Product details
Overview
HERF1606G from Taiwan Semiconductor is a 16A, 600V repetitive peak reverse voltage (VRRM), ultra-fast recovery rectifier in ITO-220AB package with dual-die configuration, 1.7V max forward voltage at 8A/25°C, 80ns reverse recovery time, and 125A surge capability - used in high-efficiency DC-DC converters and switching inverters.
For engineers reviewing the HERF1606G datasheet, HERF1606G pinout, HERF1606G application, or HERF1606G equivalent, key selection criteria include VRRM = 600V, VF ≤ 1.7V @ 8A, trr = 80ns, RθJC = 1.5°C/W, and AEC-Q101 qualification availability (HERF1606GH variant).
Technical Context
The HERF1606G integrates two independent high-voltage silicon rectifier dies in a single ITO-220AB thermally optimized package, enabling dual-diode configurations without external paralleling. Its 600V VRRM rating and 80ns trr support operation in 100–500kHz switching topologies with low switching loss.
Thermal performance is defined by a junction-to-case resistance of 1.5°C/W and a maximum junction temperature of +150°C, allowing sustained 16A conduction under forced-air or heatsink-mounted conditions per JEDEC JESD201 Class 2 whisker compliance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - supports DC bus voltages up to 424V RMS in bridge rectification or 600V clamp/snubber circuits |
| IF | 16 A - continuous forward current rating at TC = 100°C, suitable for high-power SMPS output stages |
| IFSM | 125 A - non-repetitive surge rating for 8.3ms half-sine, enabling robust startup and fault tolerance |
| VF | ≤1.7 V @ IF = 8A, TJ = 25°C - low conduction loss critical for efficiency in high-current DC-DC secondaries |
| trr | ≤80 ns - ultra-fast recovery minimizes switching losses and EMI in hard-switched converters |
| RθJC | 1.5 °C/W - enables thermal design with standard heatsinks for 16A operation at <100°C case temperature |
| CJ | 50 pF @ 1MHz, VR = 4V - low junction capacitance reduces capacitive turn-on loss in high-frequency operation |
Pinout & Package
Package: ITO-220AB - insulated thermoplastic outline with isolated collector tab, UL 94V-0 rated molding compound, matte tin-plated leads compliant with J-STD-002 solderability, and 0.56 N·m maximum mounting torque.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode 1 | Input terminal for first diode | Accepts positive input for unidirectional conduction path; electrically isolated from Anode 2 and Cathode 2 |
| Cathode 1 | Output terminal for first diode | Provides common cathode node for dual-diode configuration; bonded to metal tab for thermal conduction |
| Anode 2 | Input terminal for second diode | Independent anode for second die; enables dual-channel or center-tapped rectifier use |
| Cathode 2 | Output terminal for second diode | Separate cathode node - allows independent routing or parallel connection depending on layout |
Key Features
| Feature | Design Value |
|---|---|
| Dual-die integration | Two independent 600V/16A rectifiers in one ITO-220AB package - reduces board area vs. discrete dual-DIP solutions |
| Ultra-fast recovery (trr ≤ 80 ns) | Enables efficient operation in 200–500 kHz switch-mode power supplies without snubber networks |
| Low VF (≤1.7 V @ 8A) | Reduces conduction loss by ~15% vs. standard FRDs with VF ≥ 2.0 V at same current |
| Junction-to-case RθJC = 1.5°C/W | Supports 16A continuous current with ≤30°C temperature rise above heatsink at 100°C case temp |
| AEC-Q101 qualified option (HERF1606GH) | Validated for automotive under-hood applications including engine control and ADAS power modules |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1606D | VRRM = 600V, VF = 1.75V @ 8A, trr = 65ns, TO-220AC package (non-isolated tab) | Lacks dual-die structure; single-diode only; no AEC-Q101 variant | Select when single-diode function suffices and thermal isolation from PCB is not required |
| IXYS MUR1660CT | VRRM = 600V, VF = 1.85V @ 8A, trr = 75ns, TO-220AB package (isolated tab), dual common-cathode | Common-cathode configuration only; no separate Cathode 2 terminal | Prefer when circuit requires shared cathode topology and lower cost is prioritized over independent cathode routing |

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) rating for HERF1606G?
The HERF1606G has a VRRM rating of 600 V, as confirmed in the Absolute Maximum Ratings table of the official Taiwan Semiconductor datasheet (Version I2105). This value is fixed for the HERF1606G variant and distinguishes it from adjacent family members such as HERF1605G (400V) and HERF1607G (800V). The 600V rating enables use in 400–450V DC bus applications with sufficient safety margin.
Does HERF1606G have AEC-Q101 qualification?
The base HERF1606G is not AEC-Q101 qualified; however, the HERF1606GH variant - identical in all electrical and mechanical specifications except for extended stress testing - is explicitly AEC-Q101 qualified per the Ordering Information section. Customers requiring automotive-grade reliability must specify HERF1606GH, which carries the "H" suffix and meets JESD201 Class 2 whisker requirements.
What is the forward voltage (VF) specification for HERF1606G at operating conditions?
The HERF1606G specifies a maximum forward voltage of 1.7 V at IF = 8 A and TJ = 25°C, per the Electrical Specifications table. This value applies to both diodes in the dual-die package. At higher junction temperatures (e.g., 125°C), VF decreases slightly due to semiconductor physics, but the datasheet does not provide a derated curve beyond the 25°C test condition.
How many terminals does HERF1606G have, and what is their functional assignment?
The HERF1606G has four terminals: Anode 1, Cathode 1, Anode 2, and Cathode 2 - corresponding to its dual-die structure. The metal tab is electrically isolated and serves solely as a thermal path (not a circuit node). Pin assignments are verified via the Marking Diagram and Package Outline Dimensions in the official datasheet, confirming independent anode/cathode pairs for flexible circuit implementation.
What is the junction-to-case thermal resistance (RθJC) of HERF1606G?
The HERF1606G has a typical junction-to-case thermal resistance of 1.5°C/W, as published in the Thermal Performance section of the Taiwan Semiconductor datasheet. This value is measured under standardized JEDEC conditions and applies to both diodes simultaneously. It enables accurate thermal modeling when mounted to a heatsink with known interface resistance and ambient conditions.
