Product details
Overview
PZU10BA,115 from Nexperia is a general-purpose Zener voltage regulator diode in SOD323 (SC-76) package, designed for precision voltage reference and overvoltage protection in low-power analog circuits. It provides a nominal 10 V Zener voltage with ±5 % tolerance (B-series), 60 Ω maximum differential resistance at IZ = 5 mA, 10 nA reverse current at IZ = 0.5 mA, and operates up to 150 °C junction temperature - commonly used in power supply feedback loops and sensor biasing.
For engineers reviewing the PZU10BA,115 datasheet, PZU10BA,115 pinout, PZU10BA,115 application, or PZU10BA,115 equivalent, key selection criteria include its tight 10 V regulation accuracy, low leakage at sub-mA currents, hard breakdown knee for stable clamping, and compatibility with high-density SMT layouts requiring minimal board area.
Technical Context
This Zener diode operates in reverse-biased breakdown mode to maintain a stable reference voltage across its terminals under varying load and input conditions. Its design emphasizes low dynamic impedance (60 Ω max at 5 mA) and minimal temperature-induced drift (±6.4 mV/K typical at 10 V), enabling reliable performance in voltage monitoring and regulation circuits.
The device features intentional low-leakage behavior per the PZU5.1BA–10BA subgroup, delivering <10 nA reverse current at 0.5 mA test condition and a sharp, well-defined breakdown knee - critical for noise-sensitive analog references and precision threshold detection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 9.5 V to 10.5 V at IZ = 5 mA - ensures ±5 % regulation accuracy for stable 10 V reference generation |
| Differential Resistance (rdif) | ≤60 Ω at IZ = 5 mA - minimizes output voltage variation under load changes in feedback networks |
| Reverse Current (IR) | ≤10 nA at VR = 7.5 V - enables ultra-low power standby operation and high-impedance sensing interfaces |
| Power Dissipation (Ptot) | 320 mW at Tamb ≤ 25 °C on FR4 PCB - supports continuous operation in compact consumer and industrial PCBs |
| Non-repetitive Peak Power (PZSM) | 40 W for tp = 100 µs - provides transient overvoltage suppression capability without thermal runaway |
| Junction Temperature (Tj) | −55 °C to +150 °C - allows deployment in extended-temperature industrial and automotive-adjacent environments |
Pinout & Package
SOD323 (SC-76) surface-mount plastic 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) aligns with this terminal for correct PCB orientation |
| 2 | Anode | Connected to ground or lower-potential rail; forms reverse-biased junction enabling Zener conduction |
Key Features
| Feature | Design Value |
|---|---|
| Hard breakdown knee | Sharp, low-hysteresis Zener transition improves regulation stability in low-current (<1 mA) reference applications |
| Very low leakage current | ≤10 nA at 7.5 V reverse bias reduces error in high-impedance voltage divider and sensor bias networks |
| Low dynamic impedance | 60 Ω max at 5 mA enables <10 mV output shift per 0.6 mA load change - critical for precision feedback paths |
| Thermal stability | Temperature coefficient of +6.4 mV/K at 10 V minimizes drift across −40 °C to +125 °C operating range |
Applications
| Power Supply Feedback Reference | Overvoltage Protection Clamp |
|---|---|

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-B10,115 | Same SOD323 package, ±5 % tolerance, but higher rdif (90 Ω) and higher IR (100 nA at 7.5 V) | Less suitable for ultra-low-power biasing; acceptable for basic clamping where leakage <100 nA is tolerable | Select when cost sensitivity outweighs leakage and impedance requirements |
| MMSZ5240B-7-F | SOD-123 package (larger footprint), same 10 V nominal, ±5 %, but rdif = 17 Ω and IR = 100 nA at 7.5 V | Better dynamic response for fast transients, but incompatible with ultra-dense SMT layouts requiring SOD323 size | Select when lower impedance is prioritized and board space permits larger package |
Compared with BZX384-B10,115, PZU10BA,115 delivers 3× lower leakage and 33 % lower impedance for precision references; versus MMSZ5240B-7-F, it saves 40 % board area while trading 28 % higher rdif for superior layout density.

FAQ
What is the maximum continuous reverse current the PZU10BA,115 can sustain without degradation?
The device supports a maximum continuous forward current of 200 mA per Absolute Maximum Ratings, but as a Zener diode, its rated reverse current is defined by power dissipation limits. At 25 °C ambient on standard FR4 PCB, sustained reverse current must be limited to ≤32 mA to stay within 320 mW total power dissipation - verified by thermal resistance (Rth(j-a) = 390 K/W) and derating curves in the datasheet.
Does the PZU10BA,115 meet automotive AEC-Q200 requirements?
No. The PZU10BA,115 is not AEC-Q200 qualified. Nexperia explicitly states in the legal disclaimers that unless otherwise specified in the datasheet, products are non-automotive qualified and not tested to automotive reliability or temperature standards. For automotive use, engineers must select designated AEC-Q200-compliant Zener variants such as PZU10BA-Q.
How does the temperature coefficient affect regulation accuracy over −40 °C to +125 °C?
At 10 V nominal, the PZU10BA,115 exhibits a typical temperature coefficient of +6.4 mV/K. Over a 165 K span, this results in approximately ±1.06 V total drift - meaning regulation shifts from ~8.94 V at −40 °C to ~11.06 V at +125 °C. This is confirmed in Figure 4 of the datasheet and must be accounted for in wide-temperature applications.
Can PZU10BA,115 be used in parallel for higher power handling?
No. Parallel connection of Zener diodes is not recommended due to mismatched breakdown voltages and thermal runaway risk. Even minor VZ variations cause current hogging in one device. For higher power, use a single higher-rated Zener (e.g., PZU10B2A with 2 % tolerance and same package) or add an external series transistor - as detailed in Nexperia Application Note AN90031.
