Taiwan Semiconductor Corporation SR006

Overview

SR006 from Taiwan Semiconductor is a 0.5A, 60V Schottky barrier rectifier in DO-204AL (DO-41) package, featuring 0.70V max forward voltage at 0.5A/25°C, 5 mA max reverse current at 100°C, 80 pF junction capacitance at 1 MHz/4V, and 30 A surge capability - used in compact DC-DC converters requiring low-loss unidirectional conduction.

For engineers reviewing the SR006 datasheet, SR006 pinout, SR006 application, or SR006 equivalent, key selection criteria include its 60 V repetitive peak reverse voltage, AEC-Q101-qualified variants (e.g., SR006H), thermal resistance of 50°C/W, cathode-band polarity marking, and compatibility with J-STD-002 soldering standards.

Technical Context

The SR006 operates as a single-die Schottky rectifier with guard ring structure for overvoltage protection and is rated for junction temperatures up to +150°C. Its low VF and high IFSM support high-efficiency power conversion in space-constrained topologies.

Electrical behavior is defined across temperature: IR rises to 5 mA at TJ = 100°C (VR = 60 V), while CJ remains stable at 80 pF under 1 MHz/4 V bias - enabling predictable switching loss estimation in high-frequency SMPS designs.

Equivalent & Alternatives

The following parts are listed as comparable options for similar Schottky rectifier applications.

Compared with VS-2EY60-M3 and SB0560, the SR006 offers higher surge robustness (30 A), optional AEC-Q101 qualification (SR006H), and slightly lower VF - making it preferred for automotive and industrial DC-DC where reliability margins and thermal performance are prioritized.

Availability

SR006 is available at Aetrix Electronics and suitable for AC-DC adapters, automotive body control modules, and industrial DC-DC converters requiring stable component supply, consistent lead-time visibility, and long-term obsolescence management.

Supply support for SR006 includes scheduled delivery planning, volume procurement assistance, BOM continuity management, traceable sourcing, and lifecycle availability coordination for OEM customers, industrial embedded developers, connected-device designers, and electronics production programs.

Manufacturer

Taiwan Semiconductor Corporation (TSC) is a vertically integrated analog and discrete semiconductor manufacturer headquartered in Hsinchu, Taiwan, serving global power and automotive markets since 1979.

The SR006 belongs to TSC's SR-series Schottky rectifier family, engineered for high-efficiency, low-profile power conversion in cost-sensitive and reliability-critical applications including automotive subsystems and industrial power supplies.

FAQ

What is the maximum junction temperature rating for SR006?

The SR006 has a maximum junction temperature (TJ) rating of +150°C, validated per absolute maximum ratings table. This allows operation in high-ambient environments such as under-hood automotive locations or enclosed industrial power supplies. Derating curves confirm usable current capacity down to 0.3 A at 125°C ambient, assuming RθJA = 50°C/W. The SR006 datasheet specifies storage temperature range as –55°C to +150°C.

Is SR006 available in an AEC-Q101 qualified version?

Yes, the AEC-Q101 qualified version of SR006 is designated SR006H and shares identical electrical and thermal specifications. It undergoes additional stress testing per AEC-Q101 standard, including HTGB, HTRB, and temperature cycling. SR006H is marked with "H" suffix and packaged in tape-and-reel (5,000 pcs) or ammo box (3,000 pcs) formats - both fully traceable and automotive PPAP-ready.

What is the reverse leakage current of SR006 at elevated temperature?

At TJ = 100°C and rated VR = 60 V, the SR006 exhibits a maximum reverse current (IR) of 5 mA, per electrical specifications table. At 25°C, IR is limited to 500 µA. No IR value is specified at 125°C for SR006 - unlike SR002–SR004 which list 10 mA at that condition - confirming its optimized thermal stability for mid-range voltage Schottky devices.

Does SR006 have a halogen-free construction?

Yes, SR006 uses a halogen-free molding compound compliant with IEC 61249-2-21, and is RoHS compliant. This is explicitly stated in the FEATURES section and confirmed in the Mechanical Data table. Lead finish is pure tin, meeting J-STD-002 solderability requirements, and the device passes JESD 201 Class 2 whisker testing - ensuring long-term interconnect reliability in lead-free reflow processes.

What is the junction-to-ambient thermal resistance (RθJA) of SR006?

The SR006 has a typical junction-to-ambient thermal resistance (RθJA) of 50°C/W, measured under standard JEDEC test conditions on FR-4 board with 1 in² copper pad. This value enables accurate thermal modeling for board-level power dissipation - for example, at 0.5 A and 0.70 V VF, power loss is 0.35 W, resulting in ~17.5°C rise above ambient without added heatsinking.
