Product details

Overview

DZ23C13-7-F from Diodes Incorporated is a dual common-cathode 300mW surface-mount Zener diode with nominal zener voltage 13V (12.4–14.1V range), ±5% matching between diodes, and temperature coefficient +0.080%/°C - used for precision voltage reference and overvoltage protection in dual-rail power monitoring circuits.

For engineers reviewing the DZ23C13-7-F datasheet, DZ23C13-7-F pinout, DZ23C13-7-F application, or DZ23C13-7-F equivalent, key selection criteria include matched zener voltage tolerance, low thermal resistance (417°C/W), SOT23 package compatibility, and dual-diode common-cathode topology for rail-to-rail clamping.

Technical Context

This device integrates two independent Zener diodes sharing a single cathode terminal in a SOT23-3 package, enabling bidirectional voltage regulation or differential reference generation without external node coupling. It operates across –65°C to +150°C with JEDEC-qualified reliability and supports automated placement via lead-free matte tin terminations.

Zener impedance is specified at 25Ω (max) at I_ZT = 5mA and 110Ω (max) at I_ZK = 1mA, with minimum reverse voltage of 10.0V at I_R = 0.1µA - confirming stable breakdown behavior under low-leakage bias conditions typical in sensor biasing and analog front-end protection.

Key Specifications

Parameter	Value and Actual Design Meaning
Zener Voltage Range	12.4 V to 14.1 V at I_ZT = 5 mA - defines usable regulation window for 13 V nominal systems
Max Zener Impedance	25 Ω at I_ZT = 5 mA - ensures minimal output voltage shift under load transients
Temperature Coefficient	+0.080 %/°C - enables predictable drift compensation in temperature-stable references
Power Dissipation	300 mW - sets maximum continuous DC power handling on FR4 PCB with standard pad layout
Thermal Resistance	417 °C/W junction-to-ambient - determines allowable ambient rise before exceeding 150°C max junction temperature
Reverse Leakage	<0.1 µA at 10.0 V - guarantees negligible current draw in standby clamp configurations

Pinout & Package

Package: SOT23-3, plastic molded, green compound (UL 94V-0), 0.008 g mass, moisture sensitivity level 1.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1	Anode 1	First Zener anode - connects to lower-voltage rail or signal line requiring clamping
Pin 2	Cathode (Common)	Shared cathode node - ties both Zeners to regulated reference or supply rail
Pin 3	Anode 2	Second Zener anode - enables symmetrical or complementary clamping on opposite polarity rail

Key Features

Feature	Design Value

Equivalent & Alternatives

The following parts are listed as comparable options for similar dual-Zener voltage reference applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
BZX79-C13,113	Single Zener, DO-35 package, 12.35–13.65 V range, higher Z_ZT (30 Ω)	Requires two devices and board area for dual-rail use; no inherent matching	Select when cost-per-device priority outweighs board space and matching requirements
DZ23C12-7-F	12 V nominal (11.4–12.7 V), tighter V_Z tolerance (±4.2%), same package and pinout	Suitable where 12 V regulation is required instead of 13 V; identical layout reuse possible	Choose for legacy 12 V system upgrades needing drop-in replacement with improved matching

Compared with BZX79-C13,113 and DZ23C12-7-F, DZ23C13-7-F uniquely delivers matched dual-Zener performance in SOT23, enabling compact, thermally coupled voltage referencing unattainable with discrete or single-diode alternatives.

FAQ

What is the maximum continuous power dissipation for DZ23C13-7-F?

The device is rated for 300 mW total power dissipation on FR4 PCB with Diodes' recommended pad layout. Derating begins above 25°C ambient per the published curve: at 75°C ambient, maximum power drops to ~150 mW to maintain junction temperature ≤150°C.

How is the common cathode configuration implemented electrically?

Pin 2 is the internal connection point for both Zener cathodes. Pins 1 and 3 serve as independent anodes. This allows one diode to clamp positive excursions (Pin 1 → Pin 2) and the other to clamp negative excursions (Pin 3 → Pin 2) relative to the shared cathode node.

Does DZ23C13-7-F meet AEC-Q200 stress testing requirements?

No - DZ23C13-7-F is a commercial-grade part qualified to JEDEC standards. For automotive applications, Diodes offers the Q-suffix variant DZ23C13Q-7-F, which undergoes AEC-Q200 qualification and is manufactured in IATF 16949 certified facilities.

Can this device be used for ESD protection in USB data lines?

Not recommended - its 13 V breakdown voltage exceeds USB 2.0/3.0 signal swing limits (±0.3 V differential). It lacks specified C_T data below 10 V and is optimized for DC/low-frequency regulation, not high-speed transient suppression.
