1N4148-T26A

Single Diodes Overview

The onsemi 1N4148-T26A is a small signal switching diode housed in a DO-35 axial lead package. It features a maximum repetitive reverse voltage of 100 V and an average rectified forward current of 200 mA. The device supports a DC forward current of 300 mA and a non-repetitive peak forward surge current of 4.0 A at a pulse width of 1.0 microsecond. Electrical characteristics include a maximum reverse leakage current of 5.0 uA at 75 V, a total capacitance of 4.0 pF at 1.0 MHz, and a reverse recovery time of 4.0 ns. Operating junction temperature ranges from -55°C to +175°C.

Single Diodes Procurement Notes

Verify the specific ordering suffix T26A corresponds to the Ammo packing method as defined in the official onsemi documentation. Confirm that the DO-35 package dimensions align with JEDEC standards for your assembly process. Ensure compliance with RoHS and REACH requirements by checking the manufacturer's latest environmental declarations before finalizing procurement.

Single Diodes Selection Notes

Select this component when a fast silicon switching diode is required within a through-hole DO-35 form factor. The 100 V reverse voltage rating suits general-purpose low-voltage logic and signal processing tasks. Consider the 4.0 ns recovery time for frequencies requiring rapid transition speeds. Verify that the 200 mA average current rating meets the continuous load requirements of the target design.

Single Diodes Part Context

This part belongs to the 1N91x and 1N4x48 series of small signal diodes manufactured by onsemi. These devices utilize a silicon epitaxial planar construction designed for reliability in standard switching environments. The 1N4148 variant specifically targets applications demanding faster performance compared to older general-purpose rectifiers while maintaining compatibility with legacy through-hole layouts.

Single Diodes Replacement Considerations

The datasheet lists the 1N914 as electrically equivalent. Other variants within the same family, such as 1N4148TA or 1N4148TR, share identical electrical specifications but differ in packaging methods.
