Product details
Overview
PZU6.2B2A,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 3.0 mV/K temperature coefficient. It delivers stable reference voltage in low-power analog circuits, power supply feedback loops, and overvoltage protection stages.
For engineers reviewing the PZU6.2B2A,115 datasheet, PZU6.2B2A,115 pinout, PZU6.2B2A,115 application, or PZU6.2B2A,115 equivalent, key selection criteria include tight voltage tolerance, low dynamic impedance at regulation current, thermal stability across operating temperature, and compatibility with high-density SMT layouts using standard FR4 PCB footprints.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain a precise DC reference voltage under varying load and input conditions. Its hard breakdown knee and intentional minor leakage rise optimize switching speed and noise performance per AN90031, distinguishing it from general-purpose Zeners.
Designed for surface-mounted use on single-sided tin-plated FR4 boards, it supports non-repetitive surge handling up to 40 W (100 µs square wave) and continuous dissipation of 320 mW at 25 °C ambient, with junction-to-solder-point thermal resistance of 55 K/W.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Zener Voltage | 6.2 V at IZ = 5 mA - defines primary regulation point for feedback and clamping circuits |
| Voltage Tolerance | ±2 % (B2 series) - ensures tight output voltage consistency across production batches |
| Differential Resistance | ≤80 Ω at IZ = 5 mA - minimizes output voltage variation under load current changes |
| Reverse Current | ≤30 nA at VR = 0.5 mA - enables ultra-low standby power in battery-sensitive designs |
| Temperature Coefficient | +3.0 mV/K - provides predictable, positive drift for compensation in mixed-voltage systems |
| Non-repetitive Peak Power | 40 W (100 µs square wave) - supports transient overvoltage suppression without failure |
| Total Power Dissipation | 320 mW at Tamb ≤ 25 °C on standard FR4 - sets continuous thermal design boundary |
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; marking bar identifies this terminal for correct PCB orientation |
| 2 | Anode | Connected to ground or lower-potential rail; forms reverse-biased junction during regulation |
Key Features
| Feature | Design Value |
|---|---|
| Optimized fast switching | Intentional minor leakage rise reduces switching noise and improves transient response in feedback paths |
| Hard breakdown knee | Sharp, well-defined Zener onset enables accurate voltage clamping without soft rolloff |
| Low dynamic impedance | 80 Ω at 5 mA ensures minimal regulation error under typical bias conditions |
| Surface-mount compatibility | SOD323 footprint aligns with IPC-7351B standard for automated placement and reflow soldering |
Applications
| Power Supply Feedback | Overvoltage Protection |
|---|---|
Use Scenario: Regulating output voltage in isolated flyback or buck converter secondary-side feedback loop. IC Role / Device Role / Timing Role: Provides stable 6.2 V reference to optocoupler input or TL431 control pin. Use Value: ±2 % tolerance and 80 Ω dynamic impedance ensure <±10 mV output deviation across line/load variations. |
Use Scenario: Clamping transient surges on 5 V or 3.3 V logic rails during ESD or inductive switching events. IC Role / Device Role / Timing Role: Acts as shunt limiter, diverting excess current when rail exceeds 6.2 V + forward drop. Use Value: 40 W non-repetitive peak power rating absorbs 100 µs transients without degradation. |
| Reference Voltage Source | Signal Level Shifting |
Use Scenario: Generating precision bias for op-amp comparators or ADC reference inputs in sensor interfaces. IC Role / Device Role / Timing Role: Supplies clean, temperature-compensated 6.2 V reference independent of main supply rails. Use Value: +3.0 mV/K coefficient allows predictable drift tracking for calibration algorithms. |
Use Scenario: Translating 3.3 V logic signals to higher-voltage domains (e.g., 6.2 V) in mixed-signal interface circuits. IC Role / Device Role / Timing Role: Functions as passive level translator via reverse-biased Zener clamp configuration. Use Value: Low 30 nA reverse current at sub-threshold bias minimizes loading on driving source. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX384-B6V2,115 | Same SOD323 package and 6.2 V rating, but ±5 % tolerance (B series), 100 Ω rdif, higher IR (100 nA) | Lower cost for non-critical references; less stable under temperature or load variation | Select when ±5 % tolerance suffices and cost sensitivity outweighs regulation precision |
| MMSZ5234B-TP | SOD-123 package (larger), same 6.2 V/±5 %, 100 Ω rdif, 5 µA IR at 1 V - significantly higher leakage | Compatible with legacy SOD-123 footprints but unsuitable for ultra-low-power or high-density layouts | Choose only if board layout requires SOD-123 or existing BOM mandates Diodes Inc. sourcing |
Compared with PZU6.2B2A,115, BZX384-B6V2,115 trades tighter tolerance and lower impedance for cost, while MMSZ5234B-TP sacrifices SMT density and leakage performance for broader distributor availability - making the PZU6.2B2A,115 optimal for space-constrained, low-noise, precision-regulated designs.

FAQ
What is the maximum continuous power dissipation for PZU6.2B2A,115 at 70 °C ambient?
At 70 °C ambient, derating applies per the thermal resistance curve. With Rth(j-a) = 390 K/W and Tj(max) = 150 °C, the allowable power drops to approximately 205 mW. This is calculated as (150 − 70) / 390 ≈ 0.205 W, confirming safe operation below the 320 mW 25 °C rating.
Can PZU6.2B2A,115 be used in place of a 6.2 V Zener with ±5 % tolerance?
Yes, but only where tighter regulation is beneficial. Its ±2 % tolerance and 80 Ω dynamic impedance improve accuracy and load regulation versus ±5 % parts like BZX384-B6V2,115. No circuit modification is needed, though layout must respect SOD323 footprint and thermal pad requirements.
Does PZU6.2B2A,115 require a heatsink for 320 mW operation?
No external heatsink is required. At 320 mW on a standard FR4 PCB with single-sided copper and tin plating, junction temperature remains within 150 °C limit. Thermal resistance to solder point is only 55 K/W, enabling sufficient heat transfer through the cathode pad alone.
How does the +3.0 mV/K temperature coefficient affect long-term voltage stability?
The +3.0 mV/K coefficient causes a predictable +15 mV shift over a 50 °C ambient range (e.g., 25 °C to 75 °C). This linear drift can be compensated in system-level calibration or paired with negative-coefficient components in bandgap-like reference designs.
