2N3440 - NPN LOW POWER SILICON TRANSISTOR

Download the 2N3440 datasheet PDF. This datasheet also covers the 2N3439 variant, as both devices belong to the same npn low power silicon transistor family and are provided as variant models within a single manufacturer datasheet.

General Description

This family of high-frequency, epitaxial planar transistors feature low saturation voltage.

These devices are also available in TO-39 and low profile U4 and UA packaging.

Key Features

  • JEDEC registered 2N3439 through 2N3440 series.
  • JAN, JANTX, JANTXV, and JANS qualifications are available per MIL-PRF-19500/368.
  • RoHS compliant versions available (commercial grade only).
  • V CE(sat) = 0.5 V @ IC = 50 mA.
