# SMBJ6.5CA-TR

**STMicroelectronics** · ESD And Surge Protection (TVS/ESD) · SMB(DO-214AA)

SMBJ6.5CA-TR from STMicroelectronics, 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 | A1 | passive | Bidirectional (CA) TVS terminal with no polarity; the SMBJ6.5CA has a 6.5 V stand-off voltage (VRM), 7.2 V min breakdown voltage at 10 mA and 11.2 V max clamping voltage at 56 A (10/1000 µs). |
| 2 | A2 | passive | Second bidirectional (CA) TVS terminal with no polarity and the same ratings as the other terminal; there is no cathode band on bidirectional devices. |
