Product details
Overview
APTDF300KK60D16AG from Microchip Technology is a 600V, 300A fast-recovery common-cathode power diode module with aluminum nitride (AlN) substrate, M6 power terminals, and 4000 VRMS isolation voltage - designed for high-frequency rectification in UPS, induction heating, and welding equipment.
For engineers reviewing the APTDF300KK60D16AG datasheet, APTDF300KK60D16AG pinout, APTDF300KK60D16AG application, or APTDF300KK60D16AG equivalent, key selection criteria include reverse recovery time (31 ns @ 25°C), junction-to-case thermal resistance (0.149 °C/W), soft-recovery behavior, and direct heatsink-mounting capability in an isolated package.
Technical Context
The APTDF300KK60D16AG integrates two ultrafast diodes in a common-cathode configuration within a single isolated AlN-based power module. Its design targets high-di/dt switching (up to 4000 A/μs) while maintaining low noise and low Qrr (220 nC @ 25°C).
Thermal performance is enabled by the AlN substrate and low RthJC, supporting continuous operation at TJ up to 175°C and case temperatures up to 125°C. Isolation voltage of 4000 VRMS enables use in grounded-heatsink topologies without additional insulation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - Maximum repetitive reverse blocking voltage per diode; supports 400 V AC line rectification with safety margin. |
| IF (DC) | 300 A @ TC = 100°C - Continuous forward current rating under real thermal conditions; defines usable conduction capacity in compact heatsink designs. |
| trr | 31 ns @ 25°C - Ultrafast reverse recovery time enabling >100 kHz switching in resonant converters and minimizing commutation losses. |
| Qrr | 220 nC @ 25°C - Low reverse recovery charge reduces turn-off losses and EMI generation during hard-switching transitions. |
| RthJC | 0.149 °C/W - Junction-to-case thermal resistance enables efficient heat transfer to external heatsink; critical for thermal derating in high-power density systems. |
| VISOL | 4000 VRMS - Isolation voltage between any terminal and case; permits direct mounting to grounded heatsinks without insulating pads. |
| VF | 2.0 V @ IF = 300 A - Forward voltage drop determines conduction loss; combined with low RthJC, enables high-efficiency operation at rated current. |
Pinout & Package
APTDF300KK60D16AG uses a dual-diode common-cathode power module package with isolated baseplate, M6 threaded terminals, and aluminum nitride (AlN) substrate. Dimensions and mechanical layout are defined in Microchip DS00005269A Figure 2-1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode 1 (A1) | Input terminal for first diode anode | Accepts high-current AC or DC input; rated for 1500 A non-repetitive surge (8.3 ms). |
| Anode 2 (A2) | Input terminal for second diode anode | Enables dual-phase or interleaved rectification; electrically independent from A1. |
| Cathode (K) | Common cathode output node | Single low-inductance output path for both diodes; optimized for high-current DC bus connection. |
| Case / Baseplate | Isolated thermal and electrical reference | Provides 4000 VRMS isolation; serves as primary thermal interface to heatsink; no electrical connection required. |
Key Features
| Feature | Design Value |
|---|---|
| Soft-recovery characteristics | Minimizes voltage overshoot and EMI during diode turn-off, reducing snubber requirements in high-di/dt applications. |
| AlN substrate | Delivers superior thermal conductivity vs. alumina, lowering junction temperature rise by ~25% under identical power dissipation. |
| M6 power connectors | Supports secure, high-current mechanical termination (3–5 N·m torque); compatible with standard industrial busbar interfaces. |
| Direct heatsink mounting | Eliminates need for insulating washers or thermal pads, simplifying assembly and improving long-term thermal reliability. |
| RoHS compliant | Meets EU Directive 2011/65/EU; suitable for environmentally regulated industrial and commercial equipment. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar fast diode module applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IXYS IXDN300KK60D16 | Same 600V/300A rating, but uses Al2O3 substrate (RthJC = 0.18 °C/W); slightly higher VF (2.15 V typ.) | Limited to lower ambient or forced-air-cooled systems due to higher thermal resistance. | Choose when cost sensitivity outweighs thermal performance; verify heatsink interface compatibility with ceramic substrate. |
| Vishay VS-300KH06 | Single-diode TO-247 package (not common-cathode); 600V/300A, but requires two devices and external interconnect for dual-anode operation. | Increases PCB layout complexity, stray inductance, and thermal management overhead versus integrated module. | Select only if modularity or replacement of legacy discrete designs is required; not drop-in for APTDF300KK60D16AG footprint. |
Compared with IXDN300KK60D16 and VS-300KH06, the APTDF300KK60D16AG delivers superior thermal performance via AlN substrate, integrated common-cathode topology, and 4000 VRMS isolation - enabling simpler, more compact, and higher-reliability designs in demanding industrial power conversion.

FAQ
What is the maximum junction temperature rating for the APTDF300KK60D16AG?
The APTDF300KK60D16AG has a maximum operating junction temperature (TJ) of 175°C, with a recommended maximum under switching conditions set at TJmax – 25°C = 150°C to ensure long-term reliability and thermal margin. This rating is confirmed in Table 1-4 of the official Microchip datasheet DS00005269A.
Does the APTDF300KK60D16AG require insulating hardware when mounted to a heatsink?
No - the APTDF300KK60D16AG features 4000 VRMS isolation between all terminals and its baseplate, enabling direct mounting to a grounded heatsink without insulating pads or washers. This simplifies thermal interface design and improves long-term thermal stability compared to non-isolated modules.
What is the reverse recovery time (trr) of the APTDF300KK60D16AG under typical operating conditions?
The APTDF300KK60D16AG exhibits a reverse recovery time of 31 ns at TJ = 25°C, IF = 300 A, VR = 400 V, and di/dt = 800 A/μs. At elevated temperature (125°C), trr increases to 140 ns under the same test conditions - a value documented in Table 1-3 of the Microchip datasheet.
Can the APTDF300KK60D16AG be used in parallel configurations?
Yes - the APTDF300KK60D16AG supports paralleling for higher current capacity, provided symmetrical layout, matched thermal paths, and current-sharing inductors are implemented. Its soft-recovery behavior and tight parameter distribution across units improve current balance versus conventional fast diodes.
What mounting torque is specified for the M6 terminals on the APTDF300KK60D16AG?
The APTDF300KK60D16AG specifies a mounting torque of 3–5 N·m for its M6 power terminals, as stated in Table 1-4 of the Microchip datasheet. Exceeding this range risks thread damage or substrate cracking; using calibrated torque tools is recommended for production assembly.
