Product details
Overview
HER1001GH from Taiwan Semiconductor is a high-efficiency, AEC-Q101 qualified dual-die ultrafast recovery rectifier in TO-220AB package, rated for 10 A average forward current, 50 V repetitive peak reverse voltage, and 125 A non-repetitive surge current - used in automotive-grade DC/DC converters and freewheeling paths where low VF (1.0 V @ 5 A, 25°C) and fast trr (≤50 ns) reduce conduction and switching losses.
For engineers reviewing the HER1001GH datasheet, HER1001GH pinout, HER1001GH application, or HER1001GH equivalent, key selection criteria include its AEC-Q101 qualification, 1.0 V forward voltage at 5 A, 50 ns reverse recovery time, TO-220AB thermal resistance (1.5 °C/W), and dual-die configuration enabling high-current single-package solutions in space-constrained power stages.
Technical Context
This device integrates two independent silicon rectifier dies in a single TO-220AB thermally optimized package, supporting parallel or common-cathode configurations. Its ultrafast recovery (trr ≤50 ns) and low junction capacitance (60 pF @ 4 V, 1 MHz) minimize switching noise and EMI in high-frequency SMPS topologies.
The HER1001GH operates across –55°C to +150°C junction temperature range with 1.5 °C/W junction-to-case thermal resistance, enabling reliable operation under sustained 10 A load without forced cooling in automotive under-hood environments.
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 |
|---|---|---|---|
| STTH10R06DJF | 600 V VRRM, 1.7 V VF @ 5 A, 60 ns trr, TO-220AC package (single die) | Higher voltage rating but higher VF and slower recovery - suited for 48 V industrial systems, not 12 V automotive | Select when 600 V blocking is required and AEC-Q101 is not mandatory |
| ON Semi MUR1050CT | 50 V VRRM, 1.25 V VF @ 5 A, 75 ns trr, TO-220AB, dual common-cathode | Non-AEC-Q101, higher VF and slower recovery - acceptable for cost-sensitive industrial converters | Choose for non-automotive applications where qualification and ultrafast performance are secondary |
Compared with STTH10R06DJF and MUR1050CT, the HER1001GH delivers lower conduction loss (1.0 V vs. ≥1.25 V), faster switching (50 ns vs. ≥60 ns), and automotive qualification - making it the only option for AEC-compliant 12 V power stages requiring <1.1 V VF and <60 ns trr.

FAQ
What is the maximum junction temperature for HER1001GH?
The HER1001GH has a maximum junction temperature (TJ MAX) of +150°C, validated across its full operating range from –55°C to +150°C. This rating enables reliable operation in automotive under-hood environments when mounted on a heatsink with thermal interface material, leveraging its 1.5 °C/W RθJC to maintain safe junction temperatures at 10 A continuous current.
Is HER1001GH pin-compatible with standard TO-220AB rectifiers?
Yes, the HER1001GH uses the standard TO-220AB outline with identical mechanical dimensions, lead spacing, and mounting hole location as industry-standard dual-diode TO-220AB rectifiers. Its pinout - Anode 1 / Common Cathode / Anode 2 - matches common-cathode dual configurations, allowing drop-in replacement where dual-die functionality and AEC-Q101 qualification are required.
Does HER1001GH support parallel operation of its two dies?
Yes, the HER1001GH integrates two electrically isolated rectifier dies sharing only the cathode terminal, enabling true parallel operation without external balancing components. Both dies exhibit matched VF and trr characteristics per datasheet, ensuring current sharing within ±5% at 10 A total load - critical for high-current automotive power rails.
What is the reverse recovery time specification for HER1001GH?
The HER1001GH has a maximum reverse recovery time (trr) of 50 ns, measured at IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A. This ultrafast recovery enables efficient operation in high-frequency switching converters up to 500 kHz while minimizing switching losses and voltage overshoot during turn-off transitions.
How does the AEC-Q101 qualification impact HER1001GH's use in automotive designs?
The AEC-Q101 qualification confirms that HER1001GH has passed rigorous stress tests including temperature cycling, mechanical shock, and high-temperature reverse bias - ensuring long-term reliability in automotive under-hood applications. This certification eliminates the need for additional qualification testing when using HER1001GH in 12 V power systems for ADAS, infotainment, or body control modules.
