Product details
Overview
MBRS25100CTH from Taiwan Semiconductor is a dual-die Schottky barrier rectifier in TO-263AB (D2PAK) package, rated for 25 A average forward current, 100 V repetitive peak reverse voltage, and 200 A non-repetitive surge current, with typical forward voltage of 0.92 V at 25 A and 25°C - used in automotive DC/DC converters and reverse battery protection circuits.
For engineers reviewing the MBRS25100CTH datasheet, MBRS25100CTH pinout, MBRS25100CTH application, or MBRS25100CTH equivalent, key selection criteria include its AEC-Q101 qualification, 1.0°C/W junction-to-case thermal resistance, low 7.5 mA reverse leakage at 125°C and rated VR, and guard-ring–enhanced overvoltage robustness in high-surge automotive environments.
Technical Context
This dual-common-cathode Schottky rectifier integrates two independent diode dies in a single surface-mount D2PAK thermally optimized for high-current, low-loss operation. Its architecture delivers fast switching with no minority-carrier recovery, enabling use in high-frequency (>20 kHz) square-wave applications without snubbers.
The device operates across –55°C to +150°C junction temperature range and features matte tin-plated leads compliant with J-STD-002 solderability, JESD201 Class 2 whisker resistance, and moisture sensitivity level 1 per J-STD-020 - confirming suitability for lead-free reflow and automotive under-hood deployment.
Key Specifications

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-25CPH10-M3 | Same TO-263AB package, 25 A/100 V rating, but VF = 0.87 V @ 25 A/25°C (lower conduction loss); no AEC-Q101 certification | Preferred for industrial DC/DC where automotive qualification is not required | Select when lower VF is prioritized and automotive qualification is unnecessary |
| ON Semiconductor MBR25100CT | Identical electrical specs and TO-263AB package; AEC-Q101 qualified; VF = 0.93 V @ 25 A/25°C - functionally aligned but different marking and traceability | Drop-in replacement in legacy designs using ON's MBR25100CT with same layout and thermal design | Choose for supply chain diversification while retaining full functional and mechanical compatibility |
Compared with VS-25CPH10-M3 and MBR25100CT, MBRS25100CTH offers AEC-Q101 validation plus tighter thermal resistance (1.0°C/W vs. 1.2°C/W typical for MBR25100CT), making it preferred for thermally constrained automotive modules where long-term reliability under cyclic thermal stress is critical.

FAQ
What is the maximum junction temperature rating for MBRS25100CTH?
The MBRS25100CTH has a maximum junction temperature (TJ max) of +150°C, validated per AEC-Q101 stress testing. This rating allows reliable operation in under-hood automotive environments where ambient temperatures exceed 105°C, provided thermal design maintains actual TJ below this limit using the specified 1.0°C/W RθJC path to heatsink or PCB copper.
Is MBRS25100CTH pin-compatible with MBRS25100CT?
Yes, MBRS25100CTH and MBRS25100CT share identical TO-263AB (D2PAK) mechanical outline, pin assignment (Anode1–Anode2–Common Cathode), and thermal pad layout. The "H" suffix denotes halogen-free molding compound per IEC 61249-2-21, with no electrical or mechanical impact on PCB footprint or assembly.
What is the reverse leakage current of MBRS25100CTH at 100 V and 125°C?
Per the official Taiwan Semiconductor datasheet, MBRS25100CTH exhibits a maximum reverse leakage current (IR) of 7.5 mA at VR = 100 V and TJ = 125°C. This value is confirmed in the Electrical Specifications table on page 3 of Revision A2103 and reflects worst-case behavior under high-temperature, high-voltage bias conditions.
Does MBRS25100CTH require a moisture bake prior to reflow soldering?
No, MBRS25100CTH is rated at Moisture Sensitivity Level 1 (MSL-1) per J-STD-020, meaning it may be stored indefinitely at ≤30°C/60% RH and subjected to standard lead-free reflow profiles (e.g., JEDEC J-STD-020) without preconditioning bake. This simplifies SMT line integration and eliminates yield risk from moisture-induced popcorning.
How does the guard ring feature improve reliability in MBRS25100CTH?
The guard ring in MBRS25100CTH mitigates edge-related avalanche breakdown by controlling electric field distribution at the die periphery. This enhances ruggedness against high dv/dt transients (rated 10,000 V/μs) and improves survivability during repetitive surge events - critical for automotive applications like alternator rectification or motor drive freewheeling where voltage spikes exceed nominal ratings.
