2SD24590SL

Overview

The Panasonic 2SD24590SL is a silicon NPN epitaxial planar transistor designed for low-frequency output amplification. It features a MiniP3-F1 surface-mount package with a collector-base voltage of 150 V and a collector-emitter voltage of 150 V. The device supports a continuous collector current of 1 A and a peak collector current of 1.5 A, with a maximum collector power dissipation of 1 W at 25°C ambient temperature. Electrical characteristics include a minimum forward current transfer ratio (hFE) of 40 at 500 mA and a typical transition frequency of 90 MHz.

Feature Summary

• High collector-emitter voltage rating suitable for demanding amplification circuits
• Low collector-emitter saturation voltage to minimize power loss during conduction
• Mini Power type package enabling equipment downsizing and automated insertion

Applications

• Low-frequency output amplification
• General electronic equipment
• Household appliances

Procurement Notes

Verify the exact suffix '0SL' against official Panasonic documentation, as datasheets may list the base part number without specific ordering codes. Confirm the product lifecycle status, as this component is categorized under maintenance or discontinued types. Ensure compliance with RoHS directives and verify that the intended application falls within standard general electronics rather than specialized safety-critical systems.

Selection Notes

Select this component when a high-voltage NPN transistor is required in a compact surface-mount form factor. The MiniP3-F1 package facilitates automated manufacturing processes. Consider the thermal derating curve for applications operating above 25°C ambient temperature. Verify that the hFE rank (R or S) meets the specific gain requirements of the target circuit design.

Part Context

This component belongs to the Panasonic 2SD2459 series of silicon NPN transistors. It utilizes an epitaxial planar construction optimized for robust performance in low-frequency applications. The device is manufactured by Panasonic Electronic Components and is compliant with the EU RoHS Directive. It is distinct from other series such as the 2SD2413 or 2SD2620G which feature different voltage ratings and packages.

Replacement Considerations

Consult official Panasonic resources for verified substitute part numbers. Cross-referencing should be performed carefully to ensure matching voltage, current, and package specifications.
