Product details
Overview
DT1240A-08LP3810Q from Diodes Incorporated is an 8-channel low-capacitance TVS diode array designed for high-speed I/O line protection. It delivers 5V reverse standoff voltage, 5.5A peak pulse current (8/20µs), 0.6pF typical channel input capacitance, ±14kV contact ESD rating per IEC 61000-4-2, and is AEC-Q101 qualified for automotive use in HDMI 2.0 and USB 3.1 interfaces.
For engineers reviewing the DT1240A-08LP3810Q datasheet, DT1240A-08LP3810Q pinout, DT1240A-08LP3810Q application, or DT1240A-08LP3810Q equivalent, key selection criteria include clamping voltage at 5.5A (7.5V), dynamic resistance (0.25Ω), thermal resistance (360°C/W), and U-DFN3810-9 (Type B) package compatibility with high-density PCB layouts.
Technical Context
This device implements eight independent bidirectional TVS diodes in a single monolithic silicon array, each configured as a low-capacitance clamp between I/O and VSS. Its architecture enables simultaneous transient suppression across multiple high-speed data lanes without signal integrity degradation.
It operates within -55°C to +150°C ambient range and features symmetric clamping (VF = -0.85V, VC = 7.5V @ 5.5A), TLP-characterized dynamic resistance of 0.25Ω, and meets IEC 61000-4-5 (5.5A, 8/20µs) and IEC 61000-4-2 (±16kV air / ±14kV contact) immunity standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 3.3V - Maximum continuous operating voltage before conduction begins; ensures no leakage during normal USB/HDMI signaling. |
| Breakdown Voltage (VBR) | 5V min - Threshold where avalanche conduction initiates; sets margin above 3.3V logic rails. |
| Clamping Voltage (VC) | 7.5V typ @ 5.5A - Peak voltage seen by protected IC during 8/20µs surge; limits stress on downstream PHY transceivers. |
| Channel Input Capacitance | 0.6pF typ - Enables >5Gbps data rates (e.g., USB 3.1 Gen 1) without measurable eye diagram degradation. |
| ESD Rating | ±14kV contact / ±16kV air - Meets IEC 61000-4-2 Level 4; qualifies for front-panel and connector-facing protection zones. |
| Peak Pulse Power | 55W @ 8/20µs - Sustains lightning-induced surges per IEC 61000-4-5 without thermal runaway. |
| Dynamic Resistance | 0.25Ω - Low impedance path during transient events; reduces voltage overshoot and improves clamping speed. |
Pinout & Package
Package: U-DFN3810-9 (Type B), 3.8mm × 1.0mm × 0.5mm body, 9-terminal leadless plastic package with NiPdAu terminations, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 5, 7, 9 | I/O Channel Anode | Input/output connection for Channels 1–5; each tied to dedicated high-speed data line (e.g., USB D+, HDMI TMDS+). |
| 2, 4, 6, 8 | I/O Channel Cathode | Input/output connection for Channels 1–4; paired with odd pins to form bidirectional clamping paths to VSS. |
| 9 (center) | VSS (Ground) | Common cathode reference node; must be connected to low-inductance system ground plane for effective ESD dissipation. |
Key Features
| Feature | Design Value |
|---|---|
| 8-channel integration | Reduces board area by >70% vs. discrete TVS solutions while maintaining per-lane isolation and matching capacitance. |
| 0.6pF typical CI/O | Preserves signal integrity up to 10Gbps (HDMI 2.0) with <0.5dB insertion loss at 5GHz. |
| AEC-Q101 qualification | Validated for automotive infotainment and ADAS camera links requiring -40°C to +125°C operation and PPAP compliance. |
| TLP-characterized 0.25Ω RDIF | Ensures consistent clamping response across production lots; eliminates parameter drift due to process variation. |
| Green, halogen-free construction | Meets JESD22-A112 MSL1 handling requirements and supports lead-free reflow profiles (peak 260°C). |

Equivalent & Alternatives
The following parts are listed as comparable options for similar TVS diode array applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SZ1.8SMAT3G | Single-channel, 1.8V VRWM, 0.5pF CI/O, 3.5A IPP - lower voltage rating and no multi-channel integration. | Requires 8 discrete placements; unsuitable for space-constrained HDMI/USB layouts. | Select only when protecting isolated low-voltage analog sensors below 2V. |
| SP1006-08UTG | 8-channel, 5V VRWM, 0.8pF CI/O, 6A IPP - higher capacitance and same package but non-AEC-Q101 rated. | Lacks automotive qualification; limited to commercial-grade computing and consumer electronics. | Prefer for cost-sensitive industrial PCs where AEC-Q101 is not mandated. |
Compared with SZ1.8SMAT3G and SP1006-08UTG, the DT1240A-08LP3810Q uniquely combines AEC-Q101 qualification, 0.6pF capacitance, and 5.5A surge rating in a single U-DFN3810-9 package-enabling compact, automotive-grade protection for next-generation high-speed serial interfaces without design compromise.

FAQ
What is the maximum operating temperature for DT1240A-08LP3810Q?
The DT1240A-08LP3810Q is rated for continuous operation from -55°C to +150°C ambient temperature. This full-range specification supports deployment in under-hood automotive environments and thermally demanding industrial enclosures where junction temperatures may exceed 125°C under sustained surge conditions.
Does DT1240A-08LP3810Q require external biasing or control signals?
No. The DT1240A-08LP3810Q is a passive, bidirectional TVS array with no external control inputs, power pins, or bias requirements. It functions solely as a voltage-clamping device between each I/O pin and VSS, activating automatically when transient voltage exceeds its breakdown threshold of 5V.
How does the 0.6pF input capacitance impact USB 3.1 Gen 1 signal integrity?
At 0.6pF typical per channel, the DT1240A-08LP3810Q introduces negligible capacitive loading on 5Gbps SuperSpeed differential pairs. Measured insertion loss remains below 0.5dB at 2.5GHz, preserving eye height and jitter budget required for USB-IF compliance testing without requiring equalization or layout compensation.
Is DT1240A-08LP3810Q compatible with standard lead-free reflow profiles?
Yes. The device uses NiPdAu terminations and green molding compound rated for peak reflow temperatures up to 260°C per JEDEC J-STD-020. Its moisture sensitivity level is MSL1, allowing unlimited floor life and direct placement without pre-baking, fully supporting Class 3 IPC-A-610 assembly requirements.
