Product details
Overview
BZX84C6V2ET1G from onsemi is a 6.2 V, 250 mW surface-mount Zener diode in SOT-23 package, designed for precision voltage regulation and reference in space-constrained circuits. It delivers ±0.4 V tolerance at 5 mA test current, 10 Ω dynamic impedance, and operates across −65 °C to +150 °C junction temperature range. It is used in overvoltage protection, power supply feedback loops, and voltage clamping in portable electronics.
For engineers reviewing the BZX84C6V2ET1G datasheet, pinout, applications, or equivalent options, key selection criteria include Zener voltage accuracy (5.8–6.6 V), low dynamic impedance (10 Ω @ 5 mA), ESD robustness (>16 kV HBM), thermal resistance (500 °C/W on FR-5), and Pb-free SOT-23 compatibility with automated assembly.
Technical Context
This device functions as a two-terminal voltage reference where reverse-biased operation establishes a stable breakdown voltage. Its Zener mechanism provides predictable regulation under controlled current conditions, with temperature coefficient of +3.7 mV/°C enabling predictable drift compensation in mid-voltage designs.
The SOT-23 package features an anode (Pin 1), no-connection terminal (Pin 2), and cathode (Pin 3), supporting unidirectional clamping and simple integration into feedback paths. Its 225 W peak pulse rating (8 × 20 µs) supports transient suppression without external components.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 5.8–6.6 V @ IZT = 5 mA - defines regulated output range for feedback or clamp design |
| Power Dissipation | 250 mW on FR-5 board - sets maximum continuous DC power handling in standard PCB layout |
| Zener Impedance (ZZT) | 10 Ω @ 5 mA - determines output voltage stability under load variation |
| Reverse Leakage (IR) | 3.0 µA @ VR = 4.0 V - specifies minimum off-state current in clamping configuration |
| Capacitance (C) | 185 pF @ VR = 0 V, f = 1 MHz - impacts high-frequency noise filtering and signal integrity |
| Temperature Coefficient | +3.7 mV/°C @ 5 mA - enables predictable voltage drift modeling across operating temperature |
| ESD Rating | Class 3 (>16 kV HBM) - ensures robustness against handling and system-level electrostatic discharge |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMSZ4688T1G | 6.2 V nominal, 500 mW rating, 15 Ω ZZT, SOD-123 package (larger footprint) | Higher power handling but requires more PCB area; less suitable for ultra-dense layouts | Choose when higher continuous power dissipation (>250 mW) is needed and board space permits larger package. |
| BZX84-C6V2,215 | Same 6.2 V spec, 250 mW, but in legacy SOT-23 with RoHS-compliant but non-Pb-free plating | Not qualified for new automotive designs requiring AEC-Q101; lacks Class 3 ESD rating | Acceptable only for cost-sensitive industrial prototypes where Pb-free and high ESD immunity are not mandated. |
Compared with MMSZ4688T1G and BZX84-C6V2,215, the BZX84C6V2ET1G offers optimal balance of compact SOT-23 size, Pb-free compliance, Class 3 ESD robustness, and tight 10 Ω impedance-making it preferred for new portable, automotive, and high-reliability designs.

FAQ
What is the Zener voltage tolerance of BZX84C6V2ET1G at 5 mA test current?
The BZX84C6V2ET1G has a specified Zener voltage range of 5.8 V to 6.6 V at IZT = 5 mA, corresponding to a nominal 6.2 V with ±0.4 V absolute tolerance. This tolerance is verified per onsemi's Electrical Characteristics table and supports designs requiring stable regulation within ±6.5% of nominal value without trimming.
Does BZX84C6V2ET1G have a no-connect pin, and how should it be handled on the PCB?
Yes, BZX84C6V2ET1G has Pin 2 designated as "No Connection" per its mechanical outline and marking diagram. This terminal is internally isolated and must remain unconnected on the PCB layout. Routing traces to or placing solder paste on Pin 2 may cause parasitic coupling or reliability issues and violates onsemi's recommended assembly practice.
What is the maximum allowable soldering temperature and duration for BZX84C6V2ET1G?
The maximum case temperature for soldering BZX84C6V2ET1G is 260 °C for up to 10 seconds, as specified in the Mechanical Characteristics section. This limit applies to both wave and reflow processes and ensures integrity of the void-free thermosetting plastic case and corrosion-resistant finish without delamination or plating degradation.
Is BZX84C6V2ET1G suitable for automotive applications, and what qualification does it hold?
BZX84C6V2ET1G is not AEC-Q101 qualified; only the SZ-prefix variants (e.g., SZBZX84C6V2ET1G) meet automotive requirements. The "ET1G" suffix indicates commercial-grade, Pb-free, RoHS-compliant construction. For automotive use, engineers must select the SZBZX84C6V2ET1G variant, which includes PPAP capability and site-specific process controls.
How does the temperature coefficient of BZX84C6V2ET1G affect its performance across −40 °C to +85 °C?
The BZX84C6V2ET1G exhibits a +3.7 mV/°C temperature coefficient at IZT = 5 mA. Over a 125 °C span (−40 °C to +85 °C), this results in approximately ±232 mV total drift from nominal 6.2 V-well within its 5.8–6.6 V specification window. This positive TC enables predictable compensation when paired with negative-TC components in reference circuits.
