Product details
Overview
BZX84B5V6-7-F from Diodes Incorporated is a precision 5.6 V ±2% tolerance Zener diode in SOT23 package, rated for 350 mW power dissipation at 25°C ambient, with 40 Ω dynamic impedance at 5 mA test current and 1.0 µA maximum reverse leakage at 2.0 V. It serves as a voltage reference or overvoltage clamp in low-power analog circuits, DC-DC feedback loops, and microcontroller reset supervision.
For engineers reviewing the BZX84B5V6-7-F datasheet, BZX84B5V6-7-F pinout, BZX84B5V6-7-F application, or BZX84B5V6-7-F equivalent, key selection criteria include zener voltage tolerance (±2%), 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 diode, conducting in reverse breakdown when cathode voltage exceeds anode by ≥5.49 V (min) to ≤5.71 V (max) at 5 mA. Its temperature coefficient of +2.5 mV/°C enables predictable drift compensation in stable reference designs.
The SOT23 package supports automated pick-and-place assembly and provides 0.008 g mass with UL 94V-0 flammability rating. Thermal performance is defined under two conditions: 350 mW rating assumes terminals held at ambient temperature; 300 mW applies when mounted on FR-4 PCB with recommended pad layout.
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 |
|---|---|---|---|
| MMBZ5232BS-7-F | 5.6 V ±5% tolerance, 300 mW rating, 100 Ω ZZT at 20 mA | Higher impedance and looser tolerance reduce reference accuracy but improve surge handling | Select for cost-sensitive non-critical clamping where ±5% is acceptable |
| BZX84-C5V6 | 5.6 V ±5% tolerance, same SOT23 package, no AEC-Q101 qualification | Lacks automotive reliability validation; suitable only for commercial-grade applications | Choose when AEC-Q101 is not required and tighter tolerance is unnecessary |
Compared with MMBZ5232BS-7-F and BZX84-C5V6, BZX84B5V6-7-F delivers superior voltage accuracy (±2% vs. ±5%), lower dynamic impedance (40 Ω vs. 100 Ω), and AEC-Q101 qualification-making it optimal for automotive reset circuits and precision analog references where regulation stability is critical.

FAQ
What is the maximum reverse leakage current for BZX84B5V6-7-F at 2.0 V?
The maximum reverse leakage current is 1.0 µA at VR = 2.0 V and TA = 25°C, as specified in the Electrical Characteristics table. This low leakage ensures minimal power loss in standby or high-impedance bias networks, supporting ultra-low-power system designs.
Is BZX84B5V6-7-F qualified for automotive use?
Yes, BZX84B5V6-7-F is qualified to AEC-Q101 standards for high-reliability automotive applications. The "-Q" suffix denotes automotive grade, and this part carries full qualification documentation including stress testing, failure analysis, and lifetime reliability data per AEC specifications.
How does the temperature coefficient affect voltage regulation?
The temperature coefficient is +2.5 mV/°C at 5 mA, meaning the zener voltage increases by 2.5 mV per degree Celsius rise in junction temperature. This positive drift allows predictable compensation in reference circuits where opposing negative TC components (e.g., bandgap references) are used.
Can BZX84B5V6-7-F be used in place of BZX84-C5V6?
Yes, BZX84B5V6-7-F is a direct functional upgrade to BZX84-C5V6, offering tighter ±2% tolerance (vs. ±5%), AEC-Q101 qualification, and identical SOT23 footprint. No layout changes are needed, but designers benefit from improved accuracy and automotive reliability assurance.
