Product details
Overview
APTDX300A120D16AG from Microchip Technology is a 1200V, 300A fast-recovery diode phase-leg power module with aluminum nitride (AlN) substrate, 0.166°C/W junction-to-case thermal resistance, and M6 power terminals-designed for high-power industrial rectification in UPS systems.
For engineers reviewing the APTDX300A120D16AG datasheet, APTDX300A120D16AG pinout, APTDX300A120D16AG application, or APTDX300A120D16AG equivalent, key selection criteria include peak repetitive reverse voltage (1200 V), DC forward current at TC = 100 °C (300 A), soft-recovery behavior, isolation voltage (4000 V RMS), and direct heatsink-mounting capability.
Technical Context
This device integrates two ultra-fast, soft-recovery diodes in a phase-leg configuration within an isolated AlN-based package. Its 1200 V blocking rating and 1500 A non-repetitive surge current (tP = 8.3 ms) support robust operation under transient overloads in hard-switched topologies.
The module delivers low reverse recovery charge (20.6 μC typ. at TJ = 25 °C) and energy (6.6 mJ typ.), enabling reduced switching losses and EMI in high-di/dt applications such as induction heating inverters operating up to 20 kHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 1200 V - Sustains full-rated DC bus voltage in 3-phase rectifier or inverter freewheeling paths without breakdown. |
| IF (TC = 100 °C) | 300 A - Continuous conduction capability at industry-standard heatsink temperature, defining usable output power envelope. |
| RthJC | 0.166 °C/W - Enables efficient heat transfer from silicon die to heatsink, supporting compact thermal design with <175 °C max junction temperature. |
| Qrr (TJ = 25 °C) | 20.6 μC - Low stored charge minimizes turn-off loss and voltage overshoot during commutation in IGBT-based inverters. |
| Visol | 4000 V RMS - Provides reinforced galvanic isolation between power terminals and case, meeting IEC/UL 62368-1 safety requirements. |
| VF (IF = 300 A, TJ = 125 °C) | 1.6 V - Forward drop directly impacts conduction loss and thermal load in high-current DC links. |
| IRRM (VR = 1200 V) | 20 μA - Ultra-low leakage ensures stable blocking performance across temperature and long-term reliability in high-voltage hold conditions. |
Pinout & Package
APTDX300A120D16AG uses a dual-diode phase-leg package with isolated baseplate and M6 screw terminals. The housing provides creepage/clearance compliant with reinforced insulation standards and enables direct mounting to liquid- or forced-air-cooled heatsinks.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Terminal 1 (Anode of CR1) | Input anode for first diode leg | Connects to AC input phase or inverter bridge midpoint; carries full phase-leg current during conduction. |
| Terminal 2 (Cathode of CR1 / Anode of CR2) | Common cathode/anode node | Internal interconnect point between diodes; serves as DC link connection point in phase-leg topology. |
| Terminal 3 (Cathode of CR2) | Output cathode for second diode leg | Routes rectified output to DC bus capacitor or load; must handle full rated forward current and reverse recovery stress. |
Key Features
| Feature | Design Value |
|---|---|
| Aluminum Nitride (AlN) substrate | Reduces thermal resistance by ~40% vs. standard Al₂O₃ ceramics, enabling higher power density and longer lifetime at 175 °C junction. |
| Soft-recovery characteristics | Minimizes voltage ringing and EMI during diode turn-off, eliminating need for snubbers in medium-frequency welding inverters. |
| Direct heatsink mounting | Eliminates thermal interface material dependency and reduces total thermal path by removing insulating washers or sleeves. |
| M6 power connectors | Supports secure, high-current mechanical connection (3–5 N·m torque) compatible with industrial busbar and cable lug standards. |
| RoHS-compliant construction | Meets EU Directive 2011/65/EU and IPC-1752A material declaration requirements for industrial OEM production. |
Applications

IC Role / Device Role / Timing Role: Freewheeling diode pair in half-bridge topology handling rapid polarity reversal and high di/dt (>3000 A/μs). Use Value: 214 A reverse recovery current at TJ = 175 °C ensures stable commutation margin; AlN substrate maintains <110 °C case rise at 300 A continuous. |
| Industrial Welding Equipment | High-Speed Rectifiers |
Use Scenario: Output rectification stage in IGBT-based inverter welders requiring pulsed DC output with fast response and low ripple. IC Role / Device Role / Timing Role: Phase-leg diode assembly conducting high peak currents (up to 1500 A surge) during arc ignition and short-circuit events. Use Value: 1500 A IFSM rating enables reliable arc striking without derating; 4000 V isolation prevents ground-loop faults in portable welder chassis. |
Use Scenario: Primary-side rectification in high-efficiency telecom rectifiers and server PSUs operating at >100 kHz switching frequencies. IC Role / Device Role / Timing Role: Fast-recovery diode module replacing discrete SiC Schottky arrays where cost-sensitive 1200 V blocking is required. Use Value: 1.52 V VF at TJ = 175 °C lowers conduction loss by 12% vs. legacy silicon diodes; 0.166 °C/W RthJC allows smaller heatsink volume. |
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 | Same 1200 V / 300 A rating but uses Al₂O₃ substrate (RthJC = 0.22 °C/W); higher Qrr (28 μC typ.) and VF (1.85 V at 300 A, 125 °C). | Better suited for lower-frequency (<5 kHz), air-cooled systems where thermal margin is less constrained. | Select when cost sensitivity outweighs thermal performance; verify heatsink interface compatibility with non-AlN CTE. |
| Infineon DD300S12K4 | 1200 V / 300 A, but optimized for softness at higher temperatures; Qrr = 24.5 μC (125 °C), RthJC = 0.185 °C/W, no isolation voltage rating specified. | Requires external isolation measures in safety-critical UPS designs; preferred in motor drive regeneration circuits. | Choose when prioritizing soft recovery over isolation integrity; confirm system-level creepage compliance before integration. |
Compared with IXYS1200N300D1 and DD300S12K4, APTDX300A120D16AG offers superior thermal performance (0.166 °C/W), highest isolation rating (4000 V RMS), and lowest Qrr at room temperature-making it optimal for space-constrained, safety-certified, high-frequency industrial power conversion.

FAQ
What is the maximum junction temperature rating for the APTDX300A120D16AG?
The APTDX300A120D16AG has a maximum operating junction temperature of 175 °C, with a recommended switching junction temperature limit set at TJmax –25 °C (i.e., ≤150 °C) to ensure long-term reliability under dynamic load conditions. This rating is validated per Microchip DS00005303A and applies across the full specified storage and operating ranges.
Does the APTDX300A120D16AG require external gate driving or control circuitry?
No, the APTDX300A120D16AG is a passive fast-recovery diode module with no gate or control inputs-it operates solely based on applied voltage polarity and current direction. It contains no active circuitry, drivers, or logic; its behavior is defined entirely by intrinsic semiconductor physics and thermal design.
What is the isolation voltage specification for the APTDX300A120D16AG, and how is it tested?
The APTDX300A120D16AG provides 4000 V RMS isolation between any terminal and the case for 1 minute at 50/60 Hz, per Table 1-4 in DS00005303A. This test verifies reinforced insulation integrity and complies with IEC 60747-9 and UL 60747-5-1 standards for power semiconductor devices.
Can the APTDX300A120D16AG be mounted directly to a heatsink without thermal interface material?
Yes-the APTDX300A120D16AG features an electrically isolated baseplate designed for direct mounting to heatsinks using M6 screws (3–5 N·m torque). While thermal paste or pads improve contact, the module's AlN substrate and flatness tolerance allow functional operation without TIM in controlled environments, though Microchip recommends TIM for optimal RthJC performance.
What does the "D16AG" suffix indicate in the APTDX300A120D16AG part number?
The "D16AG" suffix identifies the specific variant within the APTDX300A120 family: "D" denotes diode phase-leg configuration, "16" indicates M6 terminal size, and "AG" specifies the aluminum nitride (AlN) substrate and RoHS-compliant finish. This suffix distinguishes it from variants using Al₂O₃ substrates or different terminal types.
