Product details
Overview
HERF1601GH from Taiwan Semiconductor is a 16A, 50V AEC-Q101-qualified high-efficiency rectifier in ITO-220AB package with dual-die configuration, 1.0V max forward voltage at 8A/25°C, 125A surge rating, and 1.5°C/W junction-to-case thermal resistance - used in automotive-grade DC-DC converters.
For engineers reviewing the HERF1601GH datasheet, HERF1601GH pinout, HERF1601GH application, or HERF1601GH equivalent, key selection factors include its AEC-Q101 qualification, 50V VRRM rating, low VF performance, ITO-220AB mechanical compatibility, and dual-die thermal design for high-current freewheeling paths.
Technical Context
This device is a single-phase, dual-die silicon rectifier optimized for switching-mode power supplies requiring low conduction loss and robust surge handling. It operates with a maximum junction temperature of 150°C and achieves 1.0V typical forward voltage per diode at 8A/25°C under pulse conditions (PW = 0.3ms).
The ITO-220AB package enables direct heatsink mounting with 0.56 N·m max torque, while its UL 94V-0 molding compound and matte tin-plated leads comply with J-STD-002 solderability and JESD 201 Class 2 whisker requirements - critical for automotive under-hood environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 50 V - Maximum repetitive reverse voltage; defines safe blocking capability in 50V-rated DC-DC stages. |
| IF | 16 A - Continuous forward current rating; supports sustained 16A output in compact converter designs. |
| IFSM | 125 A - Non-repetitive surge current (8.3ms half-sine); handles startup/load-dump transients in automotive systems. |
| VF (max) | 1.0 V @ 8A, 25°C - Low conduction loss per diode; reduces power dissipation and improves efficiency vs. standard rectifiers. |
| RθJC | 1.5 °C/W - Junction-to-case thermal resistance; enables predictable thermal design when mounted to heatsink. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-efficiency rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-16EWH05-M3 | 50V VRRM, 16A IF, TO-247AC package, VF = 0.92V typ @ 8A - lower VF but no AEC-Q101 qualification. | Used in industrial SMPS only; not approved for automotive ECUs or ADAS modules. | Select when AEC-Q101 is not required and lowest possible VF is prioritized over qualification overhead. |
| ON Semiconductor MUR1620CTG | 200V VRRM, 16A IF, TO-220AB package, VF = 1.7V max @ 8A - higher voltage rating but significantly higher conduction loss. | Suitable for universal-input PFC front-ends; over-specified for 50V automotive rails. | Select only if system requires >100V blocking margin or legacy TO-220AB footprint reuse is mandatory. |
Compared with VS-16EWH05-M3 and MUR1620CTG, HERF1601GH uniquely delivers AEC-Q101 compliance, 50V-optimized VF, and ITO-220AB thermal performance - making it the only qualified choice for space-constrained, thermally demanding automotive 12V/48V converter outputs.

FAQ
What is the peak repetitive reverse voltage rating for HERF1601GH?
The HERF1601GH has a repetitive peak reverse voltage (VRRM) rating of 50 V. This value is fixed for the HERF1601GH variant and confirmed in the absolute maximum ratings table of the official Taiwan Semiconductor datasheet (Version I2105). It defines the maximum DC or sinusoidal AC reverse voltage the device can block continuously without breakdown. Exceeding this rating risks irreversible avalanche failure.
Is HERF1601GH pin-compatible with standard TO-220AB rectifiers?
No - HERF1601GH uses the ITO-220AB package, which features an electrically isolated metal tab and different leadframe geometry versus standard TO-220AB. While both have three leads and similar outline dimensions, the ITO-220AB's isolation and thermal path require dedicated PCB layout. HERF1601GH must be mounted using its isolated tab for heatsinking, unlike conductive-tab TO-220AB devices.
Does HERF1601GH support dual-diode independent operation?
Yes - HERF1601GH integrates two independent silicon rectifier dies sharing a common cathode terminal. Anode 1 and Anode 2 are fully isolated and may be driven by separate switching nodes (e.g., in center-tapped or dual-phase topologies). The datasheet confirms dual-die configuration and specifies individual electrical parameters per diode, enabling true independent operation within one package.
What is the maximum junction temperature and how does it affect HERF1601GH derating?
The maximum junction temperature (TJ max) for HERF1601GH is 150°C. Derating begins at case temperatures above 25°C, with average forward current decreasing linearly to zero at 150°C case temperature - as shown in Figure 1 of the datasheet. At 100°C case temperature, the usable IF drops to approximately 10.5A. Proper heatsinking maintaining Tc ≤ 95°C is required to sustain full 16A rating.
How does the AEC-Q101 qualification of HERF1601GH impact its use in non-automotive applications?
The AEC-Q101 qualification of HERF1601GH provides enhanced reliability margins - including extended temperature cycling, high-temperature reverse bias, and accelerated life testing - that benefit any mission-critical application. While not required outside automotive, these qualifications translate to longer field life, improved robustness against thermal shock, and reduced infant mortality in industrial power supplies, medical auxiliary circuits, and aerospace subsystems where long-term stability is essential.
