Product details
Overview
DDZ5V6CSF-7 from Diodes Incorporated is a precision 0.5W surface-mount Zener diode with nominal zener voltage 5.61–5.91 V at 20 mA test current, 80 Ω maximum zener impedance at 1 kHz, and 7.5 µA maximum reverse leakage at 2 V. It operates across –65 °C to +150 °C and is used for voltage regulation and reference in low-power analog circuits, power supply feedback loops, and overvoltage protection.
For engineers reviewing the DDZ5V6CSF-7 datasheet, DDZ5V6CSF-7 pinout, DDZ5V6CSF-7 application, or DDZ5V6CSF-7 equivalent, key selection criteria include tight zener voltage tolerance (±2.7% typical), low thermal resistance (250 °C/W on FR-4), SOD323F package compatibility with automated assembly, and AEC-Q200 readiness for automotive-grade designs.
Technical Context
This Zener diode functions as a two-terminal voltage reference device operating in reverse breakdown mode. Its zener voltage is specified at IZT = 20 mA with <40 ms measurement delay to minimize self-heating effects, and its temperature coefficient is optimized near 0 mV/°C for 5.6 V devices per Figure 3 of DS31987.
The device uses a planar epitaxial construction in a molded plastic SOD323F package with matte tin–annealed copper alloy leads. It exhibits stable reverse characteristics up to 150 °C ambient, with power derating beginning at 25 °C per the linear curve in Figure 1 (RθJA = 250 °C/W).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 5.61–5.91 V @ IZT = 20 mA - defines regulated output voltage range under standard test conditions |
| Zener Impedance (ZZT) | ≤80 Ω @ f = 1 kHz - ensures minimal AC ripple transmission in reference applications |
| Power Dissipation (PD) | 500 mW on FR-4 PCB (10 mm × 10 mm pad) - sets maximum continuous DC or pulsed power handling |
| Reverse Leakage (IR) | ≤7.5 µA @ VR = 2 V - guarantees low standby current in high-impedance bias networks |
| Thermal Resistance (RθJA) | 250 °C/W - determines junction temperature rise above ambient under given power load |
| Operating Temperature | –65 °C to +150 °C - supports extended industrial and automotive under-hood environments |
| Package | SOD323F - ultra-small 2-pin surface-mount outline (2.50 mm × 1.25 mm × 0.95 mm) with cathode band marking |
Pinout & Package
SOD323F is a 2-terminal surface-mount package with cathode identified by a band on the top surface. The device has no internal circuitry beyond the Zener junction; terminals are unidirectional anode/cathode with no active control logic or auxiliary pins.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal / Zener cathode reference ground | Connected to lower-potential node in reverse-biased configuration; forms return path for zener current |
| Cathode | Zener breakdown terminal / regulated output node | Connected to higher-potential rail; provides stable voltage reference point when reverse biased above VZ |
Key Features
| Feature | Design Value |
|---|---|
| Precision Zener voltage tolerance | ±2.7% (5.61–5.91 V range) enables accurate voltage references without external trimming |
| Low dynamic impedance | ≤80 Ω at 1 kHz ensures minimal output voltage variation under varying load currents |
| Automated assembly compatibility | SOD323F footprint and matte tin finish support high-yield reflow soldering per J-STD-020 Level 1 |
| High-temperature operation | Rated to +150 °C junction temperature allows use in engine control units and industrial motor drives |
| Green compliance | Halogen- and antimony-free (<900 ppm Br/Cl, <1000 ppm Sb), fully RoHS 3 compliant |
Applications
| Power Supply Feedback | ADC Reference Stabilization |
|---|---|
|
Use Scenario: Regulating output voltage in isolated flyback or buck-boost converters via optocoupler-coupled feedback loop. IC Role / Device Role / Timing Role: Zener diode serves as primary-side voltage reference for TL431-like comparator circuits or direct feedback to PWM controller error amplifier. Use Value: Tight 5.61–5.91 V tolerance ensures ±1% output regulation accuracy without trimming resistors. |
Use Scenario: Providing stable reference voltage to 12-bit SAR ADCs in sensor signal conditioning front-ends. IC Role / Device Role / Timing Role: Acts as low-noise, low-drift voltage source replacing larger-footprint shunt references in space-constrained modules. Use Value: 80 Ω zener impedance minimizes reference voltage modulation from ADC sampling current transients. |
| Overvoltage Clamp | Microcontroller Reset Circuit |
|
Use Scenario: Protecting I/O pins of microcontrollers or FPGAs against ESD-induced voltage surges exceeding 6 V. IC Role / Device Role / Timing Role: Functions as fast-acting shunt clamp that conducts excess energy to ground when input exceeds VZ. Use Value: 500 mW power rating sustains transient clamping for >100 µs pulses without thermal runaway. |
Use Scenario: Generating precise reset threshold for 5 V microcontrollers requiring brown-out detection at 4.75 V. IC Role / Device Role / Timing Role: Forms part of resistor-divider network feeding reset supervisor IC or internal BOD circuit. Use Value: Low 7.5 µA reverse leakage at 2 V prevents significant divider current error in high-impedance reset networks. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C5V6 | Same 5.6 V nominal, but ±5% tolerance (5.32–5.88 V); 90 Ω ZZT; SOT-23 package | Larger footprint; higher impedance reduces regulation accuracy in precision feedback | Select when cost sensitivity outweighs voltage accuracy and board space is not constrained |
| MMSZ5232BS | 5.6 V nominal, ±5% tolerance; 100 Ω ZZT; SOD-123 package; 350 mW rating | Lower power rating limits surge handling; less suitable for sustained clamp duty | Prefer only for low-duty-cycle reference use where thermal margin is sufficient |
Compared with BZX84-C5V6 and MMSZ5232BS, DDZ5V6CSF-7 delivers tighter voltage tolerance, lower dynamic impedance, and higher power dissipation in a smaller SOD323F package-making it optimal for space-constrained, high-accuracy voltage regulation in automotive and industrial systems.

FAQ
What is the maximum continuous reverse current this Zener can handle at 25°C?
The DDZ5V6CSF-7 is rated for 20 mA zener test current (IZT) and supports continuous reverse current up to this value at 25°C ambient. Derating applies above 25°C per the linear power curve in Figure 1 of DS31987, with full 500 mW dissipation only valid below 25°C.
Does this part meet AEC-Q200 requirements for automotive use?
While DDZ5V6CSF-7 is manufactured in IATF 16949-certified facilities and supports PPAP documentation, it is not formally qualified to AEC-Q200. For certified automotive applications, Diodes recommends contacting their local representative to confirm qualification status or select an AEC-Q200–qualified variant.
Can this Zener be used in parallel for higher power handling?
No-parallel connection of Zener diodes is not recommended due to mismatched breakdown voltages causing current hogging. Each DDZ5V6CSF-7 must be used individually with appropriate series limiting resistors; higher power needs require discrete heat sinking or alternative topology such as series-pass regulation.
What is the significance of the 'CSF' suffix in the part number?
The 'CSF' suffix denotes the third voltage grade (tightest tolerance band) within the DDZ5V6 family and confirms SOD323F packaging. Per the Electrical Characteristics table, 'CSF' corresponds to 5.61–5.91 V range and YN marking code, distinguishing it from ASF (wider) and BSF (intermediate) variants.
