Product details

Overview

S5B M6G from Taiwan Semiconductor is a 5A, 100V surface-mount general-purpose rectifier diode in DO-214AB (SMC) package, featuring glass-passivated junction, low forward voltage drop (max 1.15 V at 5 A), high surge current capability (100 A), and RoHS/halogen-free compliance. It serves as the main AC-to-DC conversion element in compact off-line SMPS and LED driver secondary-side rectification.

For engineers reviewing the S5B M6G datasheet, S5B M6G pinout, S5B M6G application, or S5B M6G equivalent, key selection criteria include repetitive peak reverse voltage (100 V), forward current rating (5 A), thermal resistance (R_θJL = 13 °C/W), reverse recovery time (1500 ns), and moisture sensitivity level (MSL 1).

Technical Context

The S5B M6G is a single-die, standard recovery silicon rectifier optimized for cost-sensitive, medium-frequency switching applications up to ~100 kHz. Its 1500 ns reverse recovery time and 60 pF junction capacitance reflect trade-offs between switching loss and conduction efficiency in flyback and forward converter outputs.

Thermally, it delivers 5 A average forward current with junction temperature limited to 150 °C, supported by R_θJL = 13 °C/W to lead and R_θJA = 47 °C/W to ambient - requiring minimal copper area for PCB heat spreading in typical SMC footprint layouts.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	100 V - Maximum non-repetitive reverse voltage the device blocks without breakdown; defines minimum input/output isolation margin in 12–24 V output SMPS designs.
I_F	5 A - Continuous average forward current at T_A = 25 °C; derates linearly above 25 °C per forward current derating curve.
V_F (max)	1.15 V @ 5 A, 25 °C - Directly impacts conduction loss (P_cond ≈ I_F × V_F) and thermal load in high-duty-cycle operation.
I_FSM	100 A @ 8.3 ms - Withstands short-duration line surges or startup inrush without failure; critical for adapter reliability under cold-start conditions.
t_rr	1500 ns - Limits usable switching frequency; suitable for ≤100 kHz topologies but not recommended for >200 kHz synchronous rectification.
R_θJL	13 °C/W - Enables efficient heat transfer from die to PCB copper via leads; supports thermal design with minimal external heatsinking.

Equivalent & Alternatives

The following parts are listed as comparable options for similar rectifier applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STTH5L06D (STMicroelectronics)	600 V V_RRM, 5 A, t_rr = 75 ns, TO-277 package	Designed for higher-voltage, faster-switching PFC stages; not drop-in due to different package and voltage rating.	Select only if system requires >100 V blocking or <100 ns recovery; requires PCB redesign.
ES5B (ON Semiconductor)	100 V V_RRM, 5 A, t_rr = 1500 ns, DO-214AB package, VF = 1.15 V max	Functionally identical voltage/current/recovery specs and same DO-214AB footprint; minor differences in leakage (IR = 5 µA vs. 10 µA) and thermal resistance (R_θJL = 12.5 °C/W).	Valid alternative with same board layout; verify IR spec tolerance in high-temperature designs.

Compared with STTH5L06D, the S5B M6G offers lower cost and sufficient performance for 100 V-class outputs but lacks speed for high-frequency PFC. Compared with ES5B, it matches core electrical behavior and mechanical fit while differing slightly in leakage and thermal metrics - making ES5B the closest functional substitute.

FAQ

What is the maximum repetitive peak reverse voltage (V_RRM) of the S5B M6G?

The S5B M6G has a V_RRM of 100 V, meaning it reliably blocks up to 100 V of reverse voltage in repetitive operation. This rating is confirmed in the Absolute Maximum Ratings table on page 2 of the official Taiwan Semiconductor datasheet (Version F2102). Exceeding this voltage risks avalanche breakdown and permanent damage to the S5B M6G.

Does the S5B M6G have a halogen-free construction?

Yes, the S5B M6G is halogen-free in accordance with IEC 61249-2-21, as explicitly stated in the FEATURES section of the Taiwan Semiconductor datasheet. This applies to both the molding compound and internal materials, supporting compliance with environmental directives such as China RoHS and JEITA EG-02.

What is the reverse recovery time (t_rr) of the S5B M6G, and how does it affect circuit design?

The S5B M6G has a reverse recovery time of 1500 ns under specified test conditions (I_F = 0.5 A, I_R = 1.0 A, I_rr = 0.25 A). This relatively long t_rr limits its use to switching frequencies below ~100 kHz; using the S5B M6G in higher-frequency converters increases switching losses and EMI, potentially requiring snubber networks or derating.

Is the S5B M6G suitable for reflow soldering without pre-baking?

Yes, the S5B M6G is rated MSL Level 1 per J-STD-020, meaning it can be placed directly onto PCBs and subjected to standard lead-free reflow profiles without prior baking. This eliminates moisture-related popcorning risk and simplifies SMT line integration - a verified specification documented in the MECHANICAL DATA section of the datasheet.

What package type does the S5B M6G use, and what are its key mechanical attributes?

The S5B M6G uses the DO-214AB (SMC) surface-mount package, with matte tin-plated leads compliant with J-STD-002, UL 94V-0 flammability-rated molding compound, and cathode polarity indicated by a visible band. Its weight is approximately 0.210 g, and the suggested pad layout is provided in the PACKAGE OUTLINE DIMENSIONS section of the datasheet.
