Product details
Overview
6A60GH from Taiwan Semiconductor is a 6 A, 600 V AEC-Q101-qualified standard rectifier diode in R-6 package, featuring 1.0 V forward voltage at 6 A and 250 A surge capability, used in automotive-grade DC-DC converters and switching inverters.
For engineers reviewing the 6A60GH datasheet, 6A60GH pinout, 6A60GH application, or 6A60GH equivalent, key selection criteria include its AEC-Q101 qualification, 600 V repetitive peak reverse voltage, 1.0 V forward voltage at rated current, R-6 package thermal resistance of 35 °C/W, and cathode-band polarity marking.
Technical Context
This single-die standard rectifier operates with glass-passivated junction for enhanced reliability and low power loss. Its 600 V VRRM and 250 A IFSM support high-surge industrial and automotive power conversion stages.
The device delivers 1.0 V forward voltage at 6 A and 25 °C, with reverse leakage limited to 10 µA at 25 °C and 100 µA at 125 °C, enabling stable operation across automotive temperature ranges (−55 to +150 °C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - supports input rectification in 400 V AC line-derived or 300–450 V DC bus systems |
| IF | 6 A continuous - suitable for medium-power SMPS output stages and auxiliary supplies |
| IFSM | 250 A (8.3 ms half-sine) - withstands inrush and transient surges in motor drives and EV chargers |
| VF | 1.0 V @ 6 A, 25 °C - reduces conduction loss vs. higher-VF alternatives, improving efficiency |
| RθJA | 35 °C/W - enables natural-convection cooling in R-6 package without heatsink up to ~3.5 W dissipation |
| Junction Temp | −55 to +150 °C - meets extended automotive ambient and under-hood thermal requirements |
| Cathode Marking | Visible band - unambiguous polarity identification for automated assembly and field service |
Pinout & Package
Package: R-6 axial leaded, UL 94V-0 molded compound, pure tin-plated leads, 1.65 g weight, cathode indicated by band.
| Pin/Terminal | Circuit Role | Design Meaning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar standard rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH6L06S | 6 A, 600 V, TO-220AC package, VF = 1.15 V @ 6 A, RθJA = 45 °C/W | Higher thermal resistance requires heatsink; not AEC-Q101 qualified | Preferred for cost-sensitive industrial SMPS where qualification isn't required |
| ON Semi MUR660 | 6 A, 600 V, DO-201AD package, VF = 1.1 V @ 6 A, IFSM = 175 A | Lower surge rating; smaller package limits power handling; no AEC-Q101 | Used in space-constrained consumer adapters where automotive reliability is unnecessary |
Compared with STTH6L06S and MUR660, the 6A60GH provides superior surge robustness (250 A), lower forward drop (1.0 V), and automotive qualification-making it the only choice for AEC-compliant 6 A rectification where thermal margin and reliability are critical.

FAQ
What is the maximum junction temperature rating for the 6A60GH?
The 6A60GH has a maximum junction temperature (TJ) of +150 °C and a minimum of −55 °C, supporting operation in under-hood automotive environments and high-ambient industrial enclosures. This rating is validated per AEC-Q101 thermal cycling and high-temperature operating life tests. The 6A60GH maintains specified electrical performance across this full range when derated per its forward current derating curve.
Is the 6A60GH pin-compatible with other R-6 rectifiers like 6A40G or 6A80G?
Yes-the 6A60GH shares identical R-6 mechanical dimensions, lead spacing, and axial pinout with all members of the 6A05G–6A100G family, including 6A40G and 6A80G. The only differences are VRRM (600 V), marking code ("6A60G"), and AEC-Q101 qualification ("H" suffix). No PCB redesign is needed when substituting within this family for voltage-matched applications.
Does the 6A60GH require a heatsink in typical 6 A operation?
Not necessarily-the 6A60GH's RθJA of 35 °C/W allows up to ~3.5 W power dissipation (at ΔT = 122.5 °C above 25 °C ambient) with natural convection. At 6 A and 1.0 V VF, conduction loss is 6 W, so heatsinking is recommended above ~40 °C ambient or with sustained full-load duty. Derating per the datasheet curve ensures safe operation without forced cooling in many automotive auxiliary supplies.
What does the "H" suffix in 6A60GH signify?
Per Taiwan Semiconductor's ordering information, the "H" suffix in 6A60GH explicitly denotes AEC-Q101 qualification. This means the 6A60GH has undergone and passed the full suite of stress tests-including high-temperature reverse bias, temperature cycling, and unbiased highly accelerated stress testing-required for discrete semiconductors in automotive power systems. The base part 6A60G lacks this qualification.
How is polarity identified on the 6A60GH package?
Polarity on the 6A60GH is indicated by a visible cathode band near one lead end, consistent with R-6 industry convention. The banded lead is the cathode (output terminal during forward conduction); the opposite lead is the anode. This marking is laser-etched or molded into the epoxy body and remains legible after soldering, supporting both automated optical inspection and manual verification during rework.
