Product details
Overview
6A05G from Taiwan Semiconductor is a 6 A, 50 V glass-passivated standard rectifier diode in R-6 package, featuring 1.1 V forward voltage at 6 A and 250 A surge capability, used in DC-DC converters and switching-mode power supplies.
For engineers reviewing the 6A05G datasheet, 6A05G pinout, 6A05G application, or 6A05G equivalent, key selection criteria include repetitive peak reverse voltage (50 V), forward current rating (6 A), thermal resistance (35 °C/W), junction temperature range (–55 to +150 °C), and AEC-Q101 qualification availability.
Technical Context
This single-die standard rectifier operates with a maximum junction temperature of 150 °C and exhibits low forward voltage (1.1 V @ 6 A, 25 °C) due to optimized silicon junction design and glass passivation. Its R-6 package supports high-reliability soldering per J-STD-002 and meets JESD 201 Class 2 whisker resistance.
The device delivers 250 A non-repetitive surge current (8.3 ms half-sine) and maintains reverse leakage ≤10 µA at 25 °C and ≤100 µA at 125 °C, enabling stable operation in high-transient industrial and automotive auxiliary power stages.

Equivalent & Alternatives
The following parts are listed as comparable options for similar standard rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor MUR620CT | 6 A, 200 V, TO-220AB package, VF = 1.15 V @ 6 A, faster recovery (~75 ns) | Higher VRRM and faster recovery suit higher-voltage SMPS; TO-220 requires mounting hardware | Select when >50 V blocking or faster switching is required; not drop-in for R-6 footprint |
| Vishay VS-6A50S-E3 | 6 A, 50 V, DO-201AD package, VF = 1.1 V @ 6 A, RθJA = 50 °C/W | Same voltage/current rating but higher thermal resistance limits power density | Acceptable where board space permits larger DO-201AD and lower power dissipation is acceptable |
Compared with MUR620CT and VS-6A50S-E3, the 6A05G offers optimal balance of low VF, R-6 axial form factor, and 35 °C/W thermal performance for cost-sensitive, medium-power rectification where 50 V blocking suffices.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) for the 6A05G?
The 6A05G has a VRRM of 50 V, meaning it can reliably block up to 50 V of reverse voltage in repetitive operation without breakdown. This rating is confirmed in the Absolute Maximum Ratings table of the F2104 datasheet and defines its use in low-voltage rectification circuits such as 12 V or 24 V input power stages. Exceeding this voltage risks irreversible junction failure.
Is the 6A05G suitable for automotive applications?
Yes - an AEC-Q101 qualified version of the 6A05G is available (marked as 6A05GH). While the base 6A05G is not AEC-Q101 certified, its construction (glass-passivated junction, JESD 201 Class 2 whisker resistance, and –55 to +150 °C TJ range) supports automotive-adjacent uses. For production automotive ECUs, specify the "H" suffix variant to ensure qualification.
What is the forward voltage (VF) of the 6A05G at rated current?
The 6A05G exhibits a typical forward voltage of 1.1 V at 6 A and 25 °C, measured under pulsed conditions (PW = 0.3 ms). This value increases with junction temperature - at 125 °C, VF drops slightly (~1.05 V) due to negative temperature coefficient of silicon. The low VF directly reduces conduction loss and improves thermal margin in high-current rectifier designs.
Does the 6A05G have a defined thermal resistance value?
Yes - the 6A05G has a specified junction-to-ambient thermal resistance (RθJA) of 35 °C/W under standard test conditions (free-air, no heatsink). This value assumes the device is mounted on a PCB with minimal copper area. With 1 in² of 2 oz copper pour, RθJA may improve to ~25 °C/W. It enables ~3.5 W of continuous power dissipation at 50 °C ambient before reaching 150 °C junction limit.
How is polarity indicated on the 6A05G package?
Polarity is indicated by a cathode band printed on the body of the 6A05G - the banded end corresponds to the cathode terminal (lead 2). This marking aligns with industry-standard R-6 axial package conventions and must be observed during PCB layout and assembly to prevent reverse-bias damage. The anode is the unmarked lead (lead 1), and correct orientation ensures proper rectification function.
