Product details
Overview
BZX84C22Q-13-F from Diodes Incorporated is a 22 V, 350 mW surface-mount Zener diode in SOT23 package, rated for 5 mA test current with ±5% tolerance (20.8–23.3 V), 55 Ω dynamic impedance at 5 mA, and 0.1 µA maximum reverse leakage at 16.4 V. It serves as a precision voltage reference or overvoltage clamp in low-power analog signal conditioning circuits.
For engineers reviewing the BZX84C22Q-13-F datasheet, BZX84C22Q-13-F pinout, BZX84C22Q-13-F application, or BZX84C22Q-13-F equivalent, key selection criteria include Zener voltage accuracy, thermal resistance (357 °C/W), automotive qualification (AEC-Q101), RoHS/Green compliance, and SOT23 footprint compatibility in space-constrained PCB layouts.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain stable voltage across its terminals under varying load or supply conditions. Its planar die construction ensures consistent breakdown characteristics and long-term stability, while the matte tin-plated Alloy 42 leadframe guarantees reliable solderability per MIL-STD-202.
The device is qualified to AEC-Q101 standards, confirming suitability for automotive electronics where temperature cycling (-65 °C to +150 °C), humidity resistance (MSL Level 1), and mechanical robustness are mandatory. Its 350 mW power dissipation is valid only when terminals are held at ambient temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 22 V nominal, 20.8–23.3 V range at 5 mA - defines clamping/reference level with ±5% tolerance. |
| Power Dissipation (PD) | 350 mW - maximum continuous power at ambient-temperature terminals; derates linearly above 25 °C. |
| Zener Impedance (ZZT) | 55 Ω at 5 mA - indicates voltage regulation stiffness; lower values yield tighter regulation under load variation. |
| Reverse Leakage (IR) | 0.1 µA max at 16.4 V - ensures minimal standby current in high-impedance bias networks. |
| Thermal Resistance (RθJA) | 357 °C/W - determines junction temperature rise per watt; critical for reliability in enclosed or thermally isolated layouts. |
| Operating Temperature | -65 °C to +150 °C - supports extended-range automotive and industrial environments without derating. |
| AEC-Q101 Qualified | Yes - validated for automotive-grade reliability including temperature cycling, HAST, and ESD testing. |
Pinout & Package
Package: SOT23 - 3-terminal surface-mount plastic case (UL 94V-0), 0.008 g weight, 2.4 mm × 1.3 mm footprint, compatible with standard pick-and-place equipment and reflow profiles.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Pin 1) | Forward conduction terminal / cathode reference ground | Connected to circuit ground or lower potential node during Zener operation; polarity must match schematic symbol. |
| Cathode (Pin 2) | Zener breakdown terminal / regulated output node | Connected to voltage source via current-limiting resistor; maintains stable 22 V relative to anode under reverse bias. |
| No-Connect (Pin 3) | Internal die attach pad / thermal slug | Electrically isolated but thermally coupled to die; improves heat dissipation when soldered to copper pour. |
Key Features
| Feature | Design Value |
|---|---|
| Automotive qualification | AEC-Q101 compliant - enables use in engine control units, body electronics, and ADAS sensors without additional qualification effort. |
| Green material system | Halogen- and antimony-free molding compound (<900 ppm Br/Cl, <1000 ppm Sb) - meets global environmental regulations and end-of-life recycling requirements. |
| Lead-free plating | Matte tin over Alloy 42 - ensures solder joint integrity and eliminates Pb contamination risks in medical and consumer applications. |
| Low moisture sensitivity | JEDEC J-STD-020 Level 1 - allows indefinite floor life before reflow, eliminating bake requirements and reducing assembly cost. |
Applications
| Power Supply Monitoring | ADC Reference Stabilization |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMSZ5247B-TP (Micro Commercial) | 22 V nominal, ±5%, 500 mW rating, SOD-123 package - higher power but larger footprint and no AEC-Q101 qualification. | Preferred for non-automotive industrial power supplies where thermal margin >350 mW is required. | Select when board space permits larger package and automotive qualification is unnecessary. |
| BZX84-C22LT1G (ON Semiconductor) | 22 V nominal, ±5%, 350 mW, SOT-23, AEC-Q101 qualified - identical electrical specs but different marking code and tape/reel packaging (10k vs 3k). | Drop-in replacement in automotive designs requiring second-source availability and same thermal performance. | Choose for dual-sourcing strategy without layout or thermal redesign. |
Compared with MMSZ5247B-TP and BZX84-C22LT1G, BZX84C22Q-13-F uniquely combines AEC-Q101 qualification, 10,000-unit tape-and-reel packaging, and Diodes Inc.'s Green material compliance - making it optimal for high-volume automotive production with strict environmental and logistics requirements.

FAQ
What is the difference between BZX84C22Q-13-F and BZX84C22-13-F?
The "Q" suffix denotes AEC-Q101 qualification and automotive-grade screening, including extended temperature testing, humidity exposure, and mechanical stress validation. The non-Q version lacks this qualification and is intended for commercial applications only. Both share identical electrical specifications and SOT23 packaging.
Can BZX84C22Q-13-F be used in place of a 24 V Zener diode?
No - its nominal Zener voltage is 22 V (20.8–23.3 V range), not 24 V. Substituting it for a 24 V part would result in premature clamping or inaccurate reference generation. For 24 V applications, use BZX84C24Q-13-F, which has a 22.8–25.6 V range at 5 mA.
Is the third pin (SOT23 Pin 3) electrically connected?
No - Pin 3 is an internal die attach pad with no electrical connection to the semiconductor die. It is thermally conductive and may be soldered to a copper pour to improve heat dissipation, but must remain unconnected in the schematic netlist.
What is the maximum allowable reverse voltage before breakdown?
The rated Zener voltage of 22 V is specified at 5 mA test current. Breakdown begins gradually above ~20.8 V and stabilizes near nominal voltage at rated current. Applying reverse voltage significantly above 23.3 V without current limiting will exceed power dissipation limits and cause thermal failure.
