Product details
Overview
VS-HFA140NJ60CPBF from Vishay Semiconductors is a HEXFRED® ultrafast soft recovery diode in a TO-244 package, configured as two common-cathode diodes. It delivers 167 A peak forward current, 600 V reverse voltage rating, and ultra-low reverse recovery charge (Qrr = 340–900 nC at 25 °C), enabling high-efficiency operation in high-frequency power converters and motor drives.
For engineers reviewing the VS-HFA140NJ60CPBF datasheet, VS-HFA140NJ60CPBF pinout, VS-HFA140NJ60CPBF application, or VS-HFA140NJ60CPBF equivalent, key selection criteria include soft recovery behavior (trr = 80–120 ns at 70 A/200 A/μs), low forward voltage (VFM = 1.58 V typ. at 140 A), thermal resistance (RthJC = 0.38 °C/W per leg), and industrial-grade qualification.
Technical Context
This dual-diode module is engineered for high-frequency switching topologies where EMI reduction and snubberless operation are critical. Its soft reverse recovery (dI(rec)M/dt = 300 A/μs typ. at 25 °C) and low Qrr minimize voltage overshoot and ringing during turn-off transitions.
The TO-244 package features isolated lug terminals for anode 1 and anode 2, with a shared cathode baseplate optimized for direct heatsink mounting. Thermal performance is defined by RthJC = 0.38 °C/W per leg and RthCS = 0.10 °C/W typical, supporting high-power density designs up to 150 °C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VR | 600 V - blocks DC bus voltages in 400 VAC input rectification and 3-phase IGBT inverter freewheeling paths |
| IF(peak) | 167 A at TC = 25 °C - supports short-duration surge currents in motor startup and regenerative braking |
| trr | 80–120 ns at IF = 70 A, dIF/dt = 200 A/μs - enables >100 kHz switching without excessive switching loss or EMI |
| Qrr | 340–900 nC at TJ = 25 °C - reduces energy dissipation in hard-switched converters and limits diode-induced voltage spikes |
| VFM | 1.58 V typ. at IF = 140 A - lowers conduction loss in high-current output stages of UPS and solar inverters |
| RthJC | 0.38 °C/W per leg - allows thermal design with ≤ 60 °C temperature rise at 84 A DC, simplifying heatsink sizing |
| TJ max | +150 °C - qualified for continuous operation in industrial environments with ambient up to +85 °C and forced-air cooling |
Pinout & Package
Package: TO-244 - insulated metal-base package with two isolated anode lugs and a common cathode baseplate, designed for direct bolt-down heatsink mounting and high-current PCB-free power modules.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode 1 (Lug) | Input terminal for first diode leg | Carries up to 140 A DC; requires torque-controlled mounting (30–40 lbf·in) to ensure low thermal resistance |
| Anode 2 (Lug) | Input terminal for second diode leg | Electrically isolated from Anode 1; enables dual-channel freewheeling or phase-leg configuration |
| Cathode (Baseplate) | Common output node for both diodes | Mounted directly to heatsink; serves as primary thermal path and electrical return; must be electrically isolated from chassis unless system ground referenced |
Key Features
| Feature | Design Value |
|---|---|
| Ultrafast soft recovery | trr = 80–120 ns with soft dI(rec)M/dt profile eliminates need for snubbers in most 10–100 kHz converter designs |
| Low Qrr | 340–900 nC at 25 °C reduces turn-off losses by >40% vs. standard fast recovery diodes in same voltage class |
| Industrial qualification | Designed and tested per industrial reliability standards; operates continuously from –55 °C to +150 °C junction |
| TO-244 dual-lug layout | Enables independent routing of two high-current paths while sharing thermal mass-ideal for 3-phase bridge half-bridge legs |
| UL recognition | UL file E222165 certified for safety compliance in end equipment requiring regulatory approval |
Applications
| Motor Drives | Solar Inverters |
|---|---|

IC Role / Device Role / Timing Role: Zero-voltage switching (ZVS) auxiliary diode managing reactive current in series-resonant LC tanks. Use Value: Ultra-low trr and soft recovery prevent parasitic oscillation during ZVS transitions, increasing inverter reliability at high dV/dt stress. |
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 MBR16060CT | 600 V, 160 A dual common-cathode Schottky; zero Qrr but limited to TJ ≤ 150 °C and VR ≤ 600 V; higher VFM (~1.75 V at 140 A) | Not suitable for line-frequency rectification due to leakage; best for low-VF priority in <100 kHz DC/DC where TJ stays <125 °C | Select when lowest conduction loss dominates and reverse leakage can be managed thermally |
| STMicroelectronics STTH1606D | 600 V, 160 A dual common-cathode ultrafast; trr = 65 ns (harder recovery), Qrr = 520 nC, VFM = 1.7 V at 140 A, RthJC = 0.45 °C/W | Higher EMI generation due to faster but harder recovery; requires snubber in >30 kHz hard-switched topologies | Select when cost sensitivity outweighs EMI filtering budget and thermal margin permits higher RthJC |
Compared with MBR16060CT and STTH1606D, VS-HFA140NJ60CPBF uniquely balances ultra-low Qrr, soft recovery, and 167 A peak rating in TO-244-making it optimal for industrial motor drives and solar inverters where snubber elimination and thermal robustness are mandatory.

FAQ
What is the maximum continuous forward current rating for VS-HFA140NJ60CPBF at 100 °C case temperature?
The VS-HFA140NJ60CPBF is rated for 84 A DC continuous forward current at TC = 100 °C per leg. This derating reflects thermal limits of the TO-244 package and ensures safe operation within the +150 °C maximum junction temperature specification. The 167 A rating applies only at TC = 25 °C and is intended for short-duration surge conditions-not sustained conduction. Designers must verify heatsink interface resistance and airflow to maintain TC ≤ 100 °C under full-load conditions.
Does VS-HFA140NJ60CPBF support snubberless operation, and under what conditions?
Yes, VS-HFA140NJ60CPBF supports snubberless operation due to its soft reverse recovery characteristic (dI(rec)M/dt = 300 A/μs typ. at 25 °C) and low Qrr (340–900 nC). This is validated for hard-switched topologies up to 100 kHz with dIF/dt ≤ 200 A/μs and VR ≤ 200 V. At higher dIF/dt or elevated TJ (e.g., 125 °C), Qrr increases to 980–2300 nC, and snubber evaluation is recommended for critical EMI-sensitive designs.
What is the thermal resistance from junction to case (RthJC) for VS-HFA140NJ60CPBF, and how is it measured?
The VS-HFA140NJ60CPBF has a thermal resistance of RthJC = 0.38 °C/W per leg, measured from the silicon die junction to the mounting baseplate surface under standardized test conditions (per JEDEC JESD51-14). This value assumes proper mounting with thermal grease and torque applied to both anode lugs (30–40 lbf·in). The module's dual-leg structure yields 0.19 °C/W total RthJC when both legs conduct simultaneously and share thermal mass.
Is VS-HFA140NJ60CPBF RoHS-compliant and lead-free?
Yes, VS-HFA140NJ60CPBF is lead (Pb)-free and RoHS-compliant, as confirmed by the "PbF" suffix in its part number and Vishay's material declaration document #99912. It meets EU RoHS Directive 2011/65/EU and is compatible with standard Pb-free reflow soldering profiles. No exemption claims apply-the device contains no intentionally added lead, cadmium, mercury, hexavalent chromium, PBB, or PBDE.
How does the dual common-cathode configuration of VS-HFA140NJ60CPBF benefit three-phase inverter designs?
The dual common-cathode configuration of VS-HFA140NJ60CPBF allows each anode lug to serve one phase-leg of a three-phase inverter while sharing a single low-inductance cathode return path. This reduces layout parasitics, improves current sharing between legs, and simplifies heatsink integration-especially in compact half-bridge modules. Unlike discrete diodes, this integrated structure ensures matched thermal and electrical characteristics across both legs, minimizing imbalance during dynamic load transients.
