Product details
Overview
DZ9F22S92-7 from Diodes Incorporated is a surface-mount Zener diode with nominal 22 V zener voltage (20.9–23.1 V range at 5 mA), 55 Ω maximum zener impedance at 5 mA, 15.4 mV/°C temperature coefficient, 55 pF capacitance at 1 MHz, and 0.1 µA maximum reverse leakage at 16.8 V. It serves as a precision voltage reference or overvoltage clamp in low-power analog signal conditioning circuits.
For engineers reviewing the DZ9F22S92-7 datasheet, DZ9F22S92-7 pinout, DZ9F22S92-7 application, or DZ9F22S92-7 equivalent, key selection criteria include its SOD923 ultra-small package (1.0 × 0.6 × 0.37 mm), 200 mW power rating, thermal resistance of 625 °C/W, and cathode-band polarity marking for unambiguous board-level orientation.
Technical Context
This Zener diode operates in reverse breakdown to maintain stable voltage regulation under controlled current conditions. Its −3.5 to +20 mV/°C temperature coefficient range (with +15.4 mV/°C typical at 5 mA for the 22 V variant) enables predictable drift compensation in reference designs.
The device uses an exposed-terminal SOD923 package with matte tin–annealed Alloy 42 leadframe, delivering low thermal resistance and eliminating need for X-ray inspection. Its 0.2 mm lead width and 1.0 mm body length support high-density PCB layouts in space-constrained consumer and industrial modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 22 V nominal, 20.9–23.1 V min/max at 5 mA - defines regulated output voltage tolerance in reference circuits |
| Max Zener Impedance (ZZT) | 55 Ω at 5 mA - determines voltage stability under load variation; lower value improves regulation accuracy |
| Temp Coefficient (TC) | +15.4 mV/°C at 5 mA - quantifies voltage drift with ambient temperature change; critical for wide-temperature operation |
| Capacitance (CT) | 55 pF at 1 MHz, 0 V - limits high-frequency noise coupling; suitable for DC/low-speed analog references |
| Power Dissipation (PD) | 200 mW at 25°C - sets maximum continuous dissipation before thermal derating begins |
| Reverse Leakage (IR) | 0.1 µA at 16.8 V - ensures minimal quiescent current in standby or battery-powered bias networks |
| Package | SOD923 (1.0 × 0.6 × 0.37 mm) - enables 0201-class footprint density with thermally efficient flat-lead construction |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX584C22 | 22 V, 500 mW, SOD-523, 110 Ω ZZT, −3.5 to +20 mV/°C TC | Higher power but larger footprint (1.3 × 0.85 mm); higher impedance reduces regulation precision | Select when higher power margin is needed and board space allows SOD-523 |
| MMSZ5248B | 22 V, 500 mW, SOD-123, 30 Ω ZZT, +15 mV/°C TC, 50 pF | Lower impedance and tighter TC, but 2.8 × 1.6 mm package occupies >7× more area than SOD923 | Select when ultimate regulation accuracy is prioritized over miniaturization |
Compared with BZX584C22 and MMSZ5248B, DZ9F22S92-7 uniquely balances ultra-miniature size, moderate impedance, and industry-standard TC in a thermally efficient flat-lead package-making it optimal for space-constrained, battery-sensitive, and thermally managed designs where 200 mW suffices.

FAQ
What is the maximum reverse voltage DZ9F22S92-7 can withstand before breakdown?
The device exhibits sharp Zener breakdown at 22 V nominal, with guaranteed regulation starting at 20.9 V and extending to 23.1 V at 5 mA test current. Its absolute maximum non-destructive reverse voltage is not specified beyond the 23.1 V upper limit of the Zener range; operation above this risks irreversible avalanche degradation. The 16.8 V reverse test voltage (where leakage is measured) is not a breakdown threshold but a stress point for leakage verification.
Does DZ9F22S92-7 require a heatsink in standard PCB layouts?
No heatsink is required. With a thermal resistance of 625 °C/W on FR-4 and 200 mW maximum power dissipation, junction temperature rise remains within safe limits (≤125°C) at ambient temperatures up to +75°C using Diodes Incorporated's recommended SOD923 pad layout. Derating begins linearly above +25°C at 2.0 mW/°C.
How is polarity identified on the DZ9F22S92-7 package?
Polarity is marked by a visible cathode band on the top surface of the SOD923 package - a thin, dark stripe aligned with the cathode terminal. This band is fully exposed and inspectable under optical magnification, eliminating need for X-ray verification. The anode is the opposite terminal, with no marking.
Can DZ9F22S92-7 be used in AC signal clipping applications?
Yes, but only in low-current, low-frequency contexts. Its 55 pF capacitance and 55 Ω dynamic impedance support clipping up to ~100 kHz with minimal distortion; however, forward voltage (0.9 V @ 10 mA) and limited surge capability restrict use to signal levels ≤±25 V and peak currents ≤10 mA. It is not rated for repetitive transient suppression.
