Product details
Overview
MBRB10100-M3/8W from Vishay General Semiconductor is a high-voltage Trench MOS Barrier Schottky (TMBS®) rectifier in D2PAK (TO-263AB) package, rated for 100 V repetitive peak reverse voltage, 10 A average forward current, and 150 A non-repetitive surge current. It delivers low 0.65 V forward voltage at 10 A and 125 °C, enabling high-efficiency DC/DC converters and switching power supplies.
For engineers reviewing the MBRB10100-M3/8W datasheet, MBRB10100-M3/8W pinout, MBRB10100-M3/8W application, or MBRB10100-M3/8W equivalent, this page provides verified electrical parameters, thermal resistance (RθJC = 2.0 °C/W), junction capacitance (typ. 200 pF at 10 V), surge capability, and real-world use context for industrial and telecom power designs.
Technical Context
This TMBS® rectifier uses trench MOS Schottky architecture to reduce forward voltage and leakage versus planar Schottky diodes, while maintaining fast recovery and high dV/dt rating (10,000 V/μs). Its single-die configuration supports unidirectional conduction with cathode-marked polarity and heatsink-connected tab.
Designed for high-frequency operation up to several MHz, it avoids minority-carrier storage delay and eliminates reverse recovery loss-critical in synchronous rectification and freewheeling paths where efficiency and thermal management are constrained.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - blocks up to 100 V repetitive reverse voltage without breakdown |
| IF(AV) | 10 A at TC = 133 °C - continuous forward current rating under heatsink-cooled conditions |
| IFSM | 150 A (8.3 ms half-sine) - withstands short-duration inrush and fault currents |
| VF | 0.65 V at IF = 10 A, TJ = 125 °C - enables low conduction loss in high-temp power stages |
| RθJC | 2.0 °C/W - low junction-to-case thermal resistance supports direct heatsink mounting |
| IR | 6.0 mA at VR = 100 V, TJ = 125 °C - low leakage preserves efficiency in high-temp DC/DC outputs |
| dV/dt | 10,000 V/μs - resists false triggering in fast-switching topologies like LLC resonant converters |
Pinout & Package
Package: D2PAK (TO-263AB) - surface-mount, thermally enhanced plastic package with exposed metal tab for heatsink attachment. Meets UL 94 V-0, RoHS-compliant, halogen-free, JESD201 Class 1A whisker-tested.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode | Input terminal for forward conduction; connects to switching node or input rail |
| Pin 2 | Cathode | Output terminal; marked "K" on package; connects to output filter or load return |
| Tab (Pin 3) | Cathode / Heatsink Interface | Electrically tied to cathode; must be isolated from chassis unless circuit design permits common-cathode grounding |
Key Features
| Feature | Design Value |
|---|---|
| Trench MOS Schottky technology | Reduces VF by ~15–20% vs. planar Schottky at same rating, lowering conduction loss in 12–48 V systems |
| Low VF (0.65 V @ 10 A, 125 °C) | Enables >95% efficiency in 12 V → 5 V/3.3 V buck converters at full load |
| High IFSM (150 A) | Survives cold-start surges and transient overloads without degradation in server PSU front-ends |
| MSL Level 1 (245 °C peak) | Compatible with standard lead-free reflow profiles without moisture sensitivity handling |
| Junction temp max = 150 °C | Supports operation in sealed enclosures or high-ambient environments (e.g., outdoor telecom cabinets) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STPS10H100CG-TR | 100 V, 10 A, VF = 0.72 V @ 10 A, 150 °C; TO-263 package; higher VF, lower dV/dt (5,000 V/μs) | Suitable for lower-frequency (<500 kHz) SMPS where thermal margin allows higher VF | Prefer MBRB10100-M3/8W when minimizing conduction loss or operating above 1 MHz |
| ON Semi NRVB10100CTT4G | 100 V, 10 A dual common-cathode die; VF = 0.75 V @ 10 A, 125 °C; TO-220AC package; no exposed tab | Used in dual-output or redundant rectifier configurations; requires through-hole mounting and separate heatsinking | Choose MBRB10100-M3/8W for SMT density, lower RθJC, and simplified thermal design |
Compared with STPS10H100CG-TR and NRVB10100CTT4G, the MBRB10100-M3/8W offers superior thermal performance (RθJC = 2.0 °C/W), lower forward voltage, and higher dV/dt tolerance-making it optimal for compact, high-frequency, high-reliability power stages where board space and thermal headroom are constrained.

FAQ
What is the maximum junction temperature rating for the MBRB10100-M3/8W?
The MBRB10100-M3/8W has a maximum junction temperature (TJ max.) of +150 °C, validated per JEDEC standards. This rating enables reliable operation in sealed or high-ambient environments such as telecom base stations and industrial control cabinets. Derating curves confirm 10 A average current is sustainable at case temperatures up to 133 °C, provided thermal design meets RθJC = 2.0 °C/W.
Is the MBRB10100-M3/8W RoHS-compliant and halogen-free?
Yes, the MBRB10100-M3/8W is RoHS-compliant and halogen-free, as confirmed by Vishay's material categorization documentation (www.vishay.com/doc?99912). The "M3" suffix denotes compliance with JESD201 Class 1A whisker testing and adherence to commercial-grade environmental specifications, making it suitable for consumer, industrial, and telecom applications without restriction.
What does the "/8W" suffix indicate in MBRB10100-M3/8W?
"/8W" specifies the packaging format: tape-and-reel delivery with 800 units per reel. This contrasts with "/4W", which denotes tube packaging (50 units per tube). Both share identical electrical and thermal specifications; the suffix only reflects logistics and assembly compatibility-not device performance or revision level.
Can the MBRB10100-M3/8W replace the MBRB1090-M3 in a 90 V design?
The MBRB10100-M3/8W is rated for 100 V VRRM versus 90 V for the MBRB1090-M3, making it a safe functional upgrade in 90 V applications. However, VF and thermal characteristics are nearly identical, so no layout or thermal redesign is needed. Note that the MBRB10100-M3/8W is not a drop-in replacement if the original design relies on tighter 90 V margin for cost or qualification reasons.
Does the MBRB10100-M3/8W require a heatsink in typical operation?
Yes-the D2PAK package's exposed cathode tab is designed for direct heatsink attachment. With RθJC = 2.0 °C/W and 10 A conduction loss generating ~6.5 W (at VF = 0.65 V), a heatsink is required to maintain TJ ≤ 150 °C. Without heatsinking, junction temperature rise would exceed safe limits even at moderate ambient temperatures.
