Product details
Overview
GDZ4V7LP3-7 from Diodes Incorporated is a 4.7 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 reverse leakage ≤2.0 µA at 1.0 V and thermal resistance of 500°C/W. It serves as a precision voltage reference or overvoltage clamp in space-constrained, low-power portable electronics.
For engineers reviewing the GDZ4V7LP3-7 datasheet, GDZ4V7LP3-7 pinout, GDZ4V7LP3-7 application, or GDZ4V7LP3-7 equivalent, key selection criteria include its 4.42–4.90 V zener voltage range at 5 mA test current, ultra-low profile (0.3 mm), AEC-Q101 qualification, RoHS/"Green" compliance, and cathode-bar-marked DFN termination.
Technical Context
This Zener diode operates in reverse breakdown to maintain stable voltage regulation under varying load or supply conditions. Its low leakage (≤2.0 µA @ VR = 1.0 V) and tight tolerance (±5%) support battery-powered systems requiring long shelf life and accurate threshold detection.
The X3-DFN0603-2 package enables high-density PCB layouts and automated reflow assembly. Thermal performance is defined per JEDEC J-STD-020 Level 1 moisture sensitivity and FR-4 pad layout derating - power drops linearly to zero at +150°C ambient.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX384-B4V7,115 (Nexperia) | Same 4.7 V nominal, ±5% tolerance, but in SOD-323 (1.7 × 1.3 mm) - 5.7× larger footprint | Not suitable for ultra-dense layouts; higher RθJA (625°C/W) limits power handling in confined areas | Select when legacy SOD-323 footprint compatibility is required and board space is not constrained |
| MMSZ4704T1G (onsemi) | 4.7 V, ±5%, but in SOD-123 (3.7 × 1.6 mm); 20× larger area and 0.9 mm height - incompatible with thin assemblies | Lacks AEC-Q101 qualification; rated only for commercial temperature range (−65°C to +150°C) | Choose only for cost-sensitive consumer applications where automotive qualification and miniaturization are unnecessary |

FAQ
What is the maximum reverse voltage (VR) at which leakage remains ≤2.0 µA?
The GDZ4V7LP3-7 guarantees reverse leakage ≤2.0 µA at VR = 1.0 V, as specified in the Electrical Characteristics table. At higher reverse voltages below VZ, leakage increases exponentially - e.g., ~10 µA at 3.0 V and ~50 µA at 4.0 V - per Figure 5's reverse characteristics curve.
Can GDZ4V7LP3-7 be used in place of GDZ4V7LP3 without the "-7" suffix?
No. The "-7" suffix denotes tape-and-reel packaging (10,000 units per reel) and is part of the orderable part number. GDZ4V7LP3 (without -7) is not a valid order code per Diodes' documentation - only GDZ4V7LP3-7 is manufactured and distributed.
Is the X3-DFN0603-2 package compatible with standard 0201 pick-and-place equipment?
Yes. The X3-DFN0603-2 package has 0.355 mm pitch and 0.24 mm lead width, matching industry-standard 0201 (0603 metric) feeder and nozzle specifications. Diodes confirms compatibility with Fuji NXT and Yamaha YSM20 pick-and-place platforms per their Suggested Pad Layout guide.
Does GDZ4V7LP3-7 exhibit significant voltage drift over temperature?
Its temperature coefficient is approximately +0.03%/°C near 4.7 V (per Figure 7), resulting in ~±14 mV drift over −40°C to +85°C. This is negligible for most clamping and reference uses, though precision references may require compensation or higher-VZ devices with flatter TC curves.
