DCX114YH-7

Overview

The DCX114YH-7 is a complementary NPN/PNP pre-biased small signal transistor manufactured by Diodes Incorporated. It integrates biasing resistors within an SOT563 package, featuring a 10 kΩ base resistor (R1) and a 47 kΩ emitter-base resistor (R2). The device supports a maximum supply voltage of ±50 V and a continuous collector current of 100 mA. Total power dissipation is rated at 150 mW, with an operating temperature range from -55°C to +150°C. The gain-bandwidth product is typically 250 MHz.

Feature Summary

• Complementary NPN and PNP transistors integrated into a single dual configuration
• Built-in biasing resistors eliminate the need for external input components
• Totally lead-free construction fully compliant with RoHS directives

Applications

• General-purpose switching applications requiring compact footprint
• Inverter circuits utilizing built-in biasing for simplified design
• Low-voltage digital logic interfacing and level shifting

Procurement Notes

Verify component authenticity through authorized distribution channels. Confirm that the marking code C14 matches the specific part number on the device surface. Ensure packaging integrity remains intact during storage to maintain moisture sensitivity level 1 compliance prior to soldering.

Selection Notes

Select this component when a complementary pair with fixed bias ratios is required in a minimal footprint. The 10k/47k resistor ratio provides specific drive characteristics suitable for standard logic levels. Verify thermal management requirements against the 833 °C/W junction-to-ambient resistance rating for the target application environment.

Part Context

This component belongs to the DCX (xxxx) H series, which offers various combinations of NPN and PNP transistors with different internal resistor values. All members of this family share the same SOT563 mechanical outline and epitaxial planar die construction, differing primarily in their internal R1 and R2 configurations.

Replacement Considerations

Direct pin-compatible substitutes within the same series include DCX114EH-7 and DCX114TH-7. These alternatives utilize the identical SOT563 package but feature different internal resistor values (22kΩ/47kΩ and 4.7kΩ/47kΩ respectively), necessitating circuit re-evaluation.
