Diodes Incorporated DZ23C10-7-F

Overview

DZ23C10-7-F from Diodes Incorporated is a dual common-cathode 300mW surface-mount Zener diode with nominal zener voltage 10.0V (9.4–10.6V range), maximum zener impedance 15Ω at 5mA, temperature coefficient +0.065%/°C, and minimum reverse voltage 7.5V - used for precision voltage reference and overvoltage clamping in power supply feedback loops and analog sensor conditioning circuits.

For engineers reviewing the DZ23C10-7-F datasheet, DZ23C10-7-F pinout, DZ23C10-7-F application, or DZ23C10-7-F equivalent, key selection criteria include matched dual-zener tracking (≤5% ΔV_Z), SOT23 package compatibility with automated assembly, JEDEC-qualified reliability, and tight thermal resistance (417°C/W) for stable regulation under varying ambient conditions.

Technical Context

This dual-Zener device integrates two independent zener elements sharing a common cathode terminal, enabling bidirectional voltage clamping or dual-reference generation in compact space-constrained designs. Its common-cathode topology supports series-connected regulation paths without external node routing.

The device operates across –65°C to +150°C, with power derating beginning above 50°C ambient per the published curve. Thermal resistance of 417°C/W assumes FR4 PCB mounting with Diodes' recommended pad layout, directly impacting steady-state voltage stability under load.

FAQ

What is the maximum continuous current this dual Zener can handle at 10V?

At 10V nominal zener voltage and 300mW power rating, the absolute maximum continuous zener current is 30mA (P_D/V_Z = 300mW/10V). However, derating begins above 50°C ambient per Figure 1, limiting practical continuous current to ~22mA at 85°C ambient to maintain safe junction temperature.

Can Pin 1 and Pin 3 be used simultaneously for independent regulation paths?

Yes - Pin 1 (Anode 1) and Pin 3 (Anode 2) operate as fully independent zener anodes sharing only the common cathode (Pin 2). Each can regulate or clamp distinct circuit nodes, provided total power dissipation across both elements remains ≤300mW and thermal design accounts for combined self-heating.

Is the DZ23C10-7-F qualified for automotive AEC-Q200 stress testing?

No - the DZ23C10-7-F is commercial-grade and JEDEC-qualified, but not AEC-Q200 certified. For automotive applications, Diodes offers the Q-suffix variant DZ23C10Q-7-F, which undergoes AEC-Q200 testing, PPAP documentation, and is manufactured in IATF 16949-certified facilities.

How does the +0.065%/°C temperature coefficient affect long-term voltage stability?

Over the full –65°C to +150°C operating range, the +0.065%/°C coefficient causes a total zener voltage shift of approximately ±1.04V (10V × 0.00065 × 160°C), centered around 25°C. This translates to ±104 ppm/°C drift - acceptable for non-precision references but insufficient for metrology-grade applications without external compensation.
