Product details
Overview
RKZ6.2Z4MFAKT from Renesas Electronics is a silicon planar Zener diode array in VSON-5 package, integrating four monolithic Zener devices for coordinated surge absorption on signal lines. It delivers 6.2 V nominal Zener voltage (5.90–6.50 V at 5 mA), 4.0 pF typical capacitance, and 8 kV ESD protection per IEC 61000-4-2 (150 pF/330 Ω). It is used in high-density USB, HDMI, and LVDS interface protection circuits.
For engineers reviewing the RKZ6.2Z4MFAKT datasheet, RKZ6.2Z4MFAKT pinout, RKZ6.2Z4MFAKT application, or RKZ6.2Z4MFAKT equivalent, key selection criteria include its quad-cathode topology, low 4.0 pF capacitance for high-speed signal integrity, 150 mW total power dissipation, and verified 8 kV ESD robustness in both forward and reverse directions.
Technical Context
This device implements four independent Zener clamping cells in a single VSON-5 die, sharing no internal interconnects-each cathode is electrically isolated except for common thermal coupling. Its 6.2 V Zener voltage targets logic-level rail clamping (e.g., 5 V or 3.3 V systems), with dynamic resistance ≤60 Ω ensuring fast transient response under 5 mA test current.
The 4.0 pF capacitance is measured at 0 V bias and 1 MHz, enabling use on signal lines up to ~1 GHz without significant insertion loss. ESD failure threshold is defined as IR > 3 µA at VR = 5.5 V after 10 pulses, confirming stable post-surge leakage performance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage | 5.90–6.50 V at 5 mA: Clamps transients above 5.9 V while staying below 6.5 V to avoid overstressing downstream 5 V-tolerant receivers. |
| Capacitance | 4.0 pF typ at 0 V, 1 MHz: Enables placement on high-speed differential pairs (e.g., USB 2.0, HDMI) without degrading signal rise time or eye diagram. |
| ESD Rating | 8 kV contact discharge (IEC 61000-4-2): Protects interfaces against human-body-model surges without requiring external series impedance. |
| Power Dissipation | 150 mW total (four devices): Supports simultaneous clamping of multiple signal lines within thermal limits of VSON-5 package. |
| Reverse Current | ≤3 µA at VR = 5.5 V: Ensures minimal DC loading on protected signal lines during normal operation. |
| Dynamic Resistance | ≤60 Ω at IZ = 5 mA: Provides low-impedance clamping path for fast-rising transients (<1 ns edge). |
Pinout & Package
VSON-5 surface-mount package (JEITA code PUSN0005KB-A), 1.6 mm × 1.3 mm × 0.6 mm body, 0.5 mm pitch, wettable flank terminals for automated optical inspection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode | Clamping node for first Zener cell; connects to protected signal line via PCB trace. |
| 2 | Cathode | Clamping node for second Zener cell; electrically isolated from Pin 1 for multi-line protection. |
| 3 | Cathode | Clamping node for third Zener cell; enables independent routing to separate I/O lines. |
| 4 | Anode | Common anode tied to system ground or reference rail; shared by all four Zener cells. |
| 5 | Cathode | Clamping node for fourth Zener cell; completes quad-channel ESD protection capability. |
Key Features
| Feature | Design Value |
|---|---|
| Quad-monolithic Zener architecture | Four independent 6.2 V clamping cells in one die reduce board area vs. discrete diodes and ensure matched thermal behavior. |
| Low 4.0 pF capacitance | Preserves signal integrity on high-speed interfaces (e.g., USB 2.0 full-speed, MIPI D-PHY) without added series resistance or equalization. |
| VSON-5 high-density packaging | 0.5 mm pitch and 1.6 × 1.3 mm footprint supports miniaturized portable electronics and dense FPGA I/O banks. |
| 8 kV bidirectional ESD protection | Validated for both forward and reverse polarity surges, eliminating need for external polarity-aware layout. |
Applications
| USB 2.0 Interface Protection | HDMI Signal Line Clamp |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener-based surge absorption applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPD4E001DRYR | Quad 5.5 V TVS with 0.5 pF capacitance; uses silicon avalanche structure instead of Zener; lower clamping voltage (7.5 V @ 1 A). | Better for ultra-high-speed (>5 Gbps) interfaces due to lower capacitance; less suitable for precise 6.2 V rail clamping. | Select when signal bandwidth exceeds 5 GHz and clamping voltage margin is secondary to capacitance. |
| SZ1.5SMC6.8AT3G | Single-channel 6.8 V Zener TVS in SMC package; 1500 W peak power; 100 pF capacitance; through-hole or large SMT footprint. | Designed for bulk power-line surge suppression-not signal-line ESD; incompatible with high-density layouts. | Choose only for low-frequency power rail protection where board space and speed are not constraints. |
Compared with TPD4E001DRYR and SZ1.5SMC6.8AT3G, RKZ6.2Z4MFAKT uniquely balances 6.2 V precision clamping, 4.0 pF signal-line compatibility, and quad-channel integration in a 1.6 × 1.3 mm footprint-making it optimal for space-constrained, high-speed digital interface protection where voltage accuracy and layout density are critical.

FAQ
What is the Zener voltage tolerance of RKZ6.2Z4MFAKT?
The RKZ6.2Z4MFAKT has a specified Zener voltage range of 5.90 V to 6.50 V at 5 mA test current, with no guaranteed typical value-designers must accommodate this ±0.3 V window when setting clamping margins relative to downstream IC absolute maximum ratings. This tolerance reflects process variation across the monolithic quad die and is confirmed per device in the Electrical Characteristics table.
Can RKZ6.2Z4MFAKT be used for bidirectional signal line protection?
Yes, RKZ6.2Z4MFAKT provides verified 8 kV ESD protection in both forward and reverse directions per IEC 61000-4-2 (150 pF/330 Ω), with failure defined as reverse leakage exceeding 3 µA at 5.5 V after 10 pulses. Its symmetrical Zener breakdown behavior enables direct placement on bidirectional buses like I²C or SMBus without polarity concerns.
How does the VSON-5 package of RKZ6.2Z4MFAKT support automated optical inspection (AOI)?
The RKZ6.2Z4MFAKT's VSON-5 package features wettable flank terminals-vertical sidewalls with solderable metallization-that reflect light consistently during AOI. This enables reliable detection of solder joint quality (e.g., head-in-pillow, insufficient fill) without requiring X-ray, supporting high-yield manufacturing of compact consumer electronics assemblies.
Is RKZ6.2Z4MFAKT rated for continuous DC operation at its Zener voltage?
No-RKZ6.2Z4MFAKT is designed for transient suppression, not steady-state regulation. Its absolute maximum power dissipation is 150 mW total (all four devices), limiting continuous DC current to ~24 mA at 6.2 V. For DC bias applications, a dedicated regulator or higher-power Zener should be used; RKZ6.2Z4MFAKT operates only during surge events.
What is the thermal derating behavior of RKZ6.2Z4MFAKT above 25°C ambient?
RKZ6.2Z4MFAKT's power dissipation derates linearly above 25°C ambient: Fig.2 shows 150 mW at 25°C dropping to zero at 150°C junction temperature. The thermal resistance θJA is approximately 833°C/W, meaning each 1°C rise above 25°C reduces allowable power by ~1.26 mW-critical for designs operating near 85°C ambient with repeated surge exposure.
