PTB 20101
175 Watts P-Sync, 470–860 MHz
UHF TV Power Transistor
Description
The 20101 is a class AB, NPN, common emitter UHF TV power
transistor intended for 28 Vdc operation from 470 to 860 MHz. It is
rated at 175 watts P-sync minimum output power. Ion implantation,
nitride surface passivation and gold metallization are used to ensure
excellent device reliability. 100% lot traceability is standard.
