Device Overview
Designed as a TVS protection diode, Infineon Technologies ESD111B1W0201E6327XTSA1 uses the SG-WLL-2-3 package. For substitution or design review, the strongest comparison points are Working voltage (+/-5.5 V), Surge current (+/-2 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 | ±5.5 V | Defines the electrical voltage envelope that must cover the intended operating or stress level. |
| Surge current | ±2 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 | +/-5.5 V | Defines the electrical voltage envelope that must cover the intended operating or stress level. |
Power-Device Selection Notes
