Product details
Overview
BZX284-C6V8,115 from NXP Semiconductors is a ±5% tolerance Zener voltage regulator diode in a SOD110 ceramic SMD package, rated for 400 mW total power dissipation at 25 °C ambient, 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 low-power voltage reference and overvoltage protection in sensor signal conditioning circuits.
For engineers reviewing the BZX284-C6V8,115 datasheet, BZX284-C6V8,115 pinout, BZX284-C6V8,115 application, or BZX284-C6V8,115 equivalent, this page delivers verified electrical parameters, thermal behavior, SOD110 package dimensions, reverse leakage (2 µA at 4 V), and direct alternative part comparisons to support precision analog design and BOM validation.
Technical Context
The BZX284-C6V8,115 operates as a two-terminal silicon Zener diode optimized for stable voltage regulation in low-current (<10 mA) bias conditions. Its Zener breakdown mechanism provides predictable reverse conduction onset at 6.66–6.94 V, with low dynamic impedance (30–80 Ω) ensuring minimal output voltage shift under load variation.
Thermal resistance from junction to ambient is 315 K/W when mounted on a standard 11 × 25 × 1.6 mm PCB, limiting maximum steady-state power dissipation to 400 mW at 25 °C ambient. Reverse leakage remains tightly controlled at 2 µA @ VR = 4 V, supporting reliable clamping in precision feedback paths.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBZ5235B-7-F | Same 6.8 V nominal, ±5%, but in SOT-23 package (larger footprint, higher rdiff = 130 Ω) | Higher thermal resistance (400 K/W) limits power handling in compact layouts | Select when SOT-23 is already standardized in design and 130 Ω rdiff is acceptable |
| BZX84-C6V8,215 | Same 6.8 V, ±5%, but in smaller SOD-323 package (1.7 × 1.3 × 0.9 mm) and lower Ptot = 300 mW | Lower power rating restricts use to sub-5 mA bias conditions | Select when board space is critical and thermal load is <300 mW |
Compared with BZX284-C6V8,115, MMBZ5235B-7-F offers broader distributor availability but sacrifices thermal performance and dynamic impedance; BZX84-C6V8,215 reduces footprint by 40% but requires derating below 300 mW - making BZX284-C6V8,115 optimal for 400 mW, low-rdiff, and high-reliability SOD110 deployments.

FAQ
What is the Zener voltage tolerance of BZX284-C6V8,115?
The BZX284-C6V8,115 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 is confirmed in Table 1 of the NXP datasheet and applies specifically to the "C" series variant. The BZX284-C6V8,115 maintains this specification across its full operating temperature range and is validated for production use in commercial and industrial environments.
What package type does BZX284-C6V8,115 use?
The BZX284-C6V8,115 uses the SOD110 very small ceramic surface-mount package, measuring 2.10 × 1.40 × 1.60 mm with a cathode marking on the top surface. This package is distinct from plastic SMD variants like SOD-323 or SOT-23 and is specified in the NXP outline drawing 97-04-14. Its ceramic construction provides superior thermal stability and moisture resistance compared to epoxy packages.
What is the maximum reverse leakage current for BZX284-C6V8,115?
The maximum reverse leakage current for BZX284-C6V8,115 is 2 µA at VR = 4 V, as stated in the Electrical Characteristics table of the NXP datasheet. This value is measured at Tj = 25 °C and reflects the device's ability to minimize parasitic current in high-impedance reference circuits - a key parameter for precision analog designs relying on the BZX284-C6V8,115 as a voltage clamp or bias source.
Can BZX284-C6V8,115 be used in automotive applications?
Yes, BZX284-C6V8,115 is suitable for automotive cabin control applications due to its −65 to +150 °C junction temperature range and qualification per IEC 60134 limiting values. While not AEC-Q200 qualified out-of-box, its ceramic SOD110 package and thermal robustness support use in non-safety-critical subsystems such as display backlight biasing and sensor interface clamping - provided system-level testing validates performance under load-dump and temperature cycling per ISO 16750.
What is the differential resistance of BZX284-C6V8,115 at 5 mA?
The differential resistance (rdiff) of BZX284-C6V8,115 is ≤80 Ω at IZ = 5 mA, as specified in Table 1 of the NXP datasheet. This parameter directly impacts regulation accuracy under varying load conditions: lower rdiff means less voltage deviation for a given change in Zener current. For the BZX284-C6V8,115, this value enables stable reference generation in low-noise analog signal chains where voltage ripple must remain below 1 mV.
