Product details
Overview
GDZ3V3LP3-7 from Diodes Incorporated is a 3.3 V, ±5% tolerance 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 10 µA max reverse leakage at 1.0 V and AEC-Q101 qualified for automotive reliability. It serves as a precision voltage reference or overvoltage clamp in space-constrained, low-power sensor interfaces.
For engineers reviewing the GDZ3V3LP3-7 datasheet, GDZ3V3LP3-7 pinout, GDZ3V3LP3-7 application, or GDZ3V3LP3-7 equivalent, key selection criteria include its 3.3 V nominal Zener voltage, 5 mA test current, 0.3 mm profile, cathode-bar marking, and suitability for battery-powered wearables and automotive body electronics requiring high thermal stability and RoHS/Green compliance.
Technical Context
This Zener diode operates in reverse breakdown to maintain stable voltage regulation across load and line variations. Its low 10 µA max IR at VR = 1.0 V enables minimal standby current draw in always-on circuits, while the 500 °C/W junction-to-ambient thermal resistance reflects performance on standard FR-4 PCBs with recommended pad layout.
The device exhibits a negative temperature coefficient near 3.3 V (≈ –0.05 %/°C per Figure 7), making it suitable for moderate-precision biasing where drift compensation is managed externally. Its 0.2 mg mass and halogen/antimony-free molding compound support lightweight, environmentally compliant portable designs.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX384-B3V3,115 (Nexperia) | Same 3.3 V nominal, but SOD-323 package (1.7 × 1.3 mm); 200 mW rating; 90 nA leakage at 1 V | Larger footprint limits high-density layouts; lower leakage benefits ultra-low-power RTC backup | Select when lowest possible IR outweighs size constraints and SMT reflow compatibility is verified |
| MMSZ3V3T1G (ON Semiconductor) | SOD-123 package (2.7 × 1.4 mm); 500 mW rating; 5 µA leakage at 1 V; ±5% tolerance | Higher power handling suits higher-current clamping; larger size eases manual rework but increases parasitic inductance | Prefer for prototyping or cost-sensitive industrial controls where board space is less constrained |
Compared with BZX384-B3V3 and MMSZ3V3T1G, GDZ3V3LP3-7 delivers the smallest footprint and automotive qualification, trading slightly higher leakage for superior space efficiency and AEC-Q101 compliance-critical for next-gen compact automotive and medical edge nodes.

FAQ
What is the maximum reverse voltage this Zener can withstand before breakdown?
The GDZ3V3LP3-7 has a nominal Zener voltage of 3.3 V with a guaranteed range of 3.14 V to 3.47 V at 5 mA test current. Breakdown occurs within this band; operation above 3.47 V risks exceeding power limits unless current is strictly limited by external series resistance. Absolute maximum reverse voltage is not specified beyond the Zener range.
Is GDZ3V3LP3-7 suitable for use in high-frequency signal paths?
No-it is not optimized for high-frequency applications. Its typical capacitance is ~1.5 pF at 1 MHz (inferred from GDZ5V1LP3 curve in Figure 6), but no frequency response or impedance data is provided. Use only for DC/low-frequency voltage reference or transient clamping, not RF bypass or AC signal conditioning.
How does the thermal derating curve affect practical power handling?
Per Figure 1, power dissipation must be linearly reduced from 250 mW at +25°C to zero at +150°C. At +85°C ambient, allowable power drops to ~175 mW. Designers must calculate worst-case junction temperature using RθJA = 500 °C/W and ensure TJ stays ≤ +150°C under full load.
Can GDZ3V3LP3-7 replace GDZ3V3LP3 without modification?
Yes-the "-7" suffix denotes tape-and-reel packaging (10,000 units per reel); electrically and mechanically identical to GDZ3V3LP3. The base part number refers to the same die and package; only packaging differs. No layout or schematic changes are needed when switching between GDZ3V3LP3 and GDZ3V3LP3-7.
