DRA9124T0L

Overview

The DRA9124T0L is a PNP pre-biased transistor manufactured by Panasonic Electronic Components. It integrates a single NPN transistor with two internal resistors: a base resistor (R1) of 10 kΩ and an emitter-base resistor (R2) of 10 kΩ. The device supports a maximum collector current (IC) of 100 mA and a collector-emitter breakdown voltage (VCEO) of 50 V. Key electrical characteristics include a minimum DC current gain (hFE) of 160 at IC=10mA and VCE=-5V, and a maximum collector-emitter saturation voltage (VCE(sat)) of 300 mV at IC=-50mA and IB=-5mA. The component is rated for a maximum power dissipation of 125 mW and operates within a temperature range of -55°C to +150°C.

Feature Summary

• Integrated biasing network reduces external component count and simplifies circuit design.
• High DC current gain ensures efficient switching performance in digital applications.
• Compact SSMini3 F3 B surface-mount package facilitates high-density PCB layouts.

Applications

• General-purpose switching circuits
• Driver circuits for small loads
• Logic interface level shifting

Procurement Notes

Verify the specific ordering suffix 'T0L' against official Panasonic documentation to confirm tape-and-reel packaging specifications. Ensure the requested quantity aligns with standard reel sizes if automated assembly is required. Cross-reference the part number with authorized distributors to confirm current availability status and lead times prior to finalizing procurement plans.

Selection Notes

Select this component when a compact PNP solution with integrated base and emitter-base resistors is required. Verify that the 10 kΩ internal resistance values match the driving logic levels and desired base current requirements. Confirm that the 50 V voltage rating and 100 mA current capacity exceed the maximum operational stresses of the target application circuit.

Part Context

The DRA9124T0L belongs to Panasonic's lineup of pre-biased transistors designed for space-constrained electronics. These devices combine discrete transistor functionality with passive biasing elements to minimize board area. The SSMini3 F3 B package offers a small footprint suitable for modern consumer and industrial electronic devices requiring reliable semiconductor switching components.

Replacement Considerations

Consult official Panasonic substitution guides or equivalent manufacturer cross-reference lists for verified compatible parts. Ensure any replacement maintains identical pinout configuration, electrical ratings, and package dimensions to guarantee mechanical and functional compatibility without redesigning the host circuit board.
