Product details
Overview
HERF1603GH from Taiwan Semiconductor is a 16A, 200V AEC-Q101-qualified high-efficiency ultrafast rectifier in ITO-220AB package with dual-die configuration, 1.5°C/W junction-to-case thermal resistance, and 50ns reverse recovery time - used in automotive DC-DC converters and switching inverters.
For engineers reviewing the HERF1603GH datasheet, HERF1603GH pinout, HERF1603GH application, or HERF1603GH equivalent, key selection criteria include its 200V repetitive peak reverse voltage, 125A surge rating, 1.0V max forward voltage at 8A/25°C, AEC-Q101 qualification, and ITO-220AB mechanical compatibility with heatsink mounting.
Technical Context
This device implements a dual-die ultrafast rectifier architecture optimized for high-current switching applications. It delivers low conduction loss (VF ≤ 1.0 V @ IF = 8 A, TJ = 25°C) and fast switching (trr ≤ 50 ns), enabling high-frequency operation in automotive-grade power supplies.
The ITO-220AB package supports direct heatsink mounting with 0.56 N·m maximum torque and meets UL 94V-0 flammability and JESD201 Class 2 whisker resistance standards - critical for under-hood automotive reliability.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultrafast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1602CW | 16 A, 200 V, TO-247AC package; trr = 45 ns; VF = 1.15 V @ 8 A | Higher VF increases conduction loss; TO-247AC offers larger creepage but no isolated tab | Prefer HERF1603GH where ITO-220AB footprint and lower VF are critical for thermal-limited layouts |
| IXYS MUR1620CT | 16 A, 200 V, TO-220AB package; trr = 60 ns; VF = 1.1 V @ 8 A; not AEC-Q101 qualified | Lacks automotive qualification; slightly slower recovery and higher VF impact efficiency in high-temp environments | HERF1603GH is preferred for AEC-Q101-compliant designs requiring tighter trr and lower VF at 125°C junction |
Compared with STTH1602CW and IXYS MUR1620CT, HERF1603GH provides the lowest forward voltage (≤1.0 V), fastest recovery (≤50 ns), and only AEC-Q101-qualified option in ITO-220AB - making it optimal for space-constrained, thermally demanding automotive power stages.

FAQ
What is the maximum junction temperature rating for HERF1603GH?
The HERF1603GH has a maximum junction temperature (TJ) rating of +150°C, verified per AEC-Q101 stress test conditions. This rating enables operation in under-hood automotive environments where ambient temperatures exceed 105°C, provided thermal design maintains junction temperature below this limit using the specified 1.5°C/W RθJC path.
Is HERF1603GH pin-compatible with other devices in the HERF160xG family?
Yes, all HERF160xG variants - including HERF1603GH - share identical ITO-220AB package dimensions, pinout, and terminal assignments. The only differences are VRRM rating (200 V for HERF1603GH) and associated electrical parameters such as VF and trr, allowing direct substitution within the same voltage class when thermal and surge margins permit.
Does HERF1603GH require heatsinking in standard 16 A operation?
Yes, HERF1603GH requires heatsinking for continuous 16 A operation at ambient temperatures above 50°C. With RθJC = 1.5°C/W and typical VF ≈ 0.95 V, power dissipation exceeds 15 W - necessitating a heatsink to maintain TJ ≤ 150°C. Derating curves in the datasheet specify allowable current vs. case temperature.
What does the 'H' suffix in HERF1603GH signify?
The 'H' suffix in HERF1603GH indicates full AEC-Q101 qualification per Rev D, including stress tests for temperature cycling, high-temperature operating life, unbiased highly accelerated stress test (uHAST), and mechanical shock. This distinguishes HERF1603GH from non-H variants like HERF1603G, which lack automotive qualification documentation.
How is polarity marked on the HERF1603GH package?
Polarity on the HERF1603GH is marked on the top surface of the ITO-220AB package via laser-etched symbol: a white band adjacent to Lead 1 (Anode), with the metal tab and Lead 2 (Cathode) forming the common cathode node. This marking aligns with JEDEC standard orientation for ITO-220AB devices.
