Overview
BZX584C36-HG3-08 from Vishay Semiconductors is a 36 V ±5 % Zener diode in SOD-523 package, rated for 2 mA test current, 0.05 μA reverse leakage at 28.8 V, 35 Ω dynamic resistance, and +8 × 10⁻⁴/°C temperature coefficient - used for precision voltage reference and overvoltage protection in space-constrained automotive ECUs.
For engineers reviewing the BZX584C36-HG3-08 datasheet, BZX584C36-HG3-08 pinout, BZX584C36-HG3-08 application, or BZX584C36-HG3-08 equivalent, key selection criteria include AEC-Q101 qualification, 200 mW power dissipation on FR-4, MSL Level 1 handling, and SOD-523 footprint compatibility with high-density PCB layouts.
Technical Context
The BZX584C36-HG3-08 operates as a single-element, silicon planar Zener diode optimized for stable reverse-biased voltage regulation. Its 36 V nominal Zener voltage is specified at 2 mA (IZT1), with dynamic resistance of 35 Ω (max) and temperature coefficient of +8 × 10⁻⁴/°C - indicating positive drift with rising junction temperature.
AEC-Q101 qualification confirms suitability for automotive applications requiring robust thermal cycling, humidity resistance, and mechanical shock performance. The device uses UL 94 V-0 molding compound and exhibits 600 K/W thermal resistance junction-to-ambient on standard FR-4 layout.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 36 V nominal, ±5 % tolerance → ensures stable 34.2–37.8 V regulation under 2 mA bias |
| Test Current (IZT) | 2 mA → defines operating point for VZ specification and dynamic resistance measurement |
| Reverse Leakage (IR) | 0.05 μA max at 28.8 V → guarantees minimal standby current in voltage-sense circuits |
| Dynamic Resistance (ZZ) | 35 Ω max at IZT → limits output impedance variation during load transients |
| Power Dissipation (Ptot) | 200 mW on FR-4 with recommended footprint → sets maximum continuous DC power in typical PCB layout |
| Temperature Coefficient (αVZ) | +8 × 10⁻⁴/°C → predicts +28.8 mV/°C drift across 36 V nominal, critical for temp-stable references |
| Junction Temperature (Tj) | 150 °C max → defines upper thermal limit for reliable long-term operation |

The BZX584C36-HG3-08 has a Zener voltage tolerance of ±5 %, specified at a test current (IZT) of 2 mA. This means its nominal 36 V breakdown occurs between 34.2 V and 37.8 V under that exact bias condition, as confirmed in the Vishay datasheet revision 1.9, page 2.
Is BZX584C36-HG3-08 qualified for automotive applications?
Yes, BZX584C36-HG3-08 is AEC-Q101 qualified, as indicated by the "HG3" suffix in its ordering code. This certification covers stress tests including temperature cycling, high-accelerated temperature/humidity stress, and mechanical shock - validating its use in automotive electronic control units per the Vishay datasheet section "Ordering Information".
What is the maximum power dissipation of BZX584C36-HG3-08 on a standard FR-4 PCB?
The BZX584C36-HG3-08 has a maximum power dissipation of 200 mW when mounted on an FR-4 board using Vishay's recommended soldering footprint. This value assumes ambient temperature of 25 °C and is derived from the absolute maximum ratings table in the datasheet (page 2), where Ptot = 200 mW is explicitly listed for the standard layout.
What does the "-HG3" suffix signify in BZX584C36-HG3-08?
The "-HG3" suffix in BZX584C36-HG3-08 denotes RoHS-compliant construction and AEC-Q101 qualification. Per the Vishay datasheet (page 1, "FEATURES"), "Base P/N-HG3" identifies the automotive-grade variant, distinguishing it from the commercial "-G3" version - confirming BZX584C36-HG3-08 meets automotive reliability standards.
What is the reverse leakage current specification for BZX584C36-HG3-08?
The BZX584C36-HG3-08 specifies a maximum reverse leakage current (IR) of 0.05 μA at a reverse voltage (VR) of 28.8 V (80 % of nominal VZ). This value is documented in the "ELECTRICAL CHARACTERISTICS" table on page 2 of the Vishay datasheet, ensuring minimal quiescent current in high-impedance reference circuits.
