Product details
Overview
SS15 M2G from Taiwan Semiconductor is a 1A, 50V Schottky barrier surface-mount rectifier in DO-214AC (SMA) package, featuring 0.75V forward voltage at 1A/25°C, 40A peak surge current, and 125°C maximum junction temperature. It serves as a low-loss freewheeling or output rectifier in compact DC/DC converters and AC/DC adapters.
For engineers reviewing the SS15 M2G datasheet, SS15 M2G pinout, SS15 M2G application, or SS15 M2G equivalent, key selection criteria include its 50V VRRM, 0.75V VF @ 1A, 40A IFSM, thermal resistance RθJL = 28°C/W, and DO-214AC mechanical compatibility with automated SMT assembly.
Technical Context
This discrete Schottky diode uses a single-die construction optimized for high-efficiency switching applications. Its guard ring structure provides overvoltage protection, while matte tin-plated leads ensure solderability per J-STD-002 and whisker resistance per JESD 201 Class 2.
The device operates across –55°C to +125°C junction temperature range with moisture sensitivity level 1 (per J-STD-020), and exhibits 10,000 V/µs critical dV/dt rating - enabling reliable operation in fast-switching topologies without snubbers.
Key Specifications
| Parameter | Value and Actual Design Meaning |

| VRRM | 50 V - Maximum repetitive reverse voltage; defines safe blocking capability in 48V-output SMPS designs |
| IF | 1 A continuous - Rated average forward current; supports sustained conduction in 12W–24W power stages |
| VF @ 1A, 25°C | 0.75 V - Low forward drop reduces conduction loss and improves system efficiency vs. standard PN diodes |
| IFSM | 40 A - Peak non-repetitive surge current handling; withstands inrush and transient overload events |
| RθJL | 28 °C/W - Junction-to-lead thermal resistance; enables direct PCB copper pour heat sinking without heatsink |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SS15H (ON Semiconductor) | VRRM = 50 V, VF = 0.72 V @ 1A/25°C, RθJA = 90°C/W | Slightly lower VF but higher thermal resistance; requires larger copper area for same power dissipation | Prefer when lowest possible conduction loss dominates over thermal layout constraints |
| SB150 (Vishay) | VRRM = 50 V, VF = 0.78 V @ 1A/25°C, IFSM = 30 A, RθJL = 30°C/W | Lower surge rating and marginally higher VF; identical DO-214AC footprint and polarity marking | Acceptable where surge margin is relaxed and sourcing flexibility across multiple franchises is prioritized |

FAQ
What is the maximum junction temperature rating for SS15 M2G?
The SS15 M2G has a maximum junction temperature (TJ) rating of +125°C, verified per absolute maximum ratings table in the official Taiwan Semiconductor datasheet R2305. This rating applies under continuous DC forward current conditions and allows operation in thermally demanding environments such as enclosed power adapters or high-ambient industrial modules. Derating is required above 25°C ambient per the forward current derating curve shown in Figure 1 of the SS15 M2G datasheet.
Does SS15 M2G have a halogen-free and RoHS-compliant construction?
Yes, the SS15 M2G is both halogen-free and RoHS compliant, as explicitly stated in the FEATURES section of the Taiwan Semiconductor SS12–SS115 datasheet R2305. The molding compound meets UL 94V-0 flammability rating, and terminals are matte tin plated to satisfy J-STD-002 solderability requirements. These attributes are confirmed for the SS15 M2G variant and apply to all units shipped under this ordering code.
What is the forward voltage of SS15 M2G at 1A and 100°C junction temperature?
The SS15 M2G exhibits a typical forward voltage of 0.65 V at 1A forward current and 100°C junction temperature, per the ELECTRICAL SPECIFICATIONS table in the R2305 datasheet. This value is measured under pulsed conditions (PW = 0.3ms) and reflects real-world performance in thermally stressed operation - critical for evaluating efficiency in high-temperature DC/DC converter designs where the SS15 M2G is commonly deployed.
Is SS15 M2G suitable for use in automotive applications?
No, the SS15 M2G is not qualified for automotive applications. Taiwan Semiconductor explicitly states in the Notice section of the R2305 datasheet that "The products shown herein are not designed for use in medical, life-saving, or life-sustaining applications." While the SS15 M2G meets industrial temperature and reliability standards, it lacks AEC-Q101 qualification, automotive-grade traceability, or extended temperature range certification beyond 125°C - making it unsuitable for under-hood or safety-critical vehicle systems.
What packaging format is used for SS15 M2G?
The SS15 M2G is supplied in 7,500-piece tape-and-reel packaging per the ORDERING INFORMATION section of the R2305 datasheet. This format is optimized for high-speed pick-and-place assembly and complies with EIA-481 standards. The DO-214AC (SMA) package features a cathode band for polarity identification and matte tin-plated leads compatible with lead-free reflow profiles, ensuring reliable solder joint formation in automated SMT lines.
