Overview
The onsemi 1N486B_T50R is a small signal switching diode designed for through-hole mounting in the DO-35-2 axial leaded package. It features a peak reverse voltage of 225 V and a maximum forward current of 100 mA, with a peak surge current rating of 2 A. The device dissipates up to 500 mW of power and operates within a temperature range of -65 °C to +200 °C. This component is manufactured by onsemi and is currently classified as obsolete.
Feature Summary
- High peak reverse voltage capability for robust blocking performance
- Extended operating temperature range suitable for demanding environments
- Low leakage current characteristics for efficient signal handling
Applications
- General purpose signal switching circuits
- Computer logic interface applications
- Protection against reverse polarity in low-power systems
Procurement Notes
This component is officially listed as obsolete by the manufacturer. Availability is restricted to existing stock or surplus channels only. Verify authenticity and storage history carefully when sourcing from third-party distributors. No new production units are expected. Ensure compatibility with legacy designs before procurement.
Selection Notes
Select this part for legacy designs requiring a 225 V rated silicon switching diode in a DO-35 package. Consider the high junction temperature limit for thermal management. Evaluate alternative active components if long-term supply stability is required for new product development.
Part Context
The 1N486B belongs to the standard small-signal switching diode family used in digital and analog signal processing. It serves as a fundamental discrete semiconductor component for rectification and switching tasks in consumer electronics and industrial control equipment where moderate voltage isolation is necessary.
Replacement Considerations
Verify pinout compatibility with DO-35 packages. Check reverse voltage and forward current ratings against circuit requirements. Consult manufacturer cross-reference lists for direct functional equivalents.
