FJH1102

Single Diodes Overview

The FJH1102 is an ultra-low leakage rectifier diode manufactured by Fairchild Semiconductor, now part of onsemi. It is housed in a DO-35 glass axial package with two terminals. The device features a breakdown voltage of 30 V at 5.0 uA reverse current and a maximum working inverse voltage of 25 V. Reverse leakage is limited to 100 pA at 25 V. Forward voltage ranges from 500 mV to 600 mV at 1.0 uA, increasing to 1.10 V at 10 mA. It supports a DC forward current of 150 mA and operates up to a junction temperature of 175 °C.

Single Diodes Feature Summary

• Ultra-low reverse leakage characteristics suitable for sensitive detection circuits
• Light-sensitive construction requiring intact body coating to maintain specified leakage performance
• High thermal stability with a maximum operating junction temperature of 175 °C

Single Diodes Applications

• Precision analog signal processing
• High-impedance sensor interfaces
• Low-current rectification applications

Single Diodes Procurement Notes

Verify the manufacturer designation as Fairchild Semiconductor or onsemi, noting that onsemi acquired Fairchild's discrete semiconductor business. Confirm the component meets RoHS compliance standards as indicated in the documentation. Ensure the DO-35 package type matches the required form factor. Check for any specific ordering suffixes that might affect packaging options such as tape and reel or bulk quantities.

Single Diodes Selection Notes

Select this component when minimal reverse leakage current is critical for circuit accuracy. The low capacitance of 3.5 pF makes it suitable for high-frequency applications where parasitic effects must be minimized. Consider the light sensitivity during PCB layout; ensure the component is not exposed to direct light sources if leakage specifications are strict. Verify that the 150 mA forward current rating meets the load requirements.

Single Diodes Part Context

The FJH1102 belongs to the family of ultra-low leakage diodes designed for specialized electronic applications. Originally produced by Fairchild Semiconductor, these components are characterized by their silicon rectifier construction and glass encapsulation. The DO-35 package provides a compact solution for through-hole mounting while maintaining robust electrical isolation and thermal dissipation capabilities.

Single Diodes Replacement Considerations

Check ON Semiconductor catalogs for updated part numbers following the Fairchild integration. Verify equivalent DO-35 packages with similar leakage and voltage ratings.
