2SC3649S-TD-H

Single Bipolar Transistors Overview

The onsemi 2SC3649S-TD-H is a discontinued NPN bipolar junction transistor (BJT) designed for surface-mount applications. It features a collector-emitter breakdown voltage of 160 V and a maximum continuous collector current of 1.5 A. The device operates with a transition frequency of 120 MHz and dissipates up to 500 mW of power. It utilizes the PCP package, equivalent to TO-243AA, and supports a junction temperature of 150°C. Key electrical characteristics include a DC current gain of 200 at 100 mA and 5 V, with a saturation voltage of 450 mV at 500 mA.

Single Bipolar Transistors Procurement Notes

This component is officially obsolete and no longer manufactured by onsemi. Procurement should focus on verified surplus stock or authorized distributors holding remaining inventory. Verify part authenticity and storage conditions carefully, as end-of-life components may have varying shelf lives. Cross-reference with the specified replacement model for availability.

Single Bipolar Transistors Selection Notes

Select this component only if legacy compatibility is required, as it is no longer in production. For new designs, consider the 2SC3649T-TD-E as a direct functional substitute from the same manufacturer. Evaluate thermal management requirements due to the 500 mW power limit and ensure the PCB layout supports the PCP package footprint.

Single Bipolar Transistors Part Context

The 2SC3649 series represents a line of NPN transistors from onsemi, commonly used in consumer electronics and industrial control systems. The 'S' suffix typically denotes specific packaging or testing variations within the product family. This particular variant was widely utilized before its discontinuation announcement in April 2021.

Single Bipolar Transistors Replacement Considerations

The 2SC3649T-TD-E is listed as an official alternative by onsemi. Verify pinout compatibility and parameter equivalence before substitution. No other cross-manufacturer equivalents are confirmed in public documentation.
