Product details

Overview

DZ23C11-7 from Diodes Incorporated is a dual common-cathode 300mW surface-mount Zener diode with nominal zener voltage 11.0V (10.4–11.6V range), maximum zener impedance 20Ω at 5mA, and temperature coefficient +0.070%/°C - used for precision voltage reference and overvoltage protection in low-power analog sensor signal conditioning circuits.

For engineers reviewing the DZ23C11-7 datasheet, DZ23C11-7 pinout, DZ23C11-7 application, or DZ23C11-7 equivalent, key selection criteria include matched dual-zener tracking (≤5% ΔV_Z), SOT23 package compatibility with automated assembly, and thermal derating behavior up to +150°C ambient.

Technical Context

This dual-Zener device integrates two independent zener elements sharing a common cathode terminal, enabling bidirectional clamping or dual-reference generation in compact space-constrained designs. Its matched V_Z tolerance supports differential reference stability critical in instrumentation front-ends.

The device operates within -65°C to +150°C junction temperature range and exhibits predictable thermal drift (+0.070%/°C) and low dynamic impedance (20Ω @ 5mA), supporting stable regulation under varying load and temperature conditions without external compensation.

Key Specifications

Parameter	Value and Actual Design Meaning
Zener Voltage Range	10.4–11.6V at I_ZT = 5mA - defines usable regulation window for 11V reference design
Max Zener Impedance	20Ω @ 5mA - ensures minimal output voltage variation under load transients
Power Dissipation	300mW - sets maximum continuous DC power handling on FR4 PCB with standard pad layout
Temp Coefficient	+0.070%/°C - quantifies positive drift per degree, enabling accurate thermal error budgeting
Min Reverse Voltage	8.5V @ I_R = 0.1µA - confirms reliable turn-on threshold before breakdown conduction
Junction Temp Range	-65°C to +150°C - validates suitability for extended industrial and automotive under-hood environments

Pinout & Package

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

Pin/Terminal	Circuit Role	Design Meaning
Pin 1 (Anode 1)	First Zener Anode	Connects to first zener element; reverse-biased to generate 11V reference
Pin 2 (Cathode)	Common Cathode	Shared cathode node for both zeners; ties to regulated voltage rail or ground reference
Pin 3 (Anode 2)	Second Zener Anode	Connects to second zener element; enables dual-reference or symmetrical clamping topology

Key Features

Feature	Design Value
Dual Zeners, Common Cathode	Enables single-package dual-voltage reference or bidirectional transient suppression without discrete pairing

Applications

Industrial Sensor Signal Conditioning

Low-Power Microcontroller Voltage Reference

Use Scenario: Stabilizing excitation voltage for bridge-based pressure sensors in factory automation PLC modules.

IC Role / Device Role / Timing Role: Dual-Zener provides matched 11V reference for ADC driver stage and internal LDO feedback divider.

Use Value: ≤5% inter-zener V_Z mismatch minimizes gain error across sensor channels without per-channel trimming.

Use Scenario: Supplying precise 11V reference to SAR ADC in battery-powered environmental monitoring nodes.

IC Role / Device Role / Timing Role: Zener acts as shunt regulator for ADC reference input, replacing higher-quiescent LDOs to extend battery life.

Use Value: 300mW rating and 20Ω impedance enable stable 11V reference at <100µA load current with <10mV droop.

USB-C ESD Protection Clamp

Automotive Body Control Module Power Rail Clamp

Use Scenario: Bidirectional clamping of USB-C CC line against ±15kV contact ESD per IEC 61000-4-2.

IC Role / Device Role / Timing Role: Dual-anode/common-cathode configuration forms symmetrical clamp between CC and ground.

Use Value: Matched 11V breakdown ensures equal clamping threshold for positive and negative transients, reducing signal distortion.

Use Scenario: Overvoltage protection on 12V accessory rail in BCM during load-dump events (ISO 7637-2 Pulse 5a).

IC Role / Device Role / Timing Role: Zener conducts excess energy into chassis ground when rail exceeds 11.6V, limiting downstream IC stress.

Use Value: 150°C max operating temperature and 300mW dissipation support short-duration 120V/100ms pulses without thermal runaway.

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-C11 (Nexperia)	Single 11V Zener in DO-35; no dual-element or common-cathode topology	Requires two discrete devices and board area for dual-reference; lacks matched V_Z tracking	Select only if SOT23 footprint is not required and board space permits discrete pairing
AZ23C11-7 (Diodes Inc.)	Same dual-Zener die in common-anode configuration (Pin 1 = cathode 1, Pin 2 = anode, Pin 3 = cathode 2)	Requires inverted PCB layout and different biasing network; unsuitable for common-cathode reference topologies	Choose only when circuit architecture mandates common-anode connection (e.g., shared anode to supply rail)

Compared with BZX79-C11 and AZ23C11-7, DZ23C11-7 uniquely delivers matched dual-zener performance in a common-cathode SOT23 package - essential for space-constrained, high-accuracy dual-reference or symmetrical clamping where pinout and matching are non-negotiable.

FAQ

What is the maximum continuous reverse current the DZ23C11-7 can sustain without degradation?

The device is rated for 300mW total power dissipation. At its nominal 11V zener voltage, this corresponds to a maximum continuous reverse current of approximately 27.3mA (300mW ÷ 11V). Exceeding this value risks thermal runaway unless board-level thermal management (e.g., copper pour, airflow) is implemented per Diodes' recommended pad layout.

Does DZ23C11-7 meet AEC-Q200 stress testing requirements for passive components?

No - DZ23C11-7 is a commercial-grade part qualified to JEDEC standards but not AEC-Q200. For automotive applications, Diodes offers the Q-suffix variant DZ23C11Q-7-F, which undergoes AEC-Q200 qualification, PPAP documentation, and is manufactured in IATF 16949-certified facilities.

Can DZ23C11-7 be used in series or parallel configurations with other Zeners?

Parallel use is not recommended due to V_Z mismatch causing current hogging. Series connection is electrically permissible but increases total impedance and thermal coupling risk; Diodes specifies only single-device operation in the DS18002 datasheet, and no derating guidance is provided for multi-device stacks.

How does the +0.070%/°C temperature coefficient impact accuracy over a -40°C to +85°C operating range?

Over that 125°C span, the zener voltage shifts by +8.75mV/°C × 125°C = +1.09V - resulting in ~10% deviation from nominal 11V. For precision applications, this drift must be compensated via calibration or paired with temperature-sensing circuitry; the coefficient is specified at 25°C and remains linear within datasheet limits.
