Diodes Incorporated 6A2-T

Overview

6A2-T from Diodes Incorporated is a 200 V, 6.0 A average forward current silicon rectifier diode in R-6 axial package, designed for AC/DC conversion in power supplies and input stage rectification. It delivers 0.90 V forward voltage at 6.0 A DC, supports 400 A non-repetitive surge current, and operates from –65°C to +175°C with RoHS-compliant tin-plated leads.

For engineers reviewing the 6A2-T datasheet, 6A2-T pinout, 6A2-T application, or 6A2-T equivalent, key selection criteria include peak reverse voltage (200 V), thermal derating behavior above +75°C, axial lead mechanical mounting constraints, and compatibility with 60 Hz half-wave resistive/inductive loads.

Technical Context

This device is a single-junction, planar passivated silicon PN junction rectifier optimized for general-purpose industrial and consumer power conversion. Its R-6 molded plastic case provides UL 94V-0 flammability rating and moisture sensitivity level 1 handling.

It conducts current unidirectionally with cathode indicated by color band, requires no gate drive or biasing, and exhibits low leakage (10 µA @ 25°C, 100 µA @ 100°C) under rated blocking voltage.

FAQ

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

The 6A2-T is rated for 6.0 A average forward current only at TA = +75°C with 9.5 mm lead length. At higher ambient temperatures, derating is required per Figure 1 in DS28009. At +100°C ambient, maximum I(AV) drops to approximately 4.2 A due to thermal resistance limitations of the R-6 package.

Can 6A2-T replace 6A4-T in a 400 V design?

No. The 6A2-T has VRRM = 200 V and must not be substituted for the 6A4-T (VRRM = 400 V) in circuits where reverse voltage exceeds 200 V. Doing so risks catastrophic avalanche failure. Designers must verify peak reverse voltage in the actual application, including line transients and ringing.

Is 6A2-T suitable for full-wave bridge configurations?

Yes - the 6A2-T is a single diode and can be used as one quadrant in a discrete full-wave bridge. Four units are required per bridge. Its 400 A IFSM and 200 V VRRM make it appropriate for 120 VAC full-wave applications, but designers must ensure balanced thermal distribution and adequate PCB copper area for each device.

Does 6A2-T have a qualified AEC-Q101 rating for automotive use?

No. The 6A2-T is not AEC-Q101 qualified. While its –65°C to +175°C operating range overlaps with some automotive under-hood requirements, Diodes Incorporated does not list this part in its AEC-Q101 qualified portfolio. Automotive designs requiring qualification must select from the manufacturer's designated AEC-Q101 rectifier series.
