Product details
Overview
HFA100MD60C from Infineon Technologies is an ultrafast, soft-recovery HEXFRED™ diode optimized for high-frequency power conditioning. It features 600 V cathode-to-anode voltage rating, 100 A average forward current (IF(AV)), 33 ns typical reverse recovery time (trr), 300 nC typical reverse recovery charge (Qrr), and operates with soft recovery to minimize EMI/RFI-ideal for switch-mode power supplies and motor drives.
For engineers reviewing the HFA100MD60C datasheet, HFA100MD60C pinout, HFA100MD60C application, or HFA100MD60C equivalent, key selection criteria include its isolated TO-244AB package, dual-anode single-cathode configuration, soft recovery behavior at high di/dt, and thermal performance under both single-leg and dual-leg conduction conditions.
Technical Context
The HFA100MD60C is a dual-leg, common-cathode ultrafast diode in an electrically isolated TO-244AB package, with terminals assigned as Anode 1, Cathode, and Anode 2. Its soft recovery waveform reduces snubber requirements and system-level EMI generation during high-speed switching transitions.
Thermal design is enabled by low junction-to-case thermal resistance: 0.70 °C/W (single leg conducting) and 0.35 °C/W (both legs conducting), paired with case-to-sink resistance of 0.10 °C/W on greased flat surfaces. Recovery parameters-including trr, IRRM, Qrr, and di(rec)M/dt-are fully characterized across temperature (25°C to 125°C) and di/dt (100–2000 A/µs).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VR | 600 V - Maximum blocking voltage before avalanche; defines maximum DC bus or flyback voltage it can safely withstand. |
| IF(AV) | 100 A - Average forward current per leg at TC = 25°C; sets continuous conduction capability in rectifier or freewheeling roles. |
| trr (typ.) | 33 ns - Reverse recovery time at IF = 1.0 A, di/dt = 200 A/µs, VR = 30 V; indicates speed for high-frequency hard-switched topologies. |
| Qrr (typ.) | 300 nC - Stored charge cleared during turn-off; directly impacts switching loss and snubber sizing in bridge configurations. |
| RthJC (dual leg) | 0.35 °C/W - Junction-to-case thermal resistance when both anodes conduct; enables accurate heatsink sizing for full-rated operation. |
| di(rec)M/dt (typ.) | 240 A/µs - Peak rate of fall of recovery current at TJ = 125°C; determines EMI spectral content and layout sensitivity. |
| VFM @ 100A | 1.4–1.6 V - Forward voltage drop at rated current; defines conduction loss and thermal load under full-load conditions. |
Pinout & Package
Package: TO-244AB (Isolated Base), metal-base module with electrically isolated mounting surface. Dimensions: 63.50 × 40.26 × 15.75 mm (2.500 × 1.585 × 0.620 in). Mounting torque: 30–40 lbf·in (3.4–4.6 N·m); requires flat, burr-free surface and thin thermal grease layer.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| Anode 2 (Lug) | Input terminal for second diode leg | Connects to second switching node (e.g., lower switch source or alternate phase) - supports interleaved or dual-phase designs. |
Key Features
| Feature | Design Value |
|---|---|
| Soft recovery waveform | Eliminates need for snubbers in most applications by suppressing voltage overshoot and ringing during turn-off. |
| Extensive di/dt characterization | Qrr, trr, IRRM, and di(rec)M/dt measured across 100–2000 A/µs range - enables precise loss modeling in real-world switching conditions. |
| Isolated base construction | Electrically isolated mounting surface allows direct heatsink attachment without insulating pads - simplifies thermal management and improves reliability. |
| Low RthJC (dual-leg) | 0.35 °C/W thermal resistance enables >71 W power dissipation at TC = 100°C - supports high-power density converter designs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultrafast soft-recovery diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IXYS MUR10060CT | TO-247AC package, non-isolated base, 600 V VR, 100 A IF(AV), trr ≈ 45 ns, Qrr ≈ 420 nC | Lacks isolated mounting surface; requires insulating pad; higher Qrr increases switching loss in high-di/dt circuits | Preferred where cost is prioritized over thermal integration and EMI control |
| Vishay VS-100CTH06-M3 | TO-247AD package, isolated base, 600 V VR, 100 A IF(AV), trr ≈ 35 ns, Qrr ≈ 320 nC, RthJC = 0.40 °C/W (dual) | Slightly higher RthJC and marginally slower trr; same footprint compatibility but different terminal geometry | Drop-in alternative only after verifying mechanical fit and thermal interface compliance |
Compared with MUR10060CT and VS-100CTH06-M3, the HFA100MD60C delivers superior thermal performance (0.35 °C/W dual-leg RthJC), tighter trr consistency across temperature, and lower Qrr-making it optimal for high-density, high-efficiency converters where thermal headroom and EMI margins are constrained.

FAQ
What is the maximum continuous forward current rating for HFA100MD60C at 100°C case temperature?
The HFA100MD60C supports 40 A continuous forward current per leg at TC = 100°C. This derating reflects thermal limits under sustained conduction; the device's 0.35 °C/W dual-leg RthJC enables this rating when properly mounted on a heatsink with ≤0.10 °C/W case-to-sink resistance. Always verify actual TC via thermocouple measurement during validation testing of the HFA100MD60C in your application.
Does HFA100MD60C have electrically isolated mounting base?
Yes, the HFA100MD60C uses a TO-244AB package with an electrically isolated base, allowing direct attachment to grounded heatsinks without thermal interface insulation. This isolation is confirmed in the outline drawing and thermal-mechanical specifications, where "ISOLATED" is explicitly labeled. The HFA100MD60C's isolated base eliminates risk of short circuits in multi-phase or high-side referenced layouts.
What is the typical reverse recovery charge (Qrr) of HFA100MD60C and how does it vary with temperature?
The HFA100MD60C has a typical Qrr of 300 nC at TJ = 25°C and IF = 50 A, rising to 780 nC at TJ = 125°C under identical test conditions. This strong temperature dependence is documented in Figure 7 of the datasheet and must be accounted for in loss calculations at elevated junction temperatures. Designers should use the HFA100MD60C's Qrr vs. di/dt and temperature curves-not just typ values-to size snubbers and estimate turn-off losses accurately.
Can HFA100MD60C be used in avalanche mode, and what is its rated non-repetitive avalanche energy?
Yes, the HFA100MD60C is rated for non-repetitive avalanche energy (EAS) of 220 µJ under specified test conditions (L = 100 µH, duty cycle limited by max TJ). This capability allows limited energy absorption during transient overvoltage events, such as inductive kickback in motor drive freewheeling. However, the HFA100MD60C is not designed for repetitive avalanche operation; sustained avalanche stresses will degrade reliability and must be avoided in normal HFA100MD60C usage.
What mounting torque is recommended for HFA100MD60C, and why is surface preparation critical?
The HFA100MD60C requires mounting torque between 30–40 lbf·in (3.4–4.6 N·m), applied gradually in 5–10 lbf·in increments. Surface preparation is critical because the datasheet specifies that the mounting surface must be smooth, flat, and free of burrs or protrusions; any irregularity compromises thermal contact and raises RthCS beyond the rated 0.10 °C/W. Applying a thin, even film of thermal grease-as specified for the HFA100MD60C-is mandatory to achieve published thermal performance.
