# NRVS3MB

**onsemi** · Diodes - General Purpose · DO-214AA(SMB)

NRVS3MB from onsemi, in a DO-214AA(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 | Cathode | passive | Cathode terminal of the rectifier, identified by the polarity mark on the package. The datasheet gives no further electrical limits for this pin beyond the absolute maximum ratings (VRRM 1000 V, IF(AV) 3 A). |
| 2 | Anode | passive | Anode terminal of the rectifier, opposite the cathode mark. The datasheet gives no further electrical limits for this pin beyond the absolute maximum ratings (VRRM 1000 V, IF(AV) 3 A). |

## CAD (KiCad official)

- Symbol: `NRVS3MB`
- Footprint: `Diode_SMD:D_SMB`
- 3D model: DO-214AA(SMB) (KiCad packages3D, STEP)
- 3D model files: `nrvs3mb-etched.step` / `nrvs3mb-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `nrvs3mb.step` / `nrvs3mb.glb` are the bare package body.
