Overview
The Vishay General Semiconductor 1N4937GPEHE3/54 is a glass passivated junction fast switching plastic rectifier. It features a Superectifier structure for high reliability and operates with a maximum repetitive peak reverse voltage of 600 V. The device supports a maximum average forward rectified current of 1.0 A at 75 °C ambient temperature and withstands a peak forward surge current of 30 A. Electrical characteristics include a maximum instantaneous forward voltage of 1.2 V, a maximum DC reverse current of 5.0 μA at rated blocking voltage, and a maximum reverse recovery time of 200 ns. The component utilizes a DO-41 (DO-204AL) molded epoxy package over a glass body.

Procurement Notes
Verify the specific ordering suffix E3/54 to confirm RoHS compliance and reel packaging format. Ensure the procurement matches the exact manufacturer part number to guarantee the correct electrical ratings and mechanical dimensions specified in the datasheet. Cross-reference the document revision date to ensure access to the most current technical specifications and regulatory compliance information.
Selection Notes
Select this component when a single configuration fast recovery rectifier is required for high-efficiency switching applications. The 600 V rating makes it suitable for higher voltage AC line rectification or DC-DC conversion stages. Verify that the operating junction temperature range of -65 to +175 °C aligns with the thermal environment of the target design.
Part Context
This part belongs to the 1N493xGP series of glass passivated fast switching plastic rectifiers from Vishay General Semiconductor. The series includes variants with different reverse voltage ratings ranging from 50 V to 600 V. All members share identical mechanical packages and similar electrical characteristics regarding forward current and surge capability, differing primarily in their breakdown voltage specifications.
Replacement Considerations
Direct substitutes within the same Vishay family include 1N4933GP through 1N4936GP if lower voltage ratings are acceptable. Other manufacturers offering equivalent DO-41 fast recovery rectifiers with 600 V and 1 A ratings may be considered, provided their reverse recovery times and forward voltage drops meet the circuit requirements.
