TISP61089BDR-S from BOURNS, in a SO-8. 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 | K1 | passive | Thyristor cathode K1 (Tip) of the SCR/diode pair; connects to the line Tip conductor and is clipped to the gate-referenced negative supply voltage. |
| 2 | G | input | Gate terminal connected to the SLIC negative supply VBATH (with a 220 nF decoupling capacitor) to set the negative protection voltage, supporting battery voltages down to -155 V. |
| 3 | NC | unconnected | No internal connection. |
| 4 | K2 | passive | Thyristor cathode K2 (Ring) of the SCR/diode pair; connects to the line Ring conductor and is clipped to the gate-referenced negative supply voltage. |
| 5 | K2 | passive | Thyristor cathode K2 (Ring), internally the same node as pin 4; connects to the line Ring conductor. |
| 6 | A | power_in | Anode (Ground) common to both protector elements; positive overvoltages are clipped to ground through diode forward conduction. |
| 7 | A | power_in | Anode (Ground) common to both protector elements, internally the same node as pin 6. |
| 8 | K1 | passive | Thyristor cathode K1 (Tip), internally the same node as pin 1; connects to the line Tip conductor. |
