Product details
Overview
RKZ3.6B2KG#P6 from Renesas Electronics is a silicon planar Zener diode designed for surge absorption and voltage stabilization in low-power signal conditioning and protection circuits, with a nominal Zener voltage of 3.6 V (3.55–3.80 V), 10 μA maximum reverse current at 1.0 V, 130 Ω typical dynamic resistance at 5 mA, and 200 mW power dissipation on PCB - deployed in compact consumer sensor interfaces and USB port ESD clamping.
For engineers reviewing the RKZ3.6B2KG#P6 datasheet, RKZ3.6B2KG#P6 pinout, RKZ3.6B2KG#P6 application, or RKZ3.6B2KG#P6 equivalent, this device serves as a halogen-free, Pb-free surface-mount Zener for precision low-voltage regulation and transient suppression where thermal derating above 25°C and ESD robustness (±30 kV per IEC 61000-4-2) are critical selection criteria.
Technical Context
This Zener operates in reverse-biased breakdown mode to maintain stable reference voltage under varying load and temperature conditions. Its ultra-small URP (SC-76A) package enables high-density mounting, and its halogen-free construction complies with JEDEC J-STD-020 moisture sensitivity level 1 requirements.
The device exhibits a negative temperature coefficient near 3.6 V (≈ –0.04 %/°C), confirmed by Fig.2 in REJ03G1512-0300, and supports nonrepetitive surge reverse power up to ~1.2 W for 10 ms (Fig.4), making it suitable for transient overvoltage clamping in low-energy signal paths.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX584-C3V6 | Same nominal VZ (3.6 V), but SOD-323 package (1.7 × 1.3 mm); 250 mW Pd; ±5% tolerance | Higher power margin but larger footprint; less suitable for ultra-dense layouts | Select BZX584-C3V6 only if board space allows 0.4 mm wider body and higher thermal mass is needed |
| MMSZ4685 | VZ = 3.68 V (3.5–3.85 V), SOD-123 package (3.7 × 1.6 mm); 500 mW Pd; no halogen-free guarantee | Higher surge capability but incompatible with lead-free/halogen-free compliance mandates | Choose MMSZ4685 only for non-regulated industrial designs requiring >200 mW continuous dissipation |

FAQ
What is the Zener voltage tolerance of RKZ3.6B2KG#P6 at 5 mA?
The RKZ3.6B2KG#P6 has a Zener voltage range of 3.55 V to 3.80 V at 5 mA test current, corresponding to ±3.5% tolerance about the nominal 3.6 V value. This tight tolerance is specified in the Electrical Characteristics table on page 2 of REJ03G1512-0300 and enables precise voltage clamping without additional trimming components in RKZ3.6B2KG#P6-based designs.
Does RKZ3.6B2KG#P6 meet RoHS and halogen-free requirements?
Yes, RKZ3.6B2KG#P6 is explicitly designated as a halogen-free and Pb-free part (RKZ-KG-P6 Series), compliant with EU RoHS Directive 2011/65/EU. The "P6" suffix confirms full conformance, and the device carries no brominated flame retardants or chlorine-based compounds - verified in the Features section and Ordering Information table of REJ03G1512-0300 for RKZ3.6B2KG#P6.
What is the maximum allowable ambient temperature for RKZ3.6B2KG#P6 at full 200 mW power dissipation?
RKZ3.6B2KG#P6 achieves its full 200 mW rated power dissipation only at Ta = 25°C. As shown in Fig.3 (Power Dissipation vs. Ambient Temperature), derating begins linearly above 25°C, reaching zero dissipation at approximately 150°C. For continuous operation at 200 mW, ambient temperature must remain at or below 25°C - a key thermal constraint in RKZ3.6B2KG#P6 layout planning.
How is the cathode identified on the RKZ3.6B2KG#P6 package?
The cathode of RKZ3.6B2KG#P6 is marked with a visible band on terminal 1, consistent with the Pin Arrangement diagram on page 1 of REJ03G1512-0300. The laser mark "3 • 6" appears adjacent to this band, confirming orientation. Correct polarity is essential: cathode connects to the protected signal line, anode to ground - misorientation renders RKZ3.6B2KG#P6 ineffective for reverse-transient clamping.
What ESD test standard does the 30 kV rating for RKZ3.6B2KG#P6 follow?
The ±30 kV ESD capability of RKZ3.6B2KG#P6 is measured per Human Body Model (HBM) per JEDEC JS-001, using C = 150 pF and R = 330 Ω, with 10 pulses applied in both forward and reverse directions. This specification is documented in the Electrical Characteristics table (page 2) and Notes section of REJ03G1512-0300 - confirming RKZ3.6B2KG#P6's suitability for direct I/O line protection without supplemental ESD components.
