**TECH PUBLIC** · ESD And Surge Protection (TVS/ESD) · DFN1006-2

ESDL4151MX4T5G-TP from TECH PUBLIC, in a DFN1006-2. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | T1 | passive | Terminal 1 of the bidirectional ESD diode, connected to terminal 2 through the protection element; the datasheet rates the device at 15 V maximum reverse working voltage, 18 V minimum breakdown at 1 mA, and 0.7 pF maximum junction capacitance. |
| 2 | T2 | passive | Terminal 2 of the bidirectional ESD diode, connected to terminal 1 through the protection element; the datasheet rates the device for ±15 kV IEC 61000-4-2 air and contact discharge and 40 A IEC 61000-4-4 (EFT). |
