Product details
Overview
S3BBHM4G from Taiwan Semiconductor is a 3A, 100V standard surface-mount silicon rectifier diode in DO-214AA (SMB) package, featuring glass-passivated junction, low forward voltage drop (≤1.15 V at 3 A), and high surge capability (80 A IFSM). It serves as the primary AC-to-DC conversion element in compact off-line power supplies.
For engineers reviewing the S3BBHM4G datasheet, S3BBHM4G pinout, S3BBHM4G application, or S3BBHM4G equivalent, key selection criteria include repetitive peak reverse voltage (100 V), thermal resistance (10 °C/W), junction capacitance (40 pF), reverse recovery time (1500 ns), and moisture sensitivity level (J-STD-020 Level 1).
Technical Context
This device is a single-die, unidirectional, standard recovery rectifier optimized for cost-sensitive, medium-frequency switching applications up to ~100 kHz. Its 150 °C maximum junction temperature and 10 °C/W junction-to-lead thermal resistance support conduction-limited operation in thermally constrained layouts.
The 1500 ns reverse recovery time and 40 pF junction capacitance reflect its standard recovery architecture-suitable for flyback and forward converters where soft-switching or zero-voltage transition is not required, but unsuitable for high-frequency synchronous rectification or PFC stages demanding ultrafast recovery.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Maximum repetitive reverse voltage before breakdown; sets minimum input rectification rating for 70 V RMS AC inputs. |
| IF | 3 A - Continuous average forward current at TA = 75 °C; defines steady-state power handling in conduction mode. |
| IFSM | 80 A - Non-repetitive surge current (8.3 ms half-sine); supports inrush tolerance in SMPS input stages. |
| VF | ≤1.15 V @ 3 A, 25 °C - Forward voltage drop directly impacts conduction loss and thermal design margin. |
| trr | 1500 ns - Reverse recovery time determines switching loss and EMI generation in hard-switched topologies. |
| RθJL | 10 °C/W - Junction-to-lead thermal resistance enables direct PCB copper pour thermal coupling without heatsink. |
| CJ | 40 pF @ 1 MHz, 4 V - Junction capacitance affects high-frequency noise coupling and snubber sizing. |
Pinout & Package
Package: DO-214AA (SMB), surface-mount, single-anode/single-cathode configuration. Cathode indicated by molded band on body.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Lead 1) | Forward current entry point | Connected to AC input or transformer secondary; must withstand full surge current path. |
| Cathode (Lead 2) | Forward current exit / reverse blocking terminal | Connected to bulk capacitor or DC bus; polarity marking critical for correct orientation on PCB. |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated junction | Enables stable long-term reliability under humidity and thermal cycling; eliminates need for conformal coating in industrial environments. |
| Moisture sensitivity level 1 | Allows unlimited floor life before reflow; eliminates baking requirement and simplifies SMT line integration. |
| Matte tin-plated leads | Ensures robust solderability per J-STD-002; compatible with lead-free and SnPb reflow profiles without dewetting. |
| UL 94V-0 molding compound | Meets flammability safety requirements for Class II power supplies and lighting enclosures. |
Applications
| AC-DC Adapter Input Stage | LED Driver Secondary Rectification |
|---|---|
Use Scenario: Converts 100–240 VAC mains to DC bus in compact wall adapters rated ≤30 W. IC Role / Device Role / Timing Role: Primary bridge or single-phase rectifier delivering filtered DC to PWM controller IC. Use Value: 100 V VRRM safely handles 1.4× peak line voltage (170 V) with margin; 3 A IF supports typical adapter output currents. | Use Scenario: Rectifies high-frequency transformer output in isolated LED drivers for commercial lighting. IC Role / Device Role / Timing Role: Output-side freewheeling/rectifying diode synchronized with flyback transformer reset. Use Value: 1500 ns trr aligns with typical 65–100 kHz flyback operating frequencies; low VF minimizes heat in enclosed fixtures. |
| Industrial DC Power Module Input | USB-C PD Auxiliary Supply Rectifier |
Use Scenario: Front-end rectification in DIN-rail mounted 24 V DC power modules accepting 85–305 VAC input. IC Role / Device Role / Timing Role: Part of discrete bridge or single-diode stage feeding bulk capacitor and active PFC front-end. Use Value: 80 A IFSM withstands cold-start surges; 150 °C TJ max enables operation in high-ambient industrial cabinets. | Use Scenario: Secondary-side rectification in auxiliary 5 V/3.3 V bias supplies within USB-C PD controllers. IC Role / Device Role / Timing Role: Low-cost, space-efficient rectifier for low-power auxiliary rails powering PD protocol ICs and gate drivers. Use Value: DO-214AA (SMB) footprint fits tight layout constraints; halogen-free and RoHS compliance meets end-equipment regulatory requirements. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar standard rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH3L06S | 600 V VRRM, 3 A IF, 75 ns trr, TO-277 package | Ultrafast recovery enables higher-frequency operation; higher voltage rating suits universal-input designs | Choose when designing for >200 kHz switching or requiring ≥400 V reverse blocking |
| SB3100 | 100 V VRRM, 3 A IF, 35 ns trr, DO-214AA (SMB) package | Fast recovery reduces switching loss and EMI; same footprint enables drop-in evaluation | Choose when upgrading from standard to fast recovery without PCB redesign |
Compared with STTH3L06S and SB3100, the S3BBHM4G offers lower cost and proven thermal stability at 100 V/3 A, but trades off recovery speed-making it optimal for cost-driven, <100 kHz SMPS where EMI filtering is less critical.

FAQ
What is the maximum junction temperature rating for the S3BBHM4G?
The S3BBHM4G has a maximum junction temperature (TJ) of +150 °C, enabling reliable operation in enclosed power supplies and industrial environments where ambient temperatures exceed 85 °C. This rating is validated per JEDEC test conditions and supports derating curves shown in Figure 1 of the official TSC datasheet for S3BBHM4G.
Is the S3BBHM4G RoHS and halogen-free compliant?
Yes, the S3BBHM4G is RoHS compliant and halogen-free per IEC 61249-2-21. The device uses matte tin-plated leads and UL 94V-0 molding compound, satisfying environmental requirements for CE-marked lighting, adapters, and industrial equipment. Compliance documentation is available upon request for S3BBHM4G.
What does the 'HM4G' suffix in S3BBHM4G indicate?
The 'HM4G' suffix in S3BBHM4G denotes Taiwan Semiconductor's internal packaging and environmental coding: 'H' = halogen-free, 'M' = tape-and-reel packaging (3,000 units per reel), '4' = date code year (2024), and 'G' = green compound. This matches TSC's official ordering nomenclature for the S3AB–S3MB family, confirming S3BBHM4G as a 100 V variant in SMB package.
Can the S3BBHM4G replace a 1N4007 in a new design?
The S3BBHM4G is not a direct replacement for the 1N4007 due to differing packages (DO-214AA vs. DO-41) and electrical profiles: S3BBHM4G offers higher current (3 A vs. 1 A), lower VF (~1.15 V vs. ~1.7 V), but lower VRRM (100 V vs. 1000 V). Use S3BBHM4G only where 100 V blocking suffices and SMB footprint is acceptable-never as blind substitution in legacy 1N4007 designs.
What is the reverse leakage current specification for S3BBHM4G at elevated temperature?
At TJ = 125 °C and rated VR, the S3BBHM4G exhibits a maximum reverse leakage current (IR) of 250 µA, per TSC's Electrical Specifications table. This value is critical for standby power budgeting in energy-efficient adapters and must be verified under actual board-level thermal conditions, as ambient heating can elevate junction temperature beyond ambient readings.
