Procurement Notes
Verify the specific ordering suffix to confirm packaging configuration. The TAP suffix indicates tape and reel packaging in ammopacks, while TR denotes standard reels. Confirm RoHS compliance status and material categorization details directly from the manufacturer datasheet before finalizing procurement specifications.
Selection Notes
Select this component for designs requiring a compact axial leaded switching diode with automotive qualification. Ensure the circuit operates within the 150 V reverse voltage limit and 200 mA average forward current constraints. Consider the thermal resistance of 350 K/W for heat dissipation planning in ambient temperature environments.
Part Context
This part belongs to Vishay's lineup of small signal switching diodes designed for general purpose applications. The DO-35 case style provides a standardized footprint for through-hole mounting. The product line emphasizes reliability through glass-passivated junction technology and robust surge current handling capabilities.
Replacement Considerations
Consult official cross-reference lists for verified substitutes. Ensure replacement parts match the DO-35 package dimensions and meet or exceed the 150 V reverse voltage rating. Verify that alternative components maintain similar reverse recovery times for high-speed switching compatibility.
FAQ
