Description:

The NTE904 consists of four general purpose silicon NPN transistors on a common monolithic substrate in a 12-Lead TO5 type metal can. Two of the four transistors are connected in the Darlington configuration. The substrate is connected to a separate terminal for maximum flexibility.

The transistors of the NTE904 are well suited to a wide variety of applications in the low power systems in the DC through VHF range. They may be used as discrete transistors in conventional circuits but in addition they provide the advantages of close electrical and thermal matching inherent in integrated circuit construction.

Features:

• Matched Monolithic General Purpose Transistors
• Current Gain Matched to ±10%
• Base-Emitter Voltage Matched to ±2mV
• Operation from DC to 120MHz
• Wide Operating Current Range
• Low Noise Figure

Applications:

• General use in Signal Processing Systems in DC through VHF Range
• Custom Designed Differential Amplifiers
• Temperature Compensated Amplifiers

Note 1.

The collector of each transistor is isolated from the substrate by an integral diode. The substrate (Pin10) must be connected to the most negative point in the external circuit to maintain isolation betwen transistors and to provide for normal transistor action.
