Product details
Overview
UCLAMP2424PWQ.C from Semtech is a transient voltage suppression (TVS) diode array designed for ESD and surge protection of high-speed data lines including USB 2.0, HDMI, and DisplayPort interfaces. It features a 24 V working voltage, 30 A peak pulse current (8/20 µs), ±15 kV IEC 61000-4-2 contact ESD rating, and a compact SOT-563 (SC-88) package with six terminals.
For engineers reviewing the UCLAMP2424PWQ.C datasheet, pinout, applications, or equivalent options, key selection criteria include clamping voltage at rated current, channel count, bidirectional protection capability, low capacitance per line, and automotive-grade AEC-Q101 qualification status.
Technical Context
The UCLAMP2424PWQ.C integrates four bidirectional TVS diodes in a single monolithic silicon avalanche structure, enabling simultaneous protection of four high-speed signal pairs without signal degradation. Its low dynamic resistance ensures fast response to transients while maintaining sub-0.8 pF capacitance per channel - critical for preserving signal integrity above 1 GHz.
Designed for automotive infotainment and ADAS subsystems, it operates across –40 °C to +125 °C ambient and meets ISO 10605 (330 pF/330 Ω) and IEC 61000-4-5 (4 A, 8/20 µs) surge immunity standards. The device uses a rail-to-rail clamping architecture with no DC bias dependency.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SP1006-04UTG | Lower working voltage (12 V), higher capacitance (1.2 pF), same SOT-563 package and AEC-Q101 rating. | Better suited for 12 V systems (e.g., CAN FD data lines) but unsuitable for 24 V industrial buses due to premature conduction. | Select UCLAMP2424PWQ.C when protecting 24 V-rated interfaces where clamping margin and low capacitance are critical. |
| SMAJ24A-Q | Discrete DO-214AC package, unidirectional, 200 W peak power, 55 V clamping at 5.5 A - not quad-channel or low-capacitance. | Used for bulk power rail protection, not high-speed data lines; requires four separate devices and PCB area >10× larger. | Choose UCLAMP2424PWQ.C for space-constrained, multi-line signal protection where layout density and signal fidelity matter. |
Compared with SP1006-04UTG and SMAJ24A-Q, the UCLAMP2424PWQ.C uniquely combines 24 V operation, quad-channel integration, sub-0.8 pF capacitance, and AEC-Q101 qualification - making it the only option for compact, high-fidelity ESD protection of 24 V-rated high-speed serial interfaces in automotive and industrial settings.

FAQ
What is the maximum clamping voltage of UCLAMP2424PWQ.C at 30 A (8/20 µs)?
The UCLAMP2424PWQ.C has a maximum clamping voltage of 42 V when subjected to a 30 A 8/20 µs surge current. This value is measured per channel with the cathode terminal grounded and anode driven by the surge waveform. The clamping voltage remains consistent across all four channels due to monolithic construction, ensuring uniform protection for differential signal pairs in the UCLAMP2424PWQ.C.
Is UCLAMP2424PWQ.C qualified for automotive applications?
Yes, UCLAMP2424PWQ.C is AEC-Q101 qualified for automotive use. It has passed stress tests including temperature cycling, highly accelerated life testing (HALT), and ESD validation per JESD22-A114. Its operating temperature range of –40 °C to +125 °C ambient and robust surge immunity make it suitable for deployment in automotive infotainment, ADAS camera modules, and display interfaces where UCLAMP2424PWQ.C is specified.
How many protected channels does UCLAMP2424PWQ.C provide?
UCLAMP2424PWQ.C provides four independent bidirectional ESD protection channels in a single SOT-563 package. Each channel consists of a matched anode–cathode pair, sharing a common cathode terminal (Pin 2). This quad-channel architecture allows simultaneous protection of two differential pairs - such as USB 2.0 D+/D− and ID lines - without cross-talk or performance degradation in the UCLAMP2424PWQ.C.
What is the typical capacitance per channel for UCLAMP2424PWQ.C?
The typical capacitance per channel of UCLAMP2424PWQ.C is 0.75 pF at 1 MHz and 0 V bias. Measured differentially between anode and cathode pins, this low value ensures minimal impact on signal rise/fall times and insertion loss in high-speed serial links. Designers rely on this specification to maintain signal integrity in applications like HDMI 2.1 and USB 3.2 Gen 2x1 where UCLAMP2424PWQ.C is deployed.
Does UCLAMP2424PWQ.C require external biasing or control signals?
No, UCLAMP2424PWQ.C is a passive TVS diode array requiring no external biasing, power supply, or control signals. It operates solely through avalanche breakdown of its internal silicon junctions during overvoltage events. Its rail-to-rail clamping behavior functions identically for positive and negative transients, simplifying design integration in AC-coupled interfaces where UCLAMP2424PWQ.C is applied.
