Product details
Overview
HER206GH from Taiwan Semiconductor is a high-efficiency, AEC-Q101-qualified ultrafast recovery rectifier diode in DO-204AC (DO-15) package, rated for 2 A average forward current, 600 V repetitive peak reverse voltage, and 75 ns reverse recovery time - used in automotive DC-DC converters and switching power supplies.
For engineers reviewing the HER206GH datasheet, HER206GH pinout, HER206GH application, or HER206GH equivalent, key selection criteria include its 600 V VRRM, 75 ns trr, 1.7 V typical VF at 2 A, AEC-Q101 qualification, and DO-15 mechanical compatibility with legacy through-hole layouts.
Technical Context
The HER206GH employs a glass-passivated single-die silicon junction optimized for fast switching in high-frequency SMPS topologies. Its 75 ns reverse recovery time and low 20 pF junction capacitance minimize switching losses during turn-off transitions in 50–500 kHz converters.
Designed for automotive-grade reliability, it supports continuous operation up to +150 °C junction temperature and withstands 60 A non-repetitive surge current (8.3 ms half-sine), making it suitable for transient-heavy freewheeling and output rectification roles in engine control units and ADAS power stages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - blocks up to 600 V reverse voltage without breakdown, enabling use in 48 V automotive systems with 2× safety margin |
| IF | 2 A average - delivers sustained 2 A DC output current in continuous conduction mode converters |
| trr | 75 ns - reduces switching loss and EMI in high-frequency (>100 kHz) flyback and forward converters |
| VF | 1.7 V typ @ 2 A, 25°C - lowers conduction loss vs. standard rectifiers, improving efficiency in 12–48 V outputs |
| CJ | 20 pF @ 1 MHz, 4 V - minimizes capacitive coupling and ringing in high-dV/dt switching nodes |
| TJ max | +150 °C - supports under-hood deployment without derating in ambient temperatures up to +105 °C |
| IFSM | 60 A - handles cold-crank surges and load dump transients in automotive power rails |
Pinout & Package
HER206GH uses the DO-204AC (DO-15) axial-leaded package with cathode indicated by a band on the body. Leads are pure tin-plated and solderable per J-STD-002.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unbanded end) | Forward current entry point | Connects to lower-potential side (e.g., transformer secondary center-tap or switch node return) |
| Cathode (banded end) | Forward current exit / reverse blocking terminal | Connects to output rail or positive bus; blocks reverse voltage up to 600 V |

| Glass-passivated junction | Enhances moisture resistance and long-term reliability in humid or thermally cycled environments |
| Ultrafast recovery (75 ns) | Reduces switching loss and improves efficiency over standard rectifiers in >100 kHz converters |
| Low VF (1.7 V) | Lowers conduction loss by ~15% vs. comparable 600 V rectifiers, reducing thermal stress on heatsinks |
| Halogen-free & RoHS compliant | Meets IEC 61249-2-21 and EU RoHS Directive for environmentally regulated production |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultrafast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH2R06 | Same 600 V VRRM, 2 A IF, but 50 ns trr; TO-220AC package (not DO-15) | Requires PCB layout change; better for higher-power heatsinked designs | Choose when faster recovery and thermal performance outweigh footprint constraints |
| ES2J | 600 V VRRM, 2 A IF, 35 ns trr, but not AEC-Q101 qualified; SMA package | Suitable for commercial-grade SMPS only; no automotive qualification | Choose for cost-sensitive non-automotive applications where AEC-Q101 is not required |
Compared with STTH2R06 and ES2J, the HER206GH uniquely combines AEC-Q101 qualification, DO-15 through-hole compatibility, and 75 ns recovery - making it optimal for space-constrained, automotive-compliant rectification where drop-in replacement and thermal robustness are critical.

FAQ
What is the maximum junction temperature rating for HER206GH?
The HER206GH has a maximum junction temperature (TJ) of +150 °C, allowing uninterrupted operation in under-hood automotive environments and sealed industrial enclosures. This rating is validated per JEDEC standards and enables full 2 A current capability at ambient temperatures up to +105 °C with appropriate PCB copper area. HER206GH must be mounted with adequate thermal relief to maintain this limit.
Is HER206GH pin-compatible with other HER20xG variants?
Yes, all HER20xG and HER20xGH parts share identical DO-204AC (DO-15) packaging, anode/cathode polarity marking, and lead dimensions - making HER206GH mechanically interchangeable with HER201GH through HER208GH. However, electrical parameters differ: HER206GH is rated for 600 V VRRM, while HER205GH is 400 V and HER207GH is 800 V. Substitution requires voltage margin verification.
What does the "H" suffix in HER206GH signify?
The "H" suffix in HER206GH indicates full AEC-Q101 qualification - meaning the device has passed stress tests for temperature cycling, humidity bias, high-temperature operating life, and mechanical shock per the AEC automotive reliability standard. This distinguishes HER206GH from the non-H variant (HER206G), which lacks formal automotive qualification documentation.
What is the typical forward voltage of HER206GH at rated current?
The typical forward voltage (VF) of HER206GH is 1.7 V at 2 A forward current and 25 °C junction temperature, measured under pulsed conditions (PW = 0.3 ms). At elevated temperatures (e.g., 125 °C), VF decreases slightly (~1.55 V), reducing conduction loss in thermally demanding applications. HER206GH's VF is confirmed in the official TSC G2105 datasheet.
Does HER206GH require a heatsink in standard 2 A operation?
HER206GH does not require an external heatsink for 2 A DC operation at ambient temperatures ≤ 50 °C with ≥ 1 cm² of 2-oz copper on both sides of a standard FR-4 PCB. Its RθJA is 60 °C/W, so junction rise is ~120 °C above ambient at full load - staying within the +150 °C limit. For sustained 2 A operation above 50 °C ambient or in enclosed spaces, additional copper or airflow is recommended to keep HER206GH within spec.
