Product details

Overview

DZ23C9V1-7-F from Diodes Incorporated is a dual common-cathode 300mW surface-mount Zener diode pair with nominal zener voltage 9.1V (8.5–9.6V range), maximum zener impedance 10Ω at 5mA, temperature coefficient +0.065%/°C, and minimum reverse voltage 7.0V at 0.1µA leakage - used for precision voltage reference and overvoltage clamping in power supply feedback loops.

For engineers reviewing the DZ23C9V1-7-F datasheet, DZ23C9V1-7-F pinout, DZ23C9V1-7-F application, or DZ23C9V1-7-F equivalent, key selection criteria include dual-zener matching (ΔV_Z ≤ 5%), SOT23 thermal resistance (417°C/W), JEDEC-qualified reliability, RoHS/Green compliance, and common-cathode topology for bidirectional regulation.

Technical Context

This dual Zener operates in common-cathode configuration: Pins 1 and 2 are anodes, Pin 3 is shared cathode. Each diode regulates independently with matched breakdown voltages within ±5% tolerance across the same die.

It delivers stable reference performance under 5mA test current, with low dynamic impedance (10Ω) and positive temperature coefficient (+0.065%/°C), enabling predictable drift compensation in analog feedback networks and protection circuits.

Key Specifications

Parameter	Value and Actual Design Meaning
Zener Voltage Range	8.5–9.6 V at I_ZT = 5 mA - defines usable regulation window for feedback sensing or clamp threshold setting
Zener Impedance	10 Ω max at I_ZT = 5 mA - ensures minimal output voltage variation under load transients
Temperature Coefficient	+0.065 %/°C - enables predictable upward drift with temperature, useful for offset compensation
Power Dissipation	300 mW - sets maximum continuous DC power handling on FR4 PCB with recommended pad layout
Thermal Resistance	417 °C/W junction-to-ambient - determines temperature rise per milliwatt under natural convection cooling
Reverse Leakage	0.1 µA at V_R = 7.0 V - confirms sharp knee and low standby current in clamp mode

Pinout & Package

Package: SOT23 - surface-mount plastic package with matte tin-plated alloy 42 lead frame, UL 94V-0 rated molding compound, moisture sensitivity level 1.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1	Anode of Zener Diode 1	Connects to regulated node or feedback path requiring 9.1V reference
Pin 2	Anode of Zener Diode 2	Enables independent second regulation path or differential sensing configuration
Pin 3	Common Cathode	Shared return node; ties both Zeners to system ground or bias rail

Key Features

Feature	Design Value
Dual Zeners, Common Cathode	Enables compact dual-rail referencing or bidirectional overvoltage protection without external wiring
ΔV_Z ≤ 5% Matching	Ensures consistent regulation thresholds between diodes on same die - critical for differential sensing
JEDEC High-Reliability Qualification	Validated for industrial and automotive-adjacent applications where long-term parametric stability matters
Lead-Free & Halogen-Free "Green" Construction	Complies with RoHS 3 (2015/863/EU), <900 ppm Br/Cl, <1000 ppm Sb - supports eco-design and export compliance

Applications

Switch-Mode Power Supply Feedback

Overvoltage Protection Clamp

Use Scenario: Regulating output voltage in isolated flyback or forward converters using optocoupler-coupled feedback.

IC Role / Device Role / Timing Role: Provides precise 9.1V reference at TL431 input or directly biases error amplifier input.

Use Value: Tight ΔV_Z matching ensures stable loop gain; low Z_ZT minimizes regulation error under varying load conditions.

Use Scenario: Protecting microcontroller I/O pins or ADC inputs from transient overvoltage events.

IC Role / Device Role / Timing Role: Clamps voltage to ≤9.6V during ESD or surge events while drawing minimal leakage (<0.1µA) at 7V.

Use Value: Dual-anode structure allows simultaneous clamping of two signals to same rail, reducing component count vs. discrete Zeners.

Differential Reference Generator

Temperature-Compensated Bias Network

Use Scenario: Generating matched positive/negative reference offsets for instrumentation amplifier front-ends.

IC Role / Device Role / Timing Role: Two matched 9.1V Zeners referenced to common cathode create symmetrical ±9.1V rails relative to mid-point.

Use Value: ≤5% V_Z mismatch ensures balanced offset cancellation; common-cathode topology eliminates inter-diode routing skew.

Use Scenario: Compensating thermal drift in op-amp bias networks or sensor excitation circuits.

IC Role / Device Role / Timing Role: Leverages +0.065%/°C TC to counteract negative TC of other components (e.g., resistors, transistors).

Use Value: Predictable positive drift enables first-order cancellation without active circuitry or trimming.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
BZX79-C9V1 (Nexperia)	Single Zener, DO-35 through-hole, 10% V_Z tolerance, 500mW rating	Lacks dual-element integration and common-cathode topology; requires two devices for equivalent function	Choose only if through-hole assembly or higher power dissipation (>300mW) is required
DZ23C9V1-Q-7-F	Automotive-grade variant qualified to AEC-Q101, identical electrical specs and SOT23 package	Requires PPAP documentation and IATF 16949 manufacturing traceability	Select when designing for automotive ECUs or systems requiring change-controlled qualification

Compared with BZX79-C9V1 and DZ23C9V1-Q-7-F, the DZ23C9V1-7-F uniquely combines dual-Zener integration, tight matching, and commercial-grade cost efficiency - making it optimal for space-constrained industrial power and protection designs where automotive certification is unnecessary.

FAQ

What is the maximum continuous power dissipation for DZ23C9V1-7-F?

The device is rated for 300 mW power dissipation when mounted on an FR4 PCB using Diodes' recommended pad layout. Derating begins above 25°C ambient, following the published curve: at 125°C ambient, maximum allowable power drops to approximately 150 mW due to thermal resistance of 417°C/W.

Can DZ23C9V1-7-F be used as a single Zener by leaving one anode unconnected?

Yes - Pin 1 or Pin 2 may be left floating or tied to a high-impedance node without affecting the operation of the other diode. However, both anodes share the same cathode (Pin 3), so unused anode must not be shorted or driven actively, as it remains electrically present on-die.

Is the temperature coefficient linear across the operating temperature range?

The +0.065%/°C coefficient is specified at 25°C and represents typical behavior near room temperature. Actual drift follows a parabolic curve per Figure 2 in DS18002; deviation exceeds ±10% of nominal TC below –25°C or above +100°C, requiring characterization for precision thermal compensation.

Does DZ23C9V1-7-F meet AEC-Q200 stress testing requirements?

No - DZ23C9V1-7-F is a commercial-grade part qualified to JEDEC standards. For AEC-Q200 compliance, the automotive variant DZ23C9V1-Q-7-F must be used, which undergoes additional temperature cycling, humidity bias, and mechanical shock testing per the AEC specification.
