Product details
Overview
BZX884S-B2V4-Q from Nexperia is a 2.4 V ±2 % tolerance Zener diode in a leadless DFN1006BD-2 (SOD882BD) package, designed for precision voltage regulation and reference functions in space-constrained automotive and industrial circuits. It delivers 365 mW power dissipation at 25 °C, exhibits 275 Ω typical differential resistance at 5 mA, and features side-wettable flanks for reliable automated optical inspection (AOI) during reflow soldering.
For engineers reviewing the BZX884S-B2V4-Q datasheet, BZX884S-B2V4-Q pinout, BZX884S-B2V4-Q application, or BZX884S-B2V4-Q equivalent, this page provides verified Zener voltage, thermal resistance, reverse current limits, cathode/anode terminal mapping, and AEC-Q101-qualified automotive suitability - all critical for low-voltage biasing, overvoltage clamping, and reference stability validation.
Technical Context
This Zener diode operates in reverse breakdown mode with a nominal Zener voltage of 2.4 V at 5 mA test current, maintaining tight ±2 % tolerance across temperature. Its differential resistance of 275 Ω (typ.) ensures stable regulation under varying load currents, while the negative temperature coefficient of −3.5 mV/K supports predictable drift behavior in ambient ranges from −55 °C to +150 °C.
The device uses a planar epitaxial silicon process and is qualified to AEC-Q101, confirming robustness against thermal cycling, humidity, and mechanical stress in automotive ECUs and ADAS sensor modules. Its ultra-small 1.0 mm × 0.6 mm footprint with side-wettable flanks enables high-density PCB layouts compatible with IPC-7351B reflow profiles.

FAQ
What is the maximum reverse current specification for BZX884S-B2V4-Q at 1.0 V?
The maximum reverse current (IR) is 50 μA at VR = 1.0 V and Tj = 25 °C, per Table 8 of the datasheet. This low leakage supports energy-efficient operation in always-on monitoring circuits and extends battery life in portable devices.
Does BZX884S-B2V4-Q require a series current-limiting resistor in shunt regulator configurations?
Yes - a series resistor is mandatory to limit Zener current within the 365 mW power rating and prevent thermal runaway. For example, at 5 V input and 2.4 V output, a minimum 520 Ω resistor limits IZ to 5 mA, aligning with the specified test condition and ensuring stable regulation.
Is the DFN1006BD-2 package compatible with standard reflow soldering profiles?
Yes - Nexperia specifies reflow soldering as the only recommended method. The SOD882BD footprint (1.4 mm pad length, 0.7 mm pad width, 0.65 mm pitch) complies with IPC-7351B and supports peak temperatures up to 260 °C, provided solder paste volume and thermal mass are optimized per JEDEC J-STD-020.
How does the temperature coefficient affect regulation accuracy over automotive temperature ranges?
With a typical SZ of −3.5 mV/K, the Zener voltage drifts −84 mV from 25 °C to 125 °C ambient (ΔT = 100 K). Combined with ±2 % initial tolerance (±48 mV), total worst-case deviation is ±132 mV - well within 2.4 V ±5 % system-level requirements for most sensor biasing applications.
