VHF linear push-pull power MOS transistor
Features
- High power gain
- Easy power control
- Good thermal stability
- Gold metallization ensures excellent reliability. DESCRIPTION Dual push-pull silicon N-channel enhancement mode vertical D-MOS transistor, designed for broadcast transmitter applications in the VHF frequency range. The transistor is encapsulated in a 4-lead, SOT262 A1 balanced flange envelope, with two ceramic caps. The mounting flange provides the mon source connection for the transistors. PINNING
