Product details
Overview
GDZ11LP3-7 from Diodes Incorporated is a 11 V ±5% 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 0.1 µA max reverse leakage at 8.0 V and AEC-Q101 qualified for automotive reliability. It serves as a precision voltage reference or overvoltage clamp in space-constrained, battery-powered sensor nodes.
For engineers reviewing the GDZ11LP3-7 datasheet, GDZ11LP3-7 pinout, GDZ11LP3-7 application, or GDZ11LP3-7 equivalent, key selection criteria include its 11 V nominal Zener voltage with ±4.5% tolerance (10.45–11.55 V), ultra-low leakage (<0.1 µA @ VR = 8.0 V), thermal resistance of 500 °C/W, and suitability for automated SMT assembly on FR-4 PCBs.
Technical Context
This device operates in reverse breakdown mode to maintain stable voltage regulation under controlled current conditions. Its Zener voltage is specified at IZT = 5 mA with typical temperature coefficient near −0.05 %/°C for 11 V grade, and it exhibits low dynamic impedance below 100 Ω in the operating range.
The X3-DFN0603-2 package features matte tin-plated copper leadframe terminals, cathode bar marking, and J-STD-020 Level 1 moisture sensitivity-enabling reflow compatibility without baking. Thermal derating begins above +25°C per Figure 1, reaching zero power at +150°C ambient.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX384-B11,115 | Same 11 V nominal, SOD-323 package (1.7 × 1.3 mm), 300 mW rating, higher leakage (≤100 nA @ 8.0 V) | Larger footprint limits use in ultra-dense layouts; better thermal margin for intermittent surge handling | Select when board space permits and higher pulse power capability is needed over ultra-low leakage |
| MMSZ5240BT1G | 10 V nominal (±5%), SOD-123 package (3.7 × 1.6 mm), 500 mW rating, leakage ≤1 µA @ 7.6 V | Lower voltage grade and larger size; suited for general-purpose clamping where 11 V precision is not required | Choose for cost-sensitive industrial designs where 10 V regulation suffices and manual placement is acceptable |
Compared with BZX384-B11 and MMSZ5240BT1G, GDZ11LP3-7 delivers the smallest footprint and lowest leakage for 11 V regulation, making it optimal for miniaturized, battery-operated systems-whereas alternatives trade size for thermal headroom or cost.

FAQ
What is the maximum reverse voltage (VR) at which GDZ11LP3-7 guarantees ≤0.1 µA leakage?
The datasheet specifies IR ≤ 0.1 µA at VR = 8.0 V for GDZ11LP3-7. This condition is tested per Note 6 using short-duration pulses to avoid self-heating. At VR = 10.45 V (minimum Zener voltage), leakage remains below 1 µA but is not guaranteed at the 0.1 µA level.
Can GDZ11LP3-7 be used in place of GDZ10LP3-7 in a 10 V reference circuit?
No-GDZ11LP3-7 has a nominal Zener voltage of 11 V (range 10.45–11.55 V), while GDZ10LP3-7 is rated at 10 V (9.50–10.50 V). Substituting introduces a systematic 10% voltage error. Circuit redesign or recalibration would be required to accommodate the higher regulation point.
Does the X3-DFN0603-2 package require special stencil or reflow profile considerations?
Yes-the 0.6 × 0.3 mm footprint demands precise stencil aperture design (0.35 mm × 0.20 mm recommended) and controlled reflow ramp rates (≤2°C/s) to prevent tombstoning. J-STD-020 Level 1 moisture sensitivity means no baking is needed, but humidity exposure must remain <60% RH prior to placement.
Is GDZ11LP3-7 suitable for bidirectional ESD protection?
No-it is a unidirectional Zener diode optimized for reverse-bias voltage regulation/clamping only. For bidirectional ESD protection, TVS diodes such as D24M3LPSOT23-4 or SP1003-01UTG are required, as they feature symmetric breakdown in both polarities and specified ESD immunity (e.g., ±30 kV contact).
