Product Overview
Built for general-purpose audio preamplifiers, signal amplifiers, and driver stages, the NTE46 NPN silicon Darlington transistor delivers a minimum DC current gain of 10,000 in a standard 3-lead TO-92 package. It pairs high input impedance with 100V collector-emitter voltage breakdown protection and 500mA continuous collector current capacity.
Key Features
- NPN silicon Darlington configuration for high-gain amplification
- 100V collector-emitter breakdown voltage (VCEO)
- 500mA continuous collector current rating
- 625mW total device dissipation
- 10,000 minimum DC current gain (hFE)
- Standard 3-lead TO-92 through-hole package
Applications
- Restoring vintage audio equipment, preamplifier circuits, and driver stages requiring high gain.
- Interfacing low-current microcontroller logic pins to relays, solenoids, or indicator lamps on maker projects.
- Servicing legacy industrial control boards originally engineered around ECG46 or SK9461 transistors.
Frequently Asked Questions
What is the pinout configuration for the NTE46 in the TO-92 package?
Facing the flat printed face with leads pointed downward, the pin arrangement from left to right is emitter (pin 1), base (pin 2), and collector (pin 3).
Can the NTE46 substitute for an ECG46 or SK9461?
Yes, the NTE46 is a direct cross-reference replacement for both ECG46 and SK9461 bipolar Darlington transistors. More pieces cost less each - the price-break table on this page shows what each quantity costs.
High gain in a TO-92 is the quiet workhorse of the analog bench. When a weak signal needs real muscle to trip a relay or drive a stage, this is the drop-in that gets the circuit talking again.
