The BAW27 is a silicon epitaxial planar small signal switching diode manufactured by Vishay Semiconductors. It is housed in the DO-35 (DO-204AH) axial leaded package and features a black cathode band for identification. The device supports a repetitive peak reverse voltage of 75 V and a continuous forward current of 600 mA. Electrical characteristics include a maximum reverse recovery time of 6 ns, a typical diode capacitance of 4 pF at 1 MHz, and a breakdown voltage of 75 V. Thermal resistance from junction to ambient air is rated at 350 K/W.
Verify that the ordering suffix matches the required packaging format, such as TAP for ammopack or TR for tape and reel. Confirm the specific document revision number against the manufacturer's latest release to ensure compliance with current specifications. Validate component authenticity through authorized distribution channels before integration into production designs.
Select this component when a fast switching diode with a 75 V reverse voltage rating is required in an axial package. Ensure the design accommodates the 600 mA continuous forward current limit and the 440 mW power dissipation constraints under specified thermal conditions. Verify that the 6 ns reverse recovery time meets the circuit's frequency requirements.
This part belongs to the BAW series of small signal switching diodes produced by Vishay Semiconductors. The series utilizes silicon epitaxial planar construction to deliver reliable performance in general-purpose and high-speed switching environments. The DO-35 package provides a standard form factor suitable for through-hole mounting on printed circuit boards.
Consult official cross-reference documentation for verified substitutes. Ensure any replacement maintains equivalent voltage ratings, current capabilities, and package dimensions.
