VS-1N3208

Single Diodes Overview

The VS-1N3208 is a silicon rectifier diode from Vishay Semiconductors, designed for stud mounting in the DO-5 (DO-203AB) package. It provides a maximum average forward current of 15 A at a case temperature of 150 °C and supports a repetitive peak reverse voltage range of 50 V to 600 V. The device features low thermal impedance with a junction-to-case resistance of 0.65 °C/W and operates within a junction temperature range of -65 °C to +175 °C. Maximum non-repetitive surge currents reach 239 A at 50 Hz and 250 A at 60 Hz.

Single Diodes Procurement Notes

Verify the specific part number suffix against the manufacturer datasheet to confirm electrical ratings and polarity configuration. Confirm that the ordering code matches the required voltage rating and whether the component utilizes cathode-to-case or anode-to-case connectivity. Ensure compliance with environmental standards such as RoHS if applicable to the project requirements.

Single Diodes Selection Notes

Select this component based on the required forward current capacity and reverse voltage withstand capabilities. Evaluate the thermal management strategy by considering the junction-to-case thermal resistance and the recommended mounting torque values. Verify that the operating environment allows for the specified maximum junction temperature and that the surge current demands do not exceed the rated IFSM limits.

Single Diodes Part Context

This component belongs to the VS-1N3208 Series of silicon rectifier diodes manufactured by Vishay Semiconductors. The series includes variants with different voltage ratings ranging from 50 V to 600 V, all sharing the same physical package and general performance characteristics. These devices are engineered for high-power applications requiring robust mechanical mounting and reliable long-term operation under thermal stress.

Single Diodes Replacement Considerations

Equivalent parts include the 1N3208R variant which offers anode-to-case connectivity instead of the standard cathode-to-case configuration. Other members of the VS-1N3208 series provide higher voltage ratings while maintaining identical current and thermal specifications.
