Product details
Overview
GDZ4V3LP3-7 from Diodes Incorporated is a surface-mount Zener diode with nominal 4.3 V breakdown voltage (4.08–4.53 V at 5 mA), 250 mW power dissipation, and ultra-small X3-DFN0603-2 package (0.6 × 0.3 × 0.3 mm). It delivers low leakage (<5 µA at 1.0 V reverse) and is AEC-Q101 qualified for automotive-grade reliability in voltage regulation and overvoltage protection circuits.
For engineers reviewing the GDZ4V3LP3-7 datasheet, GDZ4V3LP3-7 pinout, GDZ4V3LP3-7 application, or GDZ4V3LP3-7 equivalent, key selection criteria include its tight Zener voltage tolerance, ultra-low profile for space-constrained PCBs, thermal resistance of 500 °C/W, and suitability for battery-powered systems requiring stable reference or clamping under low-current conditions.
Technical Context
This Zener diode operates in reverse-biased breakdown mode to maintain a stable reference voltage across its terminals. Its 4.3 V nominal Zener voltage is specified at 5 mA test current, with temperature coefficient optimized near zero crossing for minimal drift across -55 °C to +150 °C operating range.
The device uses a planar silicon junction structure with cathode-bar marking on the top surface and matte tin-plated copper leadframe for solderability. Thermal performance is defined for FR-4 PCB mounting with Diodes Incorporated's recommended pad layout, enabling predictable derating per Figure 1.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 4.3 V nominal, 4.08–4.53 V min/max at IZT = 5 mA - defines precise clamping threshold for 3.3 V/5 V rail protection |
| Power Dissipation (PD) | 250 mW at TA = +25 °C - sets maximum continuous power handling on standard FR-4 board |
| Reverse Leakage (IR) | <5 µA at VR = 1.0 V - ensures negligible standby current in battery-critical applications |
| Thermal Resistance (RθJA) | 500 °C/W - determines junction-to-ambient temperature rise per watt, critical for thermal design margin |
| Operating Temperature | -55 °C to +150 °C - supports under-hood automotive and industrial environments without derating loss |
| Package | X3-DFN0603-2 (0.6 × 0.3 × 0.3 mm) - enables high-density placement in wearables, IoT sensors, and portable electronics |
Pinout & Package

FAQ
What is the maximum reverse voltage this diode can withstand before breakdown?
The GDZ4V3LP3-7 has a nominal Zener voltage of 4.3 V, with guaranteed breakdown between 4.08 V and 4.53 V at 5 mA test current. Below 1.0 V reverse bias, leakage remains under 5 µA. It is not rated for sustained operation above its specified Zener range - exceeding 4.53 V risks thermal runaway unless current is strictly limited by external series resistance.
Is GDZ4V3LP3-7 compatible with lead-free reflow profiles?
Yes - GDZ4V3LP3-7 is fully RoHS-compliant and qualified for standard lead-free reflow profiles (J-STD-020, peak temperature up to 260 °C). Its matte tin-plated copper leadframe meets MIL-STD-202 Method 208 solderability requirements, and moisture sensitivity level is rated at Level 1, eliminating pre-bake requirements.
How does temperature affect its Zener voltage stability?
Per Figure 7 in DS35065 Rev. 19, GDZ4V3LP3-7 exhibits a temperature coefficient near zero (±0.02 %/°C typical) due to its 4.3 V rating falling close to the crossover point between positive and negative TC regions. This yields minimal drift - approximately ±0.03 V over -40 °C to +85 °C ambient - making it suitable for stable reference use without compensation.
Can this diode replace larger-package Zeners like DO-35 or SOD-123 in existing designs?
Yes, but only if PCB layout accommodates the X3-DFN0603-2 footprint (0.6 × 0.3 mm) and thermal constraints are verified. While electrical characteristics match standard 4.3 V Zeners, its 250 mW rating and 500 °C/W RθJA require careful thermal pad design per Diodes' suggested layout. No pin-to-pin compatibility exists with leaded or larger SMD packages.
