Procurement Notes

Verify the specific ordering suffix K8X against the manufacturer's official datasheet to confirm package type and tape-and-reel specifications. Ensure compatibility with RoHS3 and REACH regulations as stated in the product documentation. Cross-reference the DigiKey part number 512-FSA3357K8XTR2G or equivalent distributor codes for accurate sourcing. Confirm availability status directly with authorized distributors as lifecycle status may vary.

Selection Notes

Select this component when a dual SPDT configuration is required for signals below 5.5 V. The 1.3 Ohm Ron is suitable for applications demanding low insertion loss. Compare propagation delays against system timing requirements. Ensure the operating temperature range meets the application environment. Verify that the MicroPak-10 footprint aligns with the PCB layout constraints.

Part Context

The FSA3357K8X belongs to onsemi's FSA series of analog switches, which are optimized for low-voltage, low-power applications. This series is commonly used in portable electronics where signal integrity and power efficiency are critical. It serves as a replacement for older discrete switching solutions, offering integrated functionality in a compact form factor.

Replacement Considerations

Publicly confirmed substitute part numbers for the FSA3357K8X were not found in the provided source material. Consult the manufacturer's official substitution guide or contact technical support for verified alternatives. Do not assume pin-to-pin compatibility with other analog switches without verifying electrical parameters and package dimensions.
