JANTX1N4148UBCA is listed in the Diode Arrays range at ChipApex. The manufacturer field lists Microchip Technology. Its product description is DIODE ARRAY GP 75V 200MA UB. Review the specifications below when checking this part for your BOM.
The JANTX1N4148UBCA is a small signal switching diode manufactured by Microchip Technology. It features a 75V peak reverse voltage and a 200mA forward current rating. The device utilizes a 3-pin ceramic package designed for signal or computer applications. Key electrical parameters include a 5ns recovery time, 1.2V forward voltage, and 500nA reverse current. It operates within a temperature range of -65°C to +175°C.
Verify the specific JANTX grade designation against the official Microchip datasheet to ensure compliance with required performance levels. Confirm that the 3-pin ceramic package matches the mechanical constraints of the target assembly. Check for recent Product Change Notifications (PCN) issued in January 2024 regarding potential manufacturing updates.
Select this component when hermetic sealing and high-temperature operation are mandatory. The JANTX grade offers enhanced reliability compared to standard commercial variants. Ensure the circuit design accommodates the 75V reverse voltage limit and the specific thermal characteristics of the ceramic package.
This part belongs to the MIL-PRF-19500/116T qualified family of silicon switching diodes. It shares functional similarities with other 1N4148 variants but is distinguished by its military-grade JANTX qualification and robust ceramic packaging. It serves as a ruggedized alternative to standard glass-passivated diodes in harsh environments.
Publicly confirmed substitute part numbers are not available in the provided documentation.
