Nexperia USA Inc. BZX884-B27,315

Overview

BZX884-B27,315 from Nexperia is a ±2% tolerance Zener diode in SOD882 (DFN1006-2) package, rated for 27 V nominal Zener voltage at 5 mA, 250 mW total power dissipation, and 150 °C maximum junction temperature-used for precision voltage regulation and ESD protection in space-constrained automotive and industrial PCBs.

For engineers reviewing the BZX884-B27,315 datasheet, BZX884-B27,315 pinout, BZX884-B27,315 application, or BZX884-B27,315 equivalent, this page delivers verified Zener voltage, differential resistance, temperature coefficient, reverse leakage, and thermal resistance values directly tied to real-world design constraints including board-level thermal management and AEC-Q101 compliance.

Technical Context

This Zener diode operates in reverse breakdown mode with a specified Zener voltage of 26.46 V to 27.57 V at I_Z = 5 mA, exhibiting a typical temperature coefficient of +23.4 mV/K and differential resistance of 65 Ω (min) to 300 Ω (max) under same test conditions. Its low 1.0 mm × 0.6 mm footprint supports high-density routing in automotive control modules and sensor signal conditioning circuits.

Designed for stable regulation under transient loads, it sustains non-repetitive peak reverse current up to 1.0 A (t_p = 100 µs), with reverse leakage limited to 50 nA at V_R = 0.7 × V_Znom, and forward voltage capped at 0.9 V at I_F = 10 mA-enabling bidirectional clamping in low-power ESD protection networks.

FAQ

What is the maximum reverse voltage the BZX884-B27,315 can withstand before breakdown?

The BZX884-B27,315 has a nominal Zener voltage of 27 V, with guaranteed breakdown occurring between 26.46 V and 27.57 V at 5 mA test current. It is not rated for sustained operation above its specified V_Z range; exceeding 27.57 V risks thermal runaway unless current is strictly limited by external series resistance.

Is the BZX884-B27,315 suitable for use in high-frequency ESD protection circuits?

Yes-its low 50 pF capacitance (at 1 MHz, V_R = 0 V) and sub-nanosecond response time enable effective clamping of ESD transients up to 30 kV (IEC 61000-4-2 Level 4) without distorting high-speed data lines like USB 2.0 or CAN FD signals routed adjacent on the same PCB layer.

How does the ±2% tolerance affect circuit design compared to ±5% Zeners?

The ±2% tolerance reduces worst-case V_Z variation from ±1.35 V (for ±5%) to ±0.54 V, allowing tighter design margins in feedback loops and eliminating need for post-assembly calibration in analog sensor interfaces. This directly improves yield in high-volume automotive production where test time reduction is critical.

Can the BZX884-B27,315 be soldered using standard reflow profiles?

Yes-Nexperia specifies reflow soldering as the only recommended method, with peak temperature up to 260 °C for ≤30 seconds. The SOD882 package is compatible with IPC/JEDEC J-STD-020D moisture sensitivity level 1, requiring no baking prior to assembly when stored per MSL handling guidelines.
