Product details
Overview
PZU16BA,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 delivers a nominal Zener voltage of 16 V with ±2 % tolerance (B3 series), differential resistance ≤80 Ω at IZ = 5 mA, reverse current ≤20 nA at IZ = 0.5 mA, and operates up to 150 °C junction temperature - commonly used in power supply feedback loops and sensor biasing networks.
For engineers reviewing the PZU16BA,115 datasheet, PZU16BA,115 pinout, PZU16BA,115 application, or PZU16BA,115 equivalent, key selection criteria include its tight 16 V regulation tolerance, low dynamic impedance at low currents, intentional leakage optimization for noise reduction per AN90031, and thermal performance on FR4 PCBs with Rth(j-a) = 390 K/W.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain stable DC voltage under varying load and temperature conditions. Its B3 tolerance grade ensures ±2 % accuracy across the full operating temperature range (−55 °C to +150 °C), and its optimized leakage profile supports fast transient response in regulated power rails.
The device exhibits a positive temperature coefficient of +1.5 mV/K at IZ = 5 mA, enabling predictable drift behavior in temperature-sensitive references. Its 1.7 mm × 1.25 mm × 0.95 mm SOD323 footprint supports high-density PCB layouts while maintaining adequate thermal dissipation for ≤320 mW continuous power.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 16 V nominal, ±2 % tolerance (B3 series) - enables precise 16 V reference generation in feedback networks |
| Differential Resistance (rdif) | ≤80 Ω at IZ = 5 mA - ensures minimal output voltage variation under load current changes |
| Reverse Current (IR) | ≤20 nA at IZ = 0.5 mA - reduces quiescent power loss in battery-powered systems |
| Total Power Dissipation (Ptot) | 320 mW at Tamb ≤ 25 °C on FR4 PCB - defines maximum steady-state power handling in standard layout |
| Non-repetitive Peak Power (PZSM) | 40 W for tp = 100 µs - supports surge suppression during transient overvoltage events |
| Junction Temperature (Tj) | −55 °C to +150 °C - allows operation in industrial and automotive under-hood environments |
| Thermal Resistance (Rth(j-a)) | 390 K/W in free air - determines temperature rise above ambient at given power dissipation |
Pinout & Package
SOD323 (SC-76) plastic surface-mount package: 2-pin, 1.3 mm pitch, 1.7 mm × 1.25 mm × 0.95 mm body; cathode marked by bar on top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode | Connected to regulated output node; polarity must be observed for correct Zener conduction |
| 2 | Anode | Connected to ground or lower-potential rail; forms reverse-biased junction with cathode |
Key Features
| Feature | Design Value |
|---|---|
| ±2 % Zener voltage tolerance (B3) | Enables high-accuracy voltage clamping without post-calibration in production |
| Optimized leakage for noise reduction | Intentional minor IR increase improves switching speed and reduces broadband noise per AN90031 |
| Low dynamic impedance at low currents | Stabilizes reference voltage even at IZ < 1 mA - critical for ultra-low-power sensor interfaces |
| Hard breakdown knee | Sharp turn-on characteristic minimizes regulation hysteresis in feedback control loops |
| FR4-compatible thermal design | Validated Rth(j-sp) = 55 K/W to solder point supports reliable reflow and long-term reliability |
Applications
| Power Supply Feedback Reference | Sensor Biasing Network |
|---|---|
Use Scenario: Regulating output voltage in isolated flyback or buck-boost converters via optocoupler-coupled feedback loop. IC Role / Device Role / Timing Role: Provides stable 16 V reference for TL431 or similar shunt regulator IC input threshold. Use Value: Tight ±2 % tolerance maintains output accuracy within ±1 % over line/load/temperature without trimming. |
Use Scenario: Supplying precise bias current to MEMS pressure sensors or RTD front-ends in portable instrumentation. IC Role / Device Role / Timing Role: Acts as low-noise, low-drift voltage reference for current-source generation. Use Value: Optimized leakage and hard knee reduce measurement noise floor below 10 µVpp in 10 Hz–10 kHz band. |
| Overvoltage Clamp Protection | ADC Input Protection Circuit |
Use Scenario: Protecting microcontroller I/O pins or analog front-end inputs against ESD and supply transients. IC Role / Device Role / Timing Role: Clamps voltage spikes to 16.32 V (max) before damage occurs to downstream silicon. Use Value: 40 W non-repetitive peak power rating absorbs 1 kV ESD pulses per IEC 61000-4-2 Level 4. |
Use Scenario: Limiting input voltage to 16-bit SAR ADC reference buffer to prevent saturation or latch-up. IC Role / Device Role / Timing Role: Functions as fast-acting voltage limiter ahead of op-amp input stage. Use Value: Low 80 Ω rdif ensures clamp voltage stays within 50 mV of nominal during 10 mA fault current. |
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-B16,115 | Same SOD323 package, ±2 % tolerance, but higher rdif (100 Ω vs. 80 Ω) and no AN90031 leakage optimization | Limited suitability in low-noise sensor biasing due to higher dynamic impedance and unoptimized leakage | Prefer when cost sensitivity outweighs noise or transient response requirements |
| MMSZ5245B-TP | SOD-123 package (larger), ±5 % tolerance (B grade), rdif = 17 Ω at 20 mA - not directly comparable at low IZ | Higher power handling (500 mW) but looser tolerance and different thermal profile limits use in compact designs | Select only if board space allows larger footprint and ±5 % regulation error is acceptable |
Compared with BZX384-B16,115 and MMSZ5245B-TP, PZU16BA,115 offers superior low-current regulation stability and purpose-built noise performance, making it optimal for precision analog signal chains where both accuracy and spectral purity matter.

FAQ
What is the maximum continuous reverse current for PZU16BA,115 at 25 °C?
The maximum continuous reverse current is not specified as a standalone parameter; instead, the device is rated for total power dissipation of 320 mW at Tamb ≤ 25 °C. At 16 V Zener voltage, this corresponds to a maximum average reverse current of approximately 20 mA (320 mW ÷ 16 V), assuming no additional forward-bias losses.
Does PZU16BA,115 meet automotive AEC-Q200 requirements?
No - PZU16BA,115 is not AEC-Q200 qualified. The datasheet explicitly states that unless otherwise indicated, Nexperia products are not automotive qualified. This part is intended for industrial, consumer, and computing applications where automotive-grade stress testing and qualification are not required.
How does the B3 tolerance grade differ from B1/B2 in the PZUxBA series?
B3 denotes the tightest tolerance option in the series: ±2 % at IZ = 5 mA and Tj = 25 °C. While B1 and B2 also specify ±2 %, B3 is assigned to types ≥16 V (e.g., PZU16BA–PZU51BA) and reflects tighter binning consistency across voltage and temperature - confirmed in Table 8 and marking code X3 for PZU16BA.
Can PZU16BA,115 be used in parallel for higher power handling?
No - Zener diodes should not be paralleled without individual current-limiting resistors due to mismatched VZ and thermal runaway risk. The PZU16BA,115 datasheet does not recommend or characterize parallel operation; its 40 W non-repetitive rating applies only to single-device surge absorption.
