Product details
Overview
GDZ10LP3-7 from Diodes Incorporated is a 10 V, ±5% tolerance ultra-small leadless Zener diode in X3-DFN0603-2 package (0.6 × 0.3 mm, 0.3 mm profile), rated for 250 mW power dissipation at +25°C, with reverse leakage ≤0.2 µA at 7.0 V, and qualified to AEC-Q101 for automotive-grade reliability. It serves as a precision voltage reference or overvoltage clamp in space-constrained, low-power battery management circuits.
For engineers reviewing the GDZ10LP3-7 datasheet, GDZ10LP3-7 pinout, GDZ10LP3-7 application, or GDZ10LP3-7 equivalent, key selection criteria include its 10 V nominal Zener voltage with ±5% tolerance, ultra-low 0.2 µA IR at VR = 7.0 V, 250 mW PD rating, AEC-Q101 qualification, and X3-DFN0603-2 footprint compatibility with high-density PCB layouts.
Technical Context
This device operates in reverse breakdown mode to maintain stable voltage regulation across load and line variations. Its low leakage current (≤0.2 µA at 7.0 V) and tight 10.0 V ±5% Zener voltage tolerance (9.5–10.5 V) enable accurate clamping in low-current bias networks and reference dividers.
The X3-DFN0603-2 package features a cathode bar marking, matte tin-plated copper leadframe, and UL 94V-0 molding compound - optimized for automated reflow assembly and thermal performance with RθJA = 500°C/W on FR-4 PCB using recommended pad layout.
Key Specifications

FAQ
What is the maximum reverse voltage (VR) that GDZ10LP3-7 can withstand before breakdown?
GDZ10LP3-7 exhibits controlled Zener breakdown at its nominal 10 V rating, with guaranteed operation up to 9.5 V (min) and 10.5 V (max) at 5 mA test current. Below 7.0 V, reverse leakage remains ≤0.2 µA - meaning it does not conduct significantly until approaching its specified Zener voltage, making it unsuitable as a general-purpose blocking diode below that threshold.
Is GDZ10LP3-7 suitable for use in high-frequency signal paths?
No - GDZ10LP3-7 is not designed for RF or high-speed signal routing. Its total capacitance is not characterized in the datasheet, and its primary function is DC voltage regulation or low-speed transient clamping. For signal-path protection, dedicated low-capacitance TVS diodes such as D3V3M1U2UP-7 should be used instead.
How does the X3-DFN0603-2 package affect solder reflow profile requirements?
The X3-DFN0603-2 package requires standard lead-free reflow per J-STD-020, with peak temperature ≤260°C and time above liquidus (TAL) of 60–90 seconds. Its small mass demands precise thermal profiling to avoid tombstoning; Diodes recommends using their suggested pad layout (0.23 mm × 0.61 mm) and 0.12 mm stencil aperture for optimal wetting and coplanarity.
Does GDZ10LP3-7 support bidirectional transient suppression?
No - GDZ10LP3-7 is a unidirectional Zener diode with cathode-anode polarity. It conducts only in reverse bias (cathode positive relative to anode) and offers no forward surge capability. For bidirectional protection, a back-to-back Zener pair or dedicated bidirectional TVS like SMAJ10A must be implemented externally.
