Product details
Overview
BZX884S-C4V7-QYL from Nexperia is a ±5 % tolerance Zener diode optimized for precision voltage regulation and overvoltage protection in space-constrained automotive and industrial circuits, with a nominal Zener voltage of 4.7 V, 365 mW power dissipation, and DFN1006BD-2 (SOD882BD) leadless package with side-wettable flanks.
For engineers reviewing the BZX884S-C4V7-QYL datasheet, BZX884S-C4V7-QYL pinout, BZX884S-C4V7-QYL application, or BZX884S-C4V7-QYL equivalent, this page delivers verified Zener parameters including VZ = 4.4–5.0 V at IZ = 5 mA, differential resistance ≤425 Ω, temperature coefficient −3.5 to +0.2 mV/K, reverse current ≤3 μA at VR = 3.5 V, and thermal resistance Rth(j-a) = 340 K/W on FR4.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain stable reference voltage under varying load and temperature conditions. Its low-profile SOD882BD package enables high-density PCB layouts while supporting automated optical inspection (AOI) via side-wettable flanks.
Designed per AEC-Q101, it sustains operation from −55 °C to +150 °C ambient and supports junction temperatures up to 150 °C. The device exhibits a typical Zener knee at 4.7 V with 5 mA test current and maintains <3 μA leakage at 3.5 V reverse bias.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 4.4 V to 5.0 V at IZ = 5 mA - defines regulated output range for low-voltage rail clamping |
| Differential Resistance rdif | ≤425 Ω at IZ = 5 mA - determines voltage regulation stiffness against load current variation |
| Temperature Coefficient SZ | −3.5 mV/K to +0.2 mV/K - quantifies VZ drift across operating temperature range |
| Reverse Current IR | ≤3 μA at VR = 3.5 V - ensures minimal quiescent power loss in standby regulation |
| Total Power Dissipation Ptot | 365 mW on FR4 PCB (70 μm Cu) - sets maximum continuous power handling in standard layout |
| Junction Temperature Tj | 150 °C absolute maximum - defines thermal derating limit for reliability-critical designs |
| Package | DFN1006BD-2 (SOD882BD), 1.0 mm × 0.6 mm × 0.47 mm - enables 0201-class board area with AOI-compatible terminations |
Pinout & Package
DFN1006BD-2 (SOD882BD) is a 2-terminal leadless plastic package with side-wettable flanks, 0.65 mm pitch, and cathode indicated by a marking bar on the top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to regulated output node; polarity marker aligns with PCB silkscreen bar |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX884S-B4V7-Q | ±2 % VZ tolerance (4.61–4.79 V) vs. ±5 % (4.4–5.0 V); identical package and thermal specs | Required where tighter regulation stability is needed for metrology-grade references | Select when VZ accuracy dominates over cost; same footprint and reflow profile |
| MMSZ4705T1G | ±5 % VZ (4.47–4.93 V), SOD-123 package (2.7 mm × 1.6 mm), higher Ptot = 500 mW | Suitable for higher-power regulation where board space permits larger footprint | Choose when thermal margin >365 mW is required and 0201-class size is not mandatory |
Compared with BZX884S-C4V7-QYL, the BZX884S-B4V7-Q offers tighter voltage control at identical size and reliability, while MMSZ4705T1G trades miniaturization for higher power handling and legacy package compatibility.

FAQ
What is the maximum forward current rating for BZX884S-C4V7-QYL?
The absolute maximum forward current is 200 mA per IEC 60134 limiting values. However, the device is intended for reverse-bias Zener operation; forward conduction is only relevant during transient polarity reversal or ESD events, and sustained forward current above 10 mA risks thermal runaway due to low VF and limited Ptot.
Can BZX884S-C4V7-QYL be used in parallel for higher power dissipation?
No-Zener diodes exhibit negative temperature coefficients and mismatched VZ tolerances, causing current hogging when paralleled. Even with matched units, thermal coupling differences lead to uneven power sharing; use a single higher-rated Zener or active regulation instead.
Is the SOD882BD package compatible with standard 0201 pick-and-place equipment?
Yes-the DFN1006BD-2 outline matches 0201 land patterns in width and length (1.0 mm × 0.6 mm), and its side-wettable flanks are recognized by modern vision-guided placement systems for accurate centroid detection and coplanarity verification.
How does the ±5 % tolerance affect regulation accuracy in a 5 V rail?
At 4.7 V nominal, ±5 % yields a 4.4–5.0 V band, resulting in ±6.4 % deviation from a 5 V target. For tighter regulation, pair with an LDO or use the ±2 % BZX884S-B4V7-Q variant; this tolerance is appropriate for non-critical clamping where headroom exceeds 0.3 V.
