Product details
Overview
DMF05LCFLPAQ from Diodes Incorporated is a 5-line common-anode ESD protection diode array in a U-DFN1616-6 package, rated for ±25kV IEC61000-4-2 contact/air discharge, with 5.0V reverse standoff voltage, 25pF typical capacitance at 0V, and 9.5V clamping voltage at 1A pulse. It protects high-speed I²C, UART, and audio interfaces in automotive infotainment and body control modules.
For engineers reviewing the DMF05LCFLPAQ datasheet, DMF05LCFLPAQ pinout, DMF05LCFLPAQ application, or DMF05LCFLPAQ equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, thermal resistance (280°C/W), clamping behavior under 5A IEC61000-4-5 surge, and real-world interface protection context for I/O line selection.
Technical Context
This device implements five monolithic silicon avalanche diodes configured in a common-anode arrangement, enabling bidirectional transient suppression on five independent signal lines referenced to a shared cathode node. Its low 25pF junction capacitance at 0V and 16pF at 2.5V supports signal integrity up to 100MHz in I²C and UART paths.
The U-DFN1616-6 package integrates an exposed thermal pad for enhanced power dissipation during 70W peak pulse events, while its 1.6×1.6mm footprint meets space-constrained automotive PCB layouts. Polarity is defined by a dot at Pin 1 and center pad notch per JEDEC MO-313.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ESD Rating (IEC61000-4-2) | ±25kV contact & air discharge - ensures robust immunity against human-handling ESD in assembly and field operation |
| Reverse Standoff Voltage (VRWM) | 5.0V - compatible with 3.3V and 5V logic I/O rails without leakage-induced false triggering |
| Clamping Voltage (VC @ IPP=1A) | 9.5V - limits transient overvoltage to safe levels below IC absolute maximum ratings during fast transients |
| Junction Capacitance (CT @ VR=0V) | 25pF typ - preserves signal edge rate and timing margin in 400kHz I²C and 3Mbps UART links |
| Peak Pulse Power (PPP) | 70W @ 8/20µs - sustains single-event surges from IEC61000-4-5 Level 3 (1kV) coupling networks |
| Thermal Resistance (RθJA) | 280°C/W - defines temperature rise under sustained low-duty-cycle pulses on standard FR-4 with recommended pad layout |
Pinout & Package
Package: U-DFN1616-6 (1.6 × 1.6 mm, 0.5 mm pitch, exposed thermal pad). Molded green compound, UL 94V-0 rated, MSL Level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Common Anode | Shared anode connection for all five diodes; ties to VCC or bias rail for bidirectional clamping |
| Pins 2–6 | Individual Cathodes | Each connects to one protected signal line (e.g., SDA, SCL, TX, RX, MIC_IN); conducts surge current to common anode |
| Exposed Pad | Thermal & Electrical Ground | Soldered to PCB ground plane for heat dissipation and low-inductance return path during ESD events |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 Qualified | Validated for automotive use with PPAP capability and IATF 16949 manufacturing - enables direct integration into ASIL-B systems |
| Low Capacitance (25pF) | Minimizes signal distortion and timing skew on high-speed digital buses without requiring layout compensation |
| ±25kV ESD Protection | Exceeds IEC61000-4-2 Level 4 - eliminates need for secondary board-level ESD mitigation in front-end I/O stages |
| Green, Halogen-Free | Meets RoHS 3, <900ppm Br/Cl, <1000ppm Sb - satisfies automotive OEM chemical compliance requirements (e.g., GMW3172, Ford WSS-M99P9999-A1) |
Applications
| I²C Bus Protection | UART Interface Protection |
|---|---|
Use Scenario: Protecting SDA/SCL lines in automotive camera modules and sensor hubs against ESD during cable mating/unmating. IC Role / Device Role / Timing Role: Bidirectional clamping diode array placed directly at connector entry point, before level translators or MCU pins. Use Value: Prevents latch-up or gate oxide damage in 3.3V I²C transceivers while maintaining 400kHz timing budget via 25pF loading. | Use Scenario: Shielding UART TX/RX lines between telematics control units and GPS/GNSS receivers from handling ESD. IC Role / Device Role / Timing Role: Signal-line ESD suppressor with common-anode architecture enabling shared VCC reference across multiple serial channels. Use Value: Ensures reliable 3Mbps UART communication without added propagation delay or signal attenuation. |
| Audio Line Protection | Automotive Body Control I/O |
Use Scenario: Guarding analog audio inputs (MIC_IN, LINE_IN) in head unit amplifiers against electrostatic discharge from user touch. IC Role / Device Role / Timing Role: Low-leakage (<0.1µA @ 5V) ESD clamp preserving DC bias integrity of electret microphone bias networks. Use Value: Maintains SNR >95dB by avoiding capacitive loading-induced high-frequency roll-off in 20Hz–20kHz band. | Use Scenario: Safeguarding GPIOs and wake-up inputs (e.g., door handle sensors, seat occupancy switches) in BCM modules. IC Role / Device Role / Timing Role: Five-channel transient suppressor with AEC-Q101 qualification ensuring reliability over -40°C to +125°C ambient. Use Value: Eliminates field returns due to ESD-induced resets by clamping transients to <9.5V before MCU input protection diodes activate. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPD2E001DRYR | Single-channel, 0.65pF capacitance, 5.5V VRWM, no AEC-Q101 rating | Limited to non-automotive, ultra-high-speed (USB 2.0) where sub-1pF loading is critical | Select only when system-level ESD testing permits lower clamping energy and automotive qualification is unnecessary |
| SP1002-04UTG | 4-channel, 15pF CT, 5.5V VRWM, AEC-Q101 qualified, but lacks common-anode topology | Requires separate VCC routing per channel; less optimal for shared-bus architectures like I²C | Prefer when discrete cathode routing simplifies layout or when 15pF loading is mandatory for >10MHz signals |
Compared with TPD2E001DRYR and SP1002-04UTG, DMF05LCFLPAQ uniquely combines five-channel common-anode topology, AEC-Q101 qualification, and 25pF capacitance-making it the only choice for space-constrained, automotive-grade I²C/UART bus protection where shared VCC bias and MSL Level 1 handling are required.

FAQ
What is the maximum operating temperature range for DMF05LCFLPAQ?
The DMF05LCFLPAQ operates reliably from –55°C to +150°C, meeting extended automotive temperature requirements. This range covers under-hood and cabin-mounted applications, including engine control sensors and infotainment displays, and is validated per AEC-Q101 stress test conditions including temperature cycling and high-temperature operating life.
How does the common-anode configuration affect circuit implementation?
The common-anode structure requires connecting Pin 1 to the local VCC rail (e.g., 3.3V or 5V), allowing each cathode (Pins 2–6) to clamp positive transients to VCC and negative transients to ground via internal diode conduction paths. This eliminates the need for external bias components and simplifies PCB routing versus dual-rail TVS arrays.
Is the exposed thermal pad electrically isolated or grounded?
The exposed thermal pad is electrically connected to the common anode (Pin 1) and must be soldered to a PCB copper pour tied to the same VCC net. This provides both thermal dissipation and low-inductance surge current return, improving clamping response time and reducing voltage overshoot during 8/20µs transients.
Can DMF05LCFLPAQ replace discrete 0402 TVS diodes in existing designs?
Yes - its 1.6×1.6mm U-DFN1616-6 footprint replaces five discrete 0402 ESD diodes, reducing PCB area by ~65% and assembly cost. Layout adaptation requires updating land patterns to match the 0.5mm pitch and thermal pad dimensions, but no changes to schematic connectivity are needed beyond consolidating anode connections.
