Product details
Overview
DZ9F3V6S92-7 from Diodes Incorporated is a surface-mount Zener diode with a nominal zener voltage of 3.6 V, ±5% tolerance (3.42–3.78 V), 100 Ω maximum zener impedance at 5 mA test current, and 200 mW power dissipation in SOD923 package. It provides precision voltage regulation in space-constrained power management circuits such as USB port protection and low-voltage microcontroller reference rails.
For engineers reviewing the DZ9F3V6S92-7 datasheet, DZ9F3V6S92-7 pinout, DZ9F3V6S92-7 application, or DZ9F3V6S92-7 equivalent, key selection criteria include zener voltage accuracy, thermal resistance (625 °C/W), reverse leakage (≤10 µA at 1 V), and ultra-small footprint compatibility with high-density PCB layouts.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain stable voltage across load variations. Its flat-lead SOD923 package enables efficient heat transfer from junction to ambient air, supporting reliable operation up to +150°C junction temperature.
It exhibits a negative temperature coefficient of −3.5 mV/°C at 5 mA, ensuring predictable drift behavior in temperature-sensitive references. Capacitance is fixed at 210 pF at 0 V bias and 1 MHz, making it suitable for low-frequency regulation rather than RF bypassing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 3.6 V nominal, 3.42–3.78 V range at 5 mA - defines regulated output voltage under typical bias conditions |
| Power Dissipation (PD) | 200 mW at +25°C - sets maximum continuous power handling on standard FR-4 PCB |
| Zener Impedance (ZZT) | ≤100 Ω at 5 mA - determines regulation stiffness against load current changes |
| Reverse Leakage (IR) | ≤10 µA at 1 V reverse bias - ensures minimal quiescent current in standby mode |
| Thermal Resistance (RθJA) | 625 °C/W - quantifies junction-to-ambient temperature rise per watt dissipated |
| Capacitance (CT) | 210 pF at 0 V, 1 MHz - impacts AC noise filtering capability in DC rails |
| Operating Temperature | −65°C to +150°C - supports industrial and automotive under-hood environments |
Pinout & Package
The DZ9F3V6S92-7 is housed in an SOD923 surface-mount package (1.0 × 0.6 × 0.37 mm) with two terminals: anode and cathode marked by a visible band on the top surface. The exposed leadframe design eliminates need for X-ray inspection of solder joints.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to lower-potential node during normal forward bias; tied to ground or return path in shunt regulator configuration |
| Cathode | Zener breakdown terminal | Connected to regulated voltage node; marked with visible band for polarity identification and orientation control during placement |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-small footprint | 1.0 × 0.6 mm SOD923 package saves >60% board area vs. SOD-123 in dense portable designs |
| Thermally efficient leadframe | Exposed alloy-42 leadframe with matte tin finish improves heat dissipation over standard plastic packages |
| No X-ray inspection required | Flat-leaded, visibly exposed terminals enable optical verification of solder joint integrity |
| Green compliance | Halogen- and antimony-free (<900 ppm Br/Cl, <1000 ppm Sb) meets IPC-1752 and RoHS 2 requirements |
Applications
| USB Power Rail Protection | Microcontroller Voltage Reference |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX384-B3V6,115 (Nexperia) | Same 3.6 V nominal, but SOD-323 package (1.7 × 1.3 mm); 300 mW PD; 110 Ω ZZT | Larger footprint; higher power rating suits higher-current regulation | Select when board space allows and >200 mW dissipation is needed |
| MMSZ4685-7-F (Diodes Inc.) | SOD-123 package (3.7 × 1.6 mm); 500 mW PD; 150 Ω ZZT; same −3.5 mV/°C TC | 3.7× larger area; higher thermal mass reduces self-heating in pulsed loads | Choose for legacy designs using SOD-123 footprints or where derating margin is critical |
Compared with BZX384-B3V6 and MMSZ4685-7-F, DZ9F3V6S92-7 offers the smallest PCB footprint and lowest thermal resistance per unit area, making it optimal for miniaturized wearables and ultra-thin consumer electronics where space and thermal density are constrained.

FAQ
What is the maximum reverse voltage this Zener can withstand before breakdown?
The DZ9F3V6S92-7 has a nominal zener voltage of 3.6 V with a guaranteed range of 3.42 V to 3.78 V at 5 mA test current. Breakdown occurs within this range and is not defined as a single "maximum" value - instead, the device regulates stably across its specified VZ tolerance band under controlled current conditions.
Can this part be used in place of a 3.3 V Zener diode?
No - DZ9F3V6S92-7 is rated for 3.6 V nominal regulation and is not interchangeable with 3.3 V Zeners like DZ9F3V3S92-7. Substituting would raise the regulated voltage by ~0.3 V, potentially exceeding absolute maximum ratings of downstream 3.3 V logic or analog components.
Is the SOD923 package compatible with standard reflow profiles?
Yes - the SOD923 package is qualified for IPC/JEDEC J-STD-020 moisture sensitivity level 1 and supports standard lead-free reflow profiles (peak 260°C, 60-second duration). Its 0.2 mm lead width and flat-lead geometry ensure robust solder joint formation without tombstoning.
Does this Zener diode have a specified failure mode under overvoltage stress?
Per Diodes Incorporated's reliability data, the DZ9F3V6S92-7 fails open-circuit under sustained overvoltage or overcurrent conditions beyond its 200 mW power limit. This fail-safe behavior prevents short-circuit damage to upstream power sources or adjacent circuitry in protected systems.
