For engineers reviewing the BZX584C7V5-HG3-08 datasheet, BZX584C7V5-HG3-08 pinout, BZX584C7V5-HG3-08 application, or BZX584C7V5-HG3-08 equivalent, key selection criteria include Zener voltage stability under pulse conditions, low dynamic resistance (≤30 Ω at 5 mA), temperature coefficient (+3 to +7 × 10⁻⁴/°C), and MSL Level 1 soldering compatibility.
Technical Context
The BZX584C7V5-HG3-08 operates as a single-element, silicon planar Zener diode optimized for precision voltage regulation and reference in space-constrained circuits. Its electrical behavior is defined at 25 °C ambient, with specified reverse leakage ≤1 μA at 5.6 V and dynamic resistance of 6 Ω (typ.) / ≤30 Ω (max.) at IZT = 5 mA.
Thermal performance is characterized by RthJA = 600 K/W on standard FR-4 footprint and RthJL = 200 K/W to lead, supporting operation up to Tj = 150 °C. The device exhibits a positive temperature coefficient (+3 to +7 × 10⁻⁴/°C), indicating increasing VZ with rising junction temperature.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX584C7V5-G3-08 | Same electrical specs but commercial grade (non-AEC-Q101); identical SOD-523 package and marking code "3:" | Lacks automotive qualification; suitable for consumer/industrial use where AEC stress testing not required | Select when cost sensitivity outweighs automotive reliability requirements and lifecycle traceability is not mandated |
| MMBZ5227BS-7-F | 7.5 V Zener, SOT-323 package (2.1 mm × 1.3 mm), 350 mW Ptot, ±5 % tolerance, no AEC-Q101 rating | Larger footprint and higher power rating; not drop-in compatible due to different package and thermal profile | Choose only if board layout allows SOT-323 and higher power dissipation is needed; not a mechanical or qualification substitute |
Compared with BZX584C7V5-HG3-08, the G3 variant trades automotive qualification for lower unit cost in non-automotive systems, while MMBZ5227BS-7-F offers higher power handling in a larger package but lacks AEC-Q101 validation and requires PCB redesign.

FAQ
What is the Zener voltage tolerance of the BZX584C7V5-HG3-08?
The BZX584C7V5-HG3-08 has a Zener voltage tolerance of ±5 %, meaning its nominal 7.5 V rating spans 7.0 V (minimum) to 7.9 V (maximum) at 5 mA test current. This tolerance is guaranteed across operating temperature and lifetime, and is confirmed in the Vishay BZX584C-Series datasheet revision 1.9. The BZX584C7V5-HG3-08 maintains this specification under AEC-Q101 stress conditions.
Is the BZX584C7V5-HG3-08 qualified for automotive applications?
Yes, the BZX584C7V5-HG3-08 is AEC-Q101 qualified, as indicated by the "HG3" suffix in its ordering code. It undergoes rigorous stress testing including temperature cycling, highly accelerated life testing (HALT), and ESD per AEC-Q101 Rev. E. This qualification makes the BZX584C7V5-HG3-08 suitable for under-hood and cabin electronics where reliability across -40 °C to +125 °C is mandatory.
What is the maximum power dissipation for the BZX584C7V5-HG3-08 on a standard PCB?
The BZX584C7V5-HG3-08 is rated for 200 mW power dissipation when mounted on an FR-4 board using Vishay's recommended soldering footprint. This value assumes natural convection cooling and is derated linearly above 25 °C ambient. The BZX584C7V5-HG3-08 can dissipate up to 300 mW with a 5 mm × 5 mm copper pad, but standard layout practices should adhere to the 200 mW limit unless thermal modeling confirms margin.
What does the "HG3" suffix mean in BZX584C7V5-HG3-08?
The "HG3" suffix identifies the BZX584C7V5-HG3-08 as RoHS-compliant and AEC-Q101 qualified, distinguishing it from the commercial-grade "G3" variant. "H" denotes automotive qualification, "G3" indicates green (halogen-free) RoHS compliance, and "-08" specifies 8 mm tape on 7-inch reel packaging. This coding is standardized across the BZX584C-Series and directly referenced in Vishay document 85793.
What is the thermal resistance junction-to-ambient for the BZX584C7V5-HG3-08?
The thermal resistance junction-to-ambient (RthJA) for the BZX584C7V5-HG3-08 is 600 K/W when mounted on an FR-4 board with Vishay's recommended footprint, per JEDEC 51-3. This value reflects natural convection conditions and must be used with the 150 °C maximum junction temperature to calculate allowable power dissipation at elevated ambient temperatures. The BZX584C7V5-HG3-08 achieves this RthJA due to its SOD-523 package geometry and thermal interface design.
