Product details

Overview

1N5392GHR0G from Taiwan Semiconductor is a general-purpose silicon rectifier diode rated for 100 V peak repetitive reverse voltage (V_RRM), 1.5 A average forward current (I_F(AV)), and 30 A non-repetitive peak forward surge current (I_FSM). It operates across –55 °C to +150 °C junction temperature and is used in AC/DC power supply input stages, battery charger front-ends, and low-frequency rectification circuits.

For engineers reviewing the 1N5392GHR0G datasheet, 1N5392GHR0G pinout, 1N5392GHR0G application, or 1N5392GHR0G equivalent, key selection criteria include its 1.1 V typical forward voltage at 1.5 A, 5 µA maximum reverse leakage at 100 V, DO-15 axial package mechanical compatibility, and thermal performance under 1% duty-cycle surge conditions.

Technical Context

This diode belongs to the 1N5391G–1N5399G family of standard recovery rectifiers with soft recovery characteristics. Its 1.5 A I_F(AV) rating assumes 75 °C ambient with free-air convection and a 40 °C/W thermal resistance (R_θJA) in DO-15 package.

Electrical behavior is characterized at T_J = 25 °C unless otherwise specified, with derating curves provided for reverse leakage (I_R), forward voltage (V_F), and surge capability up to 150 °C junction temperature.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	100 V - Maximum allowable repetitive reverse voltage before breakdown; defines safe AC input voltage headroom.
I_F(AV)	1.5 A - Continuous DC forward current rating at 75 °C ambient; determines heatsinking requirements.
V_F @ 1.5 A	1.1 V typical - Forward voltage drop at rated current; directly impacts conduction loss and thermal load.
I_R @ 100 V	5 µA max at 25 °C - Reverse leakage current; critical for low-power standby and high-impedance bias networks.
I_FSM	30 A - Non-repetitive surge current (8.3 ms half-sine); supports inrush current handling in transformer-fed supplies.
T_J Range	–55 °C to +150 °C - Operating junction temperature range; enables use in automotive under-hood and industrial environments.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
1N5392RLG	Same electrical specs; DO-15 package with lead-free matte tin plating and different date-code format.	No functional difference; identical thermal and surge performance.	Select when lead-free assembly or specific tape-and-reel packaging is required.
STTH1L06U	Ultrafast recovery (≈75 ns), lower V_F (0.95 V), but lower I_F(AV) (1.0 A) and V_RRM (600 V).	Suitable for higher-frequency SMPS secondaries; not recommended for 50/60 Hz primary rectification due to lower I_F(AV).	Choose only if switching frequency exceeds 20 kHz and lower conduction loss outweighs reduced surge margin.

Compared with 1N5392GHR0G, 1N5392RLG offers identical rectification performance with alternate packaging compliance, while STTH1L06U trades surge robustness and line-frequency suitability for faster switching and lower forward loss in high-frequency designs.

FAQ

What is the peak repetitive reverse voltage (V_RRM) rating of the 1N5392GHR0G?

The 1N5392GHR0G has a peak repetitive reverse voltage rating of 100 V. This value defines the maximum AC or DC reverse voltage the diode can block repeatedly without breakdown. It is measured under standard test conditions (T_J = 25 °C) and must be derated at elevated junction temperatures per the manufacturer's thermal curves. Designers should maintain at least 20% margin below this rating in 50/60 Hz applications to accommodate line transients and transformer regulation.

Does the 1N5392GHR0G have a halogen-free package?

Yes, the 1N5392GHR0G uses green compound encapsulation, which is halogen-free and RoHS-compliant per the "G" marking code in its designation. The package material meets IEC 61249-2-21 requirements for bromine and chlorine content, making it suitable for environmentally regulated markets including EU and China RoHS. This applies to all units marked with "G" suffix in the 1N5391G–1N5399G family.

What is the forward voltage drop (V_F) of the 1N5392GHR0G at its rated current?

The 1N5392GHR0G exhibits a typical forward voltage drop of 1.1 V at 1.5 A DC forward current and 25 °C junction temperature. This value increases to approximately 1.25 V at 150 °C. V_F directly determines conduction losses (P_cond = I_F × V_F) and influences thermal design-especially in high-ambient environments where self-heating raises T_J.

Can the 1N5392GHR0G replace the 1N4002 in a design?

No, the 1N5392GHR0G is not a direct replacement for the 1N4002. While both are DO-15 rectifiers, the 1N4002 is rated for only 100 V V_RRM and 1.0 A I_F(AV), whereas the 1N5392GHR0G supports 1.5 A I_F(AV) with identical V_RRM. Substituting upward is acceptable if board layout and thermal design accommodate the higher current, but the 1N5392GHR0G must not be used where the 1N4002's lower surge rating or tighter V_F tolerance is relied upon.

What is the maximum non-repetitive peak forward surge current (I_FSM) for the 1N5392GHR0G?

The 1N5392GHR0G is rated for a maximum non-repetitive peak forward surge current (I_FSM) of 30 A, tested using an 8.3 ms single half-sine wave. This rating applies under specified pulse conditions (300 µs pulse width, 1% duty cycle) and is critical for surviving cold-start inrush in transformer-fed supplies. Exceeding this value-even briefly-may cause permanent junction damage.
