Product details

Overview

S8MC-13 from Diodes Incorporated is an 8.0A surface-mount glass passivated rectifier in SMC package, rated for 1000V peak repetitive reverse voltage (V_RRM), 0.985V forward voltage at 8.0A, and 10μA reverse leakage at 25°C, used in AC/DC front-end rectification for industrial power supplies.

For engineers reviewing the S8MC-13 datasheet, S8MC-13 pinout, S8MC-13 application, or S8MC-13 equivalent, key selection criteria include V_RRM = 1000V, I_O = 8.0A, surge rating I_FSM = 200A (8.3ms), thermal resistance R_θJT = 10°C/W, and SMC package compatibility with automated assembly.

Technical Context

This device is a single-phase, silicon planar junction rectifier with guard ring structure for transient protection and enhanced surge robustness. It operates under resistive or inductive loads at 60Hz, with derating required for capacitive loads (−20% current).

Electrical behavior is defined by low forward conduction loss (V_FM = 0.985V @ 8A), fast recovery time (T_RR = 2700ns), and stable reverse blocking up to 1000V, supported by glass passivation for moisture and contamination resistance.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	1000 V - Maximum non-repetitive reverse voltage the device blocks without breakdown
I_O	8.0 A - Average forward rectified current at T_T = +75°C, defining continuous power handling
V_FM	0.985 V @ 8.0A - Forward voltage drop determining conduction loss and thermal rise in high-current paths
I_FSM	200 A @ 8.3ms - Non-repetitive surge capability enabling tolerance of line transients and inrush events
R_θJT	10 °C/W - Junction-to-terminal thermal resistance, critical for heatsink design and power dissipation management
T_RR	2700 ns - Reverse recovery time affecting switching losses and EMI in higher-frequency rectifier topologies
I_R	10 μA @ 25°C - Reverse leakage current influencing standby power and high-impedance circuit integrity

Pinout & Package

Package: SMC (DO-214AB), molded plastic case with UL 94V-0 flammability rating, matte tin-plated terminals, cathode band polarity marking, and 0.21g mass.

Pin/Terminal	Circuit Role	Design Meaning

Applications

Industrial Power Supply Rectification

AC Motor Drive Input Stage

Use Scenario: Full-wave bridge rectification in 3-phase or single-phase industrial SMPS with 400–690V AC input.

IC Role / Device Role / Timing Role: Discrete rectifier diode in bridge configuration, converting AC line to unregulated DC bus.

Use Value: 1000V V_RRM withstands reflected transients; 8A I_O sustains continuous load; 200A I_FSM absorbs motor inrush.

Use Scenario: Input rectification for variable frequency drives powering HVAC compressors or pumps.

IC Role / Device Role / Timing Role: High-current, high-voltage rectifier in passive front-end stage before DC link capacitor.

Use Value: Low V_FM reduces conduction loss and heat generation; glass passivation ensures reliability in dusty, humid factory environments.

Uninterruptible Power Supply (UPS) Charger

Welding Equipment Power Stage

Use Scenario: Battery charger rectifier in online UPS systems with dual AC input paths and high surge demands.

IC Role / Device Role / Timing Role: Primary AC-to-DC conversion element feeding battery charging circuitry and inverter DC bus.

Use Value: 2700ns T_RR limits switching noise; 10μA I_R minimizes standby leakage across large DC-link capacitors.

Use Scenario: Main rectifier in arc welding power supplies requiring high peak current delivery and thermal resilience.

IC Role / Device Role / Timing Role: Heavy-duty rectifier in transformer-secondary side, directly feeding thyristor or IGBT inverter stage.

Use Value: 10°C/W R_θJT enables efficient heat transfer to chassis-mounted heatsinks; 450A I_FSM (1ms) handles short-circuit weld initiation pulses.

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-voltage, high-current rectifier applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STTH8R06D	V_RRM = 600V, T_RR = 65ns, V_F = 1.7V @ 8A	Lower voltage rating; faster recovery but higher conduction loss	Select only if system V_RRM requirement ≤600V and EMI-sensitive; avoid for 1000V line applications
VS-8EWH06FN-M3	V_RRM = 600V, I_O = 8A, V_F = 1.15V @ 8A, SMC package	Same package and current rating, but insufficient V_RRM margin for 1000V use cases	Acceptable only in 400–480V AC systems with adequate derating; not a drop-in replacement for S8MC-13

Compared with STTH8R06D and VS-8EWH06FN-M3, the S8MC-13 uniquely delivers 1000V blocking with 0.985V forward drop in SMC-enabling compact, high-efficiency rectification where both voltage margin and thermal performance are critical.

FAQ

What is the maximum operating temperature for the S8MC-13?

The S8MC-13 has an operating junction temperature range of −65°C to +150°C. Its thermal resistance (R_θJT = 10°C/W) allows safe operation at 8A average current when mounted on a sufficient copper heatsink area, with terminal temperature limited to +75°C per datasheet derating curves.

Is the S8MC-13 compatible with lead-free reflow soldering?

Yes-the S8MC-13 features matte tin-plated terminals qualified for lead-free reflow soldering per MIL-STD-202, Method 208. Its Level 1 moisture sensitivity eliminates pre-bake requirements, supporting standard SMT assembly processes without special handling.

Does the S8MC-13 have a specified reverse recovery time?

Yes-its typical reverse recovery time (T_RR) is 2700 ns, measured under IF = 0.5A, IR = 1.0A, and IRR = 0.25A conditions. This value reflects its soft-recovery characteristic suitable for line-frequency rectification, not high-frequency switching.

Can the S8MC-13 be used in a full-wave bridge configuration?

Yes-it is commonly deployed as one leg in discrete full-wave bridge rectifiers. Four S8MC-13 devices can form a 1000V, 8A-rated bridge; polarity is indicated by cathode band, and thermal layout must ensure uniform heatsinking across all four devices.
