Product details
Overview
RCLAMP7534F.TCT from Semtech is a low-capacitance TVS diode array designed to protect four high-speed LVDS data lines against ESD (±15kV air, ±8kV contact), EFT (40A), and CDE transients. It features 3.9pF typical junction capacitance per I/O line, 5.0V operating voltage, clamping voltage ≤30V at 10A (2/10μs), and SC-70-6 package with matte tin lead finish.
For engineers reviewing the RCLAMP7534F.TCT datasheet, pinout, applications, or equivalent options, key selection criteria include sub-4pF capacitance for 2.0GHz signal integrity, IEC 61000-4-2 Level 4 compliance, and validated protection of LVDS interfaces in LCD TV and display timing systems.
Technical Context
The RCLAMP7534F.TCT integrates four surge-rated steering diodes and one shared TVS diode in a single SC-70-6 package, enabling bidirectional transient shunting from any I/O pin (1, 3, 4, 6) to ground (pin 2). Its silicon-avalanche architecture delivers non-repetitive peak pulse power up to 300W at 25°C.
It operates at 5.0V working voltage with 9.5V minimum breakdown voltage and 30V maximum clamping voltage at 10A, supporting high-speed interfaces without insertion loss up to 2.0GHz. Pin 2 is dedicated ground; no internal connection exists between I/O pins.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 5.0V - Matches standard LVDS supply rails; ensures stable operation without false triggering. |
| Junction Capacitance | 3.9pF @ 0V - Enables minimal signal distortion on >1Gbps differential links (e.g., LVDS, FPD-Link). |
| ESD Rating | ±15kV air / ±8kV contact (IEC 61000-4-2 Level 4) - Meets industrial and consumer display immunity requirements. |
| Clamping Voltage | ≤30V @ 10A (2/10μs) - Limits voltage seen by downstream LVDS receiver ICs during surge events. |
| Package | SC-70-6 (2.0 × 1.25 × 1.1 mm) - Ultra-compact footprint ideal for space-constrained display interface PCB layouts. |
| Leakage Current | ≤0.3μA @ 5V - Prevents DC loading of high-impedance LVDS termination networks. |
Pinout & Package
SC-70-6 package with EIAJ-compliant outline; nominal dimensions 2.0 × 1.25 × 1.1 mm; matte tin lead finish; RoHS/WEEE compliant; marking "F75".
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | I/O Line 1 | Protected high-speed data line (e.g., LVDS+); connects to upstream trace before protected IC. |
| 2 | Ground | Dedicated low-inductance ground return path; must connect directly to solid ground plane. |
| 3 | I/O Line 2 | Protected high-speed data line (e.g., LVDS−); electrically isolated from other I/O pins. |
| 4 | I/O Line 3 | Third protected line; supports multi-channel LVDS or FPD-Link interfaces. |

Applications
| LCD TV Timing Interface | LVDS Display Module Protection |
|---|---|
Use Scenario: Protecting LVDS clock and data lanes between mainboard SoC and large-panel LCD TV display driver ICs. IC Role / Device Role: Transient voltage suppressor placed inline on all four LVDS differential traces (CLK+, CLK−, DATA+, DATA−). Use Value: Maintains <3pF loading per line to prevent jitter accumulation and eye diagram closure at 1080p/60Hz timing rates. | Use Scenario: Safeguarding embedded display modules in industrial HMIs where cable discharge events are frequent. IC Role / Device Role: ESD clamp on FPD-Link III or OpenLDI interface lines connecting controller to panel. Use Value: Withstands repeated ±8kV contact discharges without parameter shift, ensuring long-term reliability in factory environments. |
| Notebook Display Flex Cable Interface | Medical Imaging Monitor Data Link |
Use Scenario: Shielding high-speed video data paths routed across thin flex cables prone to triboelectric charging. IC Role / Device Role: Localized TVS at flex-to-PCB transition point to minimize inductance in ESD current path. Use Value: Sub-2mm SC-70 footprint allows placement within 3mm of connector, reducing parasitic loop area by >60% vs. SOIC alternatives. | Use Scenario: Protecting diagnostic-grade video transmission in DICOM-compliant medical monitors requiring zero packet loss. IC Role / Device Role: Final-stage transient guard before high-precision LVDS receiver ASICs handling 4K grayscale imaging data. Use Value: Clamping voltage ≤30V prevents latch-up in sensitive analog front-end circuitry during hospital-grade ESD testing. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar TVS diode array applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SP1003-04UTG | Higher capacitance (5.5pF), lower clamping voltage (24V @ 10A), SOT-23-6 package (2.9 × 1.6 × 1.1 mm) | Better suited for USB 2.0 or HDMI DDC lines where bandwidth <480MHz; less optimal for >1Gbps LVDS. | Select SP1003-04UTG only if board layout allows larger footprint and system tolerates +1.6pF per line. |
| TPD4E001DPVR | Lower working voltage (3.3V), identical 3.5pF capacitance, same SC-70-6 package, but rated only to ±12kV ESD. | Targeted at 3.3V logic domains (e.g., MIPI D-PHY); insufficient for 5V-tolerant LVDS receivers requiring Level 4 immunity. | Choose TPD4E001DPVR only when interfacing with 3.3V I/O buffers and ESD requirement is ≤±12kV. |
Compared with SP1003-04UTG and TPD4E001DPVR, the RCLAMP7534F.TCT uniquely balances 5.0V operation, ±15kV ESD rating, and sub-4pF capacitance in the smallest SC-70-6 form factor-making it the only option qualified for next-gen 1080p/4K display timing interfaces demanding both size and performance.

FAQ
What is the maximum clamping voltage of the RCLAMP7534F.TCT under a 10A ESD pulse?
The RCLAMP7534F.TCT has a maximum clamping voltage of 30V when subjected to a 10A (2/10μs) peak pulse current, as specified in its Absolute Maximum Ratings table. This value ensures downstream LVDS receivers remain within safe operating voltage limits during transient events. The RCLAMP7534F.TCT achieves this via integrated avalanche TVS and steering diode architecture optimized for low-voltage, high-speed lines.
Can the RCLAMP7534F.TCT protect more than four signal lines simultaneously?
No-the RCLAMP7534F.TCT is configured to protect exactly four I/O lines (pins 1, 3, 4, and 6), each referenced to the dedicated ground pin (pin 2). There is no internal connectivity between I/O pins, and the device does not support protection of additional lines beyond these four. For eight-line protection, two RCLAMP7534F.TCT units are required.
Does the RCLAMP7534F.TCT require external components for basic ESD protection?
No external components are required for baseline ESD protection; the RCLAMP7534F.TCT functions as a standalone TVS array. However, an optional 10Ω series resistor per line (as shown in Semtech's Application Information diagram) can further limit ESD current into the protected IC and improve robustness-especially in high-risk cable-discharge scenarios. The RCLAMP7534F.TCT itself contains no internal resistors.
Is the RCLAMP7534F.TCT compatible with lead-free reflow soldering processes?
Yes-the RCLAMP7534F.TCT uses matte tin lead finish and complies with IPC-J-STD-020 moisture sensitivity level (MSL) 1, supporting standard lead-free reflow profiles up to 260°C peak temperature. Its UL 94V-0 molding compound and SC-70 package are fully qualified for Pb-free manufacturing. The RCLAMP7534F.TCT datasheet confirms compatibility with JEDEC-standard reflow cycles.
What is the leakage current specification for the RCLAMP7534F.TCT at its rated working voltage?
The RCLAMP7534F.TCT exhibits a maximum leakage current of 0.3μA at 5.0V reverse working voltage and 25°C ambient temperature, as stated in its Electrical Characteristics table. This ultra-low leakage prevents DC loading of high-impedance LVDS termination networks and avoids signal degradation in precision timing applications. The RCLAMP7534F.TCT maintains this spec across its full operating temperature range (−40°C to +125°C).
