Product details
Overview
SRAF16100 from Taiwan Semiconductor is a 16A, 100V Schottky barrier rectifier in ITO-220AC package, featuring 0.92V forward voltage at 16A/25°C, 5mA reverse current at 100V/125°C, and 10,000 V/µs dv/dt rating. It serves as primary output rectifier in high-efficiency DC-DC converters and industrial SMPS.
For engineers reviewing the SRAF16100 datasheet, SRAF16100 pinout, SRAF16100 application, or SRAF16100 equivalent, key selection criteria include its 100V VRRM rating, 275A IFSM surge capability, junction-to-case thermal resistance of 4°C/W, AEC-Q101 qualification option (SRAF16100H), and compatibility with lead-free reflow soldering per J-STD-002.
Technical Context
This single-die Schottky rectifier uses guard ring technology for over-voltage protection and operates with a maximum junction temperature of 150°C. Its low forward voltage minimizes conduction loss in high-frequency switching topologies, while the 10,000 V/µs critical dv/dt supports fast-switching MOSFET-based converters.
The ITO-220AC package provides direct case-to-heatsink thermal path with 0.56 N·m mounting torque limit and UL 94V-0 molding compound. Polarity is marked on the device body, and terminals are matte tin-plated for reliable solderability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Maximum repetitive reverse voltage before breakdown; defines safe operating range in 48V–72V bus applications |
| IF | 16 A - Continuous average forward current; supports sustained power delivery in 200–300W converter outputs |
| VF @ 16A, 25°C | 0.92 V - Low conduction loss enabling >92% efficiency at full load in 100kHz+ SMPS designs |
| IFSM | 275 A - Non-repetitive surge current handling; withstands inrush and fault transients without failure |
| RθJC | 4 °C/W - Thermal resistance from junction to case; enables 32W dissipation with ≤125°C junction rise at 25°C heatsink |
| IR @ 100V, 125°C | 5 mA - Reverse leakage at max rated temperature; ensures stable blocking under thermal stress |
| dv/dt | 10,000 V/µs - Critical rate of rise tolerance; prevents false turn-on in hard-switched synchronous rectifier circuits |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-16CTH10-M3 | 16A, 100V, TO-220AC package, VF = 0.87V @ 16A, RθJC = 3.5°C/W, no AEC-Q101 option | Higher thermal performance but lacks automotive qualification; UL recognized only for discrete diodes | Preferred where thermal margin is critical and automotive compliance is not required |
| ON Semiconductor MBR16100CT | 16A, 100V, TO-220AB dual common-cathode configuration, VF = 0.95V @ 16A, RθJC = 4.5°C/W | Dual-diode layout enables center-tapped transformer designs; not single-die like SRAF16100 | Selected for dual-output or interleaved converter topologies requiring matched pair characteristics |

FAQ
What is the maximum junction temperature rating for the SRAF16100?
The SRAF16100 has a maximum junction temperature (TJ) rating of +150°C, validated across its full operating voltage range. This allows continuous operation in high-ambient environments such as enclosed industrial power supplies or automotive under-hood auxiliary systems. The SRAF16100 maintains specified electrical parameters-including 5mA reverse current at 100V and 125°C-within this thermal envelope.
Is the SRAF16100 available in an AEC-Q101 qualified version?
Yes, the SRAF16100H is the AEC-Q101 qualified variant of the SRAF16100, meeting stress test requirements for temperature cycling, humidity, mechanical shock, and ESD. It shares identical electrical specifications and ITO-220AC mechanical form factor with the standard SRAF16100, enabling drop-in qualification upgrade without layout change.
What is the forward voltage specification for the SRAF16100 at elevated temperature?
The SRAF16100 exhibits a typical forward voltage of 0.92V at 16A and 25°C. At 100°C junction temperature, VF increases to approximately 0.85V due to negative temperature coefficient of Schottky diodes. This behavior is confirmed in the "Typical Forward Characteristics" curve (Fig.4) of the official SRAF1620–SRAF16100 datasheet (Version J2105).
Does the SRAF16100 have UL recognition, and what is the file number?
Yes, the SRAF16100 is UL Recognized under File #E-326243, covering its use in end-product safety certifications. This applies to both standard and AEC-Q101 versions and confirms compliance with UL 60950-1 and UL 62368-1 for power supply applications, including adapters and industrial SMPS.
How does the guard ring feature improve reliability in the SRAF16100?
The guard ring in the SRAF16100 mitigates electric field concentration at the die edge, preventing premature avalanche breakdown during voltage transients. This design enhances ruggedness against line surges and ringing in high-dv/dt switching circuits, extending operational lifetime in demanding applications such as telecom rectifiers and server PSUs where voltage overshoot exceeds 120% of VRRM.
