Product details
Overview
DZ9F7V5S92-7 from Diodes Incorporated is a surface-mount Zener diode with nominal zener voltage 7.5 V (±4.5% tolerance), 30 Ω maximum zener impedance at 5 mA test current, and 0.5 µA maximum reverse leakage at 4 V. It uses an ultra-small SOD923 package (1.0 × 0.6 × 0.37 mm), rated for 200 mW power dissipation, and is optimized for precision voltage reference and overvoltage protection in space-constrained portable electronics.
For engineers reviewing the DZ9F7V5S92-7 datasheet, DZ9F7V5S92-7 pinout, DZ9F7V5S92-7 application, or DZ9F7V5S92-7 equivalent, key selection criteria include zener voltage stability across temperature (TC = +2.5 to +5.3 mV/°C), low capacitance (100 pF @ 1 MHz), thermal resistance (625 °C/W), and RoHS-compliant green packaging suitable for high-density PCB layouts.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain stable voltage regulation under varying load and temperature conditions. Its flat-lead SOD923 package enables efficient heat transfer from the junction to ambient air without requiring X-ray inspection due to exposed terminals.
The device exhibits a positive temperature coefficient (+2.5 to +5.3 mV/°C) above 5 V, enabling predictable drift compensation in reference circuits. It delivers 7.5 V regulation at 5 mA test current with tight ±4.5% initial tolerance and maintains ≤0.5 µA reverse leakage up to 4 V, supporting low-power standby functions.
Key Specifications

FAQ
What is the recommended PCB pad layout for DZ9F7V5S92-7?
Diodes Incorporated specifies a SOD923-compatible pad layout with 0.2 mm lead width, 0.60 mm pad length (D), and 0.80 mm pad width (E). The recommended design uses thermal relief vias under the exposed copper terminals to enhance heat dissipation. Full dimensions and Gerber recommendations are published in document DS37439 Rev. 5-2, Section "Suggested Pad Layout".
Does DZ9F7V5S92-7 meet AEC-Q200 stress testing requirements?
No-DZ9F7V5S92-7 is not AEC-Q200 qualified. It is rated for −65°C to +150°C operating temperature and meets J-STD-020 moisture sensitivity level 1, but lacks the extended temperature cycling, vibration, and accelerated life testing required for automotive qualification. For AEC-Q200 applications, consider Diodes' AZ-series automotive-grade Zeners.
Can DZ9F7V5S92-7 be used in series for higher voltage reference generation?
Yes-multiple DZ9F7V5S92-7 devices may be connected in series to achieve higher reference voltages (e.g., two in series yield ~15 V), but total zener impedance and temperature coefficient will sum linearly. Derating of total power dissipation must follow the 200 mW per device limit, and thermal coupling between devices must be considered to avoid localized overheating.
What is the meaning of the "-7" suffix in DZ9F7V5S92-7?
The "-7" suffix denotes tape-and-reel packaging: 10,000 units per reel in standard SOD923 carrier tape. This is the only ordering option for this part number; no bulk, cut-tape, or tray variants are offered. The base part number DZ9F7V5S92 is not orderable without the -7 suffix.
