Product details

Overview

1N5402GHR0G from Taiwan Semiconductor is a glass-passivated, single-die standard rectifier diode rated for 3 A average forward current and 200 V repetitive peak reverse voltage (V_RRM), with 125 A surge capability and 1.0 V max forward voltage at 3 A - used in DC-DC converters and switching-mode power supplies.

For engineers reviewing the 1N5402GHR0G datasheet, 1N5402GHR0G pinout, 1N5402GHR0G application, or 1N5402GHR0G equivalent, key selection criteria include V_RRM = 200 V, I_F = 3 A, V_F ≤ 1.0 V @ 3 A, DO-201AD package, and AEC-Q101 qualification status (indicated by "H" suffix).

Technical Context

This device operates as a unidirectional silicon junction rectifier with glass-passivated chip construction for enhanced moisture resistance and long-term reliability. Its thermal design supports 150 °C maximum junction temperature and delivers 45 °C/W junction-to-ambient thermal resistance in the DO-201AD package.

The 1N5402GHR0G exhibits low leakage (≤5 µA @ 25 °C, ≤100 µA @ 125 °C) and 25 pF junction capacitance at 4 V reverse bias, enabling stable performance in high-frequency switching applications up to several hundred kHz.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STTH3L02S	3 A, 200 V, TO-220AC package, 0.95 V V_F, 50 ns t_rr	Designed for higher-speed switching; faster recovery reduces ringing in high-frequency topologies	Preferred when layout allows TO-220 mounting and <50 ns reverse recovery is required
ON Semi MUR320	3 A, 200 V, DO-201AD, 0.92 V V_F, 50 ns t_rr, not AEC-Q101 qualified	Ultrafast recovery enables use in PFC stages; lacks automotive qualification	Select when fast recovery is critical and automotive compliance is not required

Compared with STTH3L02S and MUR320, the 1N5402GHR0G trades slightly higher V_F and slower recovery for AEC-Q101 validation and proven ruggedness in cost-sensitive, thermally demanding rectifier roles - ideal where reliability outweighs speed.

FAQ

What is the peak repetitive reverse voltage rating for the 1N5402GHR0G?

The 1N5402GHR0G has a repetitive peak reverse voltage (V_RRM) rating of 200 V. This value is specified in the Absolute Maximum Ratings table and defines the highest reverse voltage the diode can block repeatedly without breakdown under normal operating conditions. It is distinct from VR(RMS) (140 V) and must be respected with appropriate derating in designs exposed to voltage transients.

Does the 1N5402GHR0G meet automotive qualification standards?

Yes, the "H" in 1N5402GHR0G indicates AEC-Q101 qualification. This means the 1N5402GHR0G has undergone stress testing including high-temperature operating life (HTOL), temperature cycling (TC), and high-temperature reverse bias (HTRB) per the AEC-Q101 standard, making it suitable for automotive under-hood applications where reliability under thermal and mechanical stress is critical.

What is the forward voltage drop of the 1N5402GHR0G at its rated current?

The 1N5402GHR0G 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 and reflects conduction loss under typical operating conditions - lower than the 1.1 V spec for 1N5400G/1N5401G variants due to optimized die structure.

Which package type does the 1N5402GHR0G use, and what are its key mechanical properties?

The 1N5402GHR0G uses the DO-201AD package: an axial-leaded, molded plastic case with glass-passivated chip and cathode band polarity marking. Key properties include UL 94V-0 flammability rating, pure tin-plated leads compliant with J-STD-002, JESD201 Class 2 whisker resistance, and approximate weight of 1.20 g.

How does the 1N5402GHR0G compare to the 1N5408G in terms of voltage rating and application scope?

The 1N5402GHR0G is rated for 200 V V_RRM, whereas the 1N5408G is rated for 1000 V. This makes the 1N5402GHR0G suitable for lower-voltage applications like 12–24 V DC-DC outputs or 100 V AC rectification, while the 1N5408G targets high-voltage industrial or telecom power supplies. Both share identical current, thermal, and packaging specs - only V_RRM and related parameters differ across the 1N540xG family.
