Product details
Overview
BZX884S-C2V7-QYL from Nexperia is a ±5 % tolerance Zener diode in SOD882BD (DFN1006BD-2) package, rated for 2.7 V nominal breakdown voltage at 5 mA, 365 mW power dissipation, and qualified to AEC-Q101 for automotive voltage regulation. It operates across −55 °C to +150 °C ambient and features side-wettable flanks for automated optical inspection.
For engineers reviewing the BZX884S-C2V7-QYL datasheet, BZX884S-C2V7-QYL pinout, BZX884S-C2V7-QYL application, or BZX884S-C2V7-QYL equivalent, this page delivers verified Zener parameters, cathode/anode terminal mapping, automotive-grade thermal limits, and direct-fit alternatives with documented voltage tolerance and temperature coefficient differences.
Technical Context
This device functions as a precision shunt voltage regulator, maintaining stable reference voltage under reverse-biased operation with 2.50 V to 2.90 V working range at IZ = 5 mA. Its differential resistance of 300 Ω (typ.) and temperature coefficient of −3.5 mV/K (typ.) enable predictable drift behavior in low-power bias networks.
Designed for surface-mounted use on FR4 PCBs with single-sided 70 μm copper, it delivers 365 mW total power dissipation and supports forward conduction up to 200 mA, while junction temperature remains within 150 °C absolute maximum under defined mounting conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 2.7 V nominal at IZ = 5 mA; actual range 2.50 V–2.90 V defines usable regulation window in low-voltage reference circuits |
| Tolerance | ±5 % (C-series); sets worst-case output deviation for supply rail clamping or feedback node stabilization |
| Power Dissipation Ptot | 365 mW at Tamb = 25 °C on standard FR4; determines maximum continuous Zener current before thermal derating |
| Differential Resistance rdif | 300 Ω typical at IZ = 5 mA; quantifies dynamic impedance affecting regulation stiffness under load transients |
| Temperature Coefficient SZ | −3.5 mV/K typical; enables prediction of VZ drift over operating temperature range for stability-critical designs |
| Reverse Current IR | 20 μA max at VR = 1 V; defines leakage contribution to quiescent current in high-impedance bias networks |
| Forward Voltage VF | 0.9 V max at IF = 10 mA; constrains forward conduction loss when used in polarity protection or ESD paths |
Pinout & Package
Package: SOD882BD (DFN1006BD-2), ultra-small leadless plastic package measuring 1.0 mm × 0.6 mm × 0.47 mm with side-wettable flanks for solder joint inspection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Marked by bar on top surface; connects to regulated voltage node in shunt configuration |
| 2 | Anode (A) | Connects to ground or lower-potential reference; completes reverse-bias path for Zener operation |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive applications including engine control units and body electronics requiring reliability under thermal cycling and vibration |
| Side-wettable flanks | Enables automated optical inspection (AOI) of solder joints without X-ray, reducing post-reflow defect escape in high-volume SMT lines |
| Ultra-small DFN footprint | 1.0 mm × 0.6 mm area saves board space in space-constrained modules such as ADAS sensors and infotainment power supplies |
| Two tolerance options | ±2 % (B-series) and ±5 % (C-series) allow cost/performance trade-off selection for non-critical vs. precision regulation tasks |
| Wide voltage range coverage | 2.4 V to 75 V in E24 steps supports standardized design reuse across multiple voltage rails in multi-rail automotive ECUs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX884S-B2V7-Q | ±2 % tolerance (vs. ±5 %); tighter VZ spread of 2.65 V–2.75 V | Required where reference stability exceeds ±5 % error budget, e.g., precision ADC references | Select when regulation accuracy outweighs cost sensitivity; same package and thermal specs |
| MMSZ4678T1G | 2.7 V nominal, ±5 %, but in SOD-123 package (2.7 mm × 1.6 mm); 500 mW Ptot | Suitable for higher-power dissipation needs where board space allows larger footprint | Choose when thermal margin >365 mW is needed and SOD-123 layout is acceptable |
Compared with BZX884S-C2V7-QYL, BZX884S-B2V7-Q offers superior voltage accuracy at identical form factor, while MMSZ4678T1G trades miniaturization for higher power handling-enabling selection based on whether precision or thermal headroom dominates the design constraint.

FAQ
What is the maximum reverse current at 1 V for BZX884S-C2V7-QYL?
The maximum reverse current IR is 20 μA at VR = 1 V and Tj = 25 °C, as specified in Table 8 of the datasheet. This low leakage ensures minimal loading on high-impedance bias networks and preserves accuracy in sensor reference applications.
Can BZX884S-C2V7-QYL be used in reflow soldering processes?
Yes-Nexperia explicitly recommends reflow soldering only for the SOD882BD package. The device supports standard lead-free reflow profiles, and its side-wettable flanks are designed for reliable solder joint inspection using automated optical equipment.
How does the temperature coefficient affect regulation stability?
With a typical temperature coefficient of −3.5 mV/K, BZX884S-C2V7-QYL exhibits predictable negative drift: VZ decreases ~3.5 mV per Kelvin rise in junction temperature. This allows designers to compensate in firmware or select complementary components for zero-drift reference designs.
Is the marking "4L" confirmed for BZX884S-C2V7-QYL?
Yes-Table 4 confirms that BZX884S-C2V7-Q is marked "4L", and the QYL suffix denotes tape-and-reel packaging per Nexperia's ordering convention. The marking bar on the top surface identifies Pin 1 as the cathode terminal.
