LM336Z-5.0/NOPB

Overview

The LM336Z-5.0/NOPB is a precision shunt voltage reference diode from the LM336 series, manufactured by Texas Instruments. It provides a nominal reference voltage of 5.0 V with an initial accuracy of ±1%. The device operates in a TO-92-3 through-hole package and supports a shunt current range from 600 µA to 10 mA. It features a temperature coefficient of 20 ppm/°C and a dynamic impedance of 0.6 Ω. The component functions as a low-voltage reference suitable for applications requiring stable performance across a commercial operating temperature range of -40°C to +85°C.

Feature Summary

• Provides a precise 5.0 V reference voltage with ±1% initial tolerance
• Operates as a shunt regulator with wide working current range from 600 µA to 10 mA
• Features low dynamic impedance of 0.6 Ω for stable regulation
• Includes a third terminal for easy trimming to minimize temperature drift

Applications

• Digital voltmeters
• Power supply circuits
• Operational amplifier circuits

Procurement Notes

Verify the specific suffix NOPB indicates lead-free compliance and RoHS adherence when sourcing. Confirm the TO-92-3 package type matches your PCB footprint requirements. Ensure the operating environment stays within the specified -40°C to +85°C range. Check that the required shunt current remains between 600 µA and 10 mA for proper regulation. Validate that the 5.0 V output aligns with your system's reference needs.

Selection Notes

Select this component when a fixed 5.0 V precision reference is needed in a through-hole package. It is suitable for designs requiring ±1% accuracy without external trimming. Consider the 20 ppm/°C temperature coefficient for thermal stability requirements. Ensure the circuit can maintain the minimum 600 µA shunt current. This part is appropriate for general-purpose industrial applications rather than automotive use.

Part Context

The LM336Z-5.0/NOPB belongs to the LM336 family of precision shunt voltage references. These devices utilize a Zener diode structure with a low temperature coefficient. The NOPB suffix denotes a non-pb (lead-free) product compliant with RoHS standards. The TO-92 package offers a compact solution for through-hole mounting. This series is designed to replace standard Zener diodes where higher precision and lower dynamic impedance are required.

Replacement Considerations

LM336Z-5.0 is the direct predecessor without the NOPB suffix. LM336Z-5.0X is another variant within the same series. Verify pinout compatibility when substituting with other manufacturers' equivalents.
