Product details

Overview

DZ23C11-7-F from Diodes Incorporated is a dual common-cathode 300mW surface-mount Zener diode with nominal zener voltage 11V (10.4–11.6V range), ±5% matching between diodes, and 20Ω typical zener impedance at 5mA. It operates from −65°C to +150°C and is used for precision voltage reference and overvoltage protection in dual-rail power monitoring circuits.

For engineers reviewing the DZ23C11-7-F datasheet, DZ23C11-7-F pinout, DZ23C11-7-F application, or DZ23C11-7-F equivalent, key selection criteria include matched zener voltage tolerance, low thermal resistance (417°C/W), SOT23 package compatibility, and dual-diode symmetry for differential reference or redundancy schemes.

Technical Context

This device integrates two discrete Zener diodes sharing a common cathode terminal in a single SOT23 package, enabling compact dual-voltage regulation or bidirectional clamping without external interconnects. Its matched V_Z deviation ≤5% supports high-accuracy differential sensing and rail-to-rail voltage supervision.

The diodes exhibit a positive temperature coefficient of +0.070%/°C at 11V, ensuring stable regulation across industrial temperature ranges. Thermal resistance of 417°C/W is specified for FR4 PCB mounting with recommended pad layout, directly impacting maximum allowable continuous current under ambient conditions.

Key Specifications

Parameter	Value and Actual Design Meaning
Zener Voltage Range	10.4–11.6 V at I_ZT = 5 mA - defines operating regulation window for precision reference use
Max Zener Impedance	20 Ω at I_ZT = 5 mA - ensures minimal output voltage variation under load transients
Power Dissipation	300 mW - sets absolute DC current limit of ~27 mA at 11V before thermal derating
Temp Coefficient	+0.070 %/°C - enables predictable drift compensation in temperature-sensitive references
Reverse Leakage	≤0.1 µA at V_R = 8.5 V - guarantees negligible standby current in high-impedance bias networks
Thermal Resistance	417 °C/W - determines junction temperature rise per milliwatt; critical for reliability on FR4 boards
Operating Temp	−65°C to +150°C - supports deployment in automotive engine compartments and industrial control enclosures

Applications

Industrial Power Monitoring

Redundant Reference Generation

Use Scenario: Dual-rail 12V/5V power system in PLC backplane where independent overvoltage detection is required per rail.

IC Role / Device Role / Timing Role: Dual Zener provides simultaneous 11V and 5.1V clamping thresholds using matched elements to ensure coordinated shutdown timing.

Use Value: Eliminates mismatch-induced false triggers; common-cathode architecture ensures identical thermal environment for both diodes.

Use Scenario: Precision analog front-end in medical sensor module requiring fail-safe voltage reference with cross-check capability.

IC Role / Device Role / Timing Role: One Zener serves as primary 11V reference; the second acts as real-time comparator against the same node for fault detection.

Use Value: Enables in-situ self-test without additional components-detects open-circuit or degradation via leakage asymmetry.

Differential Signal Clamping

Automated Test Equipment (ATE) Biasing

Use Scenario: Protecting differential ADC inputs in motor drive feedback circuits exposed to ESD and inductive kickback.

IC Role / Device Role / Timing Role: Anodes connected to complementary signal lines; shared cathode tied to reference plane - forms symmetrical ±11V clamp.

Use Value: Maintains signal integrity during transients while preserving common-mode rejection ratio (CMRR) through matched breakdown behavior.

Use Scenario: Setting precise bias points for op-amp test fixtures in semiconductor wafer probing systems.

IC Role / Device Role / Timing Role: Provides dual 11V references for calibration sources and guard ring biasing within same thermal zone.

Use Value: Reduces thermal EMF errors between reference paths; eliminates inter-device thermal gradients affecting measurement accuracy.

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-C11,113 (Nexperia)	Single Zener, DO-35 glass package; no dual-element or matching spec	Requires two devices and external matching; unsuitable for differential or space-constrained layouts	Select only when legacy through-hole assembly or cost-driven single-channel use is mandatory
DZ23C10-7-F (Diodes Inc.)	10.4–11.6V → 9.4–10.6V range; 15Ω Z_ZT; +0.065%/°C TC	Lower nominal voltage ideal for 10V reference rails; tighter impedance but reduced headroom vs. 12V systems	Choose for 10V-based designs needing marginally better regulation stability at lower voltage

Compared with BZX79-C11 and DZ23C10-7-F, DZ23C11-7-F uniquely delivers matched dual-Zener functionality in SOT23, enabling compact differential referencing unachievable with single-diode alternatives or non-matched duals.

FAQ

What is the maximum continuous Zener current for DZ23C11-7-F at 25°C ambient?

At 25°C ambient and with recommended FR4 pad layout, the maximum continuous Zener current is approximately 27 mA, calculated from P_D = 300 mW and V_Z ≈ 11 V. Derating begins above 25°C per the 417°C/W thermal resistance curve; at 85°C ambient, max current drops to ~18 mA.

Can DZ23C11-7-F be used in automotive applications?

DZ23C11-7-F is a commercial-grade part. For automotive use, Diodes offers the Q-suffix variant DZ23C11Q-7-F, qualified to AEC-Q101, manufactured in IATF 16949 facilities, and PPAP-capable. The -7-F version lacks automotive qualification documentation and change control.

How is polarity identified on the DZ23C11-7-F SOT23 package?

Polarity is marked by a cathode band adjacent to Pin 2 (common cathode) on the top surface. Pin 1 is the leftmost terminal when the marking band is oriented at the upper-left corner; Pin 3 is rightmost. The schematic symbol shows both anodes feeding into a shared cathode node.

Is there a common-anode version of this dual Zener?

Yes - the AZ23 series (e.g., AZ23C11-7-F) provides identical dual-Zener functionality in common-anode configuration. Pinout differs: Pin 2 becomes common anode, Pins 1 and 3 serve as independent cathodes. Electrical specs and packaging are otherwise identical.
