1N1202A

Single Diodes Overview

The GeneSiC Semiconductor 1N1202A is a silicon standard recovery diode housed in a DO-4 (DO-203AA) stud package. It features a repetitive peak reverse voltage of 200 V and supports a continuous forward current of 12 A. The device operates within a junction temperature range of -55 °C to 150 °C and includes high surge capability with a non-repetitive forward current rating of 200 A. It exhibits a typical forward voltage of 1.1 V at 12 A and maintains a thermal resistance from junction to case of 2.00 °C/W.

Single Diodes Feature Summary

• High surge capability for handling transient current loads
• Not sensitive to electrostatic discharge
• Standard polarity configuration with the stud serving as the cathode

Single Diodes Applications

• Industrial power conversion systems
• General-purpose rectification circuits
• Power supply units requiring robust diode protection

Single Diodes Procurement Notes

Verify the specific part marking against the official datasheet to confirm the 200 V reverse voltage rating and 12 A current capacity. Ensure the procurement matches the standard polarity variant where the stud functions as the cathode, distinct from the reverse polarity option. Confirm the DO-4 package dimensions align with the mounting hardware specifications before finalizing orders.

Single Diodes Selection Notes

Select this component when a rugged silicon standard recovery diode is required for medium-voltage applications up to 200 V. The DO-4 stud package facilitates efficient heat dissipation through direct chassis mounting, making it suitable for high-power density designs. Consider the 12 A continuous current rating and 200 A surge capability to ensure adequate margin for system transients.

Single Diodes Part Context

This component belongs to the 1N1199A through 1N1206AR series of silicon standard recovery diodes. All members of this family share identical physical dimensions, thermal characteristics, and current ratings, differing primarily in their maximum repetitive peak reverse voltage ratings which range from 50 V to 600 V.

Single Diodes Replacement Considerations

Direct replacements within the same series include the 1N1199A, 1N1200A, 1N1204A, and 1N1206A, provided the voltage rating meets or exceeds the circuit requirements. Verify that any substitute maintains the DO-4 package form factor and the 12 A current carrying capacity.
