RD3.9ES - Zener Diode

Download the RD3.9ES datasheet PDF. This datasheet also covers the RD5 variant, as both devices belong to the same zener diode family and are provided as variant models within a single manufacturer datasheet.

General Description

NEC Type RD2.0ES to RD39ES Series are planar type diodes into DO-34 Package (Body length 2.4 mm MAX.) with DHD (Double Heatsink Diode) construction having allowable power dissipation of 400 mW.

Key Features

  • DO-34 Glass sealed package This diode can be inserted into a PC board with a shorter pitch (5 mm) 5 mm Cathode indication 25 MIN. φ 2.0 MAX. 25 MIN.
  • Planar process.
  • DHD (Double Heatsink Diode) construction.
  • VZ Applied E24 standard.
