BA277,115

Overview

The BA277,115 is a planar high-performance band-switching diode manufactured by NXP Semiconductors. It is housed in a small plastic SOD523 (SC-79) surface-mount package with two leads. The device features a maximum continuous reverse voltage of 35 V and a maximum continuous forward current of 100 mA. Key electrical characteristics include a low diode capacitance of 1.2 pF at 1 MHz and 6 V reverse bias, and a low diode forward resistance of 0.7 Ω at 100 MHz. The total power dissipation is rated at 715 mW at a solder point temperature of 90 °C.

Feature Summary

• Small plastic SMD package for surface mount applications
• Low diode capacitance for minimal signal loss
• Low diode forward resistance for efficient switching
• High continuous reverse voltage rating

Applications

• Low loss band switching in VHF television tuners
• Surface mount band-switching circuits

Procurement Notes

Verify the specific ordering code BA277,115 against the manufacturer's latest documentation to ensure compatibility with the required SOD523 package and marking code. Confirm that the component status remains active or qualified for production before initiating procurement processes.

Selection Notes

Select this component when designing VHF tuner circuits requiring minimal parasitic capacitance and low insertion loss. Ensure the operating junction temperature remains within the specified -65 °C to +150 °C range and that the forward current does not exceed 100 mA during peak operation.

Part Context

The BA277 is a band-switching diode designed for VHF applications. The BA277,115 designation specifically refers to the version packaged in the SOD523 (SC-79) format, distinguishing it from other packaging variants like the tape-and-reel configuration.

Replacement Considerations

Check for equivalent band-switching diodes in the SOD523 package with similar capacitance and voltage ratings. Verify pinout compatibility, as Pin 1 is the cathode and Pin 2 is the anode.
