Product details
Overview
BZX884D-B10 from Nexperia is a general-purpose Zener diode with a nominal 10 V regulation voltage (±2% tolerance at IZ = 5 mA), 250 mW power dissipation at Tamb = 25 °C, 200 mA forward current rating, and AEC-Q101 qualification for automotive-grade reliability - used in voltage reference and ESD protection circuits in mobile communication modules and digital camera power rails.
For engineers reviewing the BZX884D-B10 datasheet, BZX884D-B10 pinout, BZX884D-B10 application, or BZX884D-B10 equivalent, key selection criteria include its SOD882D ultra-thin (0.37 mm height) leadless package, low 200 nA reverse leakage at 7 V, 6.0 Ω typical differential resistance at 5 mA, and thermal resistance of 500 K/W in free air - critical for space-constrained, high-frequency biasing and clamping designs.
Technical Context
This Zener diode operates in reverse breakdown to maintain stable DC voltage across its terminals under varying load or supply conditions. Its 10 V nominal Zener voltage is specified at 5 mA test current with ±2% tolerance, and exhibits a positive temperature coefficient of +6.0 mV/K over 1–10 mA, enabling predictable drift compensation in precision references.
The device uses a planar silicon junction structure optimized for low noise and fast transient response, supporting ESD ultra-high-speed switching per IEC 61000-4-2 Level 4. Its 1.0 × 0.6 × 0.4 mm SOD882D package features solderable side pads and a cathode-marking bar for unambiguous orientation during automated placement.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 10.0 V ±2% at IZ = 5 mA - defines precise DC reference point for analog sensing or regulator feedback loops |
| Differential Resistance (rdiff) | 6.0 Ω typical at IZ = 5 mA - determines output impedance and load regulation sensitivity |
| Reverse Leakage (IR) | 200 nA max at VR = 7 V - ensures minimal quiescent current draw in standby-biased circuits |
| Power Dissipation (Ptot) | 250 mW at Tamb = 25 °C - sets maximum continuous bias power before thermal derating applies |
| Forward Voltage (VF) | 0.9 V max at IF = 10 mA - enables use as low-drop clamp or series bias diode in dual-role configurations |
| Thermal Resistance (Rth(j-a)) | 500 K/W in free air - dictates junction temperature rise under steady-state operation without heatsinking |
Pinout & Package
Encapsulated in the SOD882D (DFN1006D-2) leadless ultra-small plastic package: 2-terminal, body dimensions 1.0 × 0.6 × 0.4 mm, 0.37 mm typical height, with visible and solderable side pads. The cathode is marked by a bar on the top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to regulated output node; polarity marker (bar) aligns with this terminal for correct PCB orientation |
| 2 (A) | Anode | Connected to ground or lower-potential rail; reverse-biased configuration enables Zener conduction |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing - suitable for under-hood and infotainment power domains |
| SOD882D ultra-thin package | 0.37 mm height and 1.0 × 0.6 mm footprint - enables integration into ultra-dense mobile PCBs where SOT23 is too tall |
| Low differential resistance | 6.0 Ω typical at 5 mA - improves regulation stability against load transients in sensor bias networks |
| ESD ultra-high-speed switching | Capable of clamping sub-ns transients per IEC 61000-4-2 Level 4 - protects high-speed data lines in camera interfaces and USB PHYs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX884D-B10,115 | Same electrical specs and SOD882D package; differs only in tape-and-reel packaging (10,000 pcs/reel vs. 3,000 pcs/reel) | No functional difference; identical performance in circuit | Select for volume production requiring standard reel size compatibility with pick-and-place feeders |
| MMSZ4689T1G | 10 V Zener, ±5% tolerance, SOD-123 package (1.8 × 1.4 × 1.0 mm), 500 mW Ptot, higher rdiff (15 Ω) | Larger footprint and looser tolerance; better suited for non-critical bulk regulation | Choose when board space allows larger package and ±5% regulation is acceptable for cost-sensitive consumer designs |
Compared with BZX884D-B10, the BZX884D-B10,115 offers identical electrical behavior with different packaging logistics, while MMSZ4689T1G trades tighter tolerance and smaller size for higher power handling and relaxed accuracy - making the original optimal for space-constrained, precision-clamping roles.

FAQ
What is the maximum reverse voltage the BZX884D-B10 can withstand before breakdown?
The BZX884D-B10 is designed to operate in controlled reverse breakdown at its nominal Zener voltage of 10.0 V ±2%. Its absolute maximum reverse voltage is not defined separately - instead, the device must be operated within its limiting values: peak reverse current IZSM ≤ 110 A for 100 µs pulses, and total power dissipation ≤250 mW at 25 °C ambient. Exceeding these causes permanent damage.
Can the BZX884D-B10 be used in forward-bias applications?
Yes - the BZX884D-B10 has a forward voltage of ≤0.9 V at 10 mA, making it usable as a low-drop rectifier or series bias diode. However, its primary design intent is reverse-bias Zener regulation; forward characteristics are secondary and not optimized for high-current switching or low-VF efficiency.
How does the SOD882D package affect thermal performance compared to SOT23?
The SOD882D package delivers comparable power dissipation (250 mW) to SOT23 but achieves it with significantly reduced height (0.37 mm vs. ~1.1 mm) and footprint area. Its thermal resistance is 500 K/W in free air - higher than typical SOT23 (~300 K/W) due to smaller copper pad area, requiring careful PCB layout with thermal vias if operating near Ptot limits.
Is the BZX884D-B10 suitable for automotive power supply designs?
Yes - it is explicitly AEC-Q101 qualified, tested for temperature cycling, high-temperature reverse bias, and ESD robustness per automotive standards. It is approved for use in non-safety-critical automotive subsystems such as infotainment, telematics, and body electronics, provided junction temperature remains ≤150 °C and ambient stays within −55 °C to +150 °C.
