Taiwan Semiconductor Corporation 1N5392G

Overview

1N5392G 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 features a maximum forward voltage drop of 1.2 V at 1.5 A and operates across -55 °C to +150 °C junction temperature, commonly used in AC/DC power supply input stages and low-frequency bridge rectifiers.

For engineers reviewing the 1N5392G datasheet, 1N5392G pinout, 1N5392G application, or 1N5392G equivalent, key selection criteria include its DO-15 axial package, 100 V V_RRM, 1.5 A I_F(AV), thermal performance up to 150 °C, and compatibility with standard through-hole PCB layouts in industrial power supplies and consumer adapters.

Technical Context

The 1N5392G is a single-junction, planar-diffused silicon PN rectifier designed for low-to-medium frequency (<1 kHz) AC line rectification. Its construction enables stable operation under repetitive surge conditions (8.3 ms half-sine wave) and maintains low leakage current (<5 µA at 100 V, T_J = 25 °C).

Thermal design relies on its DO-15 package's 50 °C/W junction-to-ambient thermal resistance (R_θJA) when mounted on FR-4 PCB with 25.4 mm lead length. The device exhibits typical reverse recovery time (t_rr) > 2 µs, confirming suitability for non-switching, line-frequency applications only.

Key Specifications

FAQ

What is the peak repetitive reverse voltage rating of the 1N5392G?

The 1N5392G has a peak repetitive reverse voltage (V_RRM) rating of 100 V. This specification defines the maximum AC or DC reverse voltage the diode can block repeatedly without breakdown. It is validated per JEDEC standards and applies across the full operating temperature range from -55 °C to +150 °C. Designers must ensure that peak inverse voltage in the circuit-including line surges and ringing-stays below this limit to prevent catastrophic failure of the 1N5392G.

Can the 1N5392G be used in place of the 1N4002 in a power supply design?

The 1N5392G shares the same 100 V V_RRM as the 1N4002 but offers higher average forward current (1.5 A vs. 1.0 A) and greater surge capability (30 A vs. 18 A). While electrically compatible in many 1N4002 applications, the 1N5392G provides additional margin for sustained load or inrush conditions. However, verify thermal dissipation and PCB layout compatibility, as both use DO-15 but may differ slightly in lead pitch and body dimensions.

What is the maximum junction temperature for continuous operation of the 1N5392G?

The 1N5392G is rated for continuous operation up to a maximum junction temperature (T_J) of +150 °C. This rating is confirmed under specified test conditions per Taiwan Semiconductor's datasheet revision G2309. To maintain reliability, designers must calculate actual junction temperature using R_θJA = 50 °C/W (DO-15, 25.4 mm leads) and ensure that power dissipation-derived from V_F × I_F-does not cause T_J to exceed 150 °C under worst-case ambient and airflow conditions.

Does the 1N5392G meet RoHS and halogen-free requirements?

Yes, the 1N5392G uses green compound encapsulation, which is halogen-free and compliant with EU RoHS Directive 2011/65/EU. The "G" suffix in the part number explicitly denotes this environmentally compliant molding material. Full substance declarations and test reports are available from Taiwan Semiconductor upon request, and the 1N5392G is suitable for use in consumer electronics and industrial equipment requiring strict chemical compliance.

What is the forward voltage drop of the 1N5392G at its rated current?

The 1N5392G exhibits a maximum forward voltage drop (V_F) of 1.2 V at 1.5 A DC forward current and 25 °C junction temperature. This value increases with temperature and current-e.g., ~1.1 V at 1.0 A and ~1.3 V at 150 °C. Designers should use this parameter to compute conduction losses (P_cond = V_F × I_F) and size heatsinking or derate current accordingly in thermally constrained applications using the 1N5392G.
