Product details
Overview
PZU10B1A,115 from Nexperia is a ±2 % tolerance Zener voltage regulator diode in SOD323 (SC-76) package, rated for 10 V nominal working voltage, 320 mW total power dissipation at 25 °C ambient, and 40 W non-repetitive peak reverse power. It delivers low dynamic impedance (60 Ω max at IZ = 5 mA), tight leakage control (10 nA max at IZ = 0.5 mA), and optimized noise performance for precision reference and regulation in compact power management circuits.
For engineers reviewing the PZU10B1A,115 datasheet, PZU10B1A,115 pinout, PZU10B1A,115 application, or PZU10B1A,115 equivalent, key selection criteria include Zener voltage tolerance (±2 %), differential resistance at low current, thermal resistance to solder point (255 K/W), and SC-76 footprint compatibility with high-density PCB layouts.
Technical Context
This Zener diode operates as a two-terminal shunt voltage reference, maintaining stable reverse-biased conduction across its specified working current range (IZ = 0.5 mA to 5 mA). Its hard breakdown knee and intentional minor leakage rise support fast transient response and reduced output noise in feedback loops.
Designed for surface-mounted use on FR4 PCBs with single-sided copper, it exhibits Rth(j-sp) = 255 K/W and Rth(j-a) = 390 K/W, enabling reliable thermal performance up to 150 °C junction temperature under defined mounting conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VZ nominal | 10 V - precise regulation target at IZ = 5 mA, ±2 % tolerance ensures tight voltage stability in reference circuits |
| Ptot | 320 mW - maximum continuous power dissipation on standard FR4 PCB, defining safe DC operating envelope |
| PZSM | 40 W - non-repetitive surge capability for 100 µs square-wave transients, supporting overvoltage protection duty cycles |
| rdif | 60 Ω max at IZ = 5 mA - low dynamic impedance enables minimal output voltage variation under load changes |
| IR | 10 nA max at VR = 7.5 V - ultra-low reverse leakage preserves accuracy in high-impedance bias networks |
| Tj max | 150 °C - absolute maximum junction temperature, constraining thermal design margin for long-term reliability |
| Cd | 110 pF at f = 1 MHz, VR = 0 V - junction capacitance impacts high-frequency noise filtering and stability in AC-coupled references |
Pinout & Package
The PZU10B1A,115 is housed in a SOD323 (SC-76) plastic surface-mount package measuring 1.7 mm × 1.25 mm × 0.95 mm, with 1.3 mm lead pitch and cathode-marked body.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode | Connected to regulated output node; marking bar identifies this terminal for correct PCB orientation and polarity-sensitive placement |
| 2 | Anode | Connected to ground or lower-potential rail; forms the reference return path and completes the shunt regulation loop |
Key Features
| Feature | Design Value |
|---|---|
| ±2 % Zener voltage tolerance | Enables tighter regulation accuracy than ±5 % variants, reducing need for post-calibration in precision analog supplies |
| Very low dynamic impedance (60 Ω) | Maintains <1 % output deviation under ±1 mA load current shifts, critical for stable feedback in LDO pre-regulators |
| Optimized leakage profile | Intentional minor IR rise improves switching speed and reduces broadband noise-verified per AN90031 for clean reference generation |
| SOD323 footprint | 1.7 mm × 1.25 mm body supports high-density routing in space-constrained IoT sensor nodes and portable power modules |
| Hard breakdown knee | Ensures sharp turn-on characteristic at 10 V, minimizing ambiguity in threshold detection for undervoltage lockout circuits |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX384-B10,115 | Same SOD323 package and 10 V ±2 % rating, but higher rdif (90 Ω max) and higher IR (50 nA max at 7.5 V) | Less suitable for ultra-low-power sensor biasing where leakage-induced offset matters | Select when cost sensitivity outweighs leakage and impedance requirements |
| MMSZ5240B-7-F | SOD-123 package (larger footprint), same 10 V ±5 % rating, rdif = 17 Ω, but no optimized noise/leakage profile | Better for high-current regulation (>20 mA), not recommended for noise-sensitive references | Choose only if board layout allows larger package and ±5 % tolerance is acceptable |
Compared with BZX384-B10,115 and MMSZ5240B-7-F, PZU10B1A,115 offers superior low-current regulation fidelity (60 Ω rdif, 10 nA IR) and noise-optimized behavior-making it preferred for precision analog, low-power, and high-density designs where SOD323 fit is mandatory.

FAQ
What is the maximum continuous reverse current for PZU10B1A,115 at 25 °C ambient?
The device has no specified maximum continuous reverse current; instead, its safe operating area is defined by total power dissipation (320 mW at Tamb ≤ 25 °C on FR4 PCB). At 10 V Zener voltage, this corresponds to a maximum average reverse current of 32 mA under those thermal conditions.
Does PZU10B1A,115 meet automotive AEC-Q200 requirements?
No. The PZU10B1A,115 is not AEC-Q200 qualified. Nexperia explicitly states in its legal disclaimers that unless otherwise stated in the datasheet, products are non-automotive qualified and unsuitable for safety-critical or automotive applications.
How does the "B1" suffix affect electrical behavior versus "B" or "B2"?
The "B1" suffix denotes ±2 % Zener voltage tolerance (vs. ±5 % for "B", ±2 % for "B2"/"B3"). For PZU10B1A,115, this means VZ is guaranteed between 9.8 V and 10.2 V at IZ = 5 mA-tighter than B-series (9.5–10.5 V) and identical in tolerance to B2/B3, though B2/B3 variants may differ in leakage or impedance profiles per voltage grade.
Can PZU10B1A,115 be used in parallel for higher power handling?
No. Zener diodes exhibit negative temperature coefficients below ~5 V and positive above, causing current hogging and thermal runaway when paralleled. The datasheet provides no derating guidance or test data for parallel operation, and thermal coupling in SOD323 packages makes balanced sharing impractical.
