Product details
Overview
SRAF8150HC0G from Taiwan Semiconductor is an AEC-Q101-qualified 8A, 150V Schottky barrier rectifier in ITO-220AC package, featuring 0.95V forward voltage at 8A/25°C, 5 °C/W junction-to-case thermal resistance, and 150A surge current capability. It serves as a high-efficiency output rectifier in automotive-grade DC-DC converters and industrial SMPS.
For engineers reviewing the SRAF8150HC0G datasheet, SRAF8150HC0G pinout, SRAF8150HC0G application, or SRAF8150HC0G equivalent, key selection factors include its 150V VRRM, AEC-Q101 qualification, low VF at high IF, TJ max of +150°C, and ITO-220AC mounting compatibility with 0.56 N·m torque limit.
Technical Context
This discrete Schottky diode uses a single-die construction with guard ring for over-voltage protection and meets UL 94V-0 flammability rating. Its 10,000 V/µs dv/dt rating supports fast-switching topologies, and matte tin-plated leads comply with J-STD-002 solderability.
The device operates across -55°C to +150°C junction temperature range and delivers 5 mA reverse leakage at 150V and 125°C. Thermal performance is characterized by RθJC = 5 °C/W, enabling stable operation under sustained 8A DC load with appropriate heatsinking.

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-8EWH150N-M3/45 | Same ITO-220AC package, 8A/150V, VF = 0.93V @ 8A, but rated to +175°C TJ max and not AEC-Q101 qualified | Preferred for industrial UPS where extended temperature margin is critical; unsuitable for automotive qualification-critical designs | Select when higher junction temperature headroom is needed and AEC-Q101 is not mandated |
| ON Semiconductor SB8150E | ITO-220AC, 8A/150V, VF = 0.97V @ 8A, AEC-Q101 qualified, but RθJC = 6.5 °C/W and IR = 200 µA @ 150V/25°C | Better suited for cost-sensitive automotive infotainment supplies where slightly higher leakage is acceptable | Choose when supply chain diversification is required and 1.5 °C/W higher thermal resistance is tolerable |
Compared with VS-8EWH150N-M3/45 and SB8150E, the SRAF8150HC0G uniquely balances AEC-Q101 compliance, 0.95V VF, 5 °C/W thermal resistance, and 100 µA low leakage-making it optimal for thermally constrained, qualification-driven automotive and industrial power designs.

FAQ
What does the 'H' suffix in SRAF8150HC0G indicate?
The 'H' in SRAF8150HC0G denotes AEC-Q101 qualification, confirming that the SRAF8150HC0G has passed rigorous automotive-grade stress testing including high-temperature operating life, temperature cycling, and humidity testing. This makes the SRAF8150HC0G suitable for under-hood and other automotive power systems where reliability is mission-critical.
Is the tab of SRAF8150HC0G electrically isolated?
Yes, the tab of the SRAF8150HC0G is electrically isolated from both anode and cathode terminals, as confirmed by its ITO-220AC package designation. This isolation allows direct mechanical mounting to a grounded heatsink without short-circuit risk, simplifying thermal management in high-density power designs using the SRAF8150HC0G.
What is the maximum mounting torque for SRAF8150HC0G?
The maximum recommended mounting torque for the SRAF8150HC0G is 0.56 N·m, as specified in the mechanical data section of the official Taiwan Semiconductor datasheet. Exceeding this torque may damage the ITO-220AC package seal or compromise internal wire bonds, affecting long-term reliability of the SRAF8150HC0G in production assemblies.
How does SRAF8150HC0G perform at elevated junction temperatures?
At TJ = 125°C, the SRAF8150HC0G exhibits 5 mA reverse leakage current under rated 150V reverse bias, and its forward voltage drops slightly due to negative temperature coefficient. The +150°C maximum junction temperature rating ensures the SRAF8150HC0G remains functional in demanding thermal environments typical of automotive and industrial power systems.
Does SRAF8150HC0G meet halogen-free standards?
Yes, the SRAF8150HC0G complies with IEC 61249-2-21 for halogen-free materials, meaning its molding compound contains no chlorine or bromine-based flame retardants. This requirement is explicitly stated in the features list and supports environmentally compliant manufacturing for the SRAF8150HC0G in RoHS-aligned production lines.
