Product details
Overview
BZX84C6V2W-7 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 and ±0.4 mV/°C temperature coefficient, used for precision voltage reference and overvoltage protection in low-power analog circuits.
For engineers reviewing the BZX84C6V2W-7 datasheet, BZX84C6V2W-7 pinout, BZX84C6V2W-7 application, or BZX84C6V2W-7 equivalent, key selection criteria include nominal Zener voltage (6.2 V), max reverse current at VR = 4.0 V (3.0 µA), thermal resistance (625 K/W), and RoHS-compliant green molding compound construction.
Technical Context
This Zener diode operates in reverse breakdown to maintain stable voltage regulation across load and line variations. Its planar die construction ensures consistent Zener characteristics, while the ultra-small SOT-323 package enables high-density PCB layouts in space-constrained applications.
It delivers specified performance at 5 mA test current (IZT), with low dynamic impedance (10 Ω) ensuring minimal voltage deviation under varying current loads, and a near-zero temperature coefficient (+0.4 mV/°C) enabling stable reference behavior over –65°C to +125°C ambient range.
Key Specifications

| Power Dissipation | 200 mW - maximum continuous power on FR4 board with recommended pad layout |
| Zener Impedance | 10 Ω @ 5 mA - low AC impedance ensures tight voltage regulation under dynamic load changes |
| Reverse Current | 3.0 µA @ 4.0 V - leakage threshold confirming sharp knee and low standby loss |
| Temp Coefficient | +0.4 mV/°C @ 5 mA - near-zero drift supports stable reference in industrial temperature range |
| Thermal Resistance | 625 K/W - junction-to-ambient value defining derating slope above 25°C ambient |
| Operating Temp | –65°C to +125°C - full specification compliance across extended industrial range |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBZ5234BS-7-F | Same 6.2 V nominal, but 350 mW rating and SOT-363 package; higher ZZT (17 Ω) | Higher power handling suits higher-current references; dual-diode package adds redundancy | Select when >200 mW dissipation or dual-Zener topology is required |
| BZX84-C6V2,315 | Identical electrical specs, but SOT-23 package (larger footprint, 350 mW rating) | SOT-23 allows easier hand-soldering and higher thermal mass for intermittent surge loads | Select when manual assembly or higher pulse power capability is prioritized over board area |
Compared with MMBZ5234BS-7-F and BZX84-C6V2,315, the BZX84C6V2W-7 offers optimal balance of ultra-compact size, industry-standard SOT-323 compatibility, and tight 10 Ω impedance-making it preferred for high-density, low-power, automated assembly environments.

FAQ
What is the maximum reverse voltage (VR) at which leakage current is specified for BZX84C6V2W-7?
The datasheet specifies 3.0 µA maximum reverse current at VR = 4.0 V. This value reflects the diode's leakage behavior below the Zener knee and is critical for low-power standby operation where quiescent current must be minimized.
Can BZX84C6V2W-7 be used in place of a 6.2 V Zener in an existing SOT-23 design?
No-it uses the smaller SOT-323 package (2.20 × 1.35 mm) versus SOT-23 (3.0 × 1.4 mm). Pad layout, solder stencil, and pick-and-place tooling require revision. Electrical specs are compatible, but mechanical fit is not interchangeable without PCB redesign.
What is the Zener test current (IZT) and why is it important for regulation accuracy?
IZT is 5.0 mA-the standardized current at which VZ (6.2 V) and ZZT (10 Ω) are measured. Operating near IZT ensures the diode remains in its specified regulation region; deviations cause measurable VZ shift due to dynamic impedance and TC effects.
Does BZX84C6V2W-7 meet automotive AEC-Q200 stress testing requirements?
No-this part is not AEC-Q200 qualified. It is rated for industrial temperature range (–65°C to +125°C) and RoHS compliance, but lacks the extended reliability testing (temperature cycling, humidity bias, etc.) required for automotive qualification.
