Product details
Overview
BZX284-B9V1,115 from NXP Semiconductors is a ±2% tolerance Zener voltage regulator diode in a SOD110 ceramic SMD package, rated for 9.1 V nominal working voltage at 5 mA test current, 400 mW total power dissipation, and 20 Ω typical differential resistance at 5 mA. It serves as a precision low-power voltage reference in power supply feedback paths, overvoltage clamping circuits, and analog signal conditioning stages.
For engineers reviewing the BZX284-B9V1,115 datasheet, BZX284-B9V1,115 pinout, BZX284-B9V1,115 application, or BZX284-B9V1,115 equivalent, this page delivers verified electrical parameters, thermal behavior, SOD110 package dimensions, reverse leakage at 6 V (500 nA), and temperature coefficient (+5.5 mV/K), supporting accurate circuit modeling and board-level reliability assessment.
Technical Context
The BZX284-B9V1,115 operates as a silicon planar Zener diode with avalanche breakdown mechanism above 6 V, exhibiting +5.5 mV/K temperature coefficient at IZ = 5 mA and 20–100 Ω differential resistance range depending on test current. Its junction-to-ambient thermal resistance is 315 K/W when mounted on a 11 × 25 × 1.6 mm PCB.
Designed for stable DC voltage regulation under low-current conditions, it maintains 8.92–9.28 V Zener voltage tolerance across the ±2% band, with reverse leakage limited to 500 nA at VR = 6 V and junction temperature up to 150 °C. The SOD110 package enables high-density placement while sustaining 12 A non-repetitive peak reverse surge capability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX284-C9V1,115 | ±5% tolerance (9.1 V ±0.455 V), same SOD110 package and 400 mW rating | Acceptable where tighter regulation is not required; higher unit cost not justified | Select BZX284-C9V1,115 only if system-level testing confirms ±5% Zener variation meets functional margin |
| MMSZ4687T1G | ±5% tolerance, 9.1 V nominal, SOD123 package, 500 mW rating, 30 Ω rdif at 5 mA | Larger footprint and higher power handling; less suitable for ultra-dense layouts | Choose MMSZ4687T1G when higher surge current capability or legacy SOD123 board compatibility is needed |
Compared with BZX284-B9V1,115, the BZX284-C9V1,115 trades voltage precision for broader tolerance acceptance, while MMSZ4687T1G offers higher power but sacrifices board space efficiency and ceramic package stability.

FAQ
What is the nominal Zener voltage and test condition for BZX284-B9V1,115?
The BZX284-B9V1,115 has a nominal Zener voltage of 9.1 V measured at a test current of 5 mA. This value falls within the guaranteed range of 8.92 V to 9.28 V at 25 °C, reflecting its ±2% tolerance specification. The BZX284-B9V1,115 achieves this regulation through controlled avalanche breakdown in its silicon junction.
What is the maximum power dissipation rating for BZX284-B9V1,115 and under what conditions?
The BZX284-B9V1,115 is rated for a maximum total power dissipation of 400 mW at an ambient temperature of 25 °C, assuming mounting on a standard 11 × 25 × 1.6 mm PCB. Derating is required above 25 °C at 1.27 mW/°C based on its 315 K/W junction-to-ambient thermal resistance. The BZX284-B9V1,115 must not exceed this limit to prevent thermal runaway or parametric shift.
Does BZX284-B9V1,115 have a specified reverse leakage current, and at what voltage is it measured?
Yes, the BZX284-B9V1,115 specifies a maximum reverse leakage current of 500 nA at VR = 6 V and Tamb = 25 °C. This low leakage supports high-impedance circuit operation and minimizes standby power consumption. The BZX284-B9V1,115 maintains this performance across its qualified operating temperature range without degradation.
What is the temperature coefficient of BZX284-B9V1,115 and how does it affect regulation stability?
The BZX284-B9V1,115 exhibits a positive temperature coefficient of +5.5 mV/K at IZ = 5 mA, meaning its Zener voltage increases linearly with junction temperature. This characteristic enables predictable drift modeling in temperature-compensated designs. The BZX284-B9V1,115's coefficient is consistent across production lots and remains stable over its 150 °C maximum junction temperature rating.
Which package type does BZX284-B9V1,115 use and what are its key mechanical dimensions?
The BZX284-B9V1,115 uses the SOD110 very small ceramic surface-mount package, with overall dimensions of 2.10 mm length × 1.40 mm width × 1.60 mm height. Its cathode is marked by a band on the top surface, and it complies with JEDEC outline standards for automated placement. The BZX284-B9V1,115's ceramic construction provides enhanced moisture resistance and long-term parameter stability versus plastic alternatives.
