Overview
The 1N4937GPHE3/73 is a glass-passivated junction fast switching plastic rectifier manufactured by Vishay General Semiconductor. It features a Superectifier structure for high reliability and operates with a maximum average forward rectified current of 1.0 A at 75 °C ambient temperature. The device supports a maximum repetitive peak reverse voltage of 600 V 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 typical reverse recovery time of 200 ns. The component utilizes a DO-41 (DO-204AL) molded epoxy package over a glass body.
Feature Summary
- Features a cavity-free glass passivated junction utilizing the Superectifier structure for enhanced reliability.
- Provides fast switching capabilities designed to improve efficiency in power conversion applications.
- Offers high forward surge capability combined with low leakage current performance.
Applications
- Fast switching rectification in power supplies

Procurement Notes
Verify that the ordering suffix matches the required packaging configuration, as the datasheet specifies distinct base quantities and delivery modes for different codes. Confirm RoHS compliance status through official documentation, noting that specific suffixes denote commercial grade materials. Ensure technical validation is performed for the intended application parameters before procurement.
Selection Notes
Select this component when a fast switching rectifier with a 600 V reverse voltage rating is required. The 1.0 A average forward current rating suits moderate power applications. Verify thermal management requirements against the specified operating junction temperature range and thermal resistance values provided in the datasheet.
Part Context
This part belongs to the 1N4933GP through 1N4937GP series of fast switching plastic rectifiers. All variants share identical electrical characteristics except for the maximum repetitive peak reverse voltage, which ranges from 50 V to 600 V across the series. The GP designation indicates the use of the Superectifier structure and glass passivation technology.
Replacement Considerations
Direct substitutes within the same series include 1N4933GP, 1N4934GP, 1N4935GP, and 1N4936GP, differentiated solely by their reverse voltage ratings. Cross-brand replacements must match the 1.0 A current, 600 V reverse voltage, and DO-41 package constraints.
FAQ
What is the maximum operating junction temperature for the 1N4937GP?
The maximum operating junction temperature is 175 °C.
How is the cathode polarity identified on the component?
Polarity is indicated by a color band located at the cathode end of the device.
