Product details
Overview
AZ23C10W-7-F from Diodes Incorporated is a 10 V, 200 mW dual-anode Zener diode in SOT-323 package, rated for 5 mA test current with 9.4–10.6 V tolerance, 15 Ω dynamic impedance, and 0.2 μA reverse leakage at 7.6 V, used for precision voltage reference and transient suppression in low-power sensor interfaces.
For engineers reviewing the AZ23C10W-7-F datasheet, AZ23C10W-7-F pinout, AZ23C10W-7-F application, or AZ23C10W-7-F equivalent, key selection criteria include Zener voltage accuracy, thermal resistance (625 °C/W), ESD robustness (IEC 61000-4-2 contact 8 kV), RoHS compliance, and SOT-323 footprint compatibility in space-constrained PCB layouts.
Technical Context
This dual-anode Zener diode operates in reverse breakdown with tightly controlled voltage regulation across 5–20 mA Zener current range. Its 15 Ω Zener impedance at 5 mA ensures stable reference performance under varying load conditions.
Designed for ambient temperatures from –65 °C to +150 °C, it features 625 °C/W junction-to-ambient thermal resistance on FR4 board, and meets AEC-Q101 qualification with 8 kV HBM ESD rating and IEC 61000-4-2 level 4 immunity (15 kV air, 8 kV contact).
Key Specifications

|---|---|
| Zener Voltage @ 5 mA | 10 V nominal, 9.4–10.6 V min/max - defines precision reference window for analog sensing circuits |

| Zener Impedance | 15 Ω @ 5 mA - ensures <±20 mV output shift per 300 μA load change in feedback networks |
| Reverse Leakage | 0.2 μA @ 7.6 V - enables ultra-low quiescent current in battery-backed voltage monitors |
| Thermal Resistance | 625 °C/W - requires thermal pad design for >100 mW sustained dissipation in industrial environments |
| ESD Rating | 8 kV contact per IEC 61000-4-2 - protects I/O lines against human-body model discharge events |
| Operating Temp | –65 °C to +150 °C - supports automotive under-hood and industrial motor-control applications |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage reference and transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C10LT1G | Same 10 V nominal, but 400 mW rating and 30 Ω Zz @ 5 mA; SOT-23 package | Larger footprint; higher power handling but lower regulation precision | Select when >200 mW surge energy absorption is required and board area permits SOT-23 |
| MMSZ5240B-7-F | 10 V nominal, 500 mW, 17 Ω Zz @ 20 mA; SOD-123 package | Single-anode configuration; higher test current shifts regulation point | Choose for cost-sensitive industrial designs where dual-anode functionality is unnecessary |
Compared with BZX84-C10LT1G and MMSZ5240B-7-F, AZ23C10W-7-F uniquely offers dual-anode topology in SOT-323 for space-constrained bidirectional clamping, tighter 15 Ω impedance at 5 mA, and AEC-Q101 qualification-making it optimal for automotive and portable medical signal conditioning.

FAQ
What is the maximum reverse voltage this Zener can withstand before breakdown?
The AZ23C10W-7-F exhibits sharp Zener breakdown starting at 9.4 V (minimum specified Zener voltage at 5 mA). It is not rated for sustained reverse operation below this threshold; operation above 10.6 V risks exceeding power limits unless current is strictly limited by external series resistance.
Can this device be used for bidirectional ESD protection?
Yes - its dual-anode configuration allows symmetric clamping between signal and ground. When the cathode is connected to the protected line and both anodes grounded, it clamps positive transients to ~10.6 V and negative transients to ~–0.9 V (forward VF), meeting IEC 61000-4-2 Level 4 requirements.
Is thermal derating required for operation above 25°C ambient?
Yes - power dissipation must be linearly derated above 25°C using the 625 °C/W RθJA value. At 85°C ambient, maximum allowable power drops to 125 mW (200 mW × [1 − (85−25)/625]), requiring series resistance adjustment to limit Zener current accordingly.
Does this part support reflow soldering per JEDEC J-STD-020?
Yes - the SOT-323 package is rated for moisture sensitivity level 1 and fully compatible with standard Pb-free reflow profiles (peak 260°C, 20–40 sec). No pre-bake is required, and the "Green" molding compound remains stable through multiple thermal cycles.
