Product details
Overview
SRF1090HC0G from Taiwan Semiconductor is a 10A, 90V AEC-Q101-qualified Schottky barrier rectifier in ITO-220AB package with dual-die configuration, 4.0°C/W junction-to-case thermal resistance, 120A surge capability, and 100µA max reverse leakage at 25°C - used in automotive-grade DC-DC converters and industrial SMPS.
For engineers reviewing the SRF1090HC0G datasheet, SRF1090HC0G pinout, SRF1090HC0G application, or SRF1090HC0G equivalent, key selection criteria include its 90V VRRM, AEC-Q101 qualification, low VF (0.90V max @ 5A/25°C), thermal performance in high-power rectification, and ITO-220AB mounting compatibility.
Technical Context
This device implements a dual-die Schottky structure with guard ring overvoltage protection and matte tin-plated leads compliant with J-STD-002 solderability. It operates across -55°C to +150°C junction temperature range and meets UL 94V-0 flammability rating.
Designed for high-efficiency rectification, it delivers low forward voltage drop and high surge current tolerance (120A, 8.3ms half-sine), enabling compact thermal design in space-constrained power stages where reliability under transient stress is critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 90 V - maximum repetitive reverse voltage; defines safe blocking capability in 48V–72V bus applications |
| IF | 10 A - continuous forward current; supports steady-state output rectification in 100–200W SMPS |
| IFSM | 120 A - non-repetitive surge current; withstands inrush and fault transients without failure |
| VF (max) | 0.90 V @ 5A, 25°C - low conduction loss enables >92% efficiency in 12V-output converters |
| RθJC | 4.0 °C/W - thermal resistance from junction to case; enables direct heatsink mounting with predictable ΔT |
| IR (max) | 100 µA @ 90V, 25°C - low leakage preserves standby power budget in always-on systems |
| TJ max | +150 °C - extended junction rating supports operation in 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 | Same 90V VRRM, 10A IF, but TO-220AC package; RθJC = 3.0°C/W; no AEC-Q101 qualification | Preferred for non-automotive industrial use where lower thermal resistance justifies non-isolated package | Select when heatsinking is optimized for TO-220AC footprint and automotive qualification is unnecessary |
| ON Semiconductor MBR1090CT | Dual common-cathode Schottky in TO-220AB; 90V VRRM, 10A IF; RθJC = 3.5°C/W; no AEC-Q101 or UL recognition | Suitable for cost-sensitive consumer adapters where regulatory certifications are not required | Choose for legacy designs using TO-220AB footprint and where UL/AEC-Q101 are not mandated |
Compared with VS-10BQ090-M3/45 and MBR1090CT, the SRF1090HC0G uniquely combines AEC-Q101 qualification, UL recognition, and ITO-220AB insulation - making it the only option qualified for safety-critical automotive power conversion where creepage/clearance and long-term reliability are mandatory.

FAQ
What does the 'H' suffix in SRF1090HC0G indicate?
The 'H' in SRF1090HC0G denotes AEC-Q101 qualification - confirming that the SRF1090HC0G has passed rigorous stress testing for automotive power electronics, including high-temperature reverse bias, temperature cycling, and highly accelerated life testing. This makes the SRF1090HC0G suitable for under-hood and safety-critical applications where standard industrial-grade parts are insufficient.
Is SRF1090HC0G pin-compatible with standard TO-220AB dual-diode rectifiers?
No - the SRF1090HC0G uses the ITO-220AB package, which features an electrically isolated metal tab, unlike the conductive tab in TO-220AB. While both share the same outline dimensions and mounting hole pattern, the isolation requires different PCB layout considerations: the tab must be tied to circuit potential via insulated thermal interface, not directly grounded. This distinction affects thermal and electrical integration in the SRF1090HC0G design.
What is the maximum junction temperature rating for SRF1090HC0G?
The SRF1090HC0G has a maximum junction temperature (TJ) rating of +150°C, verified per its absolute maximum ratings table. This extended rating enables reliable operation in high-ambient environments such as automotive engine compartments or enclosed industrial enclosures, provided thermal design maintains junction temperature below this limit during peak load and transient conditions.
Does SRF1090HC0G meet halogen-free and RoHS requirements?
Yes - the SRF1090HC0G complies with RoHS Directive 2011/65/EU and is halogen-free per IEC 61249-2-21. The molding compound contains no brominated flame retardants or chlorine-based additives, and all terminations use matte tin plating. These attributes are confirmed in Taiwan Semiconductor's official compliance documentation for the SRF1090HC0G product family.
How does the guard ring feature improve SRF1090HC0G reliability?
The guard ring in the SRF1090HC0G enhances edge termination robustness by reducing electric field concentration at the silicon periphery, thereby suppressing premature avalanche breakdown under voltage transients. This structural feature directly improves the SRF1090HC0G's ability to withstand repetitive line surges and load dump events in automotive systems without degradation - a key factor in achieving AEC-Q101 qualification.
