1N4148TA

Single Diodes Overview

The onsemi 1N4148TA is a small signal switching diode fabricated in planar technology and encapsulated in a hermetically sealed leaded glass DO-204AH (DO-35) package. It features a maximum repetitive reverse voltage of 100 V, an average rectified forward current of 200 mA, and a DC forward current of 300 mA. The device exhibits a maximum reverse recovery time of 4.0 ns at specified test conditions, with a total capacitance of 4.0 pF at zero bias. It operates within a junction temperature range of -55°C to +175°C and supports storage temperatures from -65°C to +200°C.

Single Diodes Procurement Notes

Verify the specific ordering suffix TA corresponds to the Ammo packing method as defined in the official onsemi documentation. Confirm that the DO-204AH package dimensions align with your PCB footprint requirements. Ensure compliance with RoHS directives if applicable to your manufacturing standards. Cross-reference the part number against the latest datasheet revision to confirm parameter stability.

Single Diodes Selection Notes

Select this component when high-speed switching performance is required in a through-hole axial lead configuration. The 100 V reverse voltage rating suits general low-voltage digital applications. Consider the thermal resistance and power dissipation limits when designing for elevated ambient temperatures or high duty cycles. Verify compatibility with existing assembly processes for bulk or ammo packed components.

Single Diodes Part Context

This part belongs to the 1N91x and 1N4x48 family of small signal diodes manufactured by onsemi. It shares electrical characteristics with other variants in the series but differs in packaging and packing methods. The DO-35 package provides a standard form factor for through-hole mounting, distinguishing it from surface mount alternatives like the SOD-80 variants within the same product line.

Single Diodes Replacement Considerations

Direct substitutes include other manufacturers' 1N4148 variants in the DO-35 package. Verify that replacement parts meet the 4.0 ns reverse recovery time and 100 V reverse voltage specifications. Check for equivalent thermal resistance and forward voltage characteristics to ensure circuit compatibility.
