Product details
Overview
MBRS25150CTH from Taiwan Semiconductor is a 25A dual-die Schottky barrier rectifier in TO-263AB (D2PAK) package, rated for 150V repetitive peak reverse voltage (VRRM), 200A surge current (IFSM), and maximum junction temperature of 150°C. It serves as a high-efficiency freewheeling or reverse-battery protection diode in automotive DC/DC converters and low-voltage inverters.
For engineers reviewing the MBRS25150CTH datasheet, MBRS25150CTH pinout, MBRS25150CTH application, or MBRS25150CTH equivalent, key selection criteria include its 150V VRRM rating, 1.02V forward voltage at 25A/25°C, 5µA reverse leakage at 150V/125°C, AEC-Q101 qualification, and TO-263AB thermal performance with RθJC = 1°C/W.
Technical Context
This dual-die Schottky rectifier integrates two independent anode-cathode junctions in a single TO-263AB surface-mount package, enabling common-cathode configuration for synchronous rectification or dual-path freewheeling. Its guard ring structure provides overvoltage protection, and the matte tin-plated leads meet J-STD-002 solderability requirements.
Designed for high-frequency switching applications up to 20kHz, the MBRS25150CTH delivers low conduction loss with VF = 0.98V at 25A/125°C and supports rapid dv/dt transients up to 10,000 V/μs. Its moisture sensitivity level is J-STD-020 Level 1, eliminating bake requirements prior to reflow.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 150 V - Maximum repetitive reverse blocking voltage per diode; defines safe operating range in 12–48V automotive systems with transient spikes. |
| IF | 25 A - Continuous forward current per diode at TC = 110°C; enables compact thermal design in high-current DC/DC stages. |
| IFSM | 200 A - Non-repetitive surge current (8.3ms half-sine); withstands load dump and inductive kick events without failure. |
| VF @ 25A, 25°C | 1.02 V - Forward voltage drop per diode; directly determines conduction loss (25.5W total for both diodes at full load). |
| IR @ 150V, 125°C | 5 µA - Reverse leakage current per diode; ensures minimal standby power loss in battery-sensitive applications like car lighting. |
| RθJC | 1 °C/W - Junction-to-case thermal resistance; allows direct heatsinking to PCB copper or external metal slug for reliable 25A operation. |
| AEC-Q101 | Qualified - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per stress test conditions. |
Pinout & Package
Package: TO-263AB (D2PAK), 3-terminal surface-mount outline with exposed thermal pad (cathode-connected tab). Dimensions comply with JEDEC MO-263 standard; recommended pad layout includes thermal vias under the tab for optimal heat transfer.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Left) | Anode 1 | Input terminal for first Schottky diode; connects to switched node in half-bridge or buck converter topology. |
| Pin 2 (Center) | Cathode (Common) | Shared cathode connection for both diodes; electrically tied to exposed thermal tab and must be routed to ground or low-impedance return path. |
| Pin 3 (Right) | Anode 2 | Input terminal for second Schottky diode; enables dual-path operation such as interleaved freewheeling or dual-rail reverse protection. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive under-hood environments including 1000-cycle temperature cycling (-40°C to +150°C) and 1000-hour HTRB at 150°C. |
| Guard ring overvoltage protection | Prevents edge breakdown during fast transients, improving robustness against ISO 7637-2 pulse 5a/b load dump events. |
| Low VF at high temperature | 0.98V @ 25A/125°C enables stable efficiency in thermally constrained engine-control modules without derating. |
| J-STD-020 Level 1 MSL | Zero floor life limitation; can be stored indefinitely at ambient conditions and placed directly into reflow without baking. |
| Dual-die common-cathode configuration | Reduces component count vs. discrete diodes; simplifies PCB layout for bidirectional current paths in regenerative braking circuits. |

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-25CPH15 | Same 25A/150V rating, TO-247AC package; higher RθJC (1.5°C/W) and no AEC-Q101 qualification. | Requires larger heatsink area; not approved for automotive safety-critical modules. | Select when cost or legacy TO-247 footprint is prioritized over automotive qualification and thermal efficiency. |
| ON Semiconductor MBR25150CT | Identical electrical specs and TO-263AB package; differs in marking code and internal die process (no AEC-Q101 stated in datasheet Rev. 12). | Acceptable for industrial DC/DC but lacks documented automotive stress-test validation. | Choose for non-automotive designs where AEC-Q101 is not mandated and supply chain diversification is needed. |
Compared with VS-25CPH15 and MBR25150CT, the MBRS25150CTH offers superior thermal performance (RθJC = 1°C/W), guaranteed AEC-Q101 compliance, and optimized low-leakage behavior at elevated temperature-making it the preferred choice for thermally dense, safety-conscious automotive power stages.

FAQ
What is the maximum junction temperature rating for MBRS25150CTH?
The MBRS25150CTH has a maximum junction temperature (TJ MAX) of +150°C, verified per AEC-Q101 stress testing protocols. This rating enables continuous 25A operation at case temperatures up to 110°C when mounted on a properly designed PCB with thermal vias under the cathode tab. The device must be operated within this limit to maintain reliability and avoid parametric drift.
Is MBRS25150CTH pin-compatible with other parts in the MBRS25xCTH family?
Yes, all MBRS25xCTH variants-including MBRS2535CTH through MBRS25150CTH-share identical TO-263AB (D2PAK) package dimensions, pinout (Anode1–Cathode–Anode2), and thermal pad layout. This allows direct substitution across voltage grades without PCB redesign, provided system-level voltage and thermal margins are validated for the selected VRRM grade.
Does MBRS25150CTH support automated SMT placement?
Yes, MBRS25150CTH is explicitly designed for automated placement per its mechanical data: matte tin-plated leads meet J-STD-002 solderability requirements, and its TO-263AB outline conforms to IPC-7351B density level A. The device's 1.37g weight and symmetrical lead geometry ensure stable pick-and-place yield at speeds exceeding 40,000 cph.
What is the reverse leakage current specification for MBRS25150CTH at elevated temperature?
At rated 150V reverse voltage and TJ = 125°C, the MBRS25150CTH exhibits a maximum reverse leakage current (IR) of 5 µA per diode. This low leakage is critical for minimizing standby power loss in always-on automotive modules such as telematics control units and body control modules powered from the vehicle battery.
How does the guard ring feature improve reliability in MBRS25150CTH?
The guard ring in MBRS25150CTH mitigates edge breakdown during high dv/dt transients by redistributing electric field concentration away from the silicon periphery. This design enhancement increases immunity to ISO 7637-2 load dump pulses and improves long-term reliability in automotive environments where voltage spikes up to 120V occur repeatedly over the vehicle lifetime.
