Product details

Overview

DZ23C6V8-7 from Diodes Incorporated is a dual common-cathode 300mW surface-mount Zener diode with nominal zener voltage 6.8V (6.4–7.2V range), 8.0Ω max zener impedance at 5mA, +0.045%/°C temperature coefficient, and SOT23 package - used for precision voltage reference and overvoltage protection in power supply feedback loops.

For engineers reviewing the DZ23C6V8-7 datasheet, DZ23C6V8-7 pinout, DZ23C6V8-7 application, or DZ23C6V8-7 equivalent, key selection criteria include matched dual-zener tracking (≤5% ΔV_Z), low thermal resistance (417°C/W), JEDEC-qualified reliability, RoHS/Green compliance, and compatibility with automated SMT assembly.

Technical Context

This device integrates two Zener diodes sharing a common cathode terminal in a single SOT23 package, enabling compact dual-reference or differential clamping topologies. Its ±5% V_Z matching between diodes supports tightly regulated feedback paths where voltage symmetry matters.

The zener operates at 5mA test current with 3.0V minimum reverse voltage and exhibits +0.045%/°C TC - indicating stable regulation across industrial temperature range (−65°C to +150°C) without significant drift.

Key Specifications

Parameter	Value and Actual Design Meaning
Zener Voltage	6.4–7.2V @ I_ZT = 5mA - defines tight regulation window for feedback sensing
Zener Impedance	8.0Ω max @ 5mA - ensures minimal output voltage variation under load transients
Power Dissipation	300mW - sets maximum continuous power handling on FR4 PCB with recommended pad layout
Temperature Coefficient	+0.045%/°C - guarantees predictable, low-drift voltage reference over temperature
Reverse Voltage	3.0V min @ I_R = 0.1µA - confirms reliable blocking behavior below breakdown threshold
Thermal Resistance	417°C/W - determines junction-to-ambient temperature rise under full power

Pinout & Package

Package: SOT23 - surface-mount plastic case with matte tin finish, UL 94V-0 rating, moisture sensitivity level 1, and 0.008g weight.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1	Anode of Diode 1	Independent anode connection for first Zener element
Pin 2	Cathode (Common)	Shared cathode node for both Zeners - primary reference/ground tie point
Pin 3	Anode of Diode 2	Independent anode connection for second Zener element

Key Features

Feature	Design Value

Applications

Switch-Mode Power Supply Feedback

Overvoltage Protection Circuit

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

IC Role / Device Role / Timing Role: Provides precise 6.8V reference to TL431 shunt regulator or directly biases error amplifier input.

Use Value: Tight 6.4–7.2V tolerance and low 8Ω impedance maintain ±1% output regulation under line/load changes.

Use Scenario: Clamping transient surges on 5V or 12V rail inputs in industrial control modules.

IC Role / Device Role / Timing Role: Dual-Zener structure allows bidirectional clamping (e.g., positive surge to V_CC, negative surge to GND).

Use Value: Common-cathode topology simplifies PCB layout and reduces component count versus discrete dual-diode solutions.

Automotive Sensor Reference

Industrial Analog Signal Conditioning

Use Scenario: Supplying stable bias voltage to pressure or temperature sensor bridges in engine control units.

IC Role / Device Role / Timing Role: Delivers low-drift 6.8V reference unaffected by ambient temperature swings (−40°C to +125°C).

Use Value: +0.045%/°C TC ensures <±0.3% reference shift over full automotive temperature range.

Use Scenario: Level-shifting and clamping analog signals in PLC I/O modules before ADC sampling.

IC Role / Device Role / Timing Role: Acts as dual-rail clamp protecting op-amp inputs from ESD or overvoltage events.

Use Value: Matched V_Z (≤5% Δ) ensures symmetrical clipping thresholds for bipolar signal integrity.

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-C6V8	Single Zener, DO-35 through-hole, 400mW, ±5% V_Z, no V_Z matching	Lacks dual-element integration; requires two devices for dual-reference use	Select when board space permits through-hole mounting and matched dual-Zener function is unnecessary
DZ23C6V2-7	Same SOT23 dual-Zener package, but 6.2V nominal (5.8–6.6V), 10Ω Z_ZT	Slightly lower voltage and higher impedance - less suitable for tight-tolerance 6.8V references	Choose only if system design tolerates 0.6V lower reference or requires different TC (+0.030%/°C)

Compared with BZX79-C6V8 and DZ23C6V2-7, DZ23C6V8-7 uniquely delivers matched dual-Zener functionality in SMT format with superior impedance (8Ω), tighter voltage range (6.4–7.2V), and optimized TC (+0.045%/°C) for precision feedback and clamping.

FAQ

What is the maximum continuous power dissipation for DZ23C6V8-7?

DZ23C6V8-7 has a rated power dissipation of 300mW when mounted on an FR4 PCB using the manufacturer-recommended pad layout. Derating is required above +25°C ambient per the published power derating curve - e.g., ~200mW at +85°C ambient. Exceeding this limit risks thermal runaway and permanent degradation of zener characteristics.

How is the common-cathode configuration used in circuit design?

The common-cathode arrangement (Pin 2) allows both Zeners to share a single reference node - ideal for generating complementary clamping voltages (e.g., +6.8V and −6.8V relative to cathode) or implementing differential voltage references. It eliminates need for external wiring between cathodes, reducing parasitic inductance and improving high-frequency transient response.

Does DZ23C6V8-7 meet automotive qualification standards?

The commercial-grade DZ23C6V8-7 is JEDEC-qualified for high reliability but not AEC-Q200 certified. For automotive use, Diodes offers the Q-suffix variant DZ23C6V8Q-7-F, which is manufactured in IATF 16949-certified facilities and qualified to AEC-Q200 - including PPAP documentation and enhanced change control.

What does the "-7-F" suffix indicate in the part number?

The "-7-F" suffix denotes tape-and-reel packaging: "-7" specifies 3000-unit reels, and "-F" indicates lead-free, RoHS-compliant finish. This packaging format is optimized for automated SMT placement equipment and ensures consistent orientation and feeding during high-volume assembly.
