Product details
Overview
BZX884S-B5V1-QYL from Nexperia is a ±2 % tolerance Zener diode in SOD882BD (DFN1006BD-2) package, designed for precision voltage regulation at 5.1 V nominal breakdown voltage with 400 Ω typical differential resistance at IZ = 5 mA and −2.7 mV/K temperature coefficient. It delivers stable reference voltage in automotive power supply monitoring circuits under ambient temperatures from −55 °C to +150 °C.
For engineers reviewing the BZX884S-B5V1-QYL datasheet, BZX884S-B5V1-QYL pinout, BZX884S-B5V1-QYL application, or BZX884S-B5V1-QYL equivalent, this page provides verified Zener voltage, thermal resistance, side-wettable flank solderability, AEC-Q101 qualification status, and automotive-grade reliability data required for board-level validation and long-life design assurance.
Technical Context
This Zener diode operates in reverse-biased breakdown mode with a nominal VZ of 5.1 V at IZ = 5 mA, exhibiting low dynamic impedance (400 Ω typ.) and tight ±2 % tolerance. Its temperature coefficient of −2.7 mV/K ensures predictable drift over −55 °C to +150 °C ambient range.
The device uses a planar epitaxial process and is qualified to AEC-Q101, enabling use in automotive body control modules and engine management subsystems where stable voltage clamping and ESD-robust reference generation are required under thermal stress and vibration.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 5.00 V to 5.20 V at IZ = 5 mA - defines precise clamping threshold for 5 V rail protection |
| Tolerance | ±2 % - enables high-accuracy voltage reference without post-production trimming |
| Differential Resistance rdif | 400 Ω typical at IZ = 5 mA - ensures minimal output voltage variation under load current shifts |
| Temperature Coefficient SZ | −2.7 mV/K - quantifies predictable negative drift for thermal compensation design |
| Power Dissipation Ptot | 365 mW on FR4 PCB with 70 μm copper - sets maximum continuous DC/low-frequency power handling |
| Junction Temperature Tj | 150 °C max - supports operation in under-hood automotive environments |
| Forward Voltage VF | 0.9 V max at IF = 10 mA - defines forward conduction loss during transient polarity reversal |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C5V1,115 | ±5 % tolerance, SOT23 package, 500 mW Ptot, higher rdif (600 Ω typ.) | Larger footprint; unsuitable for SWF AOI or ultra-dense layouts | Select when cost sensitivity outweighs precision and space constraints |
| MMSZ5231B-TP | ±5 % tolerance, SOD-123 package, 500 mW Ptot, no AEC-Q101 qualification | Not automotive-qualified; lacks side-wettable flank geometry | Acceptable for industrial/commercial designs where AEC-Q101 is not mandated |
Compared with BZX884S-B5V1-QYL, BZX84-C5V1 offers higher power but looser tolerance and larger package, while MMSZ5231B-TP lacks automotive qualification and SWF capability-making the QYL variant uniquely suited for space-limited, safety-critical automotive voltage supervision.

FAQ
What is the maximum reverse current at 4.5 V for BZX884S-B5V1-QYL?
At VR = 4.5 V and Tj = 25 °C, the reverse current is ≤2 μA per datasheet Table 8. This ultralow leakage ensures minimal standby power draw in battery-supplied systems and maintains accuracy in high-impedance reference circuits without loading error.
Is BZX884S-B5V1-QYL compatible with lead-free reflow profiles?
Yes - the SOD882BD package is qualified for standard IPC/JEDEC J-STD-020D reflow profiles, including peak temperatures up to 260 °C. The side-wettable flanks ensure reliable solder joint formation and AOI detectability under lead-free conditions.
How does the −2.7 mV/K temperature coefficient affect regulation accuracy at 125 °C?
From 25 °C to 125 °C (ΔT = 100 K), VZ shifts by −0.27 V, resulting in a regulated voltage of ~4.83 V. This predictable linear drift allows system designers to compensate in firmware or select complementary components for tighter overall tolerance.
Can BZX884S-B5V1-QYL replace BZX84-B5V1 in existing SOT23 designs?
No - BZX884S-B5V1-QYL uses DFN1006BD-2 (SOD882BD) packaging, not SOT23. Direct replacement requires PCB layout revision due to different footprint, pitch (0.65 mm vs. 1.9 mm), and soldering methodology (SWF reflow vs. gull-wing reflow).
