Nexperia USA Inc. BZX884-C8V2,315

Overview

BZX884-C8V2,315 from Nexperia is a ±5 % tolerance Zener diode in SOD882 (DFN1006-2) package, providing 8.2 V nominal regulation at 5 mA with 20 Ω typical differential resistance and 4.3 mV/K temperature coefficient. It delivers 250 mW total power dissipation and supports ESD protection and voltage reference functions in space-constrained automotive and industrial PCBs.

For engineers reviewing the BZX884-C8V2,315 datasheet, BZX884-C8V2,315 pinout, BZX884-C8V2,315 application, or BZX884-C8V2,315 equivalent, this page provides verified Zener voltage, reverse leakage (700 nA at 5 V), forward voltage (≤0.9 V @ 10 mA), thermal resistance (500 K/W), and AEC-Q101 qualification status - all critical for low-power biasing and transient suppression design.

Technical Context

This Zener diode operates in reverse breakdown to maintain stable 8.2 V output across load and line variations, with tight ±5 % tolerance ensuring predictable clamping thresholds in precision reference circuits. Its ultra-small DFN1006-2 footprint enables high-density placement near IC power pins for local regulation and ESD immunity.

Designed for surface-mount reflow assembly only, it features cathode-marked top-side identification and meets AEC-Q101 stress testing for automotive under-hood environments. The 700 nA reverse leakage at VR = 5 V and 20 Ω dynamic impedance at IZ = 5 mA support low-current bias networks without excessive quiescent loss.

FAQ

What is the maximum reverse voltage the BZX884-C8V2,315 can withstand before breakdown?

The BZX884-C8V2,315 has a nominal Zener voltage of 8.2 V with a guaranteed range of 8.04 V to 8.36 V at 5 mA test current. Breakdown begins within this band; it is not rated for sustained operation above 8.36 V in regulation mode. Absolute maximum reverse voltage is not specified - operation beyond V_Z max risks thermal runaway if power dissipation exceeds 250 mW.

Is the SOD882 package compatible with standard reflow soldering profiles?

Yes - the SOD882 package is qualified for lead-free reflow soldering only, with peak temperatures up to 260 °C per JEDEC J-STD-020. The recommended profile includes ramp rate ≤3 °C/s, preheat 150–200 °C for 60–120 s, soak 200–220 °C for 60–120 s, and time above liquidus (217 °C) of 40–80 s. Wave soldering is not supported.

How does the +4.3 mV/K temperature coefficient affect circuit performance?

The +4.3 mV/K coefficient means the Zener voltage increases by approximately 4.3 mV per degree Celsius rise in junction temperature. At 85 °C ambient (assuming 25 °C rise), V_Z rises ~107 mV - from 8.2 V to ~8.31 V. This must be accounted for in precision references; compensation techniques include pairing with negative-TC components or using temperature-stable op-amp feedback.

Can BZX884-C8V2,315 replace older Zeners like BZX79-C8V2 in existing designs?

No direct drop-in replacement - BZX884-C8V2,315 uses SOD882 (1.0 × 0.6 mm), while BZX79-C8V2 uses DO-35 (4.5 × 2.5 mm). Layout redesign is required. Electrically, both offer ±5 % tolerance and similar V_Z, but BZX884 has lower r_diff (20 Ω vs. ~35 Ω) and higher thermal resistance (500 K/W vs. ~400 K/W), affecting power handling in confined spaces.
