Product details
Overview
GDZ6V8LP3Q-7 from Diodes Incorporated is an ultra-small leadless surface-mount Zener diode with a nominal zener voltage of 6.8 V (min 6.47 V, max 7.14 V at 5 mA), 250 mW power dissipation at +25°C, 500°C/W thermal resistance, and AEC-Q101 qualification for automotive use. It features a cathode-bar-marked X3-DFN0603-2 package (0.6 × 0.3 mm, 0.3 mm profile) and is optimized for low-leakage, battery-powered voltage regulation in space-constrained ECUs.
For engineers reviewing the GDZ6V8LP3Q-7 datasheet, GDZ6V8LP3Q-7 pinout, GDZ6V8LP3Q-7 application, or GDZ6V8LP3Q-7 equivalent, this part supports precision voltage reference, overvoltage clamping, and bias stabilization in automotive body control modules, sensor signal conditioning circuits, and low-power microcontroller reset supervision where ultra-miniature footprint and AEC-Q101 reliability are mandatory.
Technical Context
This Zener diode operates in reverse breakdown to maintain stable voltage across its terminals under defined current conditions. Its 6.8 V nominal zener voltage is specified at 5 mA test current (IZT), with reverse leakage current limited to 0.5 µA at 3.5 V VR and maximum 1.0 µA at 3.0 V VR for adjacent variants - confirming tight regulation tolerance and low standby loss.
The X3-DFN0603-2 package uses matte tin-plated copper leadframe, UL 94V-0 molded plastic, and meets J-STD-020 moisture sensitivity Level 1. Thermal derating begins above +25°C per Figure 1, reaching zero power dissipation at +150°C ambient, supporting operation in under-hood automotive environments.

FAQ
What is the maximum reverse voltage (VR) at which GDZ6V8LP3Q-7 guarantees ≤0.5 µA leakage?
GDZ6V8LP3Q-7 guarantees reverse leakage current ≤0.5 µA at VR = 3.5 V, as specified in the Electrical Characteristics table. This value is measured at TA = +25°C and defines the upper limit of safe non-breakdown operation before entering zener conduction.
Can GDZ6V8LP3Q-7 be used in place of GDZ6V2LP3Q-7 in a design?
GDZ6V8LP3Q-7 and GDZ6V2LP3Q-7 share identical package, thermal specs, and qualification status, but differ in zener voltage (6.8 V vs. 6.2 V) and leakage (0.5 µA vs. 1.0 µA at respective VR). Substitution requires verification that the 0.6 V higher clamping threshold meets system voltage margin and regulation requirements.
Is the X3-DFN0603-2 package compatible with standard reflow profiles for lead-free soldering?
Yes - GDZ6V8LP3Q-7's matte tin-plated copper leadframe is qualified per MIL-STD-202, Method 208 and supports JEDEC J-STD-020 Class 1 reflow profiles. Its moisture sensitivity level is rated at Level 1, eliminating bake requirements prior to assembly.
Does GDZ6V8LP3Q-7 require external series resistance in typical voltage reference applications?
Yes - a current-limiting resistor must be placed in series to ensure operating current stays within the 5 mA IZT test condition and below the 250 mW power limit. For example, with a 12 V supply and 6.8 V output, a minimum 1.04 kΩ resistor limits power to 250 mW at +25°C ambient.
