Product details

Overview

1N5392G R0G 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 -65 °C to +175 °C junction temperature range, commonly used in AC/DC power supply input stages and low-frequency rectification.

For engineers reviewing the 1N5392G R0G datasheet, 1N5392G R0G pinout, 1N5392G R0G application, or 1N5392G R0G equivalent, key selection criteria include V_RRM, I_F(AV), thermal resistance (R_θJA ≈ 65 °C/W), surge capability, and DO-15 package compatibility with through-hole PCB layouts.

Technical Context

This diode employs a planar passivated PN-junction structure optimized for high reliability in line-frequency rectification. Its 1.5 A average forward current rating assumes case temperature ≤ 75 °C with adequate heatsinking, and its 30 A surge rating applies to 8.3 ms half-sine wave pulses per JEDEC JESD201.

The device exhibits typical reverse recovery time (t_rr) of 2 μs at I_F = 1.0 A, V_R = 30 V, and dI/dt = 20 A/μs - suitable for 50/60 Hz transformer-fed supplies but not recommended for high-frequency switching applications.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	100 V - Maximum allowable repetitive reverse voltage without breakdown; sets minimum insulation margin for 120 VAC input designs.
I_F(AV)	1.5 A - Continuous DC forward current at T_C = 75 °C; derates linearly to zero at 175 °C junction temperature.
I_FSM	30 A - Single half-sine surge current (8.3 ms); supports inrush limiting in unregulated linear power supplies.
V_F @ I_F = 1.5 A	1.2 V max - Forward voltage drop determines conduction loss (P_cond ≈ 1.8 W) and thermal design requirements.
T_J Range	-65 °C to +175 °C - Enables operation in industrial and automotive under-hood environments without derating.
R_θJA	65 °C/W - Junction-to-ambient thermal resistance in free-air; requires PCB copper area or heatsink for sustained 1.5 A operation.

Pinout & Package

1N5392G R0G is housed in a DO-15 axial leaded package (JEDEC DO-204AL), with cathode indicated by a band on the body. Leads are tinned and solderable per MIL-STD-202, Method 208.

Pin/Terminal	Circuit Role	Design Meaning
Anode (unbanded end)	Forward current entry point	Connected to AC source or transformer secondary; polarity must match circuit topology to avoid reverse conduction.
Cathode (banded end)	Forward current exit point	Connected to filter capacitor or load; band orientation must be verified during manual assembly and AOI inspection.

Key Features

Feature	Design Value
High surge current capability	30 A I_FSM enables robust handling of transformer inrush and cold-start surges in linear power supplies.
Wide operating temperature range	-65 °C to +175 °C junction rating supports deployment in extended-temperature industrial controls and automotive auxiliary systems.
Low forward voltage	1.2 V max V_F at 1.5 A reduces conduction losses and eases thermal management versus higher-V_F alternatives.
DO-15 mechanical standardization	Compatible with legacy through-hole tooling, wave soldering profiles, and automated insertion equipment per IPC-7351.

Equivalent & Alternatives

The following parts are listed as comparable options for similar general-purpose rectifier applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
1N5392RLG	Same electrical specs; lead-free (RoHS-compliant) termination and green compound; identical DO-15 package.	No functional difference; suitable for new designs requiring RoHS compliance.	Select 1N5392RLG when environmental compliance is mandatory and legacy 1N5392G R0G is unavailable.
1N4002GP	Lower V_RRM (100 V same), lower I_F(AV) (1.0 A), higher V_F (1.4 V), same DO-41 package (slightly smaller body).	Limited to ≤12 W continuous loads; less surge margin; unsuitable for 1.5 A sustained operation.	Choose 1N4002GP only for cost-sensitive, low-power replacements where 1.5 A rating is not required.

Compared with 1N5392RLG and 1N4002GP, the 1N5392G R0G offers optimal balance of surge robustness, thermal capability, and legacy compatibility in DO-15 form factor - critical for field-replaceable power supply repairs and long-lifecycle industrial equipment.

FAQ

What is the peak repetitive reverse voltage (V_RRM) rating for the 1N5392G R0G?

The 1N5392G R0G has a peak repetitive reverse voltage rating of 100 V. This specification defines the maximum AC or DC reverse voltage the diode can block repeatedly without avalanche breakdown. It provides a 2× safety margin above the 170 V peak of 120 VAC mains, making the 1N5392G R0G appropriate for primary-side rectification in low-power linear power supplies.

What is the maximum average forward current (I_F(AV)) for the 1N5392G R0G, and under what conditions?

The 1N5392G R0G is rated for 1.5 A average forward current at a case temperature of 75 °C. This rating assumes adequate PCB copper area or heatsinking to maintain thermal equilibrium. At higher ambient temperatures or without heatsinking, the current must be derated linearly to zero at 175 °C junction temperature, as specified in the 1N5392G R0G datasheet.

Does the 1N5392G R0G have a RoHS-compliant version, and how does it differ?

Yes, the 1N5392RLG is the RoHS-compliant variant of the 1N5392G R0G. It shares identical electrical specifications, DO-15 package dimensions, and thermal performance but uses lead-free terminations and green compound encapsulation. The 1N5392G R0G itself contains lead per exemption 7a and is intended for legacy or non-RoHS-restricted applications.

What is the non-repetitive peak forward surge current (I_FSM) for the 1N5392G R0G, and what waveform does it reference?

The 1N5392G R0G supports a non-repetitive peak forward surge current of 30 A. This rating applies specifically to an 8.3 ms single half-sine wave pulse, per JEDEC JESD201 standards. It reflects the device's ability to survive transformer inrush currents and cold-start surges common in linear power supplies using the 1N5392G R0G.

Can the 1N5392G R0G be used in high-frequency switching applications such as SMPS?

No, the 1N5392G R0G is not suitable for high-frequency switching applications like switch-mode power supplies. Its typical reverse recovery time (t_rr) is 2 μs - too slow for efficient operation above ~10 kHz. The 1N5392G R0G is engineered for 50/60 Hz line-frequency rectification; for SMPS, fast recovery or ultrafast diodes with t_rr < 100 ns are required instead of the 1N5392G R0G.
