Product details
Overview
BZX884-B3V3,315 from Nexperia is a ±2% tolerance Zener diode in SOD882 (DFN1006-2) package, rated for 3.3 V nominal regulation at 5 mA, with 250 mW total power dissipation and 5 µA reverse current at VR = 1 V. It serves as a precision voltage reference or low-power shunt regulator in space-constrained consumer and automotive electronics.
For engineers reviewing the BZX884-B3V3,315 datasheet, BZX884-B3V3,315 pinout, BZX884-B3V3,315 application, or BZX884-B3V3,315 equivalent, key selection criteria include its 3.23–3.37 V Zener voltage range, 350–500 Ω differential resistance at 1 mA, −1.8 mV/K temperature coefficient, and AEC-Q101 qualification for automotive use.
Technical Context
This Zener diode operates in reverse breakdown to maintain stable voltage across load variations, with specified regulation at IZ = 5 mA and test conditions defined per IEC 60134 limiting values. Its ultra-small DFN1006-2 footprint enables high-density PCB layouts while maintaining thermal resistance of 500 K/W in free air.
The device exhibits a negative temperature coefficient of −1.8 mV/K at IZ = 5 mA, ensuring predictable drift over temperature, and achieves 410 pF capacitance at 1 MHz and 0 V reverse bias-critical for ESD clamping and high-frequency bypass applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 3.23–3.37 V at IZ = 5 mA; defines tight regulation window for low-voltage rail stabilization |
| Differential Resistance (rdiff) | 350–500 Ω at IZtest = 1 mA; determines output impedance and load regulation sensitivity |
| Reverse Current (IR) | 5 µA max at VR = 1 V; ensures low leakage in standby or battery-powered circuits |
| Power Dissipation (Ptot) | 250 mW at Tamb ≤ 25 °C on FR4 PCB; sets maximum continuous power handling under standard layout |
| Temperature Coefficient (SZ) | −1.8 mV/K at IZ = 5 mA; quantifies voltage drift per degree Celsius for thermal design margining |
| Package | SOD882 (DFN1006-2); 1.0 × 0.6 × 0.5 mm leadless surface-mount package enabling <0.6 mm² board area usage |
| AEC-Q101 Qualified | Validated for automotive-grade reliability including temperature cycling, humidity, and mechanical stress testing |
Pinout & Package
SOD882 (DFN1006-2) is a 2-terminal, leadless ultra-small plastic package with exposed cathode marking bar on top surface. Body dimensions are 1.0 mm × 0.6 mm × 0.5 mm; terminals are co-planar and soldered directly to PCB pads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to regulated output node; marking bar identifies this terminal for correct orientation during placement |
| 2 | Anode (A) | Connected to ground or lower-potential reference; completes reverse-bias path for Zener conduction |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBZ5226BS-7-F | ±5% tolerance, 3.3 V nominal, SOT-323 package (2.1 × 1.3 mm), 350 mW rating | Larger footprint and looser tolerance; higher power but less precision | Select when cost priority outweighs size and regulation accuracy; not AEC-Q101 qualified |
| BZX384-B3V3,115 | Same ±2% tolerance and 3.3 V rating, but SOD-323 package (1.7 × 1.3 mm), 300 mW rating | 2.8× larger PCB area; higher thermal mass improves surge handling but limits density | Choose for legacy board compatibility or where reflow yield favors larger pad geometry |
Compared with BZX884-B3V3,315, MMBZ5226BS-7-F trades precision and miniaturization for cost and power margin, while BZX384-B3V3,115 retains tolerance and voltage accuracy but sacrifices 70% board area efficiency-making the BZX884-B3V3,315 optimal for next-gen compact automotive and portable designs.

FAQ
What is the maximum reverse current for BZX884-B3V3,315 at 1 V reverse bias?
The maximum reverse current is 5 µA at VR = 1 V and Tj = 25 °C, as specified in Table 7 of the datasheet. This low leakage supports energy-efficient operation in battery-powered systems where standby current must remain below 10 µA.
Is BZX884-B3V3,315 suitable for ESD protection in high-speed data lines?
Yes-it delivers 410 pF capacitance at 1 MHz and 0 V bias, enabling effective clamping of IEC 61000-4-2 ESD transients on USB 2.0 and I²C lines without distorting signal edges, provided series impedance is properly designed to limit peak current.
How does the −1.8 mV/K temperature coefficient affect regulation stability?
At IZ = 5 mA, the Zener voltage decreases by 1.8 mV per °C rise in junction temperature. Over a −40 °C to +125 °C range, this results in ~300 mV total drift-acceptable for non-critical biasing but requires compensation in precision references.
Can BZX884-B3V3,315 be used in place of a 3.3 V LDO for power regulation?
No-it functions only as a shunt regulator, requiring a series current-limiting resistor and dissipating excess power as heat. Unlike an LDO, it cannot source load current or maintain regulation under variable load; it is intended for reference, biasing, or protection-not primary power conversion.
