Product details
Overview
SRAS2060H from Taiwan Semiconductor is a 20A, 60V Schottky barrier rectifier in TO-263AB (D2PAK) package, designed for low-loss DC/DC conversion and freewheeling applications. It features 0.70V forward voltage at 20A/25°C, 330A surge capability, 1.5°C/W junction-to-case thermal resistance, and AEC-Q101 qualification for automotive use.
For engineers reviewing the SRAS2060H datasheet, SRAS2060H pinout, SRAS2060H application, or SRAS2060H equivalent, this device is selected for high-efficiency, high-current switching power supplies where low VF, robust surge handling, and automotive-grade reliability are required.
Technical Context
The SRAS2060H employs a single-die Schottky structure optimized for low forward voltage and fast recovery-critical for minimizing conduction loss in high-frequency converters. Its guard ring design enhances overvoltage ruggedness, while the TO-263AB package enables high thermal dissipation with surface-mount compatibility.
Rated for TJ = –55°C to +150°C and moisture sensitivity level 1 (J-STD-020), it supports automated placement and meets JESD201 Class 2 whisker resistance. Reverse leakage is limited to 500 µA at 60 V and 25°C, rising to 10 mA at 125°C.

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-20CPH06-M3 | Same 60 V VRRM, 20 A IF, TO-263AB package; VF = 0.69 V @ 20 A, slightly lower IR (300 µA) | No AEC-Q101 qualification; intended for industrial/commercial use only | Select when automotive qualification is not required and tighter IR spec is prioritized |
| ON Semiconductor SB2060 | 60 V VRRM, 20 A IF, TO-263AB; VF = 0.72 V @ 20 A, IFSM = 250 A, RθJC = 1.8 °C/W | AEC-Q101 qualified but lower surge and thermal performance | Select when footprint compatibility is critical but peak surge and thermal margin are less demanding |
Compared with VS-20CPH06-M3 and SB2060, the SRAS2060H delivers superior surge robustness (330 A vs. 250–300 A) and thermal performance (1.5 °C/W vs. ≥1.8 °C/W), making it preferred for automotive and high-reliability industrial power stages where transient immunity and thermal headroom are critical.

FAQ
What is the maximum junction temperature rating for the SRAS2060H?
The SRAS2060H has a maximum junction temperature (TJ) rating of +150°C, with operational range from –55°C to +150°C. This rating is validated per AEC-Q101 stress testing and supports use in under-hood automotive environments where ambient temperatures exceed 105°C. Derating curves in the datasheet define safe IF limits versus case temperature.
Is the SRAS2060H pin-compatible with other devices in the SRAS20xxH series?
Yes, all SRAS20xxH devices-including SRAS2060H-share identical TO-263AB (D2PAK) package dimensions, pinout, and thermal pad layout. Voltage ratings differ (20 V to 150 V), but mechanical and soldering interfaces are fully interchangeable, enabling design reuse across voltage variants.
Does the SRAS2060H require a heatsink in 20 A continuous operation?
At 20 A continuous, the SRAS2060H requires external thermal management: its RθJC of 1.5 °C/W means even with ideal case-to-heatsink interface, junction temperature will exceed 150°C without sufficient heatsinking. A minimum 25 cm² copper pour or dedicated heatsink is recommended to maintain TJ ≤ 130°C at full load.
What is the reverse leakage current specification for SRAS2060H at elevated temperature?
The SRAS2060H specifies IR ≤ 10 mA at 60 V and TJ = 125°C. At 25°C, IR is ≤ 500 µA. This elevated leakage at high temperature is typical for Schottky diodes and must be accounted for in low-power standby designs where reverse-biased leakage could affect system quiescent current.
How does the guard ring feature improve reliability of the SRAS2060H?
The guard ring in the SRAS2060H provides enhanced edge termination that suppresses premature avalanche breakdown at the die periphery. This increases effective overvoltage ruggedness beyond the rated 60 V VRRM, improving robustness against transient spikes and layout-induced field concentration-especially important in automotive load-dump scenarios.
