Product details
Overview
DZ9F3V3S92-7 from Diodes Incorporated is a surface-mount Zener diode with nominal zener voltage 3.3 V (±3.6% tolerance), 5 mA test current, 100 Ω maximum zener impedance at 5 mA, −3.5 mV/°C temperature coefficient, and 210 pF capacitance at 1 MHz. It operates in ultra-small SOD923 package (1.0 × 0.6 × 0.37 mm), rated for 200 mW power dissipation and −65°C to +150°C junction temperature, and is used for precision voltage reference and overvoltage protection in space-constrained portable power rails.
For engineers reviewing the DZ9F3V3S92-7 datasheet, DZ9F3V3S92-7 pinout, DZ9F3V3S92-7 application, or DZ9F3V3S92-7 equivalent, key selection criteria include zener voltage stability under varying temperature and load, low dynamic impedance for regulation fidelity, thermal performance on FR-4 PCBs, and compatibility with automated optical inspection due to exposed terminals.
Technical Context
This Zener diode functions as a two-terminal voltage reference device operating in reverse breakdown mode. Its −3.5 mV/°C temperature coefficient indicates predictable, linear drift over temperature, enabling compensation in analog sensor biasing circuits. The 100 Ω zener impedance at 5 mA defines regulation error under load variation.
The SOD923 package features flat leads and an exposed cathode band for polarity identification, eliminating need for X-ray inspection of solder joints. Thermal resistance is 625 °C/W when mounted per Diodes' recommended pad layout, limiting usable power at elevated ambient temperatures.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 3.3 V nominal, 3.14–3.47 V range at 5 mA - ensures stable reference within ±3.6% across production lot |
| Power Dissipation (PD) | 200 mW at 25°C - supports low-power biasing without heatsinking on standard FR-4 |
| Zener Impedance (ZZT) | 100 Ω max at 5 mA - limits output voltage deviation under 1 mA load change to ≤100 mV |
| Temperature Coefficient (TC) | −3.5 mV/°C - enables predictable offset correction in temperature-sensitive references |
| Capacitance (CT) | 210 pF at 1 MHz, 0 V - constrains high-frequency noise filtering capability in RF-adjacent circuits |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX384-B3V3,115 (Nexperia) | Same 3.3 V nominal, but SOD323 package (1.3 × 0.8 mm); 90 Ω ZZT; −2.5 mV/°C TC | Larger footprint; slightly better impedance but less negative TC reduces cold-temperature drift | Select if board layout permits larger package and tighter impedance is prioritized over thermal tracking |
| MMSZ4685T1G (onsemi) | SOD123 package (3.7 × 1.6 mm); 3.3 V nominal; 120 Ω ZZT; −3.0 mV/°C TC; 350 mW PD | 3.7× larger area; higher power handling but poorer thermal resistance (400 °C/W) and higher capacitance (300 pF) | Select only when >200 mW dissipation is required and board space is unconstrained |
Compared with BZX384-B3V3 and MMSZ4685T1G, DZ9F3V3S92-7 offers the smallest footprint and best thermal match for temperature-critical references, though its 100 Ω impedance sits between the two alternatives-making it optimal for compact, thermally stable 3.3 V biasing where space is premium.

FAQ
What is the maximum reverse voltage before breakdown for DZ9F3V3S92-7?
The DZ9F3V3S92-7 exhibits sharp reverse breakdown at 3.3 V nominal, with guaranteed minimum breakdown voltage of 3.14 V and maximum of 3.47 V at 5 mA test current. Below 3.14 V, reverse leakage remains ≤10 µA at 1 V, confirming no premature conduction.
Can DZ9F3V3S92-7 be used in place of a 3.3 V LDO for low-current biasing?
No-it is not a regulator IC. As a two-terminal Zener, it requires a series current-limiting resistor and cannot maintain regulation under variable load or input voltage. It delivers stable voltage only when reverse current is held within 1–10 mA; use only for fixed-load references or clamping, not active regulation.
Is the SOD923 package compatible with standard 0402 reflow profiles?
Yes-the SOD923 (1.0 × 0.6 mm) matches 0402 land pattern dimensions and is qualified for IPC/JEDEC J-STD-020 Level 1 moisture sensitivity. Diodes' recommended pad layout (0.55 × 0.75 mm pads, 0.3 mm solder mask opening) ensures reliable reflow yield with standard lead-free profiles.
Does DZ9F3V3S92-7 meet AEC-Q200 for automotive use?
No-while it operates from −65°C to +150°C and is RoHS/halogen-free, Diodes does not qualify this part to AEC-Q200. For automotive applications, consider Diodes' AEC-Q200-qualified BZT52 series in SOD-123 or SMA packages instead.
