Product details
Overview
BZX284-C16,115 from NXP Semiconductors is a ±5% tolerance Zener voltage regulator diode in a SOD110 ceramic SMD package, rated for 16 V nominal working voltage at 5 mA test current, 400 mW total power dissipation, and 25 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-C16,115 datasheet, BZX284-C16,115 pinout, BZX284-C16,115 application, or BZX284-C16,115 equivalent, key selection criteria include its ±5% voltage tolerance, 12.4 V minimum reverse breakdown voltage under surge conditions, 97 pF diode capacitance at 0 V, and suitability for space-constrained SMD designs requiring stable regulation below 400 mW.
Technical Context
This device operates as a two-terminal silicon Zener diode optimized for low-current voltage regulation and reference functions. Its breakdown mechanism is predominantly Zener-dominated below 5.6 V and avalanche-dominated above - for BZX284-C16,115 (16 V), avalanche conduction governs its stable reverse-bias behavior with 4 mV/K positive temperature coefficient and 25–200 Ω max differential resistance across operating current range.
The SOD110 package enables high thermal resistance (315 K/W junction-to-ambient) but supports reliable operation up to 150 °C junction temperature. Reverse leakage remains ≤50 nA at 0.7 × VZnom (11.2 V), and non-repetitive peak reverse current reaches 1.5 A for 100 μs pulses - critical for transient suppression in low-energy circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Zener Voltage (VZ) | 16 V at IZtest = 5 mA - defines primary regulation point for feedback or reference use |

| Diode Capacitance (Cd) | 97 pF at f = 1 MHz, VR = 0 V - impacts high-frequency noise filtering and AC coupling performance |
| Thermal Resistance (Rth j-a) | 315 K/W - requires careful thermal layout for sustained operation near power limit |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBZ5245BS-7-F | 16 V ±5%, SOT-23 package, 200 mW Ptot, 100 Ω rdiff | Lower power rating and higher impedance reduce regulation stability under varying load | Select when board space allows SOT-23 and thermal budget is constrained |

The BZX284-C16,115 has a nominal Zener voltage of 16 V measured at a test current (IZtest) of 5 mA, with a guaranteed range of 15.3 V to 17.1 V due to its ±5% tolerance. This specification is valid at Tj = 25 °C and forms the basis for all downstream regulation accuracy calculations in circuit design.
What is the maximum continuous power dissipation for BZX284-C16,115?
BZX284-C16,115 has a maximum total power dissipation (Ptot) of 400 mW at ambient temperature of 25 °C, as defined in the Absolute Maximum Ratings table. Derating is required above 25 °C per the specified thermal resistance of 315 K/W, reaching zero dissipation at approximately 125 °C ambient.
Does BZX284-C16,115 have a specified junction capacitance, and what is its value?
Yes, BZX284-C16,115 has a typical junction capacitance (Cd) of 97 pF measured at 1 MHz and zero applied reverse voltage (VR = 0 V). This value is critical for high-frequency applications such as RF biasing or fast transient clamping where capacitive loading must be minimized.
What is the reverse leakage current specification for BZX284-C16,115 at its rated voltage?
At a reverse voltage of 11.2 V (0.7 × VZnom = 0.7 × 16 V), the BZX284-C16,115 exhibits a maximum reverse leakage current (IR) of 50 nA. This ultra-low leakage supports high-impedance reference networks and battery-operated circuits where standby current must remain sub-microamp.
