Product details
Overview
PZU13B2A,115 from Nexperia is a ±2 % tolerance Zener voltage regulator diode in SOD323 (SC-76) package, rated for 13 V nominal working voltage, 320 mW total power dissipation, and 100 nA reverse current at 0.5 mA test current. It delivers hard breakdown knee characteristics with low dynamic impedance and is optimized for precision voltage reference and overvoltage protection in compact DC power rails.
For engineers reviewing the PZU13B2A,115 datasheet, PZU13B2A,115 pinout, PZU13B2A,115 application, or PZU13B2A,115 equivalent, key selection criteria include Zener voltage tolerance (±2 %), thermal resistance (255 K/W junction-to-solder-point), differential resistance (≤80 Ω at 5 mA), temperature coefficient (±2.5 mV/K), and non-repetitive surge capability (10 A peak reverse current).
Technical Context
This Zener diode operates as a two-terminal shunt voltage reference, maintaining stable regulation across load and line variations via controlled reverse-bias avalanche conduction. Its ±2 % B2 tolerance grade ensures tighter voltage control than standard ±5 % variants, and intentional minor leakage rise improves switching speed and noise immunity per AN90031.
Designed for surface-mount use on FR4 PCBs with single-sided copper, it exhibits 255 K/W junction-to-solder-point thermal resistance under 1 cm² cathode pad conditions and supports pulse surges up to 10 A (100 µs square wave) without degradation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 13 V nominal, min 12.47 V / max 13.96 V at IZ = 5 mA - defines precise regulation point for feedback loops and reference circuits |
| Tolerance Grade | B2 (±2 %) - enables tighter output voltage control vs. B (±5 %) in critical analog or sensing applications |
| Differential Resistance (rdif) | ≤80 Ω at IZ = 5 mA - ensures minimal output voltage shift under varying load currents |
| Reverse Current (IR) | ≤10 nA at VR = 10.4 V - guarantees low standby power loss in battery-backed systems |
| Non-repetitive Peak Reverse Current (IZSM) | 10 A at tp = 100 µs - provides transient overvoltage clamping for ESD and surge events |
| Thermal Resistance (Rth(j-sp)) | 255 K/W - enables reliable operation up to 150 °C junction temperature with standard PCB mounting |
| Total Power Dissipation (Ptot) | 320 mW at Tamb ≤ 25 °C - sets continuous DC power handling limit on standard FR4 layout |
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; polarity marking bar aligns with this terminal for correct PCB orientation |
| 2 | Anode | Connected to ground or lower-potential rail; completes reverse-bias path during regulation |
Key Features
| Feature | Design Value |
|---|---|
| ±2 % Zener voltage tolerance (B2 grade) | Reduces output variation in precision reference designs versus ±5 % alternatives, minimizing calibration overhead |
| Hard breakdown knee | Enables sharp turn-on behavior below 13 V, improving regulation accuracy at light loads and reducing overshoot in clamp circuits |
| Optimized leakage for fast switching | Intentional minor IR increase per AN90031 lowers capacitive time constant, enhancing response to fast transients |
| Low dynamic impedance (≤80 Ω) | Maintains <±10 mV output deviation across 1–10 mA load changes, supporting stable feedback in LDO pre-regulators |
| SOD323 footprint compatibility | Enables high-density placement on space-constrained boards while supporting reflow and wave soldering per IPC-7351B |
Applications
| Power Supply Reference | Overvoltage Clamp |
|---|---|
|
Use Scenario: Providing stable 13 V reference for adjustable DC-DC converter feedback networks in industrial PLC modules. IC Role / Device Role / Timing Role: Shunt voltage reference establishing precise output setpoint independent of input ripple or load variation.

| Temperature-Stable Sensor Bias | Low-Power Voltage Monitor |
|
Use Scenario: Biasing a silicon photodiode in a medical pulse oximeter front-end where signal integrity depends on stable 13 V supply. IC Role / Device Role / Timing Role: Low-noise voltage reference delivering consistent bias despite ambient shifts from 0 °C to 70 °C.

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-B13,115 | Same 13 V nominal, ±2 % tolerance, but SOD323 package with higher rdif (120 Ω) and 200 nA IR | Less stable under dynamic loads; unsuitable for precision references requiring sub-50 mV regulation error | Select only if cost is primary constraint and load current remains <2 mA |
| MMSZ4687T1G | 13 V nominal, ±5 % tolerance (B grade), SOD123 package, 500 mW Ptot, 200 Ω rdif | Larger footprint, looser voltage control, higher power dissipation - better for high-energy clamping, not precision bias | Prefer for ruggedized industrial clamps where board space allows SOD123 and ±5 % tolerance is acceptable |
Compared with BZX384-B13,115 and MMSZ4687T1G, PZU13B2A,115 offers superior regulation stability (80 Ω vs. 120/200 Ω rdif) and lower leakage (10 nA vs. 200 nA), making it optimal for precision analog circuits where voltage accuracy and low quiescent current are critical.

FAQ
What is the maximum continuous reverse power dissipation for PZU13B2A,115?
The maximum continuous total power dissipation is 320 mW at ambient temperature ≤25 °C on an FR4 PCB with single-sided copper and standard footprint. Derating is required above 25 °C per the thermal resistance curve - at 70 °C ambient, usable power drops to approximately 220 mW to maintain 150 °C junction temperature.
How does the B2 tolerance grade differ from B in the PZUxBA series?
B2 denotes ±2 % Zener voltage tolerance at 5 mA test current, whereas B indicates ±5 %. For PZU13B2A,115, this means guaranteed VZ between 12.47 V and 13.96 V, versus 12.35 V to 13.65 V for a B-grade part - a 60 % reduction in voltage spread critical for closed-loop regulation accuracy.
Can PZU13B2A,115 be used in place of a 12 V Zener diode for overvoltage protection?
No - its nominal 13 V Zener voltage and minimum 12.47 V specification exceed typical 12 V rail tolerances. Substituting it for a 12 V device would delay clamping until ~12.5 V, risking damage to downstream 12 V components. Use PZU12B2A,115 (12 V, ±2 %) instead for strict 12 V compliance.
Is PZU13B2A,115 qualified for automotive applications?
No - this device is not AEC-Q200 qualified and lacks automotive-specific testing or qualification documentation. Nexperia explicitly states in its legal disclaimers that non-automotive qualified products are unsuitable for safety-critical or automotive use. For automotive designs, select AEC-Q200-compliant Zeners such as PZU13B2A-Q,115 (if available) or equivalent qualified parts.
