Overview
The LM336BM-5.0/NOPB is a precision shunt voltage reference diode manufactured by Texas Instruments, continuing the legacy of the National Semiconductor LM336 series. It operates as a low temperature coefficient 5.0V Zener diode with a dynamic impedance of 0.6 ohms. The device features an adjustable output range from 4V to 6V and supports a wide operating current range. It is housed in an SOIC-8 surface-mount package and offers initial accuracy of ±1%.
Feature Summary
- Provides a stable 5.0V reference voltage with low temperature coefficient characteristics
- Features a third terminal allowing easy trimming of reference voltage and temperature drift
- Operates effectively as both positive and negative voltage references due to shunt regulator topology
Applications
- Precision digital voltmeters requiring stable low-voltage references
- Power supply circuits needing accurate voltage regulation
- Operational amplifier biasing and reference circuits
Procurement Notes
Verify that the ordering suffix /NOPB confirms lead-free and RoHS compliance status according to the manufacturer's latest documentation. Confirm the specific package variant matches the required surface-mount footprint for PCB integration. Ensure the supplier provides valid traceability data for the component lot.
Selection Notes
Select this component when a surface-mount solution is required for precision voltage referencing applications. The SOIC-8 package facilitates automated assembly compared to through-hole alternatives. Consider the 0.6 ohm dynamic impedance and trimmable nature for high-accuracy designs where standard Zener diodes may introduce excessive noise or drift.
Part Context
This part belongs to the LM336 family of monolithic IC voltage references. Originally developed by National Semiconductor, the product line is now managed by Texas Instruments following their acquisition. The LM336 series is widely recognized for its reliability and precision in industrial and commercial instrumentation applications.
Replacement Considerations
Direct substitutes include LM336BMX-5.0/NOPB and LM336BDT-2.5 (for different voltage). Verify pinout compatibility and thermal performance before substitution.
