1.5SMBJ15CA
PAKER · ESD And Surge Protection (TVS/ESD) · SMB
1.5SMBJ15CA from PAKER, in a SMB. 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 | A1 | passive | Bidirectional TVS terminal 1 (no cathode band on CA parts) with 15 V reverse stand-off, 18.5 V min breakdown at 1 mA, and 24.4 V max clamping at 61.5 A peak pulse current. |
| 2 | A2 | passive | Bidirectional TVS terminal 2 (interchangeable with terminal 1) with 15 V reverse stand-off, 1 µA max leakage at VR, and 1500 W peak pulse power (10/1000 µs). |
