Product details
Overview
MBR10150CT-G1 from Diodes Incorporated is a 10A dual common-cathode Schottky barrier rectifier in TO-220AB package, rated for 150V peak reverse voltage, with max 0.89V forward voltage at 5A/25°C and 0.05mA leakage at 150V/25°C; used for polarity protection and recirculating diode functions in DC power supplies and motor drive circuits.
For engineers reviewing the MBR10150CT-G1 datasheet, MBR10150CT-G1 pinout, MBR10150CT-G1 application, or MBR10150CT-G1 equivalent, key selection criteria include per-leg 5A average current rating, thermal resistance of 4°C/W (junction-to-case), low VF for reduced conduction loss, guard ring construction for transient robustness, and RoHS-compliant matte tin finish on copper leadframe.
Technical Context
This dual-diode Schottky rectifier integrates two independent 5A legs sharing a common cathode terminal, enabling synchronous half-wave rectification or bidirectional clamping. Its guard ring die structure enhances ESD and surge immunity without external TVS components.
Designed for operation up to +175°C junction temperature, it delivers stable performance under high ambient conditions when mounted on a heatsink (45mm × 20mm × 12mm), with thermal resistance optimized for TO-220AB mechanical mounting and solder thermal path integrity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 150 V - Maximum repetitive reverse blocking voltage per leg; defines safe operating limit in DC bus or flyback clamp applications. |
| IO (per leg) | 5 A - Continuous average forward current per diode leg; determines usable output capacity in dual-path designs. |
| VF (max) | 0.89 V @ 5A, 25°C - Low conduction loss enables >92% efficiency in 12V–48V SMPS outputs. |
| IR (max) | 0.05 mA @ 150V, 25°C - Minimal leakage preserves battery hold-up time in always-on systems. |
| RθJC | 4 °C/W - Junction-to-case thermal resistance supports 10W dissipation with ≤40°C case-to-ambient delta under heatsink mounting. |
| Surge Current | 100 A @ 8.3ms - Withstands inrush and motor commutation spikes without degradation. |
| Operating Temp | −55°C to +175°C - Enables deployment in under-hood automotive or industrial motor control enclosures. |
Pinout & Package
TO-220AB 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; terminals feature matte tin annealed over copper leadframe for reliable solder wetting.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode of Leg 1 | Input node for first rectification path; connects to AC input or switching node in half-bridge topology. |
| Pin 2 | Common Cathode | Shared output node; ties both legs to positive rail or ground return in dual-supply configurations. |
| Pin 3 | Anode of Leg 2 | Input node for second rectification path; enables independent control or redundancy in fault-tolerant designs. |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring die construction | Improves transient voltage immunity (IEC 61000-4-5) without requiring external snubbers in 24V industrial controls. |
| High surge current capability (100A) | Supports repeated motor startup events in BLDC drivers without parameter drift or bond wire failure. |
| Low forward voltage (0.89V max) | Reduces power loss by ≥1.2W vs. standard silicon rectifiers at 5A, lowering heatsink requirements. |
| RoHS-compliant, halogen-free | Meets IPC-1752A material declaration standards for automotive Tier-1 BOM compliance and WEEE recycling. |
Applications
| DC Power Supply Input Stage | Motor Drive Freewheeling |
|---|---|
Use Scenario: AC/DC front-end rectification in 24V industrial power supplies with dual-rail outputs. IC Role / Device Role / Timing Role: Dual-leg Schottky rectifier providing isolated +24V and −24V rails via center-tapped transformer. Use Value: Common-cathode architecture simplifies PCB layout and reduces component count versus discrete diode pairs. | Use Scenario: Bidirectional energy recirculation in H-bridge motor controllers driving 12V brushed DC motors. IC Role / Device Role / Timing Role: Freewheeling diode pair clamping inductive kickback during PWM turn-off transitions. Use Value: 100A surge rating absorbs repetitive 50A motor stall currents without derating or thermal shutdown. |
| Polarity Protection Circuit | Battery Backup Clamping |
Use Scenario: Reverse-voltage protection in 48V telecom power distribution units with hot-swap capability. IC Role / Device Role / Timing Role: Series-connected anode-leg diode blocking reverse current while minimizing insertion loss. Use Value: 0.89V VF limits voltage drop to <2% at full load, preserving system brown-out margin. | Use Scenario: Supercapacitor backup circuit in smart metering modules requiring seamless switchover.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MBR10150C | Same electrical specs; updated marking and packaging per Diodes' obsolescence replacement program. | Drop-in replacement with identical thermal and footprint compatibility; no design change required. | Select for new designs to ensure long-term supply continuity and avoid obsolete part risk. |
| STPS10H150CG | 10A total / 5A per leg, 150V VRRM, VF = 0.87V @ 5A, RθJC = 4.5°C/W; TO-220AC package (single anode variant). | Lacks common-cathode configuration; requires two devices for dual-leg function, increasing board area and BOM cost. | Use only if redesign permits discrete placement and thermal management allows higher RθJC. |
Compared with MBR10150CT-G1, MBR10150C offers identical performance with assured availability, while STPS10H150CG requires layout revision and yields 12% higher conduction loss per leg due to non-common-cathode routing inefficiency.

FAQ
Is MBR10150CT-G1 still in active production?
No - Diodes Incorporated has discontinued MBR10150CT-G1 and designated it obsolete. The recommended replacement is MBR10150C, which maintains identical electrical and mechanical specifications with updated packaging and traceability. Aetrix Electronics holds limited legacy stock for repair and maintenance use only.
What is the maximum continuous current per leg at 100°C ambient?
At TA = 100°C with proper heatsinking (45mm × 20mm × 12mm), the derated average forward current per leg is 3.2A, based on the forward current derating curve (Figure 4) and RθJA = 15°C/W. This ensures TJ remains ≤175°C under steady-state operation.
Can MBR10150CT-G1 be used in automotive applications?
MBR10150CT-G1 is not AEC-Q200 qualified and lacks PPAP documentation. For automotive use, Diodes recommends the Q-suffix variant (e.g., MBR10150CTQ) - manufactured in IATF 16949-certified facilities and tested to AEC-Q200 stress requirements for passive components.
Does this device require a heatsink in 5A continuous operation?
Yes - at 5A per leg and TA = 25°C, power dissipation reaches ~4.5W. Without a heatsink, junction temperature would exceed 175°C due to RθJA = 15°C/W. A minimum 45mm × 20mm × 12mm heatsink is required to maintain safe thermal operation per datasheet Figure 4.
