Product details
Overview
PDZ7.5BGWJ from Nexperia is a single Zener diode in SOD123 package, designed for precision voltage regulation and overvoltage protection at 7.5 V nominal Zener voltage (VZ = 7.28–7.60 V @ IZ = 5 mA), ±2 % tolerance (B-series), with 365 mW total power dissipation and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the PDZ7.5BGWJ datasheet, PDZ7.5BGWJ pinout, PDZ7.5BGWJ application, or PDZ7.5BGWJ equivalent, this device is selected for low-thermal-resistance (<200 K/W junction-to-solder-point), low-capacitance (170 pF @ 1 MHz), and stable temperature coefficient (+4.0 mV/K) in compact SMD voltage reference and clamp circuits.
Technical Context
This Zener diode operates in reverse breakdown mode with tightly controlled differential resistance (rdif ≤ 60 Ω @ IZ = 5 mA) and low reverse leakage (IR ≤ 0.5 μA @ VR = 5.0 V). Its thermal design supports operation up to 150 °C junction temperature and leverages SOD123's optimized copper pad layout for efficient heat transfer.
The device exhibits a positive temperature coefficient of +4.0 mV/K at IZ = 5 mA - enabling predictable drift compensation in bias networks - and maintains stable capacitance (170 pF) across its operating range, critical for noise-sensitive analog and automotive sensor interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VZ (nominal) | 7.5 V - precise clamping/reference voltage at 5 mA test current |
| Tolerance | ±2 % - tight B-series tolerance ensures minimal binning and system-level calibration burden |
| Ptot | 365 mW - maximum continuous power dissipation on standard FR4 PCB with tin-plated copper |
| rdif | ≤60 Ω - low dynamic impedance ensures stable regulation under load transients |
| IR @ VR = 5.0 V | ≤0.5 μA - ultra-low leakage preserves battery life and signal integrity in standby circuits |
| Cd | 170 pF @ 1 MHz - low junction capacitance minimizes high-frequency coupling in ESD-clamp paths |
| SZ | +4.0 mV/K - predictable positive temperature drift enables accurate thermal compensation |
Pinout & Package
PDZ7.5BGWJ uses the SOD123 surface-mount plastic package (3.75 × 2.55 × 1.3 mm), optimized for automated placement and reflow soldering on FR4 PCBs with defined cathode pad (1 cm²) for thermal performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (marked side) | Cathode (K) | Connected to regulated output or protected node; marking bar identifies this terminal |
| 2 | Anode (A) | Connected to ground or lower-potential rail; reverse-biased configuration enables Zener operation |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C7V5 | Same 7.5 V nominal, ±5 % tolerance, SOT23 package, Ptot = 300 mW | Higher leakage (IR ≤ 0.5 μA same, but rdif = 80 Ω), no AEC-Q101 qualification | Select when cost sensitivity outweighs automotive qualification and tighter tolerance needs |
| MMSZ5235B | 7.5 V nominal, ±5 % tolerance, SOD123 package, Ptot = 500 mW, rdif = 15 Ω | Lower differential resistance but higher leakage (IR ≤ 1.0 μA @ 5 V), not AEC-Q101 qualified | Select when ultra-low impedance is prioritized over leakage and automotive compliance |
Compared with BZX84-C7V5 and MMSZ5235B, PDZ7.5BGWJ uniquely combines ±2 % tolerance, AEC-Q101 qualification, and 60 Ω rdif in SOD123 - making it optimal for automotive and industrial applications requiring both precision and reliability without trade-offs in thermal or surge performance.

FAQ
What is the maximum non-repetitive peak reverse current (IZSM) for PDZ7.5BGWJ?
The maximum non-repetitive peak reverse current is 3.5 A, measured at pulse duration tp = 100 μs and ambient temperature of 25 °C. This value corresponds to the 40 W peak power rating and is validated per IEC 60134 limiting values, supporting transient suppression in automotive and industrial surge environments.
How does the +4.0 mV/K temperature coefficient affect circuit design?
The +4.0 mV/K coefficient means VZ increases by 4.0 mV per Kelvin rise in junction temperature at 5 mA. This predictable positive drift allows firmware-based compensation in precision references or simplifies analog compensation networks - unlike negative-coefficient Zeners that require different correction strategies.
Is PDZ7.5BGWJ compatible with lead-free reflow soldering processes?
Yes - PDZ7.5BGWJ is qualified for lead-free reflow soldering per J-STD-020. Its SOD123 package supports peak temperatures up to 260 °C, and the recommended footprint (4.18 mm × 1.11 mm pad, 0.91 mm solder mask opening) ensures reliable joint formation without tombstoning or voiding.
What is the reverse voltage (VR) at which leakage current reaches 0.5 μA?
At VR = 5.0 V, the reverse current is guaranteed ≤ 0.5 μA. This specification is verified per datasheet Table 8 and defines the usable clamping margin below nominal Zener voltage - critical for designing low-leakage protection circuits in battery-powered systems.
