As serial links such as USB 3.2 Gen2×2, DisplayPort 2.1 and 16 Gbps SerDes push single-ended data rates beyond 20 Gb/s, any ESD device whose capacitance exceeds 0.3 pF behaves like a hidden inductor that slows edges. Slkor’s unidirectional TVS diode SLPESDMC2FD5VB combines a typical junction capacitance of 0.25 pF with a 13 V clamping level, 5 V reverse working voltage (VRWM) and 6 V minimum breakdown voltage (VBR) to deliver virtually “zero-added-load” electrostatic protection on 5 V high-speed single-ended or differential lines, while its reverse leakage is only 100 nA—helping mobile and wearable devices squeeze out even longer standby times.

Mission: intercept ESD, CDE or EFT pulses nanoseconds before they reach the IC I/O and shunt their energy to the ground plane, acting as an “invisible fuse” between the high-speed system and the hostile outside world. Traditional solutions trade higher power handling for larger capacitance, collapsing eye diagrams; SLPESDMC2FD5VB balances 88 W peak pulse power (8/20 µs) with 0.25 pF of capacitance via Slkor’s proprietary deep-well process, making it the ideal silent guardian for smartphones, tablets, notebooks, automotive cameras and AR/VR headsets.

A precisely-tuned protection window
Reverse working voltage VRWM = 5 V
Minimum reverse breakdown VBR = 6 V
This window guarantees that normal 5 V signals are never disturbed, yet the device still clamps reliably under ±15 kV air and ±8 kV contact discharges (IEC 61000-4-2 Level 4) and 40 A, 5/50 ns EFT bursts, fully covering the electrical specs of USB-C SuperSpeed, DisplayPort AUX, PCIe sideband and other 5 V interfaces.

13 V low clamping voltage
At 1 A, 8/20 µs the typical clamp VC is 13 V; at 4 A it rises only to 22 V—well below the 20 V+ transient rating of 5 V CMOS processes, minimizing over-shoot stress and preventing latent gate-oxide damage.

0.25 pF junction capacitance—30 % lower than mainstream offerings
CJ = 0.25 pF typ (@ VR = 0 V, f = 1 MHz, max 0.4 pF)

Insertion loss < –0.15 dB and return loss < –25 dB at 20 GHz keep single-ended edges sharp and eyes wide open above 10 Gbps.

100 nA ultra-low leakage
IR = 100 nA typ (@ VR = 5 V, 25 °C) and remains below 500 nA at 85 °C, adding precious minutes of battery life to phones, TWS earbuds and wearables that must stay on 24/7.

DFN1006 ultra-thin package
Measuring only 1.0 mm × 0.6 mm × 0.5 mm, it occupies 60 % less PCB real estate than SOT-23; the 0.5 mm height slips easily under a USB-C tongue. A centrally-exposed die paddle creates the shortest possible ground path, cutting loop inductance and accelerating ESD discharge. Ni/Pd/Au terminations are lead-free-reflow compatible, and 7-inch tape-and-reel holds 10 kpcs for high-speed pick-and-place lines.

Typical applications
• Mobile: USB-C SuperSpeed lines, headphone jacks, SIM trays, side keys, camera MIPI D-PHY/CSI-2
• Computing: Thunderbolt™ 4/5 lanes on ultra-slim notebooks, HDMI 2.1 ports, SSD M.2 slots
• Automotive: camera FPD-Link III, GMSL links, IVI USB hubs, tuner GPIOs
• Industrial & medical: high-speed DAQ cards, machine-vision cameras, portable ultrasound probe ports
• AR/VR & wearables: AR-glass Micro-OLED links, smart-watch combo charge/data ports

Design Tips
Place the SLPESDMC2FD5VB within 2 mm of the connector ingress. Keep single-ended or differential traces symmetrical and impedance-controlled. Open a solid ground plane window directly beneath the TVS exposed pad—do not share a long ground return path.

In addition, Slkor’s website (www.slkoric.com) offers a wide range of other product families, giving designers even more options.

With its 0.25 pF ultra-low capacitance, 13 V precise clamp, tight 5 V/6 V protection window and 100 nA leakage, SLPESDMC2FD5VB sets a new “invisible” ESD benchmark for 5 V high-speed single-ended and differential interfaces, offering silent yet rock-solid protection for lighter, faster and more reliable end products.
