TPD2E001 ESD Protection Diodes and Mixed ICs

TPD2E001 protection devices and related listings

Shop TPD2E001-family surface-mount ESD protection devices by the exact selected part number, package and pack size. This collection also contains other protection-array options and unrelated ICs and finished modules. The collection name is a search starting point, not a guarantee that every product or variant is a TPD2E001 or can replace one.

Compare the protection-device options

• TPD2E001 selections: Listings identify DRLR in SOT-553, DZDR in a SOT-23-4/SOT-143-style listing, and DRSR or DRST in SON-6, plus a DRYR selection. Check the actual manufacturer ordering code, pinout and footprint against your board before ordering; seller package labels conflict in some descriptions.
• Different channel counts: Certain multi-model products let you choose TPD2E001, TPD3E001 or TPD4E001 as separate variants. The title listing several codes does not mean a mixed kit. Match the selected number of protected lines, pin configuration and system supply range.
• Pack size: Offers include 1-, 5-, 10-, 20-, 50- and 100-piece options, depending on the listing. An option labeled Color, Model Number or Resistance may actually designate the exact part number or quantity. Read the selected variant, not just the headline quantity.
• Other devices in this collection: One broad component listing includes regulator, monitor, driver and other non-ESD variants; other listings offer LTK audio amplifier ICs or boards, ADL5801 RF mixer modules, FM receiver boards and a relay module. Those selections are not TPD2E001 protection arrays and require their own application-specific specifications.

Selection and compatibility

For an ESD array, compare the exact ordering code's reverse working voltage, breakdown and clamping conditions, input capacitance, leakage, channel count, pin mapping and package dimensions with the protected interface and IC limits. For an amplifier, mixer, radio or relay selection, use that product's own power, interface and mechanical requirements instead. Claims of originality, certifications or an IEC discharge level in an individual seller listing are not verified guarantees across this collection.

Frequently asked questions

Are DRLR, DZDR and DRSR drop-in substitutes? Do not assume so. Their listed packages and pinouts differ; confirm the exact datasheet and board footprint.

Does a multi-model title mean I receive every model? Usually the selectable variant specifies one model and quantity. Check the option shown in your cart.

Is a TPD3E001 or TPD4E001 option the same as TPD2E001? No. These are separately labeled protection-device choices with different line counts and potentially different pin layouts.

Can the audio or RF modules protect a signal line? No. They are different functional products, not substitutes for a discrete ESD protection array.
