Product details
Overview
PZU6.2B1A,115 from Nexperia is a ±2 % tolerance Zener voltage regulator diode in SOD323 (SC-76) package, rated for 6.2 V nominal working voltage at 5 mA, with 80 Ω maximum differential resistance, 30 nA reverse current at 0.5 mA, and 3 mV/K temperature coefficient. It delivers stable voltage reference in low-power analog circuits, power supply feedback loops, and overvoltage protection stages.
For engineers reviewing the PZU6.2B1A,115 datasheet, PZU6.2B1A,115 pinout, PZU6.2B1A,115 application, or PZU6.2B1A,115 equivalent, this device is selected for precision regulation where tight voltage tolerance, low dynamic impedance, and thermal stability across -55 °C to +150 °C ambient are required.
Technical Context
This Zener diode operates in reverse breakdown mode with hard knee characteristics optimized for low-current regulation (IZ = 5 mA). Its ±2 % tolerance (B1 series) and 3 mV/K temperature coefficient enable predictable drift behavior in bias networks and reference generators.
Designed for surface-mount use on FR4 PCBs, it supports non-repetitive surge handling up to 40 W (100 µs square wave) and continuous dissipation of 320 mW at Tamb ≤ 25 °C with standard footprint mounting.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Zener Voltage (VZ) | 6.2 V at IZ = 5 mA - defines precise regulation point for feedback and reference circuits |
| Tolerance | ±2 % (B1 series) - ensures voltage accuracy within ±0.124 V for high-stability designs |
| Differential Resistance (rdif) | ≤80 Ω at IZ = 5 mA - maintains low output impedance under varying load conditions |
| Reverse Current (IR) | ≤30 nA at VR = 0.5 × VZ - minimizes standby leakage in battery-powered systems |
| Temperature Coefficient (SZ) | +3 mV/K - enables predictable voltage drift compensation in wide-temperature applications |
| Non-repetitive Peak Power (PZSM) | 40 W (100 µs pulse) - supports transient overvoltage clamping without failure |
| Total Power Dissipation (Ptot) | 320 mW at Tamb ≤ 25 °C - sets continuous thermal limit on standard FR4 PCB |
Pinout & Package
SOD323 (SC-76) plastic surface-mount package: 1.7 mm × 1.25 mm × 0.95 mm body, 1.3 mm lead pitch, cathode marked by bar on top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode | Connected to regulated output node; polarity marker (bar) identifies this terminal |
| 2 | Anode | Connected to ground or lower-potential rail; completes reverse-bias path for Zener operation |
Key Features
| Feature | Design Value |
|---|---|
| ±2 % voltage tolerance (B1) | Enables tighter closed-loop regulation than ±5 % variants, reducing need for post-calibration trimming |
| Low differential resistance (≤80 Ω) | Minimizes output voltage variation under load changes, critical for precision analog references |
| Hard breakdown knee | Ensures sharp, repeatable turn-on behavior at 6.2 V, improving noise immunity in sensing paths |
| Low leakage (≤30 nA @ 0.5×VZ) | Reduces quiescent current draw in always-on monitoring circuits and energy-harvesting nodes |
| SOD323 footprint compatibility | Supports high-density PCB layouts and automated reflow assembly with industry-standard land pattern |
Applications
| Power Supply Feedback | Overvoltage Protection |
|---|---|
|
Use Scenario: Regulating output voltage in isolated flyback or buck-derived DC-DC converters via optocoupler-coupled feedback loop. IC Role / Device Role / Timing Role: Zener diode provides stable 6.2 V reference to TL431 or optocoupler LED anode, setting precise output threshold. Use Value: ±2 % tolerance ensures output accuracy within ±0.1 V at 5 V output, meeting industrial power spec requirements. |
Use Scenario: Clamping transient surges on 5 V logic rails during hot-plug or ESD events. IC Role / Device Role / Timing Role: Acts as shunt limiter, conducting when rail exceeds 6.2 V + forward drop of series resistor. Use Value: 40 W non-repetitive surge rating absorbs 100 µs transients without degradation, extending system reliability. |
| Reference Voltage Generator | Current Source Biasing |
|
Use Scenario: Generating stable bias voltage for op-amp input stages or ADC reference buffers in sensor signal chains. IC Role / Device Role / Timing Role: Provides low-noise, thermally stable 6.2 V node for precision analog circuitry operating from 12 V supply. Use Value: +3 mV/K coefficient allows predictable drift modeling; 80 Ω rdif prevents loading-induced error in high-impedance nodes. |
Use Scenario: Setting constant current through LEDs or phototransistors in industrial status indicators or isolation interfaces. IC Role / Device Role / Timing Role: Forms upper leg of two-diode current mirror with matched transistor, defining IOUT ≈ (VZ − VBE)/R. Use Value: Low 30 nA leakage avoids current error accumulation at microamp-level bias currents, ensuring <1 % setpoint deviation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX384-B6V2 | Same 6.2 V / ±2 % / SOD323, but higher rdif (100 Ω max) and higher IR (100 nA) | Less suitable for ultra-low-leakage or high-precision reference use | Select when cost sensitivity outweighs leakage or impedance requirements |
| MMSZ5234B | 6.2 V / ±5 % / SOD123, larger package, higher Ptot (500 mW), rdif = 10 Ω | Better thermal margin but lower voltage accuracy and incompatible footprint | Select for higher-power clamping where board space allows SOD123 and ±5 % tolerance is acceptable |
Compared with BZX384-B6V2, PZU6.2B1A,115 offers tighter leakage control and lower impedance for precision analog use; versus MMSZ5234B, it trades thermal headroom and absolute power rating for superior accuracy and miniaturization in space-constrained designs.

FAQ
What is the maximum continuous power dissipation for PZU6.2B1A,115 on a standard FR4 PCB?
The total power dissipation is 320 mW at ambient temperature ≤ 25 °C when mounted on an FR4 PCB with single-sided copper, tin-plated, and standard SOD323 footprint. Derating applies above 25 °C per the thermal resistance of 255 K/W junction-to-solder-point.
How does the ±2 % tolerance affect regulation accuracy in a 5 V feedback circuit?
At 6.2 V nominal, ±2 % tolerance means the actual Zener voltage falls between 6.076 V and 6.324 V. In a typical TL431-based feedback divider, this translates to ±0.1 V output error at 5 V - sufficient for most industrial power supplies but not for metrology-grade systems requiring tighter calibration.
Can PZU6.2B1A,115 be used in place of a 6.8 V Zener for overvoltage clamping?
No - its 6.2 V nominal Zener voltage is fixed and not interchangeable with 6.8 V devices. Substituting would lower the clamping threshold by 0.6 V, potentially causing premature triggering and disrupting downstream circuit operation. Always match nominal VZ to design-set trip points.
What is the significance of the '115' suffix in PZU6.2B1A,115?
The '115' is Nexperia's internal ordering code denoting tape-and-reel packaging in 10,000-unit reels with standard moisture sensitivity level (MSL) 1 handling, compliant with J-STD-020. It does not indicate electrical or thermal differentiation from other PZU6.2B1A variants.
