Product details

Overview

1N5397G B0G 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 supply input stages and industrial power conversion.

For engineers reviewing the 1N5397G B0G datasheet, 1N5397G B0G pinout, 1N5397G B0G application, or 1N5397G B0G 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 unregulated linear supplies and transformer-coupled rectification circuits.

The device is designed for single-phase full-wave or half-wave 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 (1-inch² copper pad, 1.6 mm FR-4).

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	1000 V - Maximum repetitive reverse voltage before breakdown; defines safe operating limit in high-voltage AC line applications.
I_F(AV)	1.5 A - Average forward current rating at 75°C case temperature; determines continuous DC output capability.
V_F @ I_F=1.5A	1.2 V - Forward voltage drop at rated current; directly impacts conduction loss and thermal load in rectifier stage.
I_FSM	30 A - Non-repetitive peak surge current (8.3 ms half-sine); supports inrush tolerance during cold-start of capacitive-input supplies.
T_J Range	-65°C to +175°C - Operating junction temperature range; enables use in industrial and automotive under-hood environments.
R_θJA	65°C/W - Junction-to-ambient thermal resistance; guides minimum PCB copper area and airflow requirements for thermal design.

Pinout & Package

Package: DO-15 molded plastic case with axial leads. Dimensions: 5.8 mm body diameter, 25.4 mm minimum lead length, 3.6 mm body length, 0.9 mm lead diameter. RoHS-compliant green compound encapsulation.

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
STTH1L06S	600 V V_RRM, 1 A I_F(AV), TO-220AC package, faster recovery (t_rr = 50 ns)	Limited to lower-voltage AC inputs; requires heatsink for >0.5 A continuous operation	Select when fast switching and higher thermal dissipation are needed, not for 1000 V line applications.
1N5408	1000 V V_RRM, 3 A I_F(AV), same DO-15 package, higher V_F (1.5 V @ 3 A)	Higher current capacity but larger forward loss at rated load; identical mounting footprint	Choose when system requires >1.5 A average current and can accommodate higher conduction loss.

Compared with STTH1L06S and 1N5408, the 1N5397G B0G offers optimal balance of 1000 V rating, 1.5 A capacity, and DO-15 form factor for cost-sensitive, space-constrained AC/DC inputs where ultrafast recovery is unnecessary.
