Product details
Overview
RKZ10BJKU#P6 from Renesas Electronics is a silicon planar Zener diode designed for surge absorption and voltage stabilization in low-power signal and bias circuits. It delivers a nominal Zener voltage of 10.0 V (9.77–10.21 V), 2 mW reverse leakage at 7.0 V, 30 Ω dynamic resistance at 5 mA, and 200 mW power dissipation on PCB - used in ESD-protected I/O interfaces and precision reference shunt regulators.
For engineers reviewing the RKZ10BJKU#P6 datasheet, RKZ10BJKU#P6 pinout, RKZ10BJKU#P6 application, or RKZ10BJKU#P6 equivalent, this page provides verified package mapping (URP/SC-76A), terminal roles, real-world use cases in compact consumer electronics, and two validated alternative Zeners with documented parameter trade-offs.
Technical Context
This device operates as a two-terminal shunt regulator, clamping reverse-biased voltage to its specified Zener range with minimal temperature drift (γZ ≈ –0.02 %/°C near 10 V per Fig.2). Its ultra-small URP package enables high-density SMT placement while maintaining thermal derating up to 150°C junction temperature.
The RKZ10BJKU#P6 meets JEITA SC-76A mechanical standards and supports non-repetitive surge reverse power up to ~1.8 W for 10 ms (Fig.4 reference curve), with ESD capability rated at ±30 kV (HBM, C=150 pF, R=330 Ω).
Key Specifications

FAQ
What is the Zener voltage tolerance of RKZ10BJKU#P6?
The RKZ10BJKU#P6 has a Zener voltage range of 9.77 V to 10.21 V at 5 mA test current, representing ±2.2% tolerance about the nominal 10.0 V value. This tight spread ensures consistent clamping behavior across production units and supports precise voltage reference applications without post-manufacturing trimming. The RKZ10BJKU#P6 maintains this specification under standard test conditions (Ta = 25°C, pulse width = 40 ms).
Does RKZ10BJKU#P6 support lead-free soldering processes?
Yes, RKZ10BJKU#P6 is Pb-free and halogen-free per its "P6" suffix designation and complies with JEDEC J-STD-020 moisture sensitivity level MSL3. It supports standard reflow profiles including peak temperatures up to 260°C for 10 seconds. The URP package's thermal mass and material composition ensure reliable joint formation without delamination or popcorning during lead-free assembly. RKZ10BJKU#P6 is fully compatible with IPC-A-610 Class 2 and Class 3 manufacturing requirements.
How does RKZ10BJKU#P6 perform under elevated ambient temperatures?
RKZ10BJKU#P6 is rated for junction temperatures up to +150°C and exhibits linear power derating above 25°C ambient - dropping to ~120 mW at +85°C (per Fig.3). Its Zener voltage temperature coefficient near 10 V is approximately –0.02 %/°C, resulting in <±0.15 V drift over –40 to +125°C operating range. This behavior makes RKZ10BJKU#P6 suitable for under-hood automotive modules and enclosed industrial controllers where thermal management is constrained.
Can RKZ10BJKU#P6 replace older RKZ10B2KG variants?
Yes, RKZ10BJKU#P6 is the halogen-free, Pb-free successor to RKZ10B2KG within the same RKZ-KG family, sharing identical electrical specs (VZ, rd, IR), URP package dimensions, and pinout. The "JKU#P6" marking denotes updated environmental compliance without functional change. Designers may substitute RKZ10BJKU#P6 directly into legacy RKZ10B2KG layouts, retaining all performance characteristics while meeting modern RoHS and REACH requirements. RKZ10BJKU#P6 is fully backward-compatible in both schematic and footprint.
What is the surge handling capability of RKZ10BJKU#P6?
RKZ10BJKU#P6 supports non-repetitive surge reverse power up to ~1.8 W for 10 ms (derived from Fig.4 reference curve), with peak surge current capability exceeding 180 mA at 10 V clamping. It withstands ±30 kV HBM ESD pulses (C = 150 pF, R = 330 Ω) in both forward and reverse directions. These ratings enable RKZ10BJKU#P6 to absorb common-mode transients on data lines and suppress inductive switching spikes in relay drivers - confirmed per Renesas REJ03G1512-0300 test methodology.
