Product details
Overview
LM136AH-5.0/883 from Texas Instruments is a precision 5.0V shunt voltage reference diode in a hermetically sealed TO-metal-can package, rated for −55°C to +125°C operation, with 4.93V to 5.02V initial breakdown voltage (at 1 mA), 1.6Ω dynamic impedance, and ±36 mV temperature stability over full military temperature range - used in high-reliability power supply calibration, analog-to-digital converter references, and aerospace instrumentation.
For engineers reviewing the LM136AH-5.0/883 datasheet, LM136AH-5.0/883 pinout, LM136AH-5.0/883 application, or LM136AH-5.0/883 equivalent, this page delivers verified military-grade specifications, validated trim-adjustable architecture, TO-46 package mechanical data, and direct alternatives for radiation-tolerant reference design.
Technical Context
The LM136AH-5.0/883 implements a monolithic shunt regulator architecture with three-terminal configuration (Anode, Cathode, Adjust), enabling precise 5.0V output via external potentiometer trimming while maintaining low temperature coefficient. Its 0.6 mA to 10 mA operating current range and 1.6Ω dynamic impedance support stable regulation under varying load conditions.
It operates as a low-temperature-coefficient zener replacement with adjustable breakdown (4V–6V) and independent temperature coefficient tuning using series diodes - confirmed per MIL-STD-883 Group A testing across −55°C, +25°C, and +125°C subgroups, with 150°C max junction temperature and 46°C/W junction-to-case thermal resistance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reference Voltage | 4.93V to 5.02V at 1 mA (LM136A grade, ensures tighter initial accuracy vs standard LM136) |
| Dynamic Impedance | 1.6Ω - enables low-output-noise regulation with minimal voltage shift under load transients |
| Temp Stability | ±36 mV over −55°C to +125°C - meets MIL-STD-883 requirements for high-reliability systems |
| Operating Current | 0.6 mA to 10 mA - supports biasing from ultra-low-power sensors to high-current reference buffers |
| Junction Temp Max | 150°C - allows operation in sealed enclosures or high-ambient industrial/aerospace environments |
| Package Type | TO-46 metal can (NDV0003H) - provides hermetic sealing and EMI shielding for critical analog circuits |
| ESD Rating | 1000 V HBM - requires handling precautions but exceeds standard commercial ICs |
Pinout & Package
LM136AH-5.0/883 uses a 3-lead TO-46 metal-can package (JEDEC TO-46 / TI NDV0003H outline), with leads arranged in bottom-view clockwise order: Pin 1 = Anode, Pin 2 = Cathode, Pin 3 = Adjust. Hermetic sealing and low thermal resistance (θJC = 46°C/W) support high-stability mounting on thermally controlled PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Anode) | Reference ground return path | Connected to system ground; carries reverse current during regulation; must be low-impedance |
| Pin 2 (Cathode) | Output reference node | Provides stable 5.0V output; connects to load or op-amp input; sensitive to layout parasitics |
| Pin 3 (Adjust) | Trim control terminal | Enables fine adjustment of breakdown voltage and temperature coefficient via external resistor network |
Key Features
| Feature | Design Value |
|---|---|
| Adjustable reference range | 4V to 6V via external potentiometer - accommodates initial tolerance and buffer circuit errors without redesign |
| Temperature coefficient tuning | Minimized drift when adjusted to 5.00V with series diodes - enables <±10 ppm/°C performance in calibrated systems |
| Wide operating current | 0.6 mA to 10 mA - eliminates need for current-limiting resistors in low-power sensor interfaces |
| Low dynamic impedance | 1.6Ω - reduces output ripple by >20 dB compared to discrete zener diodes at same current |
| MIL-STD-883 qualified | Group A testing across all 14 subgroups - confirms reliability for space, avionics, and defense electronics |

Equivalent & Alternatives
The following parts are listed as comparable options for similar shunt voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM136H-5.0/883 | Standard LM136 grade (4.87V–5.08V initial tolerance), same TO-46 package and MIL-STD-883 screening | Lower initial accuracy; suitable where post-calibration trim compensates wider initial spread | Select when cost sensitivity outweighs need for tighter initial 5.0V match |
| REF5050QML | 5.0V series reference (not shunt), 3ppm/°C tempco, SOIC-8 package, no adjust pin | Requires higher supply headroom; not usable as negative reference or crowbar circuit element | Select when ultra-low drift and low-output-capacitance drive are prioritized over shunt flexibility |
Compared with LM136H-5.0/883 and REF5050QML, the LM136AH-5.0/883 delivers superior initial accuracy and full shunt configurability - essential for crowbar protection, bipolar references, and low-headroom systems where the adjust pin enables in-situ calibration without component replacement.

FAQ
What is the initial voltage tolerance of LM136AH-5.0/883 at 1 mA?
The LM136AH-5.0/883 has a guaranteed reverse breakdown voltage of 4.93V to 5.02V when tested at 1 mA, per its LM136A-grade specification and MIL-STD-883 Group A testing. This tighter tolerance distinguishes it from the standard LM136-5.0/883 (4.87V–5.08V), making LM136AH-5.0/883 preferred for systems requiring minimal post-trim calibration effort. The value is measured under controlled lab conditions and applies across the full −55°C to +125°C operating range.
Can LM136AH-5.0/883 be used as a negative voltage reference?
Yes, LM136AH-5.0/883 can function as a negative voltage reference because it operates as a shunt regulator - its anode and cathode terminals are bidirectional in application. When the anode is held at a fixed positive potential and the cathode is connected to signal ground, the device regulates −5.0V relative to that ground. This capability is explicitly confirmed in the TI datasheet and used in Figure 18 (Bipolar Output Reference). No polarity reversal damage occurs within absolute maximum ratings.
What is the purpose of the Adjust pin (Pin 3) on LM136AH-5.0/883?
The Adjust pin (Pin 3) on LM136AH-5.0/883 enables external trimming of both reverse breakdown voltage and temperature coefficient. By connecting a potentiometer between cathode and adjust, users can fine-tune output to exactly 5.00V; adding series silicon diodes (e.g., 1N4148) between adjust and ground minimizes temperature drift. This pin is not a feedback input - it modifies internal bandgap biasing, and its current remains within ±260 µA across all valid trim configurations.
Is LM136AH-5.0/883 compatible with lead-free reflow processes?
No - LM136AH-5.0/883 is marked "No" for RoHS compliance in TI's packaging addendum and specified for 300°C peak solder temperature (10 seconds), consistent with SnPb eutectic reflow. Its TO-46 metal-can package uses non-RoHS-compliant lead finish, and TI documentation states "Call TI" for finish details. For lead-free assembly, TI recommends evaluating LM136AH-5.0-SMD variants or alternative references like REF5050QML, which support Pb-free reflow profiles.
How does LM136AH-5.0/883 differ from commercial-grade LM136A-5.0?
LM136AH-5.0/883 differs from commercial LM136A-5.0 in three key ways: (1) it is screened per MIL-STD-883 Group A with full temperature-subgroup testing (−55°C/+25°C/+125°C), (2) it uses a hermetically sealed TO-46 metal-can package (NDV0003H) instead of plastic, and (3) it carries the /883 suffix denoting QML certification for high-reliability programs. Electrical specs are identical, but LM136AH-5.0/883 guarantees performance under military environmental stress and long-term storage conditions.
