Product details
Overview
APTDX300KK170D16AG from Microchip Technology is a 1700V, 300A fast-recovery common-cathode diode power module with aluminum nitride (AlN) substrate, 0.192°C/W junction-to-case thermal resistance, and M6 power terminals-designed for high-power rectification in UPS systems and induction heating inverters.
For engineers reviewing the APTDX300KK170D16AG datasheet, APTDX300KK170D16AG pinout, APTDX300KK170D16AG application, or APTDX300KK170D16AG equivalent, this page delivers verified electrical ratings, thermal performance data, isolation voltage compliance, soft-recovery behavior, and real-world mounting specifications to support high-reliability power stage design and thermal management validation.
Technical Context
The APTDX300KK170D16AG integrates two ultra-fast diodes in a common-cathode configuration within a single isolated package, enabling bidirectional current handling in phase-leg topologies. Its AlN substrate delivers low RthJC (0.192°C/W) and supports direct heatsink mounting without additional insulation.
It exhibits soft reverse recovery (Qrr = 37.6 μC typ. at TJ = 25°C; Err = 26.2 mJ typ.), low leakage (<25 μA at VR = 1700V), and high surge capability (IFSM = 1500 A, tP = 8.3 ms), making it suitable for hard-switched industrial converters operating up to 175°C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 1700 V - Enables use in 1200–1500 V DC-link applications with margin for voltage transients. |
| IF (DC) | 300 A at TC = 50°C - Sustains continuous conduction in high-current rectifier legs without derating. |
| VF | 2.35 V typ. at IF = 300 A, TJ = 25°C - Minimizes forward conduction loss in high-efficiency power stages. |
| Qrr | 37.6 μC typ. at TJ = 25°C - Low stored charge reduces switching losses and EMI during turn-off. |
| RthJC | 0.192 °C/W - Enables efficient heat transfer to heatsink; supports >300 W dissipation with <60°C ΔT. |
| VISOL | 4000 V RMS (1 min, 50/60 Hz) - Provides reinforced isolation between terminals and case for safety-critical systems. |
| TJ Range | –40°C to +175°C - Allows operation in harsh environments including welding and induction heating enclosures. |
Pinout & Package
APTDX300KK170D16AG uses a dual-diode common-cathode configuration in an isolated industrial power module package with M6 screw terminals. The package features aluminum nitride (AlN) substrate for superior thermal conductivity and direct heatsink-mounting capability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode 1 (A1) | First diode anode | Connects to positive side of first half-bridge leg; rated for 300 A DC and 1500 A surge. |
| Anode 2 (A2) | Second diode anode | Connects to positive side of second half-bridge leg; electrically isolated from A1 but shares cathode. |
| Cathode (K) | Common cathode node | Single low-inductance output terminal for both diodes; carries full bridge-leg return current. |
| Case / Heatsink | Isolated mechanical interface | Electrically isolated metal baseplate; rated for 4000 V RMS isolation; requires M6 mounting torque (3–5 N·m). |
Key Features

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 IXYS300KK170D16AG | Same 1700 V / 300 A rating, but uses Al2O3 substrate (RthJC = 0.22°C/W); slightly higher VF (2.45 V typ.) | Lower thermal performance limits maximum continuous power in compact heatsink designs. | Prefer APTDX300KK170D16AG when thermal headroom is constrained or AlN's 20% lower RthJC is needed. |
| Infineon DD300S17K4 | 1700 V / 300 A, but single-diode topology; requires two units for common-cathode function; higher total footprint and interconnect inductance. | Not a drop-in replacement-requires PCB redesign and doubled mounting hardware. | Select APTDX300KK170D16AG for integrated common-cathode layout, reduced system inductance, and simplified thermal management. |
Compared with IXYS300KK170D16AG and DD300S17K4, the APTDX300KK170D16AG delivers superior thermal resistance via AlN, eliminates dual-module layout complexity, and maintains soft recovery essential for EMI-sensitive industrial inverters-making it optimal for space-constrained, high-reliability rectifier modules.

FAQ
What is the maximum continuous forward current rating for APTDX300KK170D16AG?
The APTDX300KK170D16AG is rated for 300 A DC forward current at case temperature (TC) = 50°C, and 345 A at TC = 25°C per the Absolute Maximum Ratings table. Derating applies above 50°C; the device supports up to 175°C junction temperature, with forward current decreasing linearly beyond that point as shown in Figure 3-4 of the datasheet. This rating reflects real-world thermal constraints in forced-air or liquid-cooled systems.
Does APTDX300KK170D16AG support direct mounting to a heatsink without insulation?
Yes, APTDX300KK170D16AG features an electrically isolated metal baseplate rated for 4000 V RMS isolation (50/60 Hz, 1 minute), allowing direct mounting to grounded heatsinks without thermal pads or insulators. The datasheet explicitly states "direct mounting to heatsink (isolated package)" as a key benefit, and the M6 mounting torque specification (3–5 N·m) assumes direct metal-to-metal contact for optimal thermal transfer and mechanical stability.
What is the reverse recovery charge (Qrr) of APTDX300KK170D16AG at elevated temperature?
The APTDX300KK170D16AG has a reverse recovery charge (Qrr) of 93.5 μC typical at TJ = 175°C, as specified in Table 1-3 of the datasheet. This value increases significantly from 37.6 μC at 25°C due to carrier lifetime extension at high temperature-critical for predicting switching loss and snubber sizing in high-temperature industrial environments like welding or induction heating enclosures.
How does the aluminum nitride (AlN) substrate improve thermal performance in APTDX300KK170D16AG?
The aluminum nitride (AlN) substrate in APTDX300KK170D16AG provides ~170 W/m·K thermal conductivity-nearly double that of standard alumina (Al2O3)-resulting in a measured junction-to-case thermal resistance (RthJC) of just 0.192°C/W. This directly lowers steady-state junction temperature under identical power dissipation, extending lifetime and improving reliability in thermally demanding applications such as UPS and induction heating inverters.
Is APTDX300KK170D16AG RoHS compliant and lead-free?
Yes, APTDX300KK170D16AG is RoHS compliant, as confirmed in the Benefits section of the datasheet. It meets Directive 2011/65/EU requirements for restriction of hazardous substances, including lead-free terminations and packaging. No exemptions are cited, and the device is suitable for environmentally regulated industrial and commercial end equipment without special handling or documentation exceptions.
