1N4150-1/TR

Single Diodes Overview

The Microchip Technology 1N4150-1/TR is a hermetically sealed switching diode in a DO-35 glass package. It features a metallurgically bonded double plug construction and copper clad steel leads with tin/lead finish. The device supports an operating temperature range of -65°C to +175°C, with a maximum DC reverse voltage of 50V and forward current of 200mA. Key electrical characteristics include a maximum reverse recovery time (TRR) of 4ns at specified test conditions, a capacitance of 2.5pF at 0V, and a total power dissipation rating of 500mW.

Single Diodes Feature Summary

• Hermetically sealed glass package per MIL-PRF-19500/231
• Metallurgically bonded double plug construction
• Copper clad steel leads with tin/lead finish

Single Diodes Applications

• High reliability military applications requiring JAN, JANTX, or JANTXV qualification levels
• Fast switching circuits due to low reverse recovery time
• Harsh environment electronics utilizing wide operating temperature range

Single Diodes Procurement Notes

Verify the specific qualification level required for your application, as the component is available in JAN, JANTX, and JANTXV grades per MIL-PRF-19500/231. Confirm that the /TR suffix indicates tape and reel packaging if automated assembly is planned. Ensure lead material specifications meet mechanical stress requirements for your board layout.

Single Diodes Selection Notes

Select this component when high reliability and hermetic sealing are critical. The DO-35 outline provides a standard through-hole footprint suitable for legacy and robust designs. Consider the thermal resistance of 250°C/W and derating factor of 2 mA/°C above +75°C for thermal management planning in enclosed spaces.

Single Diodes Part Context

This part belongs to the 1N4150 series of silicon signal diodes manufactured by Microchip Technology. It is designed to replace older equivalents while meeting modern military standards. The DO-35 package is a standard axial-leaded form factor widely used in general-purpose and specialized switching applications across various industries.

Single Diodes Replacement Considerations

Direct replacements must match the DO-35 package and hermetic seal requirement. Verify that substitute parts offer comparable TRR and VBR specifications. Ensure the replacement also meets the specific MIL-PRF-19500/231 grade needed for your system's reliability targets.
