Frequently Asked Questions
What is the maximum collector-emitter voltage and collector current for the FMG9AT148?
The FMG9AT148 supports a maximum collector-emitter voltage of 50 V and a maximum collector current of 100 mA, making it suitable for low-power signal switching and amplification tasks in circuits operating at these voltage and current levels.
How does the built-in bias resistor in FMG9AT148 simplify circuit design?
The FMG9AT148 includes a built-in bias resistor ratio of 1:1 between two NPN elements, eliminating the need for external bias resistors. This reduces PCB footprint, lowers component count, and simplifies layout—especially useful in space-constrained portable designs operating at signal levels below 50 V.
Which package does the FMG9AT148 use and how many pins does it have?
The FMG9AT148 uses the SOT23-5 (SC-74A) surface-mount package with 5 pins. This compact package measures approximately 2.9 mm × 1.6 mm, making it ideal for high-density PCB layouts where board space is at a premium in portable or miniaturized electronic designs.
Is the FMG9AT148 compliant with RoHS environmental regulations?
Yes, the FMG9AT148 is RoHS compliant and Pb-free (JESD-609 Code e1), making it suitable for use in environmentally regulated products. The component meets modern lead-free soldering requirements and is compatible with standard reflow soldering processes at typical peak temperatures of 260 °C.
