Product details
Overview
BZX84B6V2LT1 from onsemi is a tight-tolerance Zener diode in SOT-23 package, providing precise 6.2 V voltage regulation at 5 mA test current with ±1.9% tolerance (6.08 V to 6.32 V), 10 Ω dynamic impedance, and 3.7 pF capacitance at 0 V bias - used for reference voltage generation and overvoltage protection in space-constrained portable electronics.
For engineers reviewing the BZX84B6V2LT1 datasheet, pinout, applications, or equivalent options, key selection criteria include its ±1.9% Zener voltage tolerance, low 10 Ω Zener impedance at 5 mA, −65 °C to +150 °C operating range, and SOT-23 footprint compatibility with automated assembly processes.
Technical Context
This device operates as a two-terminal voltage reference diode, conducting in reverse breakdown to clamp or regulate voltage across a load. Its tight 6.2 V nominal Zener voltage is specified at IZT = 5 mA with temperature coefficient of +0.4 mV/°C, enabling stable performance across industrial temperature ranges.
The SOT-23 package features Pin 1 (Anode), Pin 2 (No Connection), and Pin 3 (Cathode), with polarity indicated by a band on the cathode end. It delivers 250 mW power dissipation on FR-5 board and supports ESD robustness >16 kV per Human Body Model.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84C6V2LT1G | Standard-tolerance version: ±5% (5.8–6.6 V), 10 Ω Zz, same SOT-23 package | Acceptable where cost sensitivity outweighs precision requirement; less suitable for ADC references | Select when ±5% regulation is sufficient and BOM cost reduction is prioritized |
| MMSZ4687T1G | Same 6.2 V nominal, ±5% tolerance, 10 Ω Zz, but rated for 500 mW on ceramic substrate | Higher power handling enables use in 12 V rail clamping with larger transient energy absorption | Choose for higher-power protection where thermal margin exceeds 250 mW FR-5 limit |
Compared with BZX84B6V2LT1, BZX84C6V2LT1G offers lower unit cost but sacrifices precision for general-purpose clamping, while MMSZ4687T1G trades tighter tolerance for higher power capability - making BZX84B6V2LT1 optimal for space- and accuracy-critical 6.2 V references.

FAQ
What is the Zener voltage tolerance of BZX84B6V2LT1?
The BZX84B6V2LT1 has a tight Zener voltage tolerance of ±1.9%, specified as 6.08 V minimum to 6.32 V maximum at 5 mA test current. This precision enables direct use in analog reference circuits without trimming resistors or calibration, distinguishing it from standard-tolerance variants like BZX84C6V2LT1G (±5%). The tolerance is guaranteed across the full operating temperature range.
Does BZX84B6V2LT1 have a connection on Pin 2?
No, Pin 2 of the BZX84B6V2LT1 is internally not connected (NC). The device uses only Pins 1 (Anode) and 3 (Cathode) for operation. PCB layout must leave Pin 2 unconnected - no trace, pad, or thermal relief should be attached to it. This three-pin SOT-23 configuration is standardized across the BZX84BxxxLT1G series for mechanical consistency in automated placement.
What is the maximum power dissipation of BZX84B6V2LT1 on FR-5 board?
The BZX84B6V2LT1 is rated for 250 mW total power dissipation on FR-5 board at 25 °C ambient temperature, derating linearly by 2.0 mW/°C above that point. At 85 °C ambient, usable power drops to 130 mW. This rating assumes standard JEDEC-defined board conditions (1.0 × 0.75 × 0.62 inch); performance improves on alumina substrates (300 mW).
Is BZX84B6V2LT1 suitable for automotive applications?
Yes, the BZX84B6V2LT1 meets AEC-Q101 stress test requirements for discrete semiconductors and is PPAP-capable. Its −65 °C to +150 °C junction temperature range, >16 kV HBM ESD rating, and Pb-free RoHS compliance make it qualified for under-hood and cabin electronics including engine control sensors, body controllers, and infotainment power rails - provided thermal design respects its 250 mW FR-5 power limit.
How does the temperature coefficient affect BZX84B6V2LT1 performance?
The BZX84B6V2LT1 exhibits a positive temperature coefficient of +0.4 mV/°C at 5 mA, meaning its Zener voltage increases by 0.4 mV per degree Celsius rise in junction temperature. Over a −40 °C to +125 °C range, this contributes ±66 mV drift - well within its ±1.9% tolerance band. This predictable behavior allows system designers to compensate for thermal drift in high-accuracy applications.
