Product details
Overview
BZX84C5V6-7 from Diodes Incorporated is a 5.6 V, 350 mW surface-mount Zener diode in SOT23 package, designed for precision voltage regulation and reference applications at 5 mA test current, with 40 Ω dynamic impedance and ±2.0 mV/°C temperature coefficient. It operates across –65 °C to +150 °C and supports automotive-grade reliability per AEC-Q101.
For engineers reviewing the BZX84C5V6-7 datasheet, BZX84C5V6-7 pinout, BZX84C5V6-7 application, or BZX84C5V6-7 equivalent, key selection criteria include nominal Zener voltage tolerance (±7.1%), low reverse leakage (1.0 µA @ 2.0 V), thermal resistance (357 °C/W), and compatibility with automated SMT assembly on FR-4 PCBs.
Technical Context
This Zener diode employs planar die construction for stable breakdown characteristics and low noise performance. Its 5.6 V nominal Zener voltage is specified at 5.0 mA test current (IZT), with a maximum Zener impedance of 40 Ω at 1 kHz and 5 mA, ensuring tight regulation under moderate load variations.
The device exhibits a negative temperature coefficient of –2.0 mV/°C, enabling predictable drift compensation in reference circuits. It is rated for 350 mW power dissipation when terminals are held at ambient temperature, and its thermal resistance (RθJA = 357 °C/W) reflects optimized heat transfer in standard SOT23 mounting conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 5.6 V nominal, 5.2–6.0 V range @ 5 mA - defines stable regulation point for biasing or reference circuits |
| Power Dissipation (PD) | 350 mW - maximum continuous power at ambient-temperature terminals, supporting compact board-level regulation |
| Zener Impedance (ZZT) | 40 Ω @ 1 kHz, 5 mA - low dynamic resistance ensures minimal output voltage variation under current load changes |
| Reverse Leakage (IR) | 1.0 µA @ VR = 2.0 V - ultra-low off-state current preserves signal integrity in high-impedance sensing nodes |
| Temperature Coefficient | –2.0 mV/°C - predictable negative drift enables thermal error modeling in precision analog references |
| Operating Temperature | –65 °C to +150 °C - wide junction temperature range supports under-hood automotive and industrial environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBZ5232BS-7-F | Same 5.6 V nominal, but 200 mW rating and 25 Ω ZZT @ 20 mA - higher test current, lower impedance | Optimized for low-current biasing where tighter regulation at higher IZ is required | Select when lower dynamic impedance is prioritized over power handling margin |
| BZX84-B5V6,115 | 5.6 V, 300 mW, ±5% tolerance (vs. ±7.1% for BZX84C5V6), 30 Ω ZZT @ 5 mA | Tighter voltage tolerance and lower impedance, but lacks AEC-Q101 qualification | Prefer for non-automotive industrial designs requiring tighter initial VZ accuracy |
Compared with MMBZ5232BS-7-F and BZX84-B5V6,115, the BZX84C5V6-7 offers superior thermal robustness (350 mW vs. 200/300 mW), automotive qualification, and wider operating temperature range - making it optimal for high-reliability embedded power management where long-term stability and environmental resilience are critical.

FAQ
What is the maximum reverse voltage this Zener can withstand before breakdown?
The BZX84C5V6-7 has a nominal Zener voltage of 5.6 V, with a guaranteed breakdown range of 5.2 V to 6.0 V at 5 mA test current. It does not have a separate "maximum reverse voltage" rating - instead, it enters controlled Zener conduction above its specified VZ range. Sustained reverse voltage below 2.0 V yields only 1.0 µA leakage current.
Is this part suitable for use in automotive applications?
Yes - the BZX84C5V6-7 is qualified to AEC-Q101 standards and rated for operation from –65 °C to +150 °C. Its SOT23 package, lead-free plating, and green molding compound meet automotive manufacturing and reliability requirements for engine control, body electronics, and infotainment subsystems.
How does the temperature coefficient affect circuit performance?
The BZX84C5V6-7 has a temperature coefficient of –2.0 mV/°C, meaning its Zener voltage decreases by approximately 2 mV per degree Celsius rise in junction temperature. This allows predictable drift compensation in reference designs and must be factored into total error budgets for precision applications.
Can this Zener diode replace a 5.1 V or 6.2 V variant in an existing design?
No - the BZX84C5V6-7 is specifically characterized for 5.6 V regulation and cannot substitute for 5.1 V (BZX84C5V1) or 6.2 V (BZX84C6V2) parts without redesigning the bias network. Each variant has distinct VZ tolerance, ZZT, and temperature coefficient values that impact regulation accuracy and stability.
