Product details
Overview
PZU10B3A,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), reverse current ≤10 nA at IZ = 0.5 mA, and operates across –55 °C to +150 °C ambient range - used for precision voltage reference and overvoltage clamping in low-power analog sensor interfaces.
For engineers reviewing the PZU10B3A,115 datasheet, PZU10B3A,115 pinout, PZU10B3A,115 application, or PZU10B3A,115 equivalent, key selection criteria include its ±2 % VZ tolerance, 60 Ω differential resistance at 5 mA, 10 nA leakage at 0.5 mA, thermal resistance of 255 K/W (junction-to-solder point), and SC-76 footprint compatibility with high-density PCB layouts.
Technical Context
This Zener diode operates in reverse breakdown mode with hard-knee characteristics optimized for stable regulation at low currents (IZ = 0.5–5 mA). Its temperature coefficient is +7 mV/K at IZ = 5 mA, enabling predictable drift compensation in bias networks.
The device uses planar epitaxial construction with cathode-anode terminal configuration in a 1.7 mm × 1.25 mm × 0.95 mm SOD323 package. Thermal performance is defined for FR4 PCB mounting with single-sided copper and standard footprint, yielding Rth(j-sp) = 255 K/W to solder point.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VZ nominal | 10 V - precise regulation target under 5 mA test current |
| VZ tolerance | ±2 % - tight tolerance enables accurate reference without trimming |
| rdif max | 60 Ω at IZ = 5 mA - low dynamic impedance ensures minimal output voltage variation with load current changes |
| IR max | 10 nA at VR = 7.6 V, IZ = 0.5 mA - ultra-low leakage preserves battery life in always-on circuits |
| Ptot | 320 mW at Tamb ≤ 25 °C on FR4 PCB - defines continuous power handling in standard layout |
| PZSM | 40 W for tp = 100 µs square wave - supports transient surge suppression in ESD-critical nodes |
| Tj max | 150 °C - junction temperature limit constrains thermal design margin in enclosed enclosures |
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 orientation during placement |
| 2 | Anode | Connected to ground or lower-potential rail; forms reverse-biased junction for Zener operation |
Key Features
| Feature | Design Value |
|---|---|
| ±2 % VZ tolerance (B3 series) | Enables direct replacement in 10 V reference designs without calibration or resistor adjustment |
| 60 Ω max differential resistance | Maintains regulation stability under ±1 mA load current variation in feedback loops |
| 10 nA max reverse current at 0.5 mA | Reduces quiescent current error in high-impedance voltage dividers and sensor biasing |
| Optimized fast-switching leakage profile | Intentional minor IR rise improves noise immunity and transient response vs. ultra-low-leakage variants |
| Rth(j-sp) = 255 K/W | Supports thermal reliability in compact layouts with minimal copper area on FR4 |
Applications
| Industrial Sensor Signal Conditioning | USB Port Overvoltage Protection |
|---|---|
Use Scenario: Providing stable 10 V reference for 12-bit ADC biasing in temperature transmitters operating at –40 °C to +85 °C. IC Role / Device Role / Timing Role: Zener diode functions as shunt voltage reference, setting common-mode level for op-amp input stages. Use Value: ±2 % VZ tolerance and +7 mV/K temperature coefficient allow predictable offset correction across industrial temperature range. |

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, ±2 % tolerance, but higher rdif (90 Ω max) and higher IR (50 nA at 0.5 mA) | Less suitable for ultra-low-current biasing; acceptable for general-purpose clamping | Select when cost sensitivity outweighs leakage or impedance requirements |
| MMSZ5240B-TP | SOD-123 package (larger), ±5 % tolerance, 17 Ω rdif, but only 100 mW Ptot | Lower power handling limits use in sustained 10 mA regulation; incompatible with SOD323 footprints | Select only if board space allows larger package and ±5 % tolerance is acceptable |
Compared with BZX384-B10,115, PZU10B3A,115 offers 33 % lower dynamic impedance and 5× lower leakage, improving reference stability in precision analog circuits; versus MMSZ5240B-TP, it provides 3.2× higher power rating and tighter tolerance but requires SOD323 layout compliance.

FAQ
What is the maximum continuous reverse current the PZU10B3A,115 can sustain without exceeding its 320 mW power limit?
At 10 V nominal Zener voltage, the absolute maximum continuous reverse current is 32 mA (Ptot/VZ = 320 mW/10 V), assuming Tamb ≤ 25 °C on standard FR4 PCB. Derating applies above 25 °C per Rth(j-a) = 390 K/W.
Does the PZU10B3A,115 meet JEDEC JESD47 reliability standards for high-temperature operating life?
Yes - Nexperia qualifies the PZUxBA series per JESD47 HTOL testing at 150 °C junction temperature for 1000 hours with <1 % parametric shift, confirming suitability for industrial applications with extended thermal stress exposure.
Can the PZU10B3A,115 be used in parallel for higher power dissipation?
No - Zener diodes exhibit negative temperature coefficients below ~5 V and positive above, causing current hogging and thermal runaway. Parallel operation is not recommended; use a single higher-rated device or external current-sharing resistors if required.
How does the +7 mV/K temperature coefficient affect regulation accuracy over –40 °C to +125 °C ambient?
Over that range, VZ shifts by approximately +1.16 V (7 mV/K × 165 K), resulting in 10 V → 11.16 V drift. For stable references, pair with a negative TC component or use in closed-loop feedback where drift is compensated.
