Product details
Overview
APTDF300A120D16AG from Microchip Technology is a 1200V, 300A fast-recovery diode phase-leg power module with aluminum nitride (AlN) substrate, M6 power terminals, and 4000 VRMS isolation. It delivers soft-recovery characteristics, low junction-to-case thermal resistance (0.094 °C/W), and operates up to 175 °C junction temperature-designed for high-frequency rectification in industrial UPS systems.
For engineers reviewing the APTDF300A120D16AG datasheet, APTDF300A120D16AG pinout, APTDF300A120D16AG application, or APTDF300A120D16AG equivalent, key selection criteria include reverse recovery time (210–480 ns), forward voltage (2.4–2.7 V at 300–450 A), thermal performance under switching conditions, and isolated package mounting capability.
Technical Context
The APTDF300A120D16AG integrates two ultra-fast diodes in a phase-leg configuration with symmetrical terminal layout optimized for low-inductance busbar connections. Its AlN substrate enables direct heatsink mounting while maintaining 4000 VRMS isolation between terminals and case.
Dynamic behavior is characterized by di/dt-dependent trr (210 ns at 3000 A/μs, 125 °C) and Qrr (28 μC at same condition), supporting high-frequency hard-switching topologies. Thermal impedance profile shows multi-pole transient response with Ri values down to 0.004 °C/W and τi up to 0.051 s.

Equivalent & Alternatives
The following parts are listed as comparable options for similar fast diode phase-leg applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IXYS IXYS1200N300D1 | Higher VRRM (1200 V), identical IF, but higher trr (520 ns @ 125 °C) and no AlN substrate | Limited to lower-frequency (<30 kHz) welding and UPS due to slower recovery and higher thermal resistance | Choose when cost sensitivity outweighs high-frequency efficiency needs and thermal performance is secondary |
| Infineon DD300S12H1 | Same VRRM/IF, but uses Al₂O₃ substrate (RthJC = 0.12 °C/W), higher Qrr (35 μC), and no 4000 VRMS isolation rating | Requires external isolation barriers for safety-critical applications; less suitable for space-constrained designs | Prefer when existing thermal interface materials are optimized for alumina, or when isolation certification is handled at board level |
Compared with IXYS1200N300D1 and DD300S12H1, the APTDF300A120D16AG offers superior high-frequency switching performance (210 ns trr), lower thermal resistance (0.094 vs. ≥0.12 °C/W), and integrated 4000 VRMS isolation-enabling smaller heatsinks, reduced EMI filtering, and simplified safety compliance in industrial power systems.

FAQ
What is the maximum continuous forward current rating for the APTDF300A120D16AG at 110 °C case temperature?
The APTDF300A120D16AG has a maximum continuous forward current (IF) rating of 300 A at TC = 110 °C, as specified in Table 1-1 of the DS00005302A datasheet. This rating reflects real-world thermal constraints and must be maintained with adequate heatsinking to prevent exceeding the 175 °C maximum junction temperature. Derating is required above this case temperature.
Does the APTDF300A120D16AG support direct mounting to a heatsink without additional insulation?
Yes, the APTDF300A120D16AG supports direct mounting to a heatsink without supplemental insulation due to its aluminum nitride (AlN) substrate and 4000 VRMS isolation rating between all terminals and the case. This eliminates the need for mica washers or silicone pads, simplifying mechanical assembly and improving thermal transfer efficiency in the APTDF300A120D16AG design.
What is the reverse recovery time (trr) of the APTDF300A120D16AG under high di/dt conditions?
The APTDF300A120D16AG exhibits a reverse recovery time (trr) of 210 ns when tested at IF = 300 A, VR = 800 V, di/dt = 3000 A/μs, and TJ = 125 °C (Table 1-3). This value is critical for minimizing switching losses in high-frequency inverters and confirms the device's suitability for hard-switched topologies operating above 50 kHz.
How does the junction-to-case thermal resistance (RthJC) of the APTDF300A120D16AG impact thermal design?
The APTDF300A120D16AG has a junction-to-case thermal resistance (RthJC) of 0.094 °C/W, enabling efficient heat extraction to the heatsink. This low value allows designers to achieve lower junction temperatures at given power dissipation, extending lifetime and supporting higher power density layouts. It directly informs heatsink sizing calculations in APTDF300A120D16AG-based systems.
Is the APTDF300A120D16AG RoHS compliant and what does that mean for manufacturing?
Yes, the APTDF300A120D16AG is RoHS compliant per EU Directive 2011/65/EU, meaning it contains no lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls (PBB), or polybrominated diphenyl ethers (PBDE) above threshold limits. This ensures compatibility with lead-free reflow processes and meets environmental requirements for industrial and commercial electronics manufacturing using the APTDF300A120D16AG.
