Product details

Overview

1T6GH from Taiwan Semiconductor is a 1 A, 800 V repetitive peak reverse voltage standard rectifier diode in TS-1 package, featuring low forward voltage (1.0 V at 1 A, 25°C), 30 A surge capability, and AEC-Q101 qualification for automotive-grade reliability.

For engineers reviewing the 1T6GH datasheet, 1T6GH pinout, 1T6GH application, or 1T6GH equivalent, key selection factors include its 800 V V_RRM, TS-1 miniature body with pure tin-plated leads, junction-to-ambient thermal resistance of 100 °C/W, and compliance with JESD 201 Class 2 whisker testing.

Technical Context

This single-die standard rectifier operates across -55°C to +150°C junction temperature range and supports DC–DC converters and switching-mode inverters requiring stable unidirectional conduction under repetitive reverse voltage stress up to 800 V and transient surges up to 30 A (8.3 ms half-sine).

Its 10 pF junction capacitance at 1 MHz / 4.0 V reverse bias and ≤5 µA reverse leakage at 25°C support high-frequency switching efficiency while maintaining low standby power loss in flyback and boost topologies.

Key Specifications

I_FSM	30 A - Non-repetitive surge current capacity; enables robustness against line transients and inrush events
V_F	1.0 V @ 1 A, 25°C - Forward voltage drop directly impacts conduction loss and thermal rise in high-duty-cycle operation
R_θJA	100 °C/W - Junction-to-ambient thermal resistance; determines required heatsinking or board layout for 150°C max junction temp
C_J	10 pF @ 1 MHz, 4.0 V - Junction capacitance affects switching speed and EMI generation in high-frequency SMPS designs

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STTH1R08	Same 1 A / 800 V rating; TO-220AC package (larger footprint, higher R_θJA = 50 °C/W)	Requires heatsink above ~0.5 A continuous; not AEC-Q101 qualified	Prefer when higher thermal mass needed and automotive qualification unnecessary
ON Semi MUR108	Ultrafast recovery (t_rr = 75 ns); same TS-1 package and 1 A / 800 V rating	Better suited for >100 kHz switching; higher V_F (1.3 V) increases conduction loss	Choose when reduced switching loss outweighs conduction loss penalty in high-frequency designs

Compared with STTH1R08 and MUR108, the 1T6GH delivers automotive-grade reliability in a miniature TS-1 package with optimized conduction efficiency-making it ideal for space- and qualification-constrained 800 V rectification where ultrafast recovery is not required.

FAQ

What is the maximum repetitive peak reverse voltage (V_RRM) of the 1T6GH?

The 1T6GH has a maximum repetitive peak reverse voltage (V_RRM) of 800 V, as confirmed in the Absolute Maximum Ratings table of the official Taiwan Semiconductor datasheet (Version H2104). This rating defines the highest reverse voltage the device can block repeatedly without breakdown and is critical for selecting appropriate input voltage margins in AC/DC and DC/DC converter designs using the 1T6GH.

Is the 1T6GH AEC-Q101 qualified?

Yes, the 1T6GH is AEC-Q101 qualified, as explicitly stated in the FEATURES section and ordering code notation ("H" suffix denotes AEC-Q101 qualification). This qualification covers stress tests including temperature cycling, high-temperature operating life, and unbiased highly accelerated stress testing-ensuring suitability for automotive underhood applications where the 1T6GH is deployed in power supplies for ECUs and ADAS systems.

What package type does the 1T6GH use, and what are its mechanical highlights?

The 1T6GH uses the TS-1 package: a 3 mm miniature molded body with pure tin-plated leads compliant with J-STD-002 solderability and JESD 201 Class 2 whisker resistance. Its polarity is indicated by a cathode band, and the molding compound meets UL 94V-0 flammability rating-making the 1T6GH suitable for compact, high-reliability PCB layouts in automotive and industrial environments.

What is the forward voltage (V_F) of the 1T6GH at rated current?

The forward voltage (V_F) of the 1T6GH is 1.0 V maximum at I_F = 1 A and T_J = 25°C, per the Electrical Specifications table. This value is measured under pulse conditions (PW = 0.3 ms), and actual V_F rises with junction temperature-reaching approximately 1.05 V at 125°C. This low V_F directly reduces conduction loss in the 1T6GH compared to higher-drop alternatives in the same voltage class.

Does the 1T6GH have a specified junction-to-ambient thermal resistance (R_θJA)?

Yes, the 1T6GH has a junction-to-ambient thermal resistance (R_θJA) of 100 °C/W, as published in the Thermal Performance section of the datasheet. This value assumes standard JEDEC test conditions (single device on 1-inch² FR-4 board with 2 oz copper) and is used to calculate expected junction temperature rise under given power dissipation-essential for thermal design validation of circuits using the 1T6GH.
