Product details
Overview
MBR20200CT from Diodes Incorporated is a 20A dual common-cathode Schottky barrier rectifier in TO220AB (Type C) package, rated for 200V peak reverse voltage, 0.89V max forward voltage at 10A/25°C, and 0.1mA max leakage current at 200V/25°C; used for polarity protection and recirculating diode functions in DC power supplies and motor drive circuits.
For engineers reviewing the MBR20200CT datasheet, MBR20200CT pinout, MBR20200CT application, or MBR20200CT equivalent, key selection criteria include per-leg 10A average forward current rating, thermal resistance of 3°C/W (junction-to-case), low VF advantage over PN rectifiers, and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This dual-diode Schottky rectifier integrates two independent 200V/10A legs sharing a common cathode terminal, enabling synchronous half-wave rectification or bidirectional clamp configurations. Its guard ring die construction provides transient voltage suppression capability without external TVS components.
Designed for high-efficiency switching power conversion, it operates across -55°C to +175°C junction temperature range with 170A non-repetitive surge rating and exhibits stable VF drift (0.75V typ at 10A/125°C), supporting thermally demanding industrial and automotive under-hood applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - Maximum repetitive reverse blocking voltage per leg; defines safe operating limit in DC bus or flyback clamp circuits |
| IO (per leg) | 10 A - Continuous average forward current per diode leg; total device rating is 20A with shared cathode |
| VF (max) | 0.89 V @ 10A/25°C - Low conduction loss enables >95% efficiency in 12–48V SMPS outputs |
| IR (max) | 0.1 mA @ 200V/25°C - Minimal leakage preserves battery hold-up time in backup power systems |
| RθJC | 3 °C/W - Enables direct heatsink mounting for 10A continuous operation without forced air cooling |
| IFSM | 170 A - Withstands inrush surges during hot-plug or motor startup without degradation |
| AEC-Q101 | Qualified - Meets automotive reliability standards for under-hood and body electronics deployment |
Pinout & Package
TO220AB (Type C) package with 3-terminal configuration: Pin 1 (Anode 1), Pin 2 (Cathode – common), Pin 3 (Anode 2). Molded plastic case meets UL 94V-0 flammability rating; matte tin-plated copper leadframe ensures solderability per MIL-STD-202.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode of Leg 1 | Connects to input/high-side node of first rectification path; electrically isolated from Pin 3 |
| Pin 2 | Common Cathode | Shared output node for both diode legs; must be routed with low-inductance trace to minimize switching noise |
| Pin 3 | Anode of Leg 2 | Connects to input/high-side node of second rectification path; independent conduction from Pin 1 |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring die construction | Provides intrinsic transient voltage immunity up to 100V/µs dV/dt without external snubbers |
| Low VF at high temperature | 0.75V typ @ 10A/125°C - maintains efficiency in thermally constrained enclosures |
| Lead-free & halogen-free | RoHS 2 compliant with <900ppm Br/Cl and <1000ppm Sb - satisfies IPC-1752a environmental reporting |
| High surge current rating | 170A IFSM - supports 10× nominal current for 8.3ms, covering motor stall and capacitor charging events |
Applications

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-20CPH02 | Same 200V/20A dual common-cathode rating but TO247 package; RθJC = 2.5°C/W; VF = 0.87V @ 10A | Higher thermal performance suits higher ambient (>85°C) environments; larger footprint requires layout revision | Select when junction temperature margin is critical and board space permits TO247 mounting |
| ON Semiconductor MUR2020CT | Ultrafast PN rectifier (not Schottky); 200V/20A; VF = 1.15V @ 10A; IR = 5µA @ 200V; no AEC-Q101 qualification | Lower leakage benefits ultra-low-power standby; higher VF increases conduction loss and thermal load | Select only for cost-sensitive non-automotive applications where leakage dominates over efficiency |
Compared with VS-20CPH02 and MUR2020CT, MBR20200CT delivers optimal balance of low VF, AEC-Q101 compliance, and TO220AB mechanical compatibility-making it preferred for automotive body control modules and industrial power supplies where thermal, reliability, and footprint constraints intersect.

FAQ
What is the maximum junction temperature rating for MBR20200CT?
The MBR20200CT has an operating junction temperature range of -55°C to +175°C. This wide range supports deployment in under-hood automotive environments and sealed industrial enclosures without derating up to 125°C ambient, provided thermal resistance to heatsink remains ≤3°C/W.
Can MBR20200CT be used in parallel configurations?
Parallel operation is not recommended due to mismatch in forward voltage characteristics between individual legs and units. The device is designed as a monolithic dual-diode with matched thermal coupling; for higher current, use a single higher-rated part like MBR30200CT instead of paralleling.
Is MBR20200CT suitable for high-frequency switching above 100 kHz?
Yes-its Schottky architecture provides near-zero reverse recovery time (trr < 10 ns), making it suitable for hard-switched topologies up to 500 kHz. However, layout parasitics dominate at >200 kHz; keep anode traces short and symmetric to avoid imbalance between legs.
Does the TO220AB package require insulating hardware when mounted to a heatsink?
No-the TO220AB (Type C) package has an electrically isolated tab; the collector (cathode) is connected to Pin 2 only. Mounting directly to a grounded heatsink is safe and improves thermal performance. Verify isolation with multimeter before assembly if reusing legacy heatsink hardware.
