Product details
Overview
RKZ16TKG#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 16.2 V (min 15.85 V, max 16.51 V) at 5 mA, with dynamic resistance of 40 Ω, 200 mW power dissipation, and ESD capability of ±25 kV (IEC 61000-4-2, C = 150 pF, R = 330 Ω). It is used in overvoltage protection for sensor interfaces and reference voltage clamping in industrial control modules.
For engineers reviewing the RKZ16TKG#P1 datasheet, RKZ16TKG#P1 pinout, RKZ16TKG#P1 application, or RKZ16TKG#P1 equivalent, key selection criteria include its 16.2 V Zener tolerance (±2.1%), ultra-small URP package (SC-76A), 25 kV ESD rating, 12.0 V test voltage for reverse current limit, and suitability for compact, high-density PCB layouts requiring halogen-free, Pb-free compliance.
Technical Context
This Zener diode operates as a two-terminal voltage reference and transient suppressor, leveraging silicon planar junction technology for stable breakdown characteristics. Its design targets low-current regulation (IZ = 5 mA) and fast response to ESD events, with thermal derating defined up to 150°C junction temperature.
The device exhibits a negative temperature coefficient near 16 V (≈ –0.04 %/°C per Fig.2), enabling predictable drift behavior in ambient ranges from –55°C to +150°C. Its non-repetitive surge reverse power rating supports transient suppression in short-duration overvoltage events, as shown in Fig.4 reference curves.
Key Specifications
| Parameter | Value and Actual Design Meaning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C16LT1G (ON Semiconductor) | Same 16 V nominal Zener, but SOT-23 package (2.9 × 1.3 × 1.0 mm); 300 mW Pd; 40 Ω rd; ±30 kV ESD | Larger footprint and higher power rating - better for higher-energy surges but less suitable for ultra-dense layouts | Select when board space allows larger package and higher surge margin is required |
| MMSZ4687T1G (ON Semiconductor) | 16 V Zener in SOD-123 (3.7 × 1.6 × 1.1 mm); 500 mW Pd; 50 Ω rd; no published ESD rating | Higher power handling but no specified ESD immunity - requires external ESD protection in harsh environments | Select for cost-sensitive, non-ESD-critical applications where thermal margin is prioritized over miniaturization |
Compared with BZX84-C16LT1G and MMSZ4687T1G, RKZ16TKG#P1 offers the smallest footprint (URP), guaranteed ±25 kV ESD rating, and tighter voltage tolerance (±2.1%), making it optimal for space-constrained, high-reliability industrial I/O designs where both size and robustness are critical.

FAQ
What is the Zener voltage tolerance of RKZ16TKG#P1?
The RKZ16TKG#P1 has a Zener voltage range of 15.85 V to 16.51 V at 5 mA test current, corresponding to a ±2.1% tolerance around the nominal 16.2 V value. This tight tolerance is confirmed in the Electrical Characteristics table on page 2 of the REJ03G1512-0300 datasheet and ensures consistent clamping performance across production lots without calibration.
Does RKZ16TKG#P1 meet RoHS and halogen-free requirements?
Yes, RKZ16TKG#P1 is part of the RKZ-KG P6 Series, explicitly designated as halogen-free and Pb-free per the ordering information on page 1 of REJ03G1512-0300. It complies with JEITA EG-701 and EU RoHS Directive 2011/65/EU, and carries the "P" taping abbreviation indicating environmental compliance.
What is the maximum reverse current specification for RKZ16TKG#P1?
The maximum reverse current (IR) for RKZ16TKG#P1 is 2 μA at a reverse voltage (VR) of 12.0 V, as specified in the Electrical Characteristics table. This low leakage supports high-impedance circuit nodes such as sensor bias networks and reference dividers where current draw must be minimized.
Can RKZ16TKG#P1 replace standard 16 V Zener diodes in existing designs?
RKZ16TKG#P1 can serve as a drop-in replacement for other 16 V Zeners in space-constrained layouts due to its URP (SC-76A) package, but layout verification is required: pad dimensions differ from SOD-323 or SOT-23. Its 200 mW power rating and ±25 kV ESD rating exceed many legacy parts, offering enhanced robustness without changing schematic topology.
What is the thermal derating behavior of RKZ16TKG#P1 above 25°C ambient?
RKZ16TKG#P1 follows the derating curve in Figure 3 (page 4 of REJ03G1512-0300): power dissipation linearly decreases from 200 mW at 25°C to zero at 150°C junction temperature. At 70°C ambient, usable Pd drops to approximately 130 mW - a critical consideration for sealed enclosures or high-density PCBs with limited airflow.
