UMA1NTR

UMA1NTR Description

The UMA1NTR from ROHM Semiconductor is a pre-biased dual PNP bipolar transistor array in a compact UMT5 surface-mount package. Designed for high-frequency switching and amplification, it features a 250MHz transition frequency, 50V collector-emitter breakdown voltage, and a low Vce saturation of 300mV (at 500µA Ib, 10mA Ic), ensuring efficient power handling. With integrated 22kΩ base (R1) and emitter-base (R2) resistors, it simplifies circuit design by eliminating external biasing components. The device is RoHS3 compliant, REACH unaffected, and rated for 150mW max power dissipation, making it suitable for modern, miniaturized electronics.

UMA1NTR Features

• Pre-biased design: Integrated 22kΩ resistors reduce external part count and PCB space.
• High-speed performance: 250MHz transition frequency ideal for switching applications.
• Low saturation voltage: 300mV @ 10mA Ic enhances energy efficiency.
• Robust voltage handling: 50V Vce(max) ensures reliability in diverse circuits.
• Compact UMT5 package: Surface-mount form factor (Tape & Reel) for automated assembly.
• Wide operating range: DC current gain (hFE) of 56 @ 5mA, 5V for stable amplification.
• Low leakage current: 500nA collector cutoff (max) minimizes power loss.

UMA1NTR Applications

• Signal amplification in audio/video equipment and sensor interfaces.
• High-speed switching for load drivers, relays, and LED control.
• Portable electronics (e.g., wearables, IoT devices) due to low power and small footprint.
• Automotive modules like lighting systems, where reliability and efficiency are critical.
• Industrial automation for logic level shifting and interface circuits.

Conclusion of UMA1NTR

The UMA1NTR stands out for its integration, speed, and efficiency, offering a streamlined solution for designers needing compact, pre-biased transistor arrays. Its combination of high-frequency capability, low saturation, and robust voltage tolerance makes it superior to generic discrete transistors, particularly in space-constrained or power-sensitive applications. ROHM’s quality assurance (MSL 1, RoHS3) further ensures long-term reliability in demanding environments.
