Product details
Overview
BZX8850-C2V4YL from Nexperia is a low-current Zener diode in SOD882 (DFN1006-2) package, designed for precision voltage regulation at 2.4 V nominal with ±2 % tolerance. It delivers stable reference voltage at 50 µA test current, exhibits 200 mΩ typical differential resistance at 5 mA, and supports ambient temperatures from −55 °C to +150 °C - ideal for battery-powered sensor biasing and low-power microcontroller reset circuits.
For engineers reviewing the BZX8850-C2V4YL datasheet, BZX8850-C2V4YL pinout, BZX8850-C2V4YL application, or BZX8850-C2V4YL equivalent, this page provides verified Zener voltage, thermal resistance, leakage behavior, and SOD882 footprint compatibility for compact PCB design and low-bias analog signal conditioning.
Technical Context
This Zener diode operates in reverse breakdown mode with a nominal Zener voltage of 2.4 V at IZ = 50 µA, maintaining tight ±2 % tolerance across temperature. Its low test current enables minimal quiescent power draw, critical for energy-constrained systems.
The device features a cathode-anode two-terminal structure in a leadless DFN1006-2 package, with thermal resistance Rth(j-a) = 500 K/W on FR4 PCB. It exhibits 200 µA max reverse leakage at VR = 1.0 V and 0.9 V max forward voltage at 10 mA, supporting bidirectional voltage clamping and low-drop rectification roles.
Key Specifications

FAQ
What is the maximum reverse leakage current for BZX8850-C2V4YL at 1.0 V?
The maximum reverse leakage current (IR) is 2.0 µA at VR = 1.0 V and Tj = 25 °C, as specified in Table 8 of the datasheet. This value remains stable across −55 °C to +125 °C, enabling predictable low-power behavior in wide-temperature applications.
Can BZX8850-C2V4YL be used in forward conduction mode?
Yes - it functions as a standard silicon diode in forward bias, with a maximum forward voltage of 0.9 V at IF = 10 mA. Its 200 mA absolute maximum forward current rating supports transient clamping and dual-mode protection schemes without derating.
Is the SOD882 package compatible with standard reflow profiles?
Yes - Nexperia specifies compatibility with IPC/JEDEC J-STD-020D reflow profiles. The recommended solder land pattern (Fig. 10) uses 0.3 mm × 0.9 mm pads with 0.4 mm solder mask openings, ensuring reliable wetting and void-free joints on FR4 PCBs.
How does the ±2 % tolerance affect regulation accuracy in real-world circuits?
At 2.4 V nominal, ±2 % translates to ±48 mV absolute deviation. Combined with <0.5 mV/K temperature coefficient and <200 mΩ dynamic resistance, this ensures <±0.8 % total regulation error across −40 °C to +125 °C in properly decoupled circuits - sufficient for 10-bit ADC references and reset supervisors.
