Product details
Overview
DZ9F11S92-7 from Diodes Incorporated is a surface-mount Zener diode with nominal zener voltage of 11 V, ±5% tolerance (10.45–11.55 V), 5 mA test current, and 30 Ω maximum zener impedance at 1 kHz. It features ultra-small SOD923 package (1.0 × 0.6 × 0.37 mm), 200 mW power dissipation, and −0.1 µA reverse leakage at 8 V, used for precision voltage regulation in space-constrained portable electronics.
For engineers reviewing the DZ9F11S92-7 datasheet, DZ9F11S92-7 pinout, DZ9F11S92-7 application, or DZ9F11S92-7 equivalent, key selection criteria include zener voltage stability over temperature (TC = +5.4 mV/°C), low capacitance (80 pF @ 1 MHz), thermal resistance (625 °C/W), and RoHS-compliant, halogen-free construction suitable for high-density PCB layouts.
Technical Context
This Zener diode operates in reverse breakdown to maintain stable reference voltage under varying load and temperature conditions. Its flat-lead SOD923 package enables efficient heat transfer from junction to PCB, supporting continuous operation up to +150°C ambient with derated power above +25°C.
The device exhibits low dynamic impedance (30 Ω @ 5 mA) and tight voltage tolerance, enabling accurate voltage clamping in low-power analog circuits. Its −0.1 µA reverse current at VR = 8 V ensures minimal standby power loss in battery-powered systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 11 V nominal, 10.45–11.55 V range at IZT = 5 mA - defines precise clamping threshold for 12 V rail protection |
| Zener Impedance (ZZT) | 30 Ω max @ 1 kHz - ensures minimal output voltage variation under dynamic load changes |
| Power Dissipation (PD) | 200 mW @ TA = +25°C - supports continuous regulation in compact, unheatsinked layouts |

FAQ
What is the maximum reverse voltage this Zener can withstand before breakdown?
The DZ9F11S92-7 has a nominal zener voltage of 11 V with a guaranteed range of 10.45–11.55 V at 5 mA test current. Breakdown occurs within this range; it is not rated for sustained operation above 11.55 V in reverse bias. Operation beyond this risks irreversible degradation.
Can this device be used in place of a 12 V Zener in a voltage reference circuit?
No - DZ9F11S92-7 is specified at 11 V nominal (10.45–11.55 V), not 12 V. Substituting it for a 12 V Zener would result in ~1 V lower reference voltage, potentially causing undervoltage lockout or incorrect ADC scaling. Use DZ9F12S92-7 for 12 V applications.
Is the SOD923 package compatible with standard 0402 pick-and-place equipment?
Yes - the SOD923 package (1.0 × 0.6 mm) matches the footprint and tape-and-reel pitch (8 mm) of standard 0402 components. Its flat-lead geometry and visible cathode band support reliable vision-based alignment and placement yield >99.95% in production-grade SMT lines.
Does this Zener diode require external heat sinking in typical operation?
No - the SOD923 package achieves 625 °C/W thermal resistance on standard FR-4 PCB with recommended pad layout. At 200 mW dissipation and +25°C ambient, junction temperature rise is ~125°C, staying within the −65°C to +150°C operating range without added heatsinking.
