Product details
Overview
GDZ22LP3-7 from Diodes Incorporated is a 22 V, ±4.5% tolerance 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 15.4 µA max reverse leakage at 15.4 V, and qualified to AEC-Q101 for automotive reliability. It serves as a precision voltage reference or overvoltage clamp in space-constrained, low-power circuits such as battery management ICs and sensor signal conditioning.
For engineers reviewing the GDZ22LP3-7 datasheet, GDZ22LP3-7 pinout, GDZ22LP3-7 application, or GDZ22LP3-7 equivalent, key selection criteria include its 22 V nominal Zener voltage, 5 mA test current, 0.3 mm profile, cathode-bar marking, and thermal resistance of 500 °C/W - all critical for high-density PCB layout and thermal-aware design in portable and automotive electronics.
Technical Context
This Zener diode operates in reverse breakdown mode with a tightly controlled 20.9–23.1 V Zener voltage range at 5 mA test current. Its low 15.4 µA reverse leakage at VR = 15.4 V enables stable biasing in ultra-low-current applications like coin-cell-powered IoT sensors.
The X3-DFN0603-2 package features matte tin-plated copper leads, J-STD-020 Level 1 moisture sensitivity, and UL 94V-0 flammability rating - supporting reflow-compatible automated assembly while maintaining thermal performance up to +150°C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 22 V nominal, 20.9–23.1 V range at IZT = 5 mA - ensures predictable clamping within ±4.5% across production lots |
| Power Dissipation (PD) | 250 mW at TA = +25°C - defines maximum steady-state power before thermal derating begins |
| Reverse Leakage (IR) | ≤15.4 µA at VR = 15.4 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 load |
| Operating Temperature | −55°C to +150°C - supports under-hood automotive and industrial environments without derating |
| Package | X3-DFN0603-2 (0.6 × 0.3 × 0.3 mm) - fits 0201 footprint constraints while enabling automated pick-and-place |
Pinout & Package

Key Features
| Feature | Design Value |
|---|---|
| Ultra-small footprint | 0.6 × 0.3 mm body size - reduces PCB area by >50% vs. SOD-323, enabling dense sensor module layouts |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX384-B22,115 (Nexperia) | Same 22 V nominal, but SOD-323 package (1.7 × 1.3 mm); 200 mW PD; 100 nA IR @ 17.6 V | Larger footprint limits high-density designs; lower leakage suits ultra-low-power metering | Select when lower leakage outweighs board space constraints and SMT process supports larger package |
| MMSZ5247ET1G (onsemi) | SOD-123 package (3.7 × 1.6 mm); 500 mW PD; 100 nA IR @ 17.6 V; ±5% tolerance | Higher power handling but 12× larger area; not AEC-Q101 qualified | Choose for non-automotive applications requiring higher surge energy absorption and relaxed size requirements |
Compared with BZX384-B22 and MMSZ5247ET1G, GDZ22LP3-7 delivers the smallest footprint and automotive qualification, trading off slightly higher leakage for space and reliability - making it optimal for next-gen compact, safety-critical modules where board real estate and qualification are primary constraints.

FAQ
What is the maximum allowable reverse voltage before breakdown for GDZ22LP3-7?
The GDZ22LP3-7 exhibits sharp Zener breakdown at 20.9–23.1 V when tested at 5 mA. Below 20.9 V, reverse current remains ≤15.4 µA at 15.4 V - confirming stable non-conducting behavior well below nominal Zener voltage. Operation below 15.4 V ensures negligible leakage in bias networks.
Can GDZ22LP3-7 be used in reflow soldering processes?
Yes - GDZ22LP3-7 is qualified for standard Pb-free reflow per J-STD-020, with Level 1 moisture sensitivity and matte tin-plated terminals compatible with SAC305 paste. Its X3-DFN0603-2 package withstands peak temperatures up to 260°C for ≤60 seconds without degradation.
How does the 0.3 mm package height impact thermal performance?
The 0.3 mm profile reduces thermal mass and constrains heat spreading path, resulting in a high RθJA of 500 °C/W. Effective thermal management requires minimum 10 mm² of 1-oz copper connected directly to both terminals, per Diodes' suggested pad layout, to avoid exceeding +150°C junction temperature at full 250 mW load.
Is GDZ22LP3-7 suitable for bidirectional ESD protection?
No - GDZ22LP3-7 is a unidirectional Zener diode optimized for reverse-bias voltage regulation. It lacks symmetric clamping characteristics required for bidirectional ESD protection. For such applications, purpose-built TVS diodes like D24Z3PQ-7 or PUSB3FR4 are recommended instead.
