Review WESTERN ELECTRIC Type Bridge Diode Good

The Western Electric 487C Bridge Diode is a versatile and essential component in various electronic applications. This diode, manufactured by Western Electric, a renowned name in telecommunications and electronics, is known for its high-quality construction and reliability.

The 487C Bridge Diode is a rectifying device, which means it allows current to flow in one direction while blocking it in the opposite direction. In bridge configuration, it functions by conducting current in both forward and reverse directions when connected in a specific manner, forming a full-wave rectifier circuit. This configuration is particularly useful in power supplies, audio amplifiers, and other applications where AC to DC conversion is required.

This diode features a high reverse voltage rating of 1000 volts, which makes it suitable for use in high voltage circuits. The forward voltage drop is relatively low at approximately 0.6 volts, ensuring efficient energy transfer and minimizing power loss. The maximum forward current capacity is 2.5 amps, making it suitable for small to medium power applications.

The Western Electric 487C Bridge Diode is constructed with high-quality silicon material, ensuring durability and long-lasting performance. Its compact size, with a diameter of approximately 0.7 inches and a thickness of 0.2 inches, makes it ideal for use in space-constrained applications.

The diode is housed in a robust TO-56 package, which provides excellent thermal dissipation, ensuring stable operation even under high power conditions. The package also features a metal tab for easy heat sinking and improved thermal management.

The Western Electric 487C Bridge Diode is a reliable and high-performance component that is essential in various electronic applications. Its high reverse voltage rating, low forward voltage drop, and maximum forward current capacity make it a versatile solution for power supplies, audio amplifiers, and other applications requiring AC to DC conversion. Its robust construction and excellent thermal management ensure long-lasting, stable performance.

The Western Electric 487C bridge diode is an obsolete yet historically significant component in the field of electronics. Originally designed for use in telephone switching systems, this diode offers some unique features that can be beneficial in certain applications. Here are the pros and cons of buying a Western Electric 487C bridge diode:

1. Historical significance: The Western Electric 487C bridge diode holds a special place in the history of electronics, having been used extensively in telephony applications for many years.

2. High reverse voltage: With a reverse voltage rating of up to 2000V, the 487C is suitable for use in high voltage applications where standard diodes may not be adequate.

3. Low leakage current: The 487C has a very low reverse leakage current, making it an excellent choice for applications where low current flow is essential.

4. Rugged construction: The diode's rugged design and construction make it well-suited for use in harsh environments where reliability is a top priority.

5. Availability: While the 487C is no longer in production, it is still available from various suppliers and can be sourced relatively easily.

1. Obsolete technology: The Western Electric 487C bridge diode is an obsolete component, and newer technologies may offer superior performance and reliability.

2. Higher cost: Due to its obsolete status, the 487C is often more expensive than newer diodes with similar specifications.

3. Limited availability: While the 487C is still available from some suppliers, it may not be readily available in all regions or in large quantities.

4. Lack of modern packaging: The 487C is available in a relatively large package size, which may make it less suitable for modern applications where space is a premium.

5. Limited production capacity: As the 487C is no longer in production, there is a limited supply of new units available, making it a less attractive option for high-volume applications.

The Western Electric 487C bridge diode offers some unique advantages, such as high reverse voltage, low leakage current, and rugged construction. However, its obsolete status and limited availability make it a less attractive option for many modern applications. If you have a specific application that requires the features of the 487C and cannot be met by newer technologies, then it may be worth considering. Otherwise, it is recommended to explore modern alternatives that offer superior performance and reliability at a more reasonable cost.

Details:

You are buying on a Western Electric Type 487C Bridge Diode. Shipping weight is 6 ounces. It should be put to use. It measures 1/4 inches square and 7/16 tall, not counting the terminals.

It is used, but tests good with my meter.
