Diodes Incorporated 6A05-T

Overview

6A05-T from Diodes Incorporated is a 6.0A axial-lead silicon rectifier diode in R-6 package, rated for 50V maximum recurrent peak reverse voltage (VRRM), 0.90V forward voltage drop at 6.0A DC, and 400A surge current capability-designed for AC/DC power conversion in industrial power supplies and lighting ballasts.

For engineers reviewing the 6A05-T datasheet, 6A05-T pinout, 6A05-T application, or 6A05-T equivalent, key selection criteria include VRRM margin for line-voltage transients, thermal derating above +75°C ambient, RMS voltage compatibility with 60Hz transformer secondaries, and lead-free RoHS 3 compliance for modern manufacturing.

Technical Context

This device operates as a single-phase, half-wave rectifier under resistive or inductive loads at 60Hz. Its 50V VRRM rating targets low-voltage AC input stages, while the 9.5mm lead length specification defines thermal resistance to PCB copper area for I(AV) = 6.0A at TA = +75°C.

The 0.90V VFM at 6.0A reflects optimized P-N junction design for conduction loss minimization, and the 10µA IRM at 25°C ensures low standby leakage in offline power circuits where reverse-bias stability is critical.

Key Features

Applications

Availability

6A05-T is available at Aetrix Electronics and suitable for industrial power supplies, LED driver front-ends, and AC fan controllers requiring stable component supply with RoHS 3 compliance and high-surge resilience.

Supply support for 6A05-T includes scheduled delivery planning, volume procurement assistance, BOM continuity management, traceable sourcing, and lifecycle availability coordination for OEM customers, industrial embedded developers, connected-device designers, and electronics production programs.

Manufacturer

Diodes Incorporated is a global manufacturer of discrete semiconductors and analog ICs, headquartered in Plano, Texas, with design and manufacturing operations across Asia and the Americas.

The 6A05-T belongs to the 6Axx general-purpose rectifier family, engineered for cost-sensitive, high-volume AC/DC conversion where reliability under surge and thermal stress is prioritized over ultra-low VFM.

FAQ

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

The 6A05-T is rated for 6.0A average forward current only at TA = +75°C with 9.5mm lead length. At higher ambient temperatures, derating is required per Figure 1 in DS28009 Rev. 11-e.g., ~4.5A at +100°C ambient. PCB copper area and airflow directly affect achievable current.

Can the 6A05-T replace a 1N4005 in existing designs?

Yes, the 6A05-T is a direct upgrade: both are DO-41/R-6 axial devices with 50V VRRM, but the 6A05-T delivers 6.0A I(AV) vs. 1N4005's 1.0A and 400A IFSM vs. 30A. Thermal design must be re-evaluated due to higher power dissipation at full load.

Is the 6A05-T suitable for use in automotive under-hood applications?

No-while its TJ range extends to +175°C, the 6A05-T is not AEC-Q101 qualified and lacks automotive-specific screening, traceability, or failure-rate data. It is intended for industrial, commercial, and consumer power supplies-not safety-critical automotive environments.

Does the "-T" suffix indicate tape-and-reel packaging only?

Yes-the "-T" suffix denotes 500-piece tape-and-reel packaging on 13-inch reels, per Diodes Incorporated's ordering information. The base part "6A05" refers to the die and package; "-T" specifies this standard logistics format for SMT-compatible manual or semi-automated placement.
