Product details
Overview
APTDF200A120D16AG from Microchip Technology is a 1200V, 200A fast-recovery diode phase-leg power module with aluminum nitride (AlN) substrate, M6 power terminals, and 4000 VRMS isolation voltage - designed for high-frequency rectification in industrial UPS and induction heating inverters.
For engineers reviewing the APTDF200A120D16AG datasheet, APTDF200A120D16AG pinout, APTDF200A120D16AG application, or APTDF200A120D16AG 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
The APTDF200A120D16AG integrates two ultra-fast diodes in a phase-leg configuration with symmetrical terminal layout and isolated AlN-ceramic baseplate. Its soft-recovery characteristics minimize voltage overshoot and EMI during commutation with di/dt up to 2000 A/μs at 125 °C junction temperature.
Rated for 1200 V peak repetitive reverse voltage and 200 A DC forward current at TC = 115 °C, it delivers low conduction loss (VF = 2.4 V typ. @ 200 A, 25 °C) and low leakage (<200 μA @ 1200 V), enabling high-efficiency operation in hard-switched and resonant topologies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 1200 V - blocks full DC bus voltage in 1000–1200 V industrial inverters without derating |
| IF (TC = 115 °C) | 200 A - continuous forward current rating at practical heatsink temperature limit |
| trr (TJ = 125 °C, di/dt = 2000 A/μs) | 210 ns - enables >100 kHz switching in ZVS/ZCS converters with minimal turn-off loss |
| RthJC | 0.135 °C/W - allows direct thermal path to heatsink; supports >400 W dissipation at ΔT = 54 °C |
| VISOL | 4000 VRMS/1 min - meets reinforced insulation requirements for Class I equipment per IEC 60950/62368 |
| Qrr (TJ = 125 °C, di/dt = 2000 A/μs) | 19 μC - low stored charge reduces snubber losses and stress on complementary switches |
| Mounting Torque | M6 terminals: 3–5 N·m - ensures reliable mechanical and thermal contact without substrate cracking |
Pinout & Package
APTDF200A120D16AG uses a dual-diode phase-leg package with isolated AlN substrate and six M6 screw terminals: two anodes (A1, A2), two cathodes (K1, K2), and two case-isolation mounting points (M1, M2). The package is mechanically symmetrical and optimized for double-sided cooling.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 | Anode of Diode 1 | Connects to AC leg node in inverter bridge; carries full phase current during positive half-cycle |
| K1 | Cathode of Diode 1 | Connects to DC+ rail; forms freewheeling path with complementary IGBT/MOSFET |
| A2 | Anode of Diode 2 | Connects to same AC leg node as A1; parallel configuration doubles current capacity |
| K2 | Cathode of Diode 2 | Connects to DC+ rail in parallel with K1; improves current sharing and thermal distribution |
| M1 / M2 | Isolated Mounting Terminal | Electrically isolated mechanical interface for heatsink attachment; no electrical function |
Key Features

|---|---|
| Soft-recovery characteristics | Controls di/dt-dependent Irm and dV/dt overshoot - reduces EMI filter burden and gate driver stress |
| Aluminum Nitride (AlN) substrate | Thermal conductivity ≈ 170 W/m·K - cuts RthJC by ~40% vs. standard Al2O3, enabling higher power density |
| Direct heatsink mounting | No insulating washer required - eliminates interfacial thermal resistance and simplifies assembly |
| RoHS-compliant construction | Meets EU Directive 2011/65/EU - suitable for export-controlled and environmentally regulated industrial systems |
| M6 power connectors | Enables secure, low-impedance busbar connection - supports >400 A surge without terminal heating |

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 IXYS1200N200T2 | 1200 V / 200 A, but uses Al2O3 substrate (RthJC = 0.18 °C/W); no M6 terminals (uses M5) | Limited to lower di/dt (≤1000 A/μs) due to slower trr (≈320 ns) and higher Qrr (28 μC) | Acceptable where thermal margin exists and PCB layout accommodates smaller terminals; not drop-in |
| Infineon IDP200E120 | 1200 V / 200 A, SiC Schottky topology - zero Qrr, but rated only to 150 °C junction and lacks 4000 V isolation | Requires revised gate drive and snubber design; unsuitable for safety-isolated UPS or medical-grade systems | Preferred for ultra-high-frequency (>200 kHz) designs where zero recovery loss outweighs isolation and temperature trade-offs |
Compared with IXYS1200N200T2 and Infineon IDP200E120, the APTDF200A120D16AG uniquely combines 4000 V isolation, AlN thermal performance, and soft-recovery behavior - making it the only option qualified for safety-critical, high-di/dt industrial rectification without redesigning isolation barriers or thermal interfaces.

FAQ
What is the maximum junction temperature rating for the APTDF200A120D16AG?
The APTDF200A120D16AG has a maximum operating junction temperature (TJ) of 175 °C and a recommended maximum junction temperature under switching conditions (TJOP) of TJmax – 25 °C, i.e., 150 °C. This rating is validated per Table 1-4 in DS00005276A and supports sustained operation in high-ambient industrial environments when paired with appropriate heatsinking.
Does the APTDF200A120D16AG require external insulation when mounted to a heatsink?
No - the APTDF200A120D16AG features an electrically isolated aluminum nitride (AlN) substrate with 4000 VRMS isolation between all terminals and the case, enabling direct mounting to a grounded heatsink without insulating pads or washers. This eliminates interfacial thermal resistance and simplifies mechanical assembly while maintaining safety compliance.
What is the reverse recovery charge (Qrr) of the APTDF200A120D16AG at 125 °C and high di/dt?
At TJ = 125 °C and di/dt = 2000 A/μs, the APTDF200A120D16AG exhibits a typical reverse recovery charge (Qrr) of 19 μC, as specified in Table 1-3 of DS00005276A. This low Qrr value directly reduces turn-off losses in complementary switches and minimizes voltage spikes during hard commutation.
Can the APTDF200A120D16AG be used in parallel configurations?
Yes - the APTDF200A120D16AG is designed with matched dual-diode symmetry and identical thermal paths, enabling reliable parallel operation when installed with balanced busbar routing and uniform clamping force. Its soft-recovery behavior further promotes current sharing under dynamic conditions, unlike conventional fast recovery diodes.
What mounting torque is specified for the M6 terminals of the APTDF200A120D16AG?
The APTDF200A120D16AG specifies a mounting torque of 3–5 N·m for its M6 power terminals, as documented in Table 1-4 (Thermal and Package Characteristics) of DS00005276A. This range ensures optimal electrical contact and thermal interface integrity without risking ceramic substrate fracture or thread stripping.
