Product details

Overview

AZ23C5V6-7-F from Diodes Incorporated is a dual common-anode Zener diode in SOT23 package, rated for 300 mW total power dissipation, with nominal Zener voltage 5.6 V (5.2–6.0 V range), ±5% matching between diodes, and +0.020 %/°C temperature coefficient. It provides precision voltage reference and overvoltage clamping in compact dual-diode configuration for space-constrained power rail protection circuits.

For engineers reviewing the AZ23C5V6-7-F datasheet, AZ23C5V6-7-F pinout, AZ23C5V6-7-F application, or AZ23C5V6-7-F equivalent, this part supports dual-rail stabilization, low-power voltage regulation, and matched-clamp design where tight V_Z tracking and thermal stability are required.

Technical Context

This device integrates two Zener diodes sharing a common anode terminal, enabling bidirectional clamping or independent reference generation from a single anode node. Its 40 Ω maximum Zener impedance at 5 mA and 400 Ω at 1 mA ensure stable regulation under light-to-moderate load conditions.

The +0.020 %/°C temperature coefficient and ≤5% inter-diode V_Z variation support matched performance across temperature in dual-reference or differential clamp applications, while its JEDEC-qualified construction ensures reliability in commercial and automotive-derivative designs.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
BZX84-C5V6LT1G	Single Zener in SOT23; no dual configuration or V_Z matching spec.	Requires two devices and external matching verification for dual-rail use.	Select when only one reference rail is needed or board area permits discrete duplication.
DZ23C5V6-7-F	Common-cathode dual Zener; complementary polarity to AZ23 series.	Suitable for high-side clamp or positive-rail referencing where cathode-common topology aligns with system grounding.	Choose when circuit requires cathode-referenced clamping or matches existing DZ23-series BOMs.

Compared with BZX84-C5V6LT1G and DZ23C5V6-7-F, AZ23C5V6-7-F uniquely delivers factory-matched dual Zeners in common-anode configuration-reducing layout complexity, eliminating manual matching, and enabling true differential reference stability without added components.

FAQ

What is the maximum continuous power dissipation per Zener in AZ23C5V6-7-F?

The device has a total 300 mW power rating shared between both Zeners. Under uniform thermal conditions and equal current distribution, each Zener may dissipate up to 150 mW continuously. Derating applies above +70°C ambient per the published power derating curve, reaching zero dissipation at +150°C.

Can AZ23C5V6-7-F be used in automotive applications?

Yes - the AZ23C5V6-7-F is qualified to AEC-Q101 standards (HBM 8 kV, MM 400 V) and meets IEC 61000-4-2 ESD requirements. For full automotive qualification including PPAP and IATF 16949 manufacturing, the Q-suffix variant (AZ23C5V6Q-7-F) must be selected per Diodes' automotive product listing.

How is the 5% ΔV_Z matching verified between the two Zeners?

The ≤5% V_Z variation is measured at I_ZT = 5 mA during final test screening per DS18003 Rev. 18-2. Each unit undergoes binning to ensure both diodes fall within the same 5.2–6.0 V specification band, with matching confirmed on wafer-level and final test.

Is there a recommended pad layout for SOT23 mounting of AZ23C5V6-7-F?

Yes - Diodes specifies a recommended SOT23 pad layout with dimensions C = 2.0 mm, X = 0.8 mm, X1 = 1.35 mm, Y = 0.9 mm, and Y1 = 2.9 mm (all in mm). This layout ensures optimal thermal conduction, solder joint reliability, and compliance with IPC-7351B standards for SOT23 footprint.
