Product details
Overview
UCLAMP4014P.TNT from Semtech is a 4-line bidirectional ESD protection diode array in an SGP2510P8 package, rated for ±40V working voltage and ±18kV IEC 61000-4-2 contact ESD immunity. It features 2Ω typical dynamic resistance, <10nA reverse leakage at 40V, and low clamping voltage (57V at 3A) for VBus line protection in space-constrained LCD TV and industrial equipment interfaces.
For engineers reviewing the UCLAMP4014P.TNT datasheet, pinout, applications, or equivalent options, key selection criteria include its flow-through 10-pin layout, ±40V standoff, 57V clamping at 3A, 105pF junction capacitance, and RoHS-compliant NiPdAu lead finish - all critical for high-density USB/DisplayPort interface protection.
Technical Context
The UCLAMP4014P.TNT integrates four independent bidirectional TVS diodes in a single monolithic silicon-avalanche structure, each channel rated for ±40V reverse standoff and capable of clamping transients to ≤57V at 3A (8/20μs). Its SGP2510P8 package enables flow-through routing with 0.5mm pitch and 2.5×1.0mm footprint.
Designed specifically for board-level ESD suppression per IEC 61000-4-2 Level 4, it delivers 18kV contact discharge robustness without degradation, leveraging large-junction-area avalanche technology and low dynamic resistance (2Ω) to minimize voltage overshoot during fast transients.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | ±40V - defines maximum continuous DC or signal swing the device blocks without conduction |
| ESD Rating | ±18kV contact per IEC 61000-4-2 - certifies immunity to human-body-model-like discharges in end-equipment testing |
| Clamping Voltage | 57V at 3A (8/20μs) - peak voltage seen by protected IC during transient, directly limiting stress on downstream logic |
| Junction Capacitance | 105pF at 0V - impacts high-speed signal integrity; suitable for USB 2.0 and LVDS but not USB 3.0+ |
| Dynamic Resistance | 2Ω typical - determines voltage rise per amp of transient current (ΔV = I × Rdyn) |
| Leakage Current | <10nA at 40V - ensures negligible DC loading on bias or reference lines |
| Package | SGP2510P8 (2.5 × 1.0 × 0.6mm) - enables compact, flow-through PCB layout with 0.5mm pin pitch |
Pinout & Package
The UCLAMP4014P.TNT is housed in a 10-pin SGP2510P8 surface-mount package measuring 2.5 mm × 1.0 mm × 0.60 mm, with lead-free NiPdAu plating and UL 94V-0 molding compound. Pin 1 is marked by laser indicator at the top-left corner (bottom view).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1, 2, 4, 5 | Anode of Channel 1–4 | Each connects to one protected line (e.g., D+, D−, VBus, ID); bidirectional operation allows AC-coupled signals |
| Pin 3 & Pin 8 | Cathode common rail | Shared cathode node tied to system ground or low-impedance return path for all four channels |
| Pins 6, 7, 9, 10 | No Connect (NC) | Internally unconnected; must be left floating or grounded per layout guidelines - no electrical function |
Key Features
| Feature | Design Value |
|---|---|
| Flow-through package architecture | Enables straight-line PCB trace routing across pins 1–2–4–5, reducing parasitic inductance and simplifying layout in tight spaces |
| ±18kV IEC 61000-4-2 contact ESD rating | Meets highest industrial and consumer immunity requirement without derating or external components |
| 2Ω typical dynamic resistance | Minimizes clamping voltage rise under high-current transients, protecting sensitive 3.3V/5V interface ICs |
| 105pF junction capacitance at 0V | Preserves signal integrity for USB 2.0 (480 Mbps), HDMI DDC, and LVDS display interfaces |
| Lead-free NiPdAu termination | Ensures reliable solder wetting and intermetallic formation for automated reflow assembly |
Applications
| USB VBus Protection | LCD Panel COG Interface |
|---|---|
Use Scenario: Protecting USB Type-A/B upstream VBus lines against ESD events during hot-plug insertion in set-top boxes and docking stations. IC Role / Device Role: Bidirectional TVS clamp placed between connector and power switch or load switch IC. Use Value: Limits VBus surge to ≤57V at 3A, preventing latch-up or overvoltage damage to 5V-rated power management ICs. | Use Scenario: Shielding fine-pitch Chip-on-Glass (COG) driver IC bond pads on LCD TV panels from handling ESD during manufacturing and assembly. IC Role / Device Role: Low-capacitance ESD shunt mounted directly at COG flex cable entry point. Use Value: 105pF capacitance avoids signal distortion on high-speed COG data buses while sustaining ±18kV contact discharge. |
| Industrial HMI Display Port | Set-Top Box HDMI DDC Lines |
Use Scenario: Safeguarding LVDS or mini-LVDS timing and data lines connecting mainboard to front-panel displays in factory HMIs. IC Role / Device Role: Four-channel ESD suppressor placed at display connector to protect FPGA or ASIC video output pins. Use Value: Flow-through pinout allows daisy-chained routing without stubs, preserving edge rates up to 150 MHz. | Use Scenario: Guarding HDMI DDC (I²C) clock and data lines against ESD in consumer set-top boxes exposed to frequent cable swaps. IC Role / Device Role: Dual-line ESD protection for bidirectional 3.3V I²C bus operating at 100 kHz–400 kHz. Use Value: ±40V working voltage accommodates I²C pull-up to 3.3V with margin; <10nA leakage prevents bus contention. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SP1006-04UTG | Lower working voltage (±24V), higher capacitance (130pF), same SGP2510P8 package | Better suited for 3.3V-only interfaces; less margin for 5V VBus lines | Select when protecting sub-24V logic rails where tighter clamping (33V @ 3A) outweighs reduced voltage headroom |
| TPD4E001DPVR | Higher working voltage (±5.5V), lower capacitance (0.6pF), 4-channel SC-70-6 package | Optimized for high-speed serial links (USB 3.0, PCIe); unsuitable for 5V VBus | Choose only for ultra-low-capacitance requirements below 1pF - not a functional replacement for VBus protection |
Compared with UCLAMP4014P.TNT, SP1006-04UTG offers lower clamping but sacrifices 5V system compatibility, while TPD4E001DPVR enables GHz-speed interfaces but cannot withstand VBus-level transients - making UCLAMP4014P.TNT uniquely balanced for cost-sensitive, mixed-voltage display and interface protection.

FAQ
What is the maximum continuous reverse voltage rating for UCLAMP4014P.TNT?
The UCLAMP4014P.TNT has a maximum working voltage of ±40V, meaning it can continuously block up to +40V or −40V across each protected line without entering breakdown. This rating applies to Pins 1, 2, 4, and 5 versus the common cathode (Pins 3 and 8), and is verified per datasheet Electrical Characteristics table at 25°C.
Does UCLAMP4014P.TNT meet IEC 61000-4-2 Level 4 ESD immunity?
Yes, UCLAMP4014P.TNT is rated for ±18kV contact discharge per IEC 61000-4-2, which exceeds Level 4 (±8kV contact) requirements. This performance is validated using standardized ESD gun testing with the return path connected to the ESD ground plane, as specified in the official Semtech test notes.
Can UCLAMP4014P.TNT be used to protect USB 2.0 data lines (D+ and D−)?
UCLAMP4014P.TNT is not recommended for USB 2.0 differential data lines due to its 105pF junction capacitance, which would degrade signal integrity and fail eye-diagram compliance. It is intended for VBus, ID, or other lower-speed lines; use UCLAMP2804P.TNT (25pF) or similar low-C variants for D+/D− protection.
What is the thermal limit for UCLAMP4014P.TNT during repeated ESD events?
The UCLAMP4014P.TNT has a junction temperature range of −55°C to +125°C and is rated for non-repetitive pulse operation. While it withstands single ±18kV strikes without degradation, repeated high-energy events may cause thermal accumulation; ensure adequate copper pour and spacing per Semtech's layout guidelines to maintain TJ < 125°C.
Are Pins 6, 7, 9, and 10 on UCLAMP4014P.TNT required to be connected?
No - Pins 6, 7, 9, and 10 are No Connect (NC) terminals per the UCLAMP4014P.TNT datasheet. They must remain unconnected on the PCB; grounding or routing them may introduce parasitic coupling or violate internal die isolation. The functional pins are strictly Pins 1, 2, 3, 4, 5, and 8.
