MRF5035 – MOTOROLA

The MRF5035, manufactured by Motorola, is a discrete NPN bipolar junction transistor (BJT) designed for high-frequency amplifier applications. The “MOTOROLA/99” marking indicates a date code, signifying manufacture in 1999. This device is characterized by its high transition frequency (fT), enabling operation in VHF and UHF bands. Key electrical parameters include collector-emitter breakdown voltage (VCEO), collector current (IC), and power dissipation (PD), the exact values of which are contingent upon the original Motorola datasheet specifications. The MRF5035 is typically supplied in a through-hole package, likely a TO-39 or similar configuration, facilitating heat sinking and robust mechanical mounting. The “Tubes of 20” designation specifies the standard packaging method, indicating that the transistors are shipped in antistatic tubes, each containing 20 individual units, to protect against electrostatic discharge and physical damage during handling and storage.
