Product details
Overview
APTDF200KK120D16AG from Microchip Technology is a 1200V, 200A fast-recovery common-cathode diode power 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 inverters.
For engineers reviewing the APTDF200KK120D16AG datasheet, APTDF200KK120D16AG pinout, APTDF200KK120D16AG application, or APTDF200KK120D16AG equivalent, key selection criteria include reverse recovery time (210–480 ns), junction-to-case thermal resistance (0.135 °C/W), soft-recovery behavior, and direct heatsink-mounting capability in an isolated package.
Technical Context
This device integrates two ultra-fast diodes in a common-cathode configuration within a single isolated AlN-based module, enabling bidirectional high-current freewheeling paths with matched dynamic characteristics. Its soft-recovery profile minimizes voltage overshoot and EMI during commutation in hard-switched IGBT or SiC inverter legs.
The module supports continuous DC forward current up to 200 A at TC = 115 °C and handles non-repetitive surge currents of 1000 A (8.3 ms), with reverse leakage limited to 200 μA at 1200 V and junction temperature up to 175 °C-making it suitable for demanding industrial switching applications requiring robust thermal margin and low-noise turn-off.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 1200 V - Maximum repetitive blocking voltage per diode; enables use in 600–800 V DC-link systems with safety margin. |
| IF (TC = 115 °C) | 200 A - Continuous forward current rating at case temperature; defines steady-state conduction capacity in thermal-limited operation. |
| trr (TJ = 125 °C, di/dt = 2000 A/μs) | 210 ns - Ultra-fast reverse recovery time under high di/dt; reduces switching losses and voltage spikes in high-frequency inverters. |
| RthJC | 0.135 °C/W - Low junction-to-case thermal resistance due to AlN substrate; enables efficient heat transfer to external heatsink. |
| VISOL | 4000 VRMS - Isolation voltage between any terminal and case; satisfies reinforced insulation requirements for industrial safety standards. |
| Qrr (TJ = 125 °C) | 19 μC - Reverse recovery charge under high di/dt; directly impacts turn-off loss and snubber design in IGBT/SiC half-bridges. |
| VF (IF = 200 A, TJ = 125 °C) | 1.8 V - Forward voltage drop at rated current and elevated junction temperature; determines conduction loss and thermal loading. |
Pinout & Package
APTDF200KK120D16AG uses a dual-diode common-cathode configuration in an isolated ceramic-packaged module with M6 screw terminals. The package features direct heatsink mounting via insulated baseplate and includes three terminals: Anode 1 (A1), Anode 2 (A2), and Common Cathode (K).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 | Anode of Diode 1 | Connects to high-side switch node (e.g., IGBT collector) in phase-leg topology; carries forward current during positive half-cycle. |
| A2 | Anode of Diode 2 | Connects to complementary switch node (e.g., second IGBT collector); enables symmetrical freewheeling in dual-phase or bridge configurations. |
| K | Common Cathode | Shared cathode output node tied to DC-link negative rail; provides low-inductance return path for both diodes' conduction currents. |
Key Features
| Feature | Design Value |
|---|---|
| Soft-recovery characteristics | Minimizes voltage overshoot and EMI during diode turn-off, reducing snubber component stress and system-level filtering requirements. |

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 IXDN200KK120D16 | Same 1200 V/200 A rating and common-cathode configuration, but uses Al2O3 substrate (RthJC = 0.18 °C/W) and lacks 4000 VRMS isolation. | Requires external isolation barrier for safety-critical UPS/welding; less suited for space-constrained designs needing integrated isolation. | Select when cost sensitivity outweighs thermal performance and isolation requirements. |
| Vishay VS-200KH120 | Discrete dual-diode module with identical voltage/current ratings but no common-cathode integration-requires separate cathode routing and higher layout inductance. | Increases PCB area and EMI risk in high-di/dt applications; not drop-in replaceable due to different pinout and mounting scheme. | Select only when legacy board reuse mandates discrete footprint compatibility. |
Compared with IXDN200KK120D16 and VS-200KH120, the APTDF200KK120D16AG delivers superior thermal performance (0.135 vs. 0.18 °C/W), built-in 4000 VRMS isolation, and true common-cathode integration-reducing system-level complexity and improving reliability in high-power industrial inverters.

FAQ
What is the maximum junction temperature rating for the APTDF200KK120D16AG?
The APTDF200KK120D16AG has a maximum operating junction temperature (TJ) of 175 °C, with a recommended maximum under switching conditions set at TJmax – 25 °C (i.e., 150 °C) to ensure long-term reliability and thermal margin during transient overload events. This rating is confirmed in Table 1-4 of the official DS00005268A datasheet.
Does the APTDF200KK120D16AG support direct mounting to a heatsink without additional insulation?
Yes, the APTDF200KK120D16AG features an electrically isolated baseplate rated for 4000 VRMS, enabling direct mounting to a conductive heatsink without thermal interface materials or insulating hardware. This design reduces total thermal resistance and simplifies mechanical assembly while maintaining safety isolation-verified in the Thermal and Package Characteristics section of the datasheet.
What is the reverse recovery time (trr) of the APTDF200KK120D16AG under high-di/dt conditions?
The APTDF200KK120D16AG achieves a reverse recovery time of 210 ns when tested at IF = 200 A, VR = 800 V, di/dt = 2000 A/μs, and TJ = 125 °C-significantly faster than standard recovery diodes and critical for minimizing switching losses in high-frequency IGBT inverters. This value is specified in Table 1-3 of the DS00005268A datasheet.
How does the aluminum nitride (AlN) substrate improve thermal performance in the APTDF200KK120D16AG?
The aluminum nitride (AlN) substrate in the APTDF200KK120D16AG provides ~170 W/m·K thermal conductivity-nearly triple that of standard alumina ceramics-resulting in a measured junction-to-case thermal resistance of just 0.135 °C/W. This enables more efficient heat extraction and lower steady-state junction temperatures compared to Al2O3-based alternatives, as documented in Table 1-4 and Figure 3-1 of the datasheet.
Can the APTDF200KK120D16AG be used as a direct replacement for discrete TO-247 fast diodes in existing designs?
The APTDF200KK120D16AG is not a direct footprint replacement for discrete TO-247 diodes due to its module form factor, M6 screw terminals, and common-cathode configuration-but it offers functional equivalence with significant system-level advantages: reduced layout inductance, integrated isolation, and superior thermal performance. Redesign of the mechanical mounting and terminal interface is required, as outlined in the Package Outline Drawing (Figure 2-1) of DS00005268A.
