Product details
Overview
BZX84J-B5V6/DG/B3X from Nexperia is a ±2 % tolerance Zener diode in SOD323F (SC-90) package, rated for 5.6 V nominal regulation voltage, 550 mW total power dissipation, and AEC-Q101 qualification. It delivers low differential resistance (400 Ω at IZ = 5 mA), stable temperature coefficient (−2.0 to +2.5 mV/K), and supports automotive-grade voltage reference and overvoltage clamping in compact PCB layouts.
For engineers reviewing the BZX84J-B5V6/DG/B3X datasheet, BZX84J-B5V6/DG/B3X pinout, BZX84J-B5V6/DG/B3X application, or BZX84J-B5V6/DG/B3X equivalent, this page provides verified electrical parameters, thermal behavior, cathode/anode terminal mapping, automotive compliance status, and direct substitution guidance for precision low-power regulation designs.
Technical Context
This Zener diode operates in reverse breakdown with tightly controlled VZ = 5.49–5.71 V at IZ = 5 mA and exhibits low dynamic impedance (rdiff ≤ 400 Ω), enabling stable reference generation under varying load conditions. Its −2.0 to +2.5 mV/K temperature coefficient ensures minimal drift across −55 °C to +150 °C ambient range.
Designed for surface-mount use in space-constrained applications, it features non-repetitive peak reverse power dissipation of 100 W (≤6.8 V types) and junction-to-ambient thermal resistance of 230 K/W on FR4 PCB. The device meets AEC-Q101 stress test requirements for automotive discrete semiconductors.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C5V6 | ±5 % tolerance (5.2–6.0 V), higher rdiff (480 Ω), same SOD323F package | Acceptable where cost sensitivity outweighs precision requirement; not AEC-Q101 qualified | Select when design tolerates wider VZ spread and automotive qualification is unnecessary |
| MMSZ5232B | ±5 % tolerance, 500 mW Ptot, SOD-123 package (larger footprint), no AEC-Q101 certification | Requires PCB layout revision due to different land pattern; suitable for industrial-only deployments | Choose only if existing SOD-123 footprint is fixed and automotive compliance is not required |
Compared with BZX84J-B5V6/DG/B3X, the BZX84-C5V6 offers lower cost but sacrifices regulation accuracy and automotive qualification, while MMSZ5232B trades package compatibility and qualification for broader distributor availability in non-automotive contexts.

FAQ
What is the maximum continuous forward current for BZX84J-B5V6/DG/B3X?
The absolute maximum forward current is 250 mA per the limiting values table. However, typical forward voltage is specified at 100 mA (VF ≤ 1.1 V), and sustained operation above 100 mA requires thermal derating based on PCB copper area and ambient temperature to avoid exceeding 150 °C junction temperature.
Does BZX84J-B5V6/DG/B3X support reflow soldering only?
Yes - the datasheet explicitly states reflow soldering is the only recommended method. Wave or hand soldering is not supported due to thermal limitations of the SOD323F package. Reflow profile must comply with JEDEC J-STD-020 moisture sensitivity level (MSL) requirements and peak temperature limits defined in the soldering section.
How does the temperature coefficient affect regulation accuracy over temperature?
With a specified SZ of −2.0 to +2.5 mV/K, VZ shifts up to ±25 mV over a 100 °C range (e.g., −40 °C to +60 °C). This translates to ±0.45 % deviation from nominal 5.6 V, making it suitable for applications where reference stability within ±0.5 % is acceptable without active compensation.
Can BZX84J-B5V6/DG/B3X be used in parallel for higher power handling?
No - Zener diodes exhibit negative temperature coefficient and mismatched VZ tolerances, causing current hogging and thermal runaway when paralleled. For higher power, use a single higher-rated Zener or implement active regulation with a transistor-based shunt amplifier instead.
