Product details
Overview
DLP05LC-7-F from Diodes Incorporated is a unidirectional low-capacitance TVS diode designed for ESD and EFT protection of high-speed data lines, featuring 5 V reverse standoff voltage, 1.6 pF typical capacitance at 1 MHz, 11 V clamping voltage at 1 A peak pulse current, 300 W peak pulse power (8/20 µs), and SOT-23 surface-mount package-used in USB 2.0 data line protection.
For engineers reviewing the DLP05LC-7-F datasheet, DLP05LC-7-F pinout, DLP05LC-7-F application, or DLP05LC-7-F equivalent, key selection criteria include low signal-line capacitance, IEC 61000-4-2 Level 4 ESD immunity (±15 kV air/±8 kV contact), unidirectional polarity, thermal resistance (408 °C/W), and compatibility with automated SMT assembly on FR-4 PCBs.
Technical Context
This TVS diode operates as a clamping device in series with signal or power rails, triggering when transient voltage exceeds its 6.0 V minimum breakdown threshold to divert surge current away from sensitive ICs. Its unidirectional configuration supports DC-biased lines like USB D+/D− or VCC buses.
Designed for fast response (<1 ns), it meets IEC 61000-4-2 (ESD) and IEC 61000-4-4 (EFT) standards while maintaining minimal signal distortion due to sub-2 pF capacitance and low leakage (<20 µA at 5 V). Thermal derating follows a defined curve up to +150 °C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Standoff Voltage | 5 V - Maximum continuous operating voltage before clamping begins; matches standard 5 V logic and USB bus levels. |
| Breakdown Voltage (min) | 6.0 V - Ensures reliable turn-on during transients without false triggering under normal operation. |
| Clamping Voltage @ 1 A | 11.0 V - Limits downstream voltage stress during 8/20 µs surges, protecting 5 V-tolerant receivers. |
| Peak Pulse Power | 300 W - Sustains high-energy ESD/EFT events per IEC 61000-4-2 Level 4 and IEC 61000-4-4. |
| Total Capacitance | 1.6 pF @ 1 MHz - Enables use on USB 2.0 (480 Mbps), HDMI, and other high-speed interfaces without signal integrity loss. |
| Leakage Current | <20 µA @ 5 V - Minimizes standby power draw and avoids loading of high-impedance signal sources. |
| Operating Temp Range | −55 °C to +150 °C - Supports industrial and automotive under-hood applications with wide thermal margins. |
Pinout & Package
Package: SOT-23 (3-pin, surface-mount), JEDEC-compliant outline with matte tin-plated leads, moisture sensitivity level 1, and UL 94V-0 flammability rating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode | Connected to protected line (e.g., USB D+); forward-biased during negative transients. |
| Pin 2 | Cathode | Connected to ground; defines unidirectional conduction path and clamping reference. |
| Pin 3 | No Connect (NC) | Internally isolated; no electrical function-must remain floating per datasheet schematic. |
Key Features
| Feature | Design Value |
|---|---|
| Low Capacitance | 1.6 pF enables <480 Mbps USB 2.0 compliance without eye diagram degradation or timing skew. |
| IEC 61000-4-2 Level 4 ESD Protection | ±15 kV air discharge / ±8 kV contact discharge-meets highest system-level ESD immunity requirements. |
| Lead-Free & Halogen-Free Construction | RoHS 3 compliant with <900 ppm Br/Cl and <1000 ppm Sb-supports green manufacturing and end-of-life recycling. |
| SOT-23 Footprint | Standardized 3-pin package compatible with existing pick-and-place equipment and reflow profiles. |
Applications
| USB 2.0 Data Line Protection | VCC Bus Transient Suppression |
|---|---|
Use Scenario: Protecting D+ and D− differential pairs in portable USB peripherals against ESD events during hot-plug insertion. IC Role / Device Role: Unidirectional clamping TVS placed in series with each data line, referenced to ground. Use Value: Maintains 480 Mbps signal integrity while limiting transient voltage to ≤11 V, preventing PHY layer latch-up or damage. | Use Scenario: Safeguarding 5 V power rails feeding microcontrollers or sensors from coupled EFT bursts on adjacent traces. IC Role / Device Role: Parallel-connected TVS between VCC and GND, absorbing energy from fast-rising supply glitches. Use Value: Clamps surges within nanoseconds without affecting steady-state regulation, preserving brown-out immunity and reset stability. |
| HDMI TMDS Channel Protection | Industrial Sensor Interface Lines |
Use Scenario: Shielding HDMI 1.4 TMDS clock and data channels from electrostatic discharge during cable mating in AV equipment. IC Role / Device Role: One DLP05LC-7-F per channel (clock/data±), mounted close to connector with minimal trace length. Use Value: Sub-2 pF capacitance prevents rise/fall time degradation and maintains HDMI compliance up to 165 MHz pixel clock. | Use Scenario: Hardening analog or digital sensor outputs (e.g., RS-485, CAN FD stubs, or 4–20 mA loops) in factory automation panels. IC Role / Device Role: Bidirectional protection not required-unidirectional configuration suits DC-biased sensor outputs referenced to local ground. Use Value: Withstands repeated EFT exposure (IEC 61000-4-4) without parameter drift, ensuring long-term reliability in noisy environments. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ5.0A | Higher capacitance (≈35 pF), DO-214AC package, 400 W Ppk, bidirectional | Not suitable for >100 Mbps data lines; better for lower-speed power rail protection | Select when higher surge handling is needed and capacitance is not critical |
| TPD2E001DRYR | 2-channel array, 1.5 pF per line, 5 V standoff, same SOT-23-3 footprint but dual-line integration | Optimized for space-constrained dual-line protection (e.g., USB D+/D− together) | Choose for board area reduction where both data lines require identical protection |
Compared with SMAJ5.0A and TPD2E001DRYR, DLP05LC-7-F uniquely balances ultra-low capacitance (1.6 pF), unidirectional polarity, and SOT-23 footprint-making it optimal for single-line, high-speed, DC-biased interface protection where layout density and signal fidelity are prioritized.

FAQ
What is the maximum clamping voltage of DLP05LC-7-F under IEC 61000-4-2 ESD stress?
The DLP05LC-7-F does not specify clamping voltage under direct IEC 61000-4-2 testing; instead, its 11.0 V clamping voltage is measured at 1 A peak pulse current (8/20 µs waveform), which correlates to ESD events exceeding ±8 kV contact discharge. Actual clamping during ESD remains below 12 V per characterization data in DS30283 Rev. 13.
Can DLP05LC-7-F be used for bidirectional signal lines like RS-485?
No-DLP05LC-7-F is unidirectional and only protects against positive transients on the anode-to-cathode path. For bidirectional lines such as RS-485, a bidirectional TVS (e.g., DLP05S, or SMAJ5.0CA) is required to suppress both polarities of surge events.
Is the NC pin (Pin 3) required to be grounded or left floating?
Pin 3 is internally no-connect and must remain electrically floating per the device schematic and mechanical drawings. Grounding or routing this pin may cause unpredictable behavior or violate internal isolation design, and is explicitly prohibited in the datasheet.
How does the 408 °C/W thermal resistance impact PCB layout for sustained surge conditions?
The 408 °C/W junction-to-ambient thermal resistance assumes a standard FR-4 pad layout (1" × 1", 2 oz Cu). For repeated surges or elevated ambient temperatures, increasing copper area or adding thermal vias reduces effective RθJA, preventing junction temperature exceedance beyond 150 °C and ensuring long-term reliability.
