Product details
Overview
LM336-5 MWC from Texas Instruments is a precision 5.0V shunt voltage reference diode in a TO-92 package, featuring ±1% initial tolerance, 0.6Ω dynamic impedance, and operation over 0°C to +70°C. It functions as a low-temperature-coefficient zener replacement in analog front-ends, power supply feedback loops, and calibration circuits requiring stable 5V references.
For engineers reviewing the LM336-5 MWC datasheet, LM336-5 MWC pinout, LM336-5 MWC application, or LM336-5 MWC equivalent, key selection criteria include temperature stability (±12 mV over 0°C–70°C), wide operating current range (600 μA to 10 mA), trimmable breakdown voltage (±1 V), and compatibility with low-voltage supplies.
Technical Context
The LM336-5 MWC operates as a two-terminal shunt regulator with a third terminal enabling external adjustment of both output voltage and temperature coefficient. Its monolithic IC construction delivers zener-like behavior with significantly lower dynamic impedance than discrete zeners.
It supports bidirectional reference use (positive or negative rail) and integrates trimming capability via an external potentiometer or diode network-enabling optimization for minimum temperature drift or adjustable 4V–6V output without altering thermal performance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reference Voltage | 5.00 V nominal at 1 mA; ±1% initial tolerance ensures accurate system-level calibration without post-manufacture trimming. |
| Temperature Stability | ±12 mV over 0°C to +70°C; enables stable reference performance in commercial-grade instrumentation and data acquisition systems. |
| Dynamic Impedance | 0.6 Ω typical at 1 mA; minimizes output voltage variation under load transients, critical for high-precision ADC/DAC biasing. |
| Operating Current Range | 600 μA to 10 mA; allows flexible biasing in low-power sensor interfaces and battery-operated devices. |
| Adjustment Range | ±1 V around 5.0 V; supports fine-tuning to compensate for PCB trace resistance, op-amp offset, or supply tolerance. |
| Thermal Resistance θJA | 180°C/W (TO-92, 0.4″ leads); defines maximum power dissipation limit (≈278 mW at 70°C ambient) for reliable long-term operation. |
Pinout & Package
LM336-5 MWC is housed in a 3-pin TO-92 plastic package (JEDEC TO-226AA), with leads formed for through-hole mounting. The package provides mechanical robustness and thermal performance suitable for commercial-grade applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Pin 1) | Current sink terminal | Connected to ground or negative rail when used as positive reference; enables bidirectional configuration. |
| Cathode (Pin 2) | Reference output node | Delivers regulated 5.0V relative to Anode; requires series resistor for current biasing in shunt mode. |
| Adjust (Pin 3) | Trim control terminal | Accepts external potentiometer or diode network to adjust voltage or minimize temperature coefficient without affecting regulation stability. |
Key Features
| Feature | Design Value |
|---|---|
| Low dynamic impedance | 0.6 Ω ensures minimal output voltage shift under varying load currents-critical for high-resolution measurement systems. |
| Wide operating current | 600 μA–10 mA range simplifies bias design across low-power and moderate-current applications without external amplification. |
| Adjustable reference voltage | ±1 V trim range accommodates system-level tolerances and enables use as 4–6 V reference in non-standard supply architectures. |
| Three-terminal architecture | Separate Adjust pin allows independent optimization of voltage accuracy and temperature drift-unavailable in standard zener diodes. |
| Commercial temperature grade | 0°C to +70°C rating targets cost-sensitive industrial controls, consumer electronics, and embedded sensors where extended temperature range is unnecessary. |

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 | Same TO-92 package, identical electrical specs, RoHS-compliant lead finish (Sn), rated for 0°C to +70°C. | No functional difference; differs only in packaging compliance and marking format (LM336BZ5.0 vs MWC). | Select LM336BZ-5.0/NOPB for RoHS-compliant production requiring standard reel/bulk delivery and TI's current commercial marking. |
| TL431ACDBVR | 3-pin adjustable shunt regulator; 2.495V nominal, adjustable up to 36V; higher initial accuracy (±0.5%), but requires external resistors for 5V setup. | Not drop-in: needs resistor network for 5V; superior accuracy and wider voltage range suit programmable supplies, but lacks LM336-5 MWC's integrated 5V optimization. | Choose TL431ACDBVR when system requires tighter initial tolerance or multi-voltage flexibility; LM336-5 MWC remains optimal for fixed 5V, low-component-count designs. |
Compared with LM336BZ-5.0/NOPB, LM336-5 MWC shares identical performance but reflects an earlier orderable variant with distinct part marking and carrier format; versus TL431ACDBVR, LM336-5 MWC offers simpler 5V implementation with no external resistors, though at lower absolute accuracy.

FAQ
What is the operating temperature range for LM336-5 MWC?
The LM336-5 MWC is specified for operation from 0°C to +70°C, aligning with commercial-grade applications such as consumer electronics, industrial controls, and test equipment where extended temperature performance is not required. This range is confirmed in TI's SNVS750D datasheet and PACKAGE OPTION ADDENDUM.
Does LM336-5 MWC require external components to function as a 5.0V reference?
Yes, LM336-5 MWC requires an external current-setting resistor between the cathode and supply rail to establish its operating current within 600 μA–10 mA. No other passive components are needed for basic 5.0V operation, though a potentiometer may be added to Pin 3 for trimming.
Can LM336-5 MWC be used as a negative voltage reference?
Yes, LM336-5 MWC supports bidirectional configuration: connecting the Anode (Pin 1) to a positive rail and Cathode (Pin 2) to ground yields a −5.0V reference relative to ground, leveraging its shunt regulator topology-confirmed in the device description and Figure 21 (Bipolar Output Reference) of the datasheet.
What is the maximum power dissipation for LM336-5 MWC in TO-92 package?
With θJA = 180°C/W and max junction temperature TJ = 100°C (per Thermal Characteristics table), LM336-5 MWC dissipates up to 278 mW at 70°C ambient (P = ΔT/θJA). This limits continuous current to ≈55.6 mA at 5V, but typical operation stays within 1–10 mA per Electrical Characteristics.
Is LM336-5 MWC pin-compatible with LM336BZ-5.0/NOPB?
Yes, LM336-5 MWC and LM336BZ-5.0/NOPB share identical TO-92 package outline, pin assignment (Anode–Cathode–Adjust), and mechanical dimensions per TI's LP0003A drawing-making them physically and electrically interchangeable in existing layouts, differing only in RoHS compliance and marking.
