Product details
Overview
SRAF1660 from Taiwan Semiconductor is a 16A, 60V Schottky barrier rectifier in ITO-220AC package, featuring low forward voltage (0.70 V at 16 A, 25°C), high surge current capability (275 A), and junction temperature rating up to +150°C. It serves as a primary output rectifier in high-efficiency DC/DC converters and industrial SMPS.
For engineers reviewing the SRAF1660 datasheet, SRAF1660 pinout, SRAF1660 application, or SRAF1660 equivalent, key selection criteria include its 60 V repetitive peak reverse voltage, 4°C/W junction-to-case thermal resistance, AEC-Q101 qualification option (SRAF1660H), and suitability for high-current, low-loss power conversion stages.
Technical Context
This single-die Schottky rectifier uses a guard ring structure for enhanced over-voltage robustness and meets UL 94V-0 flammability requirements. Its 10,000 V/µs critical rate of rise of off-state voltage supports fast-switching topologies without spurious turn-on.
Designed for operation from –55°C to +150°C junction temperature, it delivers stable reverse leakage ≤10 mA at 125°C and ≤10 mA at 100°C under rated 60 V reverse bias - enabling reliable performance in thermally demanding power supplies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 60 V - Maximum repetitive reverse blocking voltage; defines safe operating range in flyback/freewheeling paths |
| IF | 16 A - Continuous average forward current; sets minimum heatsink sizing for steady-state conduction |
| IFSM | 275 A - Non-repetitive surge rating; withstands inrush and fault currents in 8.3 ms half-sine waveform |
| VF @ 16A, 25°C | 0.70 V - Low conduction loss directly reduces power dissipation and improves system efficiency |
| RθJC | 4°C/W - Thermal resistance from junction to case; enables direct mounting to heatsink with predictable temperature rise |
| TJ max | +150°C - Extended junction temperature rating supports compact, high-power-density designs |
| dv/dt | 10,000 V/µs - High critical rate-of-rise immunity prevents false triggering in high-dV/dt switching environments |
Pinout & Package
Package: ITO-220AC - 3-terminal through-hole package with isolated tab (cathode-connected), matte tin-plated leads compliant with J-STD-002 solderability, and UL Recognized File #E-326243.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Input current terminal | Connected to source-side node (e.g., transformer secondary or switch node); carries full load current into device |
| Cathode | Output current terminal | Connected to output rail; electrically tied to metal tab for low-inductance, high-current return path |
| Tab (Case) | Thermal & electrical cathode | Electrically active cathode terminal; must be electrically isolated from chassis unless circuit design requires common-cathode configuration |

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-16CTQ060 | Same 60 V VRRM, 16 A IF, but TO-220AC package with RθJC = 3.5°C/W; VF = 0.68 V @ 16 A | Higher thermal efficiency but lacks AEC-Q101 option and UL recognition | Select for maximum thermal performance where automotive qualification is not required |
| ON Semiconductor MBR1660CT | 60 V VRRM, dual-die center-tap configuration in TO-220AB; VF = 0.72 V @ 16 A per anode | Not single-die; requires different PCB layout and gate drive coordination in synchronous designs | Choose only when dual-output or center-tapped topology is mandated |
Compared with VS-16CTQ060 and MBR1660CT, the SRAF1660 offers unique combination of UL recognition, AEC-Q101 availability, and guard ring protection - making it preferred for certified industrial and automotive power supplies where reliability and safety documentation are mandatory.

FAQ
What is the maximum junction temperature rating for the SRAF1660?
The SRAF1660 has a maximum junction temperature (TJ max) of +150°C, verified per absolute maximum ratings table. This allows operation in high-ambient environments such as enclosed industrial power supplies or under-hood automotive modules. Derating curves confirm usable current capacity down to 125°C case temperature, and the SRAF1660 maintains specified IR and VF performance within this range.
Is the SRAF1660 pin-compatible with other ITO-220AC Schottky rectifiers?
Yes - the SRAF1660 uses standard ITO-220AC mechanical dimensions and 3-pin terminal layout (anode, cathode, isolated tab). It shares identical mounting hole spacing, lead pitch, and tab orientation with industry-standard ITO-220AC rectifiers like VS-16CTQ060 and STPS16H60CG. However, electrical characteristics (e.g., VF, IR, dv/dt) differ, so functional validation is required before substitution.
Does the SRAF1660 have AEC-Q101 qualification?
The base SRAF1660 is not AEC-Q101 qualified, but the variant SRAF1660H is explicitly listed in the ordering information as AEC-Q101 qualified. This qualification covers temperature cycling, humidity testing, and mechanical shock per AEC-Q101 Rev D. For automotive applications, specify SRAF1660H - the "H" suffix denotes full qualification, while SRAF1660 alone does not carry this certification.
What is the forward voltage drop of the SRAF1660 at full rated current?
The SRAF1660 exhibits a typical forward voltage (VF) of 0.70 V at IF = 16 A and TJ = 25°C, per electrical specifications table. At elevated temperatures (e.g., TJ = 100°C), VF decreases slightly to ~0.62 V. This low VF directly reduces conduction loss to approximately 11.2 W at 16 A, enabling efficient thermal management in high-current applications.
How does the guard ring feature improve reliability of the SRAF1660?
The guard ring in the SRAF1660 provides edge termination that suppresses electric field crowding at the die periphery, increasing resistance to avalanche-induced degradation during transient over-voltage events. This structural enhancement allows the SRAF1660 to sustain rated VRRM without derating under fast-rising transients - a key advantage over non-guarded Schottky rectifiers in noisy switching environments.
