Product details
Overview
DZ9F8V2S92-7 from Diodes Incorporated is a surface-mount Zener diode with nominal zener voltage 8.2 V, ±5% tolerance (7.79–8.61 V), 5 mA test current, 30 Ω maximum zener impedance at 5 mA, and 0.5 mA knee current. It operates in ultra-small SOD923 package (1.0 × 0.6 × 0.37 mm), rated for 200 mW power dissipation and −65 °C to +150 °C junction temperature, and is used for precision voltage regulation in space-constrained power rails.
For engineers reviewing the DZ9F8V2S92-7 datasheet, DZ9F8V2S92-7 pinout, DZ9F8V2S92-7 application, or DZ9F8V2S92-7 equivalent, key selection criteria include zener voltage stability at low current, thermal resistance (625 °C/W), cathode-band polarity marking, SOD923 footprint compatibility, and compliance with RoHS, halogen-free, and antimony-free "Green" requirements.
Technical Context
This Zener diode functions as a two-terminal voltage reference device operating in reverse breakdown mode. Its 8.2 V nominal zener voltage exhibits a positive temperature coefficient of +3.2 to +6.2 mV/°C at 5 mA, enabling predictable drift compensation in bias networks. The device uses an alloy-42 leadframe with matte tin annealed terminals for reliable solderability per MIL-STD-202.
The SOD923 package features exposed terminals visible without X-ray inspection, flat leads for thermal efficiency, and UL 94V-0 molded plastic housing. With 0.001 g mass and moisture sensitivity level 1 (per J-STD-020), it supports high-density reflow assembly on FR-4 PCBs using Diodes Incorporated's recommended pad layout.
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-B8V2,215 | Same 8.2 V nominal, but SOD-323 package (1.7 × 1.3 mm); 400 mW PD; 40 Ω ZZT | Larger footprint and higher power rating suit less space-constrained boards with higher thermal margin | Select when board layout allows larger package and higher power headroom is needed |
| MMSZ4687T1G | 8.2 V nominal, SOD-123 package (3.7 × 1.6 mm); 500 mW PD; 30 Ω ZZT; −65 °C to +150 °C | Higher power handling and legacy footprint compatibility, but 3.7× larger area than SOD923 | Choose for drop-in replacement in existing SOD-123 designs requiring identical electrical behavior |
Compared with BZX384-B8V2,215 and MMSZ4687T1G, DZ9F8V2S92-7 delivers identical zener voltage and impedance while occupying the smallest PCB area-critical for modern wearables, IoT nodes, and multi-rail PMICs where board real estate is constrained.

FAQ
What is the cathode identification method for DZ9F8V2S92-7?
The cathode is identified by a visible band printed on the top surface of the SOD923 package. This marking aligns with industry-standard polarity convention and is confirmed in Diodes Incorporated's DS37439 Rev. 5 document, Figure "Marking Information". No additional orientation indicators are present.
Can DZ9F8V2S92-7 be used in reflow soldering processes?
Yes, DZ9F8V2S92-7 is qualified for lead-free reflow soldering per J-STD-020 Level 1 moisture sensitivity. Its matte tin–annealed terminals meet MIL-STD-202 Method 208 solderability requirements, and the SOD923 package supports standard Pb-free peak temperatures up to 260 °C.
What is the minimum recommended pad layout for this device?
Diodes Incorporated specifies a recommended SOD923 pad layout in its package outline documentation (accessible via diodes.com/package-outlines.html). The layout includes defined solder mask openings, copper land dimensions, and thermal relief patterns optimized for 0.2 mm lead width and 625 °C/W thermal performance on FR-4.
How does the temperature coefficient affect regulation accuracy over −40 °C to +85 °C?
With a specified +3.2 to +6.2 mV/°C temperature coefficient at 5 mA, DZ9F8V2S92-7 exhibits a total zener voltage shift of approximately +125 to +235 mV across a 125 °C range. This corresponds to ±1.5% to ±2.9% deviation from nominal 8.2 V, which must be accounted for in precision reference designs.
