Product details

Overview

1N5393G R0G from Taiwan Semiconductor is a general-purpose silicon rectifier diode rated for 200 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 rectification.

For engineers reviewing the 1N5393G R0G datasheet, 1N5393G R0G pinout, 1N5393G R0G application, or 1N5393G R0G equivalent, key selection criteria include its DO-15 axial package, 1.5 A continuous rating with 30 A surge capability, thermal performance up to 150 °C, and compatibility with standard through-hole PCB layouts in offline power supplies.

Technical Context

This diode employs a planar passivated PN-junction structure optimized for high reliability in line-frequency rectification. Its 200 V V_RRM rating supports universal-input (85–265 V_AC) power supplies, while the 1.5 A I_F(AV) and 30 A I_FSM enable robust handling of inrush currents during cold-start conditions.

Thermal design is supported by a maximum junction-to-ambient thermal resistance (R_θJA) of 75 °C/W under standard PCB mounting, and the device maintains stable reverse leakage (I_R ≤ 5 µA at 200 V, T_J = 25 °C) across its full operating temperature range.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	200 V - Maximum repetitive reverse voltage before breakdown; sets safe operating limit for AC line rectification.
I_F(AV)	1.5 A - Average forward current rating at 75 °C case temperature; defines continuous DC output capability.
I_FSM	30 A - Non-repetitive peak surge current (8.3 ms half-sine); withstands cold-start inrush in SMPS front-ends.
V_F @ I_F = 1.5 A	1.2 V - Forward voltage drop; determines conduction loss and thermal dissipation in rectifier stage.
T_J Range	-55 °C to +150 °C - Operating junction temperature range; enables use in sealed or high-ambient industrial enclosures.
I_R @ V_R = 200 V	≤ 5 µA at 25 °C - Reverse leakage current; ensures minimal standby power loss in off-state.

Pinout & Package

1N5393G R0G is housed in a DO-15 axial-leaded plastic package (Ø3.6 mm × 25.4 mm min body length), with cathode indicated by a band on the body. Leads are tinned copper, suitable for wave or hand soldering.

Pin/Terminal	Circuit Role	Design Meaning
Anode (unbanded end)	Forward current entry point	Connects to AC source or transformer secondary; polarity must match input phase.
Cathode (banded end)	Forward current exit point	Connects to filter capacitor or load; band orientation critical for correct rectifier polarity.

Key Features

Feature	Design Value
High surge current rating	30 A I_FSM (8.3 ms) - Supports repeated cold-start cycles without degradation in power adapters.
Wide temperature operation	-55 °C to +150 °C T_J - Enables deployment in automotive under-hood or industrial control environments.
Low forward voltage	1.2 V V_F @ 1.5 A - Reduces conduction loss versus higher-V_F alternatives, improving efficiency in 12–24 V output supplies.
DO-15 mechanical standardization	Industry-standard axial package with 7.6 mm lead spacing - Ensures compatibility with legacy through-hole assembly lines and socketed test fixtures.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
1N5393RLG	Same electrical specs; tape-and-reel packaging (RLG) vs. bulk (R0G); identical DO-15 package and marking.	No functional difference; selected for automated pick-and-place rather than manual/hand-soldered assembly.	Choose 1N5393RLG for SMT-compatible feeders; 1N5393G R0G remains optimal for through-hole rework or low-volume prototyping.
STTH1L06	Higher V_RRM (600 V), lower V_F (0.95 V @ 1 A), but TO-220AC package - not pin-compatible.	Used in higher-voltage flyback or PFC stages where 200 V rating is insufficient.	Select STTH1L06 only when >200 V blocking or <1.0 V V_F is required; 1N5393G R0G is preferred for cost-sensitive 200 V line rectification.

Compared with 1N5393RLG, the 1N5393G R0G offers identical electrical performance in bulk packaging for manual or selective soldering processes; versus STTH1L06, it provides lower-cost, DO-15-compatible 200 V rectification without requiring board redesign or thermal pad layout changes.

FAQ

What is the peak repetitive reverse voltage rating of the 1N5393G R0G?

The 1N5393G R0G has a peak repetitive reverse voltage (V_RRM) rating of 200 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 -55 °C to +150 °C junction temperature range, making the 1N5393G R0G suitable for universal-input (85–265 V_AC) power supply designs.

Does the 1N5393G R0G meet RoHS requirements?

Yes, the 1N5393G R0G complies with RoHS Directive 2011/65/EU. The "G" suffix in the part number denotes green compound encapsulation, confirming lead-free terminations and halogen-free molding compound. Taiwan Semiconductor's official documentation and distributor certifications (e.g., Digi-Key, Mouser) confirm full RoHS compliance for this specific variant.

What is the forward voltage drop of the 1N5393G R0G at rated current?

The 1N5393G R0G 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 slightly with temperature but remains ≤1.4 V at 150 °C. The 1.2 V V_F directly impacts conduction loss and thermal design in rectifier applications using the 1N5393G R0G.

Can the 1N5393G R0G replace the 1N5392G in an existing design?

Yes, the 1N5393G R0G can directly replace the 1N5392G in most applications, as both share identical DO-15 packaging, pinout, and thermal characteristics. The key difference is V_RRM: 1N5392G is rated for 100 V, while the 1N5393G R0G is rated for 200 V. Substituting the 1N5393G R0G provides increased reverse voltage margin without layout or thermal changes.

What is the non-repetitive peak forward surge current rating for the 1N5393G R0G?

The 1N5393G R0G is rated for 30 A non-repetitive peak forward surge current (I_FSM) under an 8.3 ms half-sine waveform condition. This rating reflects its ability to survive transient inrush currents during power-up, such as those generated by transformer magnetizing current or bulk capacitor charging. The 1N5393G R0G maintains this rating across its full operating temperature range.
