Product details
Overview
GDZ9V1LP3Q-7 from Diodes Incorporated is a 9.1 V, ±5% tolerance Zener diode in an ultra-small X3-DFN0603-2 package (0.6 × 0.3 mm, 0.3 mm height), rated for 250 mW power dissipation at +25°C, with 0.5 µA max reverse leakage at 6.0 V and AEC-Q101 qualified for automotive use.
For engineers reviewing the GDZ9V1LP3Q-7 datasheet, GDZ9V1LP3Q-7 pinout, GDZ9V1LP3Q-7 application, or GDZ9V1LP3Q-7 equivalent, this part supports precision voltage reference, overvoltage protection, and low-power biasing in space-constrained automotive ECUs, battery management systems, and portable sensor interfaces where thermal efficiency and RoHS/Green compliance are critical.
Technical Context
This Zener diode operates in reverse breakdown to maintain stable voltage regulation across varying load currents. Its 5 mA test current (IZT) and tight 8.65–9.56 V Zener voltage range ensure predictable clamping behavior under defined bias conditions.
Thermal resistance of 500°C/W (junction-to-ambient, FR-4 PCB) and derating curve support operation up to +150°C junction temperature. The cathode-bar marked top-side orientation and matte tin-plated copper leadframe enable reliable automated reflow assembly and solderability per MIL-STD-202.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX384-B9V1,115 (Nexperia) | Same 9.1 V nominal, SOD-323 package (1.7 × 1.3 mm), 300 mW rating, 0.5 µA IR @ 6 V | Larger footprint; higher power but less space-efficient | Select if board layout allows larger package and higher surge margin is prioritized over miniaturization |
| MMSZ4687T1G (onsemi) | 9.1 V nominal, SOD-123 package (2.7 × 1.4 mm), 500 mW rating, 1.0 µA IR @ 6 V | Higher leakage, larger size, higher power - suited for non-battery-critical industrial use | Choose when thermal headroom is needed and leakage sensitivity is secondary to cost or availability |
Compared with BZX384-B9V1 and MMSZ4687T1G, GDZ9V1LP3Q-7 delivers superior space efficiency and lowest leakage in its class, making it optimal for automotive and portable designs where PCB area and standby current are tightly constrained.

FAQ
What is the maximum reverse voltage (VR) at which leakage current is specified for GDZ9V1LP3Q-7?
The datasheet specifies 0.5 µA maximum reverse leakage current (IR) at VR = 6.0 V. This value is measured under steady-state DC conditions at +25°C ambient and reflects the diode's ability to hold off sub-breakdown voltages with negligible current draw-critical for battery longevity in always-on systems.
Is GDZ9V1LP3Q-7 suitable for reflow soldering using standard lead-free profiles?
Yes. The device uses matte tin over copper leadframe and is qualified per J-STD-020 Moisture Sensitivity Level 1, allowing unlimited floor life and compatibility with IPC/JEDEC J-STD-020 Class 3 lead-free reflow profiles (peak 260°C). No pre-bake is required prior to assembly.
How does the X3-DFN0603-2 package affect thermal performance compared to larger Zener packages?
The X3-DFN0603-2's small pad area limits heat spreading, resulting in a higher RθJA of 500°C/W versus ~300°C/W for SOD-123 devices. Designers must follow Diodes' recommended pad layout (0.38 mm C, 0.23 mm X) to achieve rated 250 mW dissipation and avoid localized overheating.
Does GDZ9V1LP3Q-7 require external current-limiting resistors in typical shunt regulator configurations?
Yes. As a two-terminal Zener, it requires a series current-limiting resistor to set operating current within the 5 mA IZT window and prevent thermal runaway. For 12 V input and 9.1 V output, a 560 Ω ±1% resistor delivers ~5.2 mA, ensuring stable regulation while staying within 250 mW PD limits at +25°C.
