Nexperia USA Inc. BZX884-B3V0,315

Overview

BZX884-B3V0,315 from Nexperia is a ±2 % tolerance Zener diode in SOD882 (DFN1006-2) package, rated for 3.0 V nominal regulation at 5 mA, with 250 mW total power dissipation and 10 µA reverse current at VR = 1 V - used for precision voltage reference and ESD clamping in space-constrained consumer and automotive sensor circuits.

For engineers reviewing the BZX884-B3V0,315 datasheet, BZX884-B3V0,315 pinout, BZX884-B3V0,315 application, or BZX884-B3V0,315 equivalent, key selection criteria include Zener voltage tolerance (±2 %), low differential resistance (325–500 Ω at 1 mA), temperature coefficient (−1.6 mV/K), cathode-marked ultra-small footprint (1.0 × 0.6 mm), and AEC-Q101 qualification for automotive-grade reliability.

Technical Context

This Zener diode operates in reverse breakdown to maintain stable voltage under varying load and temperature conditions. Its −1.6 mV/K temperature coefficient ensures predictable drift across −55 °C to +150 °C ambient range, and its 325–500 Ω dynamic impedance at 1 mA supports tight regulation in low-current bias networks.

The device features a leadless DFN1006-2 package with cathode marked by a bar on the top surface, enabling high-density PCB layouts. It meets AEC-Q101 stress testing requirements including temperature cycling, humidity bias, and ESD (HBM > 8 kV), confirming suitability for automotive infotainment and body electronics.

FAQ

What is the maximum reverse current for BZX884-B3V0,315 at 1 V reverse bias?

The maximum reverse current is 10 µA at VR = 1 V and Tj = 25 °C, as specified in Table 7 of the datasheet. This low leakage ensures minimal power loss in battery-backed or always-on circuits, and remains stable across the full operating temperature range due to the device's controlled junction characteristics.

Is BZX884-B3V0,315 suitable for ESD protection in USB interfaces?

Yes - it delivers ultra-high-speed ESD clamping with a non-repetitive peak reverse current rating of 6 A (tp = 100 µs) and low dynamic impedance (325–500 Ω). Its 3.0 V Zener voltage aligns with 3.3 V logic rails, and the SOD882 package enables placement directly at USB-C connector pads for effective transient suppression before signal integrity degradation.

How does the −1.6 mV/K temperature coefficient affect circuit performance?

This coefficient means the Zener voltage decreases by 1.6 mV per Kelvin rise in junction temperature. Over a 100 K range (e.g., −40 °C to +60 °C), total drift is ~160 mV - well within the ±2 % tolerance band (±60 mV). Designers use this predictable drift for passive compensation or select it where monotonic behavior simplifies calibration routines in analog sensor interfaces.

Can BZX884-B3V0,315 be soldered using standard reflow profiles?

Yes - Nexperia specifies reflow soldering as the only recommended method, with compatible profiles aligned to JEDEC J-STD-020. The SOD882 package withstands peak temperatures up to 260 °C for ≤ 30 seconds. Footprint dimensions (0.7 × 0.3 mm solder pads, 0.5 mm pitch) are defined in Figure 12, and thermal resistance (R_th(j-a) = 500 K/W) assumes standard FR4 with 60 µm copper traces.
