Product details
Overview
SR2090HC0G from Taiwan Semiconductor is a 20A, 90V AEC-Q101-qualified Schottky barrier rectifier in TO-220AB package with dual-die configuration, 0.90 V forward voltage at 10 A and 25°C, 100 µA reverse leakage at rated VR and 25°C, and 200 A surge capability - used in automotive-grade DC/DC converters and industrial SMPS.
For engineers reviewing the SR2090HC0G datasheet, SR2090HC0G pinout, SR2090HC0G application, or SR2090HC0G equivalent, key selection criteria include its 90 V repetitive peak reverse voltage, 125°C maximum junction temperature (with extended 150°C option), guard ring overvoltage protection, RoHS/halogen-free compliance, and TO-220AB mechanical mounting requirements.
Technical Context
This Schottky rectifier uses dual-die construction in a single TO-220AB case to deliver high-current rectification with low conduction loss. Its 0.90 V VF at 10 A and 25°C enables high-efficiency operation in medium-voltage switching supplies, while the integrated guard ring structure enhances transient overvoltage robustness beyond standard Schottky limits.
The device supports 200 A non-repetitive surge current (8.3 ms half-sine) and exhibits 10,000 V/µs critical dv/dt rating - enabling reliable operation in fast-switching topologies. Thermal resistance RθJC is 1°C/W, allowing effective heatsink-coupled thermal management in space-constrained power stages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 90 V - Maximum repetitive reverse blocking voltage; defines usable input range in 48 V–72 V DC/DC front-ends |
| IF | 20 A - Continuous average forward current; supports 200–300 W output power with appropriate heatsinking |
| IFSM | 200 A - Peak non-repetitive surge current; withstands inrush and fault transients without failure |

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-20BQ090PbF | Same 20 A / 90 V rating, TO-220AC package (non-isolated tab), 0.88 V VF @ 10 A | Lacks AEC-Q101 qualification and guard ring; not rated for automotive under-hood use | Select when cost sensitivity outweighs automotive qualification and overvoltage robustness needs |
| ON Semiconductor MBR2090CT | 20 A / 90 V dual common-cathode Schottky, TO-220AB, 0.92 V VF @ 10 A, no AEC-Q101 | Single-die per anode; lower surge rating (150 A); no guard ring or halogen-free certification | Choose for legacy industrial designs where qualification and environmental compliance are not mandated |
Compared with VS-20BQ090PbF and MBR2090CT, SR2090HC0G uniquely combines AEC-Q101 qualification, guard ring protection, halogen-free compliance, and 200 A surge rating - making it the only option qualified for safety-critical automotive power conversion where reliability under transient stress is mandatory.

FAQ
What is the maximum junction temperature rating for SR2090HC0G?
The SR2090HC0G has a standard maximum junction temperature of 125°C, with an extended 150°C option available per specific ordering code variants. This rating enables deployment in under-hood automotive locations and high-ambient industrial enclosures where thermal headroom is constrained. The SR2090HC0G datasheet specifies derating curves confirming safe operation up to 125°C junction under defined thermal conditions.
Is SR2090HC0G pin-compatible with other SR20xx series parts?
Yes, all SR20xx parts including SR2090HC0G share identical TO-220AB mechanical footprint, pinout, and terminal assignments - enabling drop-in replacement across voltage grades (20 V to 150 V) without PCB redesign. However, electrical parameters such as VF, IR, and thermal behavior differ per voltage rating, so system validation is required after substitution.
Does SR2090HC0G require a heatsink in 20 A continuous operation?
Yes, SR2090HC0G requires a heatsink for 20 A continuous forward current due to its 0.90 V forward voltage drop, generating ~18 W of conduction loss. With RθJC = 1°C/W and typical RθCA > 10°C/W, a heatsink maintaining case temperature ≤85°C is necessary to hold junction temperature within the 125°C limit. The SR2090HC0G thermal curves confirm this requirement across ambient conditions.
What does the "H" suffix in SR2090HC0G signify?
The "H" in SR2090HC0G denotes AEC-Q101 qualification - confirming that the SR2090HC0G has passed stress testing for automotive applications including temperature cycling, humidity bias, and high-temperature operating life. The "C0G" suffix indicates halogen-free packaging per IEC 61249-2-21, distinguishing it from non-halogen-free variants like SR2090C.
Can SR2090HC0G be used in synchronous rectification topologies?
No, SR2090HC0G is a passive Schottky rectifier and cannot replace actively controlled MOSFETs in synchronous rectification circuits. It functions as a unidirectional, voltage-controlled conduction device - suitable for conventional diode-based rectification but not for gate-driven synchronous schemes requiring reverse conduction control. For synchronous designs, discrete MOSFETs or dedicated driver ICs must be used instead of SR2090HC0G.
