Product details

Overview

DZ23C3V0-7-F from Diodes Incorporated is a dual common-cathode 3.0 V Zener diode pair in SOT23 package, rated for 300 mW total power dissipation, with matched zener voltage tolerance (2.8–3.2 V) and low dynamic impedance (95 Ω @ 5 mA). It serves precision voltage reference and dual-rail clamping in low-power analog monitoring circuits, such as sensor biasing and ADC input protection.

For engineers reviewing the DZ23C3V0-7-F datasheet, DZ23C3V0-7-F pinout, DZ23C3V0-7-F application, or DZ23C3V0-7-F equivalent, key selection criteria include matched zener voltage tracking (≤5% ΔV_Z), common-cathode topology for shared reference node, thermal resistance (417 °C/W), and JEDEC-qualified reliability for industrial temperature range (−65 to +150 °C).

Technical Context

This dual Zener operates with both anodes electrically isolated and cathodes internally joined, enabling simultaneous regulation of two independent supply rails referenced to a single node. Each diode exhibits a nominal zener voltage of 3.0 V with ±0.2 V tolerance and a negative temperature coefficient of −0.060 %/°C.

It delivers stable breakdown at I_ZT = 5.0 mA with Z_ZT = 95 Ω and maintains low leakage (<0.1 µA @ V_R = 1.0 V), supporting low-current biasing in battery-powered instrumentation and signal conditioning front-ends.

Key Specifications

Parameter	Value and Actual Design Meaning
Zener Voltage (V_Z)	2.8–3.2 V @ I_ZT = 5 mA - Ensures tight dual-rail reference matching within one package.
Power Dissipation (P_D)	300 mW - Supports continuous operation in compact SOT23 layout without forced cooling.
Zener Impedance (Z_ZT)	95 Ω @ 5 mA - Minimizes output voltage variation under load current changes.
Temperature Coefficient	−0.060 %/°C - Predictable downward drift enables compensation in temperature-sensitive references.
Thermal Resistance (R_θJA)	417 °C/W - Requires minimal PCB copper area for thermal management on FR4.
Operating Temperature	−65 to +150 °C - Qualified for extended industrial and automotive ambient environments.

Applications

Industrial Sensor Signal Conditioning

Low-Power ADC Reference Clamping

Use Scenario: Biasing and overvoltage protection for bridge-based pressure/temperature sensors operating from 3.3 V rails.

IC Role / Device Role / Timing Role: Dual Zener provides matched 3.0 V clamp thresholds on excitation and output lines to prevent ADC saturation.

Use Value: Common-cathode architecture ensures identical reference potential, eliminating offset error between sensor channels.

Use Scenario: Protecting SAR ADC inputs in portable data loggers powered by coin-cell batteries.

IC Role / Device Role / Timing Role: Limits input voltage swing to ±3.0 V while drawing <0.1 µA leakage at sub-threshold bias.

Use Value: 300 mW rating allows safe transient absorption without thermal runaway during ESD events.

Dual-Rail Power Monitor Circuit

Microcontroller I/O Level Translation

Use Scenario: Monitoring 3.3 V and 5.0 V system rails in programmable logic controllers using a single ADC channel.

IC Role / Device Role / Timing Role: Two independent Zeners scale each rail to a common 3.0 V reference for ratiometric measurement.

Use Value: Matched V_Z tolerance (≤5%) ensures measurement accuracy better than ±1.5% across temperature.

Use Scenario: Interfacing 1.8 V microcontroller GPIOs with 3.3 V peripheral buses in IoT edge nodes.

IC Role / Device Role / Timing Role: Clamps bidirectional signals to 3.0 V maximum while preserving logic low threshold via common cathode tie to MCU ground.

Use Value: Low Z_ZT (95 Ω) maintains fast edge integrity during level-shifting transitions up to 1 MHz.

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
BZX384-C3V0 (Nexperia)	Single 3.0 V Zener in SOD323; no dual configuration or voltage matching spec.	Requires two separate devices and external matching; higher board area and BOM count.	Select when only one rail needs clamping or when cost-per-diode is prioritized over matching.
DZ23C3V3-7-F (Diodes Inc.)	Identical dual-common-cathode SOT23 package but 3.3 V nominal (3.1–3.5 V range); +0.055 %/°C TC.	Higher reference voltage suits 3.3 V logic margin requirements; less suitable for sub-3.0 V sensor biasing.	Select when system design requires tighter headroom above 3.0 V or positive TC compensation is needed.

Compared with BZX384-C3V0 and DZ23C3V3-7-F, DZ23C3V0-7-F uniquely delivers factory-matched 3.0 V dual regulation in one footprint-critical for differential sensing, dual-rail monitoring, and space-constrained mixed-signal designs where voltage tracking and thermal coupling matter.

FAQ

What is the maximum reverse current (I_R) specification for DZ23C3V0-7-F at 1.0 V?

The datasheet specifies minimum reverse voltage (V_R) as "-" for DZ23C3V0, indicating no guaranteed breakdown threshold below 2.8 V. At 1.0 V reverse bias, leakage remains below 0.1 µA per diode - confirmed by test condition notes and typical curves showing sub-nA behavior below V_Z.

Can DZ23C3V0-7-F be used in automotive applications?

Yes - the base DZ23C3V0-7-F is commercial-grade, but Diodes offers automotive-qualified equivalents (e.g., DZ23C3V0Q-7-F) with AEC-Q101 qualification, PPAP capability, and IATF 16949 manufacturing. These variants share identical electrical specs and SOT23 packaging but add automotive change control and traceability.

How does the common-cathode configuration affect PCB layout compared to discrete Zeners?

The common-cathode structure reduces net count by one, eliminates need for separate cathode traces, and ensures identical thermal environment for both diodes - improving voltage tracking over temperature. Layout requires only three pads (two anodes + shared cathode), with recommended SOT23 pad dimensions (2.0 × 0.8 mm body, 1.35 mm X1 spacing) published by Diodes.

Is the 300 mW power rating shared between both Zeners or per diode?

The 300 mW rating is total device power dissipation - not per diode. The datasheet's Thermal Characteristics table lists P_D = 300 mW unambiguously for the entire DZ23C2V7–DZ23C51 family. Simultaneous full-power operation of both diodes exceeds this limit; derating per Fig. 1 applies based on ambient temperature and PCB copper area.
