Product details
Overview
HERF1603G from Taiwan Semiconductor is a 16A, 200V repetitive peak reverse voltage (VRRM) high-efficiency fast recovery rectifier in ITO-220AB package with dual-die configuration, 1.5°C/W junction-to-case thermal resistance, and 50ns reverse recovery time (trr), used in DC-DC converters and freewheeling paths.
For engineers reviewing the HERF1603G datasheet, HERF1603G pinout, HERF1603G application, or HERF1603G equivalent, key selection criteria include VRRM = 200V, IF = 16A, VF ≤ 1.0V at 8A/25°C, trr ≤ 50ns, and ITO-220AB mechanical compatibility with heatsink mounting.
Technical Context
This device integrates two independent silicon rectifier dies in a single ITO-220AB thermally optimized package, enabling dual-path or common-cathode configurations. Its 50ns trr and low VF support high-frequency switching up to 100kHz in SMPS topologies while maintaining low conduction and switching losses.
The HERF1603G operates across -55°C to +150°C junction temperature range, with 125A non-repetitive surge rating (IFSM) and UL Recognized File #E-326243 compliance. It meets JESD201 Class 2 whisker resistance and RoHS/halogen-free requirements per IEC 61249-2-21.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - Maximum repetitive reverse blocking voltage; defines usable input voltage range in bridge/freewheeling applications |
| IF | 16 A - Continuous forward current rating at TC = 100°C; determines heatsink sizing for steady-state operation |
| IFSM | 125 A - Peak non-repetitive surge current (8.3ms half-sine); supports inrush and transient overload handling |
| trr | 50 ns - Reverse recovery time at IF = 0.5A, IR = 1.0A, Irr = 0.25A; enables efficient operation in 50–100 kHz SMPS |
| VF | ≤1.0 V - Forward voltage drop per diode at IF = 8A, TJ = 25°C; directly impacts conduction loss and thermal design |
| RθJC | 1.5 °C/W - Junction-to-case thermal resistance; enables direct thermal interface to heatsink without isolation pad penalty |
| CJ | 80 pF - Junction capacitance per diode at 1MHz, VR = 4V; affects high-frequency noise and EMI filter design |
Pinout & Package
ITO-220AB package with three terminals: Anode 1, Cathode (common), Anode 2 - configured as dual independent diodes sharing cathode connection. Matte tin-plated leads meet J-STD-002 solderability; mounting torque ≤ 0.56 N·m.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode 1 | Input terminal for first diode | Accepts positive voltage source in freewheeling or half-bridge leg; electrically isolated from Anode 2 |
| Cathode | Common output node | Shared cathode connection enables dual-anode, single-output configuration; primary thermal path to case |
| Anode 2 | Input terminal for second diode | Enables independent current path routing; allows interleaved or phase-split operation in multi-phase converters |
Key Features
| Feature | Design Value |
|---|---|
| Dual-die integration in ITO-220AB | Reduces board space vs. two discrete TO-220 devices; maintains same footprint while doubling functional density |
| 50 ns reverse recovery time | Minimizes switching loss and di/dt-induced voltage spikes in hard-switched 60–100 kHz converters |
| 1.0 V max forward voltage at 8A | Lowers conduction loss by ~15% vs. standard FRDs with VF ≥ 1.15V, improving efficiency in 12–48V output rails |
| UL Recognized (E-326243) | Validates safety compliance for end-equipment certification without additional system-level testing overhead |
| Junction temp range: –55°C to +150°C | Supports under-hood automotive and industrial ambient conditions without derating below –40°C ambient |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-efficiency rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1602CW | VRRM = 200V, IF = 16A, trr = 45ns, VF = 1.05V @ 8A, TO-247AC package | Single-diode TO-247AC; requires two devices for dual-path use; higher RθJC (1.8°C/W) | Preferred where PCB layout allows separate devices and lower trr is prioritized over thermal density |
| IXYS MBR16200CT | VRRM = 200V, IF = 16A, VF = 0.95V @ 8A, trr = 60ns, TO-220AB package | Common-cathode Schottky; lower VF but limited to TJ ≤ 125°C; not AEC-Q101 qualified | Selected for ultra-low VF needs in non-automotive, <100°C ambient environments |
Compared with STTH1602CW and MBR16200CT, the HERF1603G delivers superior thermal density (1.5°C/W) and automotive qualification path (via HERF1603GH), while balancing VF, trr, and ruggedness for cost-sensitive industrial and EV auxiliary power designs.

FAQ
What is the maximum junction temperature rating for the HERF1603G?
The HERF1603G has a maximum junction temperature (TJ MAX) of +150°C, with operational capability from –55°C to +150°C. This rating allows reliable use in under-hood automotive environments and high-ambient industrial enclosures when mounted on an appropriately sized heatsink per its 1.5°C/W RθJC specification. The HERF1603G must be derated linearly above TC = 100°C per the forward current derating curve in the datasheet.
Is the HERF1603G pin-compatible with other devices in the HERF160xG family?
Yes, all HERF1601G through HERF1608G share identical ITO-220AB packaging, pinout, and terminal configuration - Anode 1, Cathode (common), Anode 2 - enabling drop-in replacement across the voltage range (50V to 1000V VRRM). Only the VRRM, VF, CJ, and trr values differ between variants; thermal and mechanical design remains unchanged for HERF1603G and siblings.
Does the HERF1603G support automotive qualification?
The HERF1603G itself is not AEC-Q101 qualified, but its variant HERF1603GH is explicitly listed as AEC-Q101 qualified in the ordering information. Customers requiring automotive-grade reliability must specify HERF1603GH - same electrical specs and package as HERF1603G, with added stress test validation per AEC-Q101 Rev D.
What is the reverse recovery time (trr) specification for the HERF1603G?
The HERF1603G has a maximum reverse recovery time (trr) of 50 ns, measured under conditions IF = 0.5A, IR = 1.0A, and Irr = 0.25A. This value is confirmed in the Electrical Specifications table for HERF1601G–HERF1605G group and applies directly to HERF1603G. It enables efficient operation in hard-switched converters up to 100 kHz without excessive switching loss or ringing.
How does the HERF1603G compare to standard FRD alternatives in terms of thermal performance?
The HERF1603G achieves a junction-to-case thermal resistance (RθJC) of 1.5°C/W - significantly lower than typical FRDs in TO-220AB (often ≥2.0°C/W). This 0.5°C/W improvement reduces die temperature rise by ~8°C at 16A, extending lifetime and allowing smaller heatsinks. Its ITO-220AB package also features matte tin-plated leads and UL 94V-0 molding compound, enhancing manufacturability and safety margin.
