Product details
Overview
PDZ5.1BGWX from Nexperia is a single Zener diode in SOD123 package, designed for precision voltage regulation and reference applications with nominal Zener voltage 5.1 V at 5 mA, ±2 % tolerance (B-series), 250 Ω max differential resistance, and 2 μA max reverse current at 3.8 V. It delivers stable clamping in low-power analog circuits, ESD-protected I/O rails, and automotive sensor biasing.
For engineers reviewing the PDZ5.1BGWX datasheet, PDZ5.1BGWX pinout, PDZ5.1BGWX application, or PDZ5.1BGWX equivalent, this device supports AEC-Q101 qualified designs requiring tight voltage tolerance, low thermal drift (SZ = +0.3 mV/K), and robust surge handling (IZSM = 5.5 A, PZSM = 40 W).
Technical Context
This Zener operates in reverse breakdown mode with tightly controlled VZ = 4.96–5.20 V at IZ = 5 mA, enabling accurate voltage referencing in feedback loops and overvoltage protection circuits. Its low rdif (≤250 Ω) ensures minimal dynamic impedance variation under load changes.
Thermal performance is defined by Rth(j-a) = 340 K/W (free air) and Rth(j-sp) = 200 K/W (solder point), supporting reliable operation up to Tj = 150 °C. The cathode-marked SOD123 footprint enables compact, high-density PCB layouts compatible with standard reflow profiles.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 4.96–5.20 V at IZ = 5 mA - defines precise clamping threshold for 5 V rail stabilization |
| Tolerance | ±2 % (B-series) - enables high-accuracy voltage references without trimming |
| Differential Resistance (rdif) | ≤250 Ω - ensures stable regulation under varying load currents |
| Reverse Current (IR) | ≤2 μA at VR = 3.8 V - minimizes leakage in battery-powered standby circuits |
| Non-repetitive Peak Current (IZSM) | 5.5 A (tp = 100 μs) - provides transient overvoltage immunity per IEC 61000-4-5 |
| Thermal Resistance (Rth(j-sp)) | 200 K/W - allows 150 °C junction operation with ≤125 °C board temperature rise |
| Temperature Coefficient (SZ) | +0.3 mV/K at IZ = 5 mA - near-zero drift enables stable reference across −40 to +125 °C |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX584-C5V1 | VZ = 4.9–5.3 V (±5 %), rdif ≤ 90 Ω, IR ≤ 10 μA @ 3.8 V | Higher leakage and wider tolerance; suitable only for non-critical regulation | Select when cost sensitivity outweighs precision and leakage requirements |
| MMSZ5231B | VZ = 4.76–4.94 V (±5 %), rdif ≤ 17 Ω, IR ≤ 1 μA @ 3.5 V, SOD-123 package | Lower nominal voltage and tighter rdif, but no AEC-Q101 qualification | Prefer for industrial consumer designs where automotive qualification is not required |
Compared with BZX584-C5V1 and MMSZ5231B, PDZ5.1BGWX uniquely combines AEC-Q101 qualification, ±2 % tolerance, and +0.3 mV/K temperature coefficient-making it the only choice for automotive-grade 5.1 V reference where long-term stability and regulatory compliance are mandatory.

FAQ
What is the maximum continuous power dissipation for PDZ5.1BGWX at 25 °C ambient?
PDZ5.1BGWX has a total power dissipation (Ptot) of 365 mW at Tamb ≤ 25 °C on standard FR4 PCB with single-sided copper and tin-plated finish. Derating begins above 25 °C at 3.2 mW/°C based on thermal resistance of 340 K/W.
How is the cathode identified on the PDZ5.1BGWX SOD123 package?
The cathode (pin 1) is marked by a visible bar on the top surface of the SOD123 package. This marking aligns with the cathode symbol in the simplified outline diagram and must be oriented toward the regulated output node during PCB layout.
Does PDZ5.1BGWX support reflow soldering only, or can it be hand-soldered?
Reflow soldering is the only recommended method per Nexperia's documentation. Hand-soldering is not advised due to thermal stress risks; the device's maximum junction temperature is 150 °C, and localized iron contact may exceed safe thermal limits even briefly.
What is the significance of the 'B' in PDZ5.1BGWX's part number?
The 'B' denotes the ±2 % Zener voltage tolerance grade per E24 series, confirmed in Table 8 of the datasheet. It distinguishes PDZ5.1BGWX from broader-tolerance variants (e.g., 'A' = ±5 %) and directly impacts reference accuracy in closed-loop systems.
