LM336Z-2.5/LFT1

Overview

The LM336Z-2.5/LFT1 is a two-terminal voltage reference diode manufactured by Texas Instruments, originally part of the National Semiconductor portfolio. It provides a nominal output voltage of 2.49 V with a maximum of 2.59 V and a minimum of 2.39 V. The device operates within a temperature range of 0 °C to 70 °C and utilizes a TO-92 package with three pins. It functions as a shunt precision reference with an initial accuracy of 4% and a temperature coefficient of 20 PPM/°C. The component supports through-hole mounting and handles a maximum shunt current of 10 mA.

Feature Summary

Provides stable two-terminal voltage reference functionality
Features low dynamic impedance for precise regulation
Offers adjustable temperature coefficient via third terminal

Applications

Digital voltmeter references
Power supply voltage regulation
Operational amplifier circuit biasing

Procurement Notes

Verify manufacturer origin as Texas Instruments acquired National Semiconductor assets. Confirm RoHS compliance status and lead time requirements. Ensure the specific suffix /LFT1 matches the required reel or tape packaging configuration for automated assembly processes.

Selection Notes

Select this component when a fixed 2.5V reference is required in a TO-92 package. Consider the 4% initial accuracy and 20 PPM/°C temperature coefficient against application tolerance needs. Verify that the 10 mA maximum shunt current meets the circuit's power dissipation constraints.

Part Context

This device belongs to the LM336 series of precision shunt voltage references. It serves as a cost-effective alternative to Zener diodes, offering superior temperature stability and lower dynamic impedance. The TO-92 form factor allows for easy integration into legacy designs requiring through-hole technology.

Replacement Considerations

LM336Z-2.5/NOPB offers similar specifications with potentially different environmental compliance markings. LM236Z-2.5 provides industrial grade temperature range options. Verify pinout compatibility and thermal characteristics before substitution.
