| PRELIMINARY DATA SHEET NPN SILICON EPITAXIAL TWIN TRANSISTOR 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 1 1.500.1 0.96 0.48 3 0.48 2 UPA831TC OUTLINE DIMENSIONS (Units in mm) Package Outline TC (TOP VIEW) 1.500.1 1.100.1 * * 0.20 +0.1 -0.05 6 * 5 4 PIN OUT 1. Collector (Q1) 2. Emitter (Q1) 3. Collector (Q2) 4. Base (Q2) 5. Emitter (Q2) 6. Base (Q1) 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 oscillator/buffer amplifier and other applications. 0.550.05 0.11+0.1 -0.05 Note: Pin 1 is the lower left most pin as the package lettering is oriented and read left to right.
