Product details
Overview
GDZ20LP3-7 from Diodes Incorporated is a 20V ±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 reverse leakage ≤0.1 µA at 14.0 V and thermal resistance of 500 °C/W. It serves as a precision voltage reference or overvoltage clamp in space-constrained portable electronics.
For engineers reviewing the GDZ20LP3-7 datasheet, GDZ20LP3-7 pinout, GDZ20LP3-7 application, or GDZ20LP3-7 equivalent, key selection criteria include its AEC-Q101 qualification, ultra-low profile (0.3 mm), cathode-bar marking, matte tin terminals, and guaranteed 20.0 V nominal Zener voltage at 5 mA test current.
Technical Context
This Zener diode operates in reverse breakdown to maintain stable voltage regulation across varying load currents and temperatures. Its 20 V nominal Zener voltage exhibits a positive temperature coefficient (~0.06 %/°C per Figure 7), and it delivers ≤0.1 µA reverse leakage at VR = 14.0 V - critical for low-power battery monitoring circuits.
The X3-DFN0603-2 package enables high-density PCB layouts and automated placement, with JEDEC Level 1 moisture sensitivity and UL 94V-0 flammability rating. Thermal performance is defined with FR-4 board mounting using Diodes Incorporated's recommended pad layout.
Key Specifications
| Parameter | Value and Actual Design Meaning |

| Power Dissipation (PD) | 250 mW at TA = +25°C - defines maximum continuous steady-state power handling on standard FR-4 |
| Reverse Leakage (IR) | ≤0.1 µA at VR = 14.0 V - minimizes standby current drain in battery-powered systems |
| Thermal Resistance (RθJA) | 500 °C/W - determines junction temperature rise under load; requires thermal-aware PCB layout |
| Operating Temperature | −55°C to +150°C - supports automotive under-hood and industrial control environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX384-B20,115 | Same 20 V nominal Zener, but SOD-323 package (1.7 × 1.3 mm); 300 mW PD; higher leakage (≤1 µA at 14 V) | Larger footprint; less suitable for ultra-dense layouts but offers higher power margin | Select when board space allows and higher surge power handling is needed |
| MMSZ5249BS-7-F | SOD-123 package (3.7 × 1.6 mm); 500 mW PD; tighter 20 V tolerance (±5% same), but leakage ≤0.1 µA only at 16 V | Not AEC-Q101 qualified; lacks automotive reliability validation | Prefer for cost-sensitive industrial designs where automotive qualification is unnecessary |
Compared with BZX384-B20 and MMSZ5249BS-7-F, GDZ20LP3-7 uniquely combines AEC-Q101 qualification, 0.6 × 0.3 mm footprint, and sub-0.1 µA leakage at 14 V - making it optimal for space- and reliability-critical automotive and portable applications.

FAQ
What is the Zener test current (IZT) for GDZ20LP3-7, and why does it matter?
The Zener test current is 5 mA, specified per the Electrical Characteristics table. This current defines the operating point at which the 20.0 V nominal Zener voltage is guaranteed. Designers must ensure the bias network delivers ≥5 mA under worst-case conditions to maintain regulation accuracy and avoid voltage droop below the specified range.
How does the X3-DFN0603-2 package affect solder reflow profile requirements?
The X3-DFN0603-2 package has JEDEC Level 1 moisture sensitivity and requires no bake preconditioning. Its ultra-low mass (0.2 mg) demands precise reflow profiling: peak temperature must not exceed 260°C, with time above 217°C limited to 60–90 seconds to prevent delamination or voiding while ensuring full solder wetting on the matte tin terminals.
Is GDZ20LP3-7 suitable for bidirectional ESD protection?
No - GDZ20LP3-7 is a unidirectional Zener diode optimized for reverse-bias voltage regulation and clamping. It lacks symmetric breakdown characteristics required for bidirectional ESD protection. For such use, purpose-built TVS diodes like D3V3M1U2SOT-7 or SP1003-01UTG are appropriate alternatives.
Does GDZ20LP3-7 have a specified Zener impedance (ZZT) value?
No - the datasheet DS35065 Rev. 19 does not list dynamic impedance (ZZT) for the GDZ20LP3-7. Designers should rely on the specified voltage tolerance (19.0–21.0 V at 5 mA) and leakage data for stability analysis; for low-impedance regulation, consider higher-power Zeners or active references where ZZT is characterized.
