LM336BDG4-2-5

Overview

The LM336BDG4-2.5 is a precision shunt voltage reference diode manufactured by Texas Instruments, belonging to the LM336 series. It provides a nominal output voltage of 2.49 V with an initial accuracy of ±2%. The device operates within a temperature range of -40°C to +85°C and features a temperature coefficient of 20 ppm/°C. Designed for surface-mount applications, it utilizes an 8-SOIC package. The component supports a maximum shunt current of 10 mA and requires a minimum operating current of 400 µA to maintain regulation.

Feature Summary

• Provides stable 2.49 V reference via shunt topology
• Ensures high precision with ±2% initial accuracy
• Operates reliably across extended industrial temperatures

Applications

• Precision analog-to-digital converter references
• Portable battery-powered instrumentation
• Temperature measurement systems

Procurement Notes

Verify the specific suffix 'DG4' indicates lead-free composition and RoHS compliance as per manufacturer standards. Confirm the package type matches the 8-SOIC footprint required by the design. Ensure the ordering quantity aligns with standard reel sizes if tape-and-reel delivery is specified. Cross-reference the exact part number against the latest datasheet to confirm pinout compatibility.

Selection Notes

Select this component when a precise 2.49 V reference is required in a compact surface-mount format. The ±2% tolerance suits applications demanding higher accuracy than standard zener diodes but does not require ultra-low drift specifications. Consider the 10 mA current capability for driving moderate loads or biasing subsequent stages without external amplification.

Part Context

This device is part of the LM336 family of integrated reference circuits, which are widely used as low-cost, high-performance shunt regulators. The LM336 series serves as a direct replacement for traditional zener diodes in many voltage reference applications, offering superior temperature stability and lower dynamic impedance compared to discrete solutions.

Replacement Considerations

The LM336DR-2.5 is a confirmed substitute part number within the same product line.
