Product details
Overview
PZU8.2B2A,115 from Nexperia is a ±2 % tolerance Zener voltage regulator diode in SOD323 (SC-76) package, rated for 8.2 V nominal working voltage, 320 mW total power dissipation at 25 °C ambient, and 150 °C maximum junction temperature. It delivers stable voltage reference in low-power analog circuits, power supply feedback paths, and overvoltage protection clamping networks.
For engineers reviewing the PZU8.2B2A,115 datasheet, PZU8.2B2A,115 pinout, PZU8.2B2A,115 application, or PZU8.2B2A,115 equivalent, this device is selected for precision regulation where tight voltage tolerance, low dynamic impedance at 5 mA, and controlled leakage current are required in space-constrained surface-mount designs.
Technical Context
This Zener diode operates in reverse breakdown with a nominal 8.2 V regulation voltage at IZ = 5 mA, exhibiting a typical differential resistance of 60 Ω and reverse current ≤10 nA at IZ = 0.5 mA. Its temperature coefficient is +4.6 mV/K at 5 mA, indicating positive drift with temperature rise.
The device uses silicon planar technology in a hermetically sealed plastic SOD323 package with cathode marked by a bar. It supports non-repetitive peak reverse current up to 3.5 A (100 µs square wave), enabling transient suppression in low-energy surge scenarios.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Zener Voltage | 8.2 V at IZ = 5 mA - defines precise regulation point for feedback or reference circuits |
| Voltage Tolerance | ±2 % (B2 series) - ensures consistent output across production batches without post-assembly trimming |
| Differential Resistance | 60 Ω max at IZ = 5 mA - limits output voltage variation under load current changes |
| Reverse Current | ≤10 nA at IZ = 0.5 mA - minimizes standby power loss in battery-powered systems |
| Total Power Dissipation | 320 mW at Tamb ≤ 25 °C on FR4 PCB - sets maximum continuous DC power handling in standard layout |
| Junction Temperature | −55 °C to +150 °C - enables operation in industrial and automotive under-hood environments |
| Package | SOD323 (SC-76), 1.7 mm × 1.25 mm × 0.95 mm - supports high-density PCB layouts with automated placement |
Pinout & Package
SOD323 (SC-76) surface-mount plastic package with 2 leads, 1.3 mm pitch, and cathode identified by a marking bar on the body.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode | Connected to regulated output node; polarity must be observed for correct reverse-bias operation |
| 2 | Anode | Connected to ground or lower-potential rail; completes bias path for Zener conduction |
Key Features
| Feature | Design Value |
|---|---|
| Intentional minor leakage rise | Optimizes fast switching response and reduces noise in regulation loops per AN90031 |
| Hard breakdown knee | Ensures sharp, predictable turn-on at 8.2 V without soft transition or hysteresis |
| Low dynamic impedance | 60 Ω at 5 mA improves line and load regulation stability in feedback networks |
| Small outline footprint | 1.7 mm × 1.25 mm area saves board space in portable and IoT sensor modules |
Applications
| Power Supply Feedback | Overvoltage Clamp |
|---|---|
|
Use Scenario: Regulating output voltage in isolated flyback or buck converter feedback loop using optocoupler-coupled error amplifier. IC Role / Device Role / Timing Role: Provides precise 8.2 V reference to set secondary-side output voltage threshold. Use Value: ±2 % tolerance eliminates need for external resistor trimming; low 60 Ω impedance maintains regulation accuracy under varying optocoupler CTR. |
Use Scenario: Protecting microcontroller I/O pins from ESD or transient overvoltage events on 5 V or 3.3 V signal lines. IC Role / Device Role / Timing Role: Acts as shunt clamp, conducting when input exceeds 8.2 V to divert surge energy to ground. Use Value: 3.5 A non-repetitive peak current rating handles IEC 61000-4-2 Level 4 contact discharge without failure. |
| Reference Voltage Source | Threshold Detection |
|
Use Scenario: Generating stable 8.2 V reference for ADC input scaling or comparator hysteresis in data acquisition front-ends. IC Role / Device Role / Timing Role: Supplies low-noise, temperature-stable voltage to precision analog circuitry. Use Value: +4.6 mV/K temperature coefficient allows predictable compensation; ≤10 nA leakage avoids loading high-impedance sensor nodes. |
Use Scenario: Detecting battery voltage drop below safe operating level in lithium-ion charging management circuits. IC Role / Device Role / Timing Role: Sets 8.2 V threshold for comparator-based undervoltage lockout (UVLO) activation. Use Value: Hard breakdown knee ensures clean, jitter-free switching at threshold; small SOD323 size fits compact battery pack PCBs. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX384-B8V2 | Same 8.2 V, ±2 %, SOD323, but higher typical rdif (80 Ω) and higher IR (50 nA) | Less suitable for ultra-low-power sensing due to higher leakage; acceptable for general-purpose clamping | Select when cost sensitivity outweighs leakage or impedance requirements |
| MMSZ5236B | 8.2 V, ±5 %, SOD123 package (larger, 2.7 mm × 1.6 mm), rdif = 100 Ω, IR = 100 nA | Requires more PCB area; higher leakage increases quiescent current in always-on circuits | Select only if legacy SOD123 footprint compatibility is mandatory |
Compared with PZU8.2B2A,115, BZX384-B8V2 trades tighter thermal stability for higher leakage, while MMSZ5236B sacrifices precision and board space efficiency for broader industry familiarity-neither matches the combination of ±2 % tolerance, 60 Ω impedance, and SOD323 miniaturization.

FAQ
What is the maximum continuous reverse current for PZU8.2B2A,115 at 25 °C ambient?
The device is rated for 200 mA maximum forward current, but as a Zener diode, its continuous reverse current is limited by power dissipation. At 25 °C ambient on an FR4 PCB, 320 mW total power dissipation corresponds to approximately 39 mA continuous reverse current (320 mW ÷ 8.2 V ≈ 39 mA), assuming full regulation voltage drop.
Does PZU8.2B2A,115 meet automotive AEC-Q200 requirements?
No. This part is not AEC-Q200 qualified. Nexperia explicitly states in its legal disclaimers that unless otherwise specified, PZUxBA series devices are non-automotive qualified and not tested to automotive reliability or temperature standards. Use in automotive applications requires customer validation and assumes full liability.
How does the B2 tolerance series differ from B1 or B3 in the PZUxBA family?
B2 denotes ±2 % tolerance at IZ = 5 mA, positioned between B1 (tighter ±2 % with narrower min/max bounds) and B3 (same ±2 % but optimized for higher-voltage types ≥9.1 V). For PZU8.2B2A,115, B2 specifies a 7.76 V to 8.64 V range, verified per Table 8 of the datasheet.
Can PZU8.2B2A,115 be used in parallel for higher power handling?
No. Zener diodes exhibit negative temperature coefficients below ~5 V and positive above, but even within the same batch, slight VZ mismatches cause current hogging. The datasheet does not specify matching or parallel use, and thermal runaway risk makes parallel operation unreliable without individual ballast resistors-defeating the purpose of a compact SOD323 solution.
