MBRD10200CTTR 概要
A Schottky barrier rectifier is a power semiconductor that uses a metal-semiconductor junction instead of a PN junction, eliminating minority-carrier storage time. This enables fast switching transitions and low forward voltage drop, making Schottky rectifiers a preferred choice for high-frequency switch-mode power supplies, DC-DC converters, and reverse-polarity protection circuits. Within the power-semiconductor taxonomy, the MBRD10200CTTR sits at the hierarchy Schottky rectifier → rectifier diode → discrete semiconductor → power component.
Key specifications include a maximum average forward rectified current of 10 A (per device, per package), 200 V maximum reverse voltage, surge current capability, and a guard-ring die construction that absorbs transient energy. The DPAK (TO-252-3) package delivers a low thermal resistance path through the mounting tab, supporting PCB-based heatsinking without external hardware in moderate-power designs. The "TR" suffix indicates Tape & Reel packaging for high-volume SMT assembly.
The MBRD10200CTTR uses a guard-ring-protected Schottky die that combines high surge current capability with low reverse leakage. Compared with standard-recovery rectifiers, it trades higher reverse leakage (inherent to Schottky physics) for switching speeds orders of magnitude faster and forward voltage roughly 0.3-0.5 V lower. Designers must derate leakage with temperature in high-voltage sections.
Typical applications include switch-mode power supply output rectification, freewheeling diodes for motor-drive and relay coils, DC-DC converter secondary-side rectifiers, and reverse-polarity protection rails in industrial and telecom systems. The 200 V rating provides comfortable headroom for 48 V telecom buses and 100/120 V offline-derived rails.
When designing with this part, ensure the heatsink tab is soldered to a copper pour sized to keep junction temperature below 150 °C under worst-case load. Reverse leakage roughly doubles every 10 °C, so thermal management directly impacts blocking performance.

主な用途
MBRD10200CTTR の用途: 6 件s: Switch-Mode Power Supply Output Rectification, Freewheeling Diode for Motor and Relay Coils, Reverse-Polarity Protection Rail, DC-DC Converter Secondary Rectifier, Battery Charger Reverse-Blocking Diode, Industrial 48 V Telecom Rectifier.
Switch-Mode Power Supply Output Rectification
The MBRD10200CTTR functions as the secondary-side output rectifier in isolated switch-mode power supplies (SMPS) where its 200 V VRRM provides comfortable headroom for 48 V telecom rails and 100/120 V offline-derived outputs. The common-cathode dual-Schottky configuration halves the conduction footprint versus discrete diodes, while the low forward voltage drop near 0.85 V at 5 A reduces dissipation by roughly 50 percent compared with ultrafast-recovery alternatives. The TO-252-3 DPAK package enables PCB-side heatsinking through the central tab, eliminating external heatsinks at currents up to 10 A. Designers benefit from the absence of reverse-recovery charge, which removes switching losses that would otherwise limit SMPS operating frequency.

Freewheeling Diode for Motor and Relay Coils
Inductive loads such as DC motor windings, solenoid coils, and relay contacts generate back-EMF transients when switched off, which can exceed several hundred volts in milliseconds. The MBRD10200CTTR serves as a freewheeling (flyback) diode across such coils, clamping the inductive kick to one forward voltage drop and protecting the driving transistor or MOSFET. With 200 V reverse blocking and 10 A current handling, it comfortably manages the stored energy in 24 V and 48 V coil systems. The Schottky switching speed (essentially zero reverse recovery) eliminates the voltage overshoot typical of PN-junction flyback diodes, ensuring clean turn-off edges in PWM motor-drive circuits.
おすすめ
Reverse-Polarity Protection Rail
The MBRD10200CTTR placed in series with the input supply rail provides reverse-polarity protection for downstream circuitry. When installed backwards, the diode blocks current flow, protecting sensitive loads such as microcontrollers, sensors, and communication modules from damage. The 200 V VRRM offers headroom for transient suppression, and the 10 A continuous rating supports power-hungry loads including industrial controllers and telecom equipment. Forward voltage drop of approximately 0.85 V is acceptable for 24 V and 48 V systems, but designers targeting sub-3.3 V rails should consider MOSFET-based ideal-diode circuits instead. The DPAK package mounts cleanly on the input side of the PCB near the connector.
おすすめ
DC-DC Converter Secondary Rectifier
Forward, flyback, and half-bridge DC-DC converters operating from 48 V or higher input rails use the MBRD10200CTTR as the secondary-side rectifier, where its 200 V rating covers reflected primary voltages plus transformer leakage spikes. The common-cathode dual configuration enables full-wave rectification from a center-tapped secondary with a single package, reducing PCB area and BOM count. The Schottky switching characteristic eliminates the reverse-recovery losses that plague PN-junction rectifiers at high switching frequencies, enabling converters to operate above 200 kHz with reasonable efficiency. The DPAK thermal pad supports the 10 A continuous current with proper copper-pour heatsinking on the secondary side.
おすすめ
Battery Charger Reverse-Blocking Diode
In multi-source battery charger systems such as solar-plus-grid backup units, the MBRD10200CTTR isolates charging sources to prevent back-feed between charger outputs. Its 200 V rating handles transient voltages on 48 V battery stacks, while the 10 A rating supports chargers delivering up to 480 W of continuous power. The low forward voltage drop minimizes heat generation and improves overall charger efficiency. The TO-252-3 DPAK package with central heatsink tab simplifies thermal management on charger PCBs where space is constrained but dissipation is moderate. Designers should derate junction temperature to 125 °C for long-term reliability in always-on charging applications.
おすすめ
Industrial 48 V Telecom Rectifier
Telecom base stations and central-office equipment traditionally operate from -48 V DC battery plants with positive grounding, requiring rectification stages that block up to 100 V continuous plus transient spikes. The MBRD10200CTTR fits comfortably within these systems, providing 200 V reverse blocking and 10 A throughput for distribution panels and OR-ing circuits. The DPAK package enables dense layouts on backplane PCBs, while the Schottky switching speed supports high-frequency OR-ing controllers that switch between redundant feeds without audible cross-conduction. Engineers building NEBS-compliant telecom hardware value the device's wide operating temperature range and surface-mount compatibility for automated assembly lines.

主な差別化要因
- High VRRM (200 V) in compact DPAK package （vs Lower-voltage 100 V Schottky rectifiers in same package)
- Common-cathode dual-Schottky configuration （vs Single-diode Schottky rectifiers requiring two separate packages)
- Zero reverse recovery charge （vs Ultrafast PN-junction rectifiers (e.g., MUR-series))
設計ノート
Estimated: at 5 A per diode (10 A total) with 0.85 V forward drop, the MBRD10200CTTR dissipates roughly 4.25 W per diode (8.5 W total). The DPAK package thermal resistance from junction to tab is approximately 2 °C/W; with the tab soldered to 1 square inch of 2 oz copper, total junction-to-ambient resistance is roughly 30-40 °C/W. Without adequate copper, junction temperature can exceed 150 °C at full load. Always size the heatsink copper pour based on worst-case ambient temperature and continuous current. Use thermal vias under the tab to transfer heat to inner PCB layers for additional dissipation.
Solder the central tab to a copper pad of at least 50 mm² (roughly 7 mm × 7 mm) using a thermal pad pattern that matches the DPAK land geometry. Include 6-10 thermal vias (0.3 mm drill, 0.5 mm pad) under the tab to sink heat into internal copper planes. For dual-diode common-cathode configurations, route both anode traces on the top layer to minimize inductance, and place input/output capacitors close to each diode's anode terminal to reduce switching-loop area and EMI.
Do not exceed 200 V reverse voltage even during transient spikes - inductive loads can generate flyback voltages exceeding the DC rating. Add an RC snubber or TVS clamp across inductive loads if peak spike energy approaches the VRRM limit. Reverse leakage current roughly doubles every 10 °C, so a hot DPAK at 125 °C junction may leak several mA at 200 V, impacting standby power budgets. Verify the manufacturer's IFSM (surge current) rating before designing for inrush events such as cold-lamp turn-on or motor start.
