Product details
Overview
BZX884S-B5V6-QYL from Nexperia is a ±2 % tolerance Zener diode in a DFN1006BD-2 (SOD882BD) leadless SMD package, providing precise 5.6 V voltage regulation at 5 mA test current with 15 Ω typical differential resistance and −2.0 to +2.5 mV/K temperature coefficient. It delivers 365 mW power dissipation on FR4 PCB and is AEC-Q101 qualified for automotive power rail stabilization.
For engineers reviewing the BZX884S-B5V6-QYL datasheet, BZX884S-B5V6-QYL pinout, BZX884S-B5V6-QYL application, or BZX884S-B5V6-QYL equivalent, this page provides verified Zener voltage, thermal resistance (340 K/W), cathode/anode terminal mapping, side-wettable flank soldering compatibility, and automotive-grade reliability data - all confirmed from Nexperia's official Rev. 2 product data sheet dated 5 May 2021.
Technical Context
This Zener diode operates in reverse breakdown mode with a nominal 5.6 V working voltage (5.49–5.71 V range) and exhibits low dynamic impedance (80 Ω max at IZ = 1 mA, 400 Ω max at IZ = 5 mA), enabling stable reference performance under varying load conditions. Its temperature coefficient of −2.0 to +2.5 mV/K ensures predictable drift across −55 °C to +150 °C ambient operation.
Designed for surface-mount use on standard FR4 PCBs with 70 μm tin-plated copper, it supports reflow-only soldering and leverages side-wettable flanks for automated optical inspection (AOI) of solder joints. The device meets AEC-Q101 stress testing requirements, confirming suitability for under-hood automotive electronics where thermal cycling and vibration resilience are critical.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C5V6 | ±5 % tolerance, SOT23 package (3.0 mm × 1.4 mm), higher Rth(j-a) ≈ 450 K/W | Larger footprint and looser voltage accuracy limit use in high-density automotive PCBs | Select when cost sensitivity outweighs space and precision requirements |
| MMSZ5232B | ±5 % tolerance, SOD-123 package (2.7 mm × 1.4 mm), 500 mW Ptot rating | Higher power handling but no AEC-Q101 qualification or side-wettable flanks | Prefer for industrial non-automotive applications requiring >365 mW dissipation |
Compared with BZX884S-B5V6-QYL, BZX84-C5V6 trades precision and miniaturization for cost, while MMSZ5232B offers higher power margin at the expense of automotive qualification and AOI-compatible packaging - making the BZX884S-B5V6-QYL optimal for space-constrained, thermally demanding, and safety-critical vehicle systems.

FAQ
What is the maximum reverse current at 4.5 V for BZX884S-B5V6-QYL?
The maximum reverse current is 1 μA at VR = 4.5 V and Tj = 25 °C, as specified in Table 8 of the Nexperia datasheet. This low leakage ensures minimal quiescent power draw in always-on sensor bias networks and supports long-term battery-backed operation in telematics modules.
Does BZX884S-B5V6-QYL support reflow soldering only, or can it be hand-soldered?
Reflow soldering is the only recommended method per Section 12 of the datasheet. Hand-soldering is not advised due to the DFN1006BD-2 package's small pitch (0.65 mm), low profile (0.47 mm height), and requirement for uniform heating to achieve reliable side-wettable flank solder joints.
How does the temperature coefficient affect regulation accuracy over automotive temperature ranges?
With a specified SZ of −2.0 to +2.5 mV/K, the Zener voltage drift is bounded: at 125 °C ambient (assuming ~130 °C junction), worst-case shift is ±0.28 V from nominal 5.6 V. This remains within functional limits for 5 V system rails protected by downstream LDOs or supervisors.
Is the marking code '2K' visible on the top surface of BZX884S-B5V6-QYL?
Yes - per Table 4 and Figure 10, the marking '2K' is laser-etched on the top surface of the DFN1006BD-2 package, with the cathode indicated by a bar adjacent to pin 1. This allows visual polarity verification during manual assembly and automated optical inspection.
