Product details
Overview
GDZ6V8LP3-7 from Diodes Incorporated is a 6.8 V, 5 mA Zener diode in an ultra-small X3-DFN0603-2 (0.6 × 0.3 mm) leadless package with 250 mW power dissipation, 0.5 µA max reverse leakage at 3.5 V, and AEC-Q101 qualification for automotive reliability. It serves as a precision voltage reference or overvoltage clamp in space-constrained, low-power circuits such as battery management IC biasing and sensor signal conditioning.
For engineers reviewing the GDZ6V8LP3-7 datasheet, GDZ6V8LP3-7 pinout, GDZ6V8LP3-7 application, or GDZ6V8LP3-7 equivalent, key selection criteria include its 6.47–7.14 V zener voltage tolerance at 5 mA, ultra-low profile (0.3 mm), cathode-bar marking, matte tin terminals, and suitability for high-volume automated SMT assembly in automotive and portable electronics.
Technical Context
This Zener diode operates in reverse breakdown to maintain stable voltage regulation across varying load currents. Its thermal resistance of 500 °C/W and derating curve enable reliable operation up to +150 °C ambient when mounted per recommended FR-4 pad layout.
The device exhibits low capacitance (<2 pF typical at 1 MHz) and negligible forward voltage drop (<0.9 V at 10 mA), making it suitable for high-frequency noise suppression and low-current reference applications where minimal loading and fast transient response are required.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|

FAQ
What is the maximum reverse voltage (VR) that GDZ6V8LP3-7 can withstand before breakdown?
The GDZ6V8LP3-7 is specified to maintain ≤0.5 µA reverse leakage at 3.5 V, and its nominal zener voltage is 6.8 V at 5 mA test current. Breakdown occurs gradually starting near 6.47 V (minimum VZ), with full regulation established above 6.8 V. It is not rated for sustained reverse blocking above its zener voltage.
Is GDZ6V8LP3-7 compatible with lead-free reflow soldering profiles?
Yes - GDZ6V8LP3-7 uses matte tin over copper leadframe and is qualified for standard JEDEC J-STD-020 lead-free reflow profiles, including peak temperatures up to 260°C. Its Moisture Sensitivity Level 1 eliminates pre-bake requirements.
How does the X3-DFN0603-2 package affect thermal performance compared to larger Zener packages?
The X3-DFN0603-2 package has a thermal resistance of 500 °C/W (junction-to-ambient), significantly higher than larger packages like SOD-123 (~300 °C/W). This limits continuous power dissipation to 250 mW at +25°C and requires careful PCB copper area design to avoid exceeding 150°C junction temperature.
Can GDZ6V8LP3-7 be used in place of a 6.8 V Zener in a linear regulator feedback network?
Yes - its tight 6.47–7.14 V tolerance at 5 mA and low dynamic impedance support stable feedback reference generation. However, ensure operating current stays within 1–10 mA to maintain regulation accuracy and avoid self-heating-induced drift.
