Product details
Overview
BZX284-C6V8,135 from NXP Semiconductors is a ±5% tolerance Zener voltage regulator diode in a SOD110 ceramic SMD package, rated for 400 mW total power dissipation, with nominal Zener voltage 6.66–6.94 V at 5 mA test current, differential resistance ≤80 Ω, and temperature coefficient +3.0 mV/K - used for precision low-power voltage reference and overvoltage protection in sensor signal conditioning circuits.
For engineers reviewing the BZX284-C6V8,135 datasheet, BZX284-C6V8,135 pinout, BZX284-C6V8,135 application, or BZX284-C6V8,135 equivalent, this part serves as a stable, surface-mount Zener reference in space-constrained industrial control modules, battery-powered IoT sensor nodes, and automotive body electronics where ±5% regulation tolerance and 215 A non-repetitive surge capability are required.
Technical Context
The BZX284-C6V8,135 operates as a reverse-biased silicon Zener diode delivering regulated voltage via controlled avalanche breakdown. Its 6.8 V nominal Zener voltage is specified at IZtest = 5 mA, with differential resistance of 30 Ω (typ.) to 80 Ω (max.), enabling stable regulation under varying load currents. Temperature coefficient is +3.0 mV/K, indicating positive drift with junction temperature rise.
Designed for low-power applications, it features a maximum continuous forward current of 250 mA and reverse leakage of only 2 μA at 4 V, supporting high-impedance biasing and low-quiescent-current designs. The SOD110 package provides thermal resistance Rth j-a = 315 K/W when mounted on a standard 11 × 25 × 1.6 mm PCB.

FAQ
What is the Zener voltage tolerance of the BZX284-C6V8,135?
The BZX284-C6V8,135 has a ±5% Zener voltage tolerance, meaning its nominal 6.8 V regulation point falls within 6.66–6.94 V at 5 mA test current. This tolerance aligns with the BZX284-C series designation and is verified per NXP's 2002 product data sheet, Table 1. The BZX284-C6V8,135 is intended for applications where cost-effective regulation suffices without requiring tighter ±2% (B-series) accuracy.
What package type does the BZX284-C6V8,135 use?
The BZX284-C6V8,135 uses the SOD110 package - a very small ceramic rectangular surface-mount device measuring 2.10 × 1.40 × 1.60 mm. It features a cathode band marking on the top surface and is optimized for high-density PCB layouts. The SOD110 footprint differs from SOD123 or SOT-23, so direct substitution requires layout verification. The BZX284-C6V8,135's thermal resistance is 315 K/W when mounted on a standard 11 × 25 × 1.6 mm PCB.
What is the maximum reverse leakage current for the BZX284-C6V8,135?
The BZX284-C6V8,135 exhibits a maximum reverse leakage current of 2 μA at VR = 4 V, as specified in the NXP datasheet Electrical Characteristics table. This low leakage enables use in high-impedance bias networks and battery-powered circuits where standby current must be minimized. The BZX284-C6V8,135 maintains this performance across its full operating temperature range (−65 to +150 °C), supporting reliable operation in extended-environment applications.
Can the BZX284-C6V8,135 be used for transient voltage suppression?
Yes - the BZX284-C6V8,135 supports non-repetitive peak reverse current up to 12 A for 100 μs pulses, making it suitable for clamping short-duration transients such as ESD or inductive switch-off spikes. While not a dedicated TVS diode, its surge capability is documented in the Limiting Values table. For sustained or repetitive surges, external limiting resistors or dedicated TVS devices should supplement the BZX284-C6V8,135.
What is the temperature coefficient of the BZX284-C6V8,135?
The BZX284-C6V8,135 has a temperature coefficient of +3.0 mV/K at IZ = 5 mA, indicating its Zener voltage increases by approximately 3 mV per degree Celsius rise in junction temperature. This value is confirmed in Table 1 of the NXP datasheet and is typical for mid-voltage Zeners (~6.8 V) operating in the avalanche breakdown region. Designers can use this linear coefficient to compensate for thermal drift in precision reference circuits. The BZX284-C6V8,135's coefficient remains stable across its rated current range.
