LM336BM-5.0/NOPB

Overview

The LM336BM-5.0/NOPB is a precision shunt voltage reference diode from the LM336 series, manufactured by Texas Instruments. It provides a nominal 5.0V reference output with an initial accuracy of ±1%. The device operates within a temperature range of -40°C to +85°C and features a low temperature coefficient of 20 ppm/°C. Designed for through-hole mounting in an 8-pin SOIC package, it supports a maximum shunt current of 10mA and a minimum operating current of 600µA. Key electrical parameters include a dynamic impedance of 0.6Ω and a load regulation of 10mV.

Feature Summary

• Provides stable 5.0V reference using low temperature coefficient Zener technology
• Offers high initial accuracy with ±1% tolerance specification
• Supports wide operating current range from 600µA to 10mA
• Enables easy trimming for minimal temperature drift via third terminal

Applications

• Precision analog-to-digital converter references
• Digital voltmeter circuits
• Operational amplifier biasing networks
• Power supply regulation monitoring

Procurement Notes

Verify the specific suffix 'BM' indicates the 8-pin SOIC package variant distinct from the TO-92 'Z' version. Confirm the 'NOPB' designation ensures lead-free and RoHS compliance status. Cross-reference the manufacturer datasheet to validate the exact pinout configuration for surface-mount assembly. Ensure the selected component matches the required thermal performance specifications for the intended application environment.

Selection Notes

Select this component when a fixed 5.0V reference is required in a surface-mount format. The 8-pin SOIC package allows for compact circuit board designs compared to through-hole alternatives. Consider the ±1% initial accuracy and 20 ppm/°C temperature coefficient for applications demanding moderate precision. Verify that the 10mA maximum shunt current meets the power dissipation requirements of the target circuit design.

Part Context

This part belongs to the LM336 family of adjustable and fixed shunt voltage references. While the standard LM336Z is available in a TO-92 package, the LM336BM variant utilizes an 8-pin SOIC footprint. This family serves as a cost-effective alternative to more complex voltage regulator ICs for simple reference applications requiring stability over temperature variations.

Replacement Considerations

• LM336M-5.0/NOPB
• LM336BMX-5.0/NOPB

FAQ

What is the purpose of the third terminal on the LM336?

The third terminal allows for external trimming to minimize temperature drift and adjust the reference voltage slightly above or below the nominal value.

How does the LM336BM differ from the LM336Z?

The primary difference is the package type; the LM336BM uses an 8-pin SOIC surface-mount package, whereas the LM336Z typically uses a TO-92 through-hole package.
