Product details
Overview
DT1240V3-04LP from Diodes Incorporated is a 4-channel low-capacitance TVS diode array in U-DFN2510-10 package, designed for ESD and lightning surge protection of high-speed I/O lines. It delivers 6V minimum breakdown voltage, 5.5A peak pulse current (8/20µs), 0.55pF typical channel capacitance, 9V clamping at 5.5A, and ±16kV air/±14kV contact ESD immunity-ideal for HDMI 1.4 and USB 2.0 data lanes.
For engineers reviewing the DT1240V3-04LP datasheet, DT1240V3-04LP pinout, DT1240V3-04LP application, or DT1240V3-04LP equivalent, key selection criteria include sub-0.6pF input capacitance for signal integrity, dual-level ESD/lightning compliance (IEC 61000-4-2 & -4-5), TLP dynamic resistance under 0.3Ω, and verified 4-channel layout compatibility with high-density PCB routing near HDMI/USB connectors.
Technical Context
This device implements four independent bidirectional TVS structures between I/O pins and VSS, each featuring low-leakage silicon avalanche junctions optimized for fast transient response. Its clamping behavior is characterized by 8.8V ESD clamping (TLP, 10A) and 9–11V reverse clamping (5.5A, 8/20µs), with trigger voltage fixed at 9.5V to ensure reliable turn-on before IC damage thresholds.
The U-DFN2510-10 package enables compact placement directly at connector entry points, while its symmetric pinout (I/O on pins 1,2,4,5; VSS on pins 3,8; NC on 6,7,9,10) supports differential pair routing without crosstalk penalty. Thermal resistance of 360°C/W and 350mW power dissipation are validated on standard 2oz FR-4 pads per Diodes' recommended layout.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage (VBR) | 6V min at 1mA - ensures robust margin above 3.3V I/O rail while avoiding false triggering during normal operation |
| Clamping Voltage (VC) | 9V typ at 5.5A (8/20µs) - limits transient overvoltage to safe levels for 3.3V logic receivers |
| Input Capacitance (CI/O) | 0.55pF typ per channel - preserves signal integrity up to 480Mbps (USB 2.0) and 2.25Gbps (HDMI 1.4) |

Applications
| HDMI 1.4 Interface Protection | USB 2.0 Port Protection |
|---|---|
|
Use Scenario: Protecting TMDS clock and data pairs in HDMI 1.4 source devices against ESD events during cable insertion and handling.

Use Value: Enables full-speed (480Mbps) USB operation with pass/fail compliance on USB-IF eye diagram tests after ±15kV contact discharge stress. |
| Serial ATA (SATA II) Data Link | DVI-D Dual-Link Interface |
|
Use Scenario: Shielding SATA II transmitter/receiver differential pairs in storage controllers from board-level ESD coupling via backplane traces. IC Role / Device Role / Timing Role: TVS array mounted at SATA edge connector, providing symmetrical clamping to ground for both TX and RX lanes. Use Value: Prevents bit errors during 3Gbps SATA link training by limiting transient overvoltage to <9.5V, below receiver damage threshold. |
Use Scenario: Securing DVI-D dual-link pixel clock and 24-bit RGB data channels in digital signage controllers subjected to field ESD exposure. IC Role / Device Role / Timing Role: Four-channel protection applied to DVI clock (TMDS CLK) and three RGB data groups (R/G/B), each using one I/O pair. Use Value: Sustains 165MHz pixel clock stability with <1.5ps jitter increase post-ESD event, verified per DVI compliance test plan. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar TVS diode array applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA6J33A-Q | Single-channel, 33V VRWM, 600W PPP, 150pF CI/O - higher capacitance, lower channel count | Requires four discrete devices for same function; unsuitable for space-constrained HDMI layouts | Select only when protecting legacy 3.3V parallel buses where capacitance >100pF is acceptable |
| SP1003-04UTG | 4-channel, 3.3V VRWM, 0.5pF CI/O, but rated only to ±12kV ESD (IEC 61000-4-2) and no IEC 61000-4-5 rating | Lacks lightning surge capability; insufficient for industrial equipment with AC-coupled surge risk | Prefer for cost-sensitive consumer USB ports where lightning immunity is not mandated |
Compared with SMA6J33A-Q and SP1003-04UTG, DT1240V3-04LP uniquely combines quad-channel integration, sub-0.6pF capacitance, and dual-standard (ESD + lightning) compliance in a 2.5mm × 1.0mm footprint-enabling single-device protection for next-generation high-speed interfaces without signal degradation or layout compromise.

FAQ
What is the maximum operating temperature range for DT1240V3-04LP?
The DT1240V3-04LP operates reliably from -55°C to +150°C, with clamping voltage drift less than ±0.5V across this full range. Its thermal resistance (RθJA = 360°C/W) is specified for standard 2oz FR-4 PCB mounting per Diodes' recommended pad layout, enabling use in under-hood automotive infotainment modules and industrial control panels.
Can DT1240V3-04LP protect bidirectional differential signals like HDMI TMDS?
Yes-each of its four channels is fully bidirectional and symmetric, with identical forward/reverse clamping characteristics (VF = -0.85V at -15mA; VC = 9V at 5.5A). This ensures balanced transient suppression on HDMI TMDS+ and TMDS− lines without skew or common-mode disruption, preserving differential signaling integrity.
Is the U-DFN2510-10 package compatible with standard reflow profiles?
Yes-the device is qualified for IPC/JEDEC J-STD-020 moisture sensitivity level 1 and supports standard lead-free reflow profiles (peak 260°C, 60-second duration). Its NiPdAu (pins 1,2) and matte tin (pin 3) terminal finishes ensure solderability per MIL-STD-202, Method 208, with no special pre-bake required.
Does DT1240V3-04LP require external biasing or control signals?
No-it is a passive, unidirectional/bidirectional TVS array with no power supply or enable pins. It operates solely through avalanche breakdown at VBR ≥6V and requires only proper grounding to VSS (pins 3 and 8); no external circuitry, pull-ups, or configuration is needed for functional operation.
