Review NAD Original And Pair Of Output Transistors Pulled

The NAD 2SB1155 and 2SD1706 transistors are essential components in various electronic applications, particularly in audio amplifiers and power supplies. These transistors are manufactured by NAD (New Acoustic Dimensions), a well-known brand renowned for producing high-quality audio components.

The NAD 2SB1155 is a NPN (Negative-Positive-Negative) silicon transistor, specifically designed as a power transistor. It comes in a TO-3 package, which allows for efficient heat dissipation, ensuring stable performance even under heavy loads. The 2SB1155 has a maximum collector current of 24 Amps and a maximum collector-emitter voltage (Vce) of 40V. Its high power handling capability makes it suitable for applications requiring significant power output.

On the other hand, the NAD 2SD1706 is a PNP (Positive-Negative-Positive) silicon transistor, also in a TO-3 package. It has a maximum collector current of 24 Amps and a maximum collector-emitter voltage of 40V, similar to its NPN counterpart. This transistor is commonly used as a switch or a voltage controller in power amplifiers, power supplies, and other electronic circuits.

Both the NAD 2SB1155 and 2SD1706 transistors exhibit excellent electrical characteristics, including high transconductance (gm), low on-resistance (Rds(on)), and high current gain (hfe). These features contribute to their ability to efficiently control and manage electrical current, ensuring precise and reliable performance in various electronic circuits.

Additionally, the NAD 2SB1155 and 2SD1706 transistors are designed to operate at relatively high temperatures, making them suitable for use in applications where thermal stability is crucial. Their robust construction and reliable performance make them popular choices for engineers and designers seeking high-quality components for their electronic projects.

In summary, the NAD 2SB1155 and 2SD1706 transistors are versatile and powerful components, offering excellent electrical characteristics and thermal stability. Their ability to handle high current and voltages, combined with their efficient heat dissipation, makes them essential components in various electronic applications, particularly those requiring power amplification or voltage control.

The NAD 2SB1155 and 2SD1706 transistors are often used in audio applications due to their high performance and reliability. Here are some pros and cons of buying these transistors:

1. High current handling capability: These transistors can handle high currents, making them suitable for use in power amplifiers and other high-power audio applications.

2. Low noise: These transistors have a low noise figure, which is important in audio applications where low noise is critical for achieving good sound quality.

3. High gain: These transistors have a high gain, which can help to reduce the number of stages required in a circuit, making the design simpler and more cost-effective.

4. Wide operating temperature range: These transistors can operate over a wide temperature range, making them suitable for use in a variety of environments.

1. Cost: These transistors are more expensive than some other types of transistors, which may make them less attractive for budget-conscious buyers.

2. Size: These transistors are larger than some other types of transistors, which may make them more difficult to integrate into compact designs.

3. Availability: These transistors may not be as readily available as some other types of transistors, which could make it more difficult to find replacements or spare parts.

In conclusion, the NAD 2SB1155 and 2SD1706 transistors offer high performance, low noise, and high gain, making them ideal for use in audio applications. However, they come with a higher cost, larger size, and potential availability issues.

If you are designing a high-performance audio system and are willing to pay a premium for superior sound quality, then these transistors could be a good choice. However, if you are working on a budget or have space constraints, you may want to consider alternative transistors that offer similar performance but at a lower cost and smaller size. Ultimately, the decision to buy these transistors depends on your specific requirements and budget.
