Product details
Overview
HFA160NJ40C from Infineon Technologies is an ultrafast, soft-recovery dual common-cathode diode optimized for high-frequency power converters and motor drives. It features 400 V reverse voltage rating, 160 A average forward current per leg, 36 ns typical reverse recovery time, 420 nC typical reverse recovery charge, and 260 A/µs peak di(rec)/dt at 125°C - enabling reduced snubbing and EMI in hard-switched topologies.
For engineers reviewing the HFA160NJ40C datasheet, HFA160NJ40C pinout, HFA160NJ40C application, or HFA160NJ40C equivalent, key selection criteria include soft recovery behavior, dual-anode thermal symmetry, TO-244AB mechanical mounting constraints, and junction-to-case thermal resistance of 0.24°C/W with both legs conducting.
Technical Context
The HFA160NJ40C integrates two independent ultrafast diode dies in a single TO-244AB package with shared cathode terminal, enabling interleaved or parallel-leg configurations in three-phase rectifiers and dual-output DC/DC stages. Its soft recovery waveform minimizes voltage overshoot during turn-off, reducing stress on adjacent switching devices.
Thermal design is constrained by dual-leg conduction: junction-to-case resistance drops to 0.24°C/W when both anodes conduct simultaneously, while single-leg operation yields 0.48°C/W. Mounting torque specifications (30–40 lbf·in for terminals, 12–18 lbf·in for center hole) ensure reliable thermal interface contact under high-power cycling.

Pinout & Package
Package: TO-244AB - Insulated metal-base power module with dual lug terminals (Anode 1, Anode 2), common cathode lug, and center mounting hole. Dimensions: 92.71 × 40.26 mm (3.65 × 1.585 in), weight 79 g (2.8 oz).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 – Anode 1 | Forward current input leg 1 | Electrically isolated high-current path; rated for 160 A continuous; requires 30–40 lbf·in terminal torque. |
| 2 – Cathode | Common cathode return | Shared low-inductance return node for both diode legs; must be thermally coupled to heatsink via baseplate. |
| 3 – Anode 2 | Forward current input leg 2 | Independent second high-current path; identical rating and mounting specs as Anode 1; enables balanced dual-leg layouts. |

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 MBR16040CT | 400 V VR, 160 A IF(AV), but trr = 65 ns (typ.), Qrr = 850 nC - higher recovery loss and harder switching edge. | Acceptable in lower-frequency (<50 kHz) welder supplies where EMI filtering is less constrained. | Prefer HFA160NJ40C where trr < 40 ns and Qrr < 500 nC are required for >100 kHz operation. |
| Vishay VS-160CTH04 | 400 V VR, 160 A IF(AV), trr = 42 ns (typ.), Qrr = 510 nC - slightly slower and higher charge than HFA160NJ40C. | Suitable for industrial VFDs with moderate dv/dt requirements; lacks full 125°C di(rec)/dt characterization. | Choose HFA160NJ40C when operating above 100°C junction or requiring guaranteed 260 A/µs di(rec)/dt performance. |
Compared with MBR16040CT and VS-160CTH04, the HFA160NJ40C delivers superior softness (lower IRRM, flatter di(rec)/dt slope), tighter Qrr distribution across temperature, and validated dual-leg thermal coupling - making it optimal for high-density, high-frequency, high-reliability power conversion where recovery behavior directly impacts system efficiency and EMC compliance.

FAQ
What is the maximum continuous forward current rating for the HFA160NJ40C at 100°C case temperature?
The HFA160NJ40C has a maximum continuous forward current rating of 84 A per leg at TC = 100°C, as specified in the Absolute Maximum Ratings table. This derating reflects thermal limitations of the TO-244AB package and ensures safe operation within the -55°C to +150°C junction temperature range. The HFA160NJ40C must be mounted with proper thermal interface material and torque control to maintain this rating.
Does the HFA160NJ40C support dual-leg conduction, and how does that affect thermal performance?
Yes, the HFA160NJ40C is designed for dual-leg conduction with a shared cathode. When both anodes conduct simultaneously, the junction-to-case thermal resistance improves to 0.24°C/W - half that of single-leg operation (0.48°C/W). This is confirmed in the Thermal-Mechanical Characteristics table and enables balanced thermal loading in three-phase bridge rectifiers. The HFA160NJ40C's mechanical layout and mounting torque specs (30–40 lbf·in) ensure consistent thermal contact under dual-leg conditions.
What is the typical reverse recovery charge (Qrr) of the HFA160NJ40C, and under what test conditions is it measured?
The typical reverse recovery charge (Qrr) of the HFA160NJ40C is 420 nC, measured per leg at TJ = 25°C, IF = 80 A, dif/dt = 200 A/µs, and VR = 200 V, as stated in the Dynamic Recovery Characteristics table. This value increases to 1200–3200 nC at TJ = 125°C, reflecting temperature-dependent carrier lifetime effects. The HFA160NJ40C's Qrr is among the lowest in its class, contributing to reduced switching losses in high-frequency converters.
How does the soft recovery characteristic of the HFA160NJ40C reduce EMI in power circuits?
The HFA160NJ40C's soft recovery minimizes the rate of change of reverse current (di(rec)/dt) during turn-off - specified as 260 A/µs at 125°C - which reduces high-frequency spectral content in voltage transients. This directly lowers conducted and radiated EMI, allowing smaller EMI filters and eliminating snubbers in many applications. The HFA160NJ40C achieves this through optimized carrier lifetime control and tailored doping profiles, as documented in the HEXFRED™ characterization methodology.
What mounting torque values are required for the HFA160NJ40C terminals and center hole?
The HFA160NJ40C requires 30–40 lbf·in (3.4–4.6 N·m) terminal torque for both anode lugs and cathode lug, and 12–18 lbf·in (1.4–2.1 N·m) torque for the center mounting hole, as specified in the Mechanical Characteristics table. These values ensure optimal thermal contact without damaging the TO-244AB baseplate or deforming mounting surfaces. The HFA160NJ40C's mounting instructions explicitly require gradual tightening in 5–10 lbf·in steps to avoid uneven pressure distribution.
