Product details
Overview
GMF05LC-HS3-GS08 from Vishay Semiconductors is a 5-line bidirectional asymmetrical ESD protection diode array in LLP75-6A package, rated for 5 V reverse stand-off voltage (VRWM), 43 pF typical line capacitance at 0 V, and ±30 kV IEC 61000-4-2 contact/air discharge immunity - deployed to safeguard high-speed USB 2.0, HDMI, and SD card interface lines.
For engineers reviewing the GMF05LC-HS3-GS08 datasheet, GMF05LC-HS3-GS08 pinout, GMF05LC-HS3-GS08 application, or GMF05LC-HS3-GS08 equivalent, key selection criteria include clamping voltage under 5 A surge (11.5–12.5 V), low leakage (<0.1 µA), RoHS-compliant lead-free packaging, and BiAs-mode asymmetrical clamping behavior for signal integrity preservation in compact portable electronics.
Technical Context
The GMF05LC-HS3-GS08 implements bidirectional asymmetrical (BiAs) protection: each of five signal lines (pins 1, 3–6) clamps positive transients above 6–8 V breakdown (VBR) to ground (pin 2) with reverse clamping (VC = 11.5–12.5 V @ 5 A), while negative transients are clamped near ground via forward conduction (VF = 3.1–4 V @ 5 A). This enables differential signal path protection without DC bias dependency.
Its LLP75-6A package supports high-density routing with 0.5 mm pitch, MSL Level 1 moisture sensitivity, and UL 94 V-0 molding compound - optimized for reflow-compatible assembly in space-constrained consumer and mobile designs where ESD robustness must coexist with <50 pF capacitance per line.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Protection Lines | 5 independent signal paths - enables single-device protection of full USB 2.0 (D+, D−, ID, VBUS sense, GND-referenced control) |
| VRWM | 5 V - matches standard 3.3 V/5 V logic rail systems without overvoltage risk during normal operation |
| Clamping Voltage (VC) | 11.5–12.5 V @ 5 A (IEC 61000-4-5) - limits transient overshoot below IC absolute maximum ratings |

| ESD Immunity | ±30 kV contact / ±30 kV air (IEC 61000-4-2) - exceeds industrial and automotive ESD test requirements |
| Leakage Current (IR) | ≤0.1 µA @ 5 V - prevents battery drain in always-on portable device interfaces |
| Package | LLP75-6A (1.6 × 1.6 × 0.55 mm) - enables 0.5 mm pitch layout on ultra-thin PCBs |

| Low 43 pF Capacitance @ 0 V | Minimizes insertion loss and timing skew on 480 Mbps USB 2.0 differential pairs without requiring trace length matching compensation |
| ±30 kV ESD Rating | Guarantees survivability through full IEC 61000-4-2 qualification - eliminates need for secondary board-level protection in handheld product enclosures |
| LLP75-6A Ultra-Compact Footprint | Reduces PCB area by >60% vs. SOIC-8 ESD arrays - critical for thin-profile smartphones and wearables with stacked flex-rigid boards |
Applications
| USB 2.0 Interface Protection | HDMI TMDS Channel Protection |
|---|---|
Use Scenario: Protecting D+/D−, ID, VBUS sense, and GND-referenced control lines in smartphone USB OTG ports against repeated electrostatic discharge during cable insertion. IC Role / Device Role / Timing Role: ESD transient suppressor placed directly at connector entry point - operates transparently during 480 Mbps data transmission. Use Value: Prevents latch-up or gate oxide damage in USB PHY ICs by clamping 5 A surges to ≤12.5 V while adding only 43 pF loading per line. | Use Scenario: Safeguarding three TMDS data channels and one clock channel in portable media player HDMI outputs subjected to user-handling ESD. IC Role / Device Role / Timing Role: Asymmetrical clamping device referenced to local ground - maintains differential signal swing integrity across 2.25 Gbps video links. Use Value: Delivers <25 pF capacitance at 2.5 V bias to preserve eye diagram opening, with ±30 kV immunity eliminating field failure returns. |
| SD Card Slot ESD Protection | Mobile Display Serial Interface (DSI) Lane Protection |
Use Scenario: Shielding SDIO bus lines (DAT0–DAT3, CMD, CLK) in tablet memory card slots from ESD events during hot-swap operations. IC Role / Device Role / Timing Role: 5-line protection array covering all six SD card signals except power - placed within 3 mm of connector per JEDEC guidelines. Use Value: Enables compliance with IEC 61000-4-2 Level 4 using single-component solution, reducing BOM count versus discrete diode arrays. | Use Scenario: Protecting four high-speed DSI data lanes and one clock lane in foldable OLED display modules where mechanical flexing increases ESD coupling risk. IC Role / Device Role / Timing Role: Low-capacitance transient voltage suppressor mounted adjacent to display connector - operates in BiAs mode to avoid DC offset on AC-coupled lanes. Use Value: Maintains <50 pF loading per lane to prevent jitter accumulation across 1.5 Gbps/lane DSI streams while surviving repeated 8 kV contact discharges. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NUP4201MR6T1G | 6-line array, 5.5 V VRWM, 30 pF @ 0 V, ±30 kV ESD - but uses SOT-563 package (larger footprint, 2.2 × 1.35 mm) | Supports one additional line; lower capacitance but higher package height (1.1 mm) limits use in ultra-thin devices | Select when needing sixth protected line or tighter capacitance tolerance, accepting larger PCB area |
| Texas Instruments TPD4E001DRYR | 4-line array, 5.5 V VRWM, 12 pF @ 0 V, ±15 kV ESD - LLP-4 package (1.0 × 1.0 mm), lower capacitance but halved ESD rating | Optimized for RF front-end or antenna switch ESD; insufficient for full USB 2.0 or HDMI protection | Choose only for low-capacitance, low-ESD-risk subcircuits - not a functional replacement for GMF05LC-HS3-GS08's 5-line ±30 kV capability |
Compared with NUP4201MR6T1G and TPD4E001DRYR, the GMF05LC-HS3-GS08 uniquely balances 5-line coverage, ±30 kV immunity, and 43 pF capacitance in a 1.6 mm² footprint - making it the only option meeting USB 2.0 + VBUS sense + ID detection protection in minimal space without sacrificing ESD margin.

FAQ
What is the exact pin configuration and signal assignment for GMF05LC-HS3-GS08?
The GMF05LC-HS3-GS08 uses a 6-pin LLP75-6A package with pin 1 (L1), pin 2 (ground), pin 3 (L2), pin 4 (L3), pin 5 (L4), and pin 6 (L5). Each signal line (L1–L5) connects to a separate data or control path, while pin 2 serves as the common ground reference for all five bidirectional protection paths in BiAs mode. This layout is confirmed in Figure 2 of Vishay Document 85655 Rev. 1.7.
Does GMF05LC-HS3-GS08 support unidirectional or bidirectional ESD protection?
The GMF05LC-HS3-GS08 provides bidirectional asymmetrical (BiAs) protection: it clamps positive transients above 6–8 V (VBR) in reverse mode and negative transients near ground via forward conduction (VF = 3.1–4 V @ 5 A). This dual-mode behavior is intrinsic to its internal diode architecture and explicitly defined in the "BiAs-Mode" section of the datasheet.
What is the maximum peak pulse current rating for GMF05LC-HS3-GS08?
The GMF05LC-HS3-GS08 is rated for 5 A peak pulse current (IPPM) per line under IEC 61000-4-5 8/20 µs waveform conditions, with corresponding peak pulse power of 70 W. This value is specified in the Absolute Maximum Ratings table (page 2) and verified in Figure 6 of the datasheet showing VC vs. IPP performance.
Is GMF05LC-HS3-GS08 compatible with lead-free reflow soldering processes?
Yes, GMF05LC-HS3-GS08 is lead (Pb)-free and RoHS-compliant, qualified for lead-free reflow with peak temperature of 260 °C for 10 seconds at terminals. Its LLP75-6A package meets J-STD-020 MSL Level 1, permitting unlimited floor life and compatibility with standard Pb-free reflow profiles used in high-volume electronics assembly.
How does the line capacitance of GMF05LC-HS3-GS08 vary with applied voltage?
The GMF05LC-HS3-GS08 exhibits voltage-dependent capacitance: 43 pF typical at 0 V reverse bias, dropping to 25 pF at 2.5 V reverse bias (measured at 1 MHz). This behavior is documented in the Electrical Characteristics table and illustrated in Figure 3 ("Capacitance vs. Reverse Voltage"), enabling dynamic optimization for high-speed interfaces operating near mid-supply.
