KA336Z25BU

Overview

The KA336Z25BU is a precision shunt voltage reference manufactured by onsemi, housed in a TO-92-3 through-hole package. It provides a fixed nominal output voltage of 2.49V with an initial accuracy of ±1%. The device operates within a temperature range of 0°C to +70°C and supports a maximum shunt current of 10 mA, with a minimum operating current of 600 µA. Classified under PMIC - Power Management ICs, it serves as a stable reference source for analog circuits requiring precise voltage regulation.

Feature Summary

• Provides a fixed 2.49V reference output with high initial accuracy
• Operates as a shunt regulator with low minimum current requirements
• Designed for through-hole mounting in compact TO-92 packages

Applications

• Precision analog circuit voltage references
• Power supply monitoring systems
• Data acquisition signal conditioning

Procurement Notes

Verify the specific suffix 'BU' against the official datasheet to confirm packaging and tape/reel specifications. Confirm RoHS compliance status directly from the manufacturer's documentation. Ensure the TO-92-3 lead configuration matches the target PCB footprint design requirements before finalizing procurement.

Selection Notes

Select this component when a fixed 2.49V reference is required rather than the adjustable LM336 variant. Consider the ±1% tolerance for applications needing tighter initial accuracy compared to standard versions. Evaluate the thermal performance within the 0°C to +70°C range against the system's environmental operating conditions.

Part Context

This part belongs to the KA336/LM336 family of shunt voltage references. It shares functional similarities with the LM336Z25X but offers a fixed output voltage instead of programmability. The device is categorized under onsemi's power management integrated circuits portfolio.

Replacement Considerations

The LM336Z25X is a related adjustable version within the same family. Verify pinout compatibility and electrical parameter differences before substitution.
