Microchip Technology APT2X101D30J

Overview

APT2X101D30J from Microsemi is an ultrafast soft recovery rectifier diode in a dual-die SOT-227 (ISOTOP®) package, rated for 300 V DC reverse voltage and 100 A average forward current at TC = 115°C with 0.5 duty cycle. It delivers low forward voltage (1.4 V typ. at 100 A), soft reverse recovery (trr = 36 ns typ. at 100 A, −200 A/μs, 25°C), and low leakage (<1 μA at rated VR). It serves as an anti-parallel or freewheeling diode in high-frequency motor controllers and industrial inverters.

For engineers reviewing the APT2X101D30J datasheet, APT2X101D30J pinout, APT2X101D30J application, or APT2X101D30J equivalent, key selection criteria include soft recovery behavior under high di/dt, thermal resistance (0.42 °C/W junction-to-case), dual-anode/dual-cathode terminal configuration, and compatibility with high-power switching topologies requiring low noise and minimal snubber loss.

Technical Context

This device integrates two independent 300 V, 100 A ultrafast diode dies in a single SOT-227 metal package with isolated terminals - Anode 1, Anode 2, Cathode 1, Cathode 2 - enabling parallel or anti-parallel configurations without external interconnects. Its soft recovery minimizes voltage overshoot and EMI during commutation in IGBT-based inverters.

Designed for operation up to 150°C junction temperature, it maintains low Qrr (36 nC typ. at 100 A, −200 A/μs, 25°C) and low IRM (<1 μA at 300 V, 25°C), supporting high-efficiency, high-density power conversion where thermal management and switching losses are critical.

FAQ

What is the maximum junction temperature rating for APT2X101D30J?

The APT2X101D30J has a specified operating junction temperature range of −55°C to +150°C. This wide range supports deployment in harsh industrial environments such as enclosed motor drives and outdoor UPS cabinets. The device maintains stable electrical parameters-including VF, trr, and IRM-across this full range, as confirmed in the 053-4057 Rev C datasheet curves. Derating of IF(AV) begins above TC = 115°C per the thermal curve in Figure 7.

Does APT2X101D30J support anti-parallel configuration with IGBTs?

Yes, APT2X101D30J is explicitly designed for anti-parallel use with IGBTs in inverter legs. Its four isolated terminals (Anode 1, Anode 2, Cathode 1, Cathode 2) allow direct mounting across individual IGBT switches without shared current paths. The soft recovery characteristic minimizes voltage overshoot during IGBT turn-off, reducing stress and enabling reliable operation in 10–20 kHz motor drives.

What is the reverse recovery charge (Qrr) of APT2X101D30J under typical operating conditions?

The APT2X101D30J exhibits a typical reverse recovery charge (Qrr) of 36 nC when tested at IF = 100 A, diF/dt = −200 A/μs, VR = 200 V, and TC = 25°C. At higher junction temperatures (125°C), Qrr increases to 120 nC under the same conditions. This low, well-characterized Qrr enables predictable snubber design and reduced turn-off losses in high-frequency switching applications.

Can APT2X101D30J be paralleled for higher current handling?

Yes, APT2X101D30J supports parallel operation using its dual-die structure: Anode 1 + Cathode 1 and Anode 2 + Cathode 2 can be independently paralleled to achieve up to 200 A total average forward current. Thermal symmetry and matched VF characteristics between dies ensure balanced current sharing. Proper mounting torque (29.2 lb·in) and uniform heatsink contact are required to maintain thermal equilibrium.

Is APT2X101D30J UL Recognized?

Yes, APT2X101D30J carries UL Recognition under file #E145592, confirming compliance with UL 60747-1 for discrete semiconductors. This recognition validates its safety performance in end-equipment requiring regulatory approval, including industrial motor drives and uninterruptible power supplies. The SOT-227 package construction and internal dielectric isolation meet mandated creepage and clearance requirements.
