XS3A1T5157GMX

Overview

The Nexperia XS3A1T5157GMX is a low-ohmic single-pole double-throw (SPDT) analog switch housed in an XSON6 plastic package (SOT886). It operates on a single supply voltage ranging from 1.4 V to 4.3 V with a maximum power dissipation of 250 mW. The device features Schmitt trigger inputs for noise immunity and supports signals up to VCC. Key electrical parameters include a peak ON resistance of 0.9 Ω maximum at 4.3 V, a continuous switch current of 350 mA, and a maximum supply current of 150 nA. Dynamic characteristics specify a maximum enable time of 100 ns and a disable time of 80 ns across the operating temperature range of -40 °C to +125 °C.

Feature Summary

• Low threshold digital input allows control by 1.8 V logic levels while switching signals up to 4.3 V without external level translation.
• Break-before-make switching mechanism prevents signal overlap during channel transitions.
• High current handling capability supports continuous currents up to 350 mA under standard supply conditions.

Applications

• Mobile phone
• Tablet / Notebook
• Wearables

Procurement Notes

Verify the specific ordering suffix GMX against the manufacturer's official documentation to confirm the SOT886 (XSON6) package variant. Ensure that the selected component meets the required thermal derating specifications for total power dissipation above 74 °C. Confirm RoHS compliance status through the latest product data sheet before finalizing procurement orders.

Selection Notes

Select this component when designing circuits requiring low ON resistance and compatibility with 1.8 V logic controllers driving higher voltage analog signals. Verify that the application environment stays within the specified ambient temperature limits of -40 °C to +125 °C. Consider the XSON6 package dimensions if board space is constrained, as it offers a compact footprint for SPDT switching applications.

Part Context

The XS3A1T5157GMX belongs to the XS3A1T5157 series of low-ohmic analog switches manufactured by Nexperia. This series is designed for portable electronics where power consumption and signal integrity are critical. The GMX suffix specifically denotes the reel-packaged version of the SOT886 (XSON6) package variant, distinct from the GS (SOT1202) package option available in the same family.

Replacement Considerations

The datasheet lists the XS3A1T5157GS as an alternative package variant within the same functional family. No other cross-model substitutes are documented in the provided source material.
