Taiwan Semiconductor Corporation 1T6G

Overview

1T6G from Taiwan Semiconductor is a single-die standard rectifier diode rated for 800 V repetitive peak reverse voltage (V_RRM), 1 A average forward current (I_F), and 30 A non-repetitive surge current (I_FSM), housed in a TS-1 package with 3 mm miniature body. It delivers low forward voltage drop (1.0 V max at 1 A, 25°C) and supports DC-DC converters and switching-mode inverters requiring reliable 800 V blocking capability.

For engineers reviewing the 1T6G datasheet, 1T6G pinout, 1T6G application, or 1T6G equivalent, key selection criteria include its 800 V V_RRM, 1.0 V V_F max, TS-1 package thermal resistance (R_θJA = 100 °C/W), AEC-Q101 qualification option, and cathode-band polarity marking - all critical for automotive and industrial power supply designs.

Technical Context

The 1T6G operates as a unidirectional silicon PN junction rectifier optimized for medium-voltage, medium-current switching power applications. Its 800 V V_RRM rating enables use in 400–600 V DC bus systems, while its 30 A I_FSM withstands transient surges common in SMPS startup and load dump events.

Thermally, the TS-1 package provides R_θJA = 100 °C/W and supports operation from –55°C to +150°C junction temperature. The device exhibits 10 pF junction capacitance at 1 MHz/4 V and maintains ≤5 µA reverse leakage at 25°C, ensuring low dynamic losses and stable blocking performance.

FAQ

What is the maximum repetitive peak reverse voltage (V_RRM) of the 1T6G?

The 1T6G has a V_RRM of 800 V, as confirmed in the Absolute Maximum Ratings table across all versions (H2104). This value is fixed for the 1T6G variant and distinguishes it from adjacent family members (e.g., 1T5G = 600 V, 1T7G = 1000 V). Designers must ensure this rating exceeds the peak reverse voltage seen in circuit operation by ≥20% for long-term reliability. The 1T6G's 800 V rating makes it suitable for 400 V nominal DC bus systems.

Is the 1T6G AEC-Q101 qualified?

The base 1T6G is not automatically AEC-Q101 qualified; qualification applies only to variants marked with "H" suffix (e.g., 1T6GH). Per Ordering Information, "H" denotes AEC-Q101 compliance, and the datasheet states "AEC-Q101 qualified available" for the 1T1G–1T7G family. Therefore, 1T6G itself requires explicit ordering as 1T6GH to meet automotive stress test requirements. Always verify the full part number on reel labels and certificates.

What is the forward voltage (V_F) specification for the 1T6G at rated current?

The 1T6G has a maximum forward voltage of 1.0 V at I_F = 1 A and T_J = 25°C, as specified in the Electrical Specifications table under "1T3G – 1T7G" grouping. This is lower than the 1.1 V limit for 1T1G/1T2G, reflecting process optimization for higher-voltage variants. At elevated temperatures (e.g., 125°C), V_F decreases slightly, improving conduction efficiency in thermally stressed conditions.

Which package does the 1T6G use, and what are its key mechanical attributes?

The 1T6G uses the TS-1 package: a 3 mm miniature molded body with pure tin-plated leads compliant with J-STD-002 solderability and JESD201 Class 2 whisker testing. Its UL 94V-0 flammability rating and 0.200 g weight support high-density, safety-certified PCB layouts. Polarity is marked by a cathode band, and the package is optimized for tape-and-reel automation (5,000 pcs/reel) or ammo box (3,000 pcs) handling.

How does the 1T6G compare to the 1T5G and 1T7G in terms of key electrical parameters?

The 1T6G sits between 1T5G (600 V V_RRM) and 1T7G (1000 V V_RRM) in the family, sharing identical I_F = 1 A, I_FSM = 30 A, and T_J = –55 to +150°C ratings. Its V_F = ≤1.0 V matches 1T3G–1T7G, while 1T1G/1T2G specify ≤1.1 V. Reverse leakage (I_R ≤5 µA at 25°C) and junction capacitance (C_J = 10 pF) are consistent across all variants, confirming process uniformity within the 1T1G–1T7G series.
