Product details
Overview
HERF1007GA from Taiwan Semiconductor is an AEC-Q101-qualified, high-efficiency 800 V repetitive peak reverse voltage (VRRM) ultrafast rectifier in ITO-220AB package, rated for 10 A average forward current (IF), 125 A non-repetitive surge (IFSM), and 80 ns reverse recovery time (trr). It serves as a freewheeling or output rectifier in high-frequency DC-DC converters.
For engineers reviewing the HERF1007GA datasheet, HERF1007GA pinout, HERF1007GA application, or HERF1007GA equivalent, key selection criteria include its 800 V VRRM, 1.7 V max forward voltage at 5 A, 40 pF junction capacitance, 3 °C/W junction-to-case thermal resistance, and dual-die ITO-220AB construction for automotive-grade power conversion.
Technical Context
The HERF1007GA employs ultrafast recovery silicon PN-junction rectification with dual-die configuration in a single ITO-220AB leadframe, enabling high-current handling while maintaining low conduction loss and fast switching transitions. Its trr ≤ 80 ns and CJ = 40 pF support operation in 100 kHz–500 kHz switching topologies.
Thermally, it delivers RθJC = 3 °C/W and operates across –55 °C to +150 °C junction temperature range, with UL 94V-0 molding compound and matte tin-plated leads compliant with J-STD-002 solderability standards.
Key Specifications

| VRRM | 800 V - Maximum repetitive reverse blocking voltage; defines safe operating ceiling in high-voltage DC bus applications. |
| IF | 10 A - Continuous average forward current at case temperature ≤ 100 °C; supports sustained power delivery in SMPS outputs. |
| IFSM | 125 A - Peak non-repetitive surge current (8.3 ms half-sine); withstands inrush and fault transients without failure. |
| trr | ≤ 80 ns - Reverse recovery time at IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A; enables efficient high-frequency switching with low switching loss. |
| VF (max) | 1.7 V @ 5 A, 25 °C - Forward voltage drop per diode; directly determines conduction loss and thermal load in rectifier stage. |
| RθJC | 3 °C/W - Junction-to-case thermal resistance; allows precise heatsink sizing for thermal management in enclosed power modules. |
| CJ | 40 pF @ 1 MHz, 4 V - Junction capacitance per diode; impacts high-frequency EMI and snubber design in resonant converters. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultrafast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH10R06DJF | 600 V VRRM, 10 A IF, trr = 65 ns, TO-220AC package (non-isolated tab) | Limited to ≤600 V DC bus; requires external isolation for heatsink mounting | Select when lower VRRM suffices and cost sensitivity outweighs isolation requirement. |
| IXYS MUR1080CT | 800 V VRRM, 10 A IF, trr = 75 ns, TO-220AB package (isolated tab), but not AEC-Q101 qualified | Not certified for automotive use; lacks UL recognition and halogen-free compliance | Prefer for industrial-only designs where AEC-Q101 and UL are non-mandatory. |
Compared with STTH10R06DJF and IXYS MUR1080CT, the HERF1007GA uniquely combines 800 V rating, AEC-Q101 qualification, UL recognition, and ITO-220AB isolation-making it the only option qualified for thermally demanding, safety-critical automotive DC-DC converters requiring no additional isolation hardware.

FAQ
What is the maximum junction temperature rating for the HERF1007GA?
The HERF1007GA has a maximum junction temperature (TJ) of +150 °C, verified per absolute maximum ratings in the official datasheet. This rating applies across the full operating range and supports reliable operation in under-hood automotive environments and sealed industrial enclosures. Derating curves confirm usable current capacity down to 0 A at 150 °C case temperature. The HERF1007GA must be mounted with appropriate thermal interface material and heatsinking to maintain this limit in continuous operation.
Is the HERF1007GA pin-compatible with the HERF1008GA?
Yes, the HERF1007GA and HERF1008GA share identical ITO-220AB packaging, pinout, and mechanical dimensions - both feature Anode (A1), Cathode (K1), and electrically isolated tab terminals. The sole electrical difference is VRRM: 800 V for HERF1007GA versus 1000 V for HERF1008GA. Designers may substitute HERF1007GA for HERF1008GA only if system-level reverse voltage stress remains below 800 V; no PCB layout change is required for either part.
Does the HERF1007GA require a heatsink in standard operation?
Yes, the HERF1007GA requires a heatsink for operation above ~4 A average forward current at ambient temperatures ≥50 °C, due to its 3 °C/W RθJC and 1.7 V forward drop. At 10 A and 25 °C ambient, junction temperature exceeds 120 °C without thermal management. The ITO-220AB tab is designed for direct bolt-down to aluminum heatsinks; thermal interface material is recommended to minimize RθCS. The HERF1007GA datasheet provides derating curves to determine minimum heatsink size per application.
What does the 'GA' suffix indicate in HERF1007GA?
The 'GA' suffix in HERF1007GA denotes the base version - standard grade, non-AEC-Q101 qualified, RoHS-compliant, halogen-free, and UL Recognized (E-326243). The 'GAH' variant adds AEC-Q101 qualification. Both share identical electrical specs and package; only reliability testing scope differs. The HERF1007GA is intended for industrial and commercial applications where automotive qualification is not mandated, but full safety and environmental compliance is required.
How is reverse recovery time measured for the HERF1007GA?
The HERF1007GA reverse recovery time (trr) is measured per JEDEC standard test conditions: IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A, with specified waveform definitions in Fig.6 of the datasheet. The value ≤ 80 ns reflects worst-case performance at 25 °C junction temperature and is validated across production lots. This parameter directly affects switching loss and EMI in hard-switched topologies; designers should verify actual trr under operating TJ and di/dt conditions using the HERF1007GA's published characteristics curves.
