Product details
Overview
PZU13BA,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 and digital circuits. It delivers a nominal 13 V Zener voltage with ±2 % tolerance (B2 series), 80 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 PZU13BA,115 datasheet, PZU13BA,115 pinout, PZU13BA,115 application, or PZU13BA,115 equivalent, key selection criteria include its tight 13.0–13.96 V working voltage range, low thermal coefficient (±2.5 mV/K), SOD323 footprint compatibility, and suitability for space-constrained DC-DC regulation and ESD-clamped signal conditioning.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain stable voltage under varying load and temperature conditions. Its B2 tolerance grade ensures ±2 % accuracy across production lots, and intentional minor leakage optimization enables faster transient response and reduced noise per AN90031.
The device exhibits hard breakdown knee behavior typical of the PZU5.1BA–10BA subset, but PZU11B2A–51BA variants like PZU13BA,115 trade minimal leakage increase for improved switching fidelity. Thermal resistance from junction to solder point is 55 K/W, enabling reliable operation on standard FR4 PCBs with minimal copper area.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 13.0–13.96 V at IZ = 5 mA; defines precise clamping threshold for 12–15 V rail regulation |
| Differential Resistance rdif | ≤80 Ω at IZ = 5 mA; ensures <130 mV output shift under ±1 mA load variation |
| Reverse Current IR | ≤10 nA at IZ = 0.5 mA; minimizes standby power loss in battery-backed circuits |
| Temperature Coefficient SZ | ±2.5 mV/K; enables predictable drift compensation in temperature-sensitive references |
| Total Power Dissipation Ptot | 320 mW at Tamb ≤ 25 °C on FR4; supports continuous operation in compact SMT layouts |
| Non-repetitive Peak Power PZSM | 40 W for 100 µs pulses; provides robust surge immunity against ESD and line transients |
| Junction Temperature Tj | 150 °C maximum; allows deployment in industrial ambient environments without derating |
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 with bar. Optimized for reflow and wave soldering per Figures 10–11.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode | Connected to regulated output node; marking bar identifies this terminal for correct PCB orientation |
| 2 | Anode | Connected to ground or lower-potential rail; forms reverse-biased junction during regulation |
Key Features
| Feature | Design Value |

| SOD323 footprint compatibility | Matches JEDEC-standard layout for automated placement and reflow, minimizing board redesign effort |
Applications
| Power Supply Feedback Loop | Sensor Bias Reference |
|---|---|
Use Scenario: Regulating output voltage in isolated flyback or buck-derived auxiliary supplies. IC Role / Device Role / Timing Role: Zener diode provides precise voltage reference for optocoupler feedback network. Use Value: Tight 13 V tolerance ensures ±0.26 V output accuracy; low rdif maintains stability under load step changes. |
Use Scenario: Supplying stable bias to analog pressure or temperature transducers. IC Role / Device Role / Timing Role: Acts as shunt reference to set excitation voltage independent of supply ripple. Use Value: ≤10 nA leakage prevents loading of high-impedance sensor outputs; ±2.5 mV/K TC enables predictable calibration. |
| Overvoltage Clamp | ESD-Protected Signal Conditioning |
Use Scenario: Protecting microcontroller I/O pins from transient overvoltage events. IC Role / Device Role / Timing Role: Shunt clamp activated during >13 V surges, diverting current to ground. Use Value: 40 W non-repetitive peak power withstands IEC 61000-4-5 surge pulses; fast knee ensures sub-100 ns response. |
Use Scenario: Front-end protection for RS-485 receivers or ADC inputs exposed to noisy environments. IC Role / Device Role / Timing Role: Low-capacitance (103 pF) Zener placed between signal line and ground to suppress ESD. Use Value: Minimal 103 pF capacitance avoids signal integrity degradation at ≤10 Mbps; optimized leakage reduces baseline offset drift. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C13 | ±5 % tolerance (B grade), 13 V nominal, SOT23 package (larger than SOD323), 90 Ω rdif | Lower accuracy; requires more PCB area; higher thermal resistance (390 K/W j-a) | Select when cost sensitivity outweighs size and precision requirements |
| MMSZ4688T1G | ±5 % tolerance, 13 V nominal, SOD123 package, 100 Ω rdif, 500 mW Ptot | Higher power rating but larger footprint; no B2-grade option available | Choose only if >320 mW continuous dissipation is required and board space permits |
Compared with BZX84-C13 and MMSZ4688T1G, PZU13BA,115 offers superior voltage accuracy (±2 % vs ±5 %), smaller SOD323 footprint, lower dynamic impedance, and purpose-tuned leakage for noise-sensitive regulation - making it optimal for miniaturized, high-stability designs where precision and board area are constrained.

FAQ
What is the exact Zener voltage range for PZU13BA,115 at 5 mA test current?
The confirmed Zener voltage range is 13.0 V to 13.96 V at IZ = 5 mA and Tj = 25 °C, per Table 8 of the Rev. 4 datasheet. This reflects the B2 tolerance grade (±2 %) applied to the nominal 13 V rating, and is validated across production lots without binning or selection.
Can PZU13BA,115 be used in place of a 13 V Zener with ±5 % tolerance?
Yes, but only where tighter regulation is acceptable or beneficial. PZU13BA,115's ±2 % tolerance yields a narrower 13.0–13.96 V window versus ±5 % parts (12.35–13.65 V), reducing output variance in feedback networks. No circuit modification is needed, though layout must accommodate SOD323 instead of SOT23 or DO-35 footprints.
What is the maximum continuous reverse current before thermal runaway occurs?
At 25 °C ambient on standard FR4, the absolute maximum continuous reverse current is 24.6 mA, calculated from Ptot = 320 mW and VZ = 13 V (IZ = Ptot/VZ). Derating is required above 25 °C per the Rth(j-a) = 390 K/W curve; at 85 °C ambient, max continuous IZ drops to ~14 mA.
Does PZU13BA,115 meet automotive AEC-Q200 requirements?
No. The PZUxBA series is not AEC-Q200 qualified. Nexperia explicitly states in Section 14 that unless otherwise specified, these products are non-automotive qualified and unsuitable for safety-critical vehicle systems. For automotive use, consult Nexperia's AEC-Q200-certified Zener portfolio such as the PZUxBL series.
