2N1711 NPN Transistor 50V/600mA 100MHz Frequency Low Saturation Voltage High Beta TO-39 Metal Package Industrial Temperature Range Reliable Switching General-Purpose Amplification

Features

NPN Polarity: As an NPN bipolar junction transistor (BJT), it uses a positive current to control the conduction between the collector and emitter. It is one of the most fundamental and widely used transistor types in electronic design, offering ease of integration into circuits.

Medium-High Voltage and Current Capability:

Collector-Emitter Voltage (V_CEO): -50 V. This indicates it can safely handle operating voltages up to 50 volts, making it suitable for

most medium-voltage circuits.

Collector Current (I_C): -600 mA. This means it can switch or amplify currents up to 600 milliamps, sufficient to drive medium-power loads such as relays, small motors, and bulbs.

Excellent Amplification Characteristics:

DC Current Gain (h_FE): Typically ranges from 50 to 150. This gain range provides effective current amplification while remaining easy to control, avoiding instability issues associated with excessively high gain.

Low Saturation Voltage: When conducting, the voltage drop between the collector and emitter is low, resulting in reduced power loss and higher efficiency, especially in switching applications.

Robust TO-39 Metal Package: Compared to modern plastic packages, the metal encapsulation offers superior heat dissipation and physical protection, enabling higher power dissipation (up to 0.8W) and reliable operation in harsher environments.

Wide Operating Temperature Range: Designed for industrial-grade applications, it can operate stably across a broad range of ambient temperatures with high reliability.

Reliable Switching Capability: Its structural design allows it to withstand load surges and shocks, making it highly durable and dependable for switching purposes.

The 2N1711 is a classic, versatile, and rugged power transistor. While it may not represent the latest technology, its proven reliability and strong driving capability ensure it remains relevant in applications prioritizing durability and thermal performance. For modern designs, engineers may opt for more contemporary, compact alternatives, but the 2N1711 continues to be important for maintaining and repairing legacy equipment

Applications

1:Power switching circuits: Such as driving relays, motors, and indicator lights.

2:Medium-power amplification circuits: Including audio amplifiers and linear voltage regulators.

3:Industrial control and automotive electronics: Where durability and temperature tolerance are critical.
