Product details
Overview
SR1090HC0G from Taiwan Semiconductor is a 10A, 90V AEC-Q101-qualified Schottky barrier rectifier in TO-220AB package with dual-die configuration, 0.85V forward voltage at 5A/25°C, 120A surge capability, and 3°C/W junction-to-case thermal resistance - used in automotive-grade DC-DC converters and industrial SMPS.
For engineers reviewing the SR1090HC0G datasheet, SR1090HC0G pinout, SR1090HC0G application, or SR1090HC0G equivalent, key selection criteria include its 90V VRRM rating, low VF for high-efficiency rectification, AEC-Q101 qualification for automotive reliability, and TO-220AB mechanical compatibility with heatsink mounting.
Technical Context
This Schottky rectifier uses dual-die construction to support parallel current paths while maintaining single-device footprint. Its guard ring structure enables 10,000 V/μs dv/dt rating and overvoltage protection without external snubbers.
Rated for continuous operation up to TJ = 150°C, it delivers 10A average forward current with derating above 75°C case temperature and exhibits only 100 µA reverse leakage at 90V/25°C - critical for standby power optimization in regulated supplies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 90 V - maximum repetitive reverse blocking voltage; defines safe operating margin in 48V–72V bus applications |
| IF(AV) | 10 A - continuous forward current rating at TC = 75°C; supports compact heatsink designs in 100–200W converters |
| VF @ 5A, 25°C | 0.85 V - low conduction loss enabling >92% efficiency in 12V output synchronous rectifier replacements |
| IFSM (8.3ms) | 120 A - non-repetitive surge current handling; withstands inrush during cold-start in automotive ECUs |
| RθJC | 3 °C/W - thermal resistance from junction to case; allows direct bolt-down heatsinking for stable 150°C junction operation |
| IR @ 90V, 25°C | 100 µA - minimal leakage at rated voltage; reduces standby power loss in always-on systems |
| TJ max | 150 °C - extended junction temperature rating; qualified for under-hood automotive environments |

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-10BQ090-M3/45 | Single-die 10A/90V Schottky; VF = 0.82V @ 5A, RθJC = 3.5°C/W; no AEC-Q101 qualification | Not approved for automotive under-hood use; suitable for commercial-industrial SMPS only | Choose when AEC-Q101 is not required and lower VF is prioritized over thermal performance |
| ON Semiconductor SB1090 | Single-anode, single-cathode TO-220AB; VF = 0.87V @ 5A; AEC-Q101 qualified; no dual-die configuration | Lacks dual-anode flexibility for center-tapped or interleaved designs; requires two devices for same functionality | Choose when board space allows discrete placement and dual-anode integration is unnecessary |
Compared with VS-10BQ090-M3/45 and SB1090, SR1090HC0G uniquely combines AEC-Q101 qualification, dual-anode topology, and 3°C/W thermal resistance - making it the only option supporting automotive-grade 10A rectification in single TO-220AB footprint with center-tap capability.

FAQ
What is the maximum junction temperature rating for SR1090HC0G?
The SR1090HC0G has a maximum junction temperature (TJ max) of +150°C, verified per AEC-Q101 stress testing. This rating enables operation in under-hood automotive environments where ambient temperatures exceed 105°C, provided thermal design maintains junction temperature below this limit using the specified 3°C/W RθJC path.
Is SR1090HC0G pin-compatible with standard TO-220AB Schottky rectifiers?
Yes, SR1090HC0G uses industry-standard TO-220AB mechanical dimensions and lead spacing. However, its dual-anode pinout differs from single-anode TO-220AB rectifiers - Lead 1 and Lead 3 are anodes, Lead 2 is the common cathode. PCB layout must accommodate this 3-terminal dual-anode configuration.
Does SR1090HC0G meet halogen-free and RoHS requirements?
Yes, SR1090HC0G complies with both RoHS Directive 2011/65/EU and halogen-free standards per IEC 61249-2-21. The molding compound contains no brominated flame retardants, and terminal plating uses matte tin - fully documented in TSC's material declaration reports.
What is the reverse leakage current specification for SR1090HC0G at 90V?
At 90V reverse voltage and 25°C junction temperature, SR1090HC0G specifies a maximum reverse current (IR) of 100 µA. At 100°C, IR rises to ≤10 mA, and at 125°C, it remains ≤2 mA - values confirmed in the official L2104 datasheet's Electrical Specifications table.
How does the guard ring structure in SR1090HC0G improve reliability?
The guard ring in SR1090HC0G enhances edge termination stability, enabling a critical dv/dt rating of 10,000 V/μs. This prevents premature avalanche breakdown during fast voltage transients in high-frequency switching converters - a key reliability factor validated in AEC-Q101 transient stress testing.
