Product details
Overview
BZX84B5V6Q-13-F from Diodes Incorporated is a precision ±2% tolerance 5.6 V Zener diode in SOT23 package, rated for 350 mW power dissipation at ambient temperature, with 40 Ω dynamic impedance at 5 mA test current and 1.0 µA maximum reverse leakage at 2.0 V, used for voltage regulation and reference in automotive power supply monitoring circuits.
For engineers reviewing the BZX84B5V6Q-13-F datasheet, BZX84B5V6Q-13-F pinout, BZX84B5V6Q-13-F application, or BZX84B5V6Q-13-F equivalent, key selection criteria include Zener voltage tolerance, thermal resistance (357 °C/W), junction-to-ambient derating behavior, and AEC-Q101 qualification status for automotive-grade reliability.
Technical Context
This device operates as a two-terminal voltage reference with sharp reverse breakdown at 5.6 V nominal, specified under 5 mA test current and characterized with low dynamic impedance (40 Ω) and tight ±2% initial tolerance. Its temperature coefficient of –2.0 mV/°C ensures stable regulation across –65°C to +150°C operating range.
The SOT23 package enables high-density PCB layout and automated placement, while its AEC-Q101 qualification confirms suitability for automotive electronics requiring robust transient immunity and long-term parametric stability under thermal cycling and humidity exposure.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMSZ5232B-TP (Micro Commercial) | Same 5.6 V nominal, ±5% tolerance, 500 mW rating, SOD-123 package | Larger footprint; higher power but looser tolerance reduces precision in feedback paths | Select when cost sensitivity outweighs regulation accuracy and board space is unconstrained |
| BZX84-C5V6 (Nexperia) | 5.6 V nominal, ±5% tolerance, 300 mW rating, SOT23 package, no AEC-Q101 qualification | Non-automotive grade; lacks thermal cycling validation and failure mode documentation | Acceptable for consumer-grade power supplies where AEC-Q101 compliance is not required |
Compared with MMSZ5232B-TP and BZX84-C5V6, BZX84B5V6Q-13-F delivers tighter ±2% tolerance and AEC-Q101 qualification in the same SOT23 footprint-critical for automotive voltage monitors and precision industrial references where parametric stability and reliability certification are mandatory.

FAQ
What is the maximum reverse voltage before breakdown for BZX84B5V6Q-13-F?
The nominal Zener voltage is 5.6 V, with guaranteed breakdown occurring between 5.49 V and 5.71 V at 5 mA test current. Below 5.49 V, reverse leakage remains ≤1.0 µA at 2.0 V; no hard "maximum reverse voltage" is defined outside the Zener region-operation above 5.71 V risks exceeding power limits if current is uncontrolled.
Is BZX84B5V6Q-13-F compatible with lead-free reflow profiles?
Yes. It uses matte tin-plated terminals over Alloy 42 leadframe and is qualified for Pb-free soldering per J-STD-020 Level 1 moisture sensitivity. Peak reflow temperature up to 260°C is supported without degradation, and the SOT23 package withstands standard SAC305 thermal cycles.
How does the –2.0 mV/°C temperature coefficient affect regulation accuracy?
Over a –40°C to +125°C range, the coefficient causes a total shift of approximately ±0.336 V (168°C × 2.0 mV/°C). This is factored into system-level tolerance budgets-e.g., combined with ±2% initial tolerance, total drift stays within ±4.7% of 5.6 V across full automotive temperature range.
Can BZX84B5V6Q-13-F replace BZX84-C5V6 in existing designs?
Yes, electrically and physically-same SOT23 footprint and 5.6 V nominal voltage-but BZX84B5V6Q-13-F offers ±2% tolerance (vs. ±5%), 350 mW rating (vs. 300 mW), and AEC-Q101 qualification. No layout change is needed, though system-level validation is recommended for automotive use cases.
