Product details
Overview
PDZ13B,115 from Nexperia is a single silicon Zener diode designed for low-power voltage regulation in compact SMD applications. It provides a nominal 13.2 V Zener voltage at 5 mA test current, with ±2 % tolerance, 80 Ω maximum differential resistance at 5 mA, and 0.1 μA maximum reverse leakage at 10 V. It operates in the SOD323 (SC-76) package and is used in precision reference and overvoltage protection circuits on consumer and industrial PCBs.
For engineers reviewing the PDZ13B,115 datasheet, PDZ13B,115 pinout, PDZ13B,115 application, or PDZ13B,115 equivalent, this device is selected for stable low-current voltage clamping, low-temperature-coefficient biasing, and space-constrained board-level regulation where thermal resistance to solder point (130 K/W) and 400 mW total power dissipation must be factored into layout.
Technical Context
The PDZ13B,115 functions as a two-terminal voltage reference diode operating in reverse breakdown mode. Its Zener voltage is specified at IZ = 5 mA with a typical temperature coefficient of +9.4 mV/K, indicating positive drift with junction temperature - critical for bias network stability across −65 °C to +150 °C storage range.
It exhibits hard breakdown knee behavior and low leakage (≤0.1 μA at VR = 10 V), enabling accurate regulation in low-quiescent-current designs. The device's 103 pF capacitance at 1 MHz and 0 V reverse bias supports moderate-frequency noise filtering without compromising transient response.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 12.91 V to 13.49 V at IZ = 5 mA - defines regulation band for precision 13.2 V reference |
| Differential Resistance rdif | ≤80 Ω at IZ = 5 mA - ensures minimal output voltage shift under load variation |
| Reverse Leakage IR | ≤0.1 μA at VR = 10 V - enables ultra-low standby current in battery-backed circuits |
| Forward Voltage VF | ≤0.9 V at IF = 10 mA - supports reliable anode-cathode polarity verification during ICT |
| Thermal Resistance Rth(j-sp) | 130 K/W - determines junction-to-solder-point temperature rise under 400 mW dissipation |
| Power Dissipation Ptot | 400 mW at Tamb = 25 °C on FR4 PCB - sets maximum continuous DC or pulsed power envelope |
| Capacitance Cd | 103 pF at f = 1 MHz, VR = 0 V - impacts high-frequency bypass effectiveness near regulated node |
Pinout & Package
The PDZ13B,115 is housed in a surface-mount SOD323 (SC-76) plastic package measuring 1.8 mm × 1.35 mm × 0.95 mm, with cathode indicated by a marking bar on the top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX584-C13 | Same 13 V nominal VZ, but ±5 % tolerance and higher 120 Ω rdif | Less precise regulation; suitable only where ±5 % output variation is acceptable | Select when cost sensitivity outweighs regulation accuracy and thermal stability requirements |
| MMSZ5242B | 13 V nominal VZ, ±5 % tolerance, 100 Ω rdif, SOD-123 package (larger footprint) | Higher thermal resistance (400 K/W) limits power handling in dense layouts | Choose only if legacy SOD-123 footprint compatibility is mandatory and derating is applied |
Compared with BZX584-C13 and MMSZ5242B, PDZ13B,115 delivers tighter tolerance, lower dynamic impedance, and superior thermal performance in the smaller SOD323 package - making it optimal for modern miniaturized designs requiring stable 13.2 V references.

FAQ
What is the maximum continuous reverse current the PDZ13B,115 can sustain without degradation?
The PDZ13B,115 has no defined maximum continuous reverse current rating; its operation is governed by power dissipation limits. At 25 °C ambient on an FR4 PCB, it sustains up to 400 mW - corresponding to ~30 mA at 13.2 V Zener voltage. Derating per the curve in Figure 1 applies above 25 °C.
Can PDZ13B,115 be used in series for higher-voltage regulation?
Yes, multiple PDZ13B,115 diodes may be connected in series to achieve higher reference voltages, but mismatched temperature coefficients (+9.4 mV/K each) will compound drift. Parallel connection is not recommended due to unequal current sharing caused by VZ tolerances.
Does the SOD323 package support reflow soldering per JEDEC J-STD-020?
Yes - the PDZ13B,115's SOD323 package is qualified for standard lead-free reflow profiles. Figure 9 specifies the recommended solder land pattern (0.6 mm × 0.5 mm pads, 0.95 mm pitch), and thermal characteristics assume mounting on FR4 with single-sided copper and tin plating.
How does the +9.4 mV/K temperature coefficient affect long-term reference stability?
A +9.4 mV/K coefficient means VZ increases ~122 mV over a 13 °C junction rise. In a 0–70 °C ambient design with self-heating, total drift may reach ±150 mV - requiring compensation in high-accuracy systems or use with temperature-insensitive circuit topologies.
