Product details

Overview

MBR1050CT from Diodes Incorporated is a 10A dual common-cathode Schottky barrier rectifier in TO-220AB package, rated for 50V peak repetitive reverse voltage, with maximum forward voltage drop of 0.65V at 5A and 25°C, leakage current ≤0.1mA at rated DC blocking voltage, and thermal resistance of 3 K/W junction-to-case - used in DC power input polarity protection and flyback energy recirculation in industrial power supplies.

For engineers reviewing the MBR1050CT datasheet, MBR1050CT pinout, MBR1050CT application, or MBR1050CT equivalent, key selection criteria include per-leg 5A average rectified current capability, low VF performance up to +125°C, AEC-Q101 qualification for reliability-critical environments, and TO-220AB mechanical compatibility with standard heatsink mounting.

Technical Context

This dual-element Schottky rectifier integrates two independent anode terminals (Pin 1 and Pin 3) sharing a common cathode (Pin 2), enabling synchronous half-wave rectification or independent leg operation in dual-rail or redundancy configurations. Its guard ring die construction enhances transient surge immunity, while the low V_F minimizes conduction losses in high-frequency switching applications.

Rated for continuous operation from –55°C to +150°C, it supports 100A non-repetitive peak forward surge current (8.3ms half-sine), and exhibits typical junction-to-case thermal resistance of 3 K/W when mounted on a 45mm × 20mm × 12mm heatsink - critical for thermal management in compact 12V/24V DC-DC front-end designs.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	50 V - Maximum peak repetitive reverse voltage per leg; defines safe DC blocking margin in 36V nominal systems.
I_O (per leg)	5 A - Average rectified output current per anode-cathode path at +25°C case temperature; total device rating is 10A.
V_F max @ 5A, 25°C	0.65 V - Forward voltage drop limiting conduction loss to ≤3.25W per leg at full load.
I_R max @ 25°C	0.1 mA - Reverse leakage current at rated DC blocking voltage; ensures minimal standby power loss.
R_θJC	3 K/W - Junction-to-case thermal resistance; enables direct heatsink attachment without thermal interface material for <10W dissipation.
I_FSM	100 A - Non-repetitive surge current handling; sustains brief inrush or fault currents in unregulated inputs.
C_T typ	150 pF - Total capacitance per element at 1 MHz and 4V reverse bias; limits high-frequency noise coupling in EMI-sensitive circuits.

Pinout & Package

Package: TO-220AB - molded plastic case with matte tin–annealed copper leadframe, UL 94V-0 flammability rating, moisture sensitivity level 1, and 1.95g mass. Mounting tab (case) is electrically connected to Pin 2 (cathode).

Pin/Terminal	Circuit Role	Design Meaning
Pin 1	Anode 1	Independent input terminal for first rectifying leg; accepts AC or switched DC input.
Pin 2	Common Cathode	Shared output node for both legs; electrically tied to metal tab for thermal and electrical grounding.
Pin 3	Anode 2	Independent input terminal for second rectifying leg; enables dual-path or redundant rectification.

Key Features

Feature	Design Value
Guard ring die construction	Improves ESD and transient voltage immunity without external TVS, supporting IEC 61000-4-5 surge robustness.
AEC-Q101 qualification	Validated for automotive-grade reliability including temperature cycling, HTRB, and UHAST - suitable for under-hood power modules.
Lead-free & halogen-free	Meets RoHS 2 and JEDEC J-STD-020 Level 1; eliminates bromine (<900 ppm), chlorine (<900 ppm), and antimony (<1000 ppm).
Low thermal resistance	3 K/W R_θJC allows direct heatsink mounting - reduces need for thermal pads or paste in space-constrained 1U power supplies.

Applications

DC Power Input Polarity Protection

Flyback Energy Recirculation

Use Scenario: Prevents damage from reversed battery or adapter connection in 12V/24V industrial controllers.

IC Role / Device Role / Timing Role: Dual-anode Schottky diode configured as OR-ing element with common cathode output to system rail.

Use Value: Enables zero-loss reverse-blocking with <0.65V forward drop, reducing heat generation versus MOSFET-based solutions.

Use Scenario: Freewheeling path for inductive loads in relay drivers and solenoid control circuits.

IC Role / Device Role / Timing Role: Fast-recovery recirculation diode across coil windings during switch-off transitions.

Use Value: 150pF capacitance and sub-ns recovery minimize voltage overshoot and EMI emissions during turn-off.

Dual-Rail DC-DC Front-End

Redundant Power Supply Input

Use Scenario: Independent rectification of two isolated AC/DC outputs feeding separate 5V and 3.3V LDO inputs.

IC Role / Device Role / Timing Role: Two discrete Schottky paths sharing one cathode output node to reduce component count.

Use Value: Dual-leg integration saves PCB area versus two discrete TO-220 devices while maintaining thermal isolation.

Use Scenario: N+1 redundant 48V telecom rectifier modules where failure of one input must not disrupt output.

IC Role / Device Role / Timing Role: Common-cathode configuration enables automatic current sharing between parallel inputs via forward-drop matching.

Use Value: Matched V_F characteristics (±5% typical) ensure balanced load distribution without external balancing resistors.

Equivalent & Alternatives

The following parts are listed as comparable options for similar Schottky rectifier applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STPS10H100CG	100V V_RRM, same TO-220AB package, 0.78V V_F max @ 5A, 0.5mA I_R - higher voltage rating but higher conduction loss.	Preferred in 48V bus systems requiring >60V margin; less suitable for 12V/24V where low V_F dominates efficiency.	Select when system V_R exceeds 55V; verify thermal derating due to higher V_F.
VBSE1050-M3/45	50V V_RRM, TO-220AC package (isolated tab), 0.62V V_F max @ 5A, 0.15mA I_R - electrically identical but electrically isolated case.	Required where cathode must be floating from chassis ground; adds isolation but increases cost and thermal resistance.	Choose only when galvanic isolation of the cathode is mandatory; otherwise MBR1050CT offers lower R_θJC.

Compared with STPS10H100CG and VBSE1050-M3/45, MBR1050CT delivers optimal balance of low forward voltage, tight leakage control, and AEC-Q101 qualification in a thermally efficient, cost-effective TO-220AB package - making it preferred for 12V–36V industrial and automotive power interfaces where thermal density and reliability are prioritized.

FAQ

Is MBR1050CT pin-compatible with MBR1040CT or MBR1060CT-I?

Yes - all three share identical TO-220AB pinout (Anode1–Cathode–Anode2), same mechanical footprint, and common cathode topology. Voltage ratings differ (40V/50V/60V), so substitution requires verification of reverse voltage margin in the target circuit.

What is the maximum continuous case temperature for MBR1050CT at full 5A per leg?

The device supports continuous operation up to +150°C case temperature. At 5A per leg and 25°C ambient, thermal design must limit T_C to ≤125°C to maintain V_F and I_R within datasheet limits - achievable with a 45mm × 20mm × 12mm heatsink per Diodes' recommended layout.

Does MBR1050CT require a minimum load or snubber network?

No - as a Schottky rectifier, it has no minority-carrier storage delay and does not require snubbers for typical flyback or polarity protection use. However, a small RC snubber (e.g., 100Ω + 100pF) may be added across each anode–cathode pair in high-dI/dt switching applications to suppress ringing.

Can MBR1050CT be used in surface-mount PCB assemblies?

No - it is through-hole TO-220AB packaged and requires vertical mounting with tab secured to a heatsink. Surface-mount alternatives like the DFLS1200Q (dual Schottky in SO-8) exist but differ in current rating, thermal path, and voltage capability.
