Diodes Incorporated DZ23C15-7-F

Overview

DZ23C15-7-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 typical temperature coefficient of +0.080%/°C. It provides precision voltage reference and overvoltage clamping in space-constrained power management circuits.

For engineers reviewing the DZ23C15-7-F datasheet, DZ23C15-7-F pinout, DZ23C15-7-F application, or DZ23C15-7-F equivalent, this page delivers verified electrical specs, thermal derating behavior, SOT23 terminal mapping, and validated alternatives for dual-zener reference design.

Technical Context

This device integrates two matched 15V Zener diodes sharing a common cathode terminal, enabling bidirectional voltage regulation or differential reference generation. Its 300mW power rating applies to the combined dissipation across both diodes under DC or low-duty-cycle pulse conditions.

The ±5% V_Z matching ensures tight tracking between channels at I_ZT = 5.0mA, while the +0.080%/°C temperature coefficient supports stable operation from –65°C to +150°C ambient, with thermal resistance R_θJA = 417°C/W on FR4 PCB.

FAQ

What is the maximum continuous power dissipation for DZ23C15-7-F?

The device is rated for 300mW total power dissipation across both Zener diodes under DC conditions on FR4 PCB with recommended pad layout. Derating begins above 25°C ambient per Figure 1, reaching zero dissipation at 150°C junction temperature.

How is the common cathode configured electrically in DZ23C15-7-F?

Pin 2 is the common cathode node; Pins 1 and 3 are independent anodes. When Pin 2 is biased positive relative to either anode, that Zener conducts in reverse breakdown-enabling independent or complementary clamping paths.

Does DZ23C15-7-F meet AEC-Q200 requirements?

No-DZ23C15-7-F is commercial-grade. For automotive applications, Diodes offers the Q-suffix variant (e.g., DZ23C15Q-7-F), qualified to AEC-Q200, PPAP-capable, and manufactured in IATF 16949-certified facilities.

Can DZ23C15-7-F replace single-Zener diodes in existing designs?

Yes-if the circuit uses two separate 15V Zeners sharing a common cathode node. The SOT23 footprint and pinout match standard dual-Zener layouts; however, verify thermal margin since 300mW is shared between both devices, not per diode.
