Product details
Overview
NZX6V8D,133 from Nexperia is a single Zener diode in a hermetically sealed SOD27 (SC-40) glass package, designed for precision voltage regulation at 6.8 V nominal working voltage with ±0.3 V tolerance, 15 Ω differential resistance at IZ = 5 mA, and ≤2 µA reverse leakage current. It delivers stable reference voltage in low-power analog circuits, power supply feedback loops, and overvoltage protection stages.
For engineers reviewing the NZX6V8D,133 datasheet, NZX6V8D,133 pinout, NZX6V8D,133 application, or NZX6V8D,133 equivalent, this device is selected for its low thermal resistance (380 K/W junction-to-ambient), axial-leaded glass construction enabling high reliability in temperature-critical environments, and tight VZ distribution across production lots.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain a stable reference voltage under varying load and temperature conditions. Its 6.8 V nominal Zener voltage is specified at IZ = 5 mA, with a temperature coefficient of approximately +2 mV/K near this current, supporting predictable drift behavior in compensated designs.
The SOD27 package provides hermetic sealing against moisture and contaminants, while its axial lead configuration supports through-hole mounting on FR4 PCBs without thermal pads. Thermal resistance values (Rth(j-a) = 380 K/W, Rth(j-t) = 300 K/W) reflect performance under standard test conditions with 8 mm lead length.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 6.6 V to 6.9 V at IZ = 5 mA - defines precise regulation window for feedback or clamping |
| Differential Resistance (rdif) | 15 Ω max at IZ = 5 mA - ensures minimal output voltage variation under load changes |
| Reverse Leakage Current (IR) | ≤2 µA at VR = 4 V - guarantees low standby power loss in battery-sensitive applications |
| Total Power Dissipation (Ptot) | 500 mW max at Ttp ≤ 25 °C - sets safe DC operating limit for continuous regulation |
| Junction Temperature (Tj) | −65 °C to +175 °C - enables operation in extended industrial and automotive-adjacent environments |
| Forward Voltage (VF) | ≤1.5 V at IF = 200 mA - supports use as low-drop rectifier or polarity indicator when forward-biased |
Pinout & Package
The NZX6V8D,133 uses a two-terminal axial-leaded SOD27 (SC-40) hermetically sealed glass package. The cathode is marked by a band on the glass body.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (banded end) | Cathode | Connected to regulated output node in shunt regulator configurations; accepts reverse bias for Zener conduction |
| 2 (unbanded end) | Anode | Connected to ground or lower-potential rail; completes current path during regulation |
Key Features
| Feature | Design Value |
|---|---|
| Hermetic glass encapsulation | Prevents moisture ingress and long-term parameter drift in humid or harsh environments |
| Low differential resistance (15 Ω) | Minimizes regulation error across ±1 mA load current variations in feedback networks |
| Controlled temperature coefficient | +2 mV/K near 5 mA enables predictable VZ shift for thermal compensation design |
| High-reliability axial lead form | Supports manual or wave soldering with mechanical stability and proven field longevity |
Applications
| Power Supply Feedback Regulation | Overvoltage Clamp Protection |
|---|---|
|
Use Scenario: Stabilizing output voltage in linear regulators or switching converter feedback paths. IC Role / Device Role / Timing Role: Shunt reference element providing precise 6.8 V threshold to error amplifier input. Use Value: Tight VZ tolerance (±0.3 V) and low rdif ensure <±1% output regulation accuracy under line/load transients. |
Use Scenario: Limiting transient voltage spikes on microcontroller I/O lines or sensor inputs. IC Role / Device Role / Timing Role: Passive clamp that conducts above 6.8 V to divert surge energy to ground. Use Value: Low leakage (<2 µA) prevents signal loading; fast response (<100 ns) suppresses ESD events per IEC 61000-4-2 Level 4. |
| Reference Voltage Source | Threshold Detection Circuit |
|
Use Scenario: Generating stable bias points for op-amp comparators or ADC reference dividers. IC Role / Device Role / Timing Role: Precision voltage node referenced to system ground for analog signal conditioning.

Use Scenario: Detecting battery voltage drop below safe operating level in portable devices. IC Role / Device Role / Timing Role: Zener-based comparator input threshold set to 6.8 V for Li-ion cell undervoltage lockout. Use Value: Predictable temperature coefficient (+2 mV/K) allows accurate cold-temperature threshold adjustment without external compensation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX55C6V8 | Plastic DO-35 package; higher rdif (20 Ω); wider VZ tolerance (±5%) | Limited to non-critical commercial applications due to lower stability and moisture sensitivity | Select when cost is primary and environmental stress is minimal |
| 1N4735A | DO-41 package; Ptot = 1 W; rdif = 3.5 Ω; VZ = 6.2 V (not 6.8 V) | Higher power handling but mismatched voltage grade requires circuit redesign | Select only if 6.2 V is acceptable and >500 mW dissipation is required |
Compared with BZX55C6V8 and 1N4735A, NZX6V8D,133 offers superior long-term stability via hermetic sealing, tighter voltage tolerance, and optimized thermal resistance for compact PCB layouts-making it preferred for industrial-grade regulation where parameter consistency matters.

FAQ
What is the maximum continuous Zener current for NZX6V8D,133?
The absolute maximum forward current is 250 mA, but continuous Zener operation is limited by power dissipation. At 6.8 V, the maximum DC Zener current is 73.5 mA (500 mW ÷ 6.8 V), assuming ambient temperature ≤25 °C and no heatsinking. Derating applies above 25 °C per the thermal resistance specification.
Can NZX6V8D,133 be used in surface-mount designs?
No - NZX6V8D,133 uses an axial-leaded SOD27 (SC-40) glass package intended for through-hole mounting. It lacks surface-mount terminations or reflow-compatible construction. For SMT equivalents, consider Nexperia's BZX384-B6V8 or MMBZ5236B, which offer similar electrical specs in SOT-23 packages.
How does the temperature coefficient affect regulation accuracy?
At IZ = 5 mA, NZX6V8D,133 exhibits a positive temperature coefficient of approximately +2 mV/K. Over a −40 °C to +125 °C range, this results in ~330 mV total VZ shift - a key factor in precision references. Designers compensate using complementary components or operate near 25 °C for minimal drift.
Is NZX6V8D,133 suitable for automotive applications?
No - this part is not AEC-Q200 qualified. The datasheet explicitly states it is "non-automotive qualified" and unsuitable for safety-critical or life-critical systems. Automotive designs require parts tested to AEC-Q200 with documented PPAP, qualification reports, and guaranteed lot traceability - none of which apply to NZX6V8D,133.
