Product details
Overview
BZX84C6V2W-7-F from Diodes Incorporated is a 6.2 V, 200 mW surface-mount Zener diode in SOT-323 package, rated for 5 mA test current with 10 Ω dynamic impedance at 1 kHz and ±0.4 to +3.7 mV/°C temperature coefficient; used for precision voltage reference and overvoltage protection in low-power analog sensor interfaces.
For engineers reviewing the BZX84C6V2W-7-F datasheet, BZX84C6V2W-7-F pinout, BZX84C6V2W-7-F application, or BZX84C6V2W-7-F equivalent, key selection criteria include zener voltage tolerance (5.8–6.6 V), reverse leakage at 4.0 V (≤3.0 µA), thermal resistance (625 K/W), and RoHS-compliant green molding compound compatibility with reflow soldering profiles.
Technical Context
This Zener diode operates in reverse breakdown mode with tightly controlled nominal voltage of 6.2 V at 5 mA test current, exhibiting low dynamic impedance (10 Ω at 1 kHz) and stable temperature coefficient (0.4 to 3.7 mV/°C). Its planar die construction ensures repeatable breakdown characteristics across production lots.
The device is optimized for low-power regulation and clamping in space-constrained PCB layouts, leveraging SOT-323's ultra-small footprint (2.2 × 1.35 × 0.9 mm) and thermal performance on FR4 boards with recommended pad layout. It supports continuous operation from –65 °C to +125 °C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 6.2 V nominal, 5.8–6.6 V min/max at IZT = 5 mA - defines precise clamping threshold for 5 V rail protection |
| Power Dissipation (PD) | 200 mW at TA = 25 °C - limits maximum continuous power in ambient conditions without derating |
| Zener Impedance (ZZT) | 10 Ω at f = 1 kHz - ensures minimal voltage shift under small-signal AC load variations |
| Reverse Leakage (IR) | ≤3.0 µA at VR = 4.0 V - guarantees low standby current in voltage-sense circuits |
| Temp. Coefficient (αVZ) | +0.4 to +3.7 mV/°C at IZT = 5 mA - enables predictable drift compensation in temperature-stable references |
| Package | SOT-323 - 3-terminal surface-mount outline (2.2 × 1.35 × 0.9 mm) compatible with standard pick-and-place and reflow |
| RoHS Compliance | Lead-free, "Green" molding compound (halogen-free), UL 94V-0 rated - meets industrial and consumer environmental requirements |
Pinout & Package
Package: SOT-323 - ultra-small plastic surface-mount case with gull-wing leads; dimensions: 2.20 mm length × 1.35 mm width × 0.90 mm height; moisture sensitivity level 1 per J-STD-020D.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Pin 1) | Forward conduction terminal / cathode reference ground | Connected to system ground or lower-potential node when used in reverse-biased regulation |
| Cathode (Pin 2) | Zener breakdown terminal / voltage clamp input | Receives input voltage to be regulated; clamps to 6.2 V above anode potential during overvoltage events |
| Collector / Heat Sink (Pin 3) | Thermal path / mechanical anchor | Not electrically active; provides mechanical stability and minor thermal dissipation via PCB copper pour |
Key Features
| Feature | Design Value |
|---|---|
| Planar die construction | Ensures consistent Zener voltage distribution and long-term parametric stability across temperature and life cycles |
| 200 mW power rating | Supports reliable operation in battery-powered sensors and low-current bias networks without thermal runaway risk |
| Ultra-small SOT-323 package | Enables placement in high-density layouts such as wearables and IoT edge nodes where board area is constrained |
| Low 10 Ω Zener impedance | Maintains <±10 mV output variation under ±1 mA load transients-critical for ADC reference buffering |
| Halogen-free "Green" compound | Meets IPC-1752A material declaration requirements and eliminates antimony trioxide flame retardants |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBZ5234BS-7-F | Zener voltage 6.0 V (5.7–6.3 V), 350 mW rating, SOT-323 package, 15 Ω ZZT | Higher power handling but looser voltage tolerance and higher impedance - suitable for less critical clamping | Select when higher surge energy absorption is needed and ±5% voltage accuracy is acceptable |
| BZX84-C6V2,115 | Same 6.2 V spec, but in SOT-23 package (larger footprint, 350 mW rating, 10 Ω ZZT) | Greater thermal mass and power margin, but occupies 2.9 × 1.3 × 1.1 mm vs. SOT-323's 2.2 × 1.35 × 0.9 mm | Choose when board layout allows larger package and higher reliability margin under sustained 150 °C ambient |
Compared with MMBZ5234BS-7-F and BZX84-C6V2,115, the BZX84C6V2W-7-F delivers tighter voltage tolerance (±0.4 V), lower profile (0.9 mm height), and halogen-free compliance-making it optimal for miniaturized, environmentally regulated designs where precision and footprint dominate.

FAQ
What is the maximum reverse voltage this Zener can withstand before breakdown?
The BZX84C6V2W-7-F has a nominal Zener voltage of 6.2 V at 5 mA test current, with guaranteed breakdown occurring between 5.8 V and 6.6 V. It is not rated for continuous reverse voltage above its specified VZ range; operation beyond 6.6 V risks exceeding 200 mW power limit unless current is strictly limited by external series resistance.
Can this part be used in place of a 5.1 V Zener for logic-level shifting?
No-this device is a 6.2 V Zener and will not regulate at 5.1 V. Substituting it for a 5.1 V part would result in incorrect clamping voltage, potentially damaging downstream 5 V logic inputs. Use BZX84C5V1W-7-F instead, which is specified for 4.8–5.4 V at 5 mA.
Is the SOT-323 package compatible with standard reflow soldering profiles?
Yes-the SOT-323 package is qualified for lead-free reflow per JEDEC J-STD-020D Level 1, with peak temperature up to 260 °C. Its matte tin finish and green molding compound ensure reliable wetting and intermetallic formation without voiding or delamination under standard Pb-free thermal profiles.
Does this Zener diode have polarity marking on the package?
Yes-the SOT-323 package uses a molded cathode band (visible as a faint line near Pin 2) and laser-marked "KR4" code on the top surface. The cathode (Pin 2) must connect to the higher-potential node in reverse-bias configuration; incorrect orientation results in forward conduction at ~0.9 V instead of Zener regulation.
