Product Overview
The MMBTA94 is a high-voltage PNP bipolar junction transistor (BJT) designed for switching and signal amplification in circuits requiring elevated voltage capability. It features a 400V collector-emitter voltage rating, 300mA maximum collector current, and 200mW power dissipation. Its high breakdown voltage makes it particularly useful in low-current high-voltage control and analog circuitry.
Packaged in a compact SOT-23 surface-mount package, the MMBTA94 supports space-efficient high-voltage designs. Typical uses include voltage level shifting, high-voltage signal switching, discrete amplifier stages, and complementary transistor circuits where a PNP device with substantially higher voltage capability is required.
