Product details

Overview

1N5402GHA0G from Taiwan Semiconductor is a glass-passivated, AEC-Q101-qualified standard rectifier diode in DO-201AD package, rated for 3A average forward current, 200V repetitive peak reverse voltage (V_RRM), and 125A non-repetitive surge current (I_FSM), used in DC-DC converters and switching-mode power supplies.

For engineers reviewing the 1N5402GHA0G datasheet, 1N5402GHA0G pinout, 1N5402GHA0G application, or 1N5402GHA0G equivalent, key selection criteria include V_RRM = 200 V, I_F = 3 A, V_F ≤ 1.0 V @ 3 A, thermal resistance R_θJA = 45 °C/W, and AEC-Q101 qualification for automotive-grade reliability.

Technical Context

This device is a single-die, silicon planar junction rectifier with glass passivation for enhanced moisture and contamination resistance. Its 200 V V_RRM rating targets mid-voltage industrial and automotive power conversion stages where moderate blocking capability and high surge tolerance are required.

The 1N5402GHA0G operates across –55 °C to +150 °C junction temperature range and exhibits 5 µA max reverse leakage at 25 °C and 100 µA at 125 °C, supporting stable performance in thermally demanding environments without derating below 75 °C ambient.

FAQ

What is the peak repetitive reverse voltage (V_RRM) rating for the 1N5402GHA0G?

The 1N5402GHA0G has a peak repetitive reverse voltage (V_RRM) rating of 200 V. This value is specified in the Absolute Maximum Ratings table and defines the maximum reverse-biased voltage the diode can block repeatedly without breakdown. It is distinct from the 1N5400G (50 V) and 1N5408G (1000 V) variants in the same family.

Is the 1N5402GHA0G AEC-Q101 qualified, and what does the "H" suffix indicate?

Yes, the 1N5402GHA0G is AEC-Q101 qualified. Per the Ordering Information section, the "H" in the part number denotes AEC-Q101 qualification, confirming that the device has passed stress tests including temperature cycling, highly accelerated life testing (HALT), and mechanical shock per automotive reliability standards.

What is the forward voltage (V_F) of the 1N5402GHA0G at rated current?

The 1N5402GHA0G has a maximum forward voltage (V_F) of 1.0 V at 3 A forward current and 25 °C junction temperature. This value is confirmed in the Electrical Specifications table for the 1N5402G through 1N5408G group and reflects its low-loss rectification capability.

What package type does the 1N5402GHA0G use, and how is polarity identified?

The 1N5402GHA0G uses the DO-201AD axial-leaded package. Polarity is identified by a cathode band marked on the body; the banded end is the cathode terminal, and the unmarked end is the anode. This marking aligns with JEDEC DO-201AD mechanical drawings and TSC's Marking Diagram.

Does the 1N5402GHA0G have a specified junction-to-case thermal resistance (R_θJC)?

Yes, the 1N5402GHA0G has a typical junction-to-case thermal resistance (R_θJC) of 15 °C/W, as published in the Thermal Performance section. This parameter enables thermal modeling when the diode is mounted to a heatsink or thermally conductive PCB pad via its axial leads.
