Product details
Overview
RKZ16BJKU#P6 from Renesas Electronics is a silicon planar Zener diode optimized for surge absorption and voltage stabilization in compact surface-mount applications. 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 low-power voltage reference and transient protection circuits for microcontroller I/O rails and sensor interfaces.
For engineers reviewing the RKZ16BJKU#P6 datasheet, RKZ16BJKU#P6 pinout, RKZ16BJKU#P6 application, or RKZ16BJKU#P6 equivalent, key selection criteria include its 16.2 V Zener voltage tolerance, 40 Ω dynamic impedance, URP (SC-76A) ultra-small package, 25 kV ESD rating, and halogen-free/Pb-free compliance - critical for space-constrained industrial and consumer electronics requiring robust overvoltage clamping.
Technical Context
This device operates as a two-terminal, reverse-biased voltage reference and clamp. Its Zener breakdown mechanism provides stable regulation under DC bias and fast response to transient surges up to 1 W (non-repetitive, 10 ms pulse), with junction temperature limited to 150°C and storage range from –55°C to +150°C.
The RKZ16BJKU#P6 exhibits a negative temperature coefficient near 0.04 %/°C (≈6.5 mV/°C) at 16.2 V, enabling predictable drift compensation in precision references. Its ultra-small URP package (1.70 mm × 0.80 mm × 0.45 mm) supports high-density PCB layouts while maintaining thermal derating per Fig.3 - Pd drops linearly to ~120 mW at 85°C ambient.
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-C16 (Nexperia) | Same 16 V nominal Zener, but SOD-523 package (1.3 × 0.8 mm); rd = 45 Ω; Pd = 300 mW; ESD = ±30 kV | Larger power handling but 0.4 mm longer footprint; less suitable for ultra-dense layouts where URP's 1.7 mm length is critical | Select when higher surge energy absorption is prioritized over minimal board area |
| MMSZ4687T1G (onsemi) | 16 V Zener in SOD-123FL; rd = 50 Ω; Pd = 500 mW; ESD = ±16 kV; not halogen-free certified | Higher thermal mass improves long-duration transient handling but lacks RKZ16BJKU#P6's 25 kV ESD rating and RoHS-compliant marking | Choose for cost-sensitive industrial designs where ESD immunity is secondary to power derating margin |
Compared with BZX584-C16 and MMSZ4687T1G, RKZ16BJKU#P6 offers the smallest footprint among 16 V Zeners with certified 25 kV ESD and halogen-free compliance - making it optimal for space- and reliability-critical portable and medical-adjacent electronics where layout density and regulatory alignment are primary constraints.

FAQ
What is the Zener voltage tolerance of RKZ16BJKU#P6?
The RKZ16BJKU#P6 has a Zener voltage range of 15.85 V to 16.51 V at 5 mA test current, representing a ±2.1% tolerance around the nominal 16.2 V value. This tight specification ensures consistent clamping behavior across production lots and supports accurate voltage reference design without additional trimming components in RKZ16BJKU#P6-based circuits.
Does RKZ16BJKU#P6 support automated optical inspection (AOI) after placement?
Yes, RKZ16BJKU#P6 features a laser-marked cathode dot visible under standard AOI systems, and its URP package geometry (1.70 × 0.80 mm) meets IPC-A-610 Class 2 fiducial requirements. The flat top surface and defined terminal positions enable reliable solder-joint inspection and coplanarity verification in high-volume RKZ16BJKU#P6 assembly lines.
Can RKZ16BJKU#P6 be used in place of a 15 V Zener diode?
No - RKZ16BJKU#P6 is specified exclusively for 16.2 V nominal regulation and must not substitute for 15 V Zeners due to its guaranteed minimum Zener voltage of 15.85 V. Using RKZ16BJKU#P6 where 15 V clamping is required risks overvoltage damage to downstream circuitry; always verify voltage thresholds against the exact RKZ16BJKU#P6 datasheet parameters before substitution.
What is the thermal resistance junction-to-ambient (RθJA) for RKZ16BJKU#P6?
Renesas does not publish a discrete RθJA value for RKZ16BJKU#P6; instead, derating is defined empirically in Fig.3 of the datasheet: power dissipation declines linearly from 200 mW at 25°C ambient to approximately 120 mW at 85°C. This curve reflects actual board-level thermal performance on a standard polyimide PCB, making RKZ16BJKU#P6 suitable for thermally constrained applications without heatsinking.
Is RKZ16BJKU#P6 qualified for automotive applications?
No - RKZ16BJKU#P6 is rated for Standard-grade applications per Renesas quality classification and is intended for consumer, industrial, and office equipment. It is not AEC-Q200 qualified, lacks automotive-specific qualification testing (e.g., extended temperature cycling, board flex), and should not be deployed in vehicle ECUs or ADAS systems where RKZ16BJKU#P6's 150°C max junction temperature does not meet automotive thermal safety margins.
