Overview
The TPW3111-S5TR is a low voltage Single Pole/Single Throw (SPST) analog switch manufactured by 3PEAK. It operates within a supply voltage range of 1.65V to 5.5V and features a typical on-state resistance of 1Ω at Vs = 4.5V. The device provides a bandwidth of 100 MHz with fast switching times, specifically tON = 40 ns and tOFF = 15 ns. It incorporates break-before-make switching logic and functions reliably across an operating temperature range of –40°C to 125°C.

Procurement Notes
Verify the specific package marking information for the SOT23-5 variant before procurement. Confirm that the ordering suffix matches the required transport media quantity and ensure the component meets the specified MSL rating requirements for your assembly process.
Selection Notes
Select this component when a single-channel analog switch with minimal signal attenuation is required. Ensure the application voltage stays within the 1.65V to 5.5V limit. Consider the 1Ω resistance for high-current paths and verify that the 100 MHz bandwidth aligns with the signal frequencies in use.
Part Context
The TPW3111 is part of 3PEAK's portfolio of low voltage analog switches designed for portable and battery-operated applications. It serves as a cost-effective solution for signal routing where low power consumption and small footprint are critical design constraints.
Replacement Considerations
Refer to the manufacturer's Switch Select Table for compatible alternatives. The TPW3115 offers similar SPST functionality but with higher on-resistance characteristics suitable for different load conditions.
FAQ
What is the maximum current handling capability of the TPW3111?
The absolute maximum switch current rating is 200mA.
How does the control input interface work?
The Select pin controls the switch state; a High logic level turns the switch On, while a Low logic level turns it Off.
Is the TPW3111 suitable for audio applications?
Yes, the datasheet explicitly lists Audio Signal Routing as a primary application due to its low distortion and high bandwidth.
