Product details
Overview
MBRD20100CT-13 from Diodes Incorporated is a 20A dual common-cathode Schottky barrier rectifier in TO252 (DPAK) package, rated for 100V reverse voltage, with max 0.84V forward voltage at 10A/25°C and 0.1mA leakage at 100V/25°C; used as polarity protection and recirculating diode in DC-DC converters and motor drive power stages.
For engineers reviewing the MBRD20100CT-13 datasheet, MBRD20100CT-13 pinout, MBRD20100CT-13 application, or MBRD20100CT-13 equivalent, key selection criteria include per-leg 10A average current rating, 150A non-repetitive surge capability, thermal resistance of 6°C/W junction-to-case, RoHS-compliant matte tin finish, and TO252 footprint compatibility with high-power PCB layouts.
Technical Context
This dual Schottky rectifier integrates two independent 10A legs sharing a common cathode terminal, enabling synchronous half-bridge freewheeling or dual-rail polarity protection. Its guard ring die construction provides transient immunity, while low VF minimizes conduction loss in high-frequency switching applications up to 100kHz.
Designed for surface-mount operation on 2-inch aluminum boards, it delivers 20A total average output current with thermal derating above 25°C ambient-maintaining 10A per leg up to 100°C ambient per Figure 4-and supports capacitance-loaded circuits with 20% current derating.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Maximum repetitive reverse blocking voltage per leg; defines safe operating range in DC bus clamp or flyback snubber circuits. |
| IO (per leg) | 10 A - Continuous average forward current per anode leg at TA = +25°C; determines heatsink sizing for sustained load conditions. |
| VF (max) | 0.84 V @ 10A, +25°C - Peak forward voltage drop; directly impacts power loss (P = IO × VF) and thermal rise in high-current paths. |
| IFSM | 150 A - Non-repetitive 8.3ms surge current rating; enables robust handling of motor startup or capacitor inrush transients. |
| RθJC | 6 °C/W - Junction-to-case thermal resistance; allows direct calculation of junction temperature rise when mounted to copper plane or heatsink. |
| IR (max) | 0.1 mA @ 100V, +25°C - Max reverse leakage per leg; critical for low-power standby modes and battery-backed systems. |
Pinout & Package
Package: TO252 (DPAK), surface-mount, single-row 3-terminal outline with exposed cathode pad for thermal conduction. Dimensions per AP02002: D = 6.10 mm, E = 6.58 mm, H = 9.91 mm, L = 1.59 mm, b3 = 5.33 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode 1 (Pin 1) | Input terminal for first rectifier leg | Accepts positive input from DC source or switching node; electrically isolated from Anode 2. |
| Cathode (Pin 2) | Common cathode connection | Shared output node for both legs; soldered to large copper pour for thermal dissipation and low-inductance return path. |
| Anode 2 (Pin 3) | Input terminal for second rectifier leg | Independent input for dual-rail or redundant path; enables split-bus or dual-phase freewheeling configurations. |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring die construction | Enhances ESD and transient voltage immunity without external TVS, reducing BOM count in industrial power supplies. |
| Low VF (0.72–0.84 V) | Reduces conduction loss by ≥30% vs. standard PN rectifiers at 10A, improving efficiency in 12V/24V DC-DC stages. |
| TO252 thermal performance | 6°C/W RθJC enables 20A operation with minimal heatsinking when mounted on ≥1 sq-in 2oz Cu board. |
| RoHS & Halogen-free | Meets EU Directive 2011/65/EU and contains <900ppm Br/Cl, <1000ppm Sb-compliant for automotive and medical end equipment. |
Applications
| DC-DC Converter Freewheeling | Motor Drive Polarity Protection |
|---|---|
Use Scenario: Used in synchronous buck converter output stage to recirculate inductor current during low-side switch off-time. IC Role / Device Role / Timing Role: Dual-leg Schottky rectifier providing low-loss bidirectional current path with fast recovery (<50ns). Use Value: Enables >92% efficiency at 10A/12V output by minimizing VF-related losses versus PN alternatives. | Use Scenario: Installed across H-bridge inputs to prevent reverse polarity damage during battery swap or wiring error. IC Role / Device Role / Timing Role: Common-cathode dual diode clamping positive rail to ground and negative rail to ground simultaneously. Use Value: Withstands 150A surge without failure, protecting MOSFET bridges from accidental -12V/24V reverse connection. |
| Solar Charge Controller Clamp | Industrial Power Supply OR-ing |
Use Scenario: Placed between PV panel and MPPT controller to block reverse current at night or under shading. IC Role / Device Role / Timing Role: Reverse-blocking diode preventing battery discharge through panel string during low-light conditions. Use Value: 0.1mA IR at 100V ensures <10µA nightly leakage per panel-critical for off-grid system autonomy. | Use Scenario: Employed in redundant 24V power supply modules to isolate failed units and maintain system uptime. IC Role / Device Role / Timing Role: Dual-anode configuration allows independent OR-ing of two input rails into shared load bus. Use Value: Low VF ensures <0.5W conduction loss per leg at 10A, minimizing heat buildup in enclosed 19″ rack environments. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay V20100C-E3/45 | Same TO252 package, 100V/10A per leg, VF = 0.82V @ 10A but RθJC = 7.5°C/W | Higher thermal resistance requires larger copper area for equivalent 20A operation | Select when legacy Vishay sourcing is mandated; verify thermal layout against 1.5× RθJC penalty. |
| ON Semiconductor MBR20100CT | Identical electrical specs and TO252 footprint; IR = 0.2mA @ 100V/25°C (vs. 0.1mA) | Slightly higher leakage may impact ultra-low-power standby in battery systems | Drop-in replacement where 0.1mA leakage is not required; validated for industrial motor drives. |
Compared with V20100C-E3/45 and MBR20100CT, MBRD20100CT-13 offers the lowest RθJC (6°C/W) and tightest IR spec (0.1mA), making it optimal for thermally constrained or low-leakage applications like solar charge controllers and medical power supplies.

FAQ
What is the maximum junction temperature for MBRD20100CT-13?
The device has an operating junction temperature range of –55°C to +175°C. At 10A per leg and 25°C ambient, junction temperature rise is approximately 60°C (10A² × RθJC × 6°C/W), well within limit. Derating begins above 25°C ambient per Figure 4.
Is MBRD20100CT-13 suitable for automotive applications?
It meets AEC-Q101 stress test requirements for discrete diodes and is RoHS/halogen-free, but is not officially qualified to AEC-Q101. For automotive use, Diodes recommends the AEC-Q101-qualified MBRD20100CTQ variant with identical electrical specs and enhanced reliability screening.
How does the common-cathode configuration affect PCB layout?
The shared cathode (Pin 2) must connect to a large, low-impedance copper pour for thermal and electrical performance. Anode pins (1 and 3) require separate traces routed to their respective input nodes; minimum spacing of 0.5mm between anodes prevents creepage in 100V applications.
Can MBRD20100CT-13 replace a single 20A Schottky in TO220?
No-it is a dual 10A device with common cathode, not a single 20A unit. Replacing a TO220 20A Schottky requires verifying per-leg current distribution, thermal path (TO252 has lower RθJC than TO220 but smaller copper interface), and mechanical mounting constraints.
