Product details
Overview
DT1042-04TS from Diodes Incorporated is a 4-channel low-capacitance TVS diode array designed for ESD protection of high-speed data lines. It delivers 6.2V minimum breakdown voltage, 6A peak pulse current (8/20μs), 0.65pF typical I/O-to-VSS capacitance, ±16kV IEC 61000-4-2 contact ESD rating, and 0.25Ω TLP dynamic resistance - enabling robust protection in USB 2.0, HDMI, and SIM port interfaces.
For engineers reviewing the DT1042-04TS datasheet, DT1042-04TS pinout, DT1042-04TS application, or DT1042-04TS equivalent, key selection criteria include low clamping voltage (7.7V at 6A), channel-to-channel capacitance matching (±0.02pF), TSOT26 package compatibility with high-density PCB layouts, and compliance with IEC 61000-4-4 Level-4 EFT and IEC 61000-4-2 ESD standards.
Technical Context
This TVS array uses bidirectional avalanche diode structures per channel to clamp transient overvoltages between I/O pins and VSS while maintaining sub-1pF signal path capacitance. Each channel operates independently with matched breakdown characteristics (6.2V min) and shares a common VCC rail for enhanced system-level surge coordination.
The device integrates four identical ESD protection paths in a single TSOT26 package, supporting simultaneous multi-line protection without cross-talk degradation. Its 0.25Ω TLP dynamic resistance ensures minimal voltage overshoot during fast-rising ESD events (100ns TLP pulse), critical for preserving signal integrity in 480Mbps USB 2.0 links.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage (VBR) | 6.2V min at 1mA - ensures reliable triggering above 5.0V DC operating voltage without false activation |
| Clamping Voltage (VC) | 7.7V typ at 6A, 8/20μs - limits transient voltage to safe levels for 3.3V/5V logic interfaces |
| I/O Capacitance (CI/O) | 0.65pF typ at 2.5V, 1MHz - preserves signal rise/fall times in USB 2.0 and HDMI 1.4a channels |
| ESD Rating | ±16kV contact, +27/−19kV air per IEC 61000-4-2 - exceeds industrial immunity requirements |
| Dynamic Resistance (RDIF) | 0.25Ω typ (I/O to VSS, TLP 10A) - minimizes voltage overshoot during nanosecond-scale ESD transients |
| Operating Voltage (VDC) | 5.5V max DC - compatible with 5V-tolerant and 3.3V I/O systems using VCC = 5V bias |
Pinout & Package
Package: TSOT26 - ultra-thin, 6-pin surface-mount package (2.90 × 1.60 × 0.95 mm) with matte tin-plated copper leadframe, moisture sensitivity level 1, and UL 94V-0 flammability rating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| I/O3 | Protected Input/Output Channel 3 | Third dedicated protection node; supports multi-lane interfaces like HDMI DDC or USB ID detection |
| I/O4 | Protected Input/Output Channel 4 | Fourth isolated protection channel; allows full-port coverage for 4-wire SIM card interfaces |
| VCC | Positive Supply Terminal | Bias rail for internal avalanche structure; must be connected to system VCC (≤5.5V) for proper clamping operation |
| VSS | Ground Reference Terminal | Common return path for all four channels; requires low-inductance connection to system ground plane |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar TVS diode array applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SP1002-04UTG | Higher CI/O (1.0pF typ), lower IPP (4A), same TSOT26 package | Less suitable for >480Mbps USB 2.0 due to higher capacitance-induced jitter | Select when cost sensitivity outweighs speed requirements and EFT level-4 is not required |
| ESD5Z4.5T5G | Single-channel, 4.5V VRWM, 0.5pF, SOD-523 package | Requires four discrete devices; lacks integrated VCC bias coordination for multi-line clamping | Choose only for space-constrained single-line protection where channel coupling is undesirable |
Compared with SP1002-04UTG and ESD5Z4.5T5G, DT1042-04TS provides superior high-speed signal fidelity via 0.65pF capacitance and coordinated 4-channel clamping, while maintaining full IEC 61000-4-2/4-4 compliance - making it optimal for integrated USB/HDMI/SIM protection in portable electronics.

FAQ
What is the maximum DC operating voltage supported by DT1042-04TS?
The DT1042-04TS supports a maximum DC operating voltage of 5.5V between VCC and VSS, with a reverse working voltage (VRWM) of 5.0V between any I/O pin and VSS. This allows direct use in 3.3V and 5V logic systems without external voltage limiting circuitry, provided VCC is tied to the host system's supply rail within specification.
Can DT1042-04TS protect both unidirectional and bidirectional signal lines?
Yes - each I/O channel features symmetrical bidirectional avalanche clamping, enabling protection of both transmit and receive lines in full-duplex interfaces like USB 2.0 D+ and D−. The device does not require polarity assignment during layout, and clamps transients equally in either direction relative to VSS.
Is a decoupling capacitor required on the VCC pin?
No external decoupling capacitor is required on VCC for basic ESD protection functionality. However, adding a 100nF ceramic capacitor between VCC and VSS near the device improves high-frequency surge energy dissipation and stabilizes the bias rail during multi-channel simultaneous clamping events.
How does DT1042-04TS handle simultaneous ESD strikes on multiple I/O lines?
The device is characterized for independent channel operation: each I/O pin clamps to VSS with its own 0.25Ω dynamic resistance and 7.7V clamping voltage at 6A, even when all four channels activate concurrently. The shared VCC rail remains stable due to low internal impedance, ensuring no cross-channel voltage perturbation exceeding ±0.3V under worst-case TLP testing.
