Product details
Overview
DZ23C8V2-7-F from Diodes Incorporated is a dual common-cathode 300mW surface-mount Zener diode with nominal Zener voltage 8.2V (7.7–8.7V range), 7.0Ω maximum Zener impedance at 5mA, +0.055%/°C temperature coefficient, and minimum reverse voltage 6.0V at 0.1µA leakage. It enables precision voltage reference and overvoltage clamping in compact dual-rail power monitoring circuits.
For engineers reviewing the DZ23C8V2-7-F datasheet, DZ23C8V2-7-F pinout, DZ23C8V2-7-F application, or DZ23C8V2-7-F equivalent, this part supports dual-voltage regulation in space-constrained DC-DC feedback paths, rail-to-rail voltage supervision, and matched dual-reference generation where ≤5% VZ tracking between elements is required.
Technical Context
This device integrates two Zener diodes sharing a common cathode terminal in a single SOT23 package, enabling bidirectional voltage clamping or independent low-power reference generation from a shared ground node. Its matched VZ tolerance (≤5% ΔVZ) ensures consistent behavior across both elements under identical thermal conditions.
The 300mW power rating and 417°C/W junction-to-ambient thermal resistance require PCB pad layout per Diodes' recommended footprint to sustain full-rated dissipation. Operation is specified from –65°C to +150°C, with stable breakdown characteristics verified at IZT = 5mA and IZK = 1mA test currents.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage Range | 7.7V to 8.7V at IZT = 5mA - defines usable regulation window for 8.2V nominal reference |
| Zener Impedance | 7.0Ω max at IZT = 5mA - ensures minimal output voltage deviation under load transients |
| Temperature Coefficient | +0.055%/°C - quantifies positive drift of VZ with rising ambient temperature |
| Minimum Reverse Voltage | 6.0V at IR = 0.1µA - confirms reliable blocking below regulation threshold |
| Power Dissipation | 300mW - sets absolute maximum continuous DC power handling on FR4 board |
| Junction Temperature Range | –65°C to +150°C - supports operation in automotive under-hood and industrial control environments |
Pinout & Package

| Pin 3 (Anode 2) | Second Zener anode | Connects to second regulated node; enables dual independent references from one package |
Key Features
| Feature | Design Value |

Applications
| Power Supply Feedback | Dual-Rail Voltage Monitor |
|---|---|
Use Scenario: Regulating isolated DC-DC converter output via optocoupler feedback loop. IC Role / Device Role / Timing Role: Provides precise 8.2V reference for TL431-type shunt regulator input. Use Value: Matches TL431's 2.5V reference with resistor divider; dual structure allows simultaneous primary/secondary side referencing. |
Use Scenario: Monitoring ±12V rails in industrial PLC I/O modules. IC Role / Device Role / Timing Role: Clamps overvoltage on each rail using separate anodes while sharing cathode to ground. Use Value: Single-component solution replaces two discrete Zeners, reducing BOM count and layout complexity. |

FAQ
What is the maximum continuous Zener current per element in DZ23C8V2-7-F?
The device supports up to 5mA per Zener element at 25°C ambient when mounted on FR4 with Diodes' recommended pad layout. At this current, power dissipation is 41mW per element (8.2V × 5mA), well within the 300mW total package limit. Derating applies above 25°C per the published power derating curve.
Can Pin 1 and Pin 3 be used simultaneously with different load conditions?
Yes-Pin 1 (Anode 1) and Pin 3 (Anode 2) operate independently as long as their combined power dissipation does not exceed 300mW and junction temperature remains ≤150°C. The common cathode (Pin 2) must be connected to a stable reference potential, typically system ground or a bias rail.
Is DZ23C8V2-7-F suitable for use in automotive applications?
No-the -7-F suffix denotes commercial qualification. For automotive use, the Q-suffix variant DZ23C8V2-Q-7-F is required; it undergoes AEC-Q101 stress testing, is PPAP-capable, and is manufactured in IATF 16949-certified facilities with full change control and lot traceability.
How is Zener voltage matching verified between the two elements?
Matching is guaranteed by binning during final test: ΔVZ = |VZ1 − VZ2| ≤ 5% of the nominal 8.2V value (i.e., ≤0.41V difference). This is measured at IZT = 5mA on both elements under identical thermal conditions and is documented in Diodes' production test reports.
