Product details
Overview
DT1240-04LPQ from Diodes Incorporated is a 4-channel low-capacitance TVS diode array designed for ESD and lightning surge protection of high-speed data lines. It delivers 6V reverse working voltage, 5.5A IEC 61000-4-5 peak pulse current, 0.55pF typical channel input capacitance, and 9.4V clamping voltage at 5.5A (8/20µs), making it suitable for automotive-grade USB 2.0 and HDMI interfaces.
For engineers reviewing the DT1240-04LPQ datasheet, DT1240-04LPQ pinout, DT1240-04LPQ application, or DT1240-04LPQ equivalent, key selection criteria include low capacitance for signal integrity, AEC-Q101 qualification for automotive reliability, IEC 61000-4-2 ±14kV contact ESD rating, and U-DFN2510-10 package compatibility with high-density PCB layouts.
Technical Context
This device implements four independent bidirectional TVS channels in a single monolithic silicon structure, each configured as a low-capacitance avalanche diode pair between I/O and VSS. Its 0.25Ω TLP dynamic resistance ensures rapid voltage clamping during transient events, while the 5.5V reverse working voltage enables use on 5V-tolerant high-speed buses without leakage concerns.
The U-DFN2510-10 package integrates eight active terminals (four I/O pins + two VSS pins) plus four no-connect terminals to support symmetric layout and thermal dissipation. Its design meets IATF 16949 manufacturing standards and supports PPAP documentation for automotive Tier-1 supply chain requirements.

Equivalent & Alternatives
The following parts are listed as comparable options for similar TVS diode array applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA6J5.0A-Q | Single-channel, 5.0V VRWM, 600W PPP, SMA package (4.5mm × 2.7mm) | Larger footprint, higher capacitance (~30pF), unsuitable for >100Mbps interfaces | Select only when board space allows larger package and speed requirements are ≤10Mbps |

FAQ
What is the maximum operating temperature for DT1240-04LPQ in continuous use?
The DT1240-04LPQ is rated for continuous operation from -55°C to +150°C ambient temperature. Its thermal resistance (RθJA = 360°C/W) assumes mounting on a standard FR-4 PCB with Diodes' recommended 2oz copper pad layout. Derating begins above +125°C ambient per Figure 1 in the datasheet, reducing peak pulse power linearly to 50% at +150°C.
Can DT1240-04LPQ be used on 3.3V logic interfaces without risk of false triggering?
Yes. With a 5.5V reverse working voltage (VRWM) and 6V minimum breakdown voltage (VBR), DT1240-04LPQ provides a 2.2V margin above 3.3V nominal rails. Its leakage current is limited to 0.5μA at 5V, ensuring negligible loading on 3.3V I/O drivers and compatibility with low-power microcontrollers and FPGAs.
How does the U-DFN2510-10 package affect PCB layout for high-speed signals?
The U-DFN2510-10's 0.5mm pitch and symmetrical pinout (I/O pins on two opposing edges, dual VSS on center) enable minimal trace length and balanced differential routing. Its low profile (0.575mm height) reduces parasitic inductance, and the exposed copper paddle improves thermal transfer-critical for maintaining clamping performance during repeated ESD strikes.
Is DT1240-04LPQ compatible with lead-free reflow profiles per JEDEC J-STD-020?
Yes. The device is qualified to moisture sensitivity level 1 per J-STD-020 and supports standard lead-free reflow profiles with peak temperatures up to 260°C. Its NiPdAu over copper leadframe ensures robust solderability per MIL-STD-202, Method 208, and eliminates intermetallic growth concerns during multiple reflow cycles.
