Product details
Overview
DDZ5V6BSF-7 from Diodes Incorporated is a precision 0.5W surface-mount Zener diode with nominal zener voltage 5.6V (min 5.45V, max 5.73V), 20mA test current, 80Ω dynamic impedance at 1kHz, and 7.5µA reverse leakage at 2V. It operates from −65°C to +150°C and is used for voltage regulation and reference in power supply feedback loops, analog sensor biasing, and overvoltage protection circuits.
For engineers reviewing the DDZ5V6BSF-7 datasheet, DDZ5V6BSF-7 pinout, DDZ5V6BSF-7 application, or DDZ5V6BSF-7 equivalent, this page delivers verified package dimensions, thermal derating behavior, zener tolerance tightness, and automotive-grade qualification status - all critical for high-reliability board-level design and BOM validation.
Technical Context
This device functions as a two-terminal voltage reference diode operating in reverse breakdown mode. Its zener voltage is specified at IZT = 20mA with ±1.9% tolerance (5.45–5.73V), and it exhibits low dynamic impedance (80Ω @ 1kHz) to maintain stable regulation under varying load conditions.
Thermal performance is defined by RθJA = 250°C/W on FR-4 PCB (10mm × 10mm pad), with full power dissipation (500mW) rated only at TA ≤ 50°C per the derating curve. The SOD323F package supports automated assembly and complies with AEC-Q101 for automotive applications when qualified through Diodes' PPAP process.
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 |
|---|---|---|---|
| BZX584C5V6 | Same 5.6V nominal, ±5% tolerance (5.32–5.88V), 300mW rating, SOD-523 package | Lower power handling and looser tolerance limit use in non-critical biasing only | Select when footprint space is constrained and regulation accuracy < ±2% is acceptable |
| MMSZ5232BS | 5.6V nominal, ±5% tolerance, 500mW, SOD-123 package, higher RθJA (~350°C/W) | Larger footprint but same power; thermal performance inferior on dense PCBs | Choose if legacy SOD-123 layout compatibility is required and board area permits |
Compared with BZX584C5V6 and MMSZ5232BS, DDZ5V6BSF-7 offers tighter voltage tolerance and superior thermal resistance in a smaller SOD323F package - making it optimal for space-constrained, high-accuracy industrial and automotive voltage reference designs.

FAQ
What is the maximum continuous reverse voltage that can be safely applied to DDZ5V6BSF-7?
The device is rated for operation up to its zener voltage (5.45–5.73V) in reverse breakdown. Applying reverse voltage significantly above 5.73V risks exceeding its 500mW power limit unless current is strictly limited by external series resistance. Absolute maximum reverse voltage is not specified beyond the zener range - design must ensure IZ × VZ ≤ PD derated per ambient temperature.
Does DDZ5V6BSF-7 require a heatsink for 500mW operation?
No heatsink is required. The 500mW rating is specified for mounting on a standard FR-4 PCB with a 10mm × 10mm copper pad (per Note 5). Full power is only permissible below 50°C ambient; above that, linear derating applies per Figure 1 (e.g., ~350mW at 85°C ambient).
Is DDZ5V6BSF-7 qualified for automotive applications?
Yes - Diodes offers AEC-Q101 qualification for this part upon request, including PPAP documentation and manufacturing in IATF 16949-certified facilities. Standard commercial-grade units are not automatically qualified; automotive-grade ordering requires explicit specification and coordination with Diodes' automotive sales team.
How does the SOD323F package compare to SOD-123 in terms of thermal performance?
SOD323F achieves RθJA = 250°C/W on FR-4 (vs. ~350°C/W for typical SOD-123), due to optimized leadframe geometry and thermal pad design. This 29% lower junction-to-ambient resistance allows higher power operation at the same ambient temperature or cooler junction temperatures in thermally dense layouts.
