Diodes Incorporated 2A06-T

Overview

2A06-T from Diodes Incorporated is a 2.0A, 800V peak repetitive reverse voltage (VRRM) general-purpose silicon rectifier diode in DO-15 package, featuring low forward voltage drop (1.1V @ 2.0A), 70A non-repetitive surge capability, and RoHS-compliant bright tin terminals. It serves as a primary AC-to-DC conversion element in offline power supplies, battery chargers, and industrial control power stages.

For engineers reviewing the 2A06-T datasheet, 2A06-T pinout, 2A06-T application, or 2A06-T equivalent, key selection criteria include VRRM derating for capacitive loads, thermal resistance (60°C/W), junction temperature limits (–65°C to +150°C), and DO-15 mechanical compatibility with through-hole PCB layouts.

Technical Context

This axial-lead rectifier operates in single-phase, half-wave configurations at 60Hz with resistive or inductive loads. Its diffused junction enables stable performance across –65°C to +150°C ambient and junction temperatures, and its 15pF typical junction capacitance supports moderate-frequency rectification without excessive switching loss.

The device requires lead-length thermal management (9.5mm from case) to sustain rated 2.0A average output current at 55°C ambient. Derating is mandatory for capacitive loads (20% current reduction) and higher ambient temperatures per Fig. 1 forward current derating curve.

FAQ

Is 2A06-T suitable for capacitive-load applications?

No-datasheet explicitly requires 20% derating of average forward current (IO) when used with capacitive loads. At 55°C ambient, rated IO drops from 2.0A to 1.6A. Layout must also include inrush limiting (e.g., NTC thermistor or active soft-start) to avoid exceeding 70A IFSM during cold start.

What is the maximum ambient temperature for full 2.0A operation?

Full 2.0A average current is only guaranteed at TA = 55°C with 9.5mm lead length. Above that, current must be linearly derated per Fig. 1: at 75°C ambient, max IO ≈ 1.5A; at 100°C, ≈ 0.8A. Thermal vias and copper pour are recommended to improve effective RθJA in PCB designs.

Does 2A06-T have a qualified automotive grade variant?

No-2A06-T is not AEC-Q101 qualified and is not recommended for automotive powertrain or safety-critical systems. Diodes Incorporated offers automotive-grade alternatives (e.g., DFLS280Q) with extended temperature screening, PPAP documentation, and zero-defect manufacturing, but those use different packages and qualification test plans.

Can 2A06-T replace 2A05-T in an existing design?

Yes-with caution. Both share identical package, thermal specs, and surge rating, but 2A05-T has 600V VRRM vs. 2A06-T's 800V. Substitution is safe if system peak reverse voltage remains ≤600V; however, using 2A06-T in place of 2A05-T adds reverse voltage margin without altering layout or thermal behavior.
