Product details
Overview
BZX884S-B4V7-QYL from Nexperia is a 4.7 V ±2 % tolerance Zener diode in an ultra-small DFN1006BD-2 (SOD882BD) leadless SMD package with side-wettable flanks, designed for precision voltage regulation and reference functions in space-constrained automotive and industrial circuits. It delivers 4.7 V nominal breakdown at 5 mA, exhibits 425 Ω typical differential resistance, supports 200 mA maximum forward current, and operates across −55 °C to +150 °C ambient.
For engineers reviewing the BZX884S-B4V7-QYL datasheet, BZX884S-B4V7-QYL pinout, BZX884S-B4V7-QYL application, or BZX884S-B4V7-QYL equivalent, this part is selected for low-profile voltage clamping, overvoltage protection, and stable biasing where AEC-Q101 qualification, tight tolerance, and thermal robustness are required in high-reliability PCB layouts.
Technical Context
This Zener diode operates in reverse-biased breakdown mode to maintain a stable 4.7 V reference under regulated current conditions (IZ = 5 mA). Its temperature coefficient of −3.5 mV/K to +0.2 mV/K ensures predictable drift behavior across operating temperature, and its 170 pF capacitance at 1 MHz / 0 V enables use in moderate-frequency stabilization without excessive signal coupling.
The device uses silicon planar Zener technology with cathode-anode polarity defined by a marking bar on the package top surface. It is qualified per AEC-Q101 for automotive applications and rated for 365 mW total power dissipation on standard FR4 PCBs with 70 μm copper.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 4.61 V to 4.79 V at IZ = 5 mA - defines precise clamping threshold for protection and reference circuits |
| Tolerance | ±2 % - enables tighter system-level voltage margin control vs. ±5 % variants |
| Differential Resistance (rdif) | 425 Ω typical at IZ = 5 mA - determines regulation stiffness and output impedance under load variation |
| Forward Voltage (VF) | ≤0.9 V at IF = 10 mA - ensures low-loss conduction during forward-bias fault conditions |
| Power Dissipation (Ptot) | 365 mW on FR4 PCB - sets maximum continuous steady-state power handling in standard layout |
| Junction Temperature (Tj) | −55 °C to +150 °C - supports operation in under-hood automotive and industrial environments |
| Reverse Current (IR) | ≤3 μA at VR = 3.76 V - guarantees low leakage before breakdown onset |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX884S-C4V7-Q | ±5 % tolerance (4.4 V–5.0 V), higher IR (≤3 μA), same package and thermal specs | Suitable for non-critical biasing where cost sensitivity outweighs precision | Select when ±2 % tolerance is not required and BOM cost reduction is prioritized |

FAQ
What is the maximum reverse working voltage before breakdown for BZX884S-B4V7-QYL?
The guaranteed breakdown occurs between 4.61 V and 4.79 V at 5 mA test current. Below 3.76 V, reverse current remains ≤3 μA - confirming stable non-conducting behavior up to that point. This makes it suitable for clamping applications where strict pre-breakdown isolation is required.
Can BZX884S-B4V7-QYL be used in place of a 5.1 V Zener diode?
No - its nominal Zener voltage is 4.7 V with ±2 % tolerance (4.61–4.79 V), which does not overlap the 5.1 V ±2 % range (4.998–5.202 V). Substituting it for a 5.1 V part would result in premature clamping and potential system malfunction under normal 5 V rail operation.
Is the DFN1006BD-2 package compatible with standard reflow profiles?
Yes - Nexperia specifies reflow soldering as the only recommended method, and the package is qualified for JEDEC J-STD-020 moisture sensitivity level 1. The side-wettable flanks support automated optical inspection, and the footprint matches IPC-7351B density Level A guidelines for reliable assembly.
How does temperature affect the Zener voltage stability of this device?
At 5 mA, its temperature coefficient ranges from −3.5 mV/K to +0.2 mV/K, meaning VZ may decrease by up to 3.5 mV per Kelvin rise or increase slightly near 4.7 V. This results in ≤±25 mV drift over −40 °C to +125 °C, supporting stable performance in automotive under-hood environments.
