Product details
Overview
RKZ15B2KG#P1 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 14.66 V (min 14.34 V, max 14.98 V) at 5 mA, with dynamic resistance of 40 Ω, reverse current ≤2 μA at 11.0 V, and 200 mW power dissipation on PCB - used in ESD-protected I/O interfaces and precision reference nodes.
For engineers reviewing the RKZ15B2KG#P1 datasheet, RKZ15B2KG#P1 pinout, RKZ15B2KG#P1 application, or RKZ15B2KG#P1 equivalent, key selection criteria include its 14.66 V stabilization point, 25 kV ESD capability (IEC 61000-4-2), ultra-small URP package (SC-76A), and suitability for compact DC biasing, overvoltage clamping, and low-current reference generation in space-constrained consumer and industrial electronics.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain stable voltage under varying load and temperature conditions. Its temperature coefficient is approximately –0.04 %/°C (–5.8 mV/°C) near 15 V, enabling predictable drift compensation in reference designs.
The device uses a silicon planar junction structure with halogen-free, Pb-free resin encapsulation (URP package), rated for junction temperatures up to 150°C and storage from –55°C to +150°C. It supports non-repetitive surge reverse power up to ~1.2 W for 10 ms (per Fig.4 reference curve).

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode voltage stabilization applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBZ15VA (ON Semiconductor) | Zener voltage 14.3–15.8 V (±5%), 350 mW Pd, SOT-23 package (2.9 × 1.3 × 1.0 mm) | Larger footprint; higher power allows higher current bias but reduces board density | Select when higher surge energy handling or legacy SOT-23 layout compatibility is required |
| BZX84-C15 (Nexperia) | Zener voltage 14.3–15.7 V (±5%), 300 mW Pd, SOT-23; no specified HBM rating | No published ESD rating; requires external protection for I/O-facing use cases | Prefer for cost-sensitive, non-exposed internal bias rails where ESD immunity is not critical |
Compared with MMBZ15VA and BZX84-C15, RKZ15B2KG#P1 offers superior board-area efficiency (URP vs. SOT-23), guaranteed ±25 kV HBM rating, and tighter voltage tolerance - making it optimal for miniaturized, ESD-critical applications where space and reliability are prioritized over raw power headroom.

FAQ
What is the Zener voltage tolerance of RKZ15B2KG#P1?
The RKZ15B2KG#P1 has a Zener voltage range of 14.34 V to 14.98 V at 5 mA test current, corresponding to a ±2.2% tolerance about the nominal 14.66 V value. This tight specification ensures predictable clamping and reference behavior without post-manufacturing calibration, and is verified per Renesas REJ03G1512-0300 Rev.3.00 test conditions.
Does RKZ15B2KG#P1 support lead-free soldering processes?
Yes, RKZ15B2KG#P1 is Pb-free and halogen-free, compliant with RoHS Directive 2011/65/EU. Its URP package is qualified for standard reflow profiles including JEDEC J-STD-020 Level 3 (MSL3), with peak temperature up to 260°C. The device's resin molding compound and termination plating are fully compatible with lead-free assembly.
What is the maximum reverse current specification for RKZ15B2KG#P1?
RKZ15B2KG#P1 specifies a maximum reverse current (IR) of 2 μA at VR = 11.0 V, measured at Ta = 25°C. This low leakage supports high-impedance bias networks and minimizes quiescent power loss in battery-operated systems - a key parameter confirmed in the Electrical Characteristics table on page 2 of the Renesas datasheet REJ03G1512-0300.
Can RKZ15B2KG#P1 be used as a standalone ESD protection device?
Yes, RKZ15B2KG#P1 is rated for ±25 kV HBM ESD (C = 150 pF, R = 330 Ω), making it suitable as a primary or secondary ESD clamp on low-speed signal lines such as I²C, UART, or reset inputs. Its 14.66 V breakdown voltage provides safe margin above 3.3 V or 5 V logic rails while limiting clamping voltage to <20 V during transients - validated in Renesas' ESD test methodology (Note 2, page 2).
What is the thermal resistance junction-to-ambient for RKZ15B2KG#P1?
RKZ15B2KG#P1 does not specify an explicit RθJA value in its datasheet; instead, its power derating is defined by the "Power Dissipation vs. Ambient Temperature" curve (Fig.3). At Ta = 25°C, Pd = 200 mW; this drops linearly to zero at Ta = 150°C. For design purposes, assume effective RθJA ≈ 625 K/W based on ΔT = 125°C rise at full Pd, consistent with typical URP-package thermal performance on standard FR-4 PCB.
