Product details
Overview
DDZ6V2BSF-7 from Diodes Incorporated is a precision 0.5W surface-mount Zener diode in SOD323F package, with nominal zener voltage 6.2 V (min 5.96 V, max 6.27 V) at 20 mA test current, 50 Ω dynamic impedance, and 7.5 µA reverse leakage at 3 V. It delivers tight voltage tolerance for voltage reference and regulation in low-power analog circuits, including sensor signal conditioning and power supply feedback loops.
For engineers reviewing the DDZ6V2BSF-7 datasheet, DDZ6V2BSF-7 pinout, DDZ6V2BSF-7 application, or DDZ6V2BSF-7 equivalent, this part supports stable voltage clamping and reference generation where ±3% VZ accuracy, low thermal resistance (250 °C/W), and AEC-Q200-compatible manufacturing are required.
Technical Context
This Zener diode operates in reverse breakdown to maintain a stable reference voltage across its cathode–anode terminals. Its 50 Ω zener impedance at 20 mA ensures minimal voltage deviation under load variation, while the 250 °C/W junction-to-ambient thermal resistance enables reliable operation on standard FR-4 PCBs with 10 mm × 10 mm copper pads.
The device features a cathode band marking for polarity identification and uses matte tin–annealed copper alloy leads for robust solderability per MIL-STD-202. It is halogen- and antimony-free, fully RoHS 3 compliant, and qualified for automotive-grade change control per IATF 16949 processes.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX384-B6V2,215 (Nexperia) | Same 6.2 V nominal, but ±5% tolerance (5.89–6.51 V); 80 Ω ZZT; SOD323 package | Higher VZ spread increases calibration burden in precision references | Select if cost sensitivity outweighs voltage accuracy needs and board layout allows SOD323 pinout |
| MMSZ4687T1G (onsemi) | 6.2 V nominal, ±5% tolerance; 60 Ω ZZT; SOD123 package (larger footprint, higher RθJA) | SOD123 requires 30% more PCB area and exhibits 350 °C/W thermal resistance | Choose only when legacy SOD123 footprint is fixed and thermal margin exceeds 40°C |
Compared with BZX384-B6V2,215 and MMSZ4687T1G, DDZ6V2BSF-7 offers tighter voltage control (±2.7% vs. ±5%), lower dynamic impedance (50 Ω vs. 60–80 Ω), and superior thermal performance in the smaller SOD323F package-making it optimal for space- and accuracy-critical designs.

FAQ
What is the maximum continuous power dissipation for DDZ6V2BSF-7 on a standard FR-4 PCB?
The DDZ6V2BSF-7 is rated for 500 mW maximum power dissipation when mounted on an FR-4 PCB with a 10 mm × 10 mm copper pad. Derating begins above +25°C ambient, reaching ~250 mW at +85°C and ~125 mW at +125°C, based on its 250 °C/W thermal resistance.
How does the cathode band marking align with the SOD323F package outline?
The cathode band is located on the top surface of the SOD323F package, aligned with the shorter end of the rectangular body. In top-view orientation, it corresponds to the terminal labeled "K" in Diodes' official package drawing, directly adjacent to the cathode die bond wire location.
Is DDZ6V2BSF-7 qualified for automotive applications under AEC-Q200?
DDZ6V2BSF-7 is manufactured in IATF 16949-certified facilities and supports PPAP documentation. While not individually AEC-Q200 tested, Diodes states that parts in this family meet automotive change control requirements-including material traceability, process validation, and reliability testing protocols aligned with AEC-Q200 stress categories.
Can DDZ6V2BSF-7 replace a 6.2 V Zener in a TL431-based feedback circuit?
Yes-DDZ6V2BSF-7 provides a direct shunt reference alternative to TL431 in low-current feedback paths (<5 mA). Its 5.96–6.27 V range and 50 Ω impedance offer comparable regulation accuracy without requiring external bias resistors or compensation networks.
