Product details
Overview
BZX84-C8V2/LF1VL from NXP Semiconductors is a ±5 % tolerance Zener voltage regulator diode in SOT23 (TO-236AB) package, rated for 250 mW total power dissipation at 25 °C ambient, with nominal Zener voltage 8.2 V at 5 mA test current and typical differential resistance of 40 Ω. 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-C8V2/LF1VL datasheet, BZX84-C8V2/LF1VL pinout, BZX84-C8V2/LF1VL application, or BZX84-C8V2/LF1VL equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, thermal resistance data, reverse current behavior at 7.5 V, and direct substitution guidance against industry-standard alternatives.
Technical Context
This device operates as a two-terminal shunt regulator, maintaining stable output voltage by conducting reverse current above its specified breakdown threshold. Its Zener voltage exhibits a positive temperature coefficient of +3.2 mV/K at 5 mA, enabling predictable drift compensation in temperature-sensitive references.
Designed for surface-mount assembly on FR4 PCBs with single-sided copper, it supports reflow and wave soldering per JEDEC J-STD-020 and J-STD-001. The non-repetitive peak reverse power dissipation is rated at 40 W for ≤100 µs pulses, with junction-to-ambient thermal resistance of 500 K/W in free air.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 7.7 V to 8.7 V at IZ = 5 mA - defines usable regulation range under standard test conditions |
| Differential Resistance (rdiff) | 40 Ω typical at IZ = 5 mA - determines output impedance and load regulation sensitivity |
| Reverse Current (IR) | ≤0.7 µA at VR = 7.5 V - ensures minimal leakage in standby or high-impedance bias networks |
| Forward Voltage (VF) | ≤0.9 V at IF = 10 mA - enables use as low-drop rectifier or clamping diode in dual-role designs |
| Total Power Dissipation (Ptot) | 250 mW at Tamb ≤ 25 °C - sets maximum continuous DC power handling before thermal derating |
| Non-repetitive Peak Reverse Power | 40 W for tp ≤ 100 µs - supports transient overvoltage suppression in surge-prone interfaces |
| AEC-Q101 Qualified | Validated for automotive-grade reliability including HTOL, TC, and ESD testing - suitable for under-hood and infotainment systems |

FAQ
What is the Zener voltage tolerance for BZX84-C8V2/LF1VL?
The BZX84-C8V2/LF1VL has a nominal Zener voltage of 8.2 V with a tolerance of approximately ±5 %, meaning the actual breakdown voltage falls between 7.7 V and 8.7 V when tested at 5 mA. This tolerance aligns with the "C" grade designation in the BZX84 family and is confirmed in Table 8 of the NXP datasheet Rev. 6.
Is BZX84-C8V2/LF1VL qualified for automotive use?
Yes, BZX84-C8V2/LF1VL is AEC-Q101 qualified per Section 8.1 of the NXP datasheet, having passed stress tests for high-temperature operating life, temperature cycling, and electrostatic discharge. This certification validates its use in automotive powertrain, body electronics, and infotainment systems.
What is the maximum forward current rating for BZX84-C8V2/LF1VL?
The absolute maximum forward current for BZX84-C8V2/LF1VL is 200 mA, as specified in Table 5 (Limiting Values) of the NXP datasheet. However, sustained operation above 10 mA forward current is not recommended due to thermal limitations in the SOT23 package.
How does the temperature coefficient affect BZX84-C8V2/LF1VL performance?
BZX84-C8V2/LF1VL exhibits a positive temperature coefficient of +3.2 mV/K at 5 mA, meaning its Zener voltage increases by ~3.2 mV per degree Celsius rise in junction temperature. This behavior is documented in Table 8 and Figure 3 of the datasheet, enabling predictable drift compensation in reference designs.
Can BZX84-C8V2/LF1VL replace BZX84-B8V2 in an existing design?
BZX84-C8V2/LF1VL can replace BZX84-B8V2 only if the ±5 % tolerance is acceptable in place of ±2 %; the Zener voltage range expands from 7.84–8.36 V (B grade) to 7.7–8.7 V (C grade). No PCB changes are needed since both share identical SOT23 pinout and thermal characteristics.
