Product details
Overview
S1G-13 from Diodes Incorporated is a 1.0A surface-mount glass passivated silicon rectifier diode in SMA package, rated for 400V peak repetitive reverse voltage (VRRM), 1.1V forward voltage at 1.0A (VFM), and 30A non-repetitive surge current (IFSM); used in AC/DC input stage rectification of offline power supplies and auxiliary power rails.
For engineers reviewing the S1G-13 datasheet, S1G-13 pinout, S1G-13 application, or S1G-13 equivalent, key selection criteria include VRRM derating for capacitive loads, thermal resistance (RJT = 30°C/W) under PCB copper pad heatsinking, and RoHS-compliant lead-free plating per EU Directive Annex Notes 5 & 7.
Technical Context
This device operates as a single-phase, half-wave rectifier for 60Hz line-frequency applications with resistive or inductive loads; capacitive loads require 20% average current derating per datasheet guidance. Its glass passivated die construction ensures stable reverse leakage performance across -65°C to +150°C operating range.
Reverse recovery time is specified at 2.0μs under IF = 0.5A, IR = 1.0A, IRR = 0.25A test conditions, and typical junction-to-terminal thermal resistance is measured with 5.0mm² × 0.013mm copper pads acting as heatsink per JESD51-2.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 400 V - Maximum peak reverse voltage the diode blocks without breakdown during normal operation |
| IO @ TT=100°C | 1.0 A - Average rectified output current sustainable with terminal temperature held at 100°C |
| VFM @ IF=1.0A | 1.1 V - Forward voltage drop determining conduction loss and thermal dissipation in linear rectifier stage |
| IFSM (8.3ms) | 30 A - Peak surge current capability enabling survival through AC line transients and inrush events |
| trr | 2.0 μs - Reverse recovery time affecting switching loss and EMI in higher-frequency rectifier designs |
| RJT | 30 °C/W - Thermal resistance from junction to terminal, defining required PCB copper area for thermal management |
| IRM @ 125°C | 100 μA - Maximum reverse leakage at elevated temperature, critical for standby power budgeting |
Pinout & Package
Package: SMA (Surface Mount Adapter), molded plastic case per UL 94V-0, moisture sensitivity level 1 per J-STD-020C; cathode identified by band marking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

Key Features
| Feature | Design Value |
|---|---|
| Glass passivated die construction | Enables stable long-term reliability and low parameter drift under thermal cycling and humidity exposure |
| Low forward voltage drop (1.1V @ 1A) | Reduces conduction loss and improves efficiency in low-voltage, high-current rectifier stages |
| 30A surge rating (8.3ms half-sine) | Supports robust operation during cold-start inrush and AC line fault transients without failure |
| RoHS-compliant lead-free finish | Meets EU Directive Annex Notes 5 & 7 exemptions for glass and high-temp solder; suitable for modern assembly |
Applications
| AC/DC Power Adapter Input Stage | Industrial Control Auxiliary Supply |
|---|---|
Use Scenario: Rectifying 120/230VAC mains input into DC bus for isolated flyback or buck-derived auxiliary rails. IC Role / Device Role / Timing Role: Primary rectifier in single-phase half-wave configuration feeding bulk capacitor. Use Value: 400V VRRM provides 2× safety margin over 230VAC RMS; 1.0A IO supports up to 5W auxiliary output with adequate derating. | Use Scenario: Generating +12V or +24V bias supply for PLC I/O modules and sensor interface circuitry. IC Role / Device Role / Timing Role: Off-line rectifier feeding linear regulator or low-power SMPS controller. Use Value: 30°C/W RJT enables thermal stability on standard FR4 with minimal copper; 100μA IRM at 125°C limits standby leakage. |
| LED Driver Primary Rectification | Appliance Standby Power Supply |
Use Scenario: Converting AC line to DC for constant-current LED driver ICs in residential/commercial lighting. IC Role / Device Role / Timing Role: Input-stage rectifier preceding PFC or non-isolated buck topology. Use Value: 2.0μs trr minimizes switching loss when driven by high-frequency ripple; glass passivation ensures lifetime >50,000 hours. | Use Scenario: Providing always-on 3.3V/5V rail for remote control receivers and real-time clocks in white goods. IC Role / Device Role / Timing Role: Half-wave rectifier feeding low-quiescent LDO or charge-pump converter. Use Value: 1.1V VFM reduces no-load power draw; RoHS-compliant finish satisfies global regulatory requirements. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar rectifier diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor MUR140 | Ultrafast recovery (trr = 50ns), higher VRRM (400V), same IO (1A), DO-41 package | Preferred where reduced EMI and higher switching frequency operation required | Select for SMPS input stages needing faster recovery; not drop-in due to through-hole package |
| Vishay VS-1N4007TR | Standard recovery (trr > 2μs), same VRRM (1000V), same IO (1A), DO-41 package, higher IRM | Used in cost-sensitive, low-frequency, non-critical rectification where surge margin is primary concern | Select for legacy designs or where 1000V VRRM margin justifies higher VFM (1.1V vs 1.0V typical) |
Compared with S1G-13, MUR140 offers superior dynamic performance but requires board redesign for through-hole mounting, while VS-1N4007TR trades lower cost and higher voltage margin for higher leakage and less thermal efficiency in surface-mount layouts.

FAQ
What is the maximum allowable terminal temperature for continuous operation of S1G-13?
The datasheet specifies IO = 1.0A at TT = 100°C, meaning the terminal temperature must not exceed 100°C under full-rated DC load. Derating curves show usable current drops to ~0.6A at 125°C terminal temperature, with absolute maximum junction temperature limited to +150°C.
Can S1G-13 be used in full-wave bridge configurations?
Yes - S1G-13 is a single diode intended for use in discrete full-wave bridge assemblies. Four S1G-13 units can form a compact surface-mount bridge; however, its 400V VRRM limits use to ≤280VAC RMS inputs unless additional voltage margin is applied per design standards.
Is the S1G-13 RoHS-compliant version identical in electrical performance to the standard version?
Yes - the "-13" suffix denotes Diodes Incorporated's RoHS-compliant lead-free finish (matte tin plating), with identical VRRM, VFM, IFSM, and thermal characteristics as the non-RoHS variant; only the termination plating differs per EU Directive Annex Notes 5 & 7 exemptions.
How does capacitive load affect S1G-13 current rating?
Per datasheet Note: "For capacitive load, derate current by 20%." This means the average rectified current must be limited to 0.8A instead of 1.0A to prevent excessive peak charging currents that accelerate thermal stress and reduce reliability in capacitor-input filter designs.
