Product details
Overview
BZX584C3V0-HG3-08 from Vishay Semiconductors is a surface-mount Zener diode in the SOD-523 package, rated for 3.0 V nominal Zener voltage at 5 mA test current, ±5 % tolerance, 200 mW power dissipation on FR-4 board, and AEC-Q101 qualified for automotive applications. It provides precise voltage regulation in low-power biasing and reference circuits.
For engineers reviewing the BZX584C3V0-HG3-08 datasheet, BZX584C3V0-HG3-08 pinout, BZX584C3V0-HG3-08 application, or BZX584C3V0-HG3-08 equivalent, key selection criteria include Zener voltage accuracy, dynamic resistance (≤80 Ω at IZT), temperature coefficient (–9 to –3 ×10⁻⁴/°C), reverse leakage (≤10 μA at VR = 1 V), and AEC-Q101 qualification status.
Technical Context
The BZX584C3V0-HG3-08 operates as a single-element, silicon planar Zener diode optimized for stable voltage reference and overvoltage protection in space-constrained PCB layouts. Its design targets low-current regulation (IZT = 5 mA) with tight VZ tolerance and low dynamic impedance.
It features a negative temperature coefficient (αVZ = –9 to –3 ×10⁻⁴/°C), indicating decreasing Zener voltage with rising junction temperature - critical for thermal stability in automotive ambient environments. The device is qualified per AEC-Q101 Rev. E and rated for junction temperatures up to 150 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 2.8 V min. / 3.0 V nom. / 3.2 V max. at IZT = 5 mA - ensures stable 3.0 V reference within ±5 % across production lot |
| Power Dissipation (Ptot) | 200 mW on FR-4 with recommended footprint - defines maximum continuous power handling without derating |
| Dynamic Resistance (ZZ) | ≤80 Ω at IZT = 5 mA (≤100 Ω typical) - determines regulation stiffness under small-signal load variations |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBZ5222BS-7-F | Zener voltage 3.0 V (±5 %), but rated at 225 mW Ptot and not AEC-Q101 qualified; dynamic resistance 100 Ω typical | Suitable for commercial-grade portable electronics only; lacks automotive stress validation and thermal robustness | Select when AEC-Q101 is unnecessary and higher power margin is needed on non-automotive boards |

FAQ
What is the Zener voltage tolerance of the BZX584C3V0-HG3-08?
The BZX584C3V0-HG3-08 has a Zener voltage tolerance of ±5 %, specified as 2.8 V minimum to 3.2 V maximum at 5 mA test current (IZT). This tolerance is guaranteed across the full operating temperature range and applies to all units shipped under the HG3 grade, which includes AEC-Q101 qualification and RoHS compliance.
Is the BZX584C3V0-HG3-08 suitable for automotive applications?
Yes, the BZX584C3V0-HG3-08 is explicitly AEC-Q101 qualified, meaning it has passed stress tests including high-temperature operating life, temperature cycling, unbiased highly accelerated stress testing, and electrostatic discharge per JESD22-A114. Its junction temperature rating of 150 °C and storage range of –65 to +150 °C make it suitable for under-hood and cabin-mounted automotive modules.
What is the maximum power dissipation for the BZX584C3V0-HG3-08 on a standard FR-4 PCB?
The BZX584C3V0-HG3-08 is rated for 200 mW maximum power dissipation when mounted on an FR-4 board using Vishay's recommended soldering footprint. With a 5 mm × 5 mm copper pad, its rating increases to 300 mW. Thermal resistance junction-to-ambient is 600 K/W under standard conditions, so sustained operation above 200 mW requires careful thermal analysis.
Does the BZX584C3V0-HG3-08 have a defined temperature coefficient?
Yes, the BZX584C3V0-HG3-08 has a temperature coefficient of Zener voltage (αVZ) ranging from –9 to –3 ×10⁻⁴/°C at IZT = 5 mA. This negative coefficient means its Zener voltage decreases slightly as temperature rises - a key parameter for designing thermally stable references in automotive and industrial environments.
What packaging and reel configuration is used for the BZX584C3V0-HG3-08?
The BZX584C3V0-HG3-08 is supplied in tape-and-reel format: 8 mm carrier tape on 7-inch reels containing 8000 units per reel. The part marking code is ":4", consistent with the BZX584C-Series SOD-523 package identification. Minimum order quantity matches the reel size: 8000 units.
