Product details
Overview
6A6-T from Diodes Incorporated is a 6.0A, 600V maximum recurrent peak reverse voltage axial-lead silicon rectifier diode in R-6 molded plastic package, featuring 0.90V max forward voltage at 6.0A DC and 400A peak surge capability, used in AC/DC power supplies and industrial rectification circuits.
For engineers reviewing the 6A6-T datasheet, 6A6-T pinout, 6A6-T application, or 6A6-T equivalent, key selection criteria include VRRM=600V, I(AV)=6.0A at +75°C with 9.5mm lead length, IFSM=400A (8.3ms half-sine), VFM=0.90V @6A, and IRM=10µA @25°C - all critical for high-reliability linear and transformer-based power conversion designs.
Technical Context
This device operates as a single-phase, half-wave silicon rectifier under 60Hz resistive or inductive loads. Its R-6 axial package supports through-hole mounting with tin-finished leads compliant to MIL-STD-202 Method 208, and UL 94V-0 flammability rating ensures safety in enclosed power assemblies.
Thermal performance is defined for TA = +75°C ambient with 9.5mm lead length; junction temperature range spans –65°C to +175°C, enabling deployment in industrial environments with wide ambient swings and transient thermal stress.
Key Specifications

| I(AV) | 6.0 A - Average forward current rating at +75°C ambient with 9.5 mm lead length, defining continuous power handling |
| IFSM | 400 A - Peak non-repetitive surge current tolerance (8.3 ms half-sine), critical for inrush and fault immunity |
| VFM | 0.90 V @ 6.0 A DC - Forward voltage drop determining conduction loss and thermal rise in rectifier stage |
| IRM | 10 µA @ 25°C - Reverse leakage current at rated blocking voltage, impacting standby power and isolation integrity |
| TJ Range | –65°C to +175°C - Operating junction temperature window supporting extended industrial and automotive under-hood use |

Equivalent & Alternatives
The following parts are listed as comparable options for similar silicon rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| GBU6K | Single-in-line (GBU) package; 600V VRRM, 6A I(AV), but higher VFM (1.1V @6A) | Surface-mount compatible; requires PCB footprint change and reflow process instead of axial through-hole | Select when board space is constrained and SMT assembly is preferred over through-hole |
| DF005M | Bridge rectifier (4-diode module); 50V VRRM, 0.8A I(AV) - lower voltage/current rating | Provides full-wave rectification in one package; not a direct replacement due to different topology and ratings | Use only in low-voltage, low-power full-wave applications where discrete single-diode replacement is unnecessary |
Compared with GBU6K and DF005M, the 6A6-T offers superior thermal derating margin at +75°C, lower conduction loss, and proven reliability in high-surge industrial environments - making it optimal for discrete, high-current, through-hole rectifier roles where cost, simplicity, and ruggedness are prioritized.

FAQ
What is the maximum allowable ambient temperature for continuous 6.0A operation?
The 6A6-T is rated for 6.0A average forward current at +75°C ambient temperature with 9.5mm lead length. Operation above this temperature requires derating per Figure 1 in DS28009; at +100°C ambient, I(AV) drops to approximately 4.5A based on thermal resistance and junction-to-ambient characteristics.
Is the 6A6-T suitable for full-wave bridge configurations?
Yes - the 6A6-T is a single-junction axial diode intended for use in discrete full-wave bridge rectifiers. Four units can be assembled into a standard bridge; its 600V VRRM and 400A IFSM make it appropriate for 240VAC input bridges where each diode sees up to ~340V peak reverse voltage.
Does the R-6 package support automated through-hole insertion?
Yes - the R-6 package features straight axial leads with consistent diameter and spacing, designed for compatibility with standard axial-component insertion equipment. Lead finish is tin, meeting MIL-STD-202 Method 208 for solderability, and the 2.1g weight falls within typical machine-handling tolerances.
Why is the 6A6-T marked "NOT RECOMMENDED FOR NEW DESIGN"?
This marking reflects Diodes Incorporated's internal product lifecycle guidance: while fully functional and supported, newer alternatives like the GBU6K or surface-mount equivalents offer improved thermal performance or assembly efficiency. The 6A6-T remains available and qualified for legacy refresh and cost-driven through-hole designs where R-6 compatibility is essential.
