Product details
Overview
HER206G-T from Taiwan Semiconductor is a 2A, 600V fast recovery rectifier diode in DO-204AC (DO-15) package, featuring 1.7V forward voltage at 2A and 75ns reverse recovery time. It delivers high surge current capability (60A), low power loss, and operates up to 150°C junction temperature - used in high-voltage DC-DC converters and switching inverters.
For engineers reviewing the HER206G-T datasheet, HER206G-T pinout, HER206G-T application, or HER206G-T equivalent, key selection criteria include VRRM=600V, trr=75ns, VF=1.7V @2A, IFSM=60A, and DO-204AC mechanical compatibility with standard through-hole layouts.
Technical Context
This single-die fast recovery rectifier uses glass-passivated junction technology for stable performance under repetitive surge stress. Its 600V VRRM rating and 75ns trr enable efficient operation in high-frequency switching topologies where reverse recovery losses must be minimized.
The device exhibits 20pF junction capacitance at 1MHz/4V and 150µA reverse leakage at 125°C, supporting reliable blocking in high-temperature industrial power supplies. Thermal resistance RθJA is 60°C/W, consistent with DO-204AC package limitations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - Maximum repetitive reverse voltage before breakdown; defines safe operating ceiling in high-voltage DC bus applications |
| IF | 2 A - Continuous average forward current; sets steady-state conduction capacity in power supply output stages |
| trr | 75 ns - Reverse recovery time at IF=0.5A, IR=1.0A, Irr=0.25A; determines switching loss and EMI in 50–200 kHz SMPS |
| VF | 1.7 V @ 2A, 25°C - Forward voltage drop; directly impacts conduction loss and thermal design in rectifier legs |
| IFSM | 60 A - Non-repetitive peak surge current (8.3ms half-sine); supports cold-start and fault-current robustness |
| TJ max | 150 °C - Maximum junction temperature; enables operation in enclosed industrial enclosures without forced cooling |
| CJ | 20 pF @ 1MHz, VR=4V - Junction capacitance; affects high-frequency turn-off behavior and snubber design |
Pinout & Package
DO-204AC (DO-15) axial-leaded package with cathode band marking. Leads are pure tin-plated, solderable per J-STD-002, and meet JESD 201 Class 1A whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to lower-potential side (e.g., transformer secondary center-tap or switch node return) |
| Cathode | Forward current exit / reverse blocking terminal | Marked by band; ties to output rail or filter capacitor positive; blocks 600V reverse during off-state |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated chip junction | Enhances humidity resistance and long-term reliability in unsealed industrial environments |
| Low VF = 1.7V @ 2A | Reduces conduction loss by ~15% vs. standard FRDs with VF > 1.9V at same current |
| trr = 75ns | Enables use in 100–200 kHz SMPS without excessive switching loss or gate drive stress on MOSFETs |
| RoHS + halogen-free | Complies with IEC 61249-2-21; suitable for export-sensitive consumer and industrial end equipment |
| 60A IFSM rating | Withstands 30× rated current surge, supporting inrush limiting in offline AC-DC front-ends |
Applications
| High-Voltage DC-DC Converters | Switching Inverters |
|---|---|
Use Scenario: Secondary-side rectification in isolated 400V–600V bus DC-DC converters for telecom and server PSUs. IC Role / Device Role / Timing Role: Fast recovery rectifier handling 2A continuous output current with minimal reverse recovery loss. Use Value: 600V VRRM and 75ns trr prevent voltage overshoot and reduce snubber size versus slower 600V rectifiers. | Use Scenario: Output stage freewheeling path in three-phase motor drive inverters with 600V DC link. IC Role / Device Role / Timing Role: Freewheeling diode clamping inductive kickback during IGBT turn-off.

IC Role / Device Role / Timing Role: Bidirectional conduction path during battery-to-AC inversion and AC-to-battery charging cycles. Use Value: 150°C TJ and 60A IFSM support sustained overload and battery short-circuit protection events. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar fast recovery rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH2R06 | VRRM=600V, trr=65ns, VF=1.7V @2A, DO-204AC, but higher IR (200µA @125°C) | Slightly faster recovery but higher leakage; less suitable for high-temp standby modes | Prefer HER206G-T where low IR is critical in thermally constrained enclosures |
| ES2J | VRRM=600V, trr=35ns, VF=1.7V @2A, SMD SMB package - not pin-compatible | Surface-mount alternative requiring PCB redesign; better for automated assembly | Select ES2J only when transitioning to SMT; HER206G-T remains optimal for through-hole legacy designs |
Compared with STTH2R06 and ES2J, HER206G-T offers balanced trr/VF/IR trade-offs in DO-204AC, making it ideal for cost-sensitive, thermally demanding through-hole power supplies where leakage and package compatibility are decisive.

FAQ
What is the maximum junction temperature rating for HER206G-T?
The HER206G-T has a maximum junction temperature (TJ) of +150°C, verified per absolute maximum ratings table. This allows HER206G-T to operate reliably in sealed enclosures or near heat-generating components without derating below 2A up to ambient temperatures of 80°C, assuming standard DO-204AC board-level thermal conditions.
Does HER206G-T have a RoHS-compliant and halogen-free construction?
Yes, HER206G-T is RoHS compliant and halogen-free per IEC 61249-2-21. The molding compound meets UL 94V-0 flammability rating, and the pure tin-plated leads satisfy J-STD-002 solderability requirements - all confirmed in the official Taiwan Semiconductor datasheet revision B2105.
What is the reverse recovery time (trr) specification for HER206G-T?
The HER206G-T reverse recovery time is 75ns, measured under IF = 0.5A, IR = 1.0A, and Irr = 0.25A conditions. This value is specified in the Electrical Specifications table and validated across production lots - critical for minimizing switching loss in 100–200 kHz power converters using HER206G-T.
Is HER206G-T compatible with lead-free reflow soldering processes?
HER206G-T is designed for wave and hand soldering per J-STD-002, and its pure tin-plated leads support lead-free wave soldering. While not rated for standard Pb-free reflow (due to axial DO-204AC geometry), HER206G-T can withstand peak temperatures up to 260°C for 10 seconds - sufficient for selective reflow or post-assembly attachment.
How does the forward voltage of HER206G-T compare to lower-voltage variants like HER201G-T?
HER206G-T has a typical VF of 1.7V at 2A and 25°C, while HER201G-T is rated at 1.0V under identical conditions. This increase reflects higher doping gradients and wider depletion regions needed to sustain 600V blocking - a fundamental trade-off confirmed across the HER20xG-T family datasheet.
