STTH1212G-TR

Single Diodes Overview

The STTH1212G-TR is an ultrafast recovery diode from the STTH1212 series, manufactured by STMicroelectronics. It features a peak reverse repetitive voltage (Vrrm) of 1200 V and a maximum continuous forward current (If) of 12 A. The device exhibits a peak reverse recovery time (trr) of 100 ns and a maximum forward voltage (Vf) of 2.2 V. It operates within a junction temperature range of -65°C to 175°C and supports a peak non-repetitive forward surge current (Ifsm) of 100 A. Packaged in D2PAK for surface mount installation, it offers low leakage current and intrinsic ruggedness.

Single Diodes Procurement Notes

Verify the specific suffix 'G-TR' against official documentation to confirm tape and reel packaging and RoHS compliance status. Ensure the ordering part number matches the exact electrical ratings required for your circuit design. Cross-reference with the manufacturer's latest datasheet to validate active status and any potential obsolescence notices before finalizing procurement plans.

Single Diodes Selection Notes

Select this component for heavy-duty applications requiring high reverse voltage and fast recovery times. The TO-220FPAC or D2PAK packages provide suitable insulation and thermal management. Consider the low leakage current advantage for mission-critical systems where thermal stability is paramount. Evaluate the 12A current rating against peak load requirements to ensure adequate margin.

Single Diodes Part Context

This device belongs to the STTH1212 series of ultrafast diodes designed for industrial and automotive-grade reliability. It shares core performance traits with other members like the STTH812G but differs in current handling capabilities. The series emphasizes ruggedness and reproducible characteristics for demanding power electronics environments.

Single Diodes Replacement Considerations

Check for direct substitutes within the STTH1212 family or equivalent ultrafast diodes from other manufacturers offering matching 1200V/12A ratings. Verify pinout compatibility and package dimensions if replacing in existing PCB layouts.
