Product details
Overview
HERF1602GH from Taiwan Semiconductor is a 16A, 100V AEC-Q101-qualified high-efficiency rectifier diode in ITO-220AB package with dual-die configuration, low 1.0V 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 and switching inverters.
For engineers reviewing the HERF1602GH datasheet, HERF1602GH pinout, HERF1602GH application, or HERF1602GH equivalent, key selection criteria include its AEC-Q101 qualification, 100V VRRM rating, 1.0V VF at 8A, 50ns reverse recovery time, and ITO-220AB mechanical compatibility with heatsink mounting.
Technical Context
This device is a single-phase, dual-die silicon rectifier optimized for high-current, high-reliability power conversion. It delivers 16A average forward current with 125A non-repetitive surge capability and operates up to +150°C junction temperature.
Its 100V repetitive peak reverse voltage (VRRM), 70V RMS reverse voltage (VR(RMS)), and 50ns trr support fast-switching topologies. The 1.5°C/W RθJC enables efficient thermal management in constrained automotive and industrial power modules.

FAQ
What is the peak repetitive reverse voltage rating of HERF1602GH?
The HERF1602GH has a repetitive peak reverse voltage (VRRM) rating of 100 V, verified per the official Taiwan Semiconductor datasheet Version I2105. This value defines the maximum reverse-biased voltage the device can block repeatedly without breakdown and is strictly validated for the HERF1602GH variant-not extrapolated from adjacent family members like HERF1601G or HERF1603G.
Is HERF1602GH qualified for automotive applications?
Yes, HERF1602GH is explicitly AEC-Q101 qualified, as confirmed by the "H" suffix in its ordering code and documented in the Taiwan Semiconductor datasheet. This qualification covers stress tests including high-temperature operating life, temperature cycling, and unbiased highly accelerated stress testing-making HERF1602GH suitable for under-hood automotive power modules and ADAS subsystems.
What is the forward voltage drop of HERF1602GH at rated current?
The HERF1602GH exhibits a typical forward voltage (VF) of 1.0 V at 8 A and 25°C junction temperature, per the Electrical Specifications table in the official datasheet. This value is measured per diode in the dual-die configuration and reflects low conduction loss essential for high-efficiency power conversion stages.
Does HERF1602GH have an electrically isolated package?
Yes, HERF1602GH uses the ITO-220AB package, where the metal tab is electrically isolated from both anode and cathode terminals. This isolation-confirmed in the Mechanical Data section-is critical for direct heatsink mounting without additional insulating hardware in high-voltage applications.
What is the maximum junction temperature for HERF1602GH?
The maximum junction temperature (TJ max) for HERF1602GH is +150°C, as specified in the Absolute Maximum Ratings table. This rating applies across the full operating range and enables deployment in high-ambient environments such as engine compartments and enclosed industrial enclosures without derating below 16A.
