Nexperia USA Inc. BZX884-C6V8,315

Overview

BZX884-C6V8,315 from Nexperia is a ±5 % tolerance Zener diode in SOD882 (DFN1006-2) package, rated for 6.66 V to 6.94 V nominal Zener voltage at 5 mA, with 30 Ω typical differential resistance and 3.0 mV/K temperature coefficient. It delivers 250 mW total power dissipation and supports ESD protection and voltage regulation in space-constrained high-frequency circuits.

For engineers reviewing the BZX884-C6V8,315 datasheet, BZX884-C6V8,315 pinout, BZX884-C6V8,315 application, or BZX884-C6V8,315 equivalent, this part serves as a compact, AEC-Q101 qualified Zener for precision clamping, low-leakage biasing, and transient suppression where thermal resistance (500 K/W) and reverse current (2 µA at 4 V) are critical selection factors.

Technical Context

This Zener diode operates in reverse breakdown mode with tightly controlled voltage regulation across its ±5 % tolerance band. Its 30 Ω typical differential resistance at 5 mA ensures stable output under varying load currents, while the +3.0 mV/K temperature coefficient enables predictable drift compensation in ambient ranges from −55 °C to +150 °C.

The device uses a planar silicon junction structure optimized for low capacitance (215 pF at 1 MHz, VR = 0 V) and fast response in ESD events. Its SOD882 footprint supports reflow-only assembly on FR4 PCBs with standard 0.6 mm × 1.0 mm land patterns and 60 µm copper traces.

FAQ

What is the maximum reverse voltage that BZX884-C6V8,315 can safely clamp?

The BZX884-C6V8,315 is rated for non-repetitive peak reverse voltage events up to 6 A for 100 µs pulses at 25 °C ambient, corresponding to a peak power of approximately 40 W. Its absolute maximum reverse voltage is not specified independently, but operation above 6.94 V initiates controlled Zener conduction; sustained reverse bias beyond 250 mW dissipation risks thermal runaway.

How does the ±5 % tolerance affect circuit design margins?

The ±5 % tolerance means the actual Zener voltage falls between 6.66 V and 6.94 V at 5 mA, requiring design margins to accommodate this 280 mV window. For example, in a 7 V rail clamp, minimum clamping occurs at 6.66 V, leaving 340 mV headroom-sufficient to prevent downstream IC damage while avoiding premature triggering during normal transients.

Can BZX884-C6V8,315 be used in forward-bias applications?

Yes-the device exhibits a maximum forward voltage of 0.9 V at 10 mA, making it usable as a low-drop rectifier or level-shifter in low-current signal paths. However, its primary design intent is reverse-bias Zener operation; forward conduction should be limited to ≤200 mA per absolute maximum ratings to avoid bond-wire fusing.

Is the SOD882 package compatible with standard reflow soldering profiles?

Yes-Nexperia specifies reflow soldering as the only recommended process for SOD882. The package supports JEDEC J-STD-020-compliant profiles with peak temperatures up to 260 °C, provided the footprint matches the 0.6 mm × 1.0 mm pad layout and solder paste volume is controlled to prevent bridging between the two exposed terminals.
