# TISP4015L1AJR-S

**BOURNS** · Semiconductor Discharge Tubes (TSS) · DO-214AC

TISP4015L1AJR-S from BOURNS, in a DO-214AC. 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 (B) | passive | Terminal R, alternative line designator B, of the symmetrical bidirectional thyristor; the device is rated VDRM ±8 V and V(BO) ±15 V max for the '4015, and all measurements are referenced to this terminal. |
| 2 | T (A) | passive | Terminal T, alternative line designator A, of the symmetrical bidirectional thyristor; the '4015 is rated VDRM ±8 V and V(BO) ±15 V max, with a 2/10 µs peak surge current (ITSP) of ±150 A. |
