Product details
Overview
DZ9F4V1S92-7 from Diodes Incorporated is a surface-mount Zener diode with nominal zener voltage 4.1 V, ±5% tolerance (3.94–4.36 V), 200 mW power dissipation, 100 Ω maximum zener impedance at 5 mA test current, and 210 pF capacitance at 0 V. It operates in portable power management circuits for voltage reference and overvoltage clamping.
For engineers reviewing the DZ9F4V1S92-7 datasheet, DZ9F4V1S92-7 pinout, DZ9F4V1S92-7 application, or DZ9F4V1S92-7 equivalent, key selection criteria include zener voltage accuracy, thermal resistance (625 °C/W), ultra-small SOD923 footprint (1.0 × 0.6 mm), reverse leakage (5 µA @ 1 V), and RoHS-compliant matte tin terminations.
Technical Context
This Zener diode functions as a precision voltage reference and transient clamp in low-power analog and mixed-signal circuits. Its flat-lead SOD923 package enables high thermal efficiency and eliminates need for X-ray inspection due to exposed terminals.
It exhibits a temperature coefficient of −3.5 mV/°C at 5 mA, ensuring stable regulation across industrial temperature range (−65 to +150 °C), and maintains ≤210 pF junction capacitance at 0 V bias-critical for noise-sensitive signal conditioning paths.

FAQ
What is the maximum reverse voltage this Zener diode can withstand before breakdown?
The DZ9F4V1S92-7 has a nominal zener voltage of 4.1 V with a guaranteed range of 3.94–4.36 V at 5 mA test current. Its absolute maximum reverse voltage is defined by its breakdown characteristic-not a fixed "withstand" rating-and begins regulating within that specified range. It is not rated for sustained operation above 4.36 V in zener mode.
Does this device require a heatsink in standard PCB layouts?
No. With a thermal resistance of 625 °C/W on FR-4 and 200 mW maximum power dissipation, the DZ9F4V1S92-7 remains within safe junction temperature limits (<150 °C) under typical ambient conditions (≤70 °C) without heatsinking-provided the recommended SOD923 pad layout per Diodes' package outline is used.
Can this Zener diode be used in AC signal clipping applications?
Yes-its symmetric forward voltage (~0.9 V) and controlled zener breakdown enable bidirectional clipping. However, its 210 pF capacitance may attenuate signals above ~1 MHz; for RF clipping, lower-capacitance alternatives like DZ9F2V7S92 (same package, 2.7 V, 210 pF) or dedicated clipping diodes should be evaluated.
Is the SOD923 package compatible with standard reflow profiles for lead-free assembly?
Yes. The DZ9F4V1S92-7 is fully RoHS-compliant with matte tin annealed terminations and rated for moisture sensitivity level 1 (J-STD-020). It supports standard IPC/JEDEC J-STD-020 Class 3 reflow profiles, including peak temperatures up to 260 °C for ≤30 seconds, with no pre-bake required.
