Product details
Overview
HFA06PB120 from Vishay is an ultrafast soft recovery diode rated for 1200 V repetitive reverse voltage and 6 A average forward current, with typical reverse recovery time of 26 ns at 1.0 A and 200 A/µs dI/dt, designed as a companion rectifier for IGBTs and MOSFETs in high-frequency power conversion systems.
For engineers reviewing the HFA06PB120 datasheet, HFA06PB120 pinout, HFA06PB120 application, or HFA06PB120 equivalent, key selection criteria include its ultrasoft recovery behavior, low Qrr (116 nC), low IRRM (4.4 A), TO-247AC modified package thermal performance, and suitability for motor drives and industrial inverters requiring reduced EMI and switching losses.
Technical Context
The HFA06PB120 employs epitaxial construction and platinum-doped lifetime control to achieve ultrafast yet soft reverse recovery-suppressing snap-off and minimizing dI(rec)M/dt-induced voltage spikes. Its recovery waveform avoids hard turn-off transitions, reducing stress on switching transistors and enabling higher operating frequencies without added snubbing.
Rated for TJ up to 150 °C and qualified to industrial standards, the device delivers stable performance under harsh thermal conditions. With RthJC = 2.0 K/W and low stored charge, it supports efficient heat transfer to heatsinks while maintaining low conduction and switching losses across wide temperature and load ranges.
Key Specifications

| IF(AV) (Average Forward Current) | 6 A at TC = 100 °C - Enables continuous operation in compact heatsink designs for 1–2 kW power stages. |
| trr (Reverse Recovery Time) | 26 ns (typical, IF = 1.0 A, dIF/dt = 200 A/µs) - Allows reliable operation at switching frequencies above 100 kHz with minimal tail current loss. |
| Qrr (Reverse Recovery Charge) | 116 nC (typical, TJ = 25 °C) - Reduces energy dissipation in both diode and switching transistor during turn-on transitions. |
| IRRM (Peak Reverse Recovery Current) | 4.4 A (typical, TJ = 25 °C) - Limits voltage overshoot across snubberless IGBT/MOSFET circuits and eases gate drive design. |
| RthJC (Junction-to-Case Thermal Resistance) | 2.0 K/W - Enables direct mounting to heatsinks with predictable thermal path for thermal management in industrial environments. |
| VFM (Forward Voltage) | 3.0 V max at IF = 6 A, 25 °C - Balances conduction loss and soft-recovery trade-off for high-efficiency power supplies. |

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 |
|---|---|---|---|
| STTH8R06D | 600 V VR, 8 A IF(AV), trr = 35 ns (typ), Qrr = 150 nC - lower voltage rating, higher current, slower recovery. | Suitable for 400 V AC input systems only; not rated for 1200 V DC bus use in industrial inverters. | Select when system DC link voltage ≤ 600 V and higher average current is required; verify snubber requirements due to higher Qrr. |
| IXYS MURB1620CT | 200 V VR, 16 A IF(AV), trr = 30 ns (typ), dual common-cathode TO-247 - much lower voltage, higher current, same package footprint. | Applicable only in low-voltage SMPS outputs (< 100 V); incompatible with high-voltage motor drive DC links. | Use only in secondary-side rectification where VR ≤ 200 V; not a functional substitute for HFA06PB120's 1200 V capability. |
Compared with STTH8R06D and IXYS MURB1620CT, the HFA06PB120 uniquely combines 1200 V blocking capability, 6 A current rating, and sub-30 ns trr with ultrasoft recovery-enabling snubberless operation in 690 V-class industrial drives where neither alternative meets voltage or softness requirements.

FAQ
What is the maximum junction temperature rating for the HFA06PB120?
The HFA06PB120 has a maximum junction temperature (TJ) rating of +150 °C, verified per Vishay's industrial qualification testing. This allows continuous operation in high-ambient environments such as enclosed motor drive cabinets or UPS enclosures with forced-air cooling. Derating curves in the official datasheet (Document Number 93034) define safe operating area limits up to this temperature, and the HFA06PB120 maintains specified trr and Qrr performance within this range.
Does the HFA06PB120 have a common-cathode configuration?
Yes, the HFA06PB120 uses a common-cathode configuration in its TO-247AC modified package: Pin 3 is the cathode and is internally connected to the metal tab, while Pins 1 and 2 are paralleled anodes. This arrangement simplifies PCB layout for dual-anode routing and ensures symmetrical current distribution, making the HFA06PB120 especially effective in bridge-leg freewheeling applications where thermal and electrical balance matters.
What is the typical reverse recovery charge (Qrr) of the HFA06PB120 at 125 °C?
The typical reverse recovery charge (Qrr) of the HFA06PB120 is 233 nC at TJ = 125 °C, as specified in the "DYNAMIC RECOVERY CHARACTERISTICS" table of the official datasheet (Document Number 93034). This elevated Qrr reflects increased carrier lifetime at high temperature but remains significantly lower than standard fast recovery diodes-ensuring continued low switching loss in thermally stressed motor drive applications where the HFA06PB120 operates near its thermal limit.
Can the HFA06PB120 be used as a direct replacement for standard FRDs in existing designs?
The HFA06PB120 can replace many standard fast recovery diodes (FRDs) in high-frequency power converters, but layout and thermal validation are required due to its ultrasoft recovery characteristics. Unlike FRDs, the HFA06PB120 exhibits no snap-off, which may alter voltage transient behavior in snubberless circuits. Engineers must verify gate drive robustness and voltage overshoot margins when substituting the HFA06PB120 into legacy designs originally using FRDs.
What is the thermal resistance from junction to case (RthJC) for the HFA06PB120?
The thermal resistance from junction to case (RthJC) for the HFA06PB120 is 2.0 K/W, measured under standard test conditions per JEDEC JESD51-14. This value is confirmed in the "THERMAL - MECHANICAL SPECIFICATIONS" section of the Vishay datasheet (Document Number 93034) and enables accurate heatsink sizing for industrial applications. When mounted with proper thermal interface material and torque (6–12 kgf·cm), the HFA06PB120 achieves predictable thermal performance essential for long-term reliability in motor drives.
