Product details
Overview
BZX284-C5V6,135 from NXP Semiconductors is a ±5% tolerance Zener voltage regulator diode in a SOD110 ceramic SMD package, rated for 5.6 V nominal working voltage at 5 mA test current, 400 mW total power dissipation, and 12 A non-repetitive peak reverse surge current. 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-C5V6,135 datasheet, BZX284-C5V6,135 pinout, BZX284-C5V6,135 application, or BZX284-C5V6,135 equivalent, this part delivers verified Zener regulation performance with documented differential resistance (80–400 Ω), temperature coefficient (+1.2 mV/K), and reverse leakage (1 μA at 2 V) - critical for stable biasing and low-drift reference design.
Technical Context
The BZX284-C5V6,135 operates as a two-terminal silicon Zener diode optimized for low-current regulation (IZtest = 5 mA) and exhibits a positive temperature coefficient of +1.2 mV/K, indicating increasing breakdown voltage with junction temperature - a key behavior for thermal compensation in reference circuits. Its differential resistance of 80 Ω (typical) at 5 mA enables predictable dynamic impedance in shunt regulation topologies.
Designed for surface-mount integration on standard PCBs (11 × 25 × 1.6 mm), it leverages ceramic SOD110 packaging to achieve low parasitic capacitance (275 pF at 0 V) and high thermal resistance (315 K/W), making it suitable for space-constrained, low-power applications where stability under ambient temperature variation is required.
Key Specifications

What is the nominal Zener voltage and test condition for BZX284-C5V6,135?
The BZX284-C5V6,135 has a nominal Zener voltage of 5.6 V measured at a test current (IZtest) of 5 mA, with a guaranteed tolerance of ±5%. This value is specified under junction temperature conditions of 25 °C and forms the basis for its use in precision voltage reference and clamping applications where predictable breakdown behavior is essential.
What is the maximum continuous power dissipation for BZX284-C5V6,135?
The BZX284-C5V6,135 has a maximum total power dissipation (Ptot) of 400 mW at ambient temperature (Tamb) of 25 °C when mounted on a standard 11 × 25 × 1.6 mm PCB. Derating applies above 25 °C at 1.27 mW/°C based on its thermal resistance of 315 K/W, ensuring safe operation in real-world thermal environments.
Does BZX284-C5V6,135 have a positive or negative temperature coefficient?
The BZX284-C5V6,135 exhibits a positive temperature coefficient of +1.2 mV/K at IZ = 5 mA, meaning its Zener voltage increases linearly with rising junction temperature. This characteristic is confirmed in Figure 4 of the NXP datasheet and must be accounted for in temperature-sensitive reference designs.
What is the reverse leakage current specification for BZX284-C5V6,135?
The BZX284-C5V6,135 specifies a maximum reverse leakage current (IR) of 1 μA at VR = 2 V, measured at Tj = 25 °C. This low leakage supports high-impedance bias networks and minimizes error in precision voltage divider configurations used with the BZX284-C5V6,135.
What package type does BZX284-C5V6,135 use and what are its key mechanical dimensions?
The BZX284-C5V6,135 uses the SOD110 very small ceramic SMD package, measuring 2.10 mm in length, 1.40 mm in width, and 1.60 mm in height. Its ceramic construction provides superior thermal stability and moisture resistance compared to plastic alternatives, and the cathode is marked by a visible band on the top surface.
