Taiwan Semiconductor Corporation 6A60G

Overview

6A60G from Taiwan Semiconductor is a glass-passivated standard rectifier diode rated for 6 A average forward current, 600 V repetitive peak reverse voltage, and 250 A surge current, with 1.0 V typical forward voltage at 6 A and 25°C - used in switching-mode power supplies and DC-DC converters.

For engineers reviewing the 6A60G datasheet, 6A60G pinout, 6A60G application, or 6A60G equivalent, key selection criteria include V_RRM = 600 V, I_F = 6 A, I_FSM = 250 A, T_J max = 150°C, and R-6 package compatibility with high-reliability industrial and automotive-grade power conversion designs.

Technical Context

The 6A60G operates as a single-die, unidirectional silicon rectifier with glass-passivated junction for enhanced moisture and contamination resistance. Its thermal resistance R_θJA is 35°C/W, enabling stable operation up to 150°C junction temperature under natural convection.

It delivers low conduction loss (V_F = 1.0 V typ. @ 6 A, 25°C) and low leakage (I_R ≤ 10 µA @ 25°C, rated V_R), with junction capacitance of 60 pF at 1 MHz and 4 V reverse bias - suitable for medium-frequency switching applications up to ~100 kHz.

The following parts are listed as comparable options for similar standard rectifier applications.

Compared with STTH6L06D and MUR660CT, the 6A60G offers superior surge capability (250 A vs. 170 A/125 A), lower forward drop (1.0 V vs. 1.15 V/1.7 V), and axial R-6 packaging ideal for through-hole power supply layouts - making it optimal for cost-sensitive, medium-frequency industrial rectification where reliability and ease of assembly are prioritized.

Availability

6A60G is available at Aetrix Electronics and suitable for AC/DC adapters, industrial DC-DC converters, and solar microinverter auxiliary supplies requiring stable component supply, long-term manufacturability, and RoHS-compliant sourcing.

Supply support for 6A60G 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

Taiwan Semiconductor Corporation (TSC) is a vertically integrated analog and discrete semiconductor manufacturer headquartered in Hsinchu, Taiwan, serving industrial, computing, and consumer markets since 1979.

The 6A60G belongs to TSC's R-6 axial rectifier family, engineered for high-reliability, cost-optimized AC/DC and DC/DC power conversion where robust surge handling, low forward loss, and environmental resilience are essential.

FAQ

What is the maximum junction temperature rating for the 6A60G?

The 6A60G has a maximum junction temperature (T_J) rating of +150°C, verified per absolute maximum ratings in the official TSC datasheet (Version F2104). This allows reliable operation in high-ambient industrial enclosures. Derating is required above 75°C case temperature to maintain safe thermal margins. The 6A60G achieves this rating using a glass-passivated silicon die in an R-6 package with 35°C/W junction-to-ambient thermal resistance.

Does the 6A60G have automotive qualification?

The base 6A60G is not AEC-Q101 qualified, but its variant 6A60GH is explicitly listed as AEC-Q101 qualified in TSC's ordering information. The 6A60GH shares identical electrical and thermal specifications with the 6A60G, differing only in additional automotive-grade process controls and test screening. For automotive under-hood applications, specify 6A60GH - the 6A60G itself is intended for industrial and commercial use.

What is the forward voltage of the 6A60G at 6 A and 125°C?

The datasheet specifies V_F = 1.0 V typical at 6 A and 25°C; however, no V_F value is provided at 125°C. Based on silicon diode physics and TSC's typical forward characteristics curve (Fig.4), V_F decreases by ~2 mV/°C - resulting in approximately 0.82 V at 125°C. This lower V_F reduces conduction loss at elevated temperatures, but system design must still verify thermal stability using the 6A60G's 150°C T_J limit.

Can the 6A60G replace the 6A40G in a 400 V design?

Yes - the 6A60G is backward-compatible with 400 V designs originally using the 6A40G, as its 600 V V_RRM exceeds the 400 V requirement and all other parameters (I_F, I_FSM, V_F, package) are identical. No layout or thermal changes are needed. However, the 6A60G should not be substituted for lower-voltage variants (e.g., 6A05G) unless reverse voltage margin is confirmed sufficient for the application's worst-case transients.

What does the 'G' suffix indicate in the 6A60G part number?

The 'G' suffix in 6A60G denotes green molding compound compliant with RoHS and halogen-free standards per IEC 61249-2-21. It is not a grade or revision indicator. All parts in the 6A05G–6A100G series share this 'G' suffix, confirming environmental compliance. The voltage rating is encoded in the numeric portion: '60' = 600 V (V_RRM). The 6A60G uses the R-6 package with pure tin-plated leads solderable per J-STD-002.
