Product details

Overview

BZX84-C6V2/DG/B3:2 from Nexperia is a 6.2 V, 250 mW surface-mount Zener diode in SOT-23 package with ±5% tolerance, 100 nA maximum reverse leakage at 4 V, and 15 Ω dynamic impedance at 5 mA, used for voltage regulation and overvoltage protection in low-power analog circuits.

For engineers reviewing the BZX84-C6V2/DG/B3:2 datasheet, BZX84-C6V2/DG/B3:2 pinout, BZX84-C6V2/DG/B3:2 application, or BZX84-C6V2/DG/B3:2 equivalent, key selection criteria include Zener voltage accuracy, power dissipation limit, thermal resistance, reverse leakage behavior, and SOT-23 footprint compatibility with automated assembly.

Technical Context

This Zener diode operates in reverse breakdown to maintain a stable reference voltage across its terminals under varying load and supply conditions. It is characterized at test current I_Z = 5 mA and supports continuous DC operation up to 250 mW at T_amb = 25 °C.

The device exhibits a nominal Zener voltage of 6.2 V with tight ±5% tolerance, low dynamic impedance (15 Ω), and guaranteed reverse leakage ≤100 nA at 4 V - enabling precise clamping and low-error voltage referencing in signal conditioning paths.

Key Specifications

Parameter	Value and Actual Design Meaning
Zener Voltage (V_Z)	6.2 V ±5% - defines clamping threshold for overvoltage protection and reference stability in bias networks.
Power Dissipation (P_tot)	250 mW at T_amb = 25 °C - sets maximum continuous DC power handling without derating.
Dynamic Impedance (Z_Z)	15 Ω at I_Z = 5 mA - determines voltage regulation sensitivity to current variation.
Reverse Leakage (I_R)	≤100 nA at V_R = 4 V - ensures minimal parasitic loading on high-impedance nodes.
Package	SOT-23 - enables 0.95 mm pitch pick-and-place assembly and thermal performance suitable for low-power PCB layouts.
Thermal Resistance (R_thJA)	470 K/W - quantifies junction-to-ambient heat transfer limitation in still air.

Pinout & Package

SOT-23 package with three terminals: anode (pin 1), cathode (pin 2), and unused terminal (pin 3) - standard configuration for single Zener diodes in this series.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1	Anode	Connected to lower-potential node; reverse-biased during Zener operation.
Pin 2	Cathode	Connected to higher-potential node; defines polarity for breakdown conduction.
Pin 3	No Connection	Internally unconnected; must remain floating per datasheet layout guidance.

Key Features

Feature	Design Value
Tight voltage tolerance	±5% at 6.2 V enables accurate reference generation without post-calibration.
Low dynamic impedance	15 Ω at 5 mA ensures <10 mV output shift per 150 µA load change.
Guaranteed low leakage	≤100 nA at 4 V prevents signal distortion in microamp-level sensor interfaces.
SOT-23 footprint	Standardized 3-pin package supports automated optical inspection and reflow compatibility.

Applications

Use Scenario: Clamping 3.3 V or 5 V logic rails against transient overvoltage events in industrial I/O modules.

IC Role / Device Role / Timing Role: Zener diode acting as shunt regulator to divert excess current when rail exceeds 6.2 V.

Use Value: Prevents latch-up or damage to downstream logic ICs by limiting peak voltage to 6.5 V (6.2 V + 5% tolerance).

Use Scenario: Providing stable reference voltage for 12-bit SAR ADCs in battery-powered data loggers.

IC Role / Device Role / Timing Role: Low-leakage Zener supplying reference node with minimal current draw and drift.

Use Value: Enables ≤0.5 LSB reference error contribution due to Zener voltage stability and low temperature coefficient.

Equivalent & Alternatives

The following parts are listed as comparable options for similar Zener regulation applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
MMSZ4686-7-F	Same 6.2 V ±5%, but rated 350 mW and uses SOD-123 package.	Higher power handling suits higher-current clamp circuits; larger footprint limits dense PCB layouts.	Select when >250 mW dissipation or improved thermal margin is required.
BZX84-C6V2,115	Identical electrical specs and SOT-23 package, but different tape-and-reel packaging code.	No functional difference; compatible in all circuit and assembly contexts.	Preferred for direct drop-in replacement where packaging logistics align with existing line setup.

Compared with MMSZ4686-7-F and BZX84-C6V2,115, the BZX84-C6V2/DG/B3:2 offers optimized cost-per-unit in high-volume SMT production while maintaining identical regulation performance and board space efficiency.

FAQ

What is the maximum reverse voltage before breakdown for BZX84-C6V2/DG/B3:2?

The nominal Zener voltage is 6.2 V with ±5% tolerance, meaning breakdown occurs between 5.89 V and 6.51 V at I_Z = 5 mA. The device is not rated for sustained reverse voltage below this range - it remains non-conductive until reaching the specified V_Z threshold under defined test conditions.

Can BZX84-C6V2/DG/B3:2 be used in place of a 5.6 V Zener diode?

No - substituting a 6.2 V Zener for a 5.6 V part changes the clamping or reference voltage by 10.7%, which exceeds typical system tolerances. This may cause improper reset timing, ADC reference error, or insufficient overvoltage margin depending on circuit function and supply headroom.

Is the third pin in the SOT-23 package electrically connected?

No - pin 3 is internally unconnected (NC) and must remain floating in PCB layout. Routing or soldering to pin 3 violates the device's thermal and electrical specifications and may cause inconsistent Zener behavior or premature failure under thermal stress.

How does ambient temperature affect the Zener voltage of this device?

The BZX84-C6V2/DG/B3:2 has a typical temperature coefficient of +2.5 mV/°C near 6.2 V. Over a –55 °C to +150 °C range, V_Z shifts approximately ±250 mV - a ±4% deviation relative to nominal. Designers must account for this drift in precision reference applications using temperature compensation or calibration.
