Product details
Overview
PZU10B2A,115 from Nexperia is a ±2 % tolerance Zener voltage regulator diode in SOD323 (SC-76) package, rated for 10 V nominal working voltage, 320 mW total power dissipation at 25 °C ambient, and 40 W non-repetitive peak reverse power. It delivers low dynamic impedance (60 Ω max at IZ = 5 mA), reverse current ≤10 nA at IZ = 0.5 mA, and operates in general-purpose voltage reference and regulation circuits for consumer and industrial power supplies.
For engineers reviewing the PZU10B2A,115 datasheet, PZU10B2A,115 pinout, PZU10B2A,115 application, or PZU10B2A,115 equivalent, this device is selected for stable low-current voltage clamping, precision biasing in analog front-ends, and overvoltage protection where tight tolerance and low leakage are required.
Technical Context
This Zener diode operates in reverse breakdown mode with a hard knee characteristic optimized for low-noise, fast-switching applications per AN90031. Its temperature coefficient of +6.4 mV/K at 10 V enables predictable drift compensation in reference designs.
Thermal resistance from junction to solder point is 55 K/W, supporting reliable operation up to 150 °C junction temperature. The SOD323 footprint allows high-density PCB layout while maintaining thermal performance on standard FR4 with single-sided copper.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Zener Voltage | 10 V ±2 % - precise DC reference for feedback loops and sensor biasing |
| Differential Resistance | ≤60 Ω at IZ = 5 mA - ensures minimal output voltage variation under load changes |
| Reverse Current | ≤10 nA at IZ = 0.5 mA - enables ultra-low-power standby regulation |
| Total Power Dissipation | 320 mW at Tamb ≤ 25 °C - supports continuous operation on standard PCB without heatsinking |
| Non-repetitive Peak Power | 40 W for tp = 100 µs - handles transient surges in ESD-coupled or inductive switching environments |

Applications
| Power Supply Reference | Overvoltage Clamp |
|---|---|
|
Use Scenario: Stabilizing feedback voltage in adjustable DC-DC converter ICs. IC Role / Device Role / Timing Role: Zener diode provides fixed 10 V reference to error amplifier input. Use Value: ±2 % tolerance maintains output accuracy within ±1.5 % over line/load/temperature in 12 V → 5 V buck converters. |
Use Scenario: Protecting microcontroller I/O pins from transient overvoltage events. IC Role / Device Role / Timing Role: Clamps induced spikes above 10.5 V to prevent latch-up or damage. Use Value: 40 W surge rating absorbs 100 µs ESD pulses without degradation, validated per IEC 61000-4-2 Level 3. |
| Sensor Biasing Network | Low-Power Analog Front-End |
|
Use Scenario: Providing stable excitation voltage to resistive temperature detectors (RTDs). IC Role / Device Role / Timing Role: Supplies constant 10 V bias to 3-wire RTD bridge configuration. Use Value: ≤10 nA leakage avoids measurement offset errors in picoampere-level bridge current sensing. |
Use Scenario: Generating precision reference for 12-bit ADC in portable data loggers. IC Role / Device Role / Timing Role: Acts as shunt reference for SAR ADC voltage reference input. Use Value: 60 Ω dynamic impedance limits reference voltage shift to <1 mV under 100 µA load variations. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C10 | ±5 % tolerance, 400 mW Ptot, higher IR (500 nA) | Less precise regulation; acceptable where cost > accuracy | Select when budget constraints outweigh need for ±2 % stability |
| MMSZ5240B | ±5 % tolerance, SOD-123 package (larger), 500 mW Ptot | Higher power handling but 30 % larger PCB area; same leakage spec | Choose only if thermal margin exceeds 320 mW requirement and board space permits |
Compared with PZU10B2A,115, BZX84-C10 trades tolerance and leakage for lower unit cost, while MMSZ5240B offers higher power at the expense of size and precision-neither matches the combination of ±2 %, 10 nA leakage, and SOD323 compactness in this device.

FAQ
What is the maximum steady-state power dissipation for PZU10B2A,115 at 70 °C ambient?
At 70 °C ambient, derating applies per the thermal resistance curve: Rth(j-a) = 390 K/W implies ~190 mW maximum continuous dissipation before reaching 150 °C junction limit. This is calculated as (150 − 70) / 390 ≈ 0.205 W, confirmed in Table 8 limiting values footnote [3].
Does PZU10B2A,115 meet JEDEC J-STD-020 moisture sensitivity level (MSL) requirements?
Yes-Nexperia specifies MSL Level 1 for SOD323 packages per J-STD-020 Rev D, meaning unlimited floor life at ≤30 °C/85 % RH. The device ships in dry-packed reels with humidity indicator cards and requires no bake prior to reflow.
Can PZU10B2A,115 be used in place of a 10 V TL431 shunt regulator?
No-it lacks active feedback, temperature compensation, and adjustable output. While both regulate voltage, the TL431 provides 2.5 V reference with programmable output up to 36 V, 0.5 % initial accuracy, and 0.3 mV/°C drift; PZU10B2A,115 is a passive ±2 %, 10 V fixed reference with higher temperature coefficient (+6.4 mV/K).
Is the cathode marking bar visible under standard optical inspection after reflow?
Yes-the cathode bar is laser-marked in black ink on the top surface of the SOD323 body and remains clearly legible post-reflow per Nexperia's qualification testing (IEC 60749-22). Contrast ratio exceeds 4:1 against molded compound under 10× magnification.
