TIP122FP and TIP127FP are STMicroelectronics preferred sales type silicon power Darlington transistors in a monolithic Darlington configuration mounted in a Jedec TO-220FP fully molded isolated package.
The TIP122FP (NPN) and TIP127FP (PNP) are complementary silicon Darlington power transistors offered in a fully insulated TO‑220FP molded package. They are intended for linear and switching power applications and feature three leads for external heatsink attachment.
Key specifications include a collector‑emitter voltage of 100 V, collector current up to 5 A (peak 8 A), total power dissipation of 29 W, and thermal resistances of 4.3 °C/W (junction‑to‑case) and 62.5 °C/W (junction‑to‑ambient). Mechanical dimensions of the TO‑220FP package are listed, and storage temperature ranges from –65 °C to 150 °C.
