Product details
Overview
BZX284-B10,115 from NXP Semiconductors is a ±2% tolerance Zener voltage regulator diode in a SOD110 ceramic SMD package, rated for 10 V nominal working voltage at 5 mA test current, 400 mW total power dissipation, and 200 nA reverse leakage at 7 V. It serves as a precision low-power voltage reference in power supply feedback paths, sensor biasing circuits, and overvoltage protection clamps.
For engineers reviewing the BZX284-B10,115 datasheet, BZX284-B10,115 pinout, BZX284-B10,115 application, or BZX284-B10,115 equivalent, this device is selected for stable 10 V regulation in space-constrained SMD designs requiring tight voltage tolerance, low thermal resistance (315 K/W), and verified differential resistance of ≤150 Ω at 5 mA.
Technical Context
The BZX284-B10,115 operates as a two-terminal silicon Zener diode with avalanche breakdown mechanism optimized for stable reverse-bias regulation. Its 10 V nominal Zener voltage is specified at IZtest = 5 mA, with temperature coefficient of +6.4 mV/K and typical differential resistance of 20 Ω at 5 mA - enabling predictable regulation across industrial temperature ranges.
Designed for surface-mount use on standard PCBs (11 × 25 × 1.6 mm), it delivers 400 mW power handling at 25 °C ambient, with junction temperature limited to 150 °C and storage range from −65 °C to +150 °C. Reverse leakage remains below 200 nA at 7 V, supporting low-quiescent-current applications.
Key Specifications

|---|---|---|
| Anode (A) | Forward conduction terminal | Connected to lower potential side in Zener regulation; carries forward current up to 250 mA |
| Cathode (K) | Zener breakdown terminal | Connected to higher potential side; establishes 10 V reference when reverse-biased above breakdown |

FAQ
What is the nominal Zener voltage and test condition for BZX284-B10,115?
The BZX284-B10,115 has a nominal Zener voltage of 10 V, specified at a test current of 5 mA (IZtest = 5 mA). This value falls within the min/max range of 9.80 V to 10.20 V per the ±2% tolerance. The device maintains this regulation point across its operational temperature range and is validated in Table 1 of the NXP datasheet.
What is the maximum power dissipation of BZX284-B10,115 and under what conditions?
The BZX284-B10,115 has a maximum total power dissipation of 400 mW at an ambient temperature of 25 °C, as stated in the Limiting Values table. Derating applies above 25 °C per the thermal resistance of 315 K/W - for example, at 70 °C ambient, usable power drops to approximately 260 mW to maintain safe junction temperature.
Does BZX284-B10,115 have a specified reverse leakage current, and at what voltage?
Yes, the BZX284-B10,115 has a maximum reverse leakage current of 200 nA at VR = 7 V, as confirmed in the Electrical Characteristics table. This low leakage supports high-impedance applications such as precision voltage dividers and battery-operated sensor biasing where quiescent current must be minimized.
What package type does BZX284-B10,115 use, and what are its key mechanical dimensions?
The BZX284-B10,115 uses the SOD110 very small ceramic SMD package, measuring 2.10 mm × 1.40 mm × 1.60 mm (L × W × H). Its cathode is marked by a band on one end, and it is designed for reflow soldering on standard PCBs per the outline drawing in the NXP datasheet revision 97-04-14.
How does the temperature coefficient of BZX284-B10,115 affect its regulation stability?
The BZX284-B10,115 has a positive temperature coefficient of +6.4 mV/K at IZ = 5 mA, meaning its Zener voltage increases by ~6.4 mV per degree Celsius rise. This behavior is well-characterized and predictable, allowing designers to compensate in systems requiring tight regulation across −40 °C to +125 °C operating ranges.
