Product details
Overview
MBRF2035HC0G from Taiwan Semiconductor is a 20A, 35V AEC-Q101-qualified Schottky barrier rectifier in ITO-220AC package, featuring 0.75V max forward voltage at 20A/25°C, 150A surge capability, and guard ring over-voltage protection for automotive-grade power conversion.
For engineers reviewing the MBRF2035HC0G datasheet, MBRF2035HC0G pinout, MBRF2035HC0G application, or MBRF2035HC0G equivalent, this device serves as a high-efficiency, low-loss rectifier in space-constrained 12V–24V automotive SMPS, DC-DC converters, and industrial adapters where thermal performance (RθJC = 3°C/W) and reliability under transient surge are critical.
Technical Context
This single-die Schottky rectifier operates with a junction temperature range of –55°C to +150°C and supports repetitive peak reverse voltages up to 35V. Its low VF and high IFSM (150A, 8.3ms half-sine) enable efficient conduction and robust transient handling in high-frequency switching topologies.
The ITO-220AC package provides direct case-to-heatsink thermal path with 0.56 N·m maximum mounting torque, while matte tin-plated leads comply with J-STD-002 solderability and JESD201 Class 2 whisker resistance - essential for automotive under-hood environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Forward Current (IF) | 20 A continuous - supports high-power 12V/24V DC-DC output stages without forced air cooling |
| Peak Repetitive Reverse Voltage (VRRM) | 35 V - rated for 12V automotive systems with margin against load dump transients |
| Forward Voltage (VF) | ≤0.75 V @ 20A, 25°C - reduces conduction loss by >30% vs. standard PN rectifiers |
| Surge Current (IFSM) | 150 A @ 8.3 ms - withstands inrush and fault currents in unregulated input stages |
| Junction-to-Case Thermal Resistance | 3 °C/W - enables ≥15W power dissipation with moderate heatsinking |
| Operating Junction Temperature | –55°C to +150°C - qualified for under-hood automotive applications per AEC-Q101 |
Pinout & Package
ITO-220AC package: 3-terminal through-hole outline with isolated tab (cathode-connected), matte tin-plated leads, UL 94V-0 molding compound, and polarity marked on device body.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Lead 1) | Input current entry point | Connected to unregulated input rail; requires PCB copper pour for thermal relief |
| Cathode (Lead 2) | Output current exit point | Electrically tied to metal tab; must be isolated from chassis unless system ground referenced |
| Tab (Cathode) | Primary heat dissipation path & cathode connection | Provides low-thermal-resistance interface to heatsink; electrically active - isolation required if floating output |
Key Features

|---|---|
| AEC-Q101 qualification | Validated for automotive under-hood use including temperature cycling, humidity bias, and mechanical shock |
| Guard ring structure | Prevents premature edge breakdown at VRRM, improving reliability during voltage transients |
| UL Recognized (E-326243) | Meets safety requirements for end-equipment certification in AC/DC adapters and industrial power supplies |
| Halogen-free construction | Complies with IEC 61249-2-21 - supports RoHS-compliant manufacturing and end-of-life recycling |

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-MBR2035CT | TO-220AB package, dual common-cathode die, 0.78V VF max @ 20A | Requires dual-output or paralleled configuration; higher thermal resistance (RθJC = 4.5°C/W) | Select when dual-cathode topology or legacy TO-220AB footprint is required |
| ON Semiconductor MBR2035CT | TO-220AB, 0.76V VF, no AEC-Q101 qualification, RθJC = 4.0°C/W | Not qualified for automotive; lower surge rating (120A) | Choose for cost-sensitive industrial adapters where AEC-Q101 is not mandated |
Compared with VS-MBR2035CT and MBR2035CT, the MBRF2035HC0G delivers superior thermal performance (3°C/W vs. ≥4.0°C/W), AEC-Q101 compliance, and optimized single-die ITO-220AC packaging - making it the preferred choice for thermally constrained, automotive-qualified rectification where reliability under surge and high ambient temperature is non-negotiable.

FAQ
What is the maximum junction temperature rating for MBRF2035HC0G?
The MBRF2035HC0G has a maximum junction temperature (TJ) of +150°C and a minimum of –55°C, validated per AEC-Q101 stress testing. This rating enables operation in under-hood automotive environments and high-ambient industrial enclosures. Derating curves in the datasheet define safe operating current versus case temperature, with full 20A capability maintained up to ~80°C case temperature using the specified thermal interface.
Is MBRF2035HC0G pin-compatible with standard TO-220AB rectifiers?
No, MBRF2035HC0G uses the ITO-220AC package, which has a different lead frame geometry and isolated metal tab compared to TO-220AB. While both are 3-lead through-hole packages, the ITO-220AC tab is cathode-connected and electrically active, requiring PCB isolation if not grounded. Layout changes are necessary - do not assume drop-in replacement with TO-220AB parts like MBR2035CT.
Does MBRF2035HC0G meet halogen-free and RoHS requirements?
Yes, MBRF2035HC0G is RoHS compliant and 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 per J-STD-002. Certificate of Compliance is available upon request from Taiwan Semiconductor and authorized distributors.
What is the forward voltage specification for MBRF2035HC0G at elevated temperature?
At 20A and 125°C junction temperature, the MBRF2035HC0G exhibits a typical forward voltage of 0.65V, with no maximum limit specified - only a typical value. This represents a reduction from the 25°C max of 0.75V, reflecting the negative temperature coefficient of Schottky diodes. Designers should reference the Fig.4 Typical Forward Characteristics curve for precise VF interpolation across temperature and current.
How is the "H" suffix in MBRF2035HC0G designated in ordering code?
The "H" in MBRF2035HC0G indicates AEC-Q101 qualification, as defined in Taiwan Semiconductor's ordering nomenclature. The "C0G" suffix denotes green compound (halogen-free) and date/factory coding per marking diagram. Full part number decodes as: MBRF2035 (35V Schottky), H (AEC-Q101), C0G (green, RoHS, specific wafer lot). Tube packaging is 50 units per tube.
