Product details

Overview

DZ23C15Q-7-F from Diodes Incorporated is a dual common-cathode 15V Zener diode pair in SOT23 package, rated for 300mW total power dissipation, with ±5% matching between zener voltages and 13.8–15.6V nominal breakdown range at 5mA test current. It serves precision voltage reference and dual-rail clamping in low-power analog signal conditioning circuits.

For engineers reviewing the DZ23C15Q-7-F datasheet, DZ23C15Q-7-F pinout, DZ23C15Q-7-F application, or DZ23C15Q-7-F equivalent, key selection criteria include matched zener voltage tolerance, thermal resistance (417°C/W), JEDEC-qualified reliability, SOT23 footprint compatibility, and automotive-grade qualification status (Q-suffix).

Technical Context

This dual zener operates in common-cathode configuration, enabling independent anode control for bidirectional voltage regulation or differential reference generation. Each diode exhibits a typical temperature coefficient of +0.080%/°C and maintains ≤5% inter-device V_Z mismatch under identical bias conditions.

Designed for surface-mount automated assembly, it delivers stable 15V regulation across -65°C to +150°C operating range with 300mW total power rating and 110Ω maximum zener impedance at 5mA (ZZT) and 110Ω at 1mA (ZZK).

Key Specifications

Parameter	Value and Actual Design Meaning
Zener Voltage Range	13.8–15.6V at I_ZT = 5mA - defines usable regulation window for precision reference design
Power Dissipation	300mW - limits continuous current to ~20mA at 15V without heatsinking
Zener Impedance	30Ω (ZZT @ 5mA), 110Ω (ZZK @ 1mA) - determines regulation stiffness under load transients
Temperature Coefficient	+0.080%/°C - enables predictable drift compensation in temperature-sensitive references
Thermal Resistance	417°C/W - requires careful PCB copper area planning for thermal management
Reverse Voltage	11.0V minimum @ I_R = 0.1µA - ensures reliable turn-on threshold before breakdown

Pinout & Package

Package: SOT23 - 3-pin plastic surface-mount package with matte tin-plated alloy 42 lead frame, UL 94V-0 rated molding compound, and moisture sensitivity level 1.

Pin/Terminal	Circuit Role	Design Meaning

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-C15 (ON Semiconductor)	Single 15V zener in DO-35; no dual or matched configuration	Requires two discrete devices and external matching for dual-rail use	Select when board space permits discrete implementation and V_Z matching is managed externally
DZ23C15-7-F (Diodes Inc., non-Q)	Identical electrical specs but commercial-grade qualification (non-AEC-Q200)	Lacks PPAP documentation and IATF 16949 traceability required for automotive production	Select for cost-sensitive industrial prototypes where automotive change control is not mandated

Compared with BZX79-C15 and DZ23C15-7-F, DZ23C15Q-7-F uniquely integrates matched dual 15V zeners in one SOT23 footprint with automotive-grade process controls-reducing component count, eliminating manual matching, and ensuring supply chain compliance for Tier-1 automotive programs.

FAQ

What does the 'Q' suffix in DZ23C15Q-7-F signify?

The 'Q' suffix indicates automotive-grade qualification per AEC-Q200 stress testing standards, including extended temperature operation (-65°C to +150°C), PPAP documentation readiness, and manufacturing in IATF 16949-certified facilities. It is not present in commercial variants like DZ23C15-7-F.

Can DZ23C15Q-7-F be used as a single 15V zener by leaving one anode unconnected?

Yes - Pin 1 or Pin 3 may be left floating while using the other anode with the common cathode (Pin 2) as a standard 15V zener. However, doing so forfeits the matched-pair advantage and does not reduce power rating; total dissipation remains limited to 300mW across both junctions.

Is the 5% V_Z matching guaranteed over temperature?

No - the ≤5% V_Z matching specification applies only at T_A = +25°C per the datasheet's Electrical Characteristics table. Temperature-induced drift may cause divergence; actual mismatch at extremes should be verified using the +0.080%/°C TC and derating curves.

Does DZ23C15Q-7-F support reflow soldering per J-STD-020?

Yes - it is rated for moisture sensitivity level 1 (MSL-1), meaning unlimited floor life and full compatibility with standard Pb-free reflow profiles up to 260°C peak, as confirmed by Diodes' qualified process and JEDEC-compliant thermal characterization.
