Product details
Overview
DZ9F2V7S92-7 from Diodes Incorporated is a surface-mount Zener diode with nominal zener voltage 2.7 V, ±4.4% tolerance (2.57–2.84 V), 100 Ω maximum zener impedance at 5 mA test current, and 200 mW power dissipation in SOD923 package. It operates from −65 °C to +150 °C and serves as precision voltage reference or overvoltage clamp in space-constrained power management circuits.
For engineers reviewing the DZ9F2V7S92-7 datasheet, DZ9F2V7S92-7 pinout, DZ9F2V7S92-7 application, or DZ9F2V7S92-7 equivalent, key selection criteria include zener voltage accuracy at low current (IZT = 5 mA), thermal resistance (625 °C/W), ultra-small footprint (1.0 × 0.6 mm), reverse leakage (20 µA @ 1 V), and RoHS-compliant matte tin finish on alloy 42 leadframe.
Technical Context
This device functions as a two-terminal, cathode-banded voltage regulation element operating in reverse breakdown. Its zener voltage exhibits a negative temperature coefficient of −3.5 mV/°C, enabling predictable drift compensation in low-voltage bias networks. The SOD923 package uses exposed terminals for direct visual solder joint inspection-eliminating need for X-ray verification.
Thermal performance is defined under JEDEC-standard FR-4 mounting with minimum pad layout: 200 mW derates linearly at 2.0 mW/°C above +25 °C ambient, yielding full-rated dissipation only up to +125 °C case temperature. Junction-to-ambient thermal resistance is fixed at 625 °C/W under those conditions.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX384-B2V7,115 (Nexperia) | Same 2.7 V nominal, but SOD-323 package (1.7 × 1.3 mm); 150 mW PD; 110 Ω ZZT | Larger footprint increases board area; higher thermal resistance (800 °C/W) limits power handling in confined layouts | Select when legacy SOD-323 land patterns exist and thermal margin exceeds 50 mW |
| MMSZ4678T1G (onsemi) | 2.7 V nominal, SOD-123 package (3.7 × 1.6 mm); 500 mW PD; 100 Ω ZZT; +2.5 mV/°C TC | Positive TC causes voltage rise with temperature-unsuitable for precision bias where drift must be minimized | Prefer only in non-critical clamping roles where thermal stability is secondary to power handling |
Compared with BZX384-B2V7 and MMSZ4678T1G, DZ9F2V7S92-7 uniquely combines ultra-compact SOD923 size, negative TC for drift compensation, and verified 200 mW capability-making it optimal for next-gen miniaturized sensor and wearables designs where board space and thermal behavior are co-constrained.

FAQ
What is the maximum reverse voltage before breakdown for DZ9F2V7S92-7?
The rated zener voltage is 2.7 V with a tolerance window of 2.57 V to 2.84 V at 5 mA test current. Breakdown occurs within this range under specified test conditions; operation below 2.57 V maintains high impedance (>1 MΩ), while exceeding 2.84 V risks exceeding the 200 mW power limit unless current is strictly limited.
Can DZ9F2V7S92-7 be used in place of a standard 1N4728A?
No-DZ9F2V7S92-7 is not a drop-in replacement for 1N4728A. The latter is a through-hole 3 W device in DO-41 package with 3.3 V rating and vastly different thermal and electrical characteristics. DZ9F2V7S92-7 is a 200 mW, 2.7 V SOD923 device intended for surface-mount, low-power applications only.
Is the SOD923 package compatible with standard reflow profiles?
Yes-the SOD923 package is qualified for IPC/JEDEC J-STD-020 Level 1 moisture sensitivity and supports standard lead-free reflow profiles (peak 260 °C, 60-second duration). Its alloy 42 leadframe with matte tin finish ensures reliable wetting and void-free solder joints on ENIG and OSP PCB finishes.
Does DZ9F2V7S92-7 require derating at elevated ambient temperatures?
Yes-power dissipation must be linearly derated above +25 °C ambient at 2.0 mW/°C, per the datasheet's derating curve. At +85 °C ambient, maximum allowable power drops to 80 mW (200 mW − 60 °C × 2.0 mW/°C), requiring careful current limiting in thermally constrained layouts.
