Product details
Overview
BZX584C24-HG3-08 from Vishay Semiconductors is a surface-mount silicon Zener diode in the SOD-523 package, rated for 24 V nominal Zener voltage (±5 % tolerance), 5 mA test current, 25 Ω dynamic resistance at IZT, and 200 mW power dissipation on FR-4 board with recommended footprint. It serves as a precision voltage reference or overvoltage clamp in space-constrained automotive and industrial power management circuits.
For engineers reviewing the BZX584C24-HG3-08 datasheet, BZX584C24-HG3-08 pinout, BZX584C24-HG3-08 application, or BZX584C24-HG3-08 equivalent, key selection criteria include AEC-Q101 qualification, ±5 % VZ tolerance at 5 mA, low leakage (<50 nA at 19.2 V), thermal resistance of 600 K/W, and SOD-523 footprint compatibility with high-density PCB layouts.
Technical Context
The BZX584C24-HG3-08 operates as a single-element, two-terminal Zener diode optimized for stable reverse-bias regulation. Its 24 V nominal breakdown voltage is specified at 5 mA test current with 25 Ω dynamic impedance and +8 × 10−4/°C temperature coefficient - enabling predictable voltage reference behavior across −65 °C to +150 °C ambient range.
AEC-Q101 qualification confirms suitability for automotive electronics, while the SOD-523 package (1.45 mm × 0.9 mm × 0.7 mm) supports automated placement and reflow soldering per J-STD-020 MSL Level 1. Maximum power dissipation is 200 mW on standard FR-4 with recommended footprint, rising to 300 mW with 5 mm × 5 mm copper pad.
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 |
|---|---|---|---|
| MMBZ5249BS-7-F | 24 V nominal, ±5 %, 200 mW, SOT-323 package (2.2 mm × 1.35 mm), 100 Ω ZZ at 20 mA | Larger footprint and higher dynamic impedance reduce accuracy in precision reference use cases | Select when existing SOT-323 layout prohibits SOD-523 adoption and tighter regulation is not required |

FAQ
What is the Zener voltage tolerance of the BZX584C24-HG3-08?
The BZX584C24-HG3-08 has a Zener voltage tolerance of ±5 % at 5 mA test current, meaning its actual breakdown voltage falls between 22.8 V and 25.6 V under nominal conditions. This tolerance is guaranteed across the full operating temperature range and is verified during AEC-Q101 qualification testing. The BZX584C24-HG3-08 maintains this specification without derating up to 150 °C junction temperature.
Is the BZX584C24-HG3-08 qualified for automotive applications?
Yes, the BZX584C24-HG3-08 is AEC-Q101 qualified, confirming compliance with stress tests including temperature cycling, high-temperature operating life, and unbiased highly accelerated stress testing. This qualification applies specifically to the HG3 suffix variant and covers the full SOD-523 package family. The BZX584C24-HG3-08 is approved for use in engine control units, body control modules, and ADAS power domains.
What is the maximum power dissipation of the BZX584C24-HG3-08 on a standard PCB?
The BZX584C24-HG3-08 delivers 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, dissipation increases to 300 mW due to improved thermal conduction. Both values assume ambient temperature of 25 °C and are validated per JEDEC 51-3 standards. The BZX584C24-HG3-08 must be operated within these limits to maintain 150 °C maximum junction temperature.
Does the BZX584C24-HG3-08 have a specified reverse leakage current?
Yes, the BZX584C24-HG3-08 specifies a maximum reverse leakage current of 50 nA at VR = 19.2 V (80 % of nominal Zener voltage). This value is measured at 25 °C and remains below 200 nA across the full −65 °C to +150 °C storage temperature range. Low leakage ensures minimal impact on battery-powered systems and high-impedance sensor interfaces where the BZX584C24-HG3-08 is deployed.
What is the temperature coefficient of the BZX584C24-HG3-08?
The BZX584C24-HG3-08 has a temperature coefficient of +8 × 10−4/°C at 5 mA test current, indicating a positive voltage drift with increasing temperature. This coefficient is measured relative to the 24 V nominal Zener voltage and remains stable across the operational junction temperature range. The BZX584C24-HG3-08 uses this predictable drift characteristic in compensated reference designs where secondary temperature sensing corrects for offset.
