Product details
Overview
MBR20100PTH from Taiwan Semiconductor is a 20A, 100V AEC-Q101-qualified Schottky barrier rectifier in TO-247AD (TO-3P) package, featuring 0.85V forward voltage at 10A/25°C, 150A surge current capability, and 1°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 MBR20100PTH datasheet, MBR20100PTH pinout, MBR20100PTH application, or MBR20100PTH equivalent, key selection criteria include its AEC-Q101 qualification, low VF at high temperature, dual-die construction, and UL recognition under file E-326243 - all critical for reliable high-current switching power designs.
Technical Context
This device implements a dual-die Schottky structure in a single TO-247AD package, enabling parallel conduction paths with matched thermal coupling. Its guard ring design provides overvoltage protection, and the matte tin-plated leads meet J-STD-002 solderability and JESD201 Class 2 whisker resistance requirements.
The MBR20100PTH operates across –55°C to +150°C junction temperature range with 10,000 V/μs critical dV/dt rating. At 125°C, it maintains 0.85V max forward voltage at 10A and exhibits only 5mA max reverse leakage at rated 100V reverse voltage.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IF (Continuous Forward Current) | 20 A - supports sustained high-current output rectification without derating below 100°C case temperature |
| VRRM (Repetitive Peak Reverse Voltage) | 100 V - enables use in 48V–72V nominal bus systems with 2× safety margin |
| VF @ 10A, 25°C | 0.85 V - reduces conduction loss by ~30% vs. comparable Si diodes, improving system efficiency |
| IFSM (Surge Current) | 150 A - withstands inrush and transient overloads in power supplies with 8.3ms half-sine waveform |
| RθJC (Junction-to-Case Thermal Resistance) | 1 °C/W - allows direct heatsink mounting with predictable thermal rise under full load |
| IR @ 100V, 125°C | 5 mA - low leakage preserves efficiency in high-temperature operation, e.g., under-hood automotive environments |
| AEC-Q101 Qualified | Yes - validated for automotive electronics per stress test requirements including HTGB, HTRB, and TCT |
Pinout & Package
Package: TO-247AD (TO-3P), 3-terminal through-hole package with isolated tab (cathode-connected tab), matte tin-plated leads, UL 94V-0 molding compound, 6.10g typical weight, polarity marked on device body.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Lead 1) | Input current terminal | Connected to input-side switching node; requires low-inductance layout to minimize ringing |
| Cathode (Lead 2) | Output current terminal | Electrically tied to metal tab; must be mounted to heatsink with electrically insulating but thermally conductive interface |
| Tab (Cathode) | Primary cathode path & thermal interface | Carries full forward current and dissipates heat; not isolated - grounding or isolation depends on PCB layout |
Key Features

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-20CPH10-M3 | Same 20A/100V rating, TO-247AC package, 0.82V VF @ 10A/25°C, no AEC-Q101 qualification | Targeted at industrial/commercial power supplies; lacks automotive stress validation | Select when AEC-Q101 is not required and lower VF at room temperature is prioritized |
| ON Semiconductor MBR20100CT | 20A/100V dual common-cathode Schottky in TO-220AB; 0.87V VF @ 10A/25°C; RθJC = 2.5°C/W | Suitable for cost-sensitive, lower-power (<1kW) applications with natural convection cooling | Select when board space permits TO-220 footprint and thermal budget allows higher RθJC |
Compared with VS-20CPH10-M3 and MBR20100CT, the MBR20100PTH delivers verified automotive reliability, superior thermal performance (1°C/W vs. ≥2.5°C/W), and tighter high-temperature leakage control - making it the preferred choice for thermally constrained, mission-critical 20A rectification.

FAQ
What is the maximum junction temperature rating for MBR20100PTH?
The MBR20100PTH has a maximum junction temperature (TJ) of +150°C, validated across its full operating range from –55°C to +150°C. This rating is supported by its 1°C/W junction-to-case thermal resistance and AEC-Q101 qualification, enabling reliable operation in under-hood automotive environments and high-ambient industrial settings where the MBR20100PTH is deployed as a primary output rectifier.
Is MBR20100PTH pin-compatible with other TO-247AD Schottky rectifiers?
Yes, the MBR20100PTH uses the standard TO-247AD (TO-3P) outline with Anode–Cathode–Tab pin assignment, matching mechanical and electrical mounting dimensions of industry-standard 3-lead TO-247AD rectifiers. However, thermal and electrical performance - such as RθJC, VF, and IR - must be verified individually, as the MBR20100PTH's dual-die construction and AEC-Q101 qualification differentiate it from generic TO-247AD parts.
Does MBR20100PTH have UL recognition?
Yes, the MBR20100PTH is UL Recognized under File #E-326243, confirming compliance with UL/CSA safety standards for component-level power semiconductors. This recognition applies to the TO-247AD package construction, flammability rating (UL 94V-0), and terminal plating - supporting its use in end equipment requiring UL certification, including industrial power supplies and telecom infrastructure where the MBR20100PTH serves as a certified rectification solution.
What is the forward voltage specification of MBR20100PTH at elevated temperature?
At 10A and 125°C junction temperature, the MBR20100PTH has a maximum forward voltage (VF) of 0.85V. This value is confirmed in the manufacturer's electrical specifications table and reflects stable conduction performance under high-thermal-load conditions - a key advantage over silicon diodes whose VF rises significantly with temperature, making the MBR20100PTH especially valuable in thermally demanding applications like automotive DC-DC converters.
How does the "H" suffix in MBR20100PTH indicate qualification status?
The "H" suffix in MBR20100PTH explicitly denotes AEC-Q101 qualification per the manufacturer's ordering information table. Unlike standard MBR20100PT variants, the MBR20100PTH undergoes full automotive stress testing - including high-temperature gate bias (HTGB), high-temperature reverse bias (HTRB), and temperature cycling - ensuring reliability for automotive power electronics where the MBR20100PTH is deployed in safety-critical DC-DC stages.
