Overview
The LM336BMX-2.5/NOPB is a precision shunt voltage reference diode from the LM336 series, manufactured by Texas Instruments. It provides a nominal output voltage of 2.49 V with an initial accuracy of ±1%. The device operates in surface-mount SOIC-8 packages and supports a maximum shunt current of 10 mA. It features a temperature coefficient of 20 ppm/°C and functions within a commercial operating temperature range of 0°C to +70°C.
Feature Summary
- Provides stable 2.49 V reference via two-terminal shunt regulation
- Maintains high precision with ±1% initial accuracy
- Ensures thermal stability through low temperature coefficient
Applications
- Precision analog-to-digital converter (ADC) references
- Data acquisition system voltage standards
- Battery-powered instrumentation circuits
Procurement Notes
Verify the specific suffix against the manufacturer's latest datasheet to confirm package type and electrical tolerances. Ensure the component meets RoHS compliance requirements for your assembly process. Cross-reference the ordering part number with official distributor catalogs to avoid substitution errors during procurement.
Selection Notes
Select this component when a compact surface-mount solution is required for fixed 2.5 V applications. It is suitable for designs needing ±1% accuracy without external trimming. Consider the SOIC-8 footprint constraints and the 0°C to +70°C operating range before finalizing the schematic.
Part Context
This part belongs to the LM336 family of two-terminal voltage references, which are direct replacements for Zener diodes in many regulator applications. The 'B' designation typically indicates improved accuracy grades compared to standard variants. The 'MX' suffix denotes the small-outline integrated circuit package configuration used in modern PCB assemblies.
Replacement Considerations
LM336M-2.5/NOPB offers identical electrical specifications in an SOIC-8 package. LM336Z-2.5/LFT7 provides similar performance but utilizes a TO-92 through-hole package.
