Product details
Overview
DZ9F16S92-7 from Diodes Incorporated is a surface-mount Zener diode with nominal zener voltage 16 V (range 15.2–16.8 V), 5 mA test current, 50 Ω max zener impedance at 5 mA, 0.1 µA max reverse leakage at 12 V, and 65 pF capacitance at 1 MHz/0 V. It uses an ultra-small SOD923 package (1.0 × 0.6 × 0.37 mm) for space-constrained voltage regulation in portable power rails.
For engineers reviewing the DZ9F16S92-7 datasheet, DZ9F16S92-7 pinout, DZ9F16S92-7 application, or DZ9F16S92-7 equivalent, key selection criteria include zener voltage tolerance, low capacitance for signal integrity, thermal resistance (625 °C/W), and compatibility with automated optical inspection due to exposed terminals.
Technical Context
This Zener diode operates in reverse breakdown to maintain stable reference voltage under varying load or supply conditions. Its temperature coefficient of +10.4 mV/°C at 5 mA enables predictable drift compensation in precision analog circuits.
The SOD923 package features flat leads and exposed terminals for efficient heat dissipation and eliminates need for X-ray inspection of solder joints. Rated for −65 °C to +150 °C operation, it supports industrial and automotive ambient environments when mounted per recommended pad layout.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 16 V nominal, 15.2–16.8 V range at IZT = 5 mA - defines stable regulation point for 15–17 V rail clamping |
| Zener Impedance (ZZT) | 50 Ω max at 5 mA - limits output voltage variation under dynamic load changes |
| Reverse Leakage (IR) | 0.1 µA max at VR = 12 V - ensures minimal standby current in battery-powered systems |
| Capacitance (CT) | 65 pF at f = 1 MHz, VR = 0 V - preserves high-frequency signal integrity in RF bias networks |
| Power Dissipation (PD) | 200 mW at TA = 25 °C - sets maximum continuous power handling on standard FR-4 PCB |
| Thermal Resistance (RθJA) | 625 °C/W - determines junction temperature rise per mW dissipated without heatsinking |
| Operating Temperature | −65 °C to +150 °C - supports extended-range deployment in under-hood or outdoor electronics |
Pinout & Package
Package: SOD923 (1.0 × 0.6 × 0.37 mm), flat-lead, thermally efficient, with cathode band marking. Exposed terminals enable optical solder-joint verification.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal / Zener cathode reference ground | Connected to circuit ground or lower-potential node; forms reference return path during regulation |
| Cathode | Zener breakdown terminal / voltage clamp input | Connected to regulated node; conducts reverse current above 16 V to clamp overvoltage |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-small footprint | 1.0 × 0.6 mm body - enables placement in dense DC-DC converter feedback paths and sensor signal conditioning |
| Exposed terminals | No X-ray inspection required - reduces manufacturing QA cost and cycle time for high-volume SMT lines |
| Lead-free & green compliance | Halogen- and antimony-free (<900 ppm Br/Cl, <1000 ppm Sb) - meets IPC-1752A material declaration requirements |
| Low thermal resistance | 625 °C/W junction-to-ambient - allows 200 mW operation without derating below 70 °C ambient on minimal copper |
Applications
| Portable Power Management | Automotive Sensor Biasing |
|---|---|
Use Scenario: Voltage reference in Li-ion battery protection ICs and USB-C PD sink controllers. IC Role / Device Role / Timing Role: Zener clamp providing stable 16 V threshold for overvoltage detection logic. Use Value: Tight 15.2–16.8 V tolerance ensures reliable trip point across temperature without calibration. | Use Scenario: Bias voltage source for Hall-effect position sensors in EPS and throttle actuators. IC Role / Device Role / Timing Role: Stable 16 V supply rail for analog front-end amplifiers operating in 12 V vehicle systems. Use Value: 0.1 µA leakage at 12 V minimizes quiescent current draw in always-on sensor modules. |
| Industrial PLC Input Protection | RF Front-End DC Blocking |
Use Scenario: Overvoltage clamp on 24 V digital input channels subjected to inductive switching transients. IC Role / Device Role / Timing Role: Transient voltage suppressor limiting input to ≤16.8 V during surge events. Use Value: 50 Ω zener impedance ensures fast response to sub-µs spikes without overshoot. | Use Scenario: DC bias injection node in 2.4 GHz Wi-Fi front-end matching networks. IC Role / Device Role / Timing Role: Low-capacitance (65 pF) voltage reference shunt maintaining RF impedance stability. Use Value: Minimal 65 pF capacitance avoids detuning of λ/4 stubs and balun transformers. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX384-B16,115 (Nexperia) | Same 16 V nominal, but SOD323 package (1.7 × 1.3 mm); 150 mW PD; 90 pF CT | Larger footprint and higher capacitance limit use in RF or ultra-dense layouts | Select if board space permits and RF performance is not critical |
| MMSZ5245B-TP (Micro Commercial Components) | SOD-123 package (3.7 × 1.6 mm); 500 mW PD; 30 Ω ZZT; 100 pF CT | Higher power rating but 3× larger size and double capacitance vs. DZ9F16S92-7 | Prefer for high-power clamping where thermal margin >200 mW is required |
Compared with BZX384-B16 and MMSZ5245B-TP, DZ9F16S92-7 delivers the smallest footprint and lowest capacitance among 16 V Zeners, making it optimal for miniaturized, high-frequency, or thermally constrained designs where 200 mW dissipation suffices.

FAQ
What is the maximum power dissipation for DZ9F16S92-7 at 85°C ambient?
At 85°C ambient, DZ9F16S92-7 derates linearly from 200 mW at 25°C using 2.0 mW/°C slope. The allowable power is 200 mW − (85 − 25) × 2.0 = 80 mW. This assumes mounting on FR-4 PCB with Diodes' recommended SOD923 pad layout.
How is polarity identified on the DZ9F16S92-7 package?
Polarity is marked by a cathode band on the top surface of the SOD923 package, aligned with the cathode terminal. The band is visible without magnification and corresponds to the terminal opposite the chamfered corner in the top-view outline drawing.
Does DZ9F16S92-7 meet AEC-Q200 stress testing requirements?
No - DZ9F16S92-7 is not AEC-Q200 qualified. While rated for −65 °C to +150 °C operation and RoHS/halogen-free, it lacks the qualification test reports (e.g., temperature cycling, humidity bias) required for automotive-grade passive components.
Can DZ9F16S92-7 be used in place of a 1N4745A in a legacy design?
No - the 1N4745A is a 16 V, 1 W through-hole Zener in DO-41 package. DZ9F16S92-7 has only 200 mW rating and SOD923 footprint. Substitution requires verifying power handling, thermal layout, and PCB land pattern compatibility.
