Product details
Overview
RKZ15BKV#P1 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 14.7 V (min 13.84 V, max 15.52 V), dynamic resistance of 40 Ω at 5 mA, power dissipation rating of 700 mW, and ESD capability of ±30 kV per IEC 61000-4-2. It operates within –55°C to +150°C junction temperature range and is used in compact DC-DC converter reference stages.
For engineers reviewing the RKZ15BKV#P1 datasheet, RKZ15BKV#P1 pinout, RKZ15BKV#P1 application, or RKZ15BKV#P1 equivalent, this device serves as a surface-mount voltage reference with tight tolerance (±5% VZ), low dynamic impedance, and high ESD robustness - critical for stable regulation in space-constrained industrial sensor interfaces and microcontroller supply monitoring.
Technical Context
The RKZ15BKV#P1 implements a silicon planar Zener structure optimized for stable reverse-breakdown operation under controlled current conditions. Its 40 Ω dynamic resistance at 5 mA ensures minimal output voltage variation across load changes, while its 700 mW power rating enables use in non-heatsinked applications up to 70°C ambient when mounted on standard FR-4 PCBs.
Designed for constant-voltage regulation, it features a cathode-anode terminal configuration in a flat-lead SRP-F package, with ESD protection rated to ±30 kV (C = 150 pF, R = 330 Ω) in both forward and reverse directions - supporting reliable operation in electrostatic-prone assembly environments and end-use industrial settings.
Key Specifications

FAQ
What is the Zener voltage tolerance of RKZ15BKV#P1?
The RKZ15BKV#P1 has a Zener voltage range of 13.84 V to 15.52 V at IZ = 5 mA, corresponding to ±5% tolerance around the nominal 14.7 V value. This is confirmed in the Electrical Characteristics table on page 2 of the REJ03G1700-0100 datasheet. The RKZ15BKV#P1 maintains this tolerance across its operating temperature range without derating.
Does RKZ15BKV#P1 support surface-mount assembly?
Yes, RKZ15BKV#P1 uses the SRP-F (Small Resin Package Flat lead) package with gull-wing terminals, explicitly designed for reflow soldering on PCBs. Its dimensions (1.6 mm × 2.8 mm) and tape-and-reel packaging (3,000 pcs/reel) are optimized for high-speed pick-and-place machines, as documented in the Ordering Information and Package Dimensions sections of the datasheet.
What is the maximum reverse current specification for RKZ15BKV#P1?
The RKZ15BKV#P1 specifies a maximum reverse current (IR) of 2 µA at VR = 11 V, per the Electrical Characteristics table. This low leakage ensures minimal error in high-impedance voltage divider or bias networks. The value is measured under standardized test conditions and applies across the full storage temperature range (–55°C to +150°C).
How does the ESD rating of RKZ15BKV#P1 compare to standard Zener diodes?
RKZ15BKV#P1 is rated for ±30 kV ESD per IEC 61000-4-2 (C = 150 pF, R = 330 Ω) in both forward and reverse directions - significantly exceeding typical unqualified Zeners. This eliminates the need for external ESD protection in many applications. The RKZ15BKV#P1 achieves this via process-level design enhancements detailed in Renesas' preliminary characterization report REJ03G1700-0100.
Can RKZ15BKV#P1 replace TL431 in shunt regulator applications?
RKZ15BKV#P1 can serve as a passive shunt reference in place of TL431 where active regulation and adjustable output are not required. Unlike TL431, RKZ15BKV#P1 has no internal amplifier or feedback pins - it provides fixed 14.7 V regulation with 40 Ω dynamic resistance. Use RKZ15BKV#P1 when simplicity, lower cost, and zero quiescent current are priorities over programmability or tighter initial accuracy.
