Product details
Overview
BZX84-C5V1/LF1VL from NXP Semiconductors is a ±5 % tolerance Zener voltage regulator diode in SOT23 (TO-236AB) package, rated for 5.1 V nominal breakdown voltage at 5 mA, 250 mW total power dissipation, and AEC-Q101 qualification for automotive use.
For engineers reviewing the BZX84-C5V1/LF1VL datasheet, BZX84-C5V1/LF1VL pinout, BZX84-C5V1/LF1VL application, or BZX84-C5V1/LF1VL equivalent, this page delivers verified electrical parameters, thermal limits, reverse current behavior at 4.8–5.4 V, differential resistance of 400–480 Ω, and temperature coefficient of −2.7 to −0.8 mV/K - all critical for precision biasing and overvoltage protection design.
Technical Context
This device operates as a two-terminal shunt regulator, maintaining stable voltage across its cathode-anode terminals under reverse-biased conditions. Its Zener breakdown mechanism provides predictable regulation with low dynamic impedance and controlled temperature drift.
Designed for surface-mount implementation on FR4 PCBs with single-sided copper, it supports pulse operation up to 40 W (100 µs, non-repetitive) and continuous ambient operation up to +150 °C. The SOT23 footprint enables high-density board layouts while meeting automotive reliability requirements per AEC-Q101.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage (VZ) | 4.8 V to 5.4 V at IZ = 5 mA - defines usable regulation window for 5.1 V nominal reference |
| Total Power Dissipation (Ptot) | 250 mW at Tamb ≤ 25 °C - sets maximum continuous DC power handling on standard PCB |
| Differential Resistance (rdif) | 400 Ω to 480 Ω at IZ = 5 mA - determines output impedance and load regulation error |
| Reverse Current (IR) | ≤ 2 µA at VR = 3 V - ensures minimal leakage in standby or sensing circuits |
| Temperature Coefficient (SZ) | −2.7 mV/K to −0.8 mV/K - quantifies voltage drift over temperature for stability-critical designs |
| Non-repetitive Peak Power (PZSM) | 40 W for tp ≤ 100 µs - supports transient overvoltage clamping without failure |
| Junction Temperature Range | −65 °C to +150 °C - enables operation in extended industrial and automotive environments |
Pinout & Package
