Product details

Overview

S1BB R5G from Taiwan Semiconductor is a 1 A, 100 V standard surface-mount silicon rectifier diode in DO-214AA (SMB) package, featuring glass-passivated junction, 1.1 V max forward voltage at 1 A, 30 A surge capability, and 5 µA max reverse leakage at 25°C - used in AC/DC input stages of compact SMPS and LED drivers.

For engineers reviewing the S1BB R5G datasheet, S1BB R5G pinout, S1BB R5G application, or S1BB R5G 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 tape-and-reel packaging for automated assembly.

Technical Context

The S1BB R5G is a single-die, unidirectional standard recovery rectifier optimized for general-purpose switching power conversion. Its glass-passivated junction ensures stable reverse characteristics across temperature, while the DO-214AA (SMB) package supports high-density PCB layouts and reflow soldering per J-STD-002.

It operates with a maximum junction temperature of 150°C and exhibits typical junction capacitance of 12 pF at 1 MHz and 4 V reverse bias. Reverse leakage remains ≤5 µA at 25°C and ≤50 µA at 125°C under rated V_R, enabling reliable performance in thermally constrained adapters and lighting ballasts.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	100 V - Maximum repetitive reverse voltage the device blocks without breakdown; defines usable input voltage range in bridge or single-diode rectification.
I_F	1 A continuous - Rated average forward current at case temperature ≤75°C; determines steady-state power handling in linear or low-frequency switching topologies.
I_FSM	30 A (8.3 ms half-sine) - Peak non-repetitive surge current capacity; enables robustness against line transients and inrush in offline converters.
V_F	≤1.1 V @ 1 A, 25°C - Forward voltage drop directly impacts conduction loss and thermal design; critical for efficiency in 5–24 V output SMPS.
R_θJL	30 °C/W - Junction-to-lead thermal resistance; allows direct estimation of junction temperature rise above lead temperature in PCB-mounted applications.
I_R	≤5 µA @ 100 V, 25°C - Low reverse leakage preserves efficiency in high-impedance hold-up or sensing circuits and reduces standby power loss.
C_J	12 pF @ 1 MHz, 4 V - Junction capacitance affects high-frequency switching noise and EMI filter design; relevant for snubberless flyback or PFC pre-regulator stages.

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 M100SFT1G	Same DO-214AA package, 100 V V_RRM, but 1.05 V typ V_F (vs. 1.1 V max for S1BB R5G); 25 A I_FSM (vs. 30 A)	Slightly lower conduction loss at light loads; reduced surge margin may require derating in high-transient environments	Prefer when optimizing for ultra-low V_F at <0.5 A, with verified surge immunity in final system test
Vishay VS-1EWH01-M3/5AT	DO-214AC (SMA) package (smaller footprint), same 100 V rating, 1.1 V max V_F, but only 20 A I_FSM and 25°C/W R_θJL	Higher power density but lower thermal mass; less suitable for sustained 1 A operation near 75°C ambient	Select when board space is constrained and thermal management includes forced airflow or copper pour

Compared with M100SFT1G and VS-1EWH01-M3/5AT, the S1BB R5G delivers superior surge robustness (30 A) and thermal resistance (30 °C/W) in the widely supported DO-214AA footprint - making it optimal for cost-sensitive, thermally demanding adapter and lighting designs where reliability under transient stress is prioritized.

FAQ

What is the maximum junction temperature rating for the S1BB R5G?

The S1BB R5G has a maximum junction temperature (T_JMAX) of +150°C, as specified in its absolute maximum ratings table. This rating applies under continuous operation with proper thermal management - including adequate PCB copper area and ambient conditions below 75°C. Exceeding this limit risks permanent degradation of the glass-passivated junction. The S1BB R5G datasheet confirms this value across all S1x family variants.

Is the S1BB R5G suitable for use in RoHS-compliant and halogen-free assemblies?

Yes, the S1BB R5G is both RoHS compliant and halogen-free per IEC 61249-2-21. Taiwan Semiconductor explicitly states this in the FEATURES section of the official datasheet (Version I2102). The device uses matte tin-plated leads and UL 94V-0 molding compound, meeting environmental requirements for consumer, industrial, and medical-grade end products - provided the full BOM adheres to applicable exemptions and declarations.

What does the 'R5G' suffix indicate in the S1BB R5G part number?

The 'R5G' suffix in S1BB R5G denotes Taiwan Semiconductor's internal packaging and marking code: 'R' indicates tape-and-reel packaging (3,000 units per reel), '5' specifies green molding compound, and 'G' identifies the manufacturing facility. This coding aligns with TSC's ordering information table and is consistent across the S1AB–S1MB family - confirming the S1BB R5G is supplied in DO-214AA (SMB) format with J-STD-020 Level 1 handling.

How does the forward voltage of the S1BB R5G compare to similar 1 A rectifiers?

The S1BB R5G has a maximum forward voltage (V_F) of 1.1 V at 1 A and 25°C, matching industry-standard values for DO-214AA rectifiers. It is slightly higher than M100SFT1G (1.05 V typ) but lower than older-generation devices like 1N4007 (1.2 V min). This V_F reflects a balance of low-loss conduction and rugged junction design - confirmed in the ELECTRICAL SPECIFICATIONS table of the S1BB R5G datasheet.

Can the S1BB R5G replace the S1AB or S1DB in an existing design?

No - the S1BB R5G is not a drop-in replacement for S1AB (50 V) or S1DB (200 V), as each variant has distinct V_RRM ratings. Substituting S1BB R5G (100 V) for S1DB (200 V) risks reverse breakdown under normal operating voltage. The S1BB R5G is only functionally interchangeable with other 100 V-rated members of the S1x family, such as S1BB without suffix or S1BB R5G equivalents from authorized distributors - always verify voltage margin per application.
