Product details
Overview
RKZ6.2BKV 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 6.2 V, dynamic resistance of 50 Ω at 10 mA, maximum power dissipation of 700 mW, and ESD capability of ±30 kV (HBM), commonly used in voltage reference and overvoltage protection stages of DC-DC converters.
For engineers reviewing the RKZ6.2BKV datasheet, RKZ6.2BKV pinout, RKZ6.2BKV application, or RKZ6.2BKV equivalent, this device is selected for stable 6.2 V clamping in compact SMT designs where thermal derating, low leakage, and high ESD robustness are critical - especially in industrial sensor interfaces and automotive body electronics.
Technical Context
The RKZ6.2BKV operates as a two-terminal voltage reference device using silicon planar junction technology, optimized for surface-mount applications in the SRP-F flat-lead package. Its zener voltage is specified at 5.86–6.53 V under 10 mA test current, with temperature coefficient near zero crossing around 6.2 V, enabling minimal drift across ambient temperatures.
It exhibits reverse breakdown behavior with tightly controlled dynamic resistance (50 Ω max at 10 mA) and low reverse leakage (≤2 µA at VR = 3 V), supporting accurate regulation in shunt configuration. The device meets JEITA package standard PWSF0002ZB-A and is rated for junction temperatures up to 150°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 5.86–6.53 V at IZ = 10 mA - defines precise clamping threshold for feedback loops |
| Dynamic Resistance (rd) | 50 Ω max at IZ = 10 mA - ensures minimal output voltage variation under load transients |
| Power Dissipation (Pd) | 700 mW at Ta = 25°C on 50×50 mm PCB - sets thermal design margin for board-level layout |
| Reverse Leakage (IR) | ≤2 µA at VR = 3 V - guarantees low quiescent current in standby regulation circuits |
| ESD Capability | ±30 kV HBM (C = 150 pF, R = 330 Ω) - enables robust operation in handling-sensitive industrial environments |
| Junction Temperature (Tj) | −55 to +150°C - supports extended-range operation in automotive cabin and industrial control enclosures |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C6V2 (Nexperia) | Same 6.2 V nominal VZ, but 300 mW Pd, 100 Ω rd, SOT-23 package (larger footprint, higher profile) | Limited to lower-power regulation; unsuitable for >150 mW continuous dissipation | Select when board space allows SOT-23 and thermal budget is constrained below 300 mW |
| MMSZ4687 (ON Semiconductor) | 6.2 V VZ, 500 mW Pd, 60 Ω rd, SOD-123 package (2.7 × 1.6 × 1.1 mm) | Lower ESD rating (16 kV HBM); requires external protection in harsh ESD environments | Choose when cost sensitivity outweighs ESD robustness and thermal headroom is moderate |
Compared with BZX84-C6V2 and MMSZ4687, RKZ6.2BKV delivers superior thermal performance (700 mW), lowest dynamic impedance (50 Ω), and highest ESD immunity (30 kV), making it optimal for space-constrained, high-reliability industrial and automotive voltage reference designs where long-term stability and surge resilience are mandatory.

FAQ
What is the zener voltage tolerance of RKZ6.2BKV?
The RKZ6.2BKV has a zener voltage range of 5.86 V to 6.53 V at 10 mA test current, corresponding to a ±5% tolerance band centered on the nominal 6.2 V rating. This tight specification ensures consistent regulation performance across production lots without requiring binning or calibration in most feedback and reference applications.
Does RKZ6.2BKV support high-temperature operation?
Yes, RKZ6.2BKV is rated for junction temperatures from −55°C to +150°C and storage temperatures up to +150°C. Its thermal derating curve shows usable power dissipation down to 200 mW at 100°C ambient, making it suitable for under-hood automotive modules and enclosed industrial controllers where airflow is limited.
What is the package type and mounting compatibility of RKZ6.2BKV?
RKZ6.2BKV uses the SRP-F (Small Resin Package Flat lead) package, JEITA code PWSF0002ZB-A, with 2.8 mm × 1.6 mm footprint and 0.9 mm height. It is compatible with standard reflow profiles for lead-free soldering and fits automated pick-and-place equipment calibrated for JEDEC MS-012–compatible footprints.
How does RKZ6.2BKV perform under ESD stress?
RKZ6.2BKV achieves ±30 kV human-body-model (HBM) ESD rating per JESD22-A114, verified with 10 pulses in both forward and reverse directions. This exceeds IEC 61000-4-2 Level 4 requirements and eliminates the need for additional TVS diodes in many industrial I/O protection schemes.
Can RKZ6.2BKV replace older Zener diodes like 1N4735A in existing designs?
RKZ6.2BKV is not a direct drop-in replacement for through-hole devices like 1N4735A due to its SRP-F SMT package and different thermal characteristics. However, it can substitute in new SMT designs targeting 6.2 V regulation with improved ESD robustness, lower dynamic resistance, and tighter VZ tolerance - provided PCB layout accommodates the 2.8 × 1.6 mm footprint and thermal pad design rules.
