Product Description

Product Overview

The UMH33N is a digital transistor featuring built-in bias resistors, designed for muting applications. It integrates two DTC923TUB chips within a single SOT-363 (UMT6) package. Key advantages include a high breakdown voltage of 40V (BVEBO), low output ON resistance (typically 0.6), and the ability to configure an inverter circuit without external input resistors due to the integrated R1 (2.2k) biasing resistor. This product is suitable for muting functions.
