LM336BZ-2.5/NOPB

Overview

The LM336BZ-2.5/NOPB is a precision shunt voltage reference diode manufactured by Texas Instruments, belonging to the LM336 series. It provides a nominal reference voltage of 2.5 V with an initial accuracy of ±1%. The device utilizes a TO-92 three-pin through-hole package and operates within a temperature range of -40°C to +85°C. Key electrical specifications include a maximum shunt current of 10 mA, a minimum operating current of 600 µA, and a temperature coefficient of 20 ppm/°C. The input voltage range spans from 2.44 V to 2.54 V.

Feature Summary

• Provides stable 2.5 V reference output with high precision
• Operates as a two-terminal shunt regulator
• Compatible with standard through-hole mounting

Applications

• Precision analog-to-digital converter references
• Voltage monitoring circuits
• Battery-powered instrumentation

Procurement Notes

Verify the specific suffix 'NOPB' confirms lead-free compliance and RoHS status against the latest manufacturer datasheet. Confirm the 'B' grade designation corresponds to the required ±1% initial accuracy for your application. Ensure the TO-92 package dimensions match your PCB footprint requirements before finalizing procurement orders.

Selection Notes

Select this component when a fixed 2.5 V reference is required in a through-hole configuration. The ±1% accuracy and 20 ppm/°C temperature coefficient make it suitable for general-purpose precision applications. Compare against LM336M variants if surface-mount technology is preferred or if different accuracy grades are needed.

Part Context

This part belongs to the LM336 family of two-terminal voltage references, which are direct replacements for Zener diodes but offer superior stability. The LM336 series includes various voltage options and packages, with the LM336BZ specifically denoting the 2.5 V version in a TO-92 case.

Replacement Considerations

LM336BZ-2.5/LFT7 serves as a tape-and-reel alternative within the same series.
