STTH1210D

Single Diodes Overview

The STTH1210D is a high-voltage ultrafast recovery diode from the STMicroelectronics STTH1210 series, designed for heavy-duty applications requiring long-term reliability. It features a peak reverse repetitive voltage (Vrrm) of 1 kV and a maximum continuous forward current (If) of 12 A. The device exhibits a peak non-repetitive forward surge current (Ifsm) of 80 A and a typical peak reverse recovery time (trr) of 48 ns. With a maximum forward voltage (Vf) of 2 V and a low peak reverse current (Ir) of 10 μA, it ensures efficient operation. Operating within a temperature range of -65°C to 175°C, it utilizes a TO-220 through-hole package.

Single Diodes Procurement Notes

Verify the specific suffix 'D' against the official datasheet to confirm pinout and insulation specifications, as variations exist within the family. Ensure the procurement channel provides genuine STMicroelectronics components with traceable lot codes. Cross-reference the RoHS compliance status and check for any recent Product Change Notifications (PCNs) that may affect material composition or manufacturing location before finalizing orders.

Single Diodes Selection Notes

Select this component when designing rectification and freewheeling circuits that require high reverse voltage blocking capabilities alongside fast switching speeds. The TO-220 package facilitates effective heat dissipation for continuous 12 A loads. Consider the 48 ns recovery time suitability for the target switching frequency. Evaluate thermal management requirements given the 175°C maximum junction temperature rating to ensure system longevity under heavy-duty conditions.

Single Diodes Part Context

The STTH1210D belongs to the STTH1210 series of ultrafast diodes, engineered for robust performance in critical power electronics. This series emphasizes low leakage and high ruggedness, distinguishing it from standard rectifiers. It serves as a specialized solution for applications where rapid turn-off and high voltage tolerance are paramount, such as in advanced motor drives and high-efficiency power conversion stages.

Single Diodes Replacement Considerations

Consult the official STMicroelectronics obsolete product list for confirmed substitutes. Verify electrical compatibility, specifically matching the 1 kV rating, 12 A current capacity, and TO-220 package form factor. Ensure any replacement maintains equivalent ultrafast recovery characteristics and thermal performance metrics.
