Overview
The LM136AH-5.0/883/MPGD is a monolithic precision shunt voltage reference diode manufactured by Texas Instruments. It provides a stable 5.0V reference with a low temperature coefficient of 20 PPM/C and an initial accuracy of 1%. The device operates within a wide current range from 600 uA to 10 mA, featuring a dynamic impedance of 0.6 Ohms. Designed for high-reliability applications, it supports operation temperatures from -55 C to +125 C and utilizes a TO-92 package.
Feature Summary
- Provides a precise 5.0V shunt reference with low temperature drift
- Features a third terminal for easy trimming of voltage and temperature coefficient
- Offers fast startup times and wide operating current range
- Designed for high reliability in military and aerospace environments
Applications
- Digital voltmeters requiring precise voltage references
- Power supply circuits needing stable regulation
- Operational amplifier biasing networks
- Military and aerospace electronic systems
Procurement Notes
Verify the specific suffix /883/MPGD indicates compliance with MIL-PRF-38534 or similar military standards. Confirm that the component meets all required environmental testing specifications for your application. Ensure the supplier provides valid traceability documentation. Check for any special handling requirements due to the ceramic or metal package construction typical of this series.
Selection Notes
Select this component when a highly stable 5.0V reference is required in harsh environments. Consider the third terminal feature if active trimming of temperature drift is necessary. Evaluate the 0.6 Ohm dynamic impedance against load regulation needs. Ensure the operating temperature range of -55 C to +125 C aligns with system constraints.
Part Context
This part belongs to the LM136/LM336 family of precision shunt voltage references. These devices are widely used as low-temperature-coefficient Zener diodes. The LM136 variant typically offers higher performance and reliability compared to commercial grades, suitable for demanding industrial and defense applications.
Replacement Considerations
LM336Z-5.0/NOPB is a commercial grade equivalent but lacks military qualification. LM136H-5.0 may be a direct pin-compatible alternative within the same reliability class. Verify package dimensions and electrical tolerances before substitution.
