Overview
The Microchip Technology 1N458A/TR is a signal rectifier diode designed for through-hole mounting in DO-35-2 packages. It features a maximum repetitive peak reverse voltage of 150 V and an average forward current rating of 165 mA. The device exhibits a typical forward voltage drop of 1 V at rated current and a low reverse leakage current of 1 uA. Power dissipation is rated at 500 mW, with an operating temperature range spanning from -65 C to +150 C. This component is supplied in reel packaging.
Feature Summary
- Provides stable rectification performance within the specified thermal limits
- Utilizes glass axial-leaded construction for reliable through-hole integration
- Designed for applications requiring low reverse leakage characteristics
Applications
- Signal processing circuits
- Computer logic interface diodes
- General-purpose rectification tasks
Procurement Notes
Verify the specific suffix configuration against official datasheets to ensure compatibility with required environmental standards and package variations. Confirm that the reel packaging format aligns with automated assembly equipment specifications. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and traceability before finalizing procurement orders.
Selection Notes
Select this component when a standard silicon signal diode with moderate voltage blocking capability is required for through-hole designs. Ensure the circuit operates within the 165 mA forward current limit and does not exceed the 500 mW power dissipation threshold. Verify that the 150 V reverse voltage rating provides sufficient margin for the application's peak inverse voltage conditions.
Part Context
This part belongs to the broader category of discrete semiconductor diodes manufactured by Microchip Technology. It serves as a fundamental passive component in electronic assemblies, distinct from voltage reference or transient suppression devices. The DO-35 package is a standard industry form factor for small-signal axial components.
Replacement Considerations
Consult official substitution guides for equivalent signal diodes with matching voltage and current ratings. Verify pinout compatibility and thermal characteristics before integrating alternative manufacturers' parts into existing designs.
