Device Overview
ESD144B1W0201E6327XTSA1 is a Infineon Technologies TVS protection diode in a SG-WLL-2-3 package. Selection of this exact part is driven primarily by Working voltage (+/-18 V), Surge current (+/-3.5 A, 8/20 us), Package size (0201-class, 0.58 x 0.28 x 0.15 mm).
Selection-Critical Data
| Parameter | Confirmed Data | Why It Matters |
|---|---|---|
| Working voltage | ±18 V | Defines the electrical voltage envelope that must cover the intended operating or stress level. |
| Surge current | ±3.5 A, 8/20 µs | Defines the current-handling or drive capability that must meet the load while respecting current-path and thermal limits. |
| Package size | 0201-class, 0.58 x 0.28 x 0.15 mm | Determines PCB footprint, pinout, mechanical assembly and orderable-variant compatibility. |
| Device Type | TVS protection diode | Defines the device function or architecture that a compatible replacement must preserve before secondary ratings are compared. |
| Voltage Rating | +/-18 V | Defines the electrical voltage envelope that must cover the intended operating or stress level. |
Power-Device Selection Notes
At TVS protection diode, the device type defines the device function or architecture that a compatible replacement must preserve before secondary ratings are compared.
For package size, 0201-class, 0.58 x 0.28 x 0.15 mm is the approved value. Determines PCB footprint, pinout, mechanical assembly and orderable-variant compatibility.
Working voltage is +/-18 V. Defines the electrical voltage envelope that must cover the intended operating or stress level. +/-3.5 A, 8/20 us is the stated surge current value. Defines the current-handling or drive capability that must meet the load while respecting current-path and thermal limits.
For voltage rating, +/-18 V is the approved value. Defines the electrical voltage envelope that must cover the intended operating or stress level.
