2SA1774EBTLQ

Single Bipolar Transistors Overview

The 2SA1774EBTLQ is a PNP general-purpose bipolar junction transistor manufactured by ROHM Semiconductor. It operates with a collector-emitter voltage of -50 V and a continuous collector current of -150 mA, supporting a maximum power dissipation of 150 mW. The device features an excellent DC current gain (hFE) ranging from 120 to 390 at -1 mA and -6 V, with a transition frequency of 140 MHz. Packaged in the SOT-416FL (EMT3F) surface-mount format, it is designed for small-signal amplification applications.

Single Bipolar Transistors Feature Summary

• Excellent hFE linearity across operating ranges
• Designed as a complementary match for specific NPN transistors including the 2SC4617EB

Single Bipolar Transistors Applications

• General purpose small signal amplifier circuits

Single Bipolar Transistors Procurement Notes

Verify the exact ordering suffix against the manufacturer's latest documentation to confirm package type and taping specifications. Confirm RoHS compliance status and REACH SVHC declarations prior to integration. Ensure that the component is used within standard electronic equipment limits and not in specific high-reliability automotive or medical applications without explicit written agreement from the manufacturer.

Single Bipolar Transistors Selection Notes

Select this component when a low-voltage PNP transistor with high current gain is required for discrete amplification stages. The SOT-416FL package provides a compact footprint suitable for space-constrained designs. Verify that the required hFE rank aligns with the circuit design margins, as the device is classified into specific gain bins during manufacturing.

Single Bipolar Transistors Part Context

This part belongs to the 2SA1774 series of general-purpose transistors produced by ROHM Semiconductor. The series includes variants such as the 2SA1774 and 2SA1576UB, all sharing similar electrical characteristics but differing in packaging formats like SOT-416 or SOT-323. These devices are intended for standard consumer electronics and office automation equipment rather than specialized industrial or automotive environments.
