Diodes Incorporated DZ23C5V6-7-F

Overview

DZ23C5V6-7-F from Diodes Incorporated is a dual common-cathode 300mW surface-mount Zener diode pair with nominal zener voltage 5.6V (5.2–6.0V range), ±5% matching between diodes, +0.020%/°C temperature coefficient, and 40Ω dynamic impedance at 5mA test current. It serves as precision voltage reference and overvoltage clamp in dual-rail power monitoring circuits.

For engineers reviewing the DZ23C5V6-7-F datasheet, DZ23C5V6-7-F pinout, DZ23C5V6-7-F application, or DZ23C5V6-7-F equivalent, key selection criteria include matched dual-zener tolerance, low thermal drift, SOT23 footprint compatibility, and JEDEC-qualified reliability for industrial power management designs.

Technical Context

This device integrates two Zener diodes sharing a common cathode terminal in a single SOT23 package, enabling bidirectional clamping or complementary reference generation without external interconnects. Its matched V_Z deviation ≤5% ensures balanced regulation across dual supply rails.

The +0.020%/°C temperature coefficient minimizes drift in mid-voltage references, while 40Ω Zener impedance at I_ZT = 5mA supports stable regulation under moderate load transients. Thermal resistance R_θJA = 417°C/W reflects FR4 board mounting per Diodes' recommended pad layout.

FAQ

What is the maximum continuous Zener current for DZ23C5V6-7-F at 25°C?

At 25°C ambient, the maximum continuous Zener current is 53.6 mA, calculated from P_D = 300 mW and V_Z = 5.6 V. Derating begins at 0.72 mW/°C above 25°C per the power derating curve in DS18002 Rev. 22–2, limiting usable current at 85°C to approximately 35 mA.

Can DZ23C5V6-7-F be used for bidirectional ESD clamping on a single data line?

Yes - connect Pin 1 (Anode A) to the data line, Pin 2 (Cathode) to V_CC, and Pin 3 (Anode B) to GND. This configures one Zener as a forward clamp to V_CC + 5.6V and the other as a reverse clamp to GND − 5.6V, providing symmetrical ±5.6V transient protection relative to the rail.

Is the 5% V_Z matching guaranteed across temperature or only at 25°C?

The ≤5% ΔV_Z specification applies at T_A = +25°C per the Electrical Characteristics table. While both diodes track similarly with temperature due to monolithic integration, the datasheet does not guarantee matching across the full –65°C to +150°C operating range; design margins should assume worst-case mismatch increases outside 25°C.

Does DZ23C5V6-7-F meet AEC-Q200 requirements for passive components?

No - DZ23C5V6-7-F is qualified to JEDEC standards for high reliability but is not AEC-Q200 certified. For automotive applications, Diodes offers the Q-suffix variant DZ23C5V6Q-7-F, which undergoes additional stress testing and is manufactured in IATF 16949-certified facilities per their automotive product listing.
