2SB1238TV2Q

Single Bipolar Transistors Overview

The 2SB1238TV2Q is a PNP medium power transistor manufactured by Rohm Semiconductor. It features a collector-emitter breakdown voltage of -80V and a maximum collector current of -0.7A. The device operates with a junction temperature up to 150°C and dissipates up to 1W of power under specific mounting conditions. It utilizes an ATV through-hole package and provides a DC current gain (hFE) ranging from 120 to 390 at specified test conditions.

Single Bipolar Transistors Feature Summary

• High breakdown voltage capability of -80V for robust operation
• Medium power handling with a maximum collector current of -0.7A
• Integrated high DC current gain for efficient signal amplification

Single Bipolar Transistors Applications

• General-purpose audio visual equipment
• Office automation equipment
• Communication devices
• Electronic appliances
• Amusement devices

Single Bipolar Transistors Procurement Notes

Verify the exact ordering suffix TV2 to confirm the taping packaging specification containing 2,500 units per reel. Confirm that the ATV package designation matches the required through-hole footprint for your printed circuit board layout. Ensure the component meets the RoHS3 compliance standards as documented in the manufacturer specifications before finalizing procurement.

Single Bipolar Transistors Selection Notes

Select this component when an -80V collector-emitter breakdown voltage is required alongside a -0.7A continuous collector current capacity. The ATV package is suitable for applications requiring through-hole mounting. Verify that the hFE range of 120 to 390 aligns with the base drive requirements of your specific circuit design to ensure proper saturation or amplification performance.

Single Bipolar Transistors Part Context

This transistor serves as a complement to the 2SD1767 and 2SD1859 NPN transistors within Rohm's medium power lineup. It is designed for general-use electronic equipment rather than specialized automotive or radiation-tolerant applications. The device supports standard operating temperatures and is intended for use in consumer electronics where reliable switching and amplification are necessary.

Single Bipolar Transistors Replacement Considerations

The 2SB1189 is a pin-compatible alternative within the same datasheet offering identical electrical characteristics but utilizing an MPT3 package instead of the ATV configuration.
