Product details
Overview
HERF1007GAH from Taiwan Semiconductor is an AEC-Q101-qualified, 10A, 800V high-efficiency ultrafast rectifier in ITO-220AB package with dual-die configuration, 125A surge rating, 3°C/W junction-to-case thermal resistance, and 80ns reverse recovery time - deployed in automotive DC-DC converters and industrial switching inverters.
For engineers reviewing the HERF1007GAH datasheet, HERF1007GAH pinout, HERF1007GAH application, or HERF1007GAH equivalent, key selection criteria include its 800V VRRM, AEC-Q101 qualification status, 1.7V max forward voltage at 5A, 40pF junction capacitance, and ITO-220AB mechanical compatibility with heatsink mounting.
Technical Context
This device implements a dual-die ultrafast recovery rectifier architecture optimized for high-frequency switching topologies. It delivers low conduction loss (VF ≤ 1.7V @ 5A, 25°C) and fast switching (trr ≤ 80ns), enabling efficient operation in hard-switched SMPS and freewheeling paths where di/dt stress and reverse recovery energy are critical.
The ITO-220AB package provides direct metal tab thermal path to heatsink, supporting continuous 10A operation up to 150°C junction temperature. Its UL 94V-0 molding compound and matte tin-plated leads meet automotive solderability and flammability requirements per J-STD-002 and JESD201 Class 2.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 800 V - Maximum repetitive reverse blocking voltage; defines usable input voltage range in boost/flyback stages |
| IF | 10 A - Continuous average forward current; sets minimum heatsink sizing for 100% duty-cycle operation |
| IFSM | 125 A - Non-repetitive surge rating (8.3ms half-sine); supports inrush and fault-current handling |
| trr | 80 ns - Reverse recovery time; limits switching losses and EMI in >100kHz converters |
| RθJC | 3 °C/W - Junction-to-case thermal resistance; enables precise thermal modeling with external heatsink |
| VF (max) | 1.7 V @ 5A, 25°C - Forward voltage drop; determines conduction loss and thermal load at rated current |
| CJ | 40 pF @ 1MHz, 4V - Junction capacitance; affects snubber design and high-frequency ringing behavior |
Pinout & Package
Package: ITO-220AB - Insulated TO-220 variant with electrically isolated metal tab, UL 94V-0 molding compound, matte tin-plated leads, and 0.56 N·m maximum mounting torque. Polarity marked on device body.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Tab) | Power input terminal (cathode-connected case in standard TO-220AB) | Electrically isolated metal tab serves as anode connection; requires insulated mounting hardware |
| Cathode (Lead 1) | Power output terminal | Single lead cathode output; compatible with standard PCB footprint for ITO-220AB |
| Case (Isolated) | Thermal interface only - no electrical connection | Tab is internally isolated from both terminals; enables floating ground designs without insulating washers |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive powertrain and chassis applications per stress test requirements |
| Ultrafast recovery (trr ≤ 80ns) | Reduces switching loss and dv/dt-induced cross-conduction in synchronous rectifier circuits |
| Dual-die construction | Enables higher current density and improved thermal distribution vs. single-die equivalents |
| UL Recognized (E-326243) | Meets safety standards for end-equipment certification in industrial and automotive systems |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultrafast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH10R06DJF | 600V VRRM, 10A, 60ns trr, TO-220AC package (non-isolated tab) | Lacks AEC-Q101 qualification and 800V blocking; unsuitable for 800V bus systems | Select when lower VRRM and faster trr are prioritized over automotive qualification and isolation |
| IXYS MUR1080CT | 800V VRRM, 10A, 75ns trr, TO-220AB (non-isolated tab), no AEC-Q101 | Same voltage/current rating but non-isolated case requires insulating hardware; no automotive qualification | Choose for cost-sensitive industrial use where tab isolation and AEC-Q101 are not required |
Compared with STTH10R06DJF and IXYS MUR1080CT, HERF1007GAH uniquely combines 800V blocking, AEC-Q101 qualification, and electrically isolated ITO-220AB packaging - making it the only option qualified for automotive 48V/800V systems requiring both safety isolation and thermal robustness.

FAQ
What does the 'H' suffix in HERF1007GAH signify?
The 'H' suffix in HERF1007GAH indicates full AEC-Q101 qualification - verified through temperature cycling, humidity bias, high-temperature operating life, and mechanical shock testing per automotive reliability standards. HERF1007GAH is not a sample or pre-qualified part; it carries official AEC-Q101 certification for use in automotive powertrain and chassis systems.
Is HERF1007GAH pin-compatible with standard TO-220AB rectifiers?
No - HERF1007GAH uses the ITO-220AB package, which features an electrically isolated metal tab. Unlike standard TO-220AB devices where the tab is the cathode, HERF1007GAH's tab is the anode and fully insulated. PCB layout must accommodate isolation, and mounting hardware requires dielectric washers or shoulder screws.
What is the maximum continuous junction temperature for HERF1007GAH?
The maximum continuous junction temperature for HERF1007GAH is +150°C, as specified in the Absolute Maximum Ratings table. Derating begins above +25°C ambient, and thermal design must ensure RθJA (junction-to-ambient) remains within limits using the measured RθJC = 3°C/W and heatsink performance.
Does HERF1007GAH support parallel operation for higher current handling?
HERF1007GAH supports parallel operation only with matched units and external current-sharing resistors or active balancing. Its positive VF temperature coefficient enables moderate inherent sharing, but mismatched trr or thermal gradients can cause imbalance. For 20A+ designs, consult TSC Application Note AN-HERF-01 before implementing parallel HERF1007GAH devices.
How does HERF1007GAH differ from HERF1008GA?
HERF1007GAH and HERF1008GA share identical package, thermal specs, and AEC-Q101 qualification, but differ in rated blocking voltage: HERF1007GAH is 800V VRRM, while HERF1008GA is 1000V VRRM. Both exhibit identical forward characteristics (VF, IF, trr) and thermal performance (RθJC, TJMAX). Selection depends strictly on system voltage margin requirements.
