UMD2N-TP

Overview

The UMD2N-TP is a dual digital transistor from Micro Commercial Components (MCC) featuring an integrated NPN and PNP configuration within a SOT-363 surface-mount package. It incorporates built-in biasing resistors, with typical values of R1=22kΩ and R2=22KΩ for both transistors. The device supports a maximum collector-emitter voltage (VCEO) of 50V and a continuous output current (IO) of 100mA. Key electrical characteristics include a low collector-emitter saturation voltage (VO(on)) of less than 0.3V at IO=10mA and II=0.5mA, a DC current gain (GI) minimum of 56, and a transition frequency (fT) of 250MHz. Power dissipation is rated at 150mW, with an operating junction temperature range spanning -55°C to +150°C.

• Provides low collector-emitter saturation voltage for efficient switching performance.
• Housed in a compact SOT-363 surface mount package suitable for space-constrained applications.

Applications

• Inverter circuits
• High-frequency crystal oscillators
• Starters

Procurement Notes

Verify the specific ordering suffix when purchasing. The standard UMD2N-TP designation indicates a tape and reel packing type with a quantity of 3,000 units per 7-inch reel. An alternative variant, UMD2N-TPQ2, shares the same electrical specifications but may differ in packaging or manufacturing site markings. Confirm compliance requirements such as RoHS status and halogen-free status against project specifications before procurement.

Selection Notes

Select this component for designs requiring a combined NPN and PNP digital transistor pair in a minimal footprint. Ensure the application operates within the 50V supply voltage limit and 150mW power dissipation constraints. Consider the thermal resistance of 833°C/W when calculating heat dissipation on FR4 PCBs. Verify that the required input resistance matches the 22kΩ typical value provided by the datasheet.
