UPA831TC Datasheet, PDF (1/2 Pages) NEC – NPN SILICON EPITAXIAL TRANSISTOR WITH 2 DIFFERENT ELEMENTS IN A FLAT-LEAD 6-PIN THIN-TYPE ULTRA SUPER MINIMOLD PACKAGE

PRELIMINARY DATA SHEET
NPN SILICON EPITAXIAL TWIN TRANSISTOR UPA831TC
FEATURES
• SMALL PACKAGE OUTLINE:
1.5 mm x 1.1 mm, 33% smaller than conventional
SOT-363 package
• LOW HEIGHT PROFILE:
Just 0.55 mm high
• FLAT LEAD STYLE:
Reduced lead inductance improves electrical
performance
• TWO DIFFERENT DIE TYPES:
Q1 - Ideal oscillator transistor
Q2 - Ideal buffer amplifier transistor
DESCRIPTION
The UPA831TC contains one NE856 and one NE681 NPN
high frequency silicon bipolar chip. NEC's new ultra small TC
package is ideal for all portable wireless applications where
reducing board space is a prime consideration. Each transistor
chip is independently mounted and easily configured for oscil-
lator/buffer amplifier and other applications.
