Single Bipolar Transistors Procurement Notes

Verify the exact suffix against official datasheets, as variations like H1TU or H2TU may exist. Confirm RoHS compliance status and check for obsolete notices, as specific variants have been marked discontinued by distributors. Ensure the TO-220F package matches your board layout requirements before ordering.

Single Bipolar Transistors Selection Notes

Select this component when a single NPN transistor with 400 V blocking capability and 4 A continuous current handling is required. The TO-220F package provides adequate heat sinking for 30 W dissipation. Compare the 4 MHz transition frequency against your circuit speed needs and ensure the 700 V collector-base voltage exceeds your peak reverse bias conditions.

Single Bipolar Transistors Part Context

This part belongs to onsemi's discrete bipolar transistor portfolio, specifically engineered for general-purpose high-voltage applications. The TO-220F form factor is standard for medium-power electronics, allowing direct heatsink attachment. It serves as a fundamental switching element in linear and switching power topologies requiring reliable NPN conduction.
