UMA11NTR

The UMA11NTR from ROHM Semiconductor is a dual PNP pre-biased transistor array, also known as a digital transistor. This component integrates two transistors with built-in resistors into a single package, simplifying circuit design and reducing component count. It is constructed using an epitaxial planar type PNP silicon transistor structure.

Key electrical specifications include a maximum collector current of 100mA and a collector-emitter voltage of 50V. The device offers a typical DC current gain of 80 at 10mA and 5V, with a transition frequency of 250MHz. The power dissipation is rated at 150mW. The integrated resistors have a typical value of 4.7kΩ for R1 and 47kΩ for R2.

This transistor array is housed in a 5-TSSOP, SC-70-5, or SOT-353 package, designed for surface mounting. The UMT5 supplier device package code indicates its specific form factor. Its compact size and integrated functionality make it suitable for various digital logic applications where space and assembly costs are critical.

Absolute maximum ratings include a supply voltage of -50V and an input voltage of -30V. The junction temperature is rated up to 150°C, with a storage temperature range of -55°C to +150°C.
