Product details
Overview
HER1601GH from Taiwan Semiconductor is a high-efficiency, AEC-Q101-qualified dual-die ultrafast recovery rectifier in TO-220AB package, rated for 16 A average forward current, 50 V repetitive peak reverse voltage, and 125 A surge current. It delivers low forward voltage (1.0 V at 8 A, 25°C), 50 ns reverse recovery time, and 80 pF junction capacitance per diode - optimized for DC/DC converters and freewheeling paths in automotive-grade power supplies.
For engineers reviewing the HER1601GH datasheet, HER1601GH pinout, HER1601GH application, or HER1601GH equivalent, key selection criteria include its AEC-Q101 qualification, TO-220AB thermal performance (RθJC = 1.5°C/W), 50 V VRRM rating, dual-die configuration, and verified 150°C maximum junction temperature.
Technical Context
This device integrates two independent ultrafast recovery diodes in a single TO-220AB package with common cathode configuration. Its 50 ns trr and low VF enable high-frequency switching efficiency in hard-switched topologies, while the 1.5°C/W junction-to-case thermal resistance supports direct heatsink mounting without thermal derating penalties up to 16 A continuous conduction.
The HER1601GH meets JESD201 Class 2 whisker resistance and RoHS/halogen-free requirements, with matte tin-plated leads solderable per J-STD-002. Its 50 V VRRM and 125 A IFSM make it suitable for low-voltage, high-current freewheeling and output rectification where fast recovery and low conduction loss are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 50 V - Maximum non-repetitive reverse blocking voltage; defines safe operating range in low-voltage DC/DC outputs. |
| IF | 16 A - Continuous average forward current at case temperature ≤ 75°C; enables compact 12–24 V system designs. |
| IFSM | 125 A - Peak non-repetitive surge current (8.3 ms half-sine); withstands inrush and fault transients without failure. |
| VF | 1.0 V @ 8 A, 25°C - Low conduction loss reduces heat generation and improves system efficiency in high-duty-cycle operation. |
| trr | 50 ns - Ultrafast reverse recovery minimizes switching losses and EMI in 100–500 kHz SMPS designs. |
| RθJC | 1.5°C/W - Enables direct heatsink mounting with predictable thermal rise; supports >10 W dissipation at <30°C ΔT. |
| Junction Temp | −55°C to +150°C - Wide operating range validated for under-hood automotive environments and industrial enclosures. |
Pinout & Package
TO-220AB package with three terminals: Anode 1, Anode 2, and common Cathode. Mounting hole centered on tab; tab is electrically connected to cathode. Matte tin-plated leads meet J-STD-002 solderability; max mounting torque 0.56 N·m.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode 1 | Input terminal for first diode | Accepts positive input during forward conduction; isolated from Anode 2 for dual-path operation. |
| Anode 2 | Input terminal for second diode | Enables parallel or interleaved conduction; same electrical characteristics as Anode 1. |
| Cathode (Tab) | Common output node | Electrically tied to metal tab; requires insulated mounting if referenced to non-ground potential. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive powertrain and chassis applications per stress test requirements including HTOL, TC, and UHAST. |
| Dual-die configuration | Two matched ultrafast diodes in one TO-220AB footprint - saves PCB area vs. discrete dual-diode solutions. |
| Ultrafast recovery (50 ns) | Reduces turn-off switching loss and associated EMI in high-frequency converters (>200 kHz). |
| Low RθJC (1.5°C/W) | Permits direct heatsink attachment with minimal thermal interface resistance; simplifies thermal design. |
| Halogen-free & RoHS compliant | Meets IEC 61249-2-21 and EU RoHS Directive 2011/65/EU - supports green manufacturing and end-of-life compliance. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultrafast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1605D | 50 V VRRM, 16 A IF, 55 ns trr, TO-220AC package (single anode) | Single-diode configuration; no dual-anode option for interleaved paths | Select when only one rectification path is needed and space permits separate devices. |
| ON Semiconductor MUR1620CT | 200 V VRRM, 16 A IF, 60 ns trr, TO-220AB dual common-cathode | Higher VRRM sacrifices some VF efficiency; not AEC-Q101 qualified | Choose for higher-voltage margin in non-automotive 24–48 V systems where qualification is not required. |
Compared with STTH1605D and MUR1620CT, the HER1601GH uniquely combines AEC-Q101 qualification, 50 V optimization for low-VF efficiency, and dual-anode flexibility - making it the preferred choice for space-constrained, automotive-grade 12–24 V power conversion where reliability and thermal performance are prioritized.

FAQ
Is HER1601GH AEC-Q101 qualified?
Yes, the "H" suffix in HER1601GH explicitly denotes AEC-Q101 qualification per the manufacturer's ordering information. This includes stress testing for high-temperature operating life, temperature cycling, and unbiased highly accelerated stress testing - confirming suitability for automotive power electronics applications such as body control modules and ADAS power supplies.
What is the pin configuration of HER1601GH?
The HER1601GH uses a TO-220AB package with three terminals: Anode 1, Anode 2, and a common Cathode connected to the metal tab. The tab is electrically active and must be electrically isolated from the heatsink unless referenced to cathode potential. Pinout is confirmed in the official TSC package outline diagram and mechanical data sheet.
How does HER1601GH differ from HER1602GH?
The HER1601GH and HER1602GH share identical package, current ratings (16 A IF, 125 A IFSM), and thermal specs, but differ in repetitive peak reverse voltage: HER1601GH is rated for 50 V VRRM, while HER1602GH is rated for 100 V VRRM. Forward voltage and reverse recovery time also vary slightly due to process tuning for each voltage grade.
Can HER1601GH replace standard FRD rectifiers in existing designs?
Yes, HER1601GH can directly replace standard fast recovery diodes (e.g., FEP16DT, UF1605) in TO-220AB footprints, provided the 50 V VRRM meets system reverse voltage requirements. Its lower VF (1.0 V) and faster trr (50 ns) reduce conduction and switching losses, improving efficiency - especially in high-frequency, high-duty-cycle applications.
What is the maximum junction temperature for HER1601GH?
The HER1601GH has a maximum junction temperature (TJ) of +150°C, as specified in the Absolute Maximum Ratings table. This rating is maintained across the full operating ambient range (−55°C to +150°C storage), and thermal design must ensure junction temperature remains within this limit using the published RθJC = 1.5°C/W and appropriate heatsinking.
