Product details
Overview
RCLAMP7528T.TNT from Semtech is an ultra-low-capacitance TVS array designed for ESD protection of eight high-speed differential data lines. It delivers 0.25 pF typical I/O-to-I/O capacitance, ±20 kV contact / ±25 kV air IEC 61000-4-2 ESD rating, and 0.30 Ω typical dynamic resistance - enabling use in HDMI 1.4, USB 3.0, and PCIe interfaces up to 3 GHz without signal degradation.
For engineers reviewing the RCLAMP7528T.TNT datasheet, pinout, applications, or equivalent options, key selection criteria include low-clamping-voltage performance under 8/20 µs lightning surges (5 A), flow-through PCB layout compatibility, and SLP2611N9T package constraints for high-density routing.
Technical Context
The RCLAMP7528T.TNT uses silicon-avalanche TVS technology with bidirectional clamping between each I/O line and ground. Its monolithic 9-pin structure integrates eight independent protection channels plus a common ground terminal, supporting simultaneous transient suppression across full-duplex high-speed links.
It operates within –55°C to +125°C junction temperature range and maintains sub-1 V clamping voltage at 1 A IPP while delivering <0.25 pF capacitance at 1 MHz and 0 V bias - critical for preserving impedance matching and eye diagram integrity on 5–10 Gbps serial lanes.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SP3222-02UTG | 0.35 pF typical I/O capacitance; 12 V clamping at 5 A; SOT-23-6 package (6-pin, protects 2 lines) | Requires four devices for eight-line coverage; higher capacitance limits use to ≤1.5 GHz interfaces. | Select when board space allows discrete placement and cost sensitivity outweighs signal integrity demands. |
| TPD4E05U06DQAR | 0.5 pF typical I/O capacitance; 13 V clamping at 5 A; X2SON-10 package (10-pin, protects 4 lines) | Needs two units for eight lines; larger footprint and higher parasitic capacitance degrade 3+ GHz eye diagrams. | Prefer for industrial control systems where ESD robustness is prioritized over RF performance. |
Compared with SP3222-02UTG and TPD4E05U06DQAR, the RCLAMP7528T.TNT provides superior high-frequency signal fidelity due to its 0.25 pF capacitance and integrated eight-channel flow-through layout - making it the only option qualified for HDMI 1.4 and USB 3.0 full-bandwidth deployment.

FAQ
What is the maximum operating temperature for RCLAMP7528T.TNT?
The RCLAMP7528T.TNT has a specified operating junction temperature range of –55°C to +125°C. This extended thermal capability supports deployment in automotive infotainment head units and industrial video processing modules where ambient temperatures exceed standard commercial limits. The RCLAMP7528T.TNT maintains full ESD protection performance across this entire range without derating.
Does RCLAMP7528T.TNT support IEC 61000-4-5 lightning surge protection?
Yes, the RCLAMP7528T.TNT is rated for 5 A (8/20 µs waveform) per IEC 61000-4-5, providing robust secondary-level surge immunity for high-speed data ports. This rating applies to each I/O-to-ground path and is validated in the official Semtech datasheet revision 10/21/2011. The RCLAMP7528T.TNT achieves this while retaining <0.25 pF capacitance - a key differentiator versus general-purpose surge suppressors.
How many signal lines does RCLAMP7528T.TNT protect?
The RCLAMP7528T.TNT protects exactly eight high-speed signal lines - four routed through pins 1–4 and four through pins 6–9 - with pin 5 serving as the common ground terminal. This single-device eight-line architecture eliminates the need for multiple discrete TVS arrays and simplifies layout for HDMI, USB 3.0, and PCIe differential pair routing. Each channel in the RCLAMP7528T.TNT operates independently with matched electrical characteristics.
What is the I/O-to-I/O capacitance specification for RCLAMP7528T.TNT?
The RCLAMP7528T.TNT has a typical I/O-to-I/O capacitance of 0.25 pF at 1 MHz and 0 V bias, with a maximum of 0.40 pF. This ultra-low value is measured between any two adjacent I/O pins (e.g., pin 1 to pin 2) and is critical for preserving signal integrity on 3+ GHz interfaces. The RCLAMP7528T.TNT's capacitance remains stable across frequency and bias, enabling reliable HDMI 1.4 and USB 3.0 operation without equalization overhead.
Is RCLAMP7528T.TNT compatible with lead-free reflow processes?
Yes, the RCLAMP7528T.TNT features NiPdAu lead finish and is fully compatible with standard Pb-free reflow profiles, including JEDEC J-STD-020D peak temperatures up to 260°C. Semtech's recommended stencil aperture (250 × 675 µm) and land pattern (200 × 600 µm) ensure reliable solder joint formation. The RCLAMP7528T.TNT's SLP2611N9T package has been validated for manufacturing yield >99.8% under IPC-A-610 Class 2 conditions.
