Product details
Overview
MBR3050PTH from Taiwan Semiconductor is a 30A, 50V AEC-Q101-qualified Schottky barrier rectifier in TO-247AD package, featuring 0.75V typical forward voltage at 15A/25°C, 200A surge current rating, and 1.4°C/W junction-to-case thermal resistance. It serves as a high-efficiency output rectifier in automotive-grade DC-DC converters and industrial SMPS.
For engineers reviewing the MBR3050PTH datasheet, MBR3050PTH pinout, MBR3050PTH application, or MBR3050PTH equivalent, key selection criteria include its 50V repetitive peak reverse voltage, AEC-Q101 qualification status, low VF at high temperature, dual-die construction, and UL recognition under file E-326243.
Technical Context
This device implements a dual-die Schottky structure with guard ring overvoltage protection and matte tin-plated leads compliant with J-STD-002 solderability. Its 10,000 V/μs critical dV/dt rating supports fast-switching topologies.
Designed for operation from −55°C to +150°C junction temperature, it delivers stable reverse leakage ≤15 mA at 125°C and rated VR, with thermal performance validated by transient impedance curves up to 100 seconds pulse duration.

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-30CPH05 | Same 50V VRRM, 30A IF, TO-247AC package; VF = 0.72V typ @ 15A/25°C; no AEC-Q101 listing | Qualified for industrial/commercial use only; not approved for automotive under-hood deployment | Select when AEC-Q101 is not required and marginally lower VF is prioritized |

FAQ
What is the maximum junction temperature rating for MBR3050PTH?
The MBR3050PTH has a maximum junction temperature (TJ max) of +150°C, verified per AEC-Q101 stress testing. This rating allows operation in under-hood automotive environments and high-ambient industrial enclosures. Derating curves in the official datasheet define allowable forward current versus case temperature, with full 30A rating maintained up to 75°C case temperature. Thermal design must account for RθJC = 1.4°C/W and interface resistance to heatsink.
Is MBR3050PTH pin-compatible with MBR3050PT?
Yes, MBR3050PTH shares identical TO-247AD package dimensions, pinout, and terminal assignments with MBR3050PT. The "H" suffix denotes AEC-Q101 qualification and halogen-free construction, but mechanical and electrical interfaces remain fully compatible. No PCB layout changes are required when upgrading from MBR3050PT to MBR3050PTH in existing designs.
What is the typical forward voltage of MBR3050PTH at 30A and 125°C?
The MBR3050PTH exhibits a typical forward voltage of 0.73V at 30A and 125°C junction temperature, based on characterization data in the official Taiwan Semiconductor datasheet. This value reflects real-world conduction loss under high-load, elevated-temperature conditions typical in automotive DC-DC converters. At room temperature (25°C), VF rises to 0.82V under the same 30A condition.
Does MBR3050PTH have UL recognition?
Yes, MBR3050PTH carries UL Recognition under file E-326243, confirming compliance with UL 60950-1 and UL 62368-1 for component-level safety. This applies to the TO-247AD package construction, including flammability (UL 94V-0), dielectric strength, and tracking resistance. UL marking appears on the device body and is documented in Taiwan Semiconductor's certification reports.
What is the reverse leakage current specification for MBR3050PTH at 50V and 125°C?
At 50V reverse voltage and 125°C junction temperature, MBR3050PTH specifies a maximum reverse leakage current (IR) of 15 mA per diode, measured under 30ms pulse conditions. This parameter directly impacts standby power loss in always-on systems such as automotive infotainment modules. The datasheet confirms this value applies across the full MBR30xPTH family, including MBR3050PTH.
