To learn more about ON Semiconductor, please visit our website at
www.onsemi.com
Please note: As part of the Fairchild Semiconductor integration, some of the Fairchild orderable part numbers
will need to change in order to meet ON Semiconductor’s system requirements. Since the ON Semiconductor
product management systems do not have the ability to manage part nomenclature that utilizes an underscore
(_), the underscore (_) in the Fairchild part numbers will be changed to a dash (-). This document may contain
device numbers with an underscore (_). Please check the ON Semiconductor website to verify the updated
device numbers. The most current and up-to-date ordering information can be found at www.onsemi.com. Please
email any questions regarding the system integration to Fairchild_questions@onsemi.com.

NPN RF Transistor
This device is designed for use as RF amplifiers, oscillators and
multipliers with collector currents in the 1.0 mA to 30 mA range.
Sourced from Process 43.
Absolute Maximum Ratings* TA = 25°C unless otherwise noted
*These ratings are limiting values above which the serviceability of any semiconductor device may be impaired.
NOTES:
1) These ratings are based on a maximum junction temperature of 150 degrees C.
2) These are steady state limits. The factory should be consulted on applications involving pulsed or low duty cycle operations.

made from a dissipative (carbon filled) polycarbonate
resin. The cover tape is a multilayer film (H eat Acti vated
Adhesive in nature) primaril y composed of polyester film,
adhesive layer, sealant, and anti-static sprayed agent.
These reeled parts in standard option are shipped with
3,000 uni ts per 7" or 177cm diameter reel. The reels are
dark blue in color and is made of polystyrene plastic (anti-
static coated). Other option comes in 10,000 units per 13"
