Product details
Overview
HERAF807G from Taiwan Semiconductor is an 8 A, 800 V glass-passivated high-efficiency fast recovery rectifier in ITO-220AC package, featuring 1.7 V max forward voltage at 8 A and 80 ns reverse recovery time, used in DC-DC converters and switching inverters for industrial power supplies.
For engineers reviewing the HERAF807G datasheet, HERAF807G pinout, HERAF807G application, or HERAF807G equivalent, key selection criteria include repetitive peak reverse voltage (800 V), surge current capability (150 A), junction-to-case thermal resistance (2 °C/W), and AEC-Q101 qualification status where specified.
Technical Context
This single-die fast recovery rectifier employs a glass-passivated PN junction to achieve low conduction loss and stable high-temperature operation up to 150 °C junction temperature. Its 80 ns trr and 60 pF junction capacitance support high-frequency switching in SMPS topologies.
The ITO-220AC package provides direct case-to-heatsink thermal path with 0.56 N·m maximum mounting torque and UL 94V-0 molding compound. Polarity is marked on device body; terminals are matte tin-plated per J-STD-002 solderability standard.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 800 V - Maximum repetitive reverse blocking voltage; defines usable input voltage range in bridge or freewheeling configurations |
| IF | 8 A - Continuous average forward current at TC = 100 °C; determines steady-state power handling capacity |
| IFSM | 150 A - Non-repetitive surge current (8.3 ms half-sine); supports inrush and fault-current tolerance |
| VF (max) | 1.7 V @ 8 A, 25 °C - Forward voltage drop directly impacts conduction loss and thermal design margin |
| trr | 80 ns - Reverse recovery time; limits minimum switching frequency and affects EMI in hard-switched converters |
| RθJC | 2 °C/W - Junction-to-case thermal resistance; enables heatsink sizing for target TJ under defined power dissipation |
| CJ | 60 pF @ 1 MHz, VR = 4 V - Junction capacitance influences high-frequency switching behavior and snubber design |
Pinout & Package
ITO-220AC package: single-ended, 3-terminal outline with isolated tab (cathode-connected), matte tin-plated leads, UL 94V-0 mold compound, 1.70 g typical weight, polarity marked on body.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage fast recovery rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH8R06DJF | 600 V VRRM, 100 ns trr, TO-220AC package, same 8 A IF rating | Limited to ≤600 V systems; higher trr increases switching loss in >50 kHz designs | Select when system VRRM requirement is ≤600 V and cost sensitivity outweighs 20 ns trr penalty |
| IXYS MUR880E | 800 V VRRM, 75 ns trr, TO-220AC, 125 A IFSM, but VF = 2.1 V (max) | Higher VF increases conduction loss; preferred where surge margin >150 A is critical | Choose when surge immunity is prioritized over thermal efficiency at full load |
Compared with STTH8R06DJF and IXYS MUR880E, the HERAF807G delivers optimal balance of 800 V blocking, 80 ns trr, and 1.7 V VF in a UL-recognized, halogen-free ITO-220AC package-making it preferred for space-constrained, thermally demanding 800 V industrial converters.

FAQ
What is the maximum junction temperature rating for HERAF807G?
The HERAF807G has a maximum junction temperature (TJ MAX) of +150 °C, validated across its full operating range from –55 °C to +150 °C. This rating enables use in high-ambient environments such as enclosed industrial power supplies and under-hood automotive auxiliary systems, provided thermal design maintains actual TJ ≤150 °C using the specified RθJC of 2 °C/W.
Is HERAF807G AEC-Q101 qualified?
The base HERAF807G part is not AEC-Q101 qualified; however, the variant HERAF807GH (with 'H' suffix) is explicitly qualified per AEC-Q101 Rev D. The datasheet confirms AEC-Q101 availability as an option across the HERAF801G–HERAF808G family, and ordering code HERAF807GH denotes the qualified version with identical electrical specs and ITO-220AC packaging.
What is the reverse recovery time (trr) of HERAF807G and how is it measured?
The HERAF807G has a maximum reverse recovery time (trr) of 80 ns, measured under conditions of IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A per JEDEC standards. This value applies specifically to HERAF806G–HERAF808G variants and reflects performance at 25 °C ambient; trr increases moderately at elevated junction temperatures but remains within specification up to TJ = 125 °C.
Does HERAF807G have a built-in thermal protection mechanism?
No, the HERAF807G is a passive discrete rectifier and does not incorporate active thermal protection or shutdown circuitry. Thermal management relies entirely on external design: proper heatsinking using the ITO-220AC tab, adherence to the 2 °C/W RθJC limit, and derating per the forward current derating curve in the datasheet. Safe operation requires maintaining TJ ≤150 °C under worst-case power dissipation.
What is the marking code format printed on the HERAF807G device body?
The HERAF807G is marked with "HERAF807G" followed by date code (YWW), factory code (F), and green compound indicator (G). Per the package marking diagram, "HERAF807G" is the full part identifier; "G" denotes RoHS-compliant halogen-free molding compound, not a grade or revision suffix. No additional alphanumeric characters indicate electrical binning or test lot.
