Diodes Incorporated DZ9F10S92-7

Overview

DZ9F10S92-7 from Diodes Incorporated is a surface-mount Zener diode with nominal 10 V zener voltage (9.50–10.50 V at 5 mA), 30 Ω maximum zener impedance at test current, ±0.1 µA maximum reverse leakage at 7 V, and 200 mW power dissipation in SOD923 package. It serves as a precision voltage reference or overvoltage clamp in low-power analog monitoring circuits.

For engineers reviewing the DZ9F10S92-7 datasheet, DZ9F10S92-7 pinout, DZ9F10S92-7 application, or DZ9F10S92-7 equivalent, key selection criteria include zener voltage tolerance, dynamic impedance at operating current, thermal resistance (625 °C/W), and SOD923 footprint compatibility with high-density PCB layouts.

Technical Context

This Zener diode operates in reverse breakdown mode with a temperature coefficient of +4.5 mV/°C at 5 mA, enabling predictable drift compensation in stable reference designs. Its ultra-small SOD923 package (1.0 × 0.6 × 0.37 mm) features exposed terminals for visual solder-joint inspection and a thermally efficient flat-lead structure.

The device exhibits 80 pF capacitance at 0 V reverse bias and 110 Ω maximum zener impedance at knee current (0.5 mA), supporting fast transient response in low-energy regulation paths. Rated for −65 °C to +150 °C operation, it maintains specified electrical performance across industrial temperature ranges without derating below +25 °C.

FAQ

What is the cathode marking convention for DZ9F10S92-7?

The cathode is marked by a visible band on the top surface of the SOD923 package, aligned with the cathode terminal. This matches industry-standard polarity identification for surface-mount Zeners and ensures correct orientation during automated placement.

Can DZ9F10S92-7 be used in place of a 1N4740A?

No - DZ9F10S92-7 is a 10 V, 200 mW SOD923 device with 30 Ω impedance, while 1N4740A is a 10 V, 1 W DO-41 part with ~20 Ω impedance. The packages, power ratings, and thermal profiles are incompatible; substitution requires PCB redesign and thermal validation.

What is the maximum allowable reverse voltage before breakdown?

The device begins controlled breakdown at its specified zener voltage (9.50–10.50 V). Below 7 V, reverse leakage remains ≤0.1 µA. Operation above 10.50 V is permissible only within the 200 mW power limit and thermal constraints defined in the derating curve.

Does DZ9F10S92-7 require special reflow profile considerations?

Yes - as a Level 1 moisture-sensitive device per J-STD-020, it may be reflowed without baking if stored properly. Peak reflow temperature must not exceed 260 °C, and the profile must comply with Diodes' SOD923 pad layout recommendations to avoid solder joint voiding or thermal stress cracking.
