Product details

Three-channel rail-to-rail steering diode array for general-purpose ESD protection

Power line protection is included, making it suitable for clamping on supply rails as well as signal lines.

Active lifecycle — no near-term LTB risk for production BOMs

The base product number is TPD3E001, so any future package or tape-and-reel variant changes would carry the same die and electrical characteristics.

90W peak pulse — sizing the clamp for your transient budget

For a 5.5V rail, a 90W clamp translates to roughly 16A peak pulse current before the device exceeds its thermal limit. That is adequate for typical ESD strikes and small induced surges on low-voltage signal lines, but not for direct lightning or high-energy industrial transients. If your application sees repetitive surges or higher energy, you would need a larger TVS or a multi-stage protection scheme.

SOT-553 footprint — board-area and assembly considerations

The SOT-553 package (supplier device package SOT-5) is a very small 5-pin surface-mount package, roughly 1.6 mm × 1.6 mm.

Frequently asked questions

What is the peak pulse power of TPD3E001DRLR?

The TPD3E001DRLR is rated for 90W peak pulse power per channel under the standard 8/20 µs surge waveform. That is the maximum instantaneous power the device can dissipate in a single transient event before damage.

Is TPD3E001DRLR RoHS compliant?

The evidence does not list a specific RoHS compliance statement for this order code. However, the part is an active, current-production device from Texas Instruments, and TI's standard policy is that lead-free (RoHS-compliant) finishes are used unless otherwise noted. For a formal compliance certificate, request the TI RoHS/REACH declaration tied to the date code on your reel.

What are the alternatives to TPD3E001DRLR?

Within the same steering-diode-array class, parts like the NUP2105LT1G or PESD5V0S1UB offer similar 5.5V standoff and SOT-23 or SOT-323 packages, but they differ in channel count and peak pulse capability. The TPD3E001DRLR's three unidirectional channels in a SOT-553 footprint are relatively unique; a direct pin-compatible drop-in is not common. For a dual-source strategy, evaluate the TPD3E001 series' other package variants (e.g., TPD3E001DRLR is the SOT-553 tape-and-reel version) or look at the TPD4E001 family if four channels are acceptable.

Does TPD3E001DRLR have low capacitance for high-speed signals?

The evidence does not provide a capacitance value for this part. Steering-diode arrays of this class typically have low capacitance (around 1–3 pF per channel) to avoid loading high-speed data lines, but without a cited spec, you should confirm the capacitance from the full datasheet before using it on USB 2.0, HDMI, or gigabit Ethernet lines.

Is TPD3E001DRLR bidirectional?

No, the TPD3E001DRLR is a unidirectional steering diode array. It has three unidirectional channels, meaning each channel protects against positive transients relative to ground. For bidirectional protection (e.g., on AC-coupled or differential signal lines), you would need a bidirectional TVS or a back-to-back configuration.
