|---|---|---|---|---|
| FFF Compatibility | Housed in the identical SOT-143 package with pin-for-pin matching assignments (Pin 1: GND, Pin 2/3: I/O, Pin 4: VCC).Matches physical package dimensions and surface-mount land pattern directly.Functions as a 2-channel rail-to-rail TVS protection array with a 5V working voltage, covering standard 5V USB/data rail applications. | Uses the standard SOT-143 footprint and has pinout matching (Pin 1: GND, Pin 2/3: I/O, Pin 4: VCC).Identical package case and board layout requirements.Operates as a 2-channel steering diode array protecting lines up to 5V. | ||
 AI Summary | TPD2E001DZDR by Texas Instruments: Clamp Ipp Tvs Diode Surface Mount 4-SOP. | The SR05.TCT is a direct drop-in replacement that shares the same SOT-143 footprint and matching pin layout. It provides excellent circuit protection with up to 500W peak pulse power. Note that its per-channel input capacitance is slightly higher than the target.
| The CD143A-SR05 from Bourns is a robust drop-in alternative with matching pin configurations and SOT-143 footprint. It offers excellent thermal performance and 500W surge protection, though it features a higher capacitance.
