Product details
Overview
TPD4E001DCKR from Texas Instruments is a four-channel unidirectional ESD protection diode array in SC-70 (DCK) package, rated for ±8kV contact / ±15kV air-gap IEC 61000-4-2 Level 4 ESD suppression, with 1.5pF typical IO capacitance per channel and <1nA maximum leakage current - deployed on USB 2.0 D+/D− lines to protect host controllers from electrostatic discharge without signal integrity degradation.
For engineers reviewing the TPD4E001DCKR datasheet, TPD4E001DCKR pinout, TPD4E001DCKR application, or TPD4E001DCKR equivalent, key selection criteria include low-capacitance high-speed interface protection, VCC-referenced clamping architecture, thermal performance in SC-70 footprint, and compatibility with precision analog measurement systems requiring sub-nA leakage.
Technical Context
The TPD4E001DCKR implements a central ESD clamp topology with two series diodes per IO line tied to VCC and GND, enabling bidirectional transient shunting while maintaining low dynamic capacitance. Its breakdown voltage is 11V, and it clamps ±15kV IEC strikes to ≤VCC + 100V (positive) and ≤–100V (negative) at 45A peak pulse current.
It operates across –40°C to +85°C, supports 0.9V–5.5V supply range, and requires a 0.1µF ceramic bypass capacitor on VCC to stabilize clamping during surge events. The device functions passively - no bias or enable control - activating only during overvoltage transients above VBR or below –0.6V forward conduction threshold.
Key Specifications

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | IO1 | ESD-protected input/output channel - connects to first high-speed signal (e.g., USB D+) |
| 2 | VCC | Power-supply reference pin - must be bypassed to GND with 0.1µF ceramic capacitor for stable clamping |
| 3 | IO2 | ESD-protected input/output channel - connects to second high-speed signal (e.g., USB D–) |
| 4 | GND | Ground reference - provides return path for ESD current and stabilizes clamp voltage |
| 5 | IO3 | ESD-protected input/output channel - used for third signal (e.g., second USB port D–) |
| 6 | IO4 | ESD-protected input/output channel - used for fourth signal (e.g., second USB port D+) |
Key Features
| Feature | Design Value |
|---|---|
| Uni-directional clamp architecture | Enables VCC-referenced protection with lower capacitance than bi-directional TVS arrays |
| Central ESD clamp with dual-diode per line | Reduces parasitic loading while maintaining robust ±15kV air-gap clamping capability |

Applications
| USB 2.0 Interface Protection | Ethernet PHY Line Protection |
|---|---|
Use Scenario: Protecting D+/D− lines of upstream/downstream USB 2.0 ports against human-body ESD events during hot-plug insertion. IC Role / Device Role / Timing Role: Passive ESD clamp placed within 5mm of USB connector, shunting transients to VCC/GND before reaching USB transceiver. Use Value: 1.5pF capacitance prevents signal rise-time degradation; ±8kV contact rating ensures compliance with IEC 61000-4-2 Level 4. | Use Scenario: Safeguarding 10/100BASE-TX differential pairs (TX+/TX−, RX+/RX−) on Ethernet PHY side against cable-discharge events. IC Role / Device Role / Timing Role: Four-channel TVS array protecting two differential pairs - IO1/IO2 for TX, IO3/IO4 for RX - referenced to local PHY VCC. Use Value: Sub-1nA leakage avoids DC offset errors in transformer-coupled PHY receivers; low capacitance maintains 100MHz bandwidth. |
| LVDS Display Interface | Medical Glucose Meter Signal Path |
Use Scenario: Shielding 24-bit RGB LVDS video links between display controller and panel from handling-induced ESD during assembly or field service. IC Role / Device Role / Timing Role: One TPD4E001DCKR per 4-lane LVDS channel group - IO1–IO4 assigned to clock, DE, and two data lanes. Use Value: 1.5pF/channel ensures <1% signal distortion at 600Mbps; thermal resistance of 251.1°C/W (DCK) sustains reliability under continuous operation. | Use Scenario: Protecting analog sensor inputs (e.g., amperometric glucose strip interface) from ESD while preserving nanoamp-level current measurement accuracy. IC Role / Device Role / Timing Role: ESD guard on low-voltage analog front-end inputs - IO pins connected directly to electrode traces; VCC tied to precision reference rail. Use Value: ≤1nA leakage guarantees <0.1% error in 1µA full-scale measurements; 11V breakdown avoids false triggering during normal 0–1V sensor output swing. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPD4E1U06DCKR | Lower IO capacitance (0.5pF), higher IEC rating (±15kV contact), lower clamping voltage (VCC + 12V), eliminates need for external VCC bypass capacitor | Better suited for >5Gbps interfaces (e.g., USB 3.2 Gen 1) and noise-sensitive analog sensors where sub-pF loading is critical | Select TPD4E1U06DCKR when upgrading from TPD4E001DCKR for next-gen speed or tighter leakage budgets - pin-compatible SC-70 replacement |
| SMA6J40A-Q | Single-channel 40V standoff TVS, 600W peak power, 100pF capacitance - not multi-channel or low-C | Only suitable for discrete DC power rail or low-frequency signal protection; incompatible with high-speed data lines due to excessive capacitance | Use SMA6J40A-Q only for non-data applications like 12V/24V supply rail clamping - not a functional alternative for TPD4E001DCKR's high-speed role |
Compared with TPD4E001DCKR, TPD4E1U06DCKR delivers superior high-frequency performance and simplified layout via integrated clamping, while SMA6J40A-Q serves entirely different voltage-transient categories and cannot replace TPD4E001DCKR in data-line protection roles.

FAQ
What is the maximum operating temperature for TPD4E001DCKR?
The TPD4E001DCKR is specified for operation from –40°C to +85°C ambient temperature. This range is validated per JEDEC JESD22-A104 thermal cycling and JESD22-A108 high-temperature operating life testing. The SC-70 package exhibits a junction-to-ambient thermal resistance of 251.1°C/W, supporting reliable function within this envelope when mounted per TI's recommended land pattern and copper pour guidelines. TPD4E001DCKR must not exceed 150°C junction temperature under any condition.
Does TPD4E001DCKR require an external power supply to operate?
No, TPD4E001DCKR is a passive ESD protection device and does not require active power. Its VCC pin serves as a reference for the internal clamping diodes - it may be connected to system supply (0.9V–5.5V) or left floating. When connected, a 0.1µF ceramic capacitor to GND is mandatory for effective surge energy dissipation. TPD4E001DCKR draws only ≤1nA leakage current, eliminating standby power concerns. The device activates solely during overvoltage transients.
Can TPD4E001DCKR be used to protect USB 3.0 or higher-speed interfaces?
TPD4E001DCKR is not recommended for USB 3.0 (5Gbps) or faster interfaces. Its 1.5pF typical IO capacitance introduces measurable signal loss and jitter at frequencies above ~500MHz, and its ±15kV air-gap clamping response time exceeds optimal thresholds for SuperSpeed differential pair protection. For USB 3.x, TI recommends TPD4E1U06DCKR (0.5pF) or TPD6S300ADRVR. TPD4E001DCKR remains fully suitable for USB 2.0 (480Mbps) and other ≤240MHz applications as confirmed in the datasheet's Figure 5-1 and Section 7.2.1.
What is the pin configuration of TPD4E001DCKR in the SC-70 package?
TPD4E001DCKR in SC-70 (DCK) package has six pins arranged in a single row: Pin 1 = IO1, Pin 2 = VCC, Pin 3 = IO2, Pin 4 = GND, Pin 5 = IO3, Pin 6 = IO4 - matching the DBV SOT-23 top-view orientation per Figure 4-2 of the datasheet. This pinout is identical across TPD4E001DBVR and TPD4E001DCKR, enabling direct PCB footprint reuse. No exposed thermal pad is present in the DCK variant, unlike the DRS SON package.
How does TPD4E001DCKR differ from TPD2E001 or TPD6E001?
TPD4E001DCKR provides four independent ESD-protected channels, whereas TPD2E001 offers two channels and TPD6E001 offers six - all sharing identical electrical specs (1.5pF, ±8kV/±15kV, <1nA leakage) and SC-70/SOT-23 package options. Channel count determines routing flexibility: TPD4E001DCKR fits dual-USB 2.0 port protection (IO1/IO2 for Port 1, IO3/IO4 for Port 2), while TPD2E001 suits single-port or space-constrained designs, and TPD6E001 supports HDMI or multi-lane LVDS. All three are drop-in replacements within their channel-count constraints.
