Overview
BZX884B4V7L-HG3-08 from Vishay Semiconductors is a silicon planar Zener diode in DFN1006-2A package, rated for 4.7 V nominal Zener voltage at 5 mA test current, ±2 % tolerance, 300 mW power dissipation on FR-4, and AEC-Q101 qualified for automotive applications.
For engineers reviewing the BZX884B4V7L-HG3-08 datasheet, BZX884B4V7L-HG3-08 pinout, BZX884B4V7L-HG3-08 application, or BZX884B4V7L-HG3-08 equivalent, key selection factors include its ultra-small 1.0 mm × 0.6 mm footprint, low 3 μA reverse leakage at 1 V, 80 Ω dynamic impedance at 5 mA, and -5 to +2 × 10⁻⁴/°C temperature coefficient - critical for precision voltage reference and ESD-protected bias networks.
Technical Context
This device operates as a single-element, surface-mount Zener diode optimized for stable voltage regulation and clamping in space-constrained circuits. Its DFN1006-2A package features wettable flanks for automated optical inspection compliance without X-ray, and it meets AEC-Q101 stress testing requirements for automotive under-hood use.
The BZX884B4V7L-HG3-08 delivers 4.7 V regulation with tight ±2 % tolerance and low 80 Ω dynamic resistance at IZT = 5 mA, enabling predictable clamping behavior across temperature (–55 °C to +150 °C) and supporting low-noise analog reference design where leakage <3 μA at VR = 1 V matters.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STMicroelectronics BZT52-B4V7S | Same 4.7 V / ±2 % spec, but SOD-523 package (1.3 × 0.85 mm); higher RthJA = 500 K/W | Larger footprint; not AEC-Q101 qualified; lacks wettable flanks | Choose for cost-sensitive consumer boards where AOI verification is not required |
| ON Semiconductor MMBZ5225BS | 4.7 V / ±5 % tolerance; SOT-23 package; 350 mW Ptot; no AEC-Q101 rating | Looser voltage tolerance; larger 2.9 × 1.3 mm footprint; higher thermal resistance | Choose only if ±5 % regulation is acceptable and board space permits SOT-23 |
Compared with BZX884B4V7L-HG3-08, the BZT52-B4V7S offers identical electrical specs but sacrifices automotive qualification and AOI-ready packaging, while the MMBZ5225BS trades precision and miniaturization for higher power handling in legacy layouts.

FAQ
What is the Zener voltage tolerance of the BZX884B4V7L-HG3-08?
The BZX884B4V7L-HG3-08 has a Zener voltage tolerance of ±2 %, meaning its nominal 4.7 V rating falls between 4.61 V and 4.79 V at 5 mA test current. This tight tolerance is specified per the Vishay datasheet Rev. 1.6 and enables direct use in precision reference circuits without calibration. The BZX884B4V7L-HG3-08 achieves this via laser-trimmed silicon process control and is verified across temperature ranges from –55 °C to +150 °C.
Is the BZX884B4V7L-HG3-08 qualified for automotive applications?
Yes, the BZX884B4V7L-HG3-08 is AEC-Q101 qualified, as confirmed in the Vishay ordering information table and absolute maximum ratings section. It undergoes stress testing including high-temperature operating life, temperature cycling, and human-body-model ESD ≥ 2 kV. The BZX884B4V7L-HG3-08 is intended for under-hood and cabin applications such as sensor biasing and power rail clamping where automotive reliability standards apply.
What is the maximum power dissipation of the BZX884B4V7L-HG3-08?
The BZX884B4V7L-HG3-08 has a maximum power dissipation of 300 mW when mounted on an FR-4 board using Vishay's recommended soldering footprint. This value is measured at Tamb = 25 °C and reflects thermal performance enabled by the DFN1006-2A package's low RthJA of 420 K/W. Derating is required above 25 °C ambient, and the BZX884B4V7L-HG3-08 must not exceed its 150 °C maximum junction temperature under continuous operation.
Does the BZX884B4V7L-HG3-08 have wettable flanks?
Yes, the BZX884B4V7L-HG3-08 features wettable flank terminals as part of its DFN1006-2A package construction. This allows standard automated optical inspection (AOI) to verify solder joint quality on both top and side surfaces - eliminating the need for X-ray inspection in automotive manufacturing lines. The BZX884B4V7L-HG3-08 meets AOI requirements per J-STD-020 MSL level 1 and is documented in Vishay's package drawings and application notes.
What is the reverse leakage current specification for the BZX884B4V7L-HG3-08?
The BZX884B4V7L-HG3-08 specifies a maximum reverse leakage current of 3 μA at 1 V reverse voltage (VR), per the Electrical Characteristics table on page 2 of the Vishay datasheet. This low leakage supports energy-efficient operation in battery-powered systems and precision analog circuits where standby current must be minimized. The BZX884B4V7L-HG3-08 maintains this performance across its full operating temperature range of –55 °C to +150 °C.
