Product Overview
Motorola ROG03 is an NPN silicon RF power driver transistor housed in a hermetically sealed TO-39 metal can. Sourced from surplus communications equipment stocks, this component serves as a driver and multiplier across VHF, CB, and mobile two-way radio transmitters, cross-referencing to Motorola OEM part number 48-134630 and industry standard ECG195A.
Key Features
- Silicon NPN bipolar junction transistor (BJT) architecture
- Industry standard TO-39 (TO-5 style) hermetic metal can package
- Three gold-plated through-hole leads
- Collector-emitter breakdown voltage (VCEO): 70 V
- Continuous collector current (IC): 1.5 A
- Total device dissipation (PD): 8 W
- Cross-references to Motorola 48-134630, 48-83750G03, and ECG195A
Applications
- Servicing driver, pre-driver, and multiplier stages in vintage VHF and land-mobile transceivers.
- Restoring output stages on classic Citizen Band (CB) and amateur radio transmitters.
- Building discrete RF amplifiers, oscillators, or transmitter projects on the maker bench.
Frequently Asked Questions
What type of transistor is the Motorola ROG03?
It is a silicon NPN bipolar junction transistor designed for RF amplification, driver, and frequency multiplier stages in radio communication circuits.
Can this part be used for vintage two-way radio repairs?
Yes. It is suited for repairing driver stages in older commercial, land-mobile, and CB transmitters that specify Motorola house part numbers 48-134630 or 48-83750G03.
What components can the ROG03 replace in legacy transmitter circuits?
The ROG03 directly replaces Motorola factory part numbers 48-134630 and 48-83750G03, and serves as a functional replacement for ECG195A and NTE195A RF driver devices.
A solid metal-can transistor from the days when RF power lived in discrete packages with real gold leads. Put it on the board, peak the coils, and get that transmitter back on the air.
