Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX584C11-G3-08 | Same electrical specs but commercial-grade (non-AEC-Q101 qualified); identical SOD-523 package and marking code P: | Not approved for automotive use; suitable only for industrial or consumer applications without automotive reliability requirements | Select when AEC-Q101 compliance is not required and cost optimization is prioritized |
| MMBZ5240BS-7-F | 10 V nominal Zener (±5 %), 200 mW rating, SOD-323 package; 15 Ω dynamic resistance at 20 mA; no AEC-Q101 listing | Larger footprint (1.7 mm × 1.3 mm) and different thermal resistance; lacks automotive qualification | Consider only if 10 V reference suffices and board layout allows SOD-323 spacing |
Compared with BZX584C11-HG3-08, the G3 variant offers identical performance at lower qualification cost, while MMBZ5240BS-7-F trades tighter voltage match for larger size and unverified automotive suitability-making BZX584C11-HG3-08 the sole AEC-Q101-compliant 11 V SOD-523 Zener in this family.

FAQ
What is the Zener voltage tolerance of BZX584C11-HG3-08?
The BZX584C11-HG3-08 has a Zener voltage tolerance of ±5 %, meaning its nominal 11 V regulation falls between 10.4 V and 11.6 V at 5 mA test current. This tolerance is guaranteed across the full operating temperature range and supports repeatable voltage reference design without external trimming. The BZX584C11-HG3-08 achieves this via tightly controlled silicon process parameters and post-package screening.
Is BZX584C11-HG3-08 qualified for automotive applications?
Yes, BZX584C11-HG3-08 is AEC-Q101 qualified, confirming compliance with stress tests including temperature cycling, high-temperature operating life, and mechanical shock per JESD22 standards. This qualification makes it suitable for under-hood and cabin electronics where reliability across -40 °C to +125 °C ambient is mandatory. The BZX584C11-HG3-08 carries the "HG3" suffix explicitly denoting AEC-Q101 compliance.
What is the maximum power dissipation of BZX584C11-HG3-08 on a standard FR-4 board?
The BZX584C11-HG3-08 is rated for 200 mW maximum power dissipation when mounted on an FR-4 board using Vishay's recommended soldering footprint. This value assumes natural convection cooling and accounts for thermal resistance of 600 K/W junction-to-ambient. Exceeding 200 mW risks exceeding the 150 °C junction temperature limit. The BZX584C11-HG3-08 datasheet specifies higher 300 mW rating only with 5 mm × 5 mm copper pad enhancement.
Does BZX584C11-HG3-08 have a specified dynamic resistance?
Yes, BZX584C11-HG3-08 has a maximum dynamic resistance (ZZ) of 8 Ω measured at 5 mA test current (IZT). This low impedance ensures minimal voltage deviation under changing load conditions, making it suitable for precision reference and low-noise biasing. The BZX584C11-HG3-08 achieves this via optimized Zener junction geometry and doping profile, verified per the Vishay document 85793 Rev. 1.9.
What is the reverse leakage current specification for BZX584C11-HG3-08?
The BZX584C11-HG3-08 specifies a maximum reverse leakage current (IR) of 0.1 μA at VR = 8.8 V (80 % of nominal Zener voltage). This ultra-low leakage preserves signal integrity in high-impedance circuits such as sensor bias networks and ADC references. The BZX584C11-HG3-08 maintains this performance across its full operating temperature range, validated per the Electrical Characteristics table in Vishay document 85793.
