Product details
Overview
BZX84-B6V2/LF1R from NXP Semiconductors is a ±2 % tolerance Zener voltage regulator diode in SOT23 (TO-236AB) package, rated for 6.2 V nominal breakdown voltage at 5 mA, 250 mW total power dissipation, and AEC-Q101 qualification for automotive use. It provides stable reference voltage in low-power supply regulation and overvoltage protection circuits.
For engineers reviewing the BZX84-B6V2/LF1R datasheet, BZX84-B6V2/LF1R pinout, BZX84-B6V2/LF1R application, or BZX84-B6V2/LF1R equivalent, key selection factors include its 6.08–6.32 V Zener voltage range, 40 Ω typical differential resistance at 5 mA, 6 µA max reverse current at 4.96 V, +0.4 to +3.7 mV/K temperature coefficient, and SOT23-compatible thermal performance on FR4 PCBs.
Technical Context
This device operates as a two-terminal passive voltage reference, conducting in reverse bias above its specified Zener voltage. Its regulation relies on controlled avalanche and Zener breakdown mechanisms, with junction temperature-dependent behavior characterized by a positive temperature coefficient (+0.4 to +3.7 mV/K) across the 5 mA test condition.
Designed for surface-mount implementation on standard FR4 PCBs, it supports reflow and wave soldering per JEDEC J-STD-020 and J-STD-002. Thermal resistance from junction to ambient is 500 K/W in free air, and junction-to-solder-point is 330 K/W - critical for derating calculations in compact layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 6.08 V min to 6.32 V max at IZ = 5 mA - defines usable regulation band under nominal test conditions |
| Differential Resistance (rdiff) | 40 Ω typ at IZ = 5 mA - determines output impedance and load regulation sensitivity |
| Reverse Current (IR) | ≤6 µA at VR = 4.96 V - ensures low leakage below regulation threshold |
| Temperature Coefficient (SZ) | +0.4 to +3.7 mV/K at IZ = 5 mA - quantifies voltage drift with junction temperature change |
| Total Power Dissipation (Ptot) | 250 mW max at Tamb ≤25 °C - sets maximum continuous DC power handling on standard PCB |
| Non-repetitive Peak Reverse Power | 40 W max for tp ≤100 µs - supports transient overvoltage clamping without failure |
| Forward Voltage (VF) | ≤0.9 V at IF = 10 mA - defines conduction loss when used in forward-biased protection paths |
Pinout & Package
SOT23 (TO-236AB) plastic surface-mounted package with 3 leads; 2.8 mm × 1.4 mm footprint, 1.1 mm height, and standard 0.95 mm lead pitch. Mounting per JEDEC MS-012.
| Pin/Terminal | Circuit Role | Design Meaning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor MMBZ5234BS-7-F | 6.2 V nominal, ±5 % tolerance, 200 mW Ptot, SOT-23 package | Higher voltage tolerance and lower power rating reduce precision and surge margin | Select when cost sensitivity outweighs regulation accuracy and transient robustness requirements |
| Vishay BZX84-C6V2-TP | 6.2 V nominal, ±5 % tolerance, 300 mW Ptot, same SOT23 footprint | Wider tolerance increases reference uncertainty; higher Ptot enables greater continuous dissipation | Choose where tighter voltage control is unnecessary but higher steady-state power handling is required |

FAQ
What is the Zener voltage tolerance of BZX84-B6V2/LF1R?
The BZX84-B6V2/LF1R has a ±2 % Zener voltage tolerance, meaning its breakdown voltage ranges from 6.08 V to 6.32 V when tested at 5 mA. This tighter tolerance compared to the ±5 % C-series variants supports more precise voltage reference and clamping applications where regulation accuracy is critical.
Is BZX84-B6V2/LF1R qualified for automotive use?
Yes, BZX84-B6V2/LF1R is AEC-Q101 qualified, having passed stress tests including temperature cycling, high-temperature reverse bias (HTRB), and electrostatic discharge per the Automotive Electronics Council standard. This makes it suitable for under-hood and cabin electronics in passenger vehicles and commercial transport systems.
What is the maximum continuous power dissipation for BZX84-B6V2/LF1R?
The BZX84-B6V2/LF1R has a maximum total power dissipation of 250 mW at ambient temperatures ≤25 °C when mounted on a standard FR4 PCB with single-sided copper. Derating is required above 25 °C, following the specified thermal resistance of 500 K/W junction-to-ambient.
How does the temperature coefficient affect BZX84-B6V2/LF1R performance?
The BZX84-B6V2/LF1R exhibits a positive temperature coefficient ranging from +0.4 to +3.7 mV/K at 5 mA, meaning its Zener voltage increases with rising junction temperature. This behavior must be accounted for in precision reference designs operating across wide temperature ranges, especially above 85 °C.
What is the pin configuration of BZX84-B6V2/LF1R in the SOT23 package?
The BZX84-B6V2/LF1R uses a 3-pin SOT23 (TO-236AB) package with Pin 1 as anode (A), Pin 2 as not connected (n.c.), and Pin 3 as cathode (K). The n.c. pin is internally isolated and must not be soldered or electrically tied to any net in layout design.
