Product details
Overview
D3Z5V6BF-7 from Diodes Incorporated is a precision 5.6 V Zener diode in SOD323F package, rated for 400 mW power dissipation on FR-4 PCB, with ±2.2% zener voltage tolerance (5.48–5.73 V at 5 mA), 50 Ω dynamic impedance at 5 mA, and 1 μA maximum reverse leakage at 2.5 V. It serves as a stable voltage reference in low-power analog signal conditioning circuits.
For engineers reviewing the D3Z5V6BF-7 datasheet, D3Z5V6BF-7 pinout, D3Z5V6BF-7 application, or D3Z5V6BF-7 equivalent, key selection criteria include tight VZ tolerance, low ZZT, temperature coefficient of +1.7 mV/°C, and SOD323F footprint compatibility with high-density PCB layouts.
Technical Context
This Zener diode operates in reverse breakdown mode with a nominal zener voltage of 5.6 V at IZT = 5 mA, exhibiting a positive temperature coefficient (+1.7 mV/°C) to offset negative TC components in mixed-signal references. Its 50 Ω zener impedance ensures minimal output voltage variation under load current shifts.
The device is optimized for surface-mount automated assembly, features matte tin annealed terminals solderable per MIL-STD-202 Method 208, and meets AEC-Q200 stress testing requirements when qualified per Diodes' automotive change control program.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX384-B5V6,115 (Nexperia) | Same 5.6 V nominal, ±5% tolerance (vs. ±2.2%), 80 Ω ZZT, SOD323 package | Higher impedance increases output ripple; wider tolerance requires system-level calibration | Select when cost sensitivity outweighs precision requirement and board space allows same footprint |
| MMSZ5232BS-7-F (Diodes Inc.) | Same 5.6 V nominal, ±5% tolerance, 150 Ω ZZT, SOD-123 package (larger) | SOD-123 footprint incompatible with SOD323F layout; higher ZZT degrades load regulation | Choose only if existing design uses SOD-123 and cannot accommodate smaller SOD323F rework |
Compared with BZX384-B5V6 and MMSZ5232BS, D3Z5V6BF-7 delivers tighter voltage tolerance, lower dynamic impedance, and superior thermal performance in the smallest standardized Zener footprint-making it optimal for space-constrained, high-accuracy reference designs where long-term stability matters.

FAQ
What is the maximum allowable reverse current before breakdown onset for D3Z5V6BF-7?
The device exhibits sharp Zener knee behavior starting at approximately 100 µA reverse current, with nominal 5.6 V regulation established at 5 mA test current. Below 100 µA, voltage drops nonlinearly below 5.4 V; operation in this sub-knee region is not specified for regulation accuracy and should be avoided in reference applications.
Can D3Z5V6BF-7 be used in series with another Zener to achieve higher reference voltages?
Yes, but with caution: series connection introduces cumulative tolerance (±4.4% for two units), increased dynamic impedance (100 Ω), and mismatched temperature coefficients that may degrade overall stability. For >5.6 V references, Diodes recommends using dedicated multi-Zener arrays or bandgap-based solutions instead.
Is the SOD323F package compatible with lead-free reflow profiles per J-STD-020?
Yes-the SOD323F package is rated for moisture sensitivity level 1 and supports peak reflow temperatures up to 260°C for ≤60 seconds. Its matte tin annealed terminals meet J-STD-006B solderability requirements and withstand three standard lead-free reflow cycles without degradation.
Does D3Z5V6BF-7 meet AEC-Q200 qualification for automotive use?
The base D3Z5V6BF-7 part is not AEC-Q200 qualified by default; however, Diodes offers automotive-grade variants (e.g., D3Z5V6BFQ-7) with PPAP documentation, IATF 16949 manufacturing, and extended temperature screening. Standard parts require customer qualification for automotive deployment.
