Product details
Overview
RKZ7.5Z4MFAKT from Renesas Electronics is a silicon planar Zener diode array in VSON-5 package, integrating four monolithic Zener elements for surge absorption on signal lines. It delivers 7.5 V nominal Zener voltage at 5 mA, 4.0 pF typical capacitance, and 8 kV ESD protection (IEC 61000-4-2) in both forward and reverse directions - deployed in high-speed USB and HDMI interface protection.
For engineers reviewing the RKZ7.5Z4MFAKT datasheet, RKZ7.5Z4MFAKT pinout, RKZ7.5Z4MFAKT application, or RKZ7.5Z4MFAKT equivalent, key selection criteria include per-device Zener voltage tolerance (±0.3 V), low dynamic resistance (≤60 Ω), surge power capability (PRSM up to 10 W at 1 ms), and VSON-5 footprint compatibility with high-density PCB layouts.
Technical Context
The RKZ7.5Z4MFAKT implements a quad-cathode / single-anode configuration (pins 1–2–5 = cathode, pin 4 = anode, pin 3 = cathode), enabling parallel clamping of four independent signal paths using one shared anode connection. Its low 4.0 pF capacitance ensures minimal signal integrity impact on data lines operating up to 500 MHz.
Designed for transient suppression, it meets IEC 61000-4-2 Level 4 (±8 kV contact, ±15 kV air) with failure defined as IR > 3 µA at VR = 6.5 V. Each Zener element is rated for 150 mW total power dissipation at 25°C ambient, derating linearly to zero at 150°C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 7.5 V nominal at 5 mA; tight 7.2–7.8 V min/max range ensures precise clamping threshold for 3.3 V and 5 V logic interfaces. |
| Capacitance (C) | 4.0 pF typ at 0 V, 1 MHz; preserves signal rise/fall times in USB 2.0 and LVDS applications without added jitter. |
| ESD Rating | 8 kV contact discharge (IEC 61000-4-2); protects downstream PHYs and controllers from human-body-model transients. |
| Dynamic Resistance (rd) | ≤60 Ω at 5 mA; maintains stable clamping voltage under fast-rising surges (<1 ns edge). |
| Reverse Current (IR) | ≤3 µA at VR = 6.5 V; guarantees low standby leakage in battery-powered sensor nodes and portable devices. |

Applications
| USB 2.0 Data Line Protection | HDMI TMDS Channel Clamp |
|---|---|
Use Scenario: Protecting D+ and D− lines in portable USB hosts and peripherals against ESD events during hot-plug insertion. IC Role / Device Role / Timing Role: Bidirectional transient voltage suppressor placed directly at connector, clamping surges before reaching USB transceiver. Use Value: 4.0 pF capacitance prevents signal degradation beyond USB 2.0 eye mask limits; quad layout matches D+/D− pair + ID/VBUS sense routing. | Use Scenario: Clamping TMDS clock and data channels in HDMI source devices (e.g., set-top boxes, GPUs) exposed to handling ESD. IC Role / Device Role / Timing Role: Low-capacitance Zener clamp on each of three TMDS differential pairs and clock line. Use Value: Simultaneous protection of four high-speed channels with single VSON-5 footprint reduces BOM count and layout complexity vs. discrete diodes. |
| Industrial RS-485 Transceiver Guard | Automotive Infotainment Display Interface |
Use Scenario: Surge suppression on A/B bus lines of RS-485 transceivers in factory automation gateways subjected to 2 kV ring wave transients. IC Role / Device Role / Timing Role: Front-end TVS element absorbing energy prior to transceiver input stage. Use Value: 8 kV ESD rating and 10 W PRSM withstand capability meet IEC 61000-4-4 Level 3 requirements without external series impedance. | Use Scenario: Protecting MIPI D-PHY lanes between infotainment head unit and LCD display module in automotive cabins. IC Role / Device Role / Timing Role: Signal-line Zener clamp placed at display connector to prevent latch-up in display driver ICs. Use Value: VSON-5 package fits constrained space behind dashboard bezels; 7.5 V VZ aligns with 5 V supply rail clamping margin for 3.3 V logic interfaces. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener-based surge suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NSQA4060MR6T5G | Single-channel 6.0 V Zener; 3.5 pF capacitance; SOT-563 package (1.6 × 1.6 mm). | Requires four separate placements for quad-channel use; higher board area (4× vs. 1× VSON-5). | Select when lower capacitance (3.5 pF) is critical and layout allows discrete placement. |
| TPD4E001DPYR | Quad-channel ESD array; 5.5 V working voltage; 0.9 pF per channel; 5-pin X2SON. | Lower clamping voltage (5.5 V) limits use to 3.3 V systems; not a Zener - uses silicon avalanche structure. | Select for ultra-high-speed interfaces (>1 Gbps) where sub-1 pF capacitance outweighs Zener precision. |
Compared with NSQA4060MR6T5G and TPD4E001DPYR, the RKZ7.5Z4MFAKT provides tighter 7.5 V Zener regulation and integrated quad layout in smallest footprint, making it optimal for space-constrained 5 V interface protection where precise clamping voltage and surge energy handling are prioritized over minimum capacitance.

FAQ
What is the Zener voltage tolerance of RKZ7.5Z4MFAKT at 5 mA test current?
The RKZ7.5Z4MFAKT has a specified Zener voltage range of 7.2 V (min) to 7.8 V (max) at IZ = 5 mA, corresponding to ±0.3 V absolute deviation from the 7.5 V nominal value. This tight tolerance ensures consistent clamping behavior across production lots and supports reliable interface-level surge protection in 5 V systems where overvoltage margins are constrained.
Does RKZ7.5Z4MFAKT support bidirectional ESD protection?
Yes, RKZ7.5Z4MFAKT provides bidirectional ESD protection with 8 kV contact discharge capability in both forward and reverse directions per IEC 61000-4-2. This is achieved via its symmetric Zener structure between cathode and anode terminals, enabling effective clamping regardless of transient polarity on protected signal lines.
What is the maximum non-repetitive surge power (PRSM) rating for RKZ7.5Z4MFAKT?
The RKZ7.5Z4MFAKT supports up to 10 W of non-repetitive surge reverse power (PRSM) at a 1 ms pulse width, as defined in Figure 3 of its datasheet. This rating applies per individual Zener element within the quad array and is valid only for single-event, non-repetitive transients - continuous power dissipation remains limited to 150 mW at 25°C ambient.
Is RKZ7.5Z4MFAKT compatible with reflow soldering per JEDEC J-STD-020?
Yes, RKZ7.5Z4MFAKT is qualified for standard Pb-free reflow soldering per JEDEC J-STD-020D, with peak temperature up to 260°C for ≤30 seconds. Its VSON-5 package (PUSN0005KB-A) has MSL Level 1 rating, meaning it may be stored indefinitely at ≤30°C/60% RH without dry-pack requirements prior to assembly.
How does the pin configuration of RKZ7.5Z4MFAKT support four-channel protection?
RKZ7.5Z4MFAKT uses a 5-pin VSON-5 layout with pins 1, 2, 3, and 5 assigned as independent cathodes (one per Zener element) and pin 4 as the common anode. This allows four separate signal lines to be clamped to a shared reference (ground or bias rail), minimizing inter-channel coupling and simplifying PCB routing compared to discrete solutions.
