Product details
Overview
RCLAMP7538P.TZT from Semtech is an 8-line ultra-low-capacitance TVS array designed for ESD protection of high-speed differential interfaces including HDMI 1.4, MHL, LVDS, and eSATA. It delivers ±25kV air/±20kV contact IEC 61000-4-2 ESD immunity, 0.60pF max I/O-to-ground capacitance, and 0.42Ω typical dynamic resistance in a compact 3.8 × 1.0 × 0.50 mm SLP3810N9 package.
For engineers reviewing the RCLAMP7538P.TZT datasheet, pinout, applications, or equivalent options, key selection criteria include clamping voltage at 5A (21V), junction capacitance at 0V (0.60pF), flow-through layout compatibility, and IEC 61000-4-5 lightning surge rating (5A, 8/20μs).
Technical Context
The RCLAMP7538P.TZT integrates eight bidirectional silicon-avalanche TVS diodes in a single monolithic die, each configured as a grounded-cathode rail-to-rail clamp. Its flow-through pin arrangement (I/O–GND–I/O sequence) enables matched trace lengths for differential pairs without vias or stubs.
It operates with a 5V working voltage (VWM), 11.5V breakdown voltage (VBR), and clamps to ≤21V at 5A peak pulse current per line-meeting signal integrity requirements for >3 GHz data rates while suppressing ESD, CDE, and 40A EFT transients.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ESD Rating (IEC 61000-4-2) | ±25kV air, ±20kV contact - ensures robust handling during board assembly and end-user operation |
| Clamping Voltage (IPP = 5A) | 21V max - limits transient overvoltage below IC I/O absolute maximum ratings |
| Junction Capacitance (0V, 1MHz) | 0.60pF max (I/O to GND) - preserves signal integrity on HDMI/MHL/LVDS links up to 3+ GHz |
| Dynamic Resistance | 0.42Ω typ - minimizes voltage overshoot during fast ESD events |
| Lightning Surge (IEC 61000-4-5) | 5A (8/20μs) - protects against induced surges on external cable interfaces |

Applications
| HDMI 1.4 Interfaces | MHL Interfaces |
|---|---|
Use Scenario: Protection of HDMI source/sink ports against ESD during hot-plug and cable handling in TVs, monitors, and AV receivers. IC Role / Device Role / Timing Role: Bidirectional rail-to-rail TVS array placed directly at connector, clamping transients before they reach HDMI transmitter/receiver PHY. Use Value: Maintains <0.6pF loading per lane to preserve TMDS eye diagram integrity at 3.4 Gbps, verified by S21 insertion loss <−1.3 dB @ 2.7 GHz. | Use Scenario: ESD safeguarding of Mobile High-Definition Link (MHL) ports in smartphones and docking stations. IC Role / Device Role / Timing Role: Eight-line protection for MHL's four differential pairs (CLK, D0+, D0−, D1+, D1−, etc.), leveraging flow-through pinout for matched length routing. Use Value: Enables direct placement adjacent to MHL connector with no trace detours-critical for maintaining 75Ω single-ended impedance and minimizing jitter accumulation. |
| LVDS Display Interfaces | eSATA Interfaces |
Use Scenario: Transient suppression on LVDS video buses driving high-resolution panels in automotive instrument clusters and industrial HMIs. IC Role / Device Role / Timing Role: Ground-referenced clamping for LVDS differential pairs, with low capacitance preserving edge rate and reducing bit error rate. Use Value: 0.60pF capacitance prevents rise-time degradation beyond 1 ns, supporting pixel clock frequencies up to 150 MHz with minimal skew between pairs. | Use Scenario: External SATA port protection in NAS enclosures and docking stations exposed to user-handled cables. IC Role / Device Role / Timing Role: Dual-directional surge suppression for eSATA's two differential lanes (TX/RX), rated for IEC 61000-4-5 5A lightning surges. Use Value: Clamps 8/20μs surges to ≤21V within 1 ns, preventing damage to SATA controller PHY while maintaining backward compatibility with SATA II/III signaling. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SP1006-08UTG | 0.5pF max capacitance, 17V clamping at 5A, SOT-143 package (larger footprint, non-flow-through) | Higher pin count density not supported; requires vias for differential routing, increasing parasitic inductance | Preferred where lower clamping voltage is critical and board space permits larger package |
| TPD8E003DRBR | 0.5pF max capacitance, 12V clamping at 5A, 10-pin X2SON package with separate GND pins | Higher channel count (8 lines + dedicated GNDs) but lacks flow-through layout; less optimal for strict impedance-controlled layouts | Chosen when tighter clamping voltage is required and layout allows discrete ground connections per line |
Compared with SP1006-08UTG and TPD8E003DRBR, the RCLAMP7538P.TZT uniquely combines flow-through routing, 0.60pF capacitance, and 21V clamping in a 3.8×1.0mm footprint-making it the preferred choice for space-constrained, high-frequency differential interfaces requiring minimal signal distortion.

FAQ
What is the maximum operating temperature range for RCLAMP7538P.TZT?
The RCLAMP7538P.TZT has a specified operating junction temperature range of −55°C to +125°C, enabling reliable deployment in automotive infotainment systems, industrial displays, and outdoor digital signage where ambient temperatures fluctuate widely. This thermal range is validated under continuous DC bias and transient stress conditions per Semtech's reliability testing protocol.
Does RCLAMP7538P.TZT support differential pair protection without signal degradation?
Yes, the RCLAMP7538P.TZT supports differential pair protection without signal degradation through its flow-through pinout (I/O–GND–I/O), which allows straight PCB trace routing with matched lengths. Measured insertion loss is −0.09 dB at 800 MHz and −1.31 dB at 2.7 GHz, confirming minimal impact on high-speed eye diagrams for HDMI 1.4 and MHL interfaces.
What is the clamping voltage of RCLAMP7538P.TZT at 16A peak pulse current?
The RCLAMP7538P.TZT clamps to 31V maximum at 16A peak pulse current (8/20μs waveform), as confirmed by TLP characterization data in the official datasheet. This value reflects worst-case device behavior under high-energy transients and remains well below the 3.3V/5V I/O absolute maximum ratings of most protected PHYs.
Is RCLAMP7538P.TZT compatible with lead-free reflow soldering processes?
Yes, RCLAMP7538P.TZT is fully compatible with standard lead-free reflow profiles, including JEDEC J-STD-020-compliant peak temperatures up to 260°C. Its NiPdAu lead finish and SLP3810N9 package are qualified for Type 3 solder paste and 60–90 second time-above-liquidus exposure, with recommended stencil aperture dimensions provided in Semtech's assembly guidelines.
How many differential pairs can RCLAMP7538P.TZT protect simultaneously?
The RCLAMP7538P.TZT protects four differential pairs simultaneously-each pair using two I/O pins (e.g., pins 1&2 for first pair, 3&4 for second, etc.) with shared ground terminals. Its 9-pin configuration allocates eight I/O terminals across four balanced channels, making it ideal for HDMI, MHL, and LVDS applications requiring full-lane protection.
