SR1202HR0G

Single Diodes Overview

The SR1202HR0G is a 12A, 20V Schottky Barrier Rectifier from the SR1202 series by Taiwan Semiconductor. It features an AEC-Q101 qualification and utilizes a DO-201AD package with pure tin-plated leads. Key electrical parameters include a maximum repetitive peak reverse voltage of 20V, a forward current rating of 12A, and a non-repetitive surge current capability of 320A at 8.3ms. The device operates within a junction temperature range of -55°C to +150°C, offering low forward voltage drop and high efficiency for power applications.

Single Diodes Feature Summary

• AEC-Q101 qualified for automotive reliability standards
• Guard ring structure provides enhanced overvoltage protection
• Low forward voltage drop minimizes power loss and improves system efficiency
• High surge current capability ensures robustness during transient phases

Single Diodes Applications

• Switching mode power supplies (SMPS)
• DC to DC converters
• Adapters

Single Diodes Procurement Notes

Verify that the specific ordering code matches the required AEC-Q101 qualification status indicated by the 'H' suffix. Confirm the package type is DO-201AD and check packing options such as tape & reel or ammo box quantities against project requirements. Ensure compliance with RoHS and halogen-free specifications per IEC 61249-2-21 before finalizing procurement.

Single Diodes Selection Notes

Select this component when automotive-grade reliability is required alongside high-efficiency rectification. The 20V rating suits low-voltage output stages in SMPS and DC-DC converters. Consider the thermal resistance values for heat dissipation planning. The DO-201AD through-hole package facilitates standard PCB mounting. Evaluate the 320A surge capability against potential inrush currents in the target circuit design.

Single Diodes Part Context

This part belongs to the SR1202–SR1204 series of 12A Schottky Barrier Rectifiers. The series offers varying reverse voltage ratings from 20V to 40V. The 'H' suffix specifically denotes AEC-Q101 qualification, distinguishing it from standard industrial versions. All variants share the same physical DO-201AD package and general electrical characteristics except for the breakdown voltage.

Single Diodes Replacement Considerations

Direct substitutes within the same series include SR1203HR0G (30V) and SR1204HR0G (40V) if higher voltage ratings are acceptable. Non-qualified equivalents like SR1202R0G lack the automotive certification but share identical electrical specs. Verify pinout compatibility and thermal performance when cross-referencing with other manufacturers' DO-201AD Schottky diodes.
