1N4935GPHE3/73

Overview

The Vishay General Semiconductor 1N4935GPHE3/73 is a glass-passivated fast switching plastic rectifier diode. It features a Superectifier structure for high reliability and operates with a maximum average forward rectified current of 1.0 A at 75 °C. The device provides a maximum repetitive peak reverse voltage of 200 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 maximum reverse recovery time of 200 ns. The junction temperature range extends from -65 to +175 °C.

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm compliance status and packaging details. Confirm that the component meets the required environmental standards for the intended application. Ensure that the lead length and mounting style align with the design specifications before finalizing procurement orders.

Selection Notes

Select this component when a fast recovery rectifier with a 200 V rating is required for general purpose or telecommunication applications. Consider the thermal resistance and derating curves if operating near the maximum junction temperature limits. Verify compatibility with existing circuit designs requiring low leakage current and high surge capability within the DO-41 package constraints.

Part Context

This part belongs to the 1N493xGP series of glass-passivated fast switching plastic rectifiers manufactured by Vishay General Semiconductor. The series includes variants with different reverse voltage ratings ranging from 50 V to 600 V. These components utilize a Superectifier structure designed for high reliability and are housed in the standard DO-41 molded epoxy package.

Replacement Considerations

Direct substitutes within the same Vishay family include 1N4933GP, 1N4934GP, 1N4936GP, and 1N4937GP, provided the reverse voltage requirements match the circuit design. Cross-manufacturer replacements must be verified for identical electrical parameters, package dimensions, and thermal characteristics.
