Product details
Overview
BZX84C5V6-7-F from Diodes Incorporated is a 5.6 V, 350 mW surface-mount Zener diode in SOT23 package, rated for 5 mA test current with 40 Ω dynamic impedance at 1 kHz and ±2.0% voltage tolerance (5.2–6.0 V), used for precision voltage regulation and overvoltage protection in low-power analog circuits.
For engineers reviewing the BZX84C5V6-7-F datasheet, BZX84C5V6-7-F pinout, BZX84C5V6-7-F application, or BZX84C5V6-7-F equivalent, key selection criteria include zener voltage accuracy, thermal resistance (357 °C/W), reverse leakage (≤1.0 µA at 2.0 V), temperature coefficient (−2.0 mV/°C), and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This Zener diode operates in reverse breakdown to maintain stable reference voltage under varying load and temperature conditions. Its planar die construction ensures consistent breakdown characteristics and low leakage, with a nominal zener voltage of 5.6 V at 5 mA test current and a negative temperature coefficient of −2.0 mV/°C.
The device delivers 350 mW power dissipation when leads are held at ambient temperature, and its thermal resistance of 357 °C/W (junction-to-ambient) supports reliable operation in compact PCB layouts. It is fully RoHS-compliant, halogen- and antimony-free, and qualified to AEC-Q101 for high-reliability automotive applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 5.6 V nominal, 5.2–6.0 V range at 5 mA - defines precise clamping threshold for voltage reference or protection |
| Power Dissipation (PD) | 350 mW - maximum continuous power at ambient-temperature terminals, enabling use in space-constrained designs |
| Zener Impedance (ZZT) | 40 Ω at 1 kHz, 5 mA - low dynamic resistance ensures minimal output voltage variation under load transients |
| Reverse Leakage (IR) | ≤1.0 µA at VR = 2.0 V - ultra-low leakage preserves signal integrity in high-impedance bias networks |
| Temperature Coefficient | −2.0 mV/°C - predictable voltage drift enables accurate thermal compensation in reference circuits |
| Package | SOT23 - industry-standard 3-pin surface-mount footprint compatible with automated pick-and-place assembly |
| AEC-Q101 Qualified | Yes - validated for automotive electronics requiring extended temperature range (−65 to +150 °C) and reliability |
Pinout & Package
Package: SOT23 - molded plastic case, UL 94V-0 flammability rating, matte tin-plated alloy 42 leadframe, polarity indicated by cathode band on top view.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Pin 1) | Forward conduction terminal | Connected to lower-potential node in reverse-biased configuration; required for proper Zener operation |
| Cathode (Pin 2) | Zener breakdown terminal | Connected to higher-potential node; carries regulated voltage during reverse conduction |
| NC / Dummy (Pin 3) | Non-connected internal tie | Electrically isolated; serves mechanical support only - must not be connected in circuit layout |
Key Features
| Feature | Design Value |
|---|---|
| Planar die construction | Ensures tight parametric distribution and repeatable breakdown behavior across production lots |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBZ5232B-7-F | Same 5.6 V nominal, but 225 mW rating and 30 Ω ZZT; no AEC-Q101 qualification | Limited to commercial-grade consumer electronics; unsuitable for automotive or industrial environments | Select when cost is primary constraint and thermal derating allows 225 mW operation |
| BZX84-B5V6,115 | 5.6 V, 300 mW, 40 Ω ZZT, but only RoHS-compliant (not halogen-free); JEDEC TO-236AB package | Higher thermal resistance (417 °C/W) and larger footprint reduce suitability for dense portable PCBs | Prefer where legacy TO-236AB compatibility is required and green compliance is not mandated |
Compared with MMBZ5232B-7-F and BZX84-B5V6,115, the BZX84C5V6-7-F provides superior automotive qualification, lower thermal resistance, and stricter environmental compliance-making it the optimal choice for next-generation automotive and medical wearables where reliability and regulatory alignment are non-negotiable.

FAQ
What is the maximum reverse voltage this Zener can withstand before breakdown?
The BZX84C5V6-7-F has a nominal zener voltage of 5.6 V at 5 mA test current, with a guaranteed breakdown range of 5.2 V to 6.0 V. It is not rated for forward conduction beyond 0.9 V at 10 mA, and sustained reverse voltage below 5.2 V will result in negligible current flow (<1.0 µA at 2.0 V).
Is this part suitable for use in automotive applications?
Yes - the BZX84C5V6-7-F is explicitly qualified to AEC-Q101 standards, with operating temperature range from −65 °C to +150 °C, halogen- and antimony-free "Green" construction, and moisture sensitivity level 1, making it approved for under-hood and cabin electronics including body control modules and ADAS sensors.
How does the temperature coefficient affect voltage stability?
This device has a temperature coefficient of −2.0 mV/°C, meaning its zener voltage decreases by 2 mV per degree Celsius rise in junction temperature. At 125 °C ambient (with self-heating), the shift remains within ±0.15 V of nominal - acceptable for most reference and protection roles where absolute accuracy is secondary to clamping consistency.
Can Pin 3 be left unconnected or must it be grounded?
Pin 3 is a non-connected (NC) internal tie with no electrical function. It must remain unconnected in the PCB layout - grounding or routing to any net may cause mechanical stress or unintended coupling. The SOT23 pinout requires only Pins 1 (anode) and 2 (cathode) to be routed per the top-view schematic in DS18001 Rev. 33-2.
