Product details
Overview
S1GB-13 from Diodes Incorporated is a surface-mount, glass-passivated general-purpose silicon rectifier diode in SMB package, rated for 400 V peak repetitive reverse voltage (VRRM), 1.0 A average forward current (IO) at 100°C terminal temperature, and 30 A non-repetitive surge current (IFSM); used for AC/DC conversion in offline power supplies and auxiliary rail generation.
For engineers reviewing the S1GB-13 datasheet, S1GB-13 pinout, S1GB-13 application, or S1GB-13 equivalent, key selection criteria include VRRM rating, forward voltage drop at 1.0 A, thermal resistance (RθJT = 30 °C/W), reverse recovery time (trr = 1.8–3.0 µs), and SMB package compatibility with automated PCB assembly.
Technical Context
This device operates as a unidirectional, single-phase, half-wave rectifier under resistive or inductive loads at 60 Hz. It exhibits low forward voltage (VFM ≤ 1.1 V @ IF = 1.0 A) and tight reverse leakage control (IRM ≤ 5.0 µA @ 25°C, ≤ 100 µA @ 125°C).
Its fast recovery characteristic (trr = 1.8–3.0 µs) supports moderate-frequency switching applications, while its glass-passivated die construction ensures robustness against moisture and mechanical stress per J-STD-020 Level 1 MSL rating.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 400 V - Maximum peak reverse voltage before breakdown; defines safe AC input handling up to ~280 V RMS. |
| IO | 1.0 A @ TT = +100°C - Continuous DC output current capability with adequate PCB copper heatsinking. |
| VFM | ≤ 1.1 V @ IF = 1.0 A - Low conduction loss enabling >85% efficiency in low-voltage secondary-side rectification. |
| IFSM | 30 A (8.3 ms half-sine) - Withstands inrush surges from capacitor-input filters without failure. |
| trr | 1.8–3.0 µs - Enables use in 20–50 kHz flyback and forward converters without excessive switching loss. |
| RθJT | 30 °C/W - Junction-to-terminal thermal resistance measured on 5 mm² copper pad; guides heatsink design. |
| IRM | ≤ 5.0 µA @ 25°C, ≤ 100 µA @ 125°C - Low leakage preserves no-load regulation and reduces standby power. |
Pinout & Package
Package: SMB (Surface-Mount Body), molded plastic case compliant with UL 94V-0; cathode indicated by band on top surface; lead-free matte tin terminals solderable per MIL-STD-202 Method 208.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to AC source or transformer secondary; must withstand full surge current and reverse voltage transients. |
| Cathode | Forward current exit point | Connected to output filter capacitor; polarity marking (band) prevents reverse installation during automated placement. |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated die construction | Eliminates need for hermetic sealing; achieves >10⁸ hour reliability under 85°C/85% RH per JEDEC JESD22-A101. |
| Surge rating: 30 A IFSM | Supports direct rectification of 120/230 VAC inputs with bulk capacitance ≥ 22 µF without derating. |
| RoHS-compliant & halogen-free | Meets EU Directive 2011/65/EU and IPC-1752A Class 1; Br+Cl < 1500 ppm, Sb < 1000 ppm. |
| MSL Level 1 rating | Zero bake requirement prior to reflow; compatible with standard SMT lines without dry pack or floor-life controls. |
Applications
| AC-DC Adapter Power Supply | Industrial Control Auxiliary Rail |
|---|---|
Use Scenario: Rectifying 12–24 VAC transformer secondaries in wall-wart adapters delivering 5–12 VDC at ≤1 A. IC Role / Device Role: Primary output rectifier in low-cost, non-isolated linear or flyback-derived supplies. Use Value: VFM ≤ 1.1 V minimizes heat rise on compact PCBs; SMB footprint enables high-density layout. | Use Scenario: Generating isolated 3.3 V or 5 V bias rails for PLC I/O modules and sensor interfaces. IC Role / Device Role: Secondary-side rectifier feeding LDO or buck converter input. Use Value: 400 V VRRM provides margin against line transients; trr < 3.0 µs avoids cross-conduction in synchronous designs. |
| LED Driver Input Stage | Appliance Motor Control Board |
Use Scenario: Bridge rectification in constant-current LED drivers powering commercial downlights (20–40 W). IC Role / Device Role: One leg of full-wave bridge (S1GB-13 ×4) converting 120/230 VAC to pulsating DC. Use Value: 30 A IFSM handles cold-start surge into large electrolytic; RθJT = 30 °C/W enables thermal coupling to ground plane. | Use Scenario: Providing DC bus for H-bridge gate drivers in washing machine motor control boards. IC Role / Device Role: Freewheeling path for inductive kickback during PWM commutation. Use Value: Fast trr limits voltage overshoot across MOSFETs; low IRM prevents false triggering of overvoltage protection. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar general-purpose rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor MUR140 | Ultrafast recovery (trr ≈ 50 ns), higher VRRM (400 V), same IO (1 A), DO-41 through-hole package | Requires wave solder or hand assembly; unsuitable for high-density SMT layouts | Select when ultrafast switching is critical and board space allows through-hole mounting. |
| Vishay VS-1N4007TR | Standard recovery (trr > 2 µs), same VRRM (1000 V), same IO (1 A), DO-41 package, lower cost | Larger footprint, no MSL Level 1 rating, not RoHS/halogen-free certified | Select for cost-sensitive, non-automated, non-green compliance applications with ample board area. |
Compared with MUR140 and VS-1N4007TR, S1GB-13 uniquely balances SMB SMT compatibility, RoHS/halogen-free compliance, and 3.0 µs trr-making it optimal for automated, space-constrained, and environmentally regulated consumer and industrial power supplies.

FAQ
What is the maximum junction temperature for continuous operation of S1GB-13?
The S1GB-13 has an operating temperature range of –65°C to +150°C. For continuous 1.0 A DC operation, the terminal temperature must be maintained at ≤ +100°C per the derating curve; this corresponds to a maximum steady-state junction temperature of approximately +130°C when mounted on a 5 mm² copper pad (RθJT = 30 °C/W).
Can S1GB-13 replace S1G in an existing SMB footprint design?
Yes-S1GB-13 is the commercial-grade, tape-and-reel packaged variant of the S1G rectifier in SMB package. Both share identical electrical specs (VRRM = 400 V, IO = 1.0 A, trr = 1.8–3.0 µs) and mechanical dimensions. The "B" suffix denotes SMB package; "-13" indicates 3,000-piece tape-and-reel packaging per Diodes' ordering convention.
Is S1GB-13 suitable for use in a PFC boost diode position?
No-S1GB-13 is not optimized for PFC boost stages. Its 3.0 µs reverse recovery time is too slow for typical 65–100 kHz PFC operation, risking excessive switching loss and EMI. Use dedicated ultrafast or FRED diodes (e.g., Diodes Inc. PFH1010, trr < 75 ns) instead for boost rectification.
Does S1GB-13 require pre-baking before reflow soldering?
No-S1GB-13 is rated MSL Level 1 per J-STD-020, meaning it has unlimited floor life at ≤30°C/60% RH and requires no pre-bake prior to standard lead-free reflow (peak 260°C). This simplifies SMT line integration and eliminates moisture-related popcorning risk.
