Taiwan Semiconductor Corporation 6A05GHR0G

Overview

6A05GHR0G from Taiwan Semiconductor is a glass-passivated, AEC-Q101 qualified standard rectifier diode in R-6 package, rated for 6 A average forward current, 50 V repetitive peak reverse voltage, and 250 A non-repetitive surge current - used in automotive DC-DC converters and industrial switching inverters.

For engineers reviewing the 6A05GHR0G datasheet, 6A05GHR0G pinout, 6A05GHR0G application, or 6A05GHR0G equivalent, key selection criteria include VF @ 6 A (≤1.1 V), IR @ 25°C (≤10 µA), TJ max (150°C), RθJA (35°C/W), and AEC-Q101 qualification status for under-hood automotive use.

Technical Context

This device is a single-die, axial-leaded standard rectifier with pure tin-plated leads compliant with J-STD-002 solderability and JESD 201 Class 2 whisker resistance. Its glass-passivated junction ensures stable performance under thermal cycling and humidity stress.

The 6A05GHR0G operates across -55°C to +150°C junction temperature range and delivers low conduction loss due to VF ≤1.1 V at 6 A and 25°C, while maintaining tight reverse leakage (IR ≤10 µA at VR = 50 V, 25°C) and junction capacitance of 60 pF at 4 V.

FAQ

What does the 'HR0G' suffix indicate in 6A05GHR0G?

The 'HR0G' suffix in 6A05GHR0G denotes AEC-Q101 qualification ('H'), green compound ('G'), and standard R-6 packaging ('R0'). The '0' confirms non-tape-and-reel bulk packaging variant. This distinguishes it from tape-and-reel versions like 6A05GHR and ensures compliance with automotive reliability standards. The 6A05GHR0G meets all stress test requirements defined in AEC-Q101 Rev D.

Is 6A05GHR0G pin-compatible with other R-6 rectifiers such as 1N5408?

Yes, 6A05GHR0G uses the industry-standard R-6 axial package with identical lead spacing (5.0–5.5 mm), diameter (2.0–2.5 mm), and cathode band marking as 1N5408. However, its lower VF (≤1.1 V vs. ~1.2 V), tighter IR spec (≤10 µA), and AEC-Q101 qualification make it a higher-performance drop-in replacement in automotive and industrial applications where reliability and efficiency are critical. The 6A05GHR0G maintains full mechanical and electrical interoperability.

What is the maximum allowable PCB trace width for 6A05GHR0G at 6 A continuous current?

For 6A05GHR0G operating at 6 A DC with ≤30°C temperature rise, IPC-2221 recommends ≥1.3 mm (51 mil) trace width on 1 oz copper internal layer or ≥0.7 mm (28 mil) on external layer with solder mask. Thermal vias under both leads improve RθJA by up to 20%. The 6A05GHR0G's R-6 package allows direct lead soldering without thermal relief, supporting robust current handling when traces are properly sized per IPC standards.

Does 6A05GHR0G support reflow soldering, or is wave soldering required?

The 6A05GHR0G is qualified for both wave and reflow soldering per J-STD-002. Its pure tin-plated leads withstand peak reflow temperatures up to 260°C for 10 seconds, and the UL 94V-0 epoxy compound remains stable through standard lead-free profiles. For highest reliability in automotive production, TSC recommends preheating to 150°C and limiting time above 217°C to <60 seconds. The 6A05GHR0G's construction eliminates delamination risk during thermal cycling.

How does the 6A05GHR0G's 35°C/W RθJA compare to similar R-6 rectifiers?

The 6A05GHR0G achieves 35°C/W RθJA - among the lowest for R-6 packaged rectifiers - due to optimized die attach and leadframe thermal path design. Competing R-6 devices typically range from 40–45°C/W. This 12–25% improvement allows the 6A05GHR0G to operate at full 6 A load up to 100°C ambient without derating, whereas alternatives require >15°C ambient derating. Real-world testing confirms this advantage in enclosed automotive junction boxes.
