Product details
Overview
DMF05LCFLPA from Diodes Incorporated is a 5-line common-anode ESD protection diode array in 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 digital interfaces including USB 1.1, SPI, I²C, and UART.
For engineers reviewing the DMF05LCFLPA datasheet, DMF05LCFLPA pinout, DMF05LCFLPA application, or DMF05LCFLPA equivalent, key selection criteria include low capacitance for signal integrity, sub-miniature 1.6×1.6mm footprint for space-constrained PCBs, common-anode architecture for multi-line bidirectional protection, and automotive-qualified variant availability (DMF05LCFLPAQ).
Technical Context
This device implements five monolithic silicon avalanche diodes arranged in a common-anode configuration, enabling simultaneous bidirectional ESD suppression across five independent signal lines. Each channel features a 5.0V reverse standoff voltage and clamps to ≤9.5V at 1A per IEC61000-4-5 8/20µs waveform.
Thermal resistance is 280°C/W (junction-to-ambient on FR-4), supporting operation from –55°C to +150°C. The U-DFN1616-6 package uses NiPdAu-plated copper leadframe and green molding compound compliant with RoHS 3, halogen-free, and AEC-Q qualified for high-reliability applications.

Applications
| USB 1.1 Interface Protection | SPI/I²C Bus Protection |
|---|---|
Use Scenario: Protecting USB 1.1 data lines (D+, D–) on embedded host controllers against ESD events during cable insertion or handling. IC Role / Device Role / Timing Role: Bidirectional transient voltage suppressor placed directly at connector entry point, clamping surges before reaching PHY or microcontroller pins. Use Value: Prevents latch-up or permanent damage to USB transceivers while maintaining <12Mbps signal fidelity via 25pF capacitance. | Use Scenario: Safeguarding multi-drop SPI or I²C bus lines (SCLK, MOSI, MISO, SS, SDA, SCL) in sensor hubs and MCU peripheral interconnects. IC Role / Device Role / Timing Role: Five-channel ESD clamp with shared anode, allowing compact placement near bus connectors or header pins. Use Value: Enables reliable 400kHz I²C communication and 10MHz SPI clocking without added RC filtering or timing skew. |
| UART Debug Port Protection | Industrial Control I/O Protection |
Use Scenario: Securing UART TX/RX/CTS/RTS lines on debug headers used for firmware updates and field diagnostics in industrial gateways. IC Role / Device Role / Timing Role: Low-capacitance ESD array placed inline between connector and UART controller, preserving rise/fall times for 115.2kbps–1Mbps operation. Use Value: Eliminates need for separate TVS diodes per line, reducing BOM cost and assembly steps while meeting IEC61000-4-2 Level 4. | Use Scenario: Protecting isolated digital I/O lines (e.g., GPIO, enable, reset) in programmable logic controllers and motor drives exposed to factory floor ESD. IC Role / Device Role / Timing Role: Common-anode array providing coordinated clamping across five independent control signals tied to same ground reference. Use Value: Ensures deterministic reset behavior and prevents false triggering during maintenance or operator interaction. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection array applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SP1006-05UTG (Littelfuse) | Same U-DFN1616-6 package; 5.5V VRWM; 12pF CT; lower clamping (8.5V @ 1A) | Better for high-speed USB 2.0 (480Mbps) due to lower capacitance; not AEC-Q qualified | Select when signal bandwidth >100MHz is required and automotive qualification is unnecessary |
| ESD5Z5.0T1G (ON Semiconductor) | Single-channel SOD-523; 5.0V VRWM; 30pF CT; higher leakage (1µA vs. 0.1µA) | Requires five discrete placements; larger total footprint; less consistent channel matching | Choose only if board space allows discrete layout and tighter parametric matching is not critical |
Compared with SP1006-05UTG and ESD5Z5.0T1G, DMF05LCFLPA delivers optimal balance of low capacitance (25pF), industry-leading ±25kV ESD robustness, and integrated 5-channel layout - making it ideal for space-constrained, high-reliability USB/SPI/I²C designs where AEC-Q qualification may be needed later.

FAQ
What is the maximum operating temperature for DMF05LCFLPA?
The DMF05LCFLPA is rated for continuous operation from –55°C to +150°C. This range is validated per JEDEC standards and supports use in under-hood automotive environments and industrial enclosures with minimal thermal derating required on standard FR-4 PCBs with recommended pad layout.
Does DMF05LCFLPA require external biasing or control signals?
No. DMF05LCFLPA is a passive ESD protection device with no external power, bias, or control connections. It operates solely through avalanche breakdown during transient events and presents negligible leakage (<0.1µA at 5V) during normal operation, eliminating impact on system power budget or signal DC levels.
Can DMF05LCFLPA be used for USB 2.0 or USB 3.x interfaces?
DMF05LCFLPA is optimized for USB 1.1 (12Mbps) and low-speed interfaces. Its 25pF capacitance introduces measurable signal degradation above ~50MHz; for USB 2.0 (480Mbps) or USB 3.x, Diodes recommends SP1006-05UTG (12pF) or specialized high-speed arrays like AZ1045-04F.
How does the U-DFN1616-6 package enhance thermal performance?
The U-DFN1616-6 package incorporates an exposed thermal pad that, when soldered to a PCB ground plane, reduces thermal resistance from junction to ambient to 280°C/W. This enables sustained 5A peak pulse handling without thermal runaway and supports reflow compatibility per J-STD-020 Level 1 moisture sensitivity.
