Product details
Overview
BZX284-C7V5,115 from NXP Semiconductors is a ±5% tolerance Zener voltage regulator diode in a SOD110 ceramic SMD package, rated for 7.5 V nominal working voltage at 5 mA test current, 400 mW total power dissipation, and 1 μA reverse current at 5 V reverse bias. It serves as a precision low-power reference or clamp in power supply feedback paths, sensor biasing circuits, and overvoltage protection stages.
For engineers reviewing the BZX284-C7V5,115 datasheet, BZX284-C7V5,115 pinout, BZX284-C7V5,115 application, or BZX284-C7V5,115 equivalent, key selection criteria include its 7.35–7.65 V Zener voltage range, 15–80 Ω differential resistance at 5 mA, +4.0 mV/K temperature coefficient, SOD110 footprint compatibility, and suitability for space-constrained industrial and consumer voltage regulation.
Technical Context
The BZX284-C7V5,115 operates as a two-terminal silicon Zener diode with controlled reverse breakdown behavior. Its junction exhibits a positive temperature coefficient of +4.0 mV/K at 5 mA, indicating increasing Zener voltage with rising temperature - a characteristic critical for thermal stability in bias networks.
Designed for surface-mount assembly on standard PCBs (11 × 25 × 1.6 mm), it delivers stable regulation under continuous forward current up to 250 mA and withstands non-repetitive peak reverse surges up to 4.0 A (100 μs pulse), supporting transient suppression in low-energy signal lines.

FAQ
What is the Zener voltage tolerance of the BZX284-C7V5,115?
The BZX284-C7V5,115 has a ±5% Zener voltage tolerance, meaning its nominal 7.5 V breakdown voltage falls within the 7.35 V to 7.65 V range when measured at 5 mA test current and 25 °C junction temperature. This tolerance is confirmed in Table 1 of the NXP datasheet and applies specifically to the 'C' series variant of the BZX284 family.
Does the BZX284-C7V5,115 have a specified thermal resistance?
Yes, the BZX284-C7V5,115 has a thermal resistance from junction to ambient (Rth j-a) of 315 K/W when mounted on a standard 11 × 25 × 1.6 mm PCB, as stated in the Thermal Characteristics section of the NXP datasheet. This value is critical for calculating junction temperature rise under steady-state power dissipation.
What is the reverse leakage current specification for the BZX284-C7V5,115?
The BZX284-C7V5,115 exhibits a maximum reverse current (IR) of 1 μA at VR = 5 V, as specified in the Electrical Characteristics table. This low leakage supports energy-efficient operation in battery-powered and always-on monitoring circuits where standby current must be minimized.
Can the BZX284-C7V5,115 be used in place of a BZX284-B7V5?
No - the BZX284-C7V5,115 is not a direct replacement for the BZX284-B7V5 because they differ in voltage tolerance: the 'C' version is ±5%, while the 'B' version is ±2%. Although both share identical package, pinout, and basic electrical structure, the tighter tolerance of the BZX284-B7V5 makes it unsuitable for applications requiring the looser tolerance and associated cost benefit of the BZX284-C7V5,115.
What is the differential resistance of the BZX284-C7V5,115 at its rated test current?
The differential resistance (rdiff) of the BZX284-C7V5,115 is specified as 15 Ω minimum and 80 Ω maximum at IZ = 5 mA and Tj = 25 °C, per Table 1 in the NXP datasheet. This parameter directly affects regulation accuracy under varying load conditions and must be considered when designing feedback networks.
