Product details

Overview

1N5398GHB0G 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 -55°C to +150°C junction temperature, commonly used in AC/DC power supplies and input rectification stages.

For engineers reviewing the 1N5398GHB0G datasheet, 1N5398GHB0G pinout, 1N5398GHB0G application, or 1N5398GHB0G equivalent, key selection criteria include V_RRM, I_F(AV), thermal resistance (R_θJA = 50°C/W), surge capability, and DO-15 package compatibility with board-level heat dissipation requirements.

Technical Context

This diode employs a planar passivated PN junction structure optimized for high-voltage blocking and moderate-current rectification. Its 1000 V V_RRM rating supports universal-input offline SMPS front-end designs, while the 30 A I_FSM (8.3 ms half-sine) enables robust handling of inrush and transient surges without derating.

Thermal performance is defined by R_θJA = 50°C/W (PCB-mounted, 1-inch² copper pad), and reverse recovery time (t_rr) is not specified in the family datasheet - confirming it is intended for 50/60 Hz and low-frequency (<1 kHz) rectification, not fast-switching applications.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	1000 V - Supports rectification in 230 VAC mains-derived circuits with safety margin.
I_F(AV)	1.5 A - Sustained DC output current capability under natural convection cooling.
V_F @ I_F = 1.5 A	1.2 V max - Contributes ≤1.8 W conduction loss at full load; impacts thermal design.
I_FSM	30 A (8.3 ms) - Withstands cold-start inrush in transformer-based power supplies.
T_J Range	-55°C to +150°C - Enables operation in industrial and automotive under-hood environments.
R_θJA	50°C/W - Requires ≥1-inch² copper pour for safe 1.5 A operation at 70°C ambient.

Pinout & Package

1N5398GHB0G is housed in a DO-15 axial leaded package (Ø3.6 mm × 25.4 mm min body length), with cathode indicated by a band on the body. Leads are tinned and suitable for wave or hand soldering.

Key Features

Feature	Design Value

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
1N5408	Same DO-15 package; 1000 V V_RRM, 3 A I_F(AV), higher V_F (1.2 V @ 3 A)	Higher current capacity but larger thermal footprint; less efficient at 1.5 A due to higher R_DS(on)-like behavior	Select 1N5408 only when >1.5 A average current or higher surge margin is required.
STTH1L06	TO-220AC package; 600 V V_RRM, 1 A I_F(AV), fast recovery (≤75 ns)	Not suitable for 230 VAC rectification; intended for high-frequency secondary-side rectification	Choose STTH1L06 only for low-voltage, high-frequency DC-DC outputs - not as a substitute for 1N5398GHB0G.

Compared with 1N5408 and STTH1L06, the 1N5398GHB0G offers optimal balance of voltage rating, current capability, and thermal efficiency in cost-sensitive, low-to-moderate frequency AC-DC front ends where fast recovery is unnecessary.

FAQ

What is the peak repetitive reverse voltage (V_RRM) of the 1N5398GHB0G?

The 1N5398GHB0G has a peak repetitive reverse voltage (V_RRM) rating of 1000 V. This specification ensures reliable blocking of reverse voltage in 230 VAC line applications with sufficient safety margin against transients. The value is confirmed in the official Taiwan Semiconductor datasheet for the 1N5391G–1N5399G family and applies directly to the 1N5398GHB0G variant.

What is the maximum average forward current (I_F(AV)) for the 1N5398GHB0G?

The 1N5398GHB0G supports a maximum average forward current (I_F(AV)) of 1.5 A at case temperature ≤70°C with adequate PCB copper area. This rating assumes natural convection cooling and is validated per JEDEC test conditions using a 1-inch² copper pad. Exceeding this current without thermal enhancement risks junction overheating and premature failure.

Does the 1N5398GHB0G have a specified reverse recovery time (t_rr)?

No, the 1N5398GHB0G does not specify reverse recovery time (t_rr) in its official datasheet. This omission confirms its classification as a general-purpose rectifier optimized for 50/60 Hz and low-frequency (<1 kHz) applications - not for high-frequency switching. Engineers should avoid using the 1N5398GHB0G in flyback or resonant converter secondary-side rectification where fast recovery is required.

What package type is used for the 1N5398GHB0G?

The 1N5398GHB0G uses the DO-15 axial-leaded package, with dimensions of Ø3.6 mm body diameter and minimum 25.4 mm body length. Cathode identification is marked by a single band near one lead. This standardized through-hole package ensures compatibility with legacy 1N400x and 1N540x footprints and automated insertion equipment.

What is the surge current rating (I_FSM) of the 1N5398GHB0G and how is it tested?

The 1N5398GHB0G has a non-repetitive peak forward surge current (I_FSM) rating of 30 A, tested using an 8.3 ms single half-sine waveform per IEC 61000-4-5. This rating reflects real-world inrush and lightning-induced surge events. The 1N5398GHB0G can withstand this stress without degradation when mounted on a standard PCB with appropriate copper area, eliminating the need for additional surge-limiting components in many designs.
