NE58219-T1-A

Overview

The CEL NE58219-T1-A is an NPN silicon epitaxial transistor housed in a 3-pin Ultra Super Mini Mold package measuring 1.6 mm by 0.8 mm. Designed for low supply voltage applications, it targets UHF oscillator and mixer circuits. Key electrical specifications include a maximum collector-to-base voltage of 20 V, a collector-to-emitter voltage of 12 V, and a continuous collector current rating of 60 mA. The device features a typical gain-bandwidth product (fT) of 5.0 GHz at VCE = 5 V and IC = 5 mA, with a typical feedback capacitance (Cre) of 0.9 pF. It supports a total power dissipation of 100 mW and operates within a junction temperature range up to 125 °C.

Feature Summary

• High transition frequency suitable for UHF oscillator and mixer applications
• Ultra compact surface mount packaging for high-density assembly
• Low feedback capacitance for improved RF performance

Applications

• UHF Oscillator circuits
• Mixer circuits
• High density surface mount electronic assemblies

Procurement Notes

Verify the component marking code '77' on the physical device to confirm authenticity against the specified FB rank classification. Ensure the ordering suffix matches the required packing style, such as embossed tape or reel quantities, when sourcing from authorized distributors.

Selection Notes

Select this component for designs requiring a small form factor NPN transistor operating at UHF frequencies. Consider the 12 V collector-to-emitter voltage limit and 60 mA current capability during biasing calculations. Verify that the PCB layout accommodates the specific 1.6 mm x 0.8 mm package dimensions.

Part Context

This part corresponds to the 2SC5004 series manufactured by Central Semiconductor (CEL). It is functionally equivalent to the NEC/NE58219 and 2SC5004 designations found in historical semiconductor documentation. The T1 suffix typically indicates the specific tape-and-reel packaging configuration provided by the manufacturer.

Replacement Considerations

Direct substitutes include the NEC NE58219 and 2SC5004 variants. When replacing, verify that the alternative component matches the 1.6 mm x 0.8 mm package footprint and meets the 5.0 GHz fT requirement for the specific UHF application.
