E13007 -1 NPN Power Transistor (400V , 8A)

Description

E13007-1 – NPN Power Switching Transistor

(Used in SMPS, inverters, and high-voltage drivers)

General Description

The E13007-1 is a high-voltage, high-speed NPN bipolar junction transistor (BJT) designed specifically for switch-mode power supply applications. It combines high voltage withstand capability with fast switching performance and low saturation voltage.

It is usually found in a TO-220 package and is often used in CRT TVs, SMPS power supplies, DC-DC converters, and similar power electronics.

Typical Applications

• Switch-mode power supplies (SMPS)
• Flyback and forward converters
• CRT and TV power sections
• DC-AC inverters
• High-voltage, high-speed switching

Features

• High voltage withstand (up to 700V VCBO)
• High collector current (8A continuous)
• Fast switching speeds (~4MHz fT)
• Low saturation voltage
• Economical and widely available

Design Tips

• Needs proper heatsinking to manage power dissipation
• Drive the base with adequate current to ensure full saturation during switching
• Use snubber networks to suppress voltage spikes across collector-emitter during flyback switching
• For efficient switching, avoid using this in linear amplifier configurations
