Taiwan Semiconductor Corporation SR010

Overview

SR010 from Taiwan Semiconductor is a 100 V, 0.5 A Schottky barrier rectifier in DO-204AL (DO-41) package, featuring 0.85 V forward voltage at 0.5 A and 100 µA reverse leakage at 25°C, optimized for high-efficiency DC/DC converters and automotive-grade power supplies.

For engineers reviewing the SR010 datasheet, SR010 pinout, SR010 application, or SR010 equivalent, key selection criteria include its 100 V repetitive peak reverse voltage, AEC-Q101 qualification (H-suffix variant), 2 mA reverse current at 125°C, 65 pF junction capacitance, and thermal resistance of 50 °C/W - all critical for compact, thermally constrained switching power designs.

Technical Context

The SR010 implements a single-die Schottky structure with guard ring overvoltage protection, enabling robust surge handling (30 A IFSM) while maintaining low conduction loss. Its junction temperature rating extends to +150°C, supporting operation in under-hood automotive environments without derating below 0.5 A up to 75°C ambient.

Electrical behavior is defined by voltage-dependent VF and IR trade-offs: at 100 V VRRM, VF rises to 0.85 V (vs. 0.55 V for SR002), and IR drops to 100 µA at 25°C but increases to 2 mA at 125°C - reflecting optimized high-voltage Schottky design with controlled leakage/speed balance.

Key Specifications

Manufacturer

Taiwan Semiconductor Corporation (TSC) is a vertically integrated analog and discrete semiconductor manufacturer headquartered in Hsinchu, Taiwan, specializing in power devices, rectifiers, and protection components.

The SR002–SR010 series was developed to deliver AEC-Q101-qualified Schottky rectifiers with scalable voltage ratings (20–100 V) and consistent DO-41 packaging for automotive and industrial power supply designers needing drop-in reliability upgrades.

FAQ

What is the maximum junction temperature rating for SR010?

The SR010 has a maximum junction temperature (TJ max) of +150°C, validated per AEC-Q101 stress test conditions. This allows uninterrupted 0.5 A operation up to 75°C ambient in free-air mounting, and supports under-hood automotive deployment where ambient temperatures exceed 105°C. The SR010 datasheet specifies derating begins only above 75°C ambient.

Is SR010 AEC-Q101 qualified, and how is this reflected in the part marking?

Yes, SR010 is AEC-Q101 qualified when ordered with the "H" suffix (e.g., SR010H). The qualification applies to the entire SR002–SR010 family in DO-41 package. Marking includes the "H" code and date/lot traceability per JESD standards; standard SR010 (no H) is not AEC-Q101 certified.

What is the forward voltage of SR010 at 0.5 A and 125°C junction temperature?

The SR010 forward voltage (VF) is specified at 0.85 V maximum at 0.5 A and 25°C. While the datasheet does not provide a direct VF value at 125°C, typical curves show VF decreases ~2 mV/°C - resulting in approximately 0.67 V at 125°C. This lower VF improves conduction efficiency at elevated temperatures.

How does SR010's reverse leakage compare to SR005 or SR006 at high temperature?

At 125°C and rated VR, SR010 exhibits 2 mA reverse current, whereas SR005/SR006 are rated at 5 mA under identical conditions. This 2.5× lower IR reflects SR010's optimized high-voltage Schottky process, directly improving light-load efficiency and thermal stability in high-temperature DC/DC applications.

Can SR010 be used as a direct replacement for SR006 in an existing design?

No - SR010 (100 V VRRM) and SR006 (60 V VRRM) differ significantly in reverse voltage rating and forward characteristics. Substituting SR010 for SR006 introduces unnecessary voltage margin and slightly higher VF (0.85 V vs. 0.70 V), potentially increasing conduction loss. Use only if the design requires ≥100 V blocking capability.
