Product details
Overview
BZX284-C10,115 from NXP Semiconductors is a ±5% 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, used for low-power voltage reference and regulation in space-constrained PCBs.
For engineers reviewing the BZX284-C10,115 datasheet, BZX284-C10,115 pinout, BZX284-C10,115 application, or BZX284-C10,115 equivalent, this part serves as a precision, surface-mount Zener solution where stable 10 V reference, low thermal resistance (315 K/W), and tight ±5% tolerance are required in industrial sensor interfaces, power supply feedback paths, and analog signal conditioning circuits.
Technical Context
The BZX284-C10,115 operates as a two-terminal silicon Zener diode with avalanche breakdown mechanism, optimized for stable reverse-bias regulation at 10 V. Its differential resistance is 20–150 Ω (typ./max. at 5 mA), and temperature coefficient is +6.4 mV/K - indicating positive drift with junction temperature rise.
Designed for operation at Tj = 25 °C (with derating above ambient), it supports continuous forward current up to 250 mA and withstands non-repetitive peak reverse surge currents of 3.0 A (100 μs square wave), with junction temperature limited to 150 °C and storage range from −65 °C to +150 °C.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBZ5240B | Same 10 V nominal, ±5%, but SOT-23 package (larger footprint, higher Rth j-a = 350 K/W) | Less suitable for ultra-dense layouts; higher thermal resistance limits power handling at elevated ambient | Select when SOT-23 reflow compatibility or legacy footprint reuse is prioritized over size |
| BZX84-C10 | Same 10 V/±5%, but plastic SOT-23 package and higher max leakage (500 nA @ 7 V) | Lower reliability in humid/high-temp environments due to plastic encapsulation and higher IR | Prefer for cost-sensitive, non-mission-critical consumer designs where moisture resistance is not required |
Compared with MMBZ5240B and BZX84-C10, the BZX284-C10,115 delivers superior thermal performance (315 K/W), lower leakage (200 nA), and ceramic hermeticity - making it optimal for industrial and automotive modules demanding long-term stability in variable climates.

FAQ
What is the nominal Zener voltage and test condition for BZX284-C10,115?
The BZX284-C10,115 has a nominal Zener voltage of 10 V, measured at a test current (IZ) of 5 mA and junction temperature of 25 °C. This value falls within the guaranteed range of 9.4 V to 10.6 V due to its ±5% tolerance. The BZX284-C10,115 is specified in Table 1 of the NXP datasheet under the "BZX284-C10" entry, confirming these parameters as production-tested values.
What package type does BZX284-C10,115 use and what are its key mechanical dimensions?
The BZX284-C10,115 uses the SOD110 surface-mount ceramic package, measuring 1.90 mm × 1.40 mm × 1.60 mm (L × W × H) with a cathode identification band. Its very small footprint and hermetic ceramic construction support high-reliability operation in humid or thermally cycling environments. The BZX284-C10,115's SOD110 outline is documented in the "PACKAGE OUTLINE" section (page 8) of the NXP datasheet.
What is the maximum reverse leakage current for BZX284-C10,115 and at what voltage is it specified?
The BZX284-C10,115 exhibits a maximum reverse leakage current of 200 nA, specified at a reverse voltage (VR) of 7 V and ambient temperature of 25 °C. This low leakage supports high-impedance bias networks and precision voltage dividers without introducing significant error current. The value is explicitly listed in the "ELECTRICAL CHARACTERISTICS" table on page 3 of the NXP datasheet under the BZX284-B/C10 row.
How does the temperature coefficient of BZX284-C10,115 affect its regulation performance?
The BZX284-C10,115 has a temperature coefficient of +6.4 mV/K, meaning its Zener voltage increases by approximately 6.4 mV for every 1 °C rise in junction temperature. This positive drift must be accounted for in wide-temperature-range applications; however, it enables predictable compensation in analog circuits. The coefficient is derived from Figure 4 in the NXP datasheet and confirmed in Table 1 for the BZX284-C10 variant.
Can BZX284-C10,115 be used in place of BZX284-B10 for higher precision applications?
No - the BZX284-C10,115 is not a substitute for BZX284-B10 in higher-precision applications, as it has ±5% tolerance versus BZX284-B10's tighter ±2%. The BZX284-B10 guarantees 9.80–10.20 V regulation, while BZX284-C10,115 allows 9.4–10.6 V. Using BZX284-C10,115 where BZX284-B10 is specified may introduce unacceptable voltage error in feedback or reference circuits requiring <±2% accuracy.
