Product details
Overview
PDZ2.7BGWX from Nexperia is a single Zener diode in SOD123 package, designed for precision voltage regulation and reference applications at 2.7 V nominal Zener voltage with ±2 % tolerance (B-series), 20 μA max reverse current at 1 V, 1.0 Ω typical differential resistance at IZ = 5 mA, and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the PDZ2.7BGWX datasheet, PDZ2.7BGWX pinout, PDZ2.7BGWX application, or PDZ2.7BGWX equivalent, this device supports low-power voltage clamping, overvoltage protection, and stable biasing in space-constrained SMT designs where tight Zener voltage tolerance, low thermal drift, and automotive qualification are required.
Technical Context
This Zener diode operates in reverse breakdown mode with a nominal working voltage of 2.7 V at IZ = 5 mA, exhibiting a negative temperature coefficient of −2.0 mV/K at that current. Its differential resistance remains low (≤1.0 Ω) to maintain regulation stability under varying load conditions.
The device is rated for total power dissipation up to 365 mW at Tamb ≤ 25 °C on standard FR4 PCB, with non-repetitive peak reverse power handling of 40 W (100 μs pulse), and junction temperature limited to 150 °C - enabling robust transient suppression in automotive and industrial environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 2.69 V to 2.91 V at IZ = 5 mA - ensures precise 2.7 V regulation within ±2 % tolerance for reference and feedback circuits. |
| Differential Resistance rdif | ≤1.0 Ω at IZ = 5 mA - minimizes output voltage variation under dynamic load changes in regulator loops. |
| Reverse Current IR | ≤20 μA at VR = 1 V - guarantees low leakage in high-impedance bias networks and battery-powered systems. |
| Power Dissipation Ptot | 365 mW at Tamb ≤ 25 °C - supports continuous operation in compact SMT layouts without forced cooling. |
| Thermal Resistance Rth(j-a) | 340 K/W in free air - defines derating curve for ambient temperature rise above 25 °C in unmounted or low-copper PCB scenarios. |
| Temperature Coefficient SZ | −2.0 mV/K at IZ = 5 mA - enables predictable voltage drift compensation in temperature-sensitive analog references. |
| AEC-Q101 Qualified | Qualified per Automotive Electronics Council stress test standard - validated for use in automotive ECUs, body control modules, and infotainment power rails. |
Pinout & Package
SOD123 surface-mount plastic package: 2.80 mm × 1.70 mm footprint, 1.3 mm height, cathode marked by bar on top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to regulated output node; polarity must be observed for correct reverse-bias operation and voltage clamping direction. |
| 2 (A) | Anode | Connected to ground or lower-potential rail; forms the reference return path during Zener conduction. |
Key Features
| Feature | Design Value |
|---|---|
| ±2 % Zener voltage tolerance (B-series) | Enables tighter regulation accuracy than standard ±5 % Zeners, reducing need for post-production trimming in feedback networks. |
| Low differential resistance (≤1.0 Ω) | Maintains stable Zener voltage across 1–10 mA operating range, critical for precision shunt regulators and ADC reference buffers. |
| AEC-Q101 qualification | Validated for automotive temperature cycling, humidity, and mechanical shock - suitable for under-hood and dashboard electronics without additional qualification effort. |
| Non-repetitive peak power: 40 W | Withstands ESD transients and load-dump spikes up to 100 μs duration, eliminating need for external TVS in many 12 V system protection schemes. |
| Small SOD123 footprint | Reduces PCB area by >40 % vs. DO-35 or SOD-323 packages, supporting high-density automotive and portable power management layouts. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX384-B2V7 | Same 2.7 V ±2 %, SOD323 package, 200 mW Ptot, no AEC-Q101 qualification | Limited to commercial/industrial use; unsuitable for automotive due to missing stress qualification | Select when cost and board space are primary concerns and automotive qualification is not required. |
| MMSZ4678T1G | 2.7 V ±5 %, SOD123 package, 500 mW Ptot, AEC-Q101 qualified, higher leakage (50 μA @ 1 V) | Looser voltage tolerance increases reference error; higher power rating suits higher-current clamping | Choose when higher surge energy absorption is needed and ±5 % regulation accuracy is acceptable. |
Compared with BZX384-B2V7, PDZ2.7BGWX offers automotive qualification and identical tolerance in same footprint; versus MMSZ4678T1G, it delivers tighter regulation and lower leakage at the expense of lower absolute power rating - making it optimal for precision, low-power automotive sensing nodes.

FAQ
What is the maximum continuous reverse current this Zener can handle at 2.7 V?
The PDZ2.7BGWX is specified for Zener test current IZ = 5 mA, with maximum continuous reverse current limited by power dissipation: at 25 °C ambient, 365 mW / 2.7 V ≈ 135 mA. Derating applies above 25 °C per the 340 K/W thermal resistance - actual usable current depends on PCB copper area and airflow.
Does the SOD123 package support reflow soldering only, or can it be hand-soldered?
Nexperia specifies reflow soldering as the only recommended method for PDZ2.7BGWX. Hand-soldering is not advised due to thermal stress risks: the SOD123's small thermal mass makes it susceptible to overheating (>260 °C peak) during iron contact, potentially degrading Zener characteristics or delaminating the mold compound.
How does the −2.0 mV/K temperature coefficient affect circuit performance over −40 °C to +125 °C?
Over that range, the Zener voltage shifts by approximately −2.0 mV/K × 165 K = −330 mV - from ~2.87 V at −40 °C to ~2.54 V at +125 °C. This drift must be accounted for in precision references; however, its linearity enables first-order compensation in analog front-ends using matched NTC thermistors or digital lookup tables.
Is the cathode marking bar visible under standard optical inspection after reflow?
Yes - the cathode bar is laser-marked on the top surface of the SOD123 package and remains clearly visible post-reflow under 10× magnification. The marking conforms to JEDEC standards and aligns with the pin 1 indicator in IPC-7351 land patterns, enabling automated optical inspection (AOI) and manual verification during rework.
