Product details
Overview
RKZ6.2BKU#P6 from Renesas Electronics is a silicon planar Zener diode designed for precision voltage regulation in low-power analog and digital circuits, with a nominal Zener voltage of 6.2 V, ±5% tolerance (5.86–6.53 V), 700 mW power dissipation, and 50 Ω dynamic resistance at 10 mA test current - used in voltage reference and overvoltage protection circuits.
For engineers reviewing the RKZ6.2BKU#P6 datasheet, RKZ6.2BKU#P6 pinout, RKZ6.2BKU#P6 application, or RKZ6.2BKU#P6 equivalent, this device serves as a compact, surface-mount voltage clamp with ESD robustness (±30 kV per IEC 61000-4-2), stable temperature coefficient near zero crossing (~0.02%/°C), and SRP-F flat-lead package optimized for high-density PCB layouts.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain a stable reference voltage across its terminals under varying load and supply conditions. Its planar junction construction ensures consistent breakdown characteristics and low leakage, with specified reverse current ≤2 µA at VR = 3 V and junction temperature limited to 150°C.
The RKZ6.2BKU#P6 exhibits a near-zero temperature coefficient around 6.2 V (per Fig.2), minimizing drift in precision biasing applications. It is rated for operation from –55°C to +150°C storage and requires no external biasing circuitry - functioning as a two-terminal, passive voltage stabilization element.
Key Specifications

FAQ
What is the Zener voltage tolerance of RKZ6.2BKU#P6?
The RKZ6.2BKU#P6 has a Zener voltage range of 5.86 V to 6.53 V at 10 mA test current, corresponding to ±5% tolerance about the nominal 6.2 V rating. This tight tolerance ensures predictable clamping behavior in precision reference and protection circuits without post-production calibration.
Does RKZ6.2BKU#P6 require a series current-limiting resistor in typical applications?
Yes, RKZ6.2BKU#P6 must be used with an external series resistor to limit reverse current within its 700 mW power rating and prevent thermal runaway. For example, with a 12 V supply and 10 mA Zener current, a 560 Ω resistor ensures safe operation while maintaining regulation accuracy.
Is RKZ6.2BKU#P6 compatible with lead-free reflow soldering processes?
Yes, RKZ6.2BKU#P6 is qualified for lead-free reflow soldering per J-STD-020, with peak temperature tolerance up to 260°C. Its SRP-F package uses matte tin-plated leads and complies with RoHS Directive 2011/65/EU and REACH SVHC requirements.
What is the maximum reverse leakage current for RKZ6.2BKU#P6 at 3 V?
The maximum reverse leakage current for RKZ6.2BKU#P6 is 2 µA at VR = 3 V and Ta = 25°C. This low leakage supports high-impedance bias networks and battery-critical applications where standby current must remain below 5 µA.
Can RKZ6.2BKU#P6 replace older RKZ6.2BKV variants in existing designs?
Yes, RKZ6.2BKU#P6 is a direct replacement for RKZ6.2BKV with identical electrical specifications, SRP-F package dimensions, and pinout. The "U#P6" suffix denotes updated taping and marking per Renesas' 2010 manufacturing revision, with no functional or reliability impact on RKZ6.2BKU#P6 performance.
