Diodes Incorporated DZ23C7V5-7

Overview

DZ23C7V5-7 from Diodes Incorporated is a dual common-cathode 300mW surface-mount Zener diode with nominal zener voltage 7.5V (7.0–7.9V range), maximum zener impedance 7.0Ω at 5mA, and positive temperature coefficient +0.050%/°C - used for precision voltage reference and overvoltage protection in low-power analog signal conditioning circuits.

For engineers reviewing the DZ23C7V5-7 datasheet, DZ23C7V5-7 pinout, DZ23C7V5-7 application, or DZ23C7V5-7 equivalent, key selection criteria include matched dual-zener tracking (≤5% ΔV_Z), SOT23 package compatibility with automated assembly, and stable regulation under 5mA test current with minimal thermal drift.

Technical Context

This dual-Zener device integrates two independent zener elements sharing a common cathode terminal, enabling differential or complementary reference generation in compact space-constrained designs. Its matched V_Z tolerance (≤5% difference between diodes) supports high-accuracy biasing and clamping without external trimming.

The device operates within -65°C to +150°C ambient range and exhibits a defined +0.050%/°C temperature coefficient at 7.5V, ensuring predictable voltage shift across industrial temperature gradients. Thermal resistance R_θJA is 417°C/W on FR4 PCB with recommended pad layout.

FAQ

What is the maximum continuous power dissipation for DZ23C7V5-7?

The DZ23C7V5-7 has a rated power dissipation of 300 mW when mounted on an FR4 PCB with the recommended pad layout per Diodes Incorporated's package outline documentation. Derating is required above +25°C ambient, following the linear curve in Figure 1 of DS18002 Rev. 22-2, reaching zero power at +150°C junction temperature.

How are the two zener elements configured internally?

The DZ23C7V5-7 integrates two independent zener diodes sharing a single cathode terminal (Pin 2), with separate anodes on Pin 1 and Pin 3. This common-cathode arrangement allows both diodes to regulate or clamp relative to the same reference potential, enabling matched performance without external connection complexity.

Is DZ23C7V5-7 suitable for automotive applications?

The commercial-grade DZ23C7V5-7 is not qualified to AEC-Q101. For automotive use, Diodes Incorporated offers the Q-suffix variant DZ23C7V5Q-7-F, which is manufactured in IATF 16949-certified facilities and qualified to AEC-Q101 standards with PPAP documentation support.

What does the "-7" suffix indicate in the part number?

The "-7" suffix denotes tape-and-reel packaging in 3,000-unit reels, compatible with standard SMT pick-and-place equipment. It follows Diodes Incorporated's standard ordering convention where "-7-F" indicates RoHS-compliant, lead-free, green molding compound packaging - confirmed in the Ordering Information section of DS18002.
