Product details
Overview
PDZ3.0B,115 from Nexperia is a single silicon Zener diode designed for low-power voltage regulation in compact SMD applications, with a nominal Zener voltage of 3.0 V at 5 mA, ±2 % tolerance, 95 Ω maximum differential resistance at 5 mA, 10 µA maximum reverse current at 1.0 V, and 400 mW total power dissipation on FR4 PCB.
For engineers reviewing the PDZ3.0B,115 datasheet, PDZ3.0B,115 pinout, PDZ3.0B,115 application, or PDZ3.0B,115 equivalent, this device is selected for precision clamping, reference biasing, and overvoltage protection in space-constrained consumer, industrial, and communication circuits where stable low-voltage regulation under low-current conditions is required.
Technical Context
The PDZ3.0B,115 operates as a two-terminal voltage reference diode with hard breakdown knee and low leakage, optimized for operation at IZ = 5 mA. Its −2.1 mV/K temperature coefficient ensures predictable drift across operating temperatures, and its 425 pF capacitance at 1 MHz/0 V supports stable performance in moderate-frequency signal conditioning paths.
Thermal design is constrained by Rth(j-a) = 340 K/W (FR4, single-sided copper), requiring derating above 25 °C ambient; junction temperature must remain ≤150 °C, and non-repetitive peak reverse current is rated at 8.0 A for 100 µs pulses.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 2.85 V to 3.07 V at IZ = 5 mA - defines precise clamping threshold for 3.0 V nominal rail regulation |
| Differential Resistance rdif | ≤95 Ω at IZ = 5 mA - ensures minimal voltage shift under load variation in reference circuits |
| Reverse Current IR | ≤10 µA at VR = 1.0 V - enables low-quiescent-power standby biasing without significant leakage error |
| Forward Voltage VF | ≤0.9 V at IF = 10 mA - supports reliable forward conduction during polarity-reversal protection |
| Total Power Dissipation Ptot | 400 mW at Tamb ≤ 25 °C - sets maximum continuous thermal budget on standard FR4 PCB |
| Temperature Coefficient SZ | −2.1 mV/K at IZ = 5 mA - quantifies predictable negative drift for compensation-aware designs |
| Diode Capacitance Cd | 425 pF at f = 1 MHz, VR = 0 V - impacts high-frequency noise filtering and transient response in clamp networks |
Pinout & Package
PDZ3.0B,115 is housed in a SOD323 (SC-76) surface-mount 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 |
|---|---|---|
| 1 | Cathode (K) | Connected to regulated output node; accepts reverse-bias current to maintain VZ; marked side of package |
| 2 | Anode (A) | Connected to ground or lower-potential rail; completes Zener conduction path during regulation |
Key Features
| Feature | Design Value |
|---|---|
| Low dynamic impedance at low currents | 95 Ω max at 5 mA - improves regulation accuracy in micro-power sensor biasing |
| Hard breakdown knee | Sharp, well-defined Zener transition - reduces ambiguity in clamping onset for overvoltage detection |
| Very low leakage current | 10 µA max at 1.0 V reverse - minimizes parasitic loading in high-impedance reference nodes |
| SOD323 footprint compatibility | Standardized 0.95 mm height, 0.25 mm lead pitch - enables automated placement and reflow on dense PCBs |
| Wide operating temperature range | −65 °C to +150 °C storage; junction limited to +150 °C - supports deployment in extended-environment industrial modules |
Applications
| USB Port ESD Clamp | Microcontroller Reset Circuit |
|---|---|
|

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX384-B3V0,115 | Same SOD323 package, identical 3.0 V nominal VZ, but higher rdif (120 Ω) and looser tolerance (±5 %) | Acceptable where tighter regulation isn't critical and cost sensitivity outweighs precision | Select when BOM cost reduction is prioritized over low-drift performance in non-critical rails |
| MMSZ3V0T1G | Same 3.0 V rating, SOD-123 package (larger footprint), 100 Ω rdif, −2.0 mV/K tempco | Requires PCB layout change; better thermal margin (500 mW rating) but less space-efficient | Choose if thermal headroom > board area constraints, e.g., in high-ambient-temperature motor control modules |
Compared with BZX384-B3V0,115 and MMSZ3V0T1G, PDZ3.0B,115 delivers superior regulation stability (±2 %, 95 Ω rdif) in the smallest footprint, making it optimal for miniaturized, precision-biased systems where leakage and tempco directly impact measurement accuracy.

FAQ
What is the maximum continuous reverse current the PDZ3.0B,115 can sustain without degradation?
The PDZ3.0B,115 is not rated for continuous reverse current; it is designed for regulated Zener conduction at specified test currents (e.g., 5 mA). Continuous operation above its 400 mW power limit-dictated by ambient temperature and PCB thermal design-will exceed junction temperature limits. Derating curves in Figure 1 must be followed to ensure Tj ≤ 150 °C.
Can PDZ3.0B,115 be used in series or parallel configurations for higher voltage or current handling?
No-PDZ3.0B,115 is not characterized for series or parallel use. Zener matching tolerances, tempco mismatches, and thermal coupling effects prevent predictable voltage stacking or current sharing. For higher voltage, select a single-device alternative like PDZ3.3B or PDZ3.6B; for higher power, use a larger-package Zener such as PZU3.0B or BZX84-C3V0.
How does the −2.1 mV/K temperature coefficient affect circuit performance at 85 °C ambient?
At 85 °C ambient (assuming typical PCB thermal resistance), junction temperature rises ~40–60 °C above ambient. With −2.1 mV/K, VZ shifts downward by ~85–125 mV from its 25 °C value-e.g., from 3.0 V to ~2.88–2.92 V. This must be accounted for in reset threshold margins or reference-dependent ADC calibrations.
Is the SOD323 package of PDZ3.0B,115 compatible with standard reflow profiles for lead-free assembly?
Yes-Nexperia specifies full compatibility with IPC/JEDEC J-STD-020D reflow profiles. The recommended solder land pattern (Figure 9) uses 0.6 mm × 0.5 mm pads with 0.5 mm spacing; peak temperature must not exceed 260 °C for ≤10 seconds, and thermal ramp rates must stay within JEDEC limits to avoid package cracking or delamination.
