Overview
The Microchip Technology 1N457A is a JEDEC registered switching diode qualified per MIL-PRF-19500/193. It features a hermetically sealed, metallurgically bonded double-plug DO-35 package. Key electrical parameters include a maximum average DC output current of 150 mA and a steady-state power dissipation of 500 mW. The device supports a working peak reverse voltage of 60 V and a maximum reverse voltage of 70 V. Forward voltage is limited to 1.0 V at 100 mA, with low leakage currents specified across operating temperatures.
Feature Summary
- Metallurgically bonded construction within a hermetically sealed glass package for reliability
- Double-plug DO-35 axial leaded design optimized for high-density mounting
- JAN qualification available in accordance with MIL-PRF-19500/193 standards
Applications
- RS-232 and RS-422 interface networks
- Ethernet 10 Base T links
- Switching core drivers
- Local area networks
- Computer systems
Procurement Notes
Verify the specific suffix configuration when ordering, as JAN level and commercial grade variants differ in RoHS compliance status. Confirm that the required version matches the intended environmental qualification. Consult the manufacturer for tape and reel availability, as standard packaging may vary by production run. Ensure the selected part number aligns with the necessary military or commercial specifications for the target application.
Selection Notes
Select this component for applications requiring fast switching speeds and low capacitance in high-frequency data lines. The 60 V rating suits moderate voltage signal processing tasks. Consider the -55°C to +150°C junction temperature range for demanding environments. Verify thermal derating requirements if operating near the maximum temperature limit. Choose JAN versions for strict military reliability standards.
Part Context
This device belongs to the 1N457A through 1N459A series of small-signal switching diodes manufactured by Microchip Technology. The series shares identical physical dimensions and general switching characteristics, differentiated primarily by their reverse voltage ratings. These components are designed for use in computer and communication circuits where rapid response times are critical.
Replacement Considerations
Direct replacements must match the DO-35 package and meet MIL-PRF-19500/193 JAN qualifications. Equivalent parts should maintain the 60 V working peak reverse voltage and 150 mA current capacity. Verify forward voltage and leakage current specifications against the original datasheet requirements.
