Product details
Overview
S1BB M4G from Taiwan Semiconductor is a 1 A, 100 V standard surface-mount silicon rectifier diode in DO-214AA (SMB) package, featuring glass-passivated junction, low forward voltage drop (max 1.1 V at 1 A), and 30 A surge capability - used in AC/DC front-end stages of compact SMPS and LED drivers.
For engineers reviewing the S1BB M4G datasheet, S1BB M4G pinout, S1BB M4G application, or S1BB M4G equivalent, key selection criteria include repetitive peak reverse voltage (100 V), thermal resistance (30 °C/W), moisture sensitivity level (J-STD-020 Level 1), RoHS/halogen-free compliance, and SMB footprint compatibility with automated placement.
Technical Context
This single-die standard rectifier operates as a unidirectional current path in non-synchronous buck, flyback, and bridge configurations. Its glass-passivated junction ensures stable reverse leakage (<5 µA at 25°C, <50 µA at 125°C) and robustness against humidity-induced degradation.
The device's 30 °C/W junction-to-lead thermal resistance enables reliable 1 A continuous conduction in SMB-mounted PCBs without forced airflow. Junction capacitance is specified at 12 pF (1 MHz, 4 V reverse bias), supporting moderate-frequency switching up to ~100 kHz in cost-sensitive power conversion.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Maximum repetitive reverse voltage the diode blocks without breakdown; defines usable input range in 85–265 VAC SMPS designs. |
| IF | 1 A - Continuous average forward current rating; supports output power up to ~12 W in 12 V secondary-side rectification. |
| IFSM | 30 A - Non-repetitive surge current handling for 8.3 ms half-sine; withstands inrush during cold-start or line transients. |
| VF (max) | 1.1 V @ 1 A, 25°C - Forward voltage drop directly impacts conduction loss; contributes ~1.1 W dissipation at full load. |
| RθJL | 30 °C/W - Thermal resistance from junction to lead; allows ~30°C temperature rise above PCB copper at 1 A DC in typical SMB layout. |
| IR (max) | 5 µA @ 25°C - Reverse leakage current; negligible power loss in high-impedance bias networks or hold-up circuits. |
| CJ | 12 pF @ 1 MHz, 4 V - Junction capacitance affects reverse recovery behavior and EMI generation in hard-switched topologies. |
Pinout & Package
Package: DO-214AA (SMB), surface-mount, cathode indicated by band. Matte tin-plated leads, UL 94V-0 molding compound, JESD201 Class 2 whisker resistant.

IC Role / Device Role / Timing Role: Discrete rectifying element in discrete bridge configuration; replaces integrated bridge for thermal isolation. Use Value: RθJL = 30 °C/W enables direct mounting to copper pour, reducing junction temperature rise by ~15°C vs. higher-Rθ alternatives. | Use Scenario: Bias winding rectification supplying VCC to PWM controller in 5–12 W wall adapters. IC Role / Device Role / Timing Role: Low-current auxiliary rectifier delivering ≤100 mA at 15–20 V; operates continuously at light load. Use Value: IR ≤ 5 µA at 25°C ensures minimal standby power draw - critical for meeting DOE Level VI and EU CoC Tier 2 requirements. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar standard rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor MUR110T3G | Ultrafast recovery (trr ≈ 75 ns vs. S1BB M4G's ~1.5 µs), VF = 0.92 V max, same 100 V VRRM and SMB package. | Preferred in PFC boost diodes or higher-frequency flybacks (>150 kHz); not needed for basic 65–100 kHz SMPS. | Select MUR110T3G only if trr-driven EMI or efficiency gain justifies cost premium over S1BB M4G. |
| Vishay VS-1EWH06-M3/5AT | Same 100 V VRRM, 1 A IF, SMB package, but VF = 1.05 V max and IR = 10 µA max at 25°C - slightly higher leakage. | Valid drop-in replacement where tighter VF tolerance is not required and 10 µA IR is acceptable in auxiliary rails. | VS-1EWH06-M3/5AT offers identical mechanical fit and comparable electrical envelope; verify IR impact in ultra-low-standby designs. |
Compared with MUR110T3G and VS-1EWH06-M3/5AT, the S1BB M4G delivers optimal balance of cost, thermal performance (30 °C/W), and leakage (5 µA), making it ideal for cost-sensitive, thermally constrained 65–100 kHz SMPS where ultrafast recovery is unnecessary.

FAQ
What is the maximum junction temperature rating for the S1BB M4G?
The S1BB M4G has a maximum junction temperature (TJ) rating of +150°C, with operational range from –55°C to +150°C. This allows reliable operation in enclosed power supplies with limited airflow, provided thermal design maintains junction temperature below this limit using its 30 °C/W RθJL and appropriate PCB copper area. The S1BB M4G's TJ rating matches industry-standard requirements for industrial-grade rectifiers.
Does the S1BB M4G have a defined reverse recovery time (trr)?
No, the S1BB M4G datasheet does not specify reverse recovery time (trr) because it is a standard (non-fast or ultrafast) rectifier. Its recovery behavior is characterized by relatively slow turn-off - typically in the microsecond range (~1.5 µs). For applications requiring fast switching (e.g., >100 kHz with low EMI), the S1BB M4G is not recommended; instead, consider ultrafast alternatives like MUR110T3G. The S1BB M4G is optimized for fundamental-frequency rectification in 65–100 kHz SMPS.
Is the S1BB M4G suitable for use in automotive applications?
The S1BB M4G is not qualified to AEC-Q101 or automotive-grade reliability standards. While its electrical specs (100 V VRRM, 150°C TJ) meet some automotive voltage/temperature thresholds, Taiwan Semiconductor does not list it in automotive-qualified product families. It is intended for industrial, commercial, and consumer power supplies. For automotive use, select AEC-Q101-certified rectifiers such as ON Semiconductor's MUR110E or Vishay's ES1BHM3/86A. The S1BB M4G remains appropriate for non-automotive applications only.
What does the "M4G" suffix indicate in S1BB M4G?
The "M4G" suffix in S1BB M4G denotes Taiwan Semiconductor's internal packaging and environmental code: "M" indicates DO-214AA (SMB) package, "4" specifies green (halogen-free) molding compound per IEC 61249-2-21, and "G" confirms RoHS compliance. This matches the ordering code structure in the datasheet where "S1xB" maps to voltage grade (B = 100 V), and "M4G" identifies the eco-friendly SMB variant. No functional difference exists between S1BB M4G and S1BB variants with different suffixes beyond environmental and packaging attributes.
Can the S1BB M4G replace a 1N4007 in a new design?
The S1BB M4G is not a direct replacement for the through-hole 1N4007 due to package (SMB vs. DO-41), thermal profile (30 °C/W vs. ~65 °C/W), and surge rating (30 A vs. 30 A but different waveform definition). While both are 1 A, 1000 V-rated general-purpose rectifiers, the S1BB M4G is rated for 100 V VRRM - not 1000 V. Using S1BB M4G in place of 1N4007 risks reverse breakdown. For surface-mount equivalents to 1N4007, consider S1M (1000 V) in the same S1x series. Always verify VRRM, package, and surge specifications before substitution. The S1BB M4G is correctly applied only where 100 V blocking is sufficient.
