1N4500/TR is listed in the Single Diodes range at ChipApex. The manufacturer field lists Microchip Technology. Its product description is DIODE STANDARD DO204AH. Review the specifications below when checking this part for your BOM.
The Microchip Technology 1N4500/TR is a hermetically sealed, metallurgically bonded switching diode qualified per MIL-PRF-19500/403. It features double plug construction within a DO-35 glass package. The device supports an operating temperature range of -65°C to +175°C and withstands surge currents up to 4A for 1µS pulses. Key electrical parameters include a maximum reverse leakage current of 100nA at 75V DC, a breakdown voltage of 75V, and a forward voltage drop ranging from 0.47V to 0.60V at test currents between 250mA and 1mA.
Verify the JAN qualification level and specific ordering suffixes against the manufacturer's official datasheet LDS-0154. Confirm that the TR suffix corresponds to reel packaging requirements. Ensure compliance with lead material specifications (copper clad steel) and finish (tin/lead) for your assembly process. Cross-reference the DO-35 outline dimensions for mechanical fit.
Select this component when military-grade reliability and hermetic sealing are mandatory. The DO-35 axial leaded package suits through-hole mounting. Evaluate the 75V reverse voltage rating against circuit peak inverse voltage requirements. Consider the 175°C junction temperature capability for thermal management in enclosed or high-heat applications.
This part belongs to the 1N4500 series of switching diodes manufactured by Microchip Technology. It is designed for general-purpose and computer diode applications requiring robust performance. The device utilizes a DO-35 case outline and is distinguished by its voidless glass construction and internal metallurgical bond.
