XS3A1T3157GMX

Overview

The Nexperia XS3A1T3157GMX is a low-ohmic single-pole double-throw analog switch housed in an XSON6 (SOT886) package. It operates on a single supply voltage ranging from 1.4 V to 4.3 V and features a digital select input (S), two independent inputs/outputs (Y1, Y2), and a common port (Z). The device supports signals with amplitudes up to VCC and includes Schmitt trigger action for noise immunity. Key electrical parameters include a maximum ON resistance of 0.9 Ω at -40 °C to +125 °C, a maximum OFF-state leakage current of ±500 nA, and a maximum supply current of 7 μA. Dynamic characteristics specify a maximum enable time of 120 ns and a disable time of 90 ns across the full temperature range.

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 operating conditions.
• Robust ESD protection meets high standards including HBM class 3B exceeding 8000 V and IEC61000-4-2 contact discharge exceeding 8000 V.

Applications

• Mobile phone signal routing
• Tablet and notebook peripheral switching
• Wearable device power and data management

Procurement Notes

Verify the ordering suffix GMX corresponds to the SOT886 (XSON6) package variant when sourcing. Confirm that the required supply voltage and signal amplitude remain within the 1.4 V to 4.3 V operational limits. Ensure thermal derating guidelines are followed if power dissipation exceeds 250 mW at ambient temperatures above 74 °C.

Selection Notes

Select this component for designs requiring minimal signal attenuation due to its very low ON resistance and flatness. It is suitable for applications where eliminating logic level translation circuits is necessary to reduce board space. Verify that the required switching speed aligns with the specified enable and disable times for the target supply voltage.

Part Context

This part belongs to the XS3A1T3157 family of low-ohmic analog switches manufactured by Nexperia. The GMX suffix indicates the specific XSON6 (SOT886) surface-mount package configuration. It serves as a compact solution for multiplexing and demultiplexing tasks in portable electronics where space constraints and low power consumption are critical design factors.

Replacement Considerations
