BUH315D Description

Short technical summary and product information.

The BUH315D from STMicroelectronics is a high voltage, fast-switching NPN power transistor featuring an integrated freewheeling diode. Manufactured using Multiepitaxial Mesa technology with a Hollow Emitter structure, it offers cost-effective high performance and enhanced switching speeds.

 

Key electrical specifications include a maximum Collector-Emitter Voltage (VCEO) of 700V and a continuous Collector Current (IC) of 6A. The device has a maximum Total Power Dissipation (Ptot) of 44W at 25°C. It also features a typical Collector-Emitter Saturation Voltage (VCE(sat)) of 1.5V and a typical DC Current Gain (hFE) of 4 at 3A.

 

Designed for applications such as horizontal deflection circuits in televisions and monitors, the BUH315D is housed in an ISOWATT218 package. It supports through-hole mounting and operates within a junction temperature range of -65°C to 150°C.

 

This transistor is suitable for high-voltage switching applications where fast switching characteristics and integrated freewheeling protection are beneficial.
