Product details
Overview
HER605GH from Taiwan Semiconductor is a high-efficiency, AEC-Q101 qualified glass-passivated silicon rectifier diode in R-6 package, rated for 400 V repetitive peak reverse voltage (VRRM), 6 A average forward current (IF), and 150 A non-repetitive surge current (IFSM). It delivers low forward voltage drop (VF = 1.3 V at 6 A, 25°C) and fast reverse recovery time (trr = 50 ns), making it suitable for high-frequency switching power supplies.
For engineers reviewing the HER605GH datasheet, HER605GH pinout, HER605GH application, or HER605GH equivalent, key selection criteria include its AEC-Q101 qualification, 400 V VRRM rating, 1.3 V VF at full load, 50 ns trr, and R-6 through-hole package compatibility with industrial and automotive DC/DC converters.
Technical Context
This device is a single-die, standard recovery rectifier optimized for high-efficiency switching-mode power conversion. Its glass-passivated junction ensures stable operation up to 150°C junction temperature, while the pure tin-plated leads meet J-STD-002 solderability and JESD201 Class 2 whisker resistance requirements.
The HER605GH operates with a typical junction capacitance of 80 pF at 4.0 V reverse bias and 1 MHz, and exhibits reverse leakage of ≤10 µA at 25°C and ≤200 µA at 125°C - critical parameters for minimizing standby loss and thermal drift in high-reliability power stages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 400 V - supports input rectification in 28 V–48 V nominal bus systems with 2× safety margin against transients |
| IF | 6 A continuous - enables compact heatsink design in 100–300 W SMPS outputs |
| VF @ 6 A, 25°C | 1.3 V - reduces conduction loss to ~7.8 W per diode, improving efficiency over legacy 1N54xx series |
| trr | 50 ns - limits switching loss and EMI generation in 100–500 kHz converters |
| RθJA | 37 °C/W - allows 2.5 W dissipation with ≤92°C rise above 25°C ambient, supporting natural-convection cooling |
| AEC-Q101 | Qualified - validated for automotive under-hood applications per stress test requirements (HTOL, TC, HTRB, etc.) |
| Package | R-6 - industry-standard axial-leaded package with 1.65 g mass, UL 94V-0 molding, cathode band polarity marking |
Pinout & Package
R-6 package: axial-leaded, cylindrical epoxy body, cathode indicated by black band; lead spacing 10.16 mm (0.4"), body diameter 5.2 mm, length 10.2 mm; RoHS-compliant, halogen-free, pure tin plating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unbanded end) | Forward current entry point | Connected to transformer secondary or switch node; must withstand 150 A surge without bond wire failure |
| Cathode (banded end) | Forward current exit / reverse blocking terminal | Connected to output capacitor or ground return; reverse voltage rating applies across this terminal pair |
Key Features
| Feature | Design Value |
|---|---|

| Low VF (1.3 V @ 6 A) | Reduces conduction loss by ≥15% vs. comparable 1N5408 (1.5 V), directly improving system efficiency and thermal margin |
| Fast trr (50 ns) | Minimizes reverse recovery charge (Qrr), lowering switching losses and enabling higher-frequency operation than general-purpose rectifiers |
| AEC-Q101 qualification | Validates suitability for automotive power modules, infotainment DC/DC, and ADAS subsystems requiring zero-defect reliability |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-efficiency rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH6L06S | 600 V VRRM, 1.55 V VF @ 6 A, TO-220AC package, no AEC-Q101 | Higher voltage margin but higher conduction loss; requires PCB mount and heatsinking | Prefer when >400 V transient immunity is required and board space permits surface-mount heatsink integration |
| ON Semi MUR640CT | 400 V VRRM, dual common-cathode configuration, 1.5 V VF @ 6 A, TO-220AB | Dual-diode layout enables center-tapped transformer designs; not AEC-Q101 qualified | Select for cost-sensitive industrial PSUs needing dual-output rectification, not automotive use |
Compared with STTH6L06S and MUR640CT, the HER605GH uniquely combines AEC-Q101 qualification, axial R-6 through-hole compatibility, and 1.3 V VF - delivering automotive-grade reliability without sacrificing efficiency or requiring redesign of existing through-hole layouts.

FAQ
What is the maximum junction temperature rating for HER605GH?
The HER605GH has a maximum junction temperature (TJ MAX) of +150°C, verified per AEC-Q101 stress testing. This rating enables reliable operation in under-hood automotive environments and high-ambient industrial settings. Derating curves in the official datasheet show usable current drops linearly above 25°C ambient, maintaining safe operation up to the 150°C limit. HER605GH's glass-passivated junction contributes to thermal stability at elevated temperatures.
Is HER605GH pin-compatible with standard R-6 rectifiers like 1N5408?
Yes, HER605GH uses the standard R-6 axial package with identical mechanical dimensions, lead spacing (10.16 mm), and cathode band polarity marking as 1N5408 and other legacy R-6 rectifiers. No PCB layout change is needed for drop-in replacement. However, HER605GH offers significantly lower VF (1.3 V vs. 1.5 V) and faster trr (50 ns vs. >200 ns), improving efficiency and EMI performance without altering footprint.
Does HER605GH meet halogen-free and RoHS requirements?
Yes, HER605GH complies with RoHS Directive 2011/65/EU and is halogen-free per IEC 61249-2-21. The epoxy molding compound contains no brominated flame retardants or chlorine-based additives, and the pure tin-plated leads satisfy J-STD-002 solderability standards. Full material declarations and compliance certificates are available upon request for HER605GH.
What is the reverse recovery time (trr) specification for HER605GH?
The HER605GH has a maximum reverse recovery time (trr) of 50 ns, measured at IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A. This fast recovery characteristic minimizes switching losses and ringing in high-frequency SMPS designs. The 50 ns trr is confirmed across temperature and is significantly shorter than general-purpose rectifiers (e.g., 1N5408: >200 ns), making HER605GH suitable for 100–500 kHz converters.
Can HER605GH be used in freewheeling applications?
Yes, HER605GH is explicitly recommended for freewheeling applications per Taiwan Semiconductor's official documentation. Its 150 A IFSM rating, 50 ns trr, and low VF make it ideal for clamping inductive kickback in relay drivers, motor controllers, and buck converter output stages. The R-6 package provides mechanical robustness for repeated surge events, and the AEC-Q101 qualification ensures reliability in automotive freewheeling circuits subject to vibration and thermal cycling.
