Nexperia USA Inc. BZX884S-C24-QYL

Overview

BZX884S-C24-QYL from Nexperia is a precision Zener voltage regulator diode in the BZX884S-Q series, designed for stable voltage reference and overvoltage protection in compact automotive and industrial circuits. It delivers a nominal 24 V Zener voltage with ±5 % tolerance, 60 Ω typical differential resistance at 5 mA, and operates up to 150 °C junction temperature in the ultra-small DFN1006BD-2 (SOD882BD) package.

For engineers reviewing the BZX884S-C24-QYL datasheet, BZX884S-C24-QYL pinout, BZX884S-C24-QYL application, or BZX884S-C24-QYL equivalent, key selection considerations include its AEC-Q101 qualification, side-wettable flanks for automated optical inspection, 365 mW power dissipation on FR4, and low 0.05 μA reverse current at 19.2 V.

Technical Context

This Zener diode operates in reverse breakdown mode to maintain a stable 24 V reference across load variations and temperature shifts. Its −2.0 mV/K to +22.0 mV/K temperature coefficient (typical at I_Z = 5 mA) enables predictable regulation behavior in ambient ranges from −55 °C to +150 °C.

The device features low 55 pF capacitance at 1 MHz and 0 V reverse bias, supporting high-frequency noise suppression in power rail conditioning. Its 60 Ω differential resistance ensures tight regulation under dynamic current loads up to 200 mA forward/200 mA peak reverse surge.

FAQ

What is the maximum reverse voltage this Zener can clamp without damage?

The absolute maximum reverse voltage is not specified independently; instead, the device is rated for 200 mA peak reverse current and 365 mW total power dissipation. At 24 V nominal Zener voltage, sustained clamping above ~25.6 V (max V_Z) risks exceeding power limits unless current is strictly limited by series resistance - design must ensure I_Z stays within 5 mA to 200 mA per datasheet limiting values.

Does the side-wettable flank feature require special stencil or reflow profile?

No special stencil is needed - standard DFN1006BD-2 footprint (1.3 mm × 0.8 mm solder lands, 0.4 mm paste thickness) per Figure 11 applies. Reflow must follow JEDEC J-STD-020 profile for MSAL3 moisture sensitivity level; peak temperature ≤ 260 °C ensures flank wettability without voiding or delamination.

How does temperature affect regulation accuracy at 24 V output?

At I_Z = 5 mA, the temperature coefficient ranges from −2.0 mV/K to +22.0 mV/K depending on exact V_Z point within the 22.8 V–25.6 V band. For the center value (24.2 V), typical SZ is +18.4 mV/K - meaning output rises ~1.1 V over a 60 °C rise (e.g., 25 °C to 85 °C), which must be compensated in precision references.

Can this Zener replace a 1N4749A in an existing design?

Yes, electrically - both regulate at 24 V with ±5 % tolerance - but mechanical replacement requires footprint adaptation: BZX884S-C24-QYL uses DFN1006BD-2 (1.0 mm × 0.6 mm), while 1N4749A uses DO-41 (5.2 mm × 2.7 mm). No circuit redesign is needed, but PCB layout revision and reflow profile validation are mandatory due to package size and thermal mass differences.
