Product details
Overview
DZ23C5V6-7 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), 40Ω maximum zener impedance at 5mA, +0.020%/°C temperature coefficient, and 1.0V minimum reverse voltage - used for precision voltage reference and overvoltage clamping in dual-rail power monitoring circuits.
For engineers reviewing the DZ23C5V6-7 datasheet, DZ23C5V6-7 pinout, DZ23C5V6-7 application, or DZ23C5V6-7 equivalent, key selection criteria include matched zener voltage tolerance (≤5% ΔVZ between diodes), SOT23 package compatibility with automated assembly, JEDEC-compliant thermal performance (RθJA = 417°C/W), and RoHS/halogen-free compliance for industrial control and automotive-grade derivative designs.
Technical Context
This dual Zener operates in common-cathode configuration: Pins 1 and 3 are anodes, Pin 2 is shared cathode. Each diode delivers stable regulation at IZT = 5.0mA with typical VZ = 5.6V and low dynamic impedance (ZZT ≤ 40Ω).
It exhibits a positive temperature coefficient (+0.020%/°C), enabling predictable drift compensation in bias networks. Thermal derating begins above 25°C ambient, with full 300mW dissipation only at TA ≤ 50°C per the published power derating curve.
Key Specifications

|---|---|
| Zener Voltage Range | 5.2–6.0 V at IZT = 5.0 mA - ensures tight regulation window for dual-supply reference generation |
| Zener Impedance | ≤40 Ω at IZT = 5.0 mA - minimizes output voltage variation under load transients |
| Temperature Coefficient | +0.020 %/°C - enables predictable, low-drift biasing in temperature-varying environments |
| Power Dissipation | 300 mW - supports continuous operation in compact SOT23 footprint with defined PCB pad layout |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-Zener reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX79C5V6 (Nexperia) | Single Zener, DO-35 through-hole; no dual configuration or VZ matching | Requires two devices and board space for matching; lacks SOT23 automation support | Select only if through-hole assembly is mandatory and dual-diode matching is not required |
| DZ23C5V6-7-F (Diodes Inc.) | Same die, identical specs; "-F" suffix denotes halogen-free plating (vs. standard "-7") | No functional difference; "-F" variant meets stricter environmental compliance (Br+Cl <1500ppm) | Choose "-F" for medical or green-certified programs requiring halogen-free declarations |
Compared with BZX79C5V6 and DZ23C5V6-7-F, the DZ23C5V6-7 uniquely delivers matched dual-Zener functionality in SOT23 with JEDEC reliability - eliminating discrete matching effort while supporting automated production and extended temperature stability.

FAQ
What is the maximum continuous power dissipation for DZ23C5V6-7 at 75°C ambient?
At 75°C ambient, the device must be derated per the published power derating curve: starting from 300mW at 50°C, it drops linearly to 0mW at 150°C. At 75°C, allowable dissipation is 250mW. This assumes mounting on FR4 with Diodes' recommended pad layout (2.0 × 0.8 mm copper area per pad).
Can DZ23C5V6-7 be used as a single Zener by leaving one anode unconnected?
Yes - Pin 1 or Pin 3 may be left floating or unused without affecting the other diode's regulation performance. However, the unused anode must not be shorted or biased, as that could forward-bias the junction and alter thermal behavior or leakage. The common cathode (Pin 2) remains essential for either configuration.
Is DZ23C5V6-7 qualified for automotive applications?
No - DZ23C5V6-7 is commercial-grade. For automotive use, Diodes offers the Q-suffix variant DZ23C5V6Q-7-F, which is AEC-Q200 qualified, PPAP-capable, and manufactured in IATF 16949 certified facilities. The "Q" part undergoes additional stress testing and change control per automotive requirements.
What does the "-7" suffix indicate in DZ23C5V6-7?
The "-7" suffix denotes tape-and-reel packaging: 3000 units per reel in SOT23 carrier tape, compatible with standard pick-and-place equipment. It also indicates commercial temperature grade (–65°C to +150°C) and standard lead-free plating (matte tin over Alloy 42). The "-F" variant adds halogen-free compound compliance.
