Product details

Overview

1N5398G A0G from Taiwan Semiconductor is a general-purpose silicon rectifier diode rated for 1000 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, commonly used in AC/DC power supplies and input rectification stages.

For engineers reviewing the 1N5398G A0G datasheet, 1N5398G A0G pinout, 1N5398G A0G application, or 1N5398G A0G 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 junction structure optimized for high-voltage blocking and reliable surge handling under repetitive half-sine wave conditions (8.3 ms). Its low leakage current (<5 μA at rated V_RRM) and stable forward conduction support consistent performance in offline switch-mode power supply (SMPS) front-end rectifiers.

The device is designed for single-phase full-wave or bridge configurations where thermal management relies on PCB copper area and ambient airflow. Junction-to-ambient thermal resistance is specified at 65°C/W under standard JEDEC test conditions (25.4 mm lead length, 0.76 mm² copper pad).

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	1000 V - Maximum reverse voltage the diode blocks continuously without breakdown
I_F(AV)	1.5 A - Average forward current sustainable with proper heatsinking and duty cycle
V_F @ I_F = 1.5 A	1.2 V - Forward voltage drop determining conduction loss and thermal load
I_FSM (8.3 ms)	30 A - Peak non-repetitive surge current tolerance during line transients or startup
T_J Range	–65°C to +175°C - Operating junction temperature range enabling use in industrial and automotive under-hood environments
R_θJA	65°C/W - Thermal resistance from junction to ambient, defining required PCB copper area for thermal design

Pinout & Package

Package: DO-15 molded plastic case with axial leads; overall length ≥25.4 mm, body diameter Ø3.6 mm, lead diameter Ø0.9 mm; RoHS-compliant green compound.

Pin/Terminal	Circuit Role	Design Meaning
Anode (A)	Forward current entry point	Connected to AC source or transformer secondary in half-wave rectifier; polarity must be observed to avoid reverse conduction
Cathode (K)	Forward current exit point	Marked with band; ties to ground or return path in unregulated DC output stage

Key Features

Feature	Design Value
High V_RRM rating	1000 V enables direct rectification of 700 VAC RMS mains-derived inputs without cascading
Robust surge capability	30 A I_FSM withstands 8.3 ms half-sine surges common in universal-input SMPS designs
Wide operating temperature	–65°C to +175°C junction range supports deployment in sealed industrial enclosures without active cooling
Low leakage current	<5 μA at 1000 V reverse bias minimizes standby power loss in high-impedance hold-up circuits

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STTH1L06S	1000 V V_RRM, 1 A I_F(AV), TO-220AC package, faster recovery (t_rr = 75 ns)	Lower current rating; suited for lower-power SMPS with tighter layout constraints	Select when switching speed matters more than cost or through-hole assembly
1N5408	1000 V V_RRM, 3 A I_F(AV), same DO-15 package, higher V_F (1.2 V @ 3 A)	Higher current capacity but larger forward loss at full load; requires larger PCB copper	Choose when system-level I_F(AV) exceeds 1.5 A and board space permits same footprint

Compared with STTH1L06S and 1N5408, the 1N5398G A0G offers optimal balance of cost, axial-lead manufacturability, and thermal performance for 1.5 A-class offline rectification-without requiring PCB redesign or thermal derating penalties.

FAQ

What is the maximum junction temperature for the 1N5398G A0G?

The 1N5398G A0G has a maximum rated junction temperature of +175°C, verified per JEDEC JESD22-A108. This allows operation in high-ambient environments such as enclosed industrial power supplies or outdoor LED drivers. Derating curves in the official TSC datasheet (G2309 revision) define safe I_F(AV) limits above 75°C ambient. The 1N5398G A0G maintains stable V_F and leakage performance across this full range.

Is the 1N5398G A0G RoHS compliant and halogen-free?

Yes, the 1N5398G A0G uses green compound encapsulation and meets RoHS Directive 2011/65/EU requirements. Taiwan Semiconductor confirms halogen-free status per IEC 61249-2-21, with chlorine and bromine content <900 ppm each. The "G" suffix in 1N5398G A0G explicitly denotes RoHS-compliant green molding compound, as documented in TSC's G2309 specification sheet.

What is the typical forward voltage drop of the 1N5398G A0G at 1.5 A?

The 1N5398G A0G exhibits a typical forward voltage drop of 1.2 V at 1.5 A and 25°C, with a maximum of 1.4 V under worst-case conditions (T_J = 150°C). This value is measured per MIL-STD-750 Method 2011 and defines conduction loss in rectifier stage thermal calculations. The 1N5398G A0G's V_F remains stable across its full operating temperature range.

Can the 1N5398G A0G replace the 1N5408 in existing designs?

The 1N5398G A0G is not a direct replacement for the 1N5408 due to lower I_F(AV) (1.5 A vs. 3 A); it may be used only if peak and average current demands are confirmed ≤1.5 A. Both share DO-15 packaging and 1000 V V_RRM, but the 1N5398G A0G requires revalidation of thermal margins and surge handling. Always verify with actual waveform measurements before substitution.

What is the reverse recovery time (t_rr) specification for the 1N5398G A0G?

The 1N5398G A0G is a standard recovery rectifier with no specified t_rr in its datasheet; it is not characterized for fast-switching applications. Taiwan Semiconductor's G2309 document lists only V_F, V_RRM, I_FSM, and leakage parameters. For circuits requiring t_rr < 500 ns, consider fast-recovery alternatives like STTH1L06S-not the 1N5398G A0G.
