Product details
Overview
6A40G from Taiwan Semiconductor is a 6 A, 400 V glass-passivated standard rectifier diode in R-6 package, featuring 1.0 V forward voltage at 6 A and 250 A surge capability, used in switching mode power supplies and DC-DC converters.
For engineers reviewing the 6A40G datasheet, 6A40G pinout, 6A40G application, or 6A40G equivalent, key selection criteria include repetitive peak reverse voltage (400 V), forward current rating (6 A), thermal resistance (35 °C/W), junction capacitance (60 pF), and RoHS/halogen-free compliance for automotive and industrial power conversion designs.
Technical Context
This single-die standard rectifier operates with a maximum junction temperature of 150 °C and supports continuous forward current up to 6 A at ambient conditions, with 250 A non-repetitive surge tolerance per 8.3 ms half-sine wave.
Its R-6 package uses pure tin-plated leads compliant with J-STD-002 solderability and JESD 201 Class 2 whisker resistance, and features cathode band polarity marking with UL 94V-0 molding compound.

Equivalent & Alternatives
The following parts are listed as comparable options for similar standard rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH6R04G | 6 A, 400 V, TO-220AC package; VF = 1.15 V @ 6 A; RθJA = 50 °C/W | Higher thermal resistance requires heatsink; unsuitable for compact R-6 footprint replacement | Select when board-level heatsinking is available and lead-forming flexibility is needed |
| ON Semi MUR640CT | 6 A, 400 V, TO-220AB dual common-cathode; VF = 0.92 V @ 6 A; faster recovery but higher cost | Designed for dual-output or center-tap configurations; not a single-diode drop-in | Choose for improved efficiency in low-VF-sensitive designs where dual-diode layout is acceptable |
Compared with STTH6R04G and MUR640CT, the 6A40G offers lowest profile and simplest mounting via R-6 axial leads, best suited for cost-sensitive, space-constrained, and high-volume through-hole power supplies where thermal budget permits natural convection cooling.

FAQ
What is the maximum junction temperature rating for the 6A40G?
The 6A40G has a maximum junction temperature (TJ) rating of +150 °C, allowing reliable operation in high-ambient environments such as enclosed power supplies or under-hood automotive applications. This rating is maintained across its full operating current range and supports derating curves defined in the datasheet. Thermal design must ensure that actual junction temperature stays within this limit during steady-state and transient conditions for the 6A40G.
Does the 6A40G have AEC-Q101 qualification?
The base 6A40G is not AEC-Q101 qualified; however, the variant 6A40GH is explicitly qualified to AEC-Q101 for automotive applications. The "H" suffix denotes qualification, including stress testing for temperature cycling, humidity, and mechanical shock. For automotive-grade deployment, engineers must specify 6A40GH-not 6A40G-to ensure compliance. The 6A40G remains suitable for industrial and consumer use where AEC-Q101 is not mandated.
What is the forward voltage drop of the 6A40G at rated current?
The 6A40G exhibits a typical forward voltage (VF) of 1.0 V at 6 A and 25 °C junction temperature, measured under pulsed conditions (PW = 0.3 ms). This value increases with temperature and current-reaching ~1.15 V at 125 °C-so system-level conduction loss calculations must account for thermal derating. The low VF directly contributes to reduced power dissipation in the 6A40G compared to higher-drop alternatives.
What packaging options are available for the 6A40G?
The 6A40G is offered in two standard packaging formats: 1,000-piece tape-and-reel (ordering code 6A40G) and 700-piece ammo box (ordering code 6A40G A0G). Both use the R-6 axial-leaded package with green molding compound and cathode band marking. The "A0G" suffix specifically denotes the ammo box packing method and does not affect electrical or thermal specifications of the 6A40G device itself.
How does the 6A40G compare to the 6A60G in terms of voltage rating and application suitability?
The 6A40G is rated for 400 V repetitive peak reverse voltage (VRRM), while the 6A60G is rated for 600 V. Both share identical current (6 A), surge (250 A), thermal (35 °C/W), and package (R-6) characteristics. The 6A40G is optimal for 230 VAC-derived supplies with margin; the 6A60G suits 400 VDC bus or 3-phase rectified inputs. Selecting 6A40G avoids over-specification where 400 V blocking suffices, reducing cost and size without compromising safety in the 6A40G's target applications.
