Product details
Overview
APTDX300KK120D16AG from Microchip Technology is a 1200V, 300A fast-recovery common-cathode diode power module with aluminum nitride (AlN) substrate, M6 power terminals, and 4000 VRMS isolation voltage-designed for high-power rectification in UPS systems and induction heating inverters.
For engineers reviewing the APTDX300KK120D16AG datasheet, APTDX300KK120D16AG pinout, APTDX300KK120D16AG application, or APTDX300KK120D16AG equivalent, key selection criteria include junction-to-case thermal resistance (0.166 °C/W), soft-recovery behavior (Qrr = 57.2 μC at TJ = 175 °C), and rated DC forward current of 300 A at TC = 100 °C.
Technical Context
This device integrates two ultra-fast recovery diodes in a common-cathode configuration within an isolated AlN-based package, enabling bidirectional high-voltage, high-current rectification without external cathode interconnection. Its soft-recovery characteristics minimize EMI during commutation in hard-switched topologies.
The module supports direct heatsink mounting via insulated baseplate and delivers low reverse leakage (≤20 μA at 1200 V) and tight thermal impedance (ZthJC < 0.041 °C/W at t = 0.002 s), critical for sustained operation up to 175 °C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 1200 V peak repetitive reverse voltage - enables use in 690 VAC three-phase bridge rectifiers with ≥2× safety margin. |
| IF (DC) | 300 A at TC = 100 °C - defines continuous conduction capability under industrial thermal conditions. |
| VF | 1.52 V typical at IF = 300 A, TJ = 175 °C - determines conduction loss (≈456 W per diode at full load). |
| Qrr | 57.2 μC at TJ = 175 °C - quantifies stored charge affecting switching loss and snubber design in IGBT-based inverters. |
| RthJC | 0.166 °C/W - specifies thermal path efficiency from junction to case, enabling accurate heatsink sizing for 300 A operation. |
| VISOL | 4000 VRMS, 1 min, 50/60 Hz - certifies galvanic isolation between terminals and baseplate for safety-compliant system integration. |
| TJ Range | –40 °C to +175 °C - supports operation in harsh environments including welding equipment and industrial motor drives. |
Pinout & Package
APTDX300KK120D16AG uses a dual-diode common-cathode configuration in a thermally optimized, electrically isolated package with M6 screw terminals. The baseplate serves as the common cathode connection and provides mechanical mounting and thermal interface to the heatsink.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode 1 (A1) | Input terminal for first diode | Accepts high-voltage AC or DC input; rated for 1200 V reverse blocking and 300 A continuous forward current. |
| Anode 2 (A2) | Input terminal for second diode | Enables independent connection to second phase or leg in dual-phase rectifier or inverter freewheeling paths. |
| Cathode (K) | Common cathode output node | Shared low-impedance return path; electrically isolated from heatsink but thermally coupled via AlN substrate. |
Key Features
| Feature | Design Value |
|---|---|
| AlN substrate | Reduces RthJC by ~35% vs. standard Al2O3, enabling higher power density and extended lifetime at 175 °C. |
| Soft-recovery characteristic | Controls di/dt during turn-off to limit voltage overshoot and EMI generation in IGBT-based converters. |
| M6 power connectors | Supports secure, low-resistance mechanical and electrical connection for >300 A busbar or cable termination. |
| Direct heatsink mounting | Eliminates need for insulating washers or thermal pads while maintaining 4000 VRMS isolation integrity. |
| Low IRRM | ≤20 μA at 1200 V ensures minimal standby losses and stable voltage hold-up in high-impedance gate drive circuits. |

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 IXDN300KK120D16 | Same 1200 V/300 A rating and common-cathode layout, but uses Al2O3 substrate (RthJC = 0.21 °C/W) and lacks 4000 VRMS isolation rating. | Requires additional insulation hardware for high-isolation systems; less suitable for direct-mount heatsink designs. | Select when cost sensitivity outweighs thermal performance and isolation compliance requirements. |
| Infineon FF300R12ME4 | 1200 V/300 A dual-diode module with integrated NTC, but rated only to 150 °C junction and uses copper baseplate (non-isolated). | Needs external isolation interface and derating above 150 °C; unsuitable for 175 °C ambient or sealed enclosure applications. | Prefer for space-constrained designs needing temperature monitoring, provided thermal environment stays ≤150 °C. |
Compared with IXDN300KK120D16 and FF300R12ME4, the APTDX300KK120D16AG uniquely combines 175 °C operation, 4000 VRMS isolation, and AlN-based thermal performance-making it optimal for high-reliability, high-temperature industrial rectification where system-level safety and thermal headroom are critical.

FAQ
What is the maximum junction temperature rating for the APTDX300KK120D16AG?
The APTDX300KK120D16AG has a maximum operating junction temperature of 175 °C, with a recommended maximum under switching conditions set at TJmax – 25 °C (i.e., 150 °C). This rating is validated across all electrical parameters in the datasheet and enables reliable operation in high-ambient industrial environments where thermal management is constrained.
Does the APTDX300KK120D16AG require external insulation when mounted directly to a heatsink?
No-the APTDX300KK120D16AG features an electrically isolated aluminum nitride (AlN) substrate and is rated for 4000 VRMS isolation between any terminal and the case. It is designed for direct mounting to grounded heatsinks without additional insulating hardware, simplifying mechanical assembly and improving thermal transfer efficiency.
What is the reverse recovery charge (Qrr) of the APTDX300KK120D16AG at elevated temperature?
The APTDX300KK120D16AG exhibits a Qrr of 57.2 μC at TJ = 175 °C, measured under standard test conditions (IF = 300 A, dI/dt = 3400 A/μs). This value is critical for calculating switching losses and designing snubber networks in high-frequency inverter applications such as induction heating.
Can the APTDX300KK120D16AG be used in parallel configurations for higher current capacity?
Yes-the APTDX300KK120D16AG supports paralleling due to its matched dynamic characteristics and low thermal resistance. However, careful attention must be paid to symmetrical busbar layout, current-sharing inductors, and thermal coupling to ensure balanced conduction. Microchip recommends using identical mounting torque (3–5 N·m on M6 terminals) and thermal interface materials across all units.
What packaging and mounting hardware is included with the APTDX300KK120D16AG?
The APTDX300KK120D16AG ships in standard industrial packaging with no included mounting hardware. It features three M6 threaded terminals (A1, A2, K) and requires M6 screws with 3–5 N·m torque for secure electrical and mechanical connection. Users must supply compatible heatsink interface material (e.g., thermal grease or phase-change pad) and grounding provisions per system safety standards.
