Product details
Overview
BZX84-C6V2/LF1VL from NXP Semiconductors is a 6.2 V ±5 % tolerance Zener voltage regulator diode in SOT23 (TO-236AB) package, rated for 250 mW total power dissipation at 25 °C ambient, with 6 Ω typical differential resistance at 5 mA and 4 µA maximum reverse current at 4.96 V. It serves as a precision reference or low-power voltage clamp in power supply feedback paths and signal-level regulation circuits.
For engineers reviewing the BZX84-C6V2/LF1VL datasheet, BZX84-C6V2/LF1VL pinout, BZX84-C6V2/LF1VL application, or BZX84-C6V2/LF1VL equivalent, key selection criteria include its ±5 % tolerance, AEC-Q101 qualification for automotive use, 6.2 V nominal Zener voltage, thermal resistance of 500 K/W (junction-to-ambient), and non-repetitive peak reverse power capability of 40 W.
Technical Context
This device operates as a two-terminal silicon Zener diode, conducting in reverse breakdown to maintain stable voltage across its terminals under defined current conditions. Its regulation behavior is defined by Zener voltage (VZ = 5.8–6.6 V), differential resistance (rdif ≤ 150 Ω), and temperature coefficient (+0.4 to +3.7 mV/K).
Designed for surface-mount implementation on FR4 PCBs with single-sided copper, it supports operation from −65 °C to +150 °C junction temperature and meets AEC-Q101 stress qualification for discrete semiconductors, confirming suitability for automotive-grade voltage reference applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 5.8 V to 6.6 V at IZ = 5 mA - defines usable regulation range under standard test condition |
| Tolerance | ±5 % - specifies maximum deviation from nominal 6.2 V value in production units |
| Total Power Dissipation (Ptot) | 250 mW at Tamb ≤ 25 °C - sets maximum continuous DC power handling on standard PCB |
| Differential Resistance (rdif) | 40 Ω typical at IZ = 5 mA - determines output impedance and load regulation sensitivity |
| Reverse Current (IR) | ≤ 4 µA at VR = 4.96 V - indicates leakage level below breakdown, critical for low-power bias networks |
| Non-repetitive Peak Reverse Power (PZSM) | 40 W for tp ≤ 100 µs - enables transient overvoltage clamping without damage |
| Junction-to-Ambient Thermal Resistance (Rth(j-a)) | 500 K/W - quantifies self-heating rise per watt on standard FR4 layout |

FAQ
What is the Zener voltage tolerance for BZX84-C6V2/LF1VL?
The BZX84-C6V2/LF1VL has a nominal Zener voltage of 6.2 V with a tolerance of approximately ±5 %, meaning its actual breakdown voltage falls within the 5.8 V to 6.6 V range when tested at 5 mA. This tolerance is confirmed in Table 8 of the NXP datasheet Rev. 6 and applies specifically to the "C" variant of the BZX84 series.
Is BZX84-C6V2/LF1VL qualified for automotive use?
Yes, BZX84-C6V2/LF1VL is AEC-Q101 qualified per Section 8.1 of the NXP datasheet Rev. 6, confirming its suitability for automotive applications including engine control, body electronics, and ADAS subsystems. The qualification covers stress testing for temperature cycling, humidity, and mechanical robustness.
What is the maximum reverse current for BZX84-C6V2/LF1VL at 4.96 V?
At a reverse voltage of 4.96 V (80 % of nominal VZ), the BZX84-C6V2/LF1VL exhibits a maximum reverse current (IR) of 4 µA, as specified in Table 8 of the NXP datasheet Rev. 6. This low leakage supports stable operation in high-impedance bias networks.
Does BZX84-C6V2/LF1VL have a connected pin 2?
No, pin 2 of BZX84-C6V2/LF1VL is internally not connected (n.c.), as documented in Table 2 (Pinning) of the NXP datasheet Rev. 6. It must remain unconnected on the PCB layout to avoid unintended parasitic coupling or thermal path interference.
What is the thermal resistance from junction to ambient for BZX84-C6V2/LF1VL?
The junction-to-ambient thermal resistance (Rth(j-a)) for BZX84-C6V2/LF1VL is 500 K/W under standard test conditions: mounted on FR4 PCB with single-sided copper, tin-plated, and standard footprint (Table 6, NXP datasheet Rev. 6). This value governs temperature rise under continuous DC power dissipation.
