Microchip Technology APT2X30DQ120J

Overview

APT2X30DQ120J from Microsemi is an ultrafast soft recovery rectifier diode in SOT-227 (ISOTOP®) package, rated for 1200 V blocking voltage and 30 A average forward current at TC = 89°C. It delivers low forward voltage (VF = 3.25 V max at IF = 30 A), ultrafast reverse recovery time (trr = 300 ns typ at IF = 30 A, diF/dt = −200 A/µs, VR = 800 V, TC = 25°C), and avalanche energy rating (EAVL = 20 mJ). It serves as anti-parallel or freewheeling diode in high-frequency inverters and motor controllers.

For engineers reviewing the APT2X30DQ120J datasheet, APT2X30DQ120J pinout, APT2X30DQ120J application, or APT2X30DQ120J equivalent, key selection criteria include soft recovery behavior, junction-to-case thermal resistance (RθJC = 1.1 °C/W), reverse leakage (IRM = 100 µA max at VR = 1200 V, TJ = 125°C), and dual-die configuration enabling parallel or anti-parallel mounting in high-power converters and UPS systems.

Technical Context

The APT2X30DQ120J integrates two independent silicon rectifier dies in a single SOT-227 metal package, supporting configurable parallel or anti-parallel connection per application need. Its soft recovery waveform minimizes EMI generation during commutation, with trr < 360 ns and Qrr < 380 nC under rated conditions.

Thermally, it features low RθJC (1.1 °C/W) and operates across −55°C to +175°C junction temperature range. Dynamic performance is characterized at multiple diF/dt rates (−200 to −1000 A/µs) and temperatures (25°C to 125°C), confirming stable soft switching behavior in hard-switched SMPS and induction heating circuits.

FAQ

What is the maximum junction temperature rating for APT2X30DQ120J?

The APT2X30DQ120J has a specified operating junction temperature range of −55°C to +175°C. This wide range supports deployment in harsh environments such as industrial motor drives and induction heating equipment. The device's thermal performance is validated up to 175°C junction, with all electrical parameters guaranteed across this full range per the 053-4221 Rev D datasheet.

Can APT2X30DQ120J be used in parallel configuration for higher current handling?

Yes, the APT2X30DQ120J supports parallel connection using its dual-die structure - Anode 1/Cathode 1 and Anode 2/Cathode 2 can be wired in parallel to achieve up to 60 A average forward current. Matching VF characteristics between dies (±5% typical) and symmetrical PCB layout are recommended to ensure current sharing. Derating guidelines apply per Microsemi's application notes for paralleled rectifiers.

Does APT2X30DQ120J have UL recognition?

Yes, the APT2X30DQ120J carries UL Recognition (file # E145592) for the SOT-227 package. This certification covers insulation, flammability, and creepage/clearance compliance per UL 60747-1 and UL 60950-1 standards, validating its suitability for safety-critical AC/DC and UPS applications requiring regulatory approval.

What is the reverse recovery charge (Qrr) of APT2X30DQ120J under typical operating conditions?

The APT2X30DQ120J exhibits Qrr = 380 nC maximum at IF = 30 A, diF/dt = −200 A/µs, VR = 800 V, and TC = 25°C. At elevated temperature (TJ = 125°C), Qrr increases to 400 nC max. These values are measured per JEDEC JESD24-10 and directly impact turn-off loss in hard-switched topologies - lower Qrr reduces switching losses and improves system efficiency.

Is APT2X30DQ120J compatible with lead-free reflow soldering processes?

Yes, the APT2X30DQ120J's SOT-227 package is qualified for lead-free reflow soldering per JEDEC J-STD-020. Its copper baseplate and metallization withstand peak temperatures up to 260°C for 20–40 seconds. Microsemi recommends following the thermal profile defined in the package specification document 053-4221 Rev D to avoid mechanical stress or bond integrity issues during assembly.
