Product details
Overview
DT2041-04SO from Diodes Incorporated is a 4-channel low-capacitance TVS diode array designed for high-speed I/O line protection. It features 6V minimum reverse breakdown voltage, 1.0pF typical channel input capacitance, ±30kV IEC 61000-4-2 ESD rating, and 9V clamping voltage at 10A TLP pulse-used in USB 2.0, HDMI™, and Serial ATA interfaces.
For engineers reviewing the DT2041-04SO datasheet, DT2041-04SO pinout, DT2041-04SO application, or DT2041-04SO equivalent, key selection criteria include low signal distortion (1.0pF CT), robust multi-standard surge immunity (IEC 61000-4-2/4-5), and SOT26 footprint compatibility with high-density PCB layouts.
Technical Context
The DT2041-04SO implements four independent bidirectional TVS structures in a single SOT26 package, each protecting one I/O line against ESD and lightning-induced transients. Its low dynamic resistance (0.25Ω TLP) ensures rapid voltage clamping during 100ns pulses, while maintaining sub-1.5pF capacitance across 1MHz–1GHz bandwidths.
It operates within -55°C to +85°C ambient range and supports dual-path transient suppression: I/O-to-VSS (10A, 8/20μs) and VCC-to-VSS (12A, 8/20μs), with holding voltage of 5.5V and trigger voltage of 9V-enabling reliable latch-up immunity in 5V logic systems.

IC Role / Device Role / Timing Role: Dual-path protector handling both signal-line transients and VPP supply surges. Use Value: Separate VCC-to-VSS (12A) and I/O-to-VSS (10A) ratings match IEEE 1394's asymmetric surge profile. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar TVS diode array applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ5.0A | Single-channel, 5.0V unidirectional, 600W PPP, 6.5pF CT | Requires four discrete devices; unsuitable for high-speed serial interfaces due to high capacitance | Select only for low-frequency DC power rail protection where space and signal integrity are non-critical |
| SP1003-04UTG | 4-channel, 5.5V bidirectional, 0.8pF CT, ±30kV ESD, but 12V VC@10A | Higher clamping voltage increases risk of downstream IC damage in 5V logic domains | Prefer when ultra-low capacitance is prioritized over clamping voltage margin in RF front-ends |
Compared with SMAJ5.0A and SP1003-04UTG, DT2041-04SO uniquely balances 1.0pF capacitance, 9V clamping, and integrated 4-channel SOT26 layout-making it optimal for space-constrained, high-speed digital port protection where both signal fidelity and robustness are required.

FAQ
What is the maximum operating temperature for DT2041-04SO?
The DT2041-04SO is rated for continuous operation from -55°C to +85°C ambient temperature. This range supports deployment in industrial enclosures, automotive infotainment head units, and consumer electronics subject to thermal cycling-verified per JESD22-A104 temperature cycling tests and JEDEC J-STD-020 moisture sensitivity level 1 handling.
Does DT2041-04SO support bidirectional signal lines like USB D+ and D−?
Yes, DT2041-04SO uses bidirectional TVS structures per channel, allowing symmetrical clamping on AC-coupled differential pairs without polarity concerns. Its 6V VBR and 9V VC@10A ensure safe operation across USB 2.0's ±150mV common-mode swing and 400mV differential amplitude, preserving eye diagram integrity.
How does the 0.25Ω dynamic resistance impact system-level ESD performance?
The 0.25Ω TLP dynamic resistance reduces voltage overshoot during 100ns ESD pulses by limiting IR drop across the device, resulting in tighter clamping control. In practice, this enables sustained protection at 10A peak current without exceeding 9V at the protected IC's pins-critical for safeguarding 5V-tolerant USB PHYs and HDMI™ receivers.
Is DT2041-04SO compatible with lead-free reflow soldering processes?
Yes, DT2041-04SO features matte tin finish annealed over copper leadframe, qualified for lead-free reflow per IPC/JEDEC J-STD-020. Its SOT26 package withstands peak temperatures up to 260°C for 30 seconds, and its moisture sensitivity level 1 eliminates bake requirements prior to assembly-ensuring compatibility with standard SnAgCu reflow profiles.
