Product details
Overview
RKZ6.8BKV from Renesas Electronics is a silicon planar Zener diode designed for precision voltage regulation in low-power analog and power-supply feedback circuits, with a nominal Zener voltage of 6.8 V (6.47–7.14 V), dynamic resistance of 30 Ω at 10 mA, and 700 mW power dissipation in the SRP-F surface-mount package. It operates within –55°C to +150°C storage range and supports stable reference generation in compact DC-DC converters.
For engineers reviewing the RKZ6.8BKV datasheet, RKZ6.8BKV pinout, RKZ6.8BKV application, or RKZ6.8BKV equivalent, this device serves as a high-stability, ESD-hardened (±30 kV per IEC 61000-4-2) Zener reference for voltage-clamping, overvoltage protection, and biasing in space-constrained industrial and consumer electronics.
Technical Context
The RKZ6.8BKV employs a planar junction structure optimized for tight Zener voltage tolerance (±5% at 10 mA) and low temperature coefficient (≈0.04 %/°C near 6.8 V). Its thermal design accommodates ambient temperatures up to +125°C with derated power dissipation per Fig.3.
It delivers consistent reverse breakdown behavior under pulsed test conditions (40 ms pulse width), with specified reverse current ≤2 μA at VR = 3.5 V and dynamic resistance measured at IZ = 10 mA - enabling predictable regulation in feedback loops and reference shunt paths.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C6V8 (Nexperia) | Same 6.8 V nominal, but 350 mW Pd and 40 Ω rd; SOT-23 package (larger footprint than SRP-F) | Lower power handling limits use in >200 mA shunt applications; less suitable for ultra-dense layouts | Select when cost sensitivity outweighs size and thermal performance requirements |
| MMSZ4688 (ON Semiconductor) | 6.8 V nominal, 500 mW Pd, 30 Ω rd, SOD-123 package (2.7 × 1.6 mm vs. RKZ6.8BKV's 2.5 × 1.2 mm) | Higher profile (1.1 mm) and larger area reduce suitability for sub-1 mm board gaps or stacked modules | Choose when legacy SOD-123 footprint compatibility is required over miniaturization |
Compared with BZX84-C6V8 and MMSZ4688, RKZ6.8BKV offers superior power density (700 mW in 3.0 mm²), lowest profile (0.6 mm), and identical dynamic resistance - making it optimal for next-generation wearables, IoT sensors, and multi-layer PCBs where vertical clearance and board area are constrained.

FAQ
What is the Zener voltage tolerance of RKZ6.8BKV at 10 mA?
The RKZ6.8BKV has a guaranteed Zener voltage range of 6.47 V to 7.14 V at IZ = 10 mA, corresponding to ±5% tolerance around the nominal 6.8 V rating. This specification is verified per REJ03G1700-0100 Rev.1.00 and applies under standard test conditions (Ta = 25°C, pulse width = 40 ms). The RKZ6.8BKV maintains this tolerance across its qualified operating temperature range.
Does RKZ6.8BKV support automatic optical inspection (AOI) after reflow?
Yes, RKZ6.8BKV features a laser-marked cathode indicator and standardized SRP-F package geometry (2.5 × 1.2 mm, 0.6 mm height) compatible with industry-standard AOI systems. The flat-lead terminations and consistent marking position (per Page 1 and Page 3 of REJ03G1700-0100) enable reliable solder-joint and polarity verification in high-speed SMT lines.
What is the maximum reverse current specification for RKZ6.8BKV at 3.5 V?
The RKZ6.8BKV specifies a maximum reverse current (IR) of 2 μA at VR = 3.5 V and Ta = 25°C, as confirmed in the Electrical Characteristics table on Page 2 of REJ03G1700-0100. This low leakage supports high-impedance reference nodes and minimizes quiescent power loss in battery-operated devices using RKZ6.8BKV.
Can RKZ6.8BKV be used in place of a 6.8 V Zener in an existing SOD-123 layout?
No - RKZ6.8BKV uses the SRP-F package (2.5 × 1.2 mm, 1.6 mm pin pitch), which is physically incompatible with SOD-123 footprints (2.7 × 1.6 mm, 2.5 mm pitch). Direct replacement would require PCB redesign. For SOD-123 compatibility, consider MMSZ4688 as an alternative, but note differences in thermal performance and height.
Is RKZ6.8BKV rated for automotive temperature ranges?
RKZ6.8BKV is qualified for storage from –55°C to +150°C and operates reliably up to Tj = 150°C. While not AEC-Q200 certified, its junction temperature rating and tested ESD performance (±30 kV) support use in non-safety-critical automotive subsystems such as infotainment power rails and body-control module sensors - provided system-level thermal design maintains Tj ≤ 150°C.
