Product details
Overview
RKZ10B2KG#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 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 - deployed in compact consumer electronics power rails and I/O protection networks.
For engineers reviewing the RKZ10B2KG#P1 datasheet, RKZ10B2KG#P1 pinout, RKZ10B2KG#P1 application, or RKZ10B2KG#P1 equivalent, key selection criteria include its URP (SC-76A) ultra-small surface-mount package, ±0.22 V Zener tolerance at 5 mA, ESD robustness to ±30 kV (IEC 61000-4-2), and thermal derating curve supporting operation up to 150°C junction temperature.
Technical Context
This Zener diode operates as a two-terminal voltage reference and transient suppressor, leveraging planar diffusion technology for stable breakdown characteristics. Its design targets precision clamping in low-current analog monitoring paths and overvoltage protection for microcontroller GPIOs and sensor interfaces.
The device exhibits a negative temperature coefficient near 10 V (≈ –0.04 %/°C), confirmed by Renesas' characteristic curves, and supports non-repetitive surge reverse power up to ~1.2 W for 10 ms - validated via reference surge waveform testing per JEDEC standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 9.77–10.21 V at IZ = 5 mA - ensures tight regulation for 10 V reference or clamp applications with ±2.2% initial tolerance. |
| Reverse Leakage (IR) | ≤2 μA at VR = 7.0 V - guarantees minimal standby current draw in battery-powered sensor nodes. |
| Dynamic Resistance (rd) | 30 Ω max at IZ = 5 mA - maintains low impedance for effective noise suppression and stable regulation under load variation. |
| Power Dissipation (Pd) | 200 mW at Ta = 25°C on PCB - enables use in space-constrained PCB layouts without forced cooling. |
| ESD Capability | ±30 kV (HBM, C = 150 pF, R = 330 Ω) - provides robust immunity against handling and system-level electrostatic discharge events. |
| Junction Temperature (Tj) | –55°C to +150°C - supports deployment in industrial ambient environments and thermally dense assemblies. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX55C10 (ON Semiconductor) | Same 10 V nominal Zener, but larger DO-35 glass package (4.5 mm length); 500 mW Pd, higher rd (200 Ω), no halogen-free certification. | Not suitable for high-density SMT; requires axial through-hole layout or adapter; lacks ESD rating documentation. | Select when higher surge energy handling is required and board space permits larger package. |
| MMSZ5240B (Diodes Inc.) | SOD-123 package (1.8 × 1.4 × 1.0 mm); 10 V Zener, 200 mW Pd, rd = 17 Ω, but only rated to ±8 kV HBM ESD. | Compatible footprint width but 64% taller; lower ESD robustness limits use in unshielded external I/O zones. | Prefer for cost-sensitive consumer designs where ESD exposure is controlled and height budget allows. |
Compared with BZX55C10 and MMSZ5240B, RKZ10B2KG#P1 uniquely combines URP's ultra-low profile, industry-leading ±30 kV ESD immunity, and halogen-free compliance - making it optimal for next-gen compact, ruggedized, and environmentally regulated designs.

FAQ
What is the Zener voltage tolerance of RKZ10B2KG#P1 at 5 mA test current?
The RKZ10B2KG#P1 has a specified Zener voltage range of 9.77 V to 10.21 V at IZ = 5 mA, corresponding to a ±2.2% tolerance about the nominal 10.0 V value. This tight tolerance is verified per Renesas' REJ03G1512-0300 datasheet and supports precision regulation in analog front-ends where reference stability is critical. The RKZ10B2KG#P1 achieves this consistency through planar diffusion process control and 100% electrical screening.
Does RKZ10B2KG#P1 support lead-free reflow soldering?
Yes, RKZ10B2KG#P1 is fully compatible with lead-free reflow processes. It is certified halogen-free and Pb-free per JEDEC J-STD-020, with a moisture sensitivity level (MSL) of 1 - meaning it can be stored indefinitely at ambient conditions and withstand peak reflow temperatures up to 260°C without popcorn failure. The RKZ10B2KG#P1's URP package uses thermally stable epoxy resin qualified for standard Pb-free profiles.
What is the maximum allowable reverse voltage before significant leakage in RKZ10B2KG#P1?
Per the datasheet, RKZ10B2KG#P1 guarantees reverse leakage current ≤2 μA at VR = 7.0 V. This defines the practical upper limit for safe non-conducting operation - well below the 10 V Zener threshold. Operating RKZ10B2KG#P1 continuously at ≥7.0 V in reverse bias risks exceeding this spec and may accelerate aging. For reliable clamping, apply only transient surges above 10 V, not sustained DC reverse bias.
How does the ESD rating of RKZ10B2KG#P1 compare to standard Zener diodes?
RKZ10B2KG#P1 is rated for ±30 kV HBM ESD (C = 150 pF, R = 330 Ω), significantly exceeding typical Zener diodes (often ≤8 kV). This rating is achieved via optimized junction geometry and passivation in the URP package, and is validated per IEC 61000-4-2 test methodology. Unlike generic Zeners, RKZ10B2KG#P1 is explicitly characterized for system-level ESD robustness - making it suitable for direct placement on exposed I/O traces without additional TVS stages.
Can RKZ10B2KG#P1 be used as a substitute for a 10 V voltage reference IC in precision circuits?
RKZ10B2KG#P1 serves as a basic 10 V reference but lacks the temperature stability, long-term drift control, and output current capability of dedicated voltage reference ICs (e.g., REF5010). Its temperature coefficient is ≈ –0.04 %/°C, resulting in ~±4 mV/°C drift - acceptable for non-critical biasing but insufficient for 16-bit ADC references. Use RKZ10B2KG#P1 where cost, size, and simplicity outweigh absolute accuracy; for precision metrology, pair it with trimming or select an IC reference.
