Product details

Overview

BZX84-A6V2,215 from Nexperia is a ±1 % tolerance Zener voltage regulator diode in SOT23 (TO-236AB) package, designed for precision low-power voltage reference and clamping in space-constrained PCBs. It delivers 6.2 V nominal breakdown voltage at 5 mA, with 150 Ω max differential resistance, 3 µA max reverse current at 4.96 V, and 0.4 mV/K temperature coefficient - enabling stable regulation in sensor biasing, power supply feedback, and overvoltage protection circuits.

For engineers reviewing the BZX84-A6V2,215 datasheet, BZX84-A6V2,215 pinout, BZX84-A6V2,215 application, or BZX84-A6V2,215 equivalent, this page provides verified electrical parameters, terminal mapping, thermal behavior under FR4 mounting, real-world use cases in analog signal conditioning and LDO feedback networks, and validated alternative parts with documented tolerance and temperature coefficient differences.

Technical Context

This Zener diode operates in reverse-biased breakdown mode to maintain a stable reference voltage across its cathode-anode terminals. Its ±1 % initial tolerance and low 0.4 mV/K temperature coefficient (at I_Z = 5 mA) minimize drift over temperature, supporting accurate voltage sensing in industrial control inputs and ADC reference buffers.

The device is rated for 250 mW total power dissipation on FR4 PCB with single-sided copper, and withstands non-repetitive 40 W reverse surges (100 µs pulse), making it suitable for transient suppression in low-energy signal paths - not primary power rail clamping.

Key Specifications

Parameter	Value and Actual Design Meaning
Breakdown Voltage V_Z	6.13 V to 6.27 V at I_Z = 5 mA - ensures tight regulation window for feedback loop stability
Differential Resistance r_dif	≤150 Ω - limits output impedance impact on reference accuracy under load variation
Reverse Current I_R	≤3 µA at V_R = 4.96 V - guarantees low leakage in high-impedance bias networks
Temperature Coefficient S_Z	+0.4 mV/K at I_Z = 5 mA - enables predictable, low-drift performance from −55 °C to +150 °C
Total Power Dissipation P_tot	250 mW at T_amb ≤ 25 °C on FR4 PCB - defines maximum continuous DC power in standard layout
Non-repetitive Peak Power	40 W (100 µs pulse) - supports ESD/transient suppression in signal-line protection
Junction Temperature Range	−55 °C to +150 °C - validates operation in extended industrial environments

Pinout & Package

SOT23 (TO-236AB) surface-mount plastic package: 3-terminal, 1.3 mm × 2.9 mm footprint, 1.1 mm height, with gull-wing leads for reflow soldering per IPC-7095 standards.

Pin/Terminal	Circuit Role	Design Meaning
1 (Anode)	Anode connection	Connected to lower-potential node; reverse-biased during regulation
2 (n.c.)	No connection	Internally unconnected; must remain floating - no PCB trace or pad required
3 (Cathode)	Cathode connection	Connected to higher-potential node; carries regulated reference voltage

Key Features

Feature	Design Value
±1 % voltage tolerance	Enables direct replacement in precision feedback loops without recalibration
Low 150 Ω dynamic impedance	Maintains <1 % output deviation under ±1 mA load current change
0.4 mV/K tempco at 5 mA	Yields <±10 mV drift over −40 °C to +85 °C ambient range
250 mW FR4-rated dissipation	Supports continuous operation at 6.2 V / 40 mA without heatsinking
40 W surge capability	Withstands IEC 61000-4-2 Level 4 contact discharge (8 kV) in series-limited paths

Applications

Industrial Sensor Biasing

LDO Feedback Reference

Use Scenario: Providing stable bias voltage to bridge-based pressure sensors in PLC analog input modules.

IC Role / Device Role / Timing Role: Zener diode acting as two-terminal shunt reference, setting common-mode voltage for instrumentation amplifier input stage.

Use Value: ±1 % V_Z tolerance and low tempco ensure sensor offset error remains <0.25 % FS over operating temperature range.

Use Scenario: Setting output voltage of adjustable low-dropout regulator (e.g., NCP1117) in embedded microcontroller power supply.

IC Role / Device Role / Timing Role: Shunt reference connected between ADJ and OUT pins to define regulated output via resistor divider ratio.

Use Value: 150 Ω r_dif minimizes regulation error caused by divider current mismatch, improving load regulation to ±0.5 %.

Overvoltage Clamp for MCU I/O

ADC Reference Stabilization

Use Scenario: Protecting 3.3 V GPIO pins of ARM Cortex-M0+ microcontrollers against 5 V bus coupling transients.

IC Role / Device Role / Timing Role: Cathode tied to I/O line, anode to ground - clamps excursions above 6.2 V while limiting peak current to safe levels.

Use Value: 40 W non-repetitive surge rating absorbs 100 µs transients up to 6.2 V × 6.45 A without degradation.

Use Scenario: Supplying clean 6.2 V reference to SAR ADC (e.g., ADS7822) in battery-powered data loggers.

IC Role / Device Role / Timing Role: Low-noise shunt reference decoupled with 100 nF ceramic capacitor, replacing higher-cost bandgap ICs where 0.1 % absolute accuracy is unnecessary.

Use Value: 3 µA max I_R at 4.96 V prevents loading of high-impedance divider networks feeding ADC REF+ pin.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
BZX84-B6V2,215	±2 % tolerance (6.08 V–6.32 V), +1.2 mV/K tempco	Higher voltage drift over temperature; acceptable where calibration compensates for offset	Select when cost sensitivity outweighs need for tight tempco and tighter initial tolerance
MMBZ5234B-7-F	±5 % tolerance (5.89 V–6.51 V), 200 Ω r_dif, +2.5 mV/K tempco	Reduced regulation accuracy and higher impedance limit use in precision feedback	Choose only for non-critical clamping where 6.2 V nominal is sufficient and board space allows larger SOT23 variant

Compared with BZX84-A6V2,215, the BZX84-B6V2,215 trades 1 % tolerance and 0.8 mV/K lower tempco for lower unit cost, while MMBZ5234B-7-F sacrifices both accuracy and thermal stability for broader availability - making the A-grade part optimal for closed-loop regulation where long-term drift must be minimized.

FAQ

What is the maximum continuous forward current for BZX84-A6V2,215?

The device is not rated for continuous forward conduction; its design purpose is reverse-bias Zener operation. Absolute maximum forward current is 200 mA per limiting values table, but sustained forward bias degrades regulation performance and is not recommended in functional circuits.

Can BZX84-A6V2,215 replace a 6.2 V TL431-based reference?

No - the TL431 is an adjustable shunt regulator with active feedback, offering 0.5 % initial accuracy and 30 ppm/°C tempco. BZX84-A6V2,215 is a passive two-terminal Zener with fixed 6.2 V output and higher tempco; it lacks the precision, programmability, and sink-current capability of the TL431.

Is pin 2 (n.c.) required to be left unconnected on the PCB?

Yes - pin 2 is internally not connected and must remain electrically floating. No trace, pad, or solder mask opening should be assigned to it; including it in routing risks mechanical stress or unintended parasitic coupling in high-frequency layouts.

How does thermal resistance affect regulation accuracy at elevated ambient temperatures?

With R_th(j-a) = 500 K/W, a 100 mW dissipation raises junction temperature by 50 °C above ambient. Since tempco is +0.4 mV/K, this induces ~20 mV (0.32 %) V_Z shift - a key factor in high-temperature industrial designs where derating or forced airflow may be needed.
