UP0421400L

Overview

The UP04214 is a composite transistor from the UP0421x series, featuring two silicon NPN epitaxial planar transistors integrated into a single SSMini6-F1 package. It includes a built-in base resistor R1 of 10 kΩ and an open collector for Tr2. The device supports a maximum collector current of 100 mA and a total power dissipation of 125 mW at 25°C. Key electrical parameters include a collector-emitter voltage (VCEO) of 50 V, a forward current transfer ratio (hFE) of 80 to 120, and a transition frequency (fT) of 150 MHz. The component operates within a junction temperature range of -55°C to +125°C.

Feature Summary

• Dual-transistor integration with one built-in base resistor to reduce mounting area and assembly costs.

Applications

• Switching circuits
• Digital circuits

Procurement Notes

Verify the specific part number suffix against the manufacturer's official database to confirm availability status. The datasheet indicates this product falls under maintenance or discontinued lifecycle stages. Confirm the latest specifications directly with Panasonic Electronic Components sales representatives before finalizing procurement plans.

Selection Notes

Select the UP04214 when a design requires two NPN transistors with one pre-biased base resistor in a compact footprint. Ensure the required base resistance matches the 10 kΩ specification. Verify that the 50 V voltage rating and 100 mA current capacity meet the circuit requirements. Consider the thermal derating curve for ambient temperatures exceeding 25°C.

Part Context

This component belongs to the UP0421x series of composite transistors designed for switching and digital applications. The series consolidates multiple discrete components into a single surface-mount package to optimize board space. The UP04214 variant specifically provides one transistor with a 10 kΩ base resistor and one unconnected collector transistor.

Replacement Considerations

Consult the official Panasonic Semiconductor website for the most current replacement information. Cross-reference with other SSMini6-F1 packaged dual NPN transistors if necessary, ensuring pinout compatibility and matching electrical ratings.
