Overview
The BA277,135 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 a low diode forward resistance of 0.7 Ω at 100 MHz. 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
Applications
- Low loss band switching in VHF television tuners
- Surface mount band-switching circuits
Procurement Notes
Verify the specific ordering suffix to confirm the tape-and-reel packaging configuration intended for automated assembly processes. Confirm that the component status remains active production data sheet status before initiating design integration. Ensure compliance with RoHS standards as indicated in the product specification documentation.
Selection Notes
Select this component for designs requiring minimal parasitic capacitance in VHF frequency ranges. The SOD523 package is suitable for space-constrained printed circuit board layouts. Evaluate thermal constraints against the specified junction-to-solder-point thermal resistance when determining placement near heat-generating components.
Part Context
This part belongs to the BA277 series of band-switching diodes produced by NXP Semiconductors. The '135' suffix typically denotes a specific reel quantity or packaging variant within the manufacturer's distribution channels. It serves as a direct successor to earlier Philips Semiconductor versions of the same functional device.
Replacement Considerations
Compatible substitutes include the BA277 from LRC, KEXIN, and Weitron Technology. Verify pinout compatibility and ensure equivalent electrical parameters such as capacitance and reverse voltage ratings are met before substitution.
