Product details
Overview
DZ9F13S92-7 from Diodes Incorporated is a surface-mount Zener diode with nominal zener voltage 13 V (12.35–13.65 V), 5 mA test current, 37 Ω maximum zener impedance at IZT, and 75 pF capacitance at 1 MHz / 0 V. It uses an ultra-small SOD923 package (1.0 × 0.6 × 0.37 mm) with exposed terminals for visual solder-joint inspection and operates across −65 °C to +150 °C. It serves as a precision voltage reference in low-power analog sensing circuits.
For engineers reviewing the DZ9F13S92-7 datasheet, DZ9F13S92-7 pinout, DZ9F13S92-7 application, or DZ9F13S92-7 equivalent, key selection criteria include zener voltage tolerance (±5%), low dynamic impedance (37 Ω @ 5 mA), thermal resistance (625 °C/W), and compatibility with automated optical inspection due to flat-lead SOD923 packaging.
Technical Context
This device functions as a two-terminal voltage-regulating element operating in reverse breakdown. Its zener voltage exhibits a positive temperature coefficient of +7 mV/°C at 5 mA, enabling predictable drift compensation in temperature-stable references. The 0.1 µA maximum reverse leakage at 10 V supports low-quiescent-current bias networks.
The SOD923 package delivers 200 mW power dissipation at 25 °C with 2.0 mW/°C derating above ambient, and its 625 °C/W junction-to-ambient thermal resistance assumes FR-4 PCB mounting per Diodes' recommended pad layout. Cathode identification is marked by a visible band on the top surface.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX584-C13 | 13 V ±5%, 90 Ω ZZT @ 5 mA, SOD-523 package (1.2 × 0.8 mm) | Higher dynamic impedance increases output ripple in precision references | Select when board space allows larger footprint and cost sensitivity outweighs regulation stability |
| MMSZ4688 | 13 V ±5%, 30 Ω ZZT @ 5 mA, SOD-123 package (3.7 × 1.6 mm) | 3.7× larger footprint; higher RθJA (400 °C/W) requires thermal relief pads | Select when legacy layout compatibility or higher surge robustness (500 mW rating) is required |
Compared with BZX584-C13 and MMSZ4688, DZ9F13S92-7 delivers superior regulation stability in ultra-compact layouts due to its 37 Ω impedance and 625 °C/W thermal resistance-critical for miniaturized automotive and medical sensors where board area and thermal margin are constrained.

FAQ
What is the maximum power dissipation for DZ9F13S92-7 at 85°C ambient?
At 85°C ambient, DZ9F13S92-7 dissipates 80 mW. This is calculated using the 200 mW rating at 25°C and 2.0 mW/°C linear derating: 200 − (85 − 25) × 2.0 = 80 mW. Operation beyond this limit risks exceeding the 150°C maximum junction temperature.
How is cathode polarity identified on the SOD923 package?
The cathode is marked by a visible band on the top surface of the SOD923 package, aligned with the cathode terminal. This band is distinct and easily verifiable under optical inspection-no X-ray or electrical testing is needed to confirm orientation during placement.
Does DZ9F13S92-7 meet automotive AEC-Q200 stress testing requirements?
No-DZ9F13S92-7 is not AEC-Q200 qualified. While it operates across −65 °C to +150 °C and is RoHS-compliant, Diodes Incorporated does not list it in their AEC-Q200 qualified portfolio. For automotive-grade Zener diodes, consider the AZ series or contact Diodes Incorporated for qualified alternatives.
Can DZ9F13S92-7 be used in place of DZ9F12S92-7 in existing designs?
Yes, with circuit-level verification. DZ9F13S92-7 has a 13 V nominal zener voltage versus 12 V for DZ9F12S92-7-a 8.3% increase. This affects reference accuracy, bias point shifts, and thermal dissipation. Recalculate load current, power margin, and downstream ADC scaling before substitution.
