Product details

Overview

DZ23C36-7-F from Diodes Incorporated is a dual common-cathode 300mW surface-mount Zener diode pair with nominal zener voltage 36V (34–38V range), maximum zener impedance 90Ω at 5mA, and temperature coefficient +0.090%/°C - used for precision voltage reference and overvoltage clamping in power supply feedback loops and analog sensor signal conditioning.

For engineers reviewing the DZ23C36-7-F datasheet, DZ23C36-7-F pinout, DZ23C36-7-F application, or DZ23C36-7-F equivalent, key selection criteria include matched dual-zener tracking (≤5% ΔV_Z), SOT23 package compatibility with automated assembly, JEDEC-qualified reliability, and low-temperature-coefficient stability across -65°C to +150°C operation.

Technical Context

This dual-Zener device integrates two independent zener elements sharing a common cathode terminal, enabling compact voltage referencing or bidirectional clamping without external node routing. Its matched V_Z tolerance (≤5% difference between diodes) supports differential sensing and rail-to-rail clamp symmetry.

Designed for high-reliability commercial applications, it meets JEDEC standards for thermal performance (R_θJA = 417°C/W on FR4) and operates across -65°C to +150°C ambient, with reverse leakage limited to 0.1µA at 27V minimum reverse voltage.

Key Specifications

Parameter	Value and Actual Design Meaning
Zener Voltage Range	34 V to 38 V - defines usable regulation window under 5 mA test current; enables stable 36 V reference with ±5.6% tolerance.
Power Dissipation	300 mW - maximum continuous DC power handling at T_A = 25°C; derates linearly above 25°C per 417°C/W thermal resistance.
Zener Impedance	90 Ω @ I_ZT = 5 mA - indicates dynamic resistance during regulation; lower values improve load regulation and ripple rejection.
Temperature Coefficient	+0.090 %/°C - quantifies V_Z drift with temperature; positive sign means voltage increases with heating, critical for thermal stability design.
Minimum Reverse Voltage	27.0 V @ I_R = 0.1 µA - specifies knee of reverse breakdown curve; ensures reliable conduction onset before full zener action.
ΔV_Z Matching	≤ 5% - guaranteed maximum voltage difference between the two internal zeners; enables matched reference pairs in differential circuits.

Pinout & Package

Package: SOT23 - ultra-small surface-mount plastic package (2.90 mm × 2.40 mm × 1.15 mm), RoHS-compliant, halogen-free, moisture sensitivity level 1.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1 (Anode 1)	First Zener Anode	Connects to first zener junction; reverse-biased to achieve 36 V breakdown relative to common cathode.
Pin 2 (Cathode)	Common Cathode	Shared cathode node for both zeners; serves as reference output or clamp return path.
Pin 3 (Anode 2)	Second Zener Anode	Connects to second zener junction; enables dual-voltage reference or symmetrical clamping topology.

Key Features

Feature	Design Value
Dual Zener in Common Cathode	Enables compact dual-reference generation or bidirectional transient suppression without discrete interconnects.
Matched V_Z Tracking	≤5% ΔV_Z ensures consistent voltage offset between channels - critical for ratiometric sensor interfaces.
JEDEC High-Reliability Qualification	Validated per AEC-Q stress protocols for extended lifetime in industrial environments (-65°C to +150°C).
SOT23 Automated Assembly Compatibility	Standard footprint and matte tin terminations support high-yield reflow and wave soldering per MIL-STD-202.

Applications

Switch-Mode Power Supply Feedback

Industrial Sensor Signal Conditioning

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

IC Role / Device Role / Timing Role: Dual zener provides precise 36 V reference at secondary-side error amplifier input while clamping transient spikes.

Use Value: Tight V_Z matching ensures stable regulation setpoint; low Z_ZT minimizes feedback loop error under load transients.

Use Scenario: Protecting 24 V analog inputs of PLC modules from ESD and surge events.

IC Role / Device Role / Timing Role: Common-cathode configuration enables bidirectional clamping between signal line and 24 V rail.

Use Value: Dual 36 V zeners clamp both positive and negative excursions symmetrically, preserving signal integrity below ±30 V.

Automotive Body Control Module Reference

Medical Instrumentation Voltage Calibration

Use Scenario: Providing stable reference for ADC biasing in 12 V vehicle subsystems with wide ambient temperature swings.

IC Role / Device Role / Timing Role: One zener supplies reference to ADC driver; second serves as backup or diagnostic comparator threshold.

Use Value: +0.090%/°C TC allows predictable drift compensation; JEDEC qualification ensures operation at 125°C junction temperature.

Use Scenario: Calibrating 30–40 V high-precision DAC outputs in portable diagnostic equipment.

IC Role / Device Role / Timing Role: Dual zener acts as traceable voltage standard during factory calibration and field verification.

Use Value: Matched V_Z enables cross-channel validation; low leakage (<0.1 µA) prevents loading errors in high-impedance calibration paths.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
BZX384-C36,115 (Nexperia)	Single 36 V Zener in SOD323; no dual-element or V_Z matching spec.	Requires two devices for dual-reference use; lacks common-cathode integration.	Select when board space permits discrete placement and matched tracking is not required.
DZ23C36-7 (Diodes Inc., non-F variant)	Identical electrical specs but lead-free plating not explicitly certified per RoHS 3 (2015/863/EU).	Not suitable for new designs targeting full halogen/antimony compliance.	Choose DZ23C36-7-F for green-compliant production; avoid DZ23C36-7 where Br+Cl <1500 ppm is mandated.

Compared with BZX384-C36,115 and DZ23C36-7, the DZ23C36-7-F uniquely delivers matched dual-zener functionality in one SOT23 footprint with verified halogen/antimony-free compliance - essential for space-constrained, high-reliability, and environmentally regulated designs.

FAQ

What is the maximum continuous power dissipation for DZ23C36-7-F at 70°C ambient?

At 70°C ambient, derating begins at 25°C using R_θJA = 417°C/W. The allowable temperature rise is 70 − 25 = 45°C, so power must be reduced to 300 mW × (1 − 45/417) ≈ 268 mW. This ensures junction temperature remains within the -65°C to +150°C rating.

Can DZ23C36-7-F be used for bidirectional ESD protection on a 24 V data line?

Yes - its common-cathode dual-zener structure allows connection between signal and 24 V rail, clamping positive transients to ~36 V above rail and negative transients to ~36 V below ground. With 27 V minimum reverse voltage, it avoids premature conduction during normal 24 V operation.

Is the 5% ΔV_Z matching guaranteed across temperature or only at 25°C?

The ≤5% ΔV_Z specification applies at T_A = 25°C per the datasheet's Electrical Characteristics table. While both diodes track similarly over temperature due to monolithic integration, the 5% limit is not guaranteed across the full -65°C to +150°C range - system-level testing is recommended for critical tracking applications.

Does DZ23C36-7-F meet AEC-Q200 for passive components?

No - DZ23C36-7-F is qualified to JEDEC standards for high reliability but is not AEC-Q200-certified. For automotive applications requiring AEC-Q200, Diodes offers Q-suffix variants (e.g., DZ23C36Q-7-F) manufactured in IATF 16949 facilities and PPAP-capable.
