Product details
Overview
GDZ9V1LP3-7 from Diodes Incorporated is a 9.1 V ±5% Zener diode in an ultra-small X3-DFN0603-2 (0.6 × 0.3 mm) leadless package, 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-grade reliability. It serves as a precision voltage reference or overvoltage clamp in space-constrained, low-power circuits such as battery management IC monitoring paths.
For engineers reviewing the GDZ9V1LP3-7 datasheet, GDZ9V1LP3-7 pinout, GDZ9V1LP3-7 application, or GDZ9V1LP3-7 equivalent, this page delivers verified mechanical dimensions, thermal derating behavior, reverse leakage vs. temperature, Zener voltage tolerance, and AEC-Q101 qualification status - all critical for high-reliability portable and automotive electronics design.
Technical Context
This device operates as a two-terminal silicon Zener diode with sharp reverse breakdown at nominal 9.1 V under 5 mA test current (IZT), exhibiting a positive temperature coefficient (~0.04 %/°C per Figure 7) typical of mid-voltage Zeners. Its ultra-low profile (0.3 mm height) and DFN packaging enable direct integration into dense PCB layouts without solder joint stress concerns.
The X3-DFN0603-2 package uses matte tin-plated copper leadframe terminals, supports J-STD-020 Level 1 moisture sensitivity, and achieves 500 °C/W junction-to-ambient thermal resistance on standard FR-4 with recommended pad layout. Reverse leakage remains ≤0.5 µA up to 6.0 V, enabling stable biasing in low-current sensing nodes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 9.1 V nominal, 8.65–9.56 V range at IZT = 5 mA - ensures ±5% regulation tolerance in feedback or reference paths |
| Power Dissipation (PD) | 250 mW at TA = +25°C - defines maximum continuous DC power handling before thermal derating applies |
| Reverse Leakage (IR) | ≤0.5 µA at VR = 6.0 V - enables use in microamp-level standby circuits without compromising battery life |
| Thermal Resistance (RθJA) | 500 °C/W - requires careful PCB copper area planning to maintain TJ < 150°C under sustained load |
| Operating Temperature | −55°C to +150°C - supports under-hood automotive and industrial edge-node deployments |
| AEC-Q101 Qualified | Yes - validated for high-reliability automotive applications including engine control and ADAS sensor interfaces |
| Package | X3-DFN0603-2 (0.6 × 0.3 × 0.3 mm) - compatible with 0201 pick-and-place equipment and reflow profiles |
Pinout & Package
The GDZ9V1LP3-7 uses the X3-DFN0603-2 surface-mount package: a 2-terminal, leadless, rectangular DFN with cathode marked by a bar on the top surface. Terminals are matte tin-plated copper; Pin 1 is cathode, Pin 2 is anode.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Cathode Bar) | Zener cathode connection | Connected to higher-potential node in reverse-bias configuration; marking enables automated optical inspection alignment |
| Pin 2 (Anode) | Zener anode connection | Typically tied to ground or low-impedance return path; forms complete clamping loop with cathode |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-small footprint | 0.6 × 0.3 mm body size - saves >60% board area versus SOD-323, enabling miniaturized wearables and TWS earbud PCBs |
| AEC-Q101 qualification | Stress-tested per automotive reliability standards - eliminates need for additional qualification in Tier-1 supply chains |
| Low leakage current | ≤0.5 µA at 6.0 V reverse bias - preserves battery runtime in always-on voltage monitor circuits |
| Lead-free & green construction | Halogen- and antimony-free, RoHS 3 compliant - meets EU ELV and China RoHS requirements for automotive exports |
| Low profile (0.3 mm) | Enables stacking under shields or beneath connectors - critical for ultra-thin mobile and medical patch devices |

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 PD, 0.5 µA IR @ 6 V | Larger footprint limits use in ultra-dense layouts; higher RθJA (650 °C/W) reduces thermal headroom | Select when legacy SMT lines lack 0201-capable placement or reflow profiling for DFNs |
| MMSZ5240B-TP (Micro Commercial Components) | 9.1 V nominal, SOD-123 package (3.7 × 1.6 mm), 500 mW PD, 1.0 µA IR @ 6 V | Higher leakage and larger size preclude use in micro-power or space-critical designs | Prefer where higher power margin is needed and board area is unconstrained, e.g., industrial power supplies |
Compared with BZX384-B9V1 and MMSZ5240B-TP, GDZ9V1LP3-7 offers the smallest footprint and lowest leakage among AEC-Q101-qualified 9.1 V Zeners, making it optimal for next-gen automotive sensors and compact battery-powered systems where board area and quiescent current are primary constraints.

FAQ
What is the maximum allowable Zener test current (IZT) for GDZ9V1LP3-7?
The datasheet specifies IZT = 5 mA as the standardized test condition for measuring nominal Zener voltage. Operating continuously at this current requires strict thermal management due to the 250 mW power limit and 500 °C/W thermal resistance. For long-term reliability, design should limit average IZT to ≤3 mA unless board-level copper area exceeds Diodes' recommended pad layout.
Does GDZ9V1LP3-7 support reflow soldering per JEDEC J-STD-020?
Yes - the X3-DFN0603-2 package is rated for Moisture Sensitivity Level 1, meaning it may be stored indefinitely at ≤30°C/85% RH and subjected to standard Pb-free reflow profiles (peak 260°C, 20–40 sec above 217°C) without baking. The matte tin finish ensures reliable wetting and void-free joints on ENIG and OSP finishes.
How does temperature affect the Zener voltage of GDZ9V1LP3-7?
Per Figure 7 in DS35065 Rev. 19, GDZ9V1LP3-7 exhibits a positive temperature coefficient of approximately +0.04 %/°C near 9.1 V. This means VZ increases by ~3.6 mV/°C over its operating range; for example, at +125°C ambient, VZ rises ~3.6 V from 25°C baseline - a critical factor in precision reference designs requiring temperature compensation.
Can GDZ9V1LP3-7 replace GDZ9V1LP3 in existing designs?
Yes - the "-7" suffix denotes tape-and-reel packaging (10,000 units/reel); electrically and mechanically, GDZ9V1LP3-7 is identical to GDZ9V1LP3. No layout or schematic changes are required. The only difference is packaging format, making it drop-in compatible for automated assembly lines using standard 8 mm carrier tape feeders.
