Product details
Overview
LM136H-5.0 from Texas Instruments is a precision 5.0V shunt voltage reference diode in a TO-metal-can package, rated for −55°C to +125°C operation, with ±1% initial tolerance, 0.6Ω dynamic impedance, and wide operating current range of 600 μA to 10 mA. It serves as a stable low-voltage reference in digital voltmeters, precision power supplies, and op amp biasing circuits.
For engineers reviewing the LM136H-5.0 datasheet, LM136H-5.0 pinout, LM136H-5.0 application, or LM136H-5.0 equivalent, key selection considerations include its trimmable temperature coefficient, low dynamic impedance, extended industrial temperature range, and compatibility with both positive and negative reference configurations.
Technical Context
The LM136H-5.0 functions as a monolithic shunt regulator with zener-like behavior but achieves superior stability via internal bandgap-derived reference architecture. Its third terminal enables external adjustment of both output voltage (±1 V typical) and temperature coefficient without coupling between parameters.
It operates across 600 μA–10 mA reverse current, maintaining 5.00 V nominal output with ≤20 mV total temperature drift over −55°C to +125°C and ≤12 mV change with current variation - enabling use in low-power, high-stability analog monitoring and calibration systems where supply headroom is constrained.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reference Voltage | 5.00 V nominal at 1 mA; tight 4.9–5.1 V min/max ensures accurate ADC/DAC reference or feedback setpoint. |
| Initial Tolerance | ±1% at 25°C; reduces system calibration burden in production test and field-trimmed instrumentation. |
| Dynamic Impedance | 0.6 Ω typical; minimizes output voltage shift under load transients, critical for stable feedback loops. |
| Operating Current Range | 600 μA to 10 mA; supports ultra-low-power sensor interfaces and high-current reference buffering without external gain stages. |
| Temperature Range | −55°C to +125°C; qualified for aerospace, downhole, and automotive under-hood applications requiring extended thermal robustness. |
| Tempco Stability | ≤20 mV over full range; enables <0.02%/°C effective tempco when trimmed, suitable for precision thermocouple cold-junction compensation. |
| Adjustment Range | ±1 V typical via external potentiometer; allows correction of initial tolerance and buffer amplifier offset errors in final assembly. |
Pinout & Package
LM136H-5.0 uses a hermetically sealed TO-metal-can (NDV) 3-pin package with 2.67 mm max height, designed for high-reliability environments and compatible with standard TO-46 footprint layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Pin 1) | Current sink terminal | Connects to ground or negative rail; defines reference polarity and enables bidirectional (positive/negative) reference configuration. |
| Cathode (Pin 2) | Output voltage node | Provides regulated 5.0V output; must be decoupled with ≥0.1 μF capacitor to suppress high-frequency noise and improve transient response. |
| Adjust (Pin 3) | Trim control terminal | Allows independent tuning of reference voltage and temperature coefficient using external resistor network; no connection required for fixed 5.0V operation. |
Key Features
| Feature | Design Value |
|---|---|
| Low dynamic impedance | 0.6 Ω enables <1 mV output shift under 1 mA load step, preserving accuracy in closed-loop regulation. |
| Wide operating current | 600 μA–10 mA range supports direct interface with microcontroller GPIOs or low-quiescent LDOs without series resistors. |
| Three-terminal adjustability | Independent trimming of voltage and tempco avoids trade-offs seen in two-terminal references, simplifying high-accuracy calibration. |
| Extended temperature rating | −55°C to +125°C operation eliminates derating concerns in military, avionics, and industrial control enclosures. |
| Fast turn-on response | Sub-10 μs stabilization time allows use in power-good detection and fast-switching reference enable schemes. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar shunt voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM336BZ-5.0/NOPB | TO-92 plastic package; 0°C to +70°C rating; ±1% tolerance; 0.8Ω dynamic impedance. | Commercial-grade only; unsuitable for extended temperature or hermetic requirements. | Select when cost-sensitive, non-military applications allow reduced temp range and plastic packaging. |
| TL431ACDR | Adjustable 2.5V reference; SOIC-8; ±1% tolerance; 0.22Ω dynamic impedance; requires external resistors for 5V setup. | Higher precision and lower impedance but lacks integrated 5V option and trim terminal for tempco optimization. | Select when board space permits SOIC layout and adjustable output with tighter impedance is prioritized over single-pin trim capability. |
Compared with LM336BZ-5.0/NOPB, LM136H-5.0 delivers superior thermal robustness and hermetic reliability; compared with TL431ACDR, it offers direct 5V output and dedicated tempco trimming-reducing component count and improving long-term stability in harsh environments.

FAQ
What is the maximum reverse current rating for LM136H-5.0?
The absolute maximum reverse current for LM136H-5.0 is 15 mA, per TI's SNVS750D datasheet. Continuous operation above 10 mA is not recommended, as electrical characteristics are specified only up to 10 mA. Exceeding this may increase self-heating and degrade long-term stability; proper heat sinking or current limiting is advised in high-current applications involving LM136H-5.0.
Can LM136H-5.0 be used as a negative voltage reference?
Yes, LM136H-5.0 can function as a negative voltage reference by reversing its polarity: connect the cathode to system ground and the anode to a negative rail, with the adjust pin configured accordingly. This leverages its shunt topology and symmetric breakdown behavior, enabling bipolar reference generation in split-supply op amp circuits - a documented capability confirmed in the LM136H-5.0 application hints section.
Does LM136H-5.0 require an external capacitor for stability?
LM136H-5.0 does not require an external capacitor for basic DC stability, but a 0.1 μF ceramic capacitor placed directly between cathode and anode significantly improves high-frequency noise rejection and transient response. TI's typical application schematics (e.g., Figure 4 and Figure 5) explicitly show this decoupling capacitor, and omitting it may result in >100 μV p-p noise or oscillation under dynamic load conditions affecting LM136H-5.0 performance.
How is the temperature coefficient trimmed on LM136H-5.0?
The temperature coefficient of LM136H-5.0 is trimmed using the adjust pin (Pin 3) in conjunction with a series diode network - typically four silicon signal diodes (e.g., 1N4148) - as shown in Figure 15 of the SNVS750D datasheet. When adjusted to exactly 5.00 V, the net tempco is minimized; the diodes must be thermally coupled to the LM136H-5.0 die for effective compensation, and the network resistance (2k–20kΩ) is non-critical but should include fixed resistors to stabilize potentiometer settings.
Is LM136H-5.0 RoHS compliant?
Yes, the LM136H-5.0/NOPB variant is RoHS compliant (lead-free), as confirmed in TI's PACKAGE OPTION ADDENDUM. The base LM136H-5.0 part carries leaded finish, but the /NOPB suffix denotes compliance with EU RoHS Directive 2011/65/EU. Both variants share identical electrical and thermal specifications; only the termination material differs - a critical distinction for LM136H-5.0 procurement in environmentally regulated markets.
