PI5A3158BZAEX

Overview

The PI5A3158BZAEX is a dual high-bandwidth, fast single-pole double-throw (SPDT) CMOS switch manufactured by Diodes Incorporated. It operates within a wide supply voltage range of 1.65V to 5.5V and features a maximum ON resistance of 12Ω at 1.65V, 9Ω at 2.3V, and 6Ω at 4.5V. The device provides a -3dB bandwidth of 350MHz and achieves a propagation delay as low as 0.4ns at 5.0V. It utilizes a 12-pin TDFN package measuring 3mm×1mm and supports an extended industrial temperature range from -40°C to +85°C.

Feature Summary

Break-before-make switching mechanism prevents simultaneous switch enablement to eliminate signal disruption during transitions.
Rail-to-rail signal range capability allows for full voltage swing operation across the specified power supply limits.
Control input overvoltage tolerance ensures reliable logic interface even when control signals exceed the main supply voltage.

Applications

Cell Phones
PDAs
MP3 Players
Portable Instrumentation
Battery Powered Communications

Procurement Notes

Verify the specific ordering suffix 'X' confirms tape and reel packaging configuration. Confirm that the 'E' suffix indicates lead-free and green material compliance status. Ensure the component matches the 12-pin TDFN physical dimensions required for the target PCB layout. Validate that the manufacturer designation aligns with current corporate records following industry consolidations.

Selection Notes

Select this component for applications requiring dual SPDT analog switching with minimal signal distortion. The 350MHz bandwidth supports high-frequency data lines where low insertion loss is critical. Verify that the 12Ω maximum on-resistance at lower voltages meets the current handling requirements of the specific circuit path.

Part Context

This part belongs to the PI5A3158 family of low-voltage analog switches designed for portable electronics. It serves as a bus switch or analog multiplexer alternative in space-constrained designs. The device integrates two independent SPDT channels into a compact footprint suitable for modern mobile and handheld devices.
