Product details
Overview
S5MC-13 from Diodes Incorporated is a 1000 V PIV, 5.0 A average forward current glass passivated surface-mount rectifier in SMC package, featuring 1.15 V max forward voltage at 5.0 A and 100 A non-repetitive surge capability; used in AC/DC front-end rectification for industrial power supplies and LED drivers.
For engineers reviewing the S5MC-13 datasheet, S5MC-13 pinout, S5MC-13 application, or S5MC-13 equivalent, key selection criteria include peak reverse voltage rating, thermal resistance (10 °C/W), surge robustness (100 A @ 8.3 ms), and RoHS-compliant lead-free plating for automated assembly.
Technical Context
This device operates as a single-phase, half-wave silicon rectifier optimized for high-voltage, medium-current DC output generation. Its glass passivated die construction ensures stable reverse leakage (<10 µA @ 25°C) and enhanced reliability under thermal cycling.
The SMC package enables efficient heat dissipation with 10 °C/W junction-to-terminal thermal resistance when mounted on 5.0 mm² copper pads. Derating curves confirm sustained 5.0 A operation up to +75°C terminal temperature and full surge rating only below 125°C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Reverse Voltage | 1000 V - supports input rectification from 700 V RMS AC lines or high-voltage DC link clamping |
| Avg Forward Current | 5.0 A @ TT = +75°C - defines continuous conduction capability in thermally constrained PCB layouts |
| Max Forward Voltage | 1.15 V @ IF = 5.0 A - determines conduction loss (5.75 W) and thermal load in high-duty-cycle applications |
| Surge Current | 100 A @ 8.3 ms - withstands inrush into capacitive loads without degradation |
| Thermal Resistance | 10 °C/W (Junction-to-Terminal) - enables direct thermal path to copper pour for passive cooling |
| Reverse Leakage | 10 µA @ 25°C, 250 µA @ 125°C - impacts standby power and high-impedance bias network stability |
| Capacitance | 40 pF @ 4 V, 1 MHz - limits high-frequency noise coupling in switching converter inputs |
Pinout & Package
Package: SMC (DO-214AB), molded plastic case with UL 94V-0 flammability rating, cathode indicated by band or notch, matte tin-plated terminals solderable per MIL-STD-202 Method 208.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

Applications
| Industrial AC/DC Power Supplies | LED Driver Input Rectification |
|---|---|
Use Scenario: Rectifying 230 VAC mains input in enclosed 50–100 W industrial power supplies operating continuously at +60°C ambient. IC Role / Device Role / Timing Role: Primary-side unidirectional current switch converting AC line to pulsating DC before bulk capacitance. Use Value: 1000 V PIV margin prevents breakdown during line surges; 10 °C/W RθJT allows thermal management without heatsink. | Use Scenario: Front-end rectification in outdoor-rated LED streetlight drivers exposed to wide temperature swings and lightning-induced transients. IC Role / Device Role / Timing Role: High-voltage AC input stage delivering stable DC bus to constant-current LED controller ICs. Use Value: 100 A surge rating absorbs induced line transients; glass passivation resists humidity-driven leakage drift. |
| Switched-Mode Power Supply Inputs | DC Link Protection in Motor Drives |
Use Scenario: Input rectifier in 36 V/5 A offline SMPS for factory automation controllers with tight board space constraints. IC Role / Device Role / Timing Role: Half-wave rectifier feeding active PFC stage; must operate reliably at 50 kHz ripple frequency. Use Value: 40 pF junction capacitance minimizes high-frequency EMI coupling into control circuitry. | Use Scenario: Clamping diode across IGBT collector-emitter in 400 V DC bus of HVAC inverter drives. IC Role / Device Role / Timing Role: Freewheeling path for inductive motor current during IGBT turn-off. Use Value: Low 1.15 V forward drop reduces conduction loss during regeneration; 200 A 1 ms surge handles worst-case flyback energy. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH5L06S | 600 V PIV, 5 A, TO-277 package, 1.15 V VF - lower voltage rating, higher RθJA | Not suitable for 1000 V systems; requires larger thermal pad due to TO-277 mounting | Select only if system peak reverse stress remains ≤600 V and board layout permits TO-277 footprint |
| ON Semiconductor MUR5100CT | 1000 V PIV, dual common-cathode configuration, TO-220AC package, 1.75 V VF - higher VF, discrete leads | Requires through-hole assembly; higher conduction loss increases thermal demand in compact designs | Prefer for legacy through-hole builds where dual-diode topology simplifies bridge implementation |
Compared with STTH5L06S and MUR5100CT, S5MC-13 delivers superior voltage margin and surface-mount efficiency, enabling smaller footprints and lower conduction loss in modern high-density power supplies-without sacrificing surge immunity or environmental compliance.

FAQ
What is the maximum allowable junction temperature for continuous operation?
The S5MC-13 has an operating junction temperature range of –65°C to +150°C. For continuous 5.0 A conduction, the terminal temperature must not exceed +75°C per the derating curve. At higher ambient temperatures, current must be reduced linearly to maintain TJ ≤ 150°C using RθJT = 10 °C/W and measured thermal path conditions.
Is S5MC-13 suitable for use in a full-wave bridge configuration?
Yes - S5MC-13 is a single diode rated for 1000 V PIV and 5.0 A average current, making it appropriate for building discrete full-wave bridges. Four units can form a standard bridge rectifier; however, ensure matched thermal mounting and identical trace lengths to avoid current imbalance and localized overheating.
Does the S5MC-13 require snubber circuits in typical 50/60 Hz rectification?
No snubber is required for standard resistive or inductive loads at 50/60 Hz. However, in high-dI/dt switching applications (e.g., PFC pre-regulators), a small RC snubber across the diode may reduce voltage overshoot caused by stray inductance - especially when paired with fast-recovery downstream devices.
How does the 100 A surge rating relate to real-world lightning or capacitor inrush events?
The 100 A rating is defined per IEC 61000-4-5 for 8.3 ms half-sine surges - matching typical lightning-induced transients on AC mains. It also covers cold-start inrush into 1000 µF bulk capacitors charged from 230 VAC, where peak current exceeds 60 A. The glass passivated die ensures no parameter shift after repeated surges within spec.
