Product details
Overview
DLP05LC-7 from Diodes Incorporated is a unidirectional low-capacitance TVS diode designed for ESD and EFT protection of high-speed data lines. It delivers 300 W peak pulse power (8/20 µs), 5 V reverse standoff voltage, 6.0 V minimum breakdown voltage, 11.0 V clamping voltage at 1 A, and 1.6 pF typical capacitance - enabling robust transient suppression in USB 2.0, HDMI, and Ethernet signal paths.
For engineers reviewing the DLP05LC-7 datasheet, DLP05LC-7 pinout, DLP05LC-7 application, or DLP05LC-7 equivalent, key selection criteria include its SOT-23 package compatibility, sub-2 pF capacitance for minimal signal integrity impact, IEC 61000-4-2 Level 4 ESD immunity, and unidirectional configuration for VCC-to-ground protection schemes.
Technical Context
The DLP05LC-7 employs a planar silicon avalanche structure optimized for fast response (<1 ns) to ESD transients while maintaining low dynamic capacitance. Its unidirectional architecture provides asymmetric conduction - blocking reverse current up to 5 V and clamping forward surges above 6.0 V - making it suitable for DC-biased signal lines like USB D+ and D−.
Thermal resistance is specified at 408 °C/W (junction-to-ambient, FR-4 board with 2 oz Cu), and derating follows a linear curve above +25 °C ambient, supporting operation from −55 °C to +150 °C. The device meets IEC 61000-4-4 (EFT) and IEC 61000-4-2 Level 4 (±15 kV air, ±8 kV contact) without external biasing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 300 W (8/20 µs waveform) - sustains single-event surge energy without failure in data-line protection applications |
| Reverse Standoff Voltage | 5 V - defines maximum continuous operating voltage before leakage exceeds 20 µA |
| Breakdown Voltage | 6.0 V min - ensures reliable triggering during ESD events while avoiding false clamping |
| Clamping Voltage | 11.0 V at 1 A - limits downstream IC stress to safe levels during transient events |
| Total Capacitance | 1.6 pF at 1 MHz, 0 V - preserves signal integrity on 480 Mbps USB 2.0 and similar high-speed interfaces |
| Leakage Current | 20 µA max at VRWM - minimizes standby power loss in battery-powered endpoints |
Pinout & Package
Package: SOT-23 (3-pin surface-mount, lead-free, halogen-free, JEDEC-compliant outline; dimensions per Diodes Inc. package drawing SOT23).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode | Connected to protected line (e.g., USB D+); conducts during positive transients toward ground |
| Pin 2 | Cathode | Connected to system ground; forms low-impedance path for surge current dissipation |
| Pin 3 | No Connect (NC) | Internally isolated; no electrical function - must remain unconnected in PCB layout |
Key Features
| Feature | Design Value |
|---|---|
| Low capacitance | 1.6 pF enables use on 480 Mbps USB 2.0 differential pairs without measurable eye diagram degradation |
| IEC 61000-4-2 Level 4 compliance | Withstands ±15 kV air discharge and ±8 kV contact discharge - meets industrial and consumer end-equipment requirements |
| Unidirectional configuration | Protects DC-biased lines (e.g., VCC, USB D+, HDMI TMDS) without interfering with normal signal polarity |
| SOT-23 footprint | Enables automated placement and reflow; compatible with standard pick-and-place equipment and IPC-7351B land patterns |
Applications
| USB 2.0 Data Lines | HDMI TMDS Channels |
|---|---|
Use Scenario: Protection of D+ and D− lines in portable USB hosts and peripherals against ESD during cable insertion. IC Role / Device Role: Unidirectional TVS clamp placed between signal line and ground, triggered only during positive transients. Use Value: 1.6 pF capacitance avoids signal rise-time degradation; 11.0 V clamping prevents damage to USB PHY transceivers rated for ≤12 V absolute maximum. | Use Scenario: Transient suppression on HDMI TMDS clock and data channels in set-top boxes and monitors. IC Role / Device Role: Low-capacitance shunt protector on each differential pair, referenced to chassis ground. Use Value: Sub-2 pF loading maintains 165 MHz pixel clock integrity; 300 W pulse rating handles hot-plug ESD events without latch-up. |
| VCC Bus Protection | Industrial Ethernet PHY Interfaces |
Use Scenario: Guarding 5 V supply rails in microcontroller-based sensors and IoT nodes against coupling-induced surges. IC Role / Device Role: Unidirectional clamp from VCC to ground, activated when rail voltage exceeds 6.0 V. Use Value: 5 V standoff allows direct connection to 5 V logic rails; 20 µA leakage ensures <1 µW standby power penalty. | Use Scenario: ESD hardening of 10/100BASE-TX transformer-coupled PHY lanes in factory automation gateways. IC Role / Device Role: Line-to-ground TVS on MDI side, placed after magnetics but before PHY input pins. Use Value: 11.0 V clamping aligns with PHY receiver overvoltage tolerance; SOT-23 size fits tight spacing near RJ45 connectors. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ5.0A | Higher capacitance (≈35 pF), higher clamping voltage (13.4 V), DO-214AC package | Not suitable for >100 Mbps data lines; better for lower-speed power/signal rails | Select when board space permits larger package and signal bandwidth is <10 Mbps |
| TPD2E001DRYR | 2-channel array, 1.5 pF per line, 5.5 V standoff, same SOT-23-3 footprint | Offers dual-line protection in identical footprint; requires matching layout for both D+ and D− | Select when protecting matched differential pairs where shared ground reference is acceptable |
Compared with SMAJ5.0A and TPD2E001DRYR, the DLP05LC-7 uniquely balances ultra-low capacitance (1.6 pF), compact SOT-23-3 layout, and unidirectional 5 V standoff - making it optimal for single-line, high-speed, cost-sensitive USB and display interface protection.

FAQ
What is the maximum operating temperature for DLP05LC-7?
The DLP05LC-7 is rated for continuous operation from −55 °C to +150 °C junction temperature. Its thermal resistance (RθJA) is 408 °C/W under standard JEDEC test conditions (FR-4 board, 2 oz Cu, 1″ × 1″ pad), and derating begins linearly above +25 °C ambient per Figure 1 in DS30283 Rev. 13-2.
Is DLP05LC-7 bidirectional or unidirectional?
The DLP05LC-7 is strictly unidirectional. It functions as an anode-to-cathode clamp, conducting only when the anode voltage exceeds the cathode by ≥6.0 V. It does not protect against negative transients on the protected line - confirmed by schematic symbol, pinout (Pin 1 = Anode, Pin 2 = Cathode), and electrical characteristics table showing no reverse breakdown specification.
Can DLP05LC-7 be used on USB 3.0 lines?
No - DLP05LC-7 is not recommended for USB 3.0 SuperSpeed (5 Gbps) differential lanes. Its 1.6 pF capacitance, while sufficient for USB 2.0 (480 Mbps), introduces unacceptable insertion loss and return loss at 2.5 GHz signaling frequencies. USB 3.0 requires sub-0.5 pF devices such as specialized arrays like SP1003-04UTG or NUP4201MR6T1G.
What does the "-7" suffix indicate in DLP05LC-7?
The "-7" suffix denotes tape-and-reel packaging: 3,000 units per 7-inch reel, 8 mm tape width, standard orientation for automated SMT placement. This matches Diodes Incorporated's ordering convention shown in the "Ordering Information" section of DS30283, where DLP05LC-7-F corresponds to the RoHS-compliant SOT-23 variant in this reel format.
