APT30DQ120KG

Overview

The APT30DQ120KG is a single ultra-fast soft recovery freewheeling diode manufactured by Microchip Technology. It features a maximum repetitive reverse voltage of 1200 V and a continuous forward current rating of 30 A. The device utilizes a TO-220 package with through-hole mounting. Key electrical characteristics include a maximum forward voltage of 3.06 V at rated current and a peak non-repetitive surge current capability of 150 A. It operates within a junction temperature range up to 175°C.

Feature Summary

Ultra-fast soft recovery characteristic for reduced switching losses
High thermal stability with 175°C maximum junction temperature
Robust surge current handling capability

Applications

High-frequency power supply circuits
Motor drive freewheeling applications
DC-DC converter output rectification

Procurement Notes

Verify the specific suffix 'KG' against the official Microchip datasheet to confirm pinout and packaging details, as suffixes can indicate variations in tape-and-reel or bulk packaging. Ensure the procurement channel provides valid traceability documentation. Confirm that the component status is active and not obsolete before finalizing orders.

Selection Notes

Select this component when designing circuits requiring fast recovery times to minimize reverse recovery charge losses. The 1200 V rating suits medium-voltage industrial applications. Compare the 3.06 V forward voltage drop against system efficiency requirements. Ensure the thermal management design supports the 175°C junction limit under worst-case load conditions.

Part Context

This part belongs to Microchip's APT series of discrete power diodes, specifically designed for high-efficiency switching applications. It complements other components in the same voltage class, such as the APT30DQ100BGVAO, which offers similar performance at a lower voltage rating. The series emphasizes reliability in demanding power electronics environments.
