Product details
Overview
PDZ7.5BGWX from Nexperia is a single Zener diode in SOD123 package, designed for precision voltage regulation and reference functions with nominal Zener voltage 7.5 V at 5 mA, ±2 % tolerance (B-series), 60 Ω max differential resistance, and AEC-Q101 qualification for automotive environments.
For engineers reviewing the PDZ7.5BGWX datasheet, PDZ7.5BGWX pinout, PDZ7.5BGWX application, or PDZ7.5BGWX equivalent, key selection criteria include Zener voltage accuracy, thermal resistance (Rth(j-sp) = 50 K/W), non-repetitive surge capability (IZSM = 3.5 A), reverse current (IR ≤ 0.5 μA at VR = 6.0 V), and surface-mount compatibility with standard SOD123 footprint.
Technical Context
This Zener diode operates in reverse breakdown to maintain stable voltage across load variations and temperature shifts. Its 7.5 V nominal working voltage is specified at IZ = 5 mA, with typical temperature coefficient of +4.0 mV/K and low capacitance (170 pF at 1 MHz, VR = 0 V) enabling use in noise-sensitive analog references.
The device supports both steady-state regulation (Ptot = 365 mW on standard FR4 PCB) and transient suppression (PZSM = 40 W for 100 μs pulses), with cathode-anode polarity clearly marked by a bar on the SOD123 body per IEC 60747-2.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 7.28 V to 7.60 V at IZ = 5 mA - ensures tight regulation within ±2 % tolerance band for stable reference design |
| Differential Resistance rdif | ≤ 60 Ω - minimizes output impedance variation under load current changes |
| Reverse Current IR | ≤ 0.5 μA at VR = 6.0 V - guarantees low leakage in high-impedance bias networks |
| Non-repetitive Peak Current IZSM | 3.5 A (tp = 100 μs) - enables transient overvoltage clamping without device failure |
| Thermal Resistance Rth(j-sp) | 50 K/W - allows efficient heat transfer from junction to solder point on 1 cm² cathode pad |
| Forward Voltage VF | ≤ 0.9 V at IF = 10 mA - supports bidirectional protection or dual-function circuit integration |
| Temperature Coefficient SZ | +4.0 mV/K at IZ = 5 mA - provides predictable voltage drift for compensated reference designs |
Pinout & Package
SOD123 plastic surface-mount package (3.75 × 2.55 × 1.3 mm); cathode marked by bar on body; optimized for reflow soldering per IPC-J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to regulated output node; marking bar identifies this terminal; carries reverse current during Zener operation |
| 2 (A) | Anode | Connected to ground or lower-potential rail; completes reverse-biased path for voltage reference or clamp function |

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 | Larger package footprint; higher rdif (80 Ω); not AEC-Q101 qualified | Preferred for cost-sensitive consumer PCBs where automotive qualification is unnecessary |
| MMSZ5235B | 7.5 V nominal, ±5 % tolerance, SOD123 package, Ptot = 500 mW, rdif = 30 Ω | Higher power rating but wider tolerance; no AEC-Q101 certification; different thermal profile | Selected when tighter regulation (lower rdif) is critical and automotive compliance is not required |
Compared with BZX84-C7V5 and MMSZ5235B, PDZ7.5BGWX uniquely combines AEC-Q101 qualification, ±2 % tolerance, and SOD123 form factor-making it the only option for space-constrained automotive modules demanding both precision and reliability.

FAQ
What is the maximum continuous power dissipation for PDZ7.5BGWX on a standard FR4 PCB?
The total power dissipation (Ptot) is 365 mW when mounted on an FR4 PCB with single-sided copper, tin-plated, and standard SOD123 footprint. This rating applies at Tamb ≤ 25 °C; derating is required above that temperature per the thermal resistance curve in the datasheet.
How is polarity identified on the PDZ7.5BGWX SOD123 package?
Polarity is indicated by a marking bar on the device body, which denotes the cathode (pin 1). The anode (pin 2) is the unmarked end. This matches the simplified outline in Table 2 of the Nexperia datasheet and aligns with IEC 60747-2 marking conventions for discrete diodes.
Does PDZ7.5BGWX support reflow soldering, and what profile is recommended?
Yes-reflow soldering is the only recommended method. The device complies with IPC-J-STD-020 moisture sensitivity level 1 and is rated for peak temperatures up to 260 °C. Recommended footprint dimensions (4.18 mm × 1.11 mm pad length/width) are specified in Figure 9 of the datasheet.
What is the reverse current specification at 6.0 V for PDZ7.5BGWX?
The maximum reverse current (IR) is 0.5 μA at VR = 6.0 V and Tj = 25 °C. This low leakage enables use in high-impedance voltage divider networks and battery-powered sensor nodes where standby current must remain below 1 μA.
