Product details
Overview
S3MB-13-F from Diodes Incorporated is a 3.0A, 1000V glass passivated surface-mount rectifier diode in SMB package, featuring 1.15V forward voltage at 3.0A, 100A non-repetitive surge capability, and RoHS-compliant matte tin plating. It serves as a primary AC/DC input stage rectifier in offline power supplies for industrial control systems requiring high-voltage blocking and thermal robustness.
For engineers reviewing the S3MB-13-F datasheet, S3MB-13-F pinout, S3MB-13-F application, or S3MB-13-F equivalent, key selection criteria include peak repetitive reverse voltage (1000V), average forward current (3.0A @ TT=75°C), thermal resistance (10°C/W), junction temperature range (–65°C to +150°C), and SMB package compatibility with automated SMT assembly.
Technical Context
This device operates as a single-phase, half-wave silicon rectifier optimized for resistive or inductive loads at 60Hz line frequency. Its glass passivated die construction ensures stable reverse leakage (<250µA at 125°C) and reliable surge handling up to 100A for 8.3ms.
The SMB package provides defined thermal path (RθJT = 10°C/W with 5.0mm² copper pad) and polarity identification via cathode band. Capacitance is low (40pF at 1MHz, 4V reverse bias), minimizing switching noise in high-frequency rectification circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 1000 V - Blocks up to 1000V peak reverse voltage, suitable for 700V RMS mains-derived inputs. |
| IO | 3.0 A @ TT=75°C - Sustains continuous DC output current in compact SMB footprint with adequate heatsinking. |
| VFM | 1.15 V @ IF=3.0A - Low conduction loss enables >85% efficiency in 24V/48V SMPS front-end designs. |
| IFSM | 100 A - Withstands cold-start inrush surges common in capacitor-input filter stages. |
| RθJT | 10 °C/W - Enables predictable junction temperature rise when mounted on standard PCB copper pads. |
| IRM | 250 µA @ 125°C - Low high-temperature leakage preserves system reliability in enclosed industrial enclosures. |
| CT | 40 pF @ 1MHz - Minimizes EMI generation during commutation in high-frequency flyback converters. |

Applications
| Industrial Power Supply Input Stage | LED Driver Bulk Rectification |
|---|---|
Use Scenario: AC mains rectification in DIN-rail mounted 24V/48V industrial PSUs with wide ambient temperature range (–40°C to +85°C). IC Role / Device Role / Timing Role: Primary silicon rectifier converting 100–240VAC input to unregulated DC bus before PFC or buck conversion. Use Value: 1000V VRRM prevents breakdown during 1.5kV surge tests; 3.0A IO supports 75W output with margin. | Use Scenario: Off-line LED driver for street lighting operating continuously at elevated ambient temperatures. IC Role / Device Role / Timing Role: Bridgeless or single-diode rectifier in constant-current LED driver front-end. Use Value: Low 1.15V VFM reduces conduction loss and thermal stress on PCB; 150°C max TJ enables operation in sealed luminaires. |
| Uninterruptible Power System Charger | Motor Drive Auxiliary Power Supply |
Use Scenario: Battery charger input rectification in UPS units where reliability over 10-year service life is critical. IC Role / Device Role / Timing Role: High-voltage rectifier feeding bulk capacitor bank charged from utility or generator source. Use Value: <250µA IRM at 125°C ensures minimal self-discharge and standby power loss during battery float mode. | Use Scenario: Auxiliary 12V/24V supply powering gate drivers and logic in 3-phase inverter modules.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH3L06S | 600V VRRM, 3.0A IO, TO-277 package (lower thermal resistance: 7°C/W) | Lower voltage rating limits use to ≤400VAC systems; TO-277 requires different footprint and stencil design. | Select when lower forward drop (0.95V) and higher thermal performance outweigh voltage headroom needs. |
| ON Semi MUR3100CT | 1000V VRRM, dual common-cathode configuration, TO-220AC package | Through-hole mounting; higher thermal mass but incompatible with SMT-only production; includes internal dual-die layout. | Choose for legacy through-hole designs or where dual-diode topology simplifies bridge implementation. |
Compared with STTH3L06S and MUR3100CT, S3MB-13-F uniquely balances 1000V rating, SMB SMT compatibility, and industry-standard thermal resistance-making it optimal for new industrial power supply designs prioritizing manufacturability and safety margin.

FAQ
What is the maximum allowable junction temperature for S3MB-13-F?
The absolute maximum junction temperature is +150°C, with continuous operation rated from –65°C to +150°C. Derating begins above +75°C terminal temperature, where average forward current drops linearly to zero at +150°C per the published derating curve.
Is S3MB-13-F suitable for capacitance-input filter applications?
No-capacitance-input filters require 20% derating of the average forward current (to 2.4A) due to increased peak current stress. The datasheet explicitly states this derating condition for capacitive loads, which applies directly to S3MB-13-F.
Does S3MB-13-F have a specified reverse recovery time (trr)?
No-the S3A/B–S3M/B series are standard recovery rectifiers, not fast or ultrafast types. Reverse recovery time is not characterized or guaranteed in the datasheet; design assumptions should treat it as unspecified and avoid high-frequency switching (>10kHz) applications.
How is polarity identified on the S3MB-13-F SMB package?
Polarity is marked by a distinct cathode band on the top surface of the SMB package. The band aligns with the cathode terminal; the opposite end is the anode. This marking is visible under standard optical inspection and matches the mechanical drawing in AP02002.
