Diode Arrays datasheet and documents for 1N4148UBD

1N4148UBD

Diode Arrays Overview

The Microchip Technology 1N4148UBD is a high-reliability switching diode qualified per MIL-PRF-19500/116. It features a ceramic surface mount package with gold-plated terminals over nickel underplate. The device operates within a junction and storage temperature range of -65°C to +200°C, with a thermal resistance junction-to-ambient of 325°C/W. Maximum ratings include a breakdown voltage of 100 V, working peak reverse voltage of 75 V, average rectified current of 200 mA at 75°C ambient, and non-repetitive sinusoidal surge current of 2 A. Electrical characteristics specify a forward voltage of 0.8 V at 10 mA and 1.2 V at 100 mA, reverse recovery time of 5 ns, and capacitance of 4.0 pF at 0 V.

Diode Arrays Feature Summary

Ceramic bodied construction designed for military grade reliability applications.
Very low capacitance and fast switching speeds with minimal reverse recovery times.
Surface mount UB package configuration available in doubler polarity options.

Diode Arrays Applications

High frequency data lines
RS-232 & RS-422 interface networks
Ethernet 10 Base T

Computers

Diode Arrays Procurement Notes

Verify the specific qualification level (JAN, JANTX, or JANTXV) required for your application against the part nomenclature. Confirm that the doubler polarity matches the circuit design requirements. Ensure compatibility with the specified ceramic surface mount package dimensions and terminal plating specifications during integration.

Diode Arrays Selection Notes

Select this component when military-grade reliability and ceramic packaging are mandatory. The doubler polarity variant is suitable for specific signal processing topologies requiring this configuration. Consider the operating temperature range up to +200°C and the low capacitance characteristics for high-frequency performance needs.

Diode Arrays Part Context

This component belongs to the 1N4148 family of switching diodes, offering a surface mount equivalent to the popular JEDEC registered 1N4148 number. It is available in various polarities including unidirectional, common anode, common cathode, and doubler configurations across different package types such as UBC, UB2, DO-35, and DO-213AA.

Diode Arrays Replacement Considerations

Direct replacements must match the MIL-PRF-19500/116 qualification and ceramic UB package. Verify polarity compatibility, specifically the doubler configuration, when substituting with other variants from the same manufacturer's lineup.
