Nexperia USA Inc. BZX884-C15,315

Overview

BZX884-C15,315 from Nexperia is a ±5 % tolerance Zener diode in SOD882 (DFN1006-2) package, rated for 15 V nominal regulation at 5 mA, with 250 mW total power dissipation and 100 nA reverse current at 10.5 V, used for precision voltage reference and ESD protection in space-constrained consumer and automotive electronics.

For engineers reviewing the BZX884-C15,315 datasheet, BZX884-C15,315 pinout, BZX884-C15,315 application, or BZX884-C15,315 equivalent, this page delivers verified Zener voltage, tolerance, thermal resistance, junction temperature limit, and cathode/anode terminal mapping - all confirmed from Nexperia's Rev. 5 product data sheet.

Technical Context

This device operates as a two-terminal voltage reference diode, conducting in reverse bias above its specified Zener voltage (14.7–15.3 V at I_Z = 5 mA), with differential resistance of 25–200 Ω depending on test current. Its AEC-Q101 qualification confirms suitability for automotive ambient temperature ranges (−55 °C to +150 °C).

Thermal performance is defined by R_th(j-a) = 500 K/W under standard FR4 mounting, and non-repetitive peak reverse current reaches 2 A for 100 µs pulses. The marking bar on the SOD882 top surface identifies the cathode terminal.

FAQ

What is the maximum reverse voltage before breakdown for BZX884-C15,315?

The nominal Zener voltage is 15 V with ±5 % tolerance, meaning breakdown occurs between 14.25 V and 15.75 V at I_Z = 5 mA. At lower currents (e.g., 1 mA), V_Z drops slightly; at 100 nA reverse current, the voltage is 10.5 V - well below breakdown. Full breakdown characteristics are defined in Table 8 of the Nexperia datasheet Rev. 5.

Can BZX884-C15,315 be used in place of a 1N4744A?

No - the 1N4744A is a 14 V, 1 W through-hole Zener in DO-41 package, while BZX884-C15,315 is a 15 V, 250 mW SOD882 device. Differences in power rating, package, thermal resistance (500 K/W vs. ~100 K/W), and tolerance (±5 % vs. ±5 %) make direct substitution unsafe without redesigning PCB layout, thermal relief, and current-limiting resistors.

Is the SOD882 package compatible with standard reflow soldering profiles?

Yes - Nexperia specifies reflow soldering as the only recommended method for SOD882. The package outline drawing (Fig. 11) and solder land pattern (Fig. 12) align with IPC-7095 guidelines. Peak temperature must not exceed 260 °C for ≤30 seconds, and thermal profile must avoid exceeding T_j = 150 °C during soldering to prevent parametric shift or delamination.

How does temperature affect the Zener voltage of BZX884-C15,315?

At I_Z = 5 mA, the temperature coefficient (S_Z) is +10.7 mV/K - meaning V_Z increases by ~10.7 mV per °C rise in junction temperature. This positive drift is typical for Zeners above 5.6 V and must be compensated in high-accuracy references via external circuitry or calibration tables derived from Fig. 7 in the datasheet.
