TISP4500H3BJR-S from BOURNS, in a SMB(DO-214AA). 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 | R | passive | R terminal of the symmetrical bidirectional thyristor overvoltage protector, with repetitive peak off-state voltage of ±350 V and breakover voltage of ±500 V, and all datasheet measurements are referenced to this terminal. |
| 2 | T | passive | T terminal of the symmetrical bidirectional thyristor overvoltage protector, which limits overvoltages on the line to ±500 V over the temperature range with a minimum off-state voltage of ±350 V. |
