Product details
Overview
MBRF1090-E3/4W from Vishay General Semiconductor is a high-voltage Trench MOS Barrier Schottky (TMBS®) rectifier in TO-220AC package, rated for 90 V reverse voltage, 10 A average forward current, and 150 A non-repetitive surge. It delivers 0.65 V forward voltage at 10 A and 125 °C, enabling high-efficiency DC/DC conversion and freewheeling in compact power supplies.
For engineers reviewing the MBRF1090-E3/4W datasheet, MBRF1090-E3/4W pinout, MBRF1090-E3/4W application, or MBRF1090-E3/4W equivalent, key selection criteria include its low VF at elevated temperature, high dV/dt rating (10,000 V/μs), TJ max of 150 °C, and RoHS-compliant matte tin-plated leads suitable for lead-free reflow per J-STD-020.
Technical Context
The MBRF1090-E3/4W uses trench MOS Schottky technology to achieve lower conduction losses than planar Schottky or fast recovery diodes, with no minority-carrier storage delay-enabling true high-frequency operation up to several MHz. Its single-diode configuration and isolated heatsink-mountable TO-220AC package support direct thermal coupling to external heatsinks without electrical isolation components.
Rated for 150 °C junction temperature and 130 mJ non-repetitive avalanche energy, it withstands transient overloads common in switching-mode power supply output stages. The 2.0 °C/W junction-to-case thermal resistance ensures efficient heat transfer when mounted with ≤10 in-lbs torque on a heatsink.

IC Role / Device Role / Timing Role: High-efficiency unidirectional current path replacing fast recovery diodes to minimize conduction loss and thermal stress. Use Value: 0.65 V VF at 125 °C reduces power loss by ~1.5 W vs. legacy Schottky, lowering heatsink requirements and improving system MTBF. | Use Scenario: Freewheeling path in isolated 24 V to 5 V/15 A industrial DC/DC modules with wide ambient (-40 to +85 °C). IC Role / Device Role / Timing Role: Clamp inductive kickback during switch-off in synchronous buck or flyback topologies. Use Value: 150 A IFSM and 150 °C TJ max ensure reliable operation during motor-control-induced load dumps without derating. |
| Automotive On-Board Charger (OBC) Polarity Protection | Telecom Rectifier Module Input Stage |
Use Scenario: Reverse-polarity protection at 400 V DC input stage of bidirectional OBCs, where space-constrained layout demands minimal footprint. IC Role / Device Role / Timing Role: Series-blocking diode preventing battery damage during incorrect connection; operates continuously at partial load. Use Value: TO-220AC package enables direct bolt-down heatsinking to chassis ground, eliminating need for discrete thermal pads or clips. | Use Scenario: Input rectification in -48 V telecom rectifier shelves handling 30 A total output with forced-air cooling. IC Role / Device Role / Timing Role: Primary AC-to-DC interface diode in multi-phase bridge configurations. Use Value: 10,000 V/μs dV/dt rating prevents spurious turn-on during line transients, maintaining system uptime in noisy datacenter environments. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STPS10H100CG | Same 100 V VRRM, 10 A IF(AV), but TO-220FP package (isolated tab); VF = 0.72 V @ 10 A, 125 °C. | Higher VF increases conduction loss by ~0.07 V; requires larger heatsink for same thermal margin. | Select when electrical isolation between cathode and heatsink is mandatory; verify mounting torque compatibility. |
| ON Semiconductor MUR1090CT | Ultrafast recovery diode (not Schottky); 90 V VRRM, 10 A IF(AV), VF = 1.7 V @ 10 A, 25 °C; includes reverse recovery time (trr = 60 ns). | Higher VF and trr increase switching loss and EMI; unsuitable for >100 kHz operation without snubbers. | Choose only if cost sensitivity outweighs efficiency goals, or if avalanche ruggedness beyond 130 mJ is required. |
Compared with STPS10H100CG and MUR1090CT, the MBRF1090-E3/4W offers the lowest VF at elevated temperature and zero reverse recovery, making it optimal for high-frequency, thermally constrained SMPS designs-though its non-isolated tab requires careful grounding strategy.

FAQ
What is the maximum junction temperature rating for the MBRF1090-E3/4W?
The MBRF1090-E3/4W has a maximum junction temperature (TJ max) of +150 °C, verified per Vishay Document Number 89034. This rating allows continuous operation in high-ambient environments such as enclosed industrial power supplies or automotive under-hood applications. Derating curves in the datasheet define safe IF(AV) limits above 25 °C ambient, and thermal design must account for RθJC = 2.0 °C/W and heatsink interface resistance. The MBRF1090-E3/4W maintains stable VF performance up to this limit.
Does the MBRF1090-E3/4W have an electrically isolated heatsink tab?
No, the MBRF1090-E3/4W in TO-220AC package features a non-isolated cathode tab (Pin 2), which is electrically connected to the cathode terminal. This differs from TO-220FP or ITO-220AC variants. Circuit layout must ensure the heatsink is either floating or referenced to cathode potential. The MBRF1090-E3/4W datasheet explicitly states "Polarity: as marked" and shows Pin 2 as cathode/heatsink-no internal insulation is provided.
What is the forward voltage drop of the MBRF1090-E3/4W at 10 A and 125 °C?
The MBRF1090-E3/4W exhibits a maximum forward voltage drop (VF) of 0.65 V at 10 A and case temperature (TC) of 125 °C, per Electrical Characteristics table in Vishay Document 89034. This value is confirmed under pulsed test conditions (≤40 ms) and reflects real-world thermal performance in actively cooled systems. At 25 °C, VF is 0.80 V max-demonstrating the MBRF1090-E3/4W's superior temperature stability versus conventional Schottky diodes.
Is the MBRF1090-E3/4W suitable for high-frequency switching applications above 200 kHz?
Yes, the MBRF1090-E3/4W is optimized for high-frequency operation due to its trench MOS Schottky structure, which eliminates reverse recovery charge (Qrr ≈ 0) and associated switching losses. Its 10,000 V/μs dV/dt rating and low junction capacitance (typ. 200 pF at 5 V) enable stable performance in 300–500 kHz SMPS designs. The MBRF1090-E3/4W is explicitly recommended for "high frequency rectifier of switching mode power supplies" in Vishay's Typical Applications section.
What does the "E3/4W" suffix indicate in MBRF1090-E3/4W?
The "E3" suffix denotes RoHS-compliant, commercial-grade construction with matte tin-plated leads meeting JESD 201 Class 1A whisker testing. The "/4W" indicates packaging in tubes of 50 units, using the "4W" package code defined in Vishay's Ordering Information table. This distinguishes it from tape-and-reel variants (e.g., "/8W"). The MBRF1090-E3/4W is not a different electrical variant-the E3/4W identifies environmental compliance and delivery format only.
