Diodes Incorporated 6A10-T

Overview

6A10-T from Diodes Incorporated is a 6.0A, 1000V peak repetitive reverse voltage axial-lead silicon rectifier diode in R-6 molded plastic package, with 0.90V max forward voltage at 6.0A DC and 400A surge capability, used in AC/DC power supplies and industrial rectification circuits.

For engineers reviewing the 6A10-T datasheet, 6A10-T pinout, 6A10-T application, or 6A10-T equivalent, key selection criteria include VRRM=1000V, I(AV)=6.0A at +75°C, VFM=0.90V @6A, IFSM=400A (8.3ms), and IRM=10µA @25°C - all critical for high-voltage offline rectifier design and thermal reliability validation.

Technical Context

This device operates as a single-phase, half-wave silicon rectifier optimized for 60Hz line-frequency applications with resistive or inductive loads. Its R-6 axial package supports lead-forming for through-hole PCB mounting and meets UL 94V-0 flammability rating.

Rated for continuous operation from –65°C to +175°C junction temperature, it delivers stable reverse blocking up to 1000V (VRRM) and low conduction loss (VFM ≤0.90V), enabling efficient energy conversion in high-input-voltage power stages.

FAQ

What is the maximum allowable ambient temperature for continuous 6.0A operation?

The 6A10-T is rated for I(AV) = 6.0A at TA = +75°C with 9.5mm lead length. At higher ambient temperatures, derating is required per Figure 1 in DS28009. At +100°C ambient, maximum average current drops to approximately 4.2A due to thermal resistance limitations of the R-6 package.

Is the 6A10-T suitable for use in a full-wave bridge configuration?

Yes - the 6A10-T is a single diode intended for use in discrete full-wave bridge assemblies. Four units can be configured as a standard bridge rectifier. Its 1000V VRRM and 400A IFSM make it appropriate for 400VDC output bridges fed from 230VAC or 347VAC sources.

Does the R-6 package support automated insertion or only manual assembly?

The R-6 package features straight axial leads compatible with standard wave soldering and selective soldering processes. While not designed for high-speed axial auto-insertion like radial packages, it is widely used in semi-automated and manual assembly lines, especially where lead forming or clinching is applied prior to soldering.

How does the 6A10-T compare to Schottky alternatives in high-voltage applications?

Schottky diodes are unsuitable above ~200V due to excessive reverse leakage. The 6A10-T's silicon PN junction enables reliable 1000V blocking with only 10µA IRM at 25°C - a key advantage for high-VRMS applications where Schottky devices would fail catastrophically under reverse bias.
