FZT600BTA DIODES Electronic Component

The FZT600BTA from Diodes Incorporated is a surface-mount NPN Darlington transistor with exceptionally high DC current gain (hFE min of 10,000 at 500mA), enabling significant current amplification from very low base drive currents. This ultra-high gain makes it an excellent choice for space-constrained designs where driving relays, solenoids, lamps, or motors directly from low-power logic circuits or sensor outputs without additional driver stages is required. With a 140V collector-emitter breakdown voltage and 2A continuous collector current, it handles moderate power loads in industrial automation, audio amplification, and consumer electronics. Housed in a thermally efficient SOT-223 package, it dissipates up to 2W while occupying minimal PCB area, ideal for applications where board real estate is at a premium. The 250MHz transition frequency also supports fast switching circuits. Operating from -55°C to +150°C, this RoHS-compliant Darlington pair simplifies high-gain switching and amplification designs by reducing component count and total solution cost in voltage regulators, power management, and signal interface applications.
