Product details
Overview
PZU84-C6V2R from Nexperia is a ±2 % tolerance Zener voltage regulator diode in SOT23 package, providing precise 6.2 V regulation at 5 mA with 80 Ω differential resistance and 0.4 mV/K temperature coefficient, used for low-power reference and overvoltage protection in power supply feedback loops.
For engineers reviewing the PZU84-C6V2R datasheet, PZU84-C6V2R pinout, PZU84-C6V2R application, or PZU84-C6V2R equivalent, this page delivers verified Zener parameters including VZ, rdif, IR, thermal resistance, and SOT23 terminal mapping - critical for precision biasing, voltage clamping, and analog reference design.
Technical Context
This Zener operates in reverse breakdown mode with hard knee characteristics, optimized for stable DC regulation at low currents (IZ = 0.5–5 mA). Its 80 Ω dynamic impedance at 5 mA and 0.5 μA max reverse leakage at VR = 5 V ensure minimal regulation error under light load.
Designed for surface-mount use on FR4 PCBs, it features Rth(j-a) = 500 K/W and Rth(j-sp) = 330 K/W, enabling reliable thermal performance up to 150 °C junction temperature while dissipating ≤250 mW continuously.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 6.2 V nominal, 5.86–6.53 V range at IZ = 5 mA - ensures tight regulation for 6 V rail monitoring |
| Differential Resistance rdif | 80 Ω max at IZ = 5 mA - minimizes output voltage shift under load variation |
| Reverse Leakage IR | 0.5 μA max at VR = 5 V - preserves low quiescent current in battery-powered references |
| Temperature Coefficient SZ | +0.4 mV/K typical - enables predictable drift compensation in temperature-sensitive circuits |
| Total Power Dissipation Ptot | 250 mW at Tamb = 25 °C on standard FR4 - defines maximum continuous bias current (≈40 mA at 6.2 V) |
| Forward Voltage VF | 0.9 V max at IF = 10 mA - supports bidirectional clamping when used with series resistor |
| Junction Temperature Tj | −55 °C to +150 °C - allows operation in industrial and extended-temperature environments |
Pinout & Package
SOT23 plastic surface-mount package: 2.9 mm × 1.3 mm × 1.0 mm body, 1.9 mm pin pitch, tin-plated terminations.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode (A) | Connects to lower-potential node in reverse-bias configuration; forward conduction path when polarity reversed |
| 2 | Not Connected (n.c.) | Internally unconnected; must remain floating - no PCB trace or solder mask opening required |
| 3 | Cathode (K) | Connects to higher-potential node in Zener mode; primary heat-sinking terminal (Rth(j-sp) = 330 K/W) |
Key Features
| Feature | Design Value |
|---|---|
| ±2 % VZ tolerance | Enables high-accuracy voltage references without post-calibration in 6.2 V systems |
| Hard breakdown knee | Ensures sharp, repeatable turn-on for clean clamping and stable regulation below 1 mA |
| Low 0.5 μA leakage at 5 V | Reduces standby power loss in always-on monitoring circuits and IoT sensor nodes |
| 80 Ω dynamic impedance | Maintains regulation stability across ±10 % load current changes in feedback networks |
| SOT23 footprint compatibility | Supports automated placement and reflow on standard 0.6 mm pad layouts per Nexperia's recommended footprint |
Applications
| Power Supply Feedback Reference | Overvoltage Clamp Protection |
|---|---|
Use Scenario: Stabilizing output voltage in isolated flyback or buck converter feedback loop using optocoupler-coupled TL431 alternative. IC Role / Device Role / Timing Role: Zener diode provides fixed 6.2 V reference for error amplifier input, replacing higher-cost programmable shunt regulators. Use Value: Delivers ±2 % accuracy and 80 Ω impedance to minimize output voltage drift across line/load/temperature variations. |
Use Scenario: Protecting microcontroller GPIO pins from transient surges on 5 V I/O lines in industrial control panels. IC Role / Device Role / Timing Role: Acts as fast-acting shunt clamp between signal line and ground, diverting ESD or inductive kick energy. Use Value: Low 0.5 μA leakage avoids signal loading; hard knee ensures clamping begins precisely at 6.2 V, limiting overshoot to <7 V. |
| Low-Power Sensor Biasing | ADC Reference Stabilization |
Use Scenario: Providing stable excitation voltage to resistive temperature detectors (RTDs) in battery-powered environmental monitors. IC Role / Device Role / Timing Role: Supplies regulated 6.2 V bias to RTD bridge, eliminating need for LDO in ultra-low-power designs. Use Value: 250 mW power rating supports 40 mA max bias current; 0.4 mV/K tempco enables simple software compensation. |
Use Scenario: Improving accuracy of 12-bit SAR ADCs by stabilizing external reference input against supply ripple. IC Role / Device Role / Timing Role: Regulates reference voltage node upstream of RC filter feeding ADC REF+ pin. Use Value: 80 Ω rdif prevents reference droop during ADC sampling transients; SOT23 size fits dense mixed-signal layouts. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C6V2 | Same 6.2 V ±5 % tolerance, 100 Ω rdif, 1 μA IR - looser tolerance and higher impedance than PZU84-C6V2R | Acceptable where ±5 % regulation accuracy suffices and 100 Ω impedance does not degrade loop stability | Select when cost sensitivity outweighs precision requirements and board space permits same SOT23 footprint |
| MMSZ4687 | 6.2 V ±5 %, 100 Ω rdif, 1 μA IR, 350 mW Ptot - higher power but lower accuracy and leakage performance | Suitable for higher-current clamping (up to 56 mA), not optimal for low-leakage reference use | Choose only if thermal margin demands >250 mW dissipation and ±2 % tolerance is unnecessary |
Compared with BZX84-C6V2 and MMSZ4687, PZU84-C6V2R offers superior regulation precision (±2 % vs. ±5 %), lower dynamic impedance (80 Ω vs. 100 Ω), and half the leakage current (0.5 μA vs. 1 μA), making it preferred for high-accuracy, low-power reference and clamping roles.

FAQ
What is the maximum continuous reverse current for stable Zener operation?
The PZU84-C6V2R is rated for continuous operation up to 40 mA at 6.2 V (250 mW), but optimal regulation occurs between 0.5 mA and 20 mA. At 5 mA, it achieves specified 80 Ω differential resistance and ±2 % VZ tolerance; exceeding 20 mA risks thermal instability without heatsinking.
Can Pin 2 be grounded or left floating in PCB layout?
Pin 2 is internally not connected (n.c.) and must remain electrically floating - no trace, via, or solder mask opening should contact it. Grounding Pin 2 creates an unintended parasitic path and violates the device's internal construction, potentially causing regulation failure or premature wear.
How does the +0.4 mV/K temperature coefficient affect circuit accuracy over −40 °C to +85 °C?
Over that range, the coefficient causes ≈50 mV total VZ drift (0.4 mV/K × 125 K), resulting in ≈±0.8 % change relative to 6.2 V nominal. This is within the ±2 % initial tolerance band, so system-level accuracy remains dominated by initial calibration rather than thermal drift.
Is PZU84-C6V2R suitable for ESD protection per IEC 61000-4-2?
No - while it clamps transients, its 40 W non-repetitive peak power rating applies only to single 100 μs pulses, not the multi-pulse stress of IEC 61000-4-2. Dedicated TVS diodes like PESD5V0S1BA are required for certified ESD protection; PZU84-C6V2R serves only as basic overvoltage limiter.
