UMH2N-TP

Overview

The UMH2N-TP is a dual NPN digital transistor manufactured by Micro Commercial Components (MCC). It integrates two pre-biased NPN transistors within a single SOT-363 surface-mount package. The device features a collector-emitter breakdown voltage of 50V and a continuous collector current rating of 100mA. Each internal transistor includes an integrated base resistor of 47 kOhms and an emitter resistor of 47 kOhms, resulting in a typical resistance ratio of 1.2. Key electrical specifications include a minimum DC current gain (hFE) of 68 at 5mA and 5V, a maximum saturation voltage of 300mV at specified currents, and a transition frequency of 250MHz. The component supports a maximum power dissipation of 150mW and operates within a temperature range of -55°C to +150°C.

Feature Summary

• Dual NPN configuration with integrated biasing resistors for simplified circuit design
• Compact SOT-363 surface-mount packaging suitable for space-constrained applications
• High switching speed capability indicated by 250MHz transition frequency

Applications

• General-purpose switching circuits requiring dual independent control
• Interface drivers for logic level translation
• Pre-biased transistor arrays in consumer electronics

Procurement Notes

Verify the specific ordering suffix and package variant when sourcing, as distribution channels may list different reel or cut-tape options. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Check for any recent Product Change Notifications (PCNs) regarding assembly sites or material updates to ensure supply chain consistency and regulatory adherence for your target market.

Selection Notes

Select the UMH2N-TP when a dual NPN solution with fixed 47kOhm base and emitter resistances is required. Ensure the 50V Vceo and 100mA Ic ratings exceed your circuit's maximum operating conditions. Compare against other UMH2 series variants if different resistance ratios or hFE gains are needed for specific biasing requirements.
