Diodes Incorporated DZ23C6V8-7-F

Overview

DZ23C6V8-7-F from Diodes Incorporated is a dual common-cathode 300mW surface-mount Zener diode with nominal zener voltage 6.8V (6.4–7.2V range), 8.0Ω max zener impedance at 5mA, +0.045%/°C temperature coefficient, and 3.0V minimum reverse voltage at 0.1µA leakage. It serves precision voltage reference and overvoltage protection in low-power analog signal conditioning circuits.

For engineers reviewing the DZ23C6V8-7-F datasheet, DZ23C6V8-7-F pinout, DZ23C6V8-7-F application, or DZ23C6V8-7-F equivalent, key selection criteria include matched dual-zener tracking (≤5% ΔV_Z), SOT23 package compatibility with automated assembly, thermal resistance of 417°C/W on FR4, and JEDEC-qualified reliability for industrial-grade designs.

Technical Context

This dual-Zener device integrates two independent zener elements sharing a common cathode terminal, enabling compact voltage referencing or bidirectional clamping in space-constrained layouts. Its matched V_Z tolerance ensures consistent regulation across both diodes under identical bias conditions.

The device operates within –65°C to +150°C ambient temperature range and derates linearly above 25°C per the published power curve. Its low 8.0Ω dynamic impedance at I_ZT = 5mA supports stable regulation under moderate load transients.

FAQ

What is the maximum continuous power dissipation for DZ23C6V8-7-F on a standard FR4 PCB?

The device is rated for 300mW continuous power dissipation when mounted on an FR4 printed circuit board using the recommended pad layout. This rating assumes ambient temperature of 25°C and derates linearly above that point, reaching zero dissipation at approximately 145°C ambient due to its 417°C/W thermal resistance.

How is the common-cathode configuration used in practical circuit design?

In practice, the common cathode (Pin 2) is tied to the regulated voltage node or ground, while Pins 1 and 3 serve as independent anodes. This allows either dual independent references (e.g., 6.8V and another value via external resistor), bidirectional clamping (e.g., USB D+/D−), or temperature-compensated bias networks using both zeners' matched characteristics.

Does DZ23C6V8-7-F meet automotive qualification standards?

No - DZ23C6V8-7-F is a commercial-grade part qualified to JEDEC standards for high reliability. For automotive use, Diodes offers the Q-suffix variant DZ23C6V8Q-7-F, which is AEC-Q101 qualified, PPAP-capable, and manufactured in IATF 16949 certified facilities.

What is the significance of the "≤5% ΔV_Z" specification?

This specification guarantees that the absolute difference between the zener voltages of the two integrated diodes remains within 5% of their nominal value (6.8V) when measured under identical test conditions. It enables accurate ratiometric measurements, differential references, and matched clamping thresholds without requiring binning or external trimming.
