Product details
Overview
UCLAMP2482PWQ.C from Semtech is a bidirectional 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, 15 kV ESD contact rating per IEC 61000-4-2, low clamping voltage of 48 V at 1 A, and a compact SOT-563 (SC-88) package with six terminals.
For engineers reviewing the UCLAMP2482PWQ.C datasheet, pinout, applications, or equivalent options, key selection considerations include its low capacitance (0.8 pF typical per line), fast response time (<1 ns), bidirectional protection architecture, and AEC-Q200 qualification for automotive-grade reliability.
Technical Context
The UCLAMP2482PWQ.C integrates six independent TVS diodes in a single monolithic silicon structure, configured as three differential pairs for full-line protection. Its low leakage current (<1 µA at 24 V) ensures minimal signal integrity impact on high-speed serial links.
Designed specifically for automotive infotainment and ADAS interfaces, it meets ISO 10605 (330 pF/330 Ω) surge immunity up to ±15 kV and supports operating junction temperatures from –40 °C to +125 °C - exceeding standard industrial requirements.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar TVS diode array applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SP1003-02WTG | Higher clamping voltage (53 V @ 1 A); same 24 V VRWM, but 1.2 pF capacitance | Less suitable for >480 Mbps interfaces due to higher capacitance and slower response | Select UCLAMP2482PWQ.C when preserving USB 2.0 eye diagram or HDMI 2.0 timing margin is critical |
| SMA6J24A-Q | Unidirectional; larger SMA package (4.5 × 2.7 mm); no multi-channel integration | Requires discrete placement per line; not viable for space-constrained differential-pair routing | Choose UCLAMP2482PWQ.C for integrated, space-efficient, bidirectional protection of differential data buses |
Compared with SP1003-02WTG and SMA6J24A-Q, the UCLAMP2482PWQ.C delivers lower capacitance and tighter clamping in a miniature automotive-qualified package - enabling robust, high-fidelity protection of multi-gigabit differential interfaces without layout compromise.

FAQ
What is the maximum peak pulse current rating for UCLAMP2482PWQ.C?
The UCLAMP2482PWQ.C is rated for 5 A peak pulse current (IPP) under the 8/20 µs waveform per IEC 61000-4-5. This rating ensures reliable suppression of induced surges from nearby switching events or load dump coupling in automotive environments. The device maintains clamping performance within specification across its full operating temperature range, and UCLAMP2482PWQ.C test reports confirm no parametric shift after 1000 surge events at rated current.
Is UCLAMP2482PWQ.C compatible with lead-free reflow soldering processes?
Yes, UCLAMP2482PWQ.C supports standard lead-free reflow profiles per J-STD-020, with a maximum peak temperature of 260 °C for up to 30 seconds. Its SOT-563 package uses matte tin plating and passes intermetallic growth and solder joint reliability testing per AEC-Q200. UCLAMP2482PWQ.C has been validated in production automotive PCB assemblies using Type 3 solder paste and nitrogen-reflow atmospheres.
Does UCLAMP2482PWQ.C require external biasing or control signals?
No, UCLAMP2482PWQ.C operates passively and requires no external power, biasing, or control logic. It functions solely as a voltage-clamping device triggered by transient overvoltage exceeding its breakdown threshold. All protection behavior is inherent to its silicon PN junction design, and UCLAMP2482PWQ.C remains fully functional across its specified temperature and voltage ranges without configuration.
Can UCLAMP2482PWQ.C be used to protect MIPI D-PHY interfaces?
Yes, UCLAMP2482PWQ.C is suitable for MIPI D-PHY v2.1 and earlier versions operating at up to 2.5 Gbps per lane. Its 0.8 pF typical capacitance and sub-1 ns response time prevent distortion of fast edge rates required for LP and HS mode transitions. Layout guidelines for UCLAMP2482PWQ.C recommend direct placement at the connector with minimized trace length to maintain impedance continuity.
What is the failure mode of UCLAMP2482PWQ.C under overstress conditions?
Under sustained overvoltage beyond its absolute maximum ratings, UCLAMP2482PWQ.C fails short-circuit - a fail-safe mode that prevents downstream component damage by shunting excess current to ground. This behavior is verified per AEC-Q200 stress tests, and UCLAMP2482PWQ.C retains open-circuit integrity until the first electrical overstress event exceeds its energy handling limit.
