Product details
Overview
SRAF10150 from Taiwan Semiconductor is a 10A, 150V Schottky barrier rectifier in ITO-220AC package, featuring 0.95V forward voltage at 10A/25°C, 5mA reverse leakage at 125°C, and 200A surge capability - deployed in high-efficiency DC-DC converters and automotive-grade SMPS.
For engineers reviewing the SRAF10150 datasheet, SRAF10150 pinout, SRAF10150 application, or SRAF10150 equivalent, key selection factors include its AEC-Q101 qualification option (SRAF10150H), 4°C/W junction-to-case thermal resistance, and 150V VRRM rating with guard ring over-voltage protection.
Technical Context
This single-die Schottky rectifier operates with a maximum junction temperature of +150°C and supports repetitive peak reverse voltages up to 150V. Its low VF (0.95V) and high IFSM (200A) enable efficient power conversion in compact, thermally constrained designs.
The device uses matte tin-plated leads compliant with J-STD-002, meets UL 94V-0 flammability, and incorporates a guard ring structure for enhanced dv/dt immunity (10,000 V/µs) - critical for noisy switching environments like on-board chargers and industrial DC supplies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 150 V - maximum repetitive reverse blocking voltage; defines safe operating limit in high-voltage DC bus applications |
| IF | 10 A - continuous average forward current; sets steady-state power handling capacity at case temperature ≤75°C |
| VF @ 10A, 25°C | 0.95 V - forward conduction loss directly impacts system efficiency and thermal design margin |
| IR @ 150V, 125°C | 5 mA - high-temperature reverse leakage; determines standby power loss and reliability in hot ambient conditions |
| RθJC | 4 °C/W - thermal resistance from junction to case; enables accurate heatsink sizing for 10A operation |
| IFSM | 200 A - non-repetitive surge current rating; supports robustness against line transients and inrush events |
Pinout & Package
Package: ITO-220AC - insulated TO-220 variant with isolated tab, UL 94V-0 molding compound, and 0.56 N·m max mounting torque. Polarity marked on device body.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Lead 1) | Forward current entry point | Connected to input/high-side rail; requires thermal relief and current-carrying trace width ≥1.5 mm |
| Cathode (Lead 2) | Forward current exit point | Connected to output/low-side rail; serves as primary heat path to heatsink via isolated tab |
| Isolated Tab (Case) | Thermal interface only | Electrically isolated from both terminals; must be mounted to heatsink without electrical shorting |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring structure | Enables 10,000 V/µs dv/dt immunity - prevents false turn-on during fast-switching transitions in SiC/GaN-based converters |
| AEC-Q101 qualification option | Available as SRAF10150H - validated for automotive under-hood temperature cycling and mechanical shock requirements |
| UL Recognized (E-326243) | Confirms safety compliance for end-equipment certification in AC/DC adapters and industrial power supplies |
| Halogen-free construction | Meets IEC 61249-2-21 - satisfies environmental compliance for RoHS and WEEE-regulated markets |

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-10EWH15-M3 | 10A, 150V, VF = 0.89V @ 10A, RθJC = 3.5°C/W, DO-201AD package | Lower thermal resistance but axial leaded - requires through-hole PCB layout and lacks isolated tab for heatsinking | Preferred for cost-sensitive, non-heatsinked low-power adapters; not suitable for surface-mount or high-density thermal designs |
| ON Semiconductor MBR10150CT | 10A, 150V dual common-cathode die in TO-220AB, VF = 0.92V @ 10A, RθJC = 5.0°C/W | Dual configuration enables center-tap rectification; higher thermal resistance limits power density vs. single-die ITO-220AC | Used when dual-output or split-rail rectification is needed; requires redesign for single-diode replacement due to pinout and thermal path differences |
Compared with VS-10EWH15-M3 and MBR10150CT, the SRAF10150 offers superior thermal management via its isolated-tab ITO-220AC package and AEC-Q101 qualification path, making it optimal for space-constrained, high-reliability automotive and industrial power stages where heatsink integration and transient robustness are critical.

FAQ
What is the maximum junction temperature rating for the SRAF10150?
The SRAF10150 has a maximum junction temperature (TJ) rating of +150°C, confirmed in the Absolute Maximum Ratings table. This allows operation in high-ambient environments such as under-hood automotive systems or enclosed industrial power supplies, provided thermal design maintains junction temperature within this limit. The SRAF10150 datasheet specifies derating curves starting at 75°C case temperature.
Does the SRAF10150 have AEC-Q101 qualification?
The base SRAF10150 is not AEC-Q101 qualified; however, the variant SRAF10150H is explicitly listed as AEC-Q101 qualified in the Ordering Information section. This qualification covers temperature cycling, mechanical shock, and humidity testing required for automotive under-hood applications. Always verify the "H" suffix when specifying for automotive use.
What is the forward voltage drop of the SRAF10150 at rated current?
The SRAF10150 exhibits a typical forward voltage (VF) of 0.95 V at IF = 10 A and TJ = 25°C, as specified in the Electrical Specifications table. This value increases with junction temperature and must be evaluated using the derating curve in Figure 4 of the datasheet for accurate thermal modeling in real-world operation.
How does the guard ring feature benefit the SRAF10150 in practical designs?
The guard ring in the SRAF10150 improves edge termination robustness, enabling a critical rate of rise of off-state voltage (dv/dt) of 10,000 V/µs. This prevents spurious conduction during fast voltage transients in high-frequency switch-mode topologies - especially important in GaN-based converters where rapid switching edges can induce false turn-on in inadequately protected rectifiers like the SRAF10150.
What packaging and marking details apply to the SRAF10150?
The SRAF10150 is supplied in ITO-220AC package with matte tin-plated leads, packed 50 units per tube. Marking includes "SRAF10150", green compound indicator (G), date code (YWW), and factory code (F). Polarity is marked on the device body, and the isolated tab is electrically independent of both leads - verified in the Mechanical Data and Marking Diagram sections.
