Texas Instruments TPD4E1B06DCKR

Overview

TPD4E1B06DCKR from Texas Instruments is a 4-channel bidirectional ESD protection diode array in SC70-6 (DCK) package, delivering ±12 kV IEC 61000-4-2 contact/±15 kV air-gap ESD immunity, 0.7 pF typical I/O capacitance, and ultra-low 0.5 nA max leakage current for precision analog and high-speed interfaces including USB2.0, LVDS, and HDMI.

For engineers reviewing the TPD4E1B06DCKR datasheet, TPD4E1B06DCKR pinout, TPD4E1B06DCKR application, or TPD4E1B06DCKR equivalent, key selection criteria include leakage-sensitive signal integrity, sub-1pF capacitance for >3.4 Gbps data rates, industrial temperature support (–40°C to 125°C), and compact 2.0 mm × 2.1 mm SC70 footprint with verified 6-pin DCK pin mapping.

Technical Context

The TPD4E1B06DCKR implements a back-to-back diode topology per channel to support bidirectional signaling across –5.5 V to +5.5 V, with integrated steering diodes enabling safe clamping during cross-pin transients. Its passive operation activates only during fast ESD events (>10 ns rise time), clamping to ≤14.5 V at 3 A surge (8/20 µs).

Each of the four protected I/O lines features matched 0.7 pF capacitance (1 MHz, 2.5 V bias), ≤1 Ω dynamic resistance, and 7–9.5 V breakdown voltage, ensuring minimal signal distortion while maintaining robust 3.0 A IEC 61000-4-5 surge capability and low 10.9 V clamp voltage at 1 A.

FAQ

What is the maximum operating voltage for TPD4E1B06DCKR?

The TPD4E1B06DCKR has a reverse stand-off voltage (VRWM) of ±5.5 V, meaning it can safely operate with signal swings from –5.5 V to +5.5 V without forward conduction. This makes TPD4E1B06DCKR compatible with standard 3.3 V and 5 V logic families, and ensures no DC loading on protected lines during normal system operation.

Does TPD4E1B06DCKR support differential signal pairs like USB2.0 D+/D–?

Yes, TPD4E1B06DCKR supports differential signaling via its bidirectional back-to-back diode architecture, which handles both polarities across –5.5 V to +5.5 V. Its 0.7 pF typical capacitance and matched channel characteristics preserve signal integrity on USB2.0 D+/D–, LVDS, and HDMI TMDS pairs - confirmed by TI's HDMI 1.4 eye diagram testing in the TPD4E1B06DCKR datasheet.

Is pin 5 of TPD4E1B06DCKR required to be connected?

No - pin 5 of TPD4E1B06DCKR is NC (not internally connected). It may be left floating or tied to ground per PCB layout best practices; neither choice affects electrical performance. TI's layout guidelines confirm pin 5 has no internal bond wire and does not influence ESD clamping behavior or thermal performance of the TPD4E1B06DCKR device.

How does TPD4E1B06DCKR achieve ultra-low leakage current?

TPD4E1B06DCKR achieves 0.5 nA maximum leakage through optimized silicon process and diode junction design, minimizing reverse-bias current at 2.5 V bias - critical for high-impedance sensor nodes. This leakage value is measured and guaranteed across temperature (–40°C to 125°C), directly enabling precision analog applications like glucose meter biosensor front-ends where TPD4E1B06DCKR prevents measurement drift.

What is the thermal resistance of TPD4E1B06DCKR in its SC70 package?

The TPD4E1B06DCKR in SC70-6 (DCK) package has a junction-to-ambient thermal resistance (RθJA) of 227.3°C/W, and junction-to-board (RθJB) of 72.1°C/W. These values reflect its small footprint and reliance on PCB copper for heat dissipation - consistent with passive ESD devices that dissipate energy transiently rather than continuously, making thermal derating unnecessary for standard ESD event profiles.
