2SA1585STPR

Single Bipolar Transistors Overview

The 2SA1585STPR is a PNP silicon epitaxial planar transistor manufactured by ROHM Semiconductor. It features a collector-emitter voltage (VCEO) of -20 V and a continuous collector current (IC) of -3 A. The device exhibits a typical collector-emitter saturation voltage (VCE(sat)) of -0.2 V at IC/IB = -2A/-0.1A. DC current gain (hFE) ranges from 120 to 390, with transition frequency (fT) up to 35 MHz. Power dissipation is rated at 0.4 W in the SPT package.

Single Bipolar Transistors Feature Summary

• Low collector-emitter saturation voltage for efficient switching performance
• High DC current gain characteristics across operating ranges
• Epitaxial planar structure ensuring reliability

Single Bipolar Transistors Applications

• General-purpose amplification circuits
• Driver applications requiring high current handling
• Complementary pairing with NPN transistors such as 2SD2150 or 2SC4115S

Single Bipolar Transistors Procurement Notes

Verify the specific ordering suffix against official ROHM documentation to confirm package type and taping specifications. Confirm that the component meets RoHS compliance requirements for your target market. Ensure design compatibility with the absolute maximum ratings provided in the datasheet before finalizing procurement plans.

Single Bipolar Transistors Selection Notes

Select this component when low saturation voltage and high current capability are required in a compact surface-mount package. Consider its complementary relationship with specific NPN counterparts for push-pull configurations. Evaluate thermal management needs given the 0.4 W power dissipation limit in the SPT housing.

Single Bipolar Transistors Part Context

This part belongs to ROHM's general-purpose bipolar junction transistor lineup designed for standard electronic equipment. It serves as a high-current alternative to lower-amperage devices within the same family. The product is intended for consumer electronics and office automation rather than automotive or medical applications.

Single Bipolar Transistors Replacement Considerations

The 2SB1424 is a pin-compatible alternative within the same ROHM portfolio. Verify electrical parameter equivalence before substitution.
