Product details

Overview

DZ23C16-7-F from Diodes Incorporated is a dual common-cathode 300mW surface-mount Zener diode with nominal zener voltage 16V (15.3–17.1V range), ±5% matching between diodes, and 40Ω maximum zener impedance at 5mA test current - used for precision voltage reference and overvoltage clamping in dual-rail power monitoring circuits.

For engineers reviewing the DZ23C16-7-F datasheet, DZ23C16-7-F pinout, DZ23C16-7-F application, or DZ23C16-7-F equivalent, key selection criteria include matched dual-zener tolerance, SOT23 thermal resistance (417°C/W), temperature coefficient (+0.090%/°C), reverse leakage (<0.1µA at 12V), and JEDEC-qualified reliability for industrial power management designs.

Technical Context

This device integrates two independent Zener diodes sharing a common cathode terminal in a single SOT23 package, enabling compact dual-voltage regulation or bidirectional transient suppression without external node coupling. Its matched V_Z deviation ≤5% supports differential reference architectures.

The +0.090%/°C temperature coefficient ensures predictable drift across –65°C to +150°C operating range, while 300mW power dissipation and 417°C/W junction-to-ambient thermal resistance define safe DC and pulsed current limits under standard FR4 PCB mounting.

Key Specifications

Parameter	Value and Actual Design Meaning
Zener Voltage Range	15.3V to 17.1V at I_ZT = 5mA - defines usable regulation window for 16V nominal rail stabilization
Max Zener Impedance	40Ω at I_ZT = 5mA - limits output voltage variation under load changes in reference circuits
Temperature Coefficient	+0.090%/°C - quantifies positive V_Z drift per degree Celsius for thermal error budgeting
Power Dissipation	300mW - sets absolute maximum continuous DC power under JEDEC-standard PCB layout
Reverse Leakage	<0.1µA at V_R = 12.0V - ensures minimal quiescent current in high-impedance sensing nodes
Thermal Resistance	417°C/W junction-to-ambient - determines temperature rise per watt on standard FR4 board

Pinout & Package

Package: SOT23 - surface-mount plastic case with matte tin-plated alloy 42 leads, UL 94V-0 rated, 0.008g weight, moisture sensitivity level 1.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1 (Anode 1)	First Zener Anode	Connects to first regulated node; reverse-biased to achieve 16V breakdown

Equivalent & Alternatives

The following parts are listed as comparable options for similar dual Zener diode applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
BZX384-C16-Q	Single Zener only; same 16V nominal, 300mW, SOT23 but no dual configuration	Requires two devices for dual-rail use; lacks V_Z matching guarantee	Select when only one reference voltage is needed or board layout allows discrete placement
DZ23C15-7-F	15V nominal (13.8–15.6V range); identical dual-common-cathode structure and SOT23 package	Suitable for 15V system monitoring where tighter low-end tolerance is required	Choose for legacy 15V rail compatibility or lower-voltage margin requirements

Compared with BZX384-C16-Q and DZ23C15-7-F, DZ23C16-7-F uniquely delivers matched 16V dual-Zener performance in one SOT23 - critical for differential sensing and space-constrained dual-rail protection where V_Z tracking and footprint efficiency are design priorities.

FAQ

What is the maximum continuous reverse current this device can handle at 16V?

At 16V applied reverse voltage and 25°C ambient, DZ23C16-7-F draws less than 0.1µA - well below its 5mA test current rating. Continuous conduction is limited by power dissipation: 300mW / 16V ≈ 18.75mA maximum average current before exceeding thermal limits on standard FR4 PCB.

Can this dual Zener be used in avalanche mode for ESD protection?

No - DZ23C16-7-F is specified and characterized only for Zener breakdown operation. Its 17.1V upper V_Z limit and lack of defined ESD parameters (e.g., IEC 61000-4-2 rating) make it unsuitable as a dedicated ESD clamp; TVS diodes like PUSB3FR4 are recommended for that function.

Is the common cathode pin electrically isolated from the package substrate?

Yes - the SOT23 package uses a molded plastic body with matte tin-plated alloy 42 leads; the common cathode (Pin 2) is fully isolated from the thermal pad or substrate. No internal thermal slug or metal tab connects Pin 2 to package ground or heatsink surfaces.

Does this part meet AEC-Q200 stress testing requirements?

No - DZ23C16-7-F is commercial-grade (non-Q suffix). For automotive qualification, Diodes offers the Q-suffix variant DZ23C16Q-7-F, which undergoes AEC-Q200 testing and is manufactured in IATF 16949 certified facilities - confirmed via Diodes' automotive product portal.
