Product details
Overview
PZU6.2B3A,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 and 30 nA reverse current at 0.5 mA, used for precision voltage reference and overvoltage protection in low-power analog circuits.
For engineers reviewing the PZU6.2B3A,115 datasheet, PZU6.2B3A,115 pinout, PZU6.2B3A,115 application, or PZU6.2B3A,115 equivalent, key selection criteria include Zener voltage tolerance (±2 %), low dynamic impedance at regulation current, thermal resistance to solder point (255 K/W), and SOD323 footprint compatibility with high-density PCB layouts.
Technical Context
This Zener diode operates in reverse breakdown mode with hard knee characteristics optimized for stable reference generation. Its 6.2 V nominal Zener voltage falls in the region where temperature coefficient crosses zero (~6.2 V), minimizing drift across operating temperature ranges.
The device delivers 30 nA reverse leakage at IZ = 0.5 mA and maintains ≤80 Ω differential resistance at IZ = 5 mA, enabling accurate regulation under light-load conditions typical in sensor biasing and ADC reference circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 6.26 V to 6.53 V at IZ = 5 mA - ensures ±2 % regulation accuracy for stable reference design |
| Differential Resistance rdif | ≤80 Ω at IZ = 5 mA - minimizes output voltage variation under load current changes |
| Reverse Current IR | ≤30 nA at VR = 4.0 V - enables ultra-low power standby operation without significant quiescent loss |
| Total Power Dissipation Ptot | 320 mW at Tamb ≤ 25 °C on FR4 PCB - defines maximum continuous DC power handling in standard layout |
| Non-repetitive Peak Power PZSM | 40 W at tp = 100 µs - supports transient surge clamping in ESD/overvoltage protection circuits |
| Junction-to-Solder-Point Rth(j-sp) | 255 K/W - determines thermal rise above PCB copper during pulsed operation |
| Package | SOD323 (SC-76), 1.7 mm × 1.25 mm × 0.95 mm - enables 0.65 mm pad pitch and high-density surface-mount assembly |
Pinout & Package
SOD323 (SC-76) plastic surface-mount package with cathode marked by bar; body dimensions 1.7 mm × 1.25 mm × 0.95 mm, lead pitch 1.3 mm, compatible with reflow and wave soldering per IPC-7351B.
| 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; forms reverse-biased junction for Zener operation |
Key Features
| Feature | Design Value |
|---|---|
| ±2 % Zener voltage tolerance (B3 series) | Enables tighter regulation than ±5 % parts, reducing need for post-calibration in precision references |
| Hard breakdown knee | Ensures sharp, predictable turn-on at nominal VZ, critical for clean voltage limiting in signal conditioning paths |
| Low 30 nA leakage at 0.5 mA | Minimizes error contribution in high-impedance bias networks and battery-powered sensor interfaces |
| Optimized for fast switching & noise reduction | Intentional minor leakage rise improves transient response and reduces broadband noise in feedback loops |
| SOD323 footprint compatibility | Supports automated placement and reflow in high-volume production with IPC-compliant land patterns |

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, ±2 % tolerance, but higher 100 nA IR at 4 V and 100 Ω rdif | Less suitable for ultra-low-leakage bias networks; acceptable for general-purpose clamping | Select when cost sensitivity outweighs leakage or impedance requirements |
| MMSZ4687T1G | SOD-123 package (larger), ±5 % tolerance, 200 nA IR, 100 Ω rdif, 500 mW Ptot | Higher power dissipation but looser tolerance and larger footprint limits high-density designs | Choose only if board layout allows SOD-123 and ±5 % regulation is acceptable |
Compared with BZX384-B6V2,115 and MMSZ4687T1G, PZU6.2B3A,115 offers superior regulation precision (±2 %), lower dynamic impedance (≤80 Ω vs ≥100 Ω), and significantly reduced leakage (30 nA vs ≥100 nA), making it optimal for high-accuracy, space-constrained analog subsystems.

FAQ
What is the maximum continuous reverse current the PZU6.2B3A,115 can sustain at 25 °C ambient?
The device is rated for 200 mA maximum forward current, but as a Zener regulator, its continuous reverse current is limited by power dissipation. At 25 °C ambient on an FR4 PCB, Ptot = 320 mW implies IZ ≤ 51.6 mA at 6.2 V - however, derating is required above 25 °C per the thermal resistance curve.
Does the PZU6.2B3A,115 exhibit zero temperature coefficient at its nominal Zener voltage?
Yes - the 6.2 V nominal point lies at the crossover where the temperature coefficient (SZ) transitions from negative to positive, yielding near-zero drift (±0.3 mV/K typical) across -40 °C to +125 °C, as confirmed in Figures 3–4 of the datasheet.
Can PZU6.2B3A,115 be used in parallel for higher power handling?
No - Zener diodes cannot be reliably paralleled due to mismatched VZ and rdif, causing current hogging. For higher power, use a single higher-rated device or implement active regulation; the 40 W non-repetitive rating applies only to single-pulse events.
Is the SOD323 footprint of PZU6.2B3A,115 compatible with automated optical inspection (AOI)?
Yes - the SOD323 package has standardized dimensions (1.7 mm × 1.25 mm) and visible cathode marking bar, meeting IPC-A-610 Class 2/3 requirements for AOI detection of polarity, placement, and solder joint integrity in high-volume manufacturing.
