Taiwan Semiconductor Corporation 6A100GH

Overview

6A100GH from Taiwan Semiconductor is a glass-passivated, AEC-Q101 qualified standard rectifier diode rated for 6 A average forward current, 1000 V repetitive peak reverse voltage (V_RRM), and 250 A non-repetitive surge current (I_FSM). It operates with low forward voltage (1.0 V at 6 A, 25°C) and is used in high-reliability DC-DC converters and automotive-grade switching inverters.

For engineers reviewing the 6A100GH datasheet, 6A100GH pinout, 6A100GH application, or 6A100GH equivalent, key selection factors include its R-6 package thermal resistance (35 °C/W), junction capacitance (60 pF), AEC-Q101 qualification status, and cathode-band polarity marking - all critical for thermal design, EMI filtering, and automotive compliance validation.

Technical Context

This single-die standard rectifier uses a glass-passivated PN junction to achieve stable reverse blocking up to 1000 V and low conduction loss. Its 1.0 V forward voltage at 6 A and 25°C enables efficient power conversion in medium-power switching topologies.

The device features pure tin-plated leads compliant with J-STD-002 solderability, meets JESD201 Class 2 whisker resistance, and is molded in UL 94V-0 compound. Polarity is unambiguously indicated by a cathode band on the R-6 case.

FAQ

What is the maximum junction temperature rating for the 6A100GH?

The 6A100GH has a maximum junction temperature (T_J) of +150°C, validated across its full operating range from –55°C to +150°C. This rating supports use in under-hood automotive environments and sealed industrial enclosures. Thermal design must respect the 35 °C/W junction-to-ambient resistance to avoid exceeding this limit under sustained 6 A load conditions.

Is the 6A100GH pin-compatible with other R-6 rectifiers like 6A05G or 6A40G?

Yes - the 6A100GH shares identical R-6 package dimensions, lead spacing, and cathode-band polarity marking with all members of the 6A05G–6A100G series. Mechanical interchangeability is guaranteed; however, electrical differences (e.g., V_RRM, V_F) require circuit-level verification before substitution.

Does the 6A100GH require a heatsink in typical 6 A operation?

No heatsink is required for the 6A100GH at 6 A continuous current if ambient temperature remains ≤55°C and PCB copper area provides ≥2 cm² of 2 oz copper pour per lead. Its R-6 package and 35 °C/W R_θJA enable self-cooled operation in many medium-power applications - unlike TO-220 alternatives that mandate external heatsinking.

What does the "H" suffix signify in the 6A100GH part number?

Per Taiwan Semiconductor's ordering guide, the "H" suffix in 6A100GH explicitly denotes AEC-Q101 qualification. This includes stress testing for temperature cycling, mechanical shock, vibration, and high-temperature reverse bias - confirming suitability for automotive power electronics where reliability under thermal and mechanical stress is mandatory.

How is polarity identified on the 6A100GH package?

Polarity is marked by a distinct cathode band printed on the body of the 6A100GH's R-6 case. The lead adjacent to the band is the cathode; the opposite lead is the anode. This marking complies with JEDEC standards and is machine-readable for automated optical inspection (AOI) in SMT reflow or through-hole assembly lines.
