Product details
Overview
S15MCHM6G from Taiwan Semiconductor is a 15A, 1000V surface-mount silicon rectifier diode in DO-214AB (SMC) package, featuring glass-passivated junction, 1.1V max forward voltage at 15A, 350A peak surge capability, and J-STD-020 Level 1 moisture sensitivity - used in high-reliability freewheeling and SMPS output stages.
For engineers reviewing the S15MCHM6G datasheet, S15MCHM6G pinout, S15MCHM6G application, or S15MCHM6G equivalent, key selection criteria include VRRM = 1000V, IF = 15A continuous, RθJL = 8°C/W thermal resistance, and RoHS/halogen-free compliance for industrial power conversion designs.
Technical Context
This single-die standard recovery rectifier operates with a maximum junction temperature of 150°C and supports repetitive reverse voltages up to 1000V. Its glass-passivated chip junction ensures stable reverse leakage (<1µA at 25°C, <250µA at 125°C) and robust surge immunity under 8.3ms half-sine transients.
The DO-214AB (SMC) package delivers low thermal resistance (RθJL = 8°C/W) and matte tin-plated leads compliant with J-STD-002 solderability. Polarity is marked by a cathode band; weight is 0.270g.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 1000 V - Maximum repetitive reverse blocking voltage; defines safe operating ceiling in high-voltage DC bus or flyback clamp circuits |
| IF | 15 A - Continuous forward current rating; determines heatsink sizing and conduction loss in 100–500 kHz SMPS outputs |
| IFSM | 350 A - Peak non-repetitive surge current (8.3 ms); enables robustness against line transients and startup inverter currents |
| VF | ≤1.1 V @ 15 A, 25°C - Forward voltage drop directly impacts conduction loss and thermal rise in high-current rectification paths |
| RθJL | 8 °C/W - Junction-to-lead thermal resistance; enables direct PCB copper pour thermal coupling without additional heatsink in many 15A applications |
| CJ | 93 pF @ 1 MHz, 4 V - Junction capacitance affects high-frequency switching noise and EMI filter design in >100 kHz converters |
Pinout & Package
Package: DO-214AB (SMC), surface-mount, single-anode/single-cathode configuration. Cathode indicated by molded band. Matte tin-plated leads, UL 94V-0 molding compound, JESD201 Class 2 whisker resistant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to lower-potential side (e.g., transformer secondary center-tap or switch node return) in bridge or freewheeling configurations |
| Cathode | Forward current exit point | Connected to output rail or energy storage capacitor; polarity band identifies this terminal for correct PCB layout orientation |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Enables stable long-term reverse leakage performance and enhanced humidity resistance without hermetic sealing |
| Level 1 moisture sensitivity | Eliminates bake requirement prior to reflow; compatible with standard SMT assembly lines without special handling |
| RoHS + halogen-free | Meets IEC 61249-2-21 and EU RoHS directives; supports environmentally regulated industrial and telecom end equipment |
| 350A surge rating | Withstands repeated inrush and fault currents in UPS, motor drives, and solar inverters without degradation |
Applications
| Industrial SMPS Output Rectification | Uninterruptible Power Supply (UPS) Freewheeling |
|---|---|
Use Scenario: High-efficiency 1–3 kW AC/DC front-end or DC/DC stage where 1000V blocking and 15A average current are required. IC Role / Device Role / Timing Role: Primary output rectifier in full-wave or center-tapped configurations; handles continuous conduction mode (CCM) operation. Use Value: Low VF (≤1.1 V) reduces conduction loss by ~15% vs. comparable 1000V diodes rated at 1.25 V, improving system efficiency at full load. | Use Scenario: Bidirectional energy path in double-conversion UPS during battery backup mode, requiring fast recovery and high surge tolerance. IC Role / Device Role / Timing Role: Freewheeling diode across IGBTs or MOSFETs in inverter leg; clamps inductive kickback during switching transitions. Use Value: 350A IFSM withstands 10× nominal current surges during grid failure events, preventing catastrophic failure during battery discharge peaks. |
| Solar Inverter DC Link Clamp | Telecom Rectifier Module |
Use Scenario: DC link snubber or clamp circuit in string inverters exposed to lightning-induced transients and PV array voltage spikes. IC Role / Device Role / Timing Role: Voltage-clamping rectifier in passive clamp networks; absorbs transient energy during overvoltage events. Use Value: 1000V VRRM provides 20% margin above 800V DC link rails, ensuring reliability under worst-case PV open-circuit conditions. | Use Scenario: 48 V output rectification in telecom shelf power systems with strict thermal and footprint constraints. IC Role / Device Role / Timing Role: Secondary-side synchronous rectifier replacement in legacy designs; used where Schottky alternatives lack sufficient VRRM. Use Value: DO-214AB footprint enables drop-in replacement on existing layouts; RθJL = 8°C/W allows direct thermal coupling to 2 oz copper, reducing need for external heatsinks. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1510DJF | 15A, 1000V, TO-220AC package; higher RθJA (50°C/W), no Level 1 MSL rating | Requires heatsink mounting and baking before reflow; unsuitable for lead-free SMT-only lines | Select when discrete heatsinking is available and manual assembly is acceptable |
| VS-15EWH10-M3 | 15A, 1000V, DO-214AB; VF = 1.25 V max @ 15A; RθJL = 9.5°C/W | Higher conduction loss and slightly reduced thermal coupling efficiency in compact PCB layouts | Select when Vishay supply chain alignment or qualification history is prioritized over minimal VF advantage |
Compared with STTH1510DJF and VS-15EWH10-M3, the S15MCHM6G offers superior SMT manufacturability (MSL Level 1), lowest forward voltage (≤1.1 V), and best thermal coupling (RθJL = 8°C/W), making it optimal for space-constrained, high-efficiency industrial power modules.

FAQ
What is the maximum junction temperature rating for the S15MCHM6G?
The S15MCHM6G has a maximum junction temperature (TJ) rating of +150°C, verified per absolute maximum ratings in the official Taiwan Semiconductor datasheet. This allows operation in high-ambient environments such as enclosed industrial power enclosures or solar inverter chassis. Derating curves confirm usable current capacity down to 0A at 150°C ambient when mounted on standard FR-4 with 1-inch² 2 oz copper pour.
Does the S15MCHM6G meet RoHS and halogen-free requirements?
Yes, the S15MCHM6G is fully RoHS compliant and halogen-free per IEC 61249-2-21. Taiwan Semiconductor confirms this in the product specification sheet (Version C2102), and the device carries appropriate marking per JEDEC standards. These certifications apply to the entire S15GC–S15MC family, including the S15MCHM6G variant.
What is the moisture sensitivity level (MSL) of the S15MCHM6G, and does it require baking before reflow?
The S15MCHM6G is rated MSL Level 1 per J-STD-020, meaning it may be stored indefinitely at ≤30°C/60% RH and placed directly into reflow without preconditioning or baking. This eliminates process steps in high-volume SMT lines and avoids moisture-induced popcorn cracking risks during lead-free reflow profiles.
How does the forward voltage of the S15MCHM6G compare to similar 1000V rectifiers?
The S15MCHM6G specifies a maximum forward voltage (VF) of 1.1 V at 15 A and 25°C - among the lowest in its class. Competing 1000V/15A rectifiers like VS-15EWH10-M3 specify 1.25 V max, resulting in ~2.25 W higher conduction loss at full load. This difference directly improves thermal margin and system efficiency in thermally constrained designs.
Is the S15MCHM6G pin-compatible with other devices in the S15GC–S15MC family?
Yes, all S15GC–S15MC variants, including S15MCHM6G, share identical DO-214AB (SMC) packaging, pinout, and mechanical dimensions. The only functional difference is VRRM: S15GC = 400V, S15JC = 600V, S15KC = 800V, S15MC = 1000V. This allows board-level voltage scalability without layout changes - S15MCHM6G replaces S15KCHM6G or S15JCHM6G with no PCB modification.
