Product details
Overview
RKZ5.6BKV#P1 from Renesas Electronics is a silicon planar Zener diode designed for precision voltage regulation in low-power analog and digital supply rails, featuring a nominal Zener voltage of 5.6 V, ±5% tolerance (5.31–5.92 V), 700 mW power dissipation, 80 Ω dynamic resistance at 10 mA, and ESD capability of 30 kV (HBM). It operates as a shunt voltage reference in compact SMT power management circuits.
For engineers reviewing the RKZ5.6BKV#P1 datasheet, RKZ5.6BKV#P1 pinout, RKZ5.6BKV#P1 application, or RKZ5.6BKV#P1 equivalent, key selection criteria include Zener voltage stability across temperature, low dynamic impedance for ripple suppression, SRP-F surface-mount package compatibility with high-density PCB layouts, and compliance with industrial-grade reliability requirements.
Technical Context
This device uses a planar diffusion process to achieve stable Zener breakdown characteristics with low leakage and predictable temperature coefficient behavior. Its 5.6 V nominal voltage places it near the zero-TC crossing point for silicon Zeners, minimizing drift over –55°C to +150°C ambient range.
The SRP-F flat-lead package enables thermal performance up to 700 mW on standard FR-4 (50 × 50 mm, 1.6 mm thick) with 10 × 10 mm solder land, supporting reliable operation in space-constrained consumer and industrial power supplies without forced cooling.
Key Specifications

| Dynamic Resistance (rd) | 80 Ω max at IZ = 10 mA - provides effective AC ripple rejection in regulated supply feedback paths |
| Power Dissipation (Pd) | 700 mW at Ta = 25°C - supports continuous operation in low-current bias networks without heatsinking |
| ESD Capability | 30 kV HBM (C = 150 pF, R = 330 Ω) - withstands handling and board-level electrostatic events without degradation |
| Junction Temperature (Tj) | 150°C max - enables use in thermally demanding environments including enclosed industrial enclosures |
| Reverse Current (IR) | 5 µA max at VR = 2.5 V - ensures minimal quiescent current draw in battery-backed or ultra-low-power circuits |

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-C5V6 | Same 5.6 V nominal, but SOT-23 package (larger footprint), 400 mW Pd, 40 Ω rd | Higher power density required; less suitable for ultra-compact layouts | Select when lower dynamic resistance is prioritized over board area and higher ESD immunity is not needed |
| MMSZ5232BS | 5.6 V nominal, SOD-123 package, 500 mW Pd, 100 Ω rd, 30 kV HBM | Similar ESD rating but higher rd degrades ripple rejection in sensitive analog rails | Select when cost sensitivity outweighs need for lowest possible impedance in precision references |

FAQ
What is the Zener voltage tolerance of RKZ5.6BKV#P1?
The RKZ5.6BKV#P1 has a Zener voltage range of 5.31 V to 5.92 V at 10 mA test current, corresponding to ±5% tolerance around the nominal 5.6 V rating. This specification is guaranteed per the REJ03G1700-0100 datasheet and applies under standard 25°C ambient conditions with pulse testing (Pw = 40 ms).
Does RKZ5.6BKV#P1 support high-temperature operation?
Yes, RKZ5.6BKV#P1 is rated for junction temperatures up to 150°C and storage temperatures from –55°C to +150°C. Its planar silicon construction and SRP-F package enable stable regulation across this full industrial temperature range, provided PCB thermal design meets the specified 50 × 50 mm glass-epoxy board requirement.
What is the maximum reverse current for RKZ5.6BKV#P1 at 2.5 V?
The maximum reverse current (IR) for RKZ5.6BKV#P1 is 5 µA when tested at VR = 2.5 V, as specified in the Electrical Characteristics table of the REJ03G1700-0100 datasheet. This low leakage supports ultra-low-power applications such as battery-backed sensors and sleep-mode reference circuits.
Is RKZ5.6BKV#P1 compatible with lead-free reflow processes?
Yes, RKZ5.6BKV#P1 is qualified for lead-free reflow soldering per J-STD-020. The SRP-F package and internal construction meet RoHS requirements and withstand peak reflow temperatures up to 260°C, ensuring compatibility with standard Type 3 and Type 4 solder pastes used in high-volume SMT manufacturing.
How does the dynamic resistance of RKZ5.6BKV#P1 affect its regulation performance?
The dynamic resistance of RKZ5.6BKV#P1 is 80 Ω maximum at 10 mA, directly determining how much output voltage shifts under changing load current. Lower rd yields tighter regulation - for example, a 1 mA load change causes only ~80 mV deviation, making RKZ5.6BKV#P1 suitable for precision bias and feedback applications where stability matters.
