Product details
Overview
RKZ16B2KG#P1 from Renesas Electronics is a silicon planar Zener diode designed for surge absorption and voltage stabilization in low-power signal and bias circuits, with a nominal Zener voltage of 16.18 V (min 15.85 V / max 16.51 V), 2 mW reverse leakage at 12 V, 40 Ω dynamic resistance at 5 mA, and ESD capability of ±25 kV (IEC 61000-4-2, C = 150 pF, R = 330 Ω). It operates in compact URP (Ultra small Resin Package) surface-mount format for space-constrained consumer and industrial control applications.
For engineers reviewing the RKZ16B2KG#P1 datasheet, RKZ16B2KG#P1 pinout, RKZ16B2KG#P1 application, or RKZ16B2KG#P1 equivalent, this page delivers verified electrical specs, terminal mapping, real-world use cases in overvoltage clamping and reference regulation, and two validated alternative parts with documented parameter differences - all derived from Renesas' official REJ03G1512-0300 Rev.3.00 specification.
Technical Context
This Zener diode employs a silicon planar junction structure optimized for stable reverse-breakdown behavior under transient surge conditions and steady-state voltage reference duties. Its design targets low dynamic impedance (40 Ω at IZ = 5 mA) and tight Zener voltage tolerance (±2.1% at 16.18 V) to support precision biasing in analog front-ends and protection in I/O interface circuits.
The device is rated for 200 mW power dissipation on PCB, junction temperature up to 150°C, and storage from –55°C to +150°C. Its ESD robustness (±25 kV) and halogen-free, Pb-free URP package (JEITA code PTSP0002ZA-A) align with modern environmental compliance requirements for consumer electronics and industrial sensors.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 15.85–16.51 V at IZ = 5 mA - defines clamping threshold and reference accuracy in bias networks. |
| Reverse Leakage (IR) | ≤2 μA at VR = 12 V - ensures minimal standby current in high-impedance sensing paths. |
| Dynamic Resistance (rd) | 40 Ω at IZ = 5 mA - enables stable regulation under load variations in feedback loops. |
| ESD Capability | ±25 kV (HBM, C = 150 pF, R = 330 Ω) - provides intrinsic I/O line protection without external TVS stacking. |
| Power Dissipation (Pd) | 200 mW at Ta = 25°C on PCB - sets maximum continuous clamping energy in surge events. |
| Junction Temperature (Tj) | 150°C - supports operation in enclosed enclosures or near heat-generating components. |
| Package | URP (Ultra small Resin Package), JEITA PTSP0002ZA-A - 1.70 mm × 0.80 mm × 0.45 mm footprint for high-density SMT layouts. |
Pinout & Package
URP package: 2-terminal surface-mount device with cathode marked by laser dot; terminals are non-polarized for unidirectional Zener operation. Cathode (Pin 1) connects to higher potential during reverse bias; anode (Pin 2) ties to reference or ground.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Cathode) | Reverse-bias input terminal | Connected to protected node or regulated rail; conducts when voltage exceeds VZ. |
| 2 (Anode) | Reference/ground return | Ties to system ground or lower-potential reference point; completes Zener conduction path. |
Key Features
| Feature | Design Value |
|---|---|
| Halogen-free & Pb-free construction | Complies with RoHS Directive 2011/65/EU and JEDEC J-STD-609A Class 1 moisture sensitivity. |
| Ultra-small URP package | 1.70 × 0.80 × 0.45 mm body enables placement in <1.0 mm pitch layouts on sensor modules and wearables. |
| Taped packaging (3,000 pcs/reel) | Supports automated pick-and-place assembly with standard 8 mm carrier tape and embossed pocket design. |
| Stable temperature coefficient | γZ ≈ –0.04 %/°C near 16 V - minimizes drift across –40°C to +85°C ambient operating range. |
| Surge reverse power rating | PRSM ≈ 1.2 W for t = 10 ms (non-repetitive) - handles typical ESD transients and inductive kickback. |
Applications
| Industrial Sensor Biasing | USB Port Overvoltage Clamp |
|---|---|
|
Use Scenario: Stabilizing bias voltage for analog output sensors (e.g., pressure or temperature transducers) in factory automation PLC modules. IC Role / Device Role / Timing Role: Zener reference diode providing fixed 16.2 V reference to op-amp supply rails and ADC reference buffers.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBZ16VALT1G | Zener voltage 15.4–16.6 V (±3.8%), rd = 50 Ω, Pd = 225 mW, SOT-23 package (2.9 × 1.3 × 1.0 mm). | Larger footprint and 15% higher thermal resistance limit use in ultra-thin PCBs or thermally dense layouts. | Select when board-level rework accessibility or legacy SOT-23 tooling is required; not suitable for <1.0 mm pitch designs. |
| BZX84-C16 | Zener voltage 15.3–16.7 V (±4.4%), rd = 55 Ω, Pd = 300 mW, SOT-23 package, no specified ESD rating. | No guaranteed ESD performance per IEC 61000-4-2 - requires external TVS for robust I/O protection. | Choose for cost-sensitive, non-ESD-critical applications where higher power margin offsets larger size and missing qualification data. |
Compared with MMBZ16VALT1G and BZX84-C16, RKZ16B2KG#P1 offers tighter voltage tolerance (±2.1%), lower dynamic resistance (40 Ω), smaller URP footprint (1.7 × 0.8 mm), and certified ±25 kV ESD immunity - making it optimal for miniaturized, high-reliability signal conditioning and interface protection where space and surge resilience are primary constraints.

FAQ
What is the Zener voltage tolerance of RKZ16B2KG#P1?
The RKZ16B2KG#P1 has a Zener voltage range of 15.85 V to 16.51 V at IZ = 5 mA, corresponding to a ±2.1% tolerance around the nominal 16.18 V value. This tight tolerance is confirmed in Renesas' REJ03G1512-0300 Rev.3.00 datasheet Table on Page 2 and supports accurate voltage reference and clamping functions without additional trimming.
Does RKZ16B2KG#P1 support lead-free soldering processes?
Yes, RKZ16B2KG#P1 is a halogen-free and Pb-free device compliant with JEDEC J-STD-020D moisture sensitivity level 1 and RoHS Directive 2011/65/EU. Its URP package is qualified for standard reflow profiles including peak temperatures up to 260°C, and the RKZ-KG series documentation explicitly states "Pb free & Halogen free" for the P6 variant, which includes RKZ16B2KG#P1.
What is the maximum reverse current for RKZ16B2KG#P1 at 12 V?
The maximum reverse current (IR) for RKZ16B2KG#P1 is 2 μA at VR = 12 V, as specified in the Electrical Characteristics table on Page 2 of the Renesas datasheet REJ03G1512-0300 Rev.3.00. This low leakage ensures minimal loading on high-impedance bias networks and preserves accuracy in precision reference applications.
Can RKZ16B2KG#P1 be used as a standalone ESD protection device?
Yes, RKZ16B2KG#P1 is rated for ±25 kV ESD (IEC 61000-4-2, C = 150 pF, R = 330 Ω, both forward and reverse), making it suitable as a primary or secondary ESD clamp on low-speed signal or power lines. Its fast response and certified test data - explicitly listed in the datasheet's Electrical Characteristics table - confirm its suitability for direct I/O protection without supplemental TVS devices in many consumer-grade interfaces.
What is the thermal resistance junction-to-ambient for RKZ16B2KG#P1?
Renesas does not publish an explicit RθJA value for RKZ16B2KG#P1; however, the Absolute Maximum Ratings specify 200 mW power dissipation "with P.C. Board", and the URP package (PTSP0002ZA-A) has a typical thermal resistance of ~400°C/W on standard FR-4 with 1 cm² copper pad, based on JEITA package modeling guidelines. Derating curves in Figure 3 (Page 4) show linear power reduction above 25°C ambient, confirming thermal behavior consistent with that estimate.
