Product details
Overview
PZU30BA,115 from Nexperia is a general-purpose Zener voltage regulator diode in SOD323 (SC-76) package, providing precise 30 V nominal regulation at 5 mA with ±5 % tolerance, 200 Ω maximum differential resistance, and 40 µA reverse current at 0.5 mA test condition-used for voltage reference and overvoltage protection in low-power analog circuits.
For engineers reviewing the PZU30BA,115 datasheet, PZU30BA,115 pinout, PZU30BA,115 application, or PZU30BA,115 equivalent, this device supports stable DC biasing, precision clamping, and low-leakage voltage referencing in space-constrained PCB layouts requiring tight thermal resistance control and fast transient response.
Technical Context
This Zener diode operates in reverse breakdown mode with a hard knee characteristic optimized for low-current regulation stability. Its temperature coefficient of +1 mV/K at 30 V enables predictable drift compensation in ambient-temperature-varying circuits.
The device delivers 320 mW total power dissipation on FR4 PCB with single-sided copper and exhibits 255 K/W junction-to-solder-point thermal resistance-critical for thermal management in compact power-supply feedback networks and sensor signal conditioning stages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Zener Voltage (VZ) | 30 V at IZ = 5 mA - defines regulated output level in shunt reference applications |
| Tolerance | ±5 % (B series) - sets absolute accuracy band for voltage-sensitive circuit calibration |
| Differential Resistance (rdif) | 200 Ω max at IZ = 5 mA - determines regulation stiffness under load variation |
| Reverse Current (IR) | 40 µA max at VR = 28 V - ensures minimal leakage in high-impedance bias networks |
| Total Power Dissipation (Ptot) | 320 mW at Tamb ≤ 25 °C - establishes continuous operating limit on standard FR4 PCB |
| Non-repetitive Peak Power (PZSM) | 40 W at tp = 100 µs - supports surge suppression in transient-overvoltage events |
| Junction Temperature (Tj) | 150 °C max - defines upper thermal boundary for reliability in sealed enclosures |

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-B30,115 | Same 30 V, ±5 %, SOD323 package but higher rdif (500 Ω max) and 100 µA IR | Less suitable for low-current precision references; better for general-purpose clamping | Select when cost sensitivity outweighs regulation stiffness requirements |
| MMSZ5256ET1G | 30 V, ±5 %, SOD-123 package (larger), 100 Ω rdif, 100 nA IR at 25 V | Lower leakage enables ultra-high-impedance nodes but requires more board area | Select when sub-µA leakage dominates over footprint constraints |
Compared with PZU30BA,115, BZX384-B30,115 trades regulation precision for broader availability, while MMSZ5256ET1G improves leakage performance at the expense of PCB real estate-making PZU30BA,115 optimal for space-constrained, medium-accuracy 30 V reference designs.

FAQ
What is the maximum continuous reverse current for PZU30BA,115 at 30 V?
The device is rated for 5 mA Zener test current, with maximum continuous reverse current limited by its 320 mW power dissipation: at 30 V, this yields 10.7 mA absolute maximum under ideal thermal conditions. Derating is required above 25 °C ambient per the 255 K/W junction-to-solder-point thermal resistance.
Does PZU30BA,115 meet automotive AEC-Q200 requirements?
No. PZU30BA,115 is not AEC-Q200 qualified. Nexperia explicitly states in its legal disclaimers that non-automotive qualified products like this Zener diode are unsuitable for automotive use and lack qualification testing per automotive reliability standards.
How does the +1 mV/K temperature coefficient affect circuit accuracy over –40 °C to +125 °C?
At ±100 K deviation from 25 °C, the coefficient contributes ±100 mV shift in VZ. For a 30 V nominal device, this represents ±0.33 % full-scale drift-within acceptable bounds for non-precision industrial references but insufficient for metrology-grade applications.
Can PZU30BA,115 be used in parallel for higher power handling?
No. Zener diodes exhibit negative temperature coefficients below ~5 V and positive above, but even within the same batch, minor VZ mismatches cause current hogging. Parallel operation is not recommended; instead, use a single higher-rated device or active regulation.
