Product details

Overview

S5G M6G from Taiwan Semiconductor is a 5 A, 400 V surface-mount silicon rectifier diode in DO-214AB (SMC) package, featuring glass-passivated junction, low forward voltage drop (max 1.15 V at 5 A), and high surge capability (100 A IFSM). It serves as a primary AC/DC conversion device in compact offline power supplies.

For engineers reviewing the S5G M6G datasheet, S5G M6G pinout, S5G M6G application, or S5G M6G equivalent, key selection criteria include repetitive peak reverse voltage (400 V), thermal resistance (R_θJL = 13 °C/W), junction capacitance (60 pF), reverse recovery time (1500 ns), and moisture sensitivity level (MSL 1).

Technical Context

The S5G M6G is a single-die, standard recovery rectifier optimized for switching-mode power supplies operating up to 100 kHz. Its 1500 ns reverse recovery time and 60 pF junction capacitance reflect trade-offs between switching loss and EMI control in mid-frequency converters.

Thermally, it delivers 5 A average forward current with junction-to-lead resistance of 13 °C/W and junction-to-ambient resistance of 47 °C/W under natural convection. Polarity is marked by cathode band on the DO-214AB body.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	400 V - Maximum non-repetitive reverse voltage the device blocks without breakdown; defines maximum input AC peak voltage in bridge or single-diode configurations.
I_F	5 A - Continuous average forward current rating at T_L = 75 °C; determines heatsink-free operation in low-power adapters.
I_FSM	100 A - Peak non-repetitive surge current (8.3 ms half-sine); supports inrush current handling during cold-start in SMPS.
V_F	≤1.15 V @ 5 A, 25 °C - Forward voltage drop directly impacts conduction loss and thermal rise in high-duty-cycle applications.
t_rr	1500 ns - Reverse recovery time affects switching loss and EMI generation when used in discontinuous conduction mode (DCM) flyback designs.
R_θJL	13 °C/W - Junction-to-lead thermal resistance enables direct PCB copper pour thermal coupling without additional heatsinks in space-constrained layouts.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STTH5L06 from STMicroelectronics	600 V V_RRM, 5 A I_F, 1200 ns t_rr, TO-220AC package	Higher voltage rating but through-hole; requires PCB mounting change and larger thermal pad	Select when higher reverse margin or legacy through-hole assembly is required.

FAQ

What is the maximum junction temperature rating for the S5G M6G?

The S5G M6G has a maximum junction temperature (T_JMAX) of +150 °C, allowing operation in thermally demanding environments such as enclosed LED drivers or motor drive auxiliary supplies. This rating is validated per JEDEC JESD22-A104 and applies across the full -55 °C to +150 °C storage range. The S5G M6G maintains electrical performance within specification up to this limit when thermal design respects R_θJL = 13 °C/W.

Does the S5G M6G meet RoHS and halogen-free requirements?

Yes, the S5G M6G is RoHS compliant and halogen-free per IEC 61249-2-21. Taiwan Semiconductor confirms that all materials-including molding compound, lead frame, and plating-meet these environmental standards. The device carries no restricted substances above threshold limits and is suitable for export to EU, Japan, and other regulated markets. This compliance is documented in TSC's official material declarations for the S5A–S5M family.

What is the reverse recovery time (t_rr) of the S5G M6G and how is it measured?

The S5G M6G has a typical reverse recovery time (t_rr) of 1500 ns, measured under conditions of I_F = 0.5 A, I_R = 1.0 A, and I_rr = 0.25 A per JEDEC JESD28-C. This value reflects its standard recovery behavior-suitable for <100 kHz SMPS topologies but not recommended for high-frequency ZVS or GaN-based designs where ultrafast recovery (<100 ns) is required. The S5G M6G datasheet specifies no minimum t_rr; 1500 ns is the typical value.

Can the S5G M6G be used in place of the S5J (600 V) in a 400 V design?

Yes-the S5G M6G is rated for 400 V V_RRM, making it functionally appropriate for circuits where peak reverse voltage does not exceed that level. Substituting S5G M6G for S5J in a 400 V design reduces cost and maintains identical DO-214AB footprint and thermal performance. However, the S5G M6G must not replace S5J in systems exposed to transient overvoltage exceeding 400 V, as it lacks the 600 V safety margin. Always validate with worst-case transient analysis before substitution.

What is the marking code and polarity identification method for the S5G M6G?

The S5G M6G is marked with "S5G" on the device body, followed by green compound indicator "G", date code "YW", and factory code "F". Polarity is unambiguously indicated by a cathode band located at the cathode end of the DO-214AB package. This band aligns with the cathode terminal in the standard SMC outline and is verified optically during automated placement. No alternate marking schemes or dual-band configurations apply to the S5G M6G.
