Product details
Overview
HERF1002GH from Taiwan Semiconductor is a 10 A, 100 V AEC-Q101-qualified high-efficiency rectifier diode in ITO-220AB package with dual-die configuration, 1.0 V forward voltage at 5 A/25°C, 125 A surge rating, and 50 ns reverse recovery time - used in automotive-grade DC-DC converters and switching inverters.
For engineers reviewing the HERF1002GH datasheet, HERF1002GH pinout, HERF1002GH application, or HERF1002GH equivalent, key selection factors include its AEC-Q101 qualification, 100 V repetitive peak reverse voltage, low VF performance, thermal resistance of 3°C/W, and ITO-220AB mechanical compatibility for high-power mounting.
Technical Context
This device is a single-phase, dual-die, high-current silicon rectifier optimized for fast-switching power conversion. It delivers low conduction loss (VF = 1.0 V typ. @ 5 A, 25°C) and fast recovery (trr = 50 ns max), enabling high efficiency in 100 kHz–500 kHz SMPS topologies.
Designed for automotive under-hood environments, HERF1002GH operates across –55°C to +150°C junction temperature range, features UL 94V-0 molding compound, matte tin-plated leads compliant with J-STD-002, and meets JESD201 Class 2 whisker resistance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - maximum repetitive reverse blocking voltage; defines safe operating limit in flyback/freewheeling paths |
| IF | 10 A - continuous forward current rating; supports sustained 10 A DC output in compact converter designs |
| IFSM | 125 A - non-repetitive surge current (8.3 ms half-sine); handles inrush and fault transients without failure |
| VF | 1.0 V (typ.) @ 5 A, 25°C - low conduction loss reduces heat generation and improves system efficiency |
| trr | 50 ns (max) - fast reverse recovery minimizes switching losses and EMI in high-frequency converters |
| RθJC | 3°C/W - low junction-to-case thermal resistance enables direct heatsink mounting for thermal management |
Pinout & Package
Package: ITO-220AB - insulated thermally enhanced outline with isolated collector tab, UL 94V-0 rated epoxy, matte tin-plated leads, 0.56 N·m max mounting torque, and polarity marked on case.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Lead 1) | Input current entry point | Connected to source side in freewheeling or rectification path; requires PCB trace sizing for 10 A continuous |
| Cathode (Lead 2) | Output current exit point | Common output node for dual-die configuration; electrically tied internally to cathode tab |
| Collector Tab (Case) | Thermal & electrical cathode connection | Isolated metal tab serves as primary heat dissipation path and cathode return; must be mounted to heatsink with insulating washer if voltage isolation required |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive under-hood applications including engine control, ADAS power supplies, and EV auxiliary converters |
| Low VF (1.0 V typ.) | Reduces conduction loss by ~25% vs. standard FR10x series at 5 A, lowering thermal stress in space-constrained modules |
| Dual-die configuration | Enables parallel operation within single footprint, improving current sharing and reliability over discrete dual-diode solutions |
| UL Recognized (E-326243) | Meets safety requirements for end-equipment certification in industrial and automotive power systems |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-efficiency rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH10R06DJF | 600 V VRRM, 1.75 V VF @ 5 A, TO-220AC package, no AEC-Q101 | Higher voltage grade; suited for 400 V bus systems but less efficient at 100 V operation | Choose when higher reverse voltage margin is required and automotive qualification is not mandatory |
| VS-10ETH06-M3 | 600 V VRRM, 1.25 V VF @ 5 A, TO-220AC, AEC-Q101 qualified | Same qualification level but higher VF increases conduction loss by ~25% vs. HERF1002GH | Prefer HERF1002GH for 100 V systems where low VF and thermal performance are prioritized |
Compared with STTH10R06DJF and VS-10ETH06-M3, HERF1002GH offers optimal balance of 100 V rating, 1.0 V VF, AEC-Q101 compliance, and 3°C/W thermal resistance - making it uniquely suited for thermally constrained, automotive-grade 100 V rectification where efficiency and reliability are co-prioritized.

FAQ
What is the maximum junction temperature rating for HERF1002GH?
The HERF1002GH has a maximum junction temperature (TJ) rating of +150°C, verified per absolute maximum ratings table in the official Taiwan Semiconductor datasheet (Version I2105). This allows reliable operation in under-hood automotive environments and high-ambient industrial settings. Derating curves confirm full 10 A current capability up to 100°C case temperature when properly heatsinked.
Is HERF1002GH pin-compatible with standard TO-220 rectifiers?
No - HERF1002GH uses the ITO-220AB package, which features an electrically isolated collector tab and different lead frame geometry versus standard TO-220AC/AB. While footprint dimensions are similar, the isolation and internal die configuration require verification of creepage/clearance and thermal interface design. Mounting torque must not exceed 0.56 N·m.
Does HERF1002GH support bidirectional current flow?
No - HERF1002GH is a unidirectional silicon rectifier diode. It conducts only from anode to cathode and blocks reverse current up to its 100 V VRRM rating. Bidirectional operation would require external circuitry such as back-to-back configurations or active switching devices; HERF1002GH itself does not support reverse conduction.
What is the reverse leakage current specification for HERF1002GH at elevated temperature?
At TJ = 125°C and rated VR = 100 V, HERF1002GH exhibits a maximum reverse leakage current (IR) of 400 µA per diode, as specified in the Electrical Specifications table. At 25°C, IR is ≤10 µA. This low leakage supports stable operation in high-temperature power supplies without significant standby loss.
How does the dual-die configuration of HERF1002GH affect its thermal performance?
The dual-die configuration in HERF1002GH shares the same ITO-220AB thermal path, maintaining the specified RθJC of 3°C/W. Unlike paralleled discrete diodes, this monolithic integration ensures matched thermal and electrical characteristics, eliminating current imbalance risks and simplifying PCB layout - critical for high-reliability automotive applications.
