SOT23FF PNP Transistors Set Size Standards

Adding to the company's line of low-saturation, high-current SOT23FF transistors, the ZXTP25020CFF and ZXTP19020DFF PNP devices reduce their board height to less than 1 mm. Both promise to reduce component counts, increase power density, and serve as cost-effective switchers in portable applications. The SOT23FF package also forecasts improvements in thermal resistance up to 158ºC/W, providing a power rating of 0.8W from a 15 mm x 15 mm PCB area. Compared to P-channel MOSFETs with a similar footprint, the ZXTP25020CFF reduces PCB area requirements by as much as 50% by eliminating the need for a Schottky diode. In high-side switching and load or disconnect switches, the ZXTP19020DFF reduces voltage drop to 70 mV at 1A with a 20-mA base drive, or 160 mV at 2A with a 40-mA base drive. Prices for the ZXTP25020CFF and ZXTP19020DFF are $0.17 and $0.21 each/10,000, respectively. ZETEX INC., Hauppauge, NY. (631) 360-2222.
