Single Diodes Procurement Notes
Verify the specific manufacturer source, as components labeled 1N3739R are produced by multiple vendors including Powerex and International Rectifier. Confirm that the delivered unit matches the required electrical specifications and physical dimensions. Ensure the part number suffix aligns with the intended application requirements before finalizing procurement orders.
Single Diodes Selection Notes
Select this component when a 500 V reverse voltage rating is required in a DO-9 stud-mount package. Consider the standard recovery speed for non-high-frequency switching applications. Evaluate thermal management needs based on the stud mount design to ensure adequate heat dissipation during operation.
Single Diodes Part Context
This diode belongs to the 1N37xx series of axial lead or stud-mounted rectifiers. These components are widely used in medium-power electronics where reliability under high voltage stress is critical. The DO-9 package offers a compact footprint for stud mounting compared to larger flange-style packages.
Single Diodes Replacement Considerations
The 1N3738R serves as a lower voltage alternative within the same series. Verify compatibility if substituting with parts from other manufacturers such as Powerex or Vishay, ensuring identical pinout and mounting hole configurations.
