Product details
Overview
PZU13B1A,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 stable voltage reference in low-power analog monitoring circuits with hard breakdown knee and optimized noise performance per AN90031.
For engineers reviewing the PZU13B1A,115 datasheet, PZU13B1A,115 pinout, PZU13B1A,115 application, or PZU13B1A,115 equivalent, key selection criteria include Zener voltage tolerance (±2 %), differential resistance (≤80 Ω at 5 mA), thermal resistance (255 K/W junction-to-solder point), and SOD323 footprint compatibility for high-density PCB layouts.
Technical Context
This Zener diode operates as a two-terminal shunt voltage reference, maintaining regulation by conducting reverse current above its specified breakdown voltage (13 V nominal). Its design emphasizes low leakage (100 nA at IZ = 0.5 mA) and tight voltage tolerance to support precision biasing in sensor signal chains and power supply feedback networks.
The device uses silicon planar technology with controlled doping to achieve predictable temperature coefficient (±2.5 mV/K typical) and stable dynamic impedance (≤80 Ω at 5 mA). Its SOD323 package enables surface-mount assembly while limiting thermal resistance to 255 K/W (junction-to-solder point) under standard FR4 mounting conditions.
Key Specifications

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 SOD323 package and 13 V rating, but ±5 % tolerance (B series) and higher 200 nA IR at 0.5 mA | Acceptable where cost is prioritized over precision; less suitable for battery-critical or high-accuracy feedback | Select when ±5 % tolerance suffices and legacy BZX384 footprint compatibility is required |
| MMSZ4687T1G | 13 V nominal, ±5 % tolerance, 500 mW Ptot, but larger SOD-123 package (2.7 × 1.6 mm vs. 1.7 × 1.25 mm) | Higher power handling supports higher-current regulation, but occupies 2.3× more board area | Choose only if >320 mW dissipation is needed and layout space permits larger footprint |
Compared with BZX384-B13,115, PZU13B1A,115 offers tighter tolerance and lower leakage for precision biasing; versus MMSZ4687T1G, it trades power margin for 60 % smaller footprint-critical in space-constrained IoT modules.

FAQ
What is the guaranteed Zener voltage range for PZU13B1A,115 at 5 mA test current?
The guaranteed Zener voltage range is 12.74 V to 13.26 V, derived from the nominal 13 V rating with ±2 % tolerance per datasheet Table 8. This specification holds at Tj = 25 °C and applies to all units in the production lot without binning or sorting.
Can PZU13B1A,115 be used in place of a 12 V Zener diode for overvoltage protection?
No-it is not a drop-in replacement for 12 V Zeners due to its fixed 13 V nominal regulation. Using it in a 12 V system would raise the clamping threshold by 1 V, potentially allowing damaging voltages to reach protected circuitry before conduction begins.
How does the intentional leakage current elevation affect circuit noise performance?
Per Application Note AN90031, the controlled increase in reverse current (vs. B-series variants) reduces high-frequency noise by stabilizing carrier injection dynamics at the depletion region edge, making PZU13B1A,115 preferable in audio biasing and RF detector circuits where low phase noise matters.
What is the maximum allowable continuous forward current for PZU13B1A,115?
The absolute maximum forward current is 200 mA per Table 5 (Limiting Values). However, forward conduction is not its intended operating mode; sustained forward bias above 100 mA risks exceeding the 320 mW total power dissipation limit even at room ambient, especially on standard FR4 PCBs.
