Overview
The 1N457AUR/TR is a small signal switching diode manufactured by Microchip Technology. It is designed for use in signal or computer applications. The device features a round-end package configuration and supports surface mount technology. Key electrical specifications include a maximum reverse voltage of 60V and a forward current rating of 150mA. The component is supplied in tape and reel packaging, indicated by the /TR suffix, facilitating automated assembly processes.
Feature Summary
- Designed for high-speed signal and computer switching applications
- Utilizes a leadless MELF-style glass encapsulation for surface mounting
- Features metallurgically bonded construction for reliability
Applications
- Signal rectification in computer systems
- High-speed switching circuits
- Clamping and protection in low-voltage logic interfaces
Procurement Notes
Verify the specific suffix /TR indicates tape and reel packaging when ordering. Confirm the manufacturer is Microchip Technology, as this part number family may have historical origins with other entities like Microsemi. Ensure the procurement documentation matches the exact part number to avoid confusion with non-reel variants or different voltage ratings within the same series.
Selection Notes
Select this component for applications requiring a compact, surface-mount switching diode with a 60V reverse voltage capability. It is suitable for environments where space constraints necessitate a MELF package. Consider the 150mA forward current limit when designing the circuit. Verify that the operating temperature range meets the system requirements, as these devices are typically rated for extended industrial temperatures.
Part Context
This component belongs to the 1N457 series of small signal switching diodes. The -1 suffix often denotes a specific variant or revision, while /TR specifies the bulk packaging format. These diodes are commonly used in digital logic circuits and data processing equipment where fast recovery times and low capacitance are critical for signal integrity.
Replacement Considerations
Check for direct equivalents such as the 1N457AUR without the reel suffix if loose components are needed. Other generic silicon switching diodes with similar 60V and 150mA ratings may serve as functional substitutes in non-critical applications, provided the package footprint and pinout compatibility are verified.
