Nexperia USA Inc. BZX884-C5V6,315

Overview

BZX884-C5V6,315 from Nexperia is a ±5 % tolerance Zener diode in SOD882 (DFN1006-2) package, designed for precision voltage regulation and ESD protection at 5.6 V nominal Zener voltage with 1 µA reverse current at VR = 2 V, 80 Ω typical differential resistance at IZ = 5 mA, and 1.0 mV/K temperature coefficient - used in low-power rail clamping and signal-level voltage reference circuits.

For engineers reviewing the BZX884-C5V6,315 datasheet, BZX884-C5V6,315 pinout, BZX884-C5V6,315 application, or BZX884-C5V6,315 equivalent, key selection criteria include Zener voltage tolerance, dynamic impedance at 5 mA, thermal resistance (500 K/W), cathode-marking orientation, and AEC-Q101 qualification for automotive-grade reliability.

Technical Context

This Zener diode operates in reverse breakdown to maintain stable 5.6 V across its terminals under regulated current conditions, with specified test current of 5 mA and maximum power dissipation of 250 mW at Tamb ≤ 25 °C on FR4 PCB. Its ultra-small DFN1006-2 footprint enables high-density placement in space-constrained designs.

It exhibits a positive temperature coefficient of +1.0 mV/K at IZ = 5 mA, indicating voltage increases with junction temperature - critical for thermal drift compensation in reference circuits. Reverse leakage remains ≤1 µA at VR = 2 V, supporting low-quiescent-current bias networks.

FAQ

What is the maximum continuous reverse current the BZX884-C5V6,315 can handle without degradation?

The device is rated for a maximum non-repetitive peak reverse current (IZSM) of 6 A at tp = 100 µs, but continuous reverse current must remain below the DC Zener test current of 5 mA to avoid thermal runaway. At 25 °C ambient and standard FR4 mounting, sustained operation above 1 mA requires derating per Rth(j-a) = 500 K/W to prevent exceeding Tj = 150 °C.

How does the +1.0 mV/K temperature coefficient affect long-term voltage reference stability?

A +1.0 mV/K coefficient means the Zener voltage increases by ~5.6 mV over a 5.6 K (≈5.6 °C) ambient rise - translating to ~0.1 % drift per 10 °C. For applications requiring <0.5 % total drift over −40 to +125 °C, system-level compensation or tighter-tolerance variants (e.g., BZX884-B5V6) should be considered.

Can the BZX884-C5V6,315 be used in bidirectional ESD protection configurations?

Yes - its symmetric structure allows use as a bidirectional clamp: anode-to-ground/cathode-to-line for positive transients, and forward conduction (VF ≤ 0.9 V) for negative transients. This dual-mode behavior meets IEC 61000-4-2 requirements without external series resistors in low-capacitance signal paths.

Is the SOD882 package compatible with standard reflow soldering profiles?

Yes - Nexperia specifies reflow soldering as the only recommended method, with footprint dimensions published in Figure 12 (sod882_fr). The package supports JEDEC J-STD-020-compliant profiles, including peak temperatures up to 260 °C, and requires no special stencil design beyond the 0.3 mm solder paste openings shown in the datasheet.
