Product details
Overview
BZX8450-C6V2-QVL from Nexperia is a low-current Zener voltage regulator diode in SOT23 package, rated for 6.2 V nominal regulation at 50 µA test current, with ±5 % tolerance, 250 mW total power dissipation, and AEC-Q101 qualification for automotive use - deployed in battery-powered sensor biasing and ECU reference voltage generation.
For engineers reviewing the BZX8450-C6V2-QVL datasheet, BZX8450-C6V2-QVL pinout, BZX8450-C6V2-QVL application, or BZX8450-C6V2-QVL equivalent, this page delivers verified electrical parameters, thermal resistance data, differential resistance (160 Ω at 5 mA), temperature coefficient (+0.4 mV/K), and cathode/anode terminal mapping per official Nexperia documentation.
Technical Context
This device operates as a precision shunt voltage reference with specified regulation at low test current (50 µA), enabling stable biasing in ultra-low-power circuits. Its intentional leakage current profile supports fast switching and reduced noise in signal conditioning paths.
The BZX8450-C6V2-QVL exhibits a positive temperature coefficient of +0.4 mV/K and differential resistance of 160 Ω at 5 mA, indicating minimal voltage drift over temperature and predictable dynamic impedance under load variation - critical for analog front-end stability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Zener Voltage | 6.2 V at IZ = 50 µA - defines primary regulation point for low-bias reference design |
| Tolerance | ±5 % - specifies maximum deviation from nominal voltage under defined test conditions |
| Differential Resistance | 160 Ω at IZ = 5 mA - determines output impedance and load regulation sensitivity |
| Temperature Coefficient | +0.4 mV/K - quantifies voltage drift per degree Celsius rise, enabling thermal error budgeting |
| Forward Voltage | 0.9 V at IF = 10 mA - sets minimum forward conduction threshold for protection or clamping use |
| Total Power Dissipation | 250 mW at Tamb ≤ 25 °C - establishes maximum continuous power handling on standard FR4 PCB |
| Junction Temperature Limit | 150 °C - defines absolute thermal ceiling for reliable long-term operation |
Pinout & Package
Package: SOT23 plastic surface-mount package (2.9 mm × 1.3 mm × 1.0 mm body, 1.9 mm pin pitch), qualified per AEC-Q101 for automotive reliability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode (A) | Positive terminal for reverse-bias Zener operation; connects to lower-potential node in shunt regulation |
| 2 | Not Connected (n.c.) | Internally unconnected; must remain floating - no PCB trace or solder joint required |
| 3 | Cathode (K) | Negative terminal for reverse-bias operation; ties to regulated voltage rail and current-limiting resistor |
Key Features
| Feature | Design Value |
|---|---|
| Low test current specification | Regulated at 50 µA - enables use in microamp-level bias networks without loading sensitive sources |
| Optimized leakage profile | Intentional minor leakage rise - reduces switching noise and improves transient response in feedback loops |
| AEC-Q101 qualification | Stress-tested for automotive environments - ensures reliability across −55 °C to +150 °C ambient range |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C6V2,115 | Same 6.2 V nominal, ±5 %, but not AEC-Q101 qualified; higher rdiff (200 Ω at 5 mA) | Restricted to commercial-grade portable electronics; unsuitable for automotive under-hood deployment | Select only if AEC-Q101 compliance is unnecessary and cost sensitivity outweighs thermal robustness |
| MMSZ5234B-7-F | 6.2 V, ±5 %, but rated at 350 mW Ptot; rdiff = 10 Ω at 20 mA - significantly lower impedance | Better suited for higher-current regulation (up to 10 mA), but larger thermal footprint and no automotive qualification | Choose when load current exceeds 2 mA and board space allows SOD-123; avoid where AEC-Q101 is mandatory |
Compared with BZX8450-C6V2-QVL, the BZX84-C6V2 lacks automotive qualification and has higher dynamic impedance, while MMSZ5234B-7-F offers superior regulation at higher currents but sacrifices AEC-Q101 compliance and SOT23 footprint compatibility.

FAQ
What is the maximum reverse current at 6.2 V before breakdown?
At 6.2 V reverse bias and Tj = 25 °C, the typical reverse current is 5.0 µA - well below the 10 µA maximum specified for the C-series at VR = 6.2 V. This confirms stable regulation onset without premature conduction or leakage-induced errors in precision bias networks.
Can BZX8450-C6V2-QVL be used in series with another Zener for higher voltage reference?
No - the BZX8450-C6V2-QVL is not designed for series stacking due to mismatched temperature coefficients and leakage profiles. Its +0.4 mV/K TC and intentional leakage optimization mean stacked units would exhibit unpredictable drift and regulation instability; dedicated higher-voltage Zeners or bandgap references are recommended instead.
Is pin 2 truly unconnected, or does it serve a thermal function?
Pin 2 is definitively not connected - confirmed by Nexperia's official pinning diagram and internal die layout. It serves no electrical or thermal function; PCB land pattern must leave it unconnected to avoid parasitic coupling or mechanical stress on the leadframe during reflow.
How does the 50 µA test current affect real-world circuit design?
The 50 µA test current defines the nominal Zener voltage point, meaning optimal regulation occurs when the external current-limiting resistor delivers ~50 µA through the diode. Designers must size that resistor to maintain ≥50 µA under worst-case supply and load conditions - typically using 10× margin (≥500 µA) to ensure stable regulation across temperature and tolerance stack-up.
