Product details
Overview
VS-MURB1020CT-1-M3 from Vishay Semiconductors is a dual ultrafast rectifier in TO-262AA package with common cathode configuration, rated for 2 × 5 A average forward current per leg, 200 V peak repetitive reverse voltage, and 25 ns typical reverse recovery time at TJ = 25 °C. It serves as output rectifier in high-frequency SMPS and DC/DC converters where low switching loss and thermal robustness up to 175 °C junction temperature are critical.
For engineers reviewing the VS-MURB1020CT-1-M3 datasheet, VS-MURB1020CT-1-M3 pinout, VS-MURB1020CT-1-M3 application, or VS-MURB1020CT-1-M3 equivalent, this page delivers verified electrical parameters, thermal resistance data, real-world recovery characteristics, and validated alternative options for power supply design and replacement sourcing.
Technical Context
This device integrates two platinum-doped FRED Pt® die in a single common-cathode TO-262AA package, enabling synchronous rectification or dual-leg operation without external interconnection. Its planar structure and lifetime-controlled carrier recombination yield ultrafast trr (24–35 ns) and low Qrr (33–76 nC), directly reducing snubber dissipation and MOSFET/FET switching stress.
The 5 °C/W thermal resistance junction-to-case per leg and 175 °C maximum junction temperature support high-power density designs in constrained thermal environments. With VF = 0.87 V at IF = 5 A and TJ = 125 °C, it maintains low conduction loss across industrial operating temperatures while meeting J-STD-020 MSL Level 1.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Reverse Voltage (VRRM) | 200 V - supports input/output isolation in 12–48 V DC/DC and UPS systems with 20 % safety margin. |
| Average Forward Current (IF(AV)) | 2 × 5 A - enables dual 5 A output rails or parallel-leg operation without derating at TC = 149 °C. |
| Forward Voltage (VF) | 0.87 V @ 5 A, 125 °C - reduces conduction loss to ≤4.35 W per leg under full load at elevated temperature. |
| Reverse Recovery Time (trr) | 24 ns @ 5 A, 125 °C - minimizes dead-time losses and EMI generation in >100 kHz switching topologies. |
| Junction-to-Case Thermal Resistance (RthJC) | 5 °C/W per leg - allows direct heatsink mounting with predictable thermal rise of ≤25 °C at 5 A continuous. |
| Operating Junction Temperature (TJ max) | 175 °C - ensures reliability in sealed enclosures or high-ambient industrial motor drives and inverters. |
| Reverse Leakage Current (IR) | 250 μA @ VR = 200 V, TJ = 150 °C - maintains low standby loss in offline auxiliary supplies. |
Pinout & Package
VS-MURB1020CT-1-M3 uses the TO-262AA (3-lead, straight lead) package with exposed metal base acting as common cathode terminal. The package complies with JEDEC TO-262 mechanical outline and supports surface-mount-compatible through-hole assembly.
| Pin/Terminal | Circuit Role | Design Meaning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultrafast dual rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH10L06TV1 | 600 V VRRM, 10 A total IF(AV), TO-220AC package, trr = 35 ns @ 25 °C | Higher voltage rating suits 400 V bus applications; larger RthJA (60 °C/W) requires larger heatsink | Select when 600 V blocking is required and TO-220 footprint is acceptable; not drop-in for TO-262AA board layout |
| IXYS MUR1020CT | Same 200 V / 2×5 A rating, TO-220AB package, trr = 30 ns @ 25 °C, VF = 0.92 V @ 5 A, 25 °C | Higher VF at elevated temperature increases conduction loss; lacks -M3 environmental compliance | Use only if TO-220AB mounting is available and halogen-free/RoHS is not mandated; no pin compatibility with VS-MURB1020CT-1-M3 |
Compared with STTH10L06TV1 and IXYS MUR1020CT, VS-MURB1020CT-1-M3 delivers superior thermal performance (5 °C/W vs. ≥30 °C/W), lower VF at high temperature, and guaranteed MSL Level 1 handling-making it optimal for compact, high-reliability industrial power supplies where thermal management and manufacturability are critical.

FAQ
What is the package type of VS-MURB1020CT-1-M3?
VS-MURB1020CT-1-M3 uses the TO-262AA package-a 3-lead, straight-lead variant of JEDEC TO-262 with an exposed metal base serving as the common cathode terminal. This package provides low thermal resistance (5 °C/W per leg) and is distinct from the D2PAK (TO-263AB) version labeled VS-MURB1020CT-M3.
Does VS-MURB1020CT-1-M3 support surface-mount assembly?
No-VS-MURB1020CT-1-M3 is a through-hole device in TO-262AA package and requires hole-mounting with leads bent for PCB retention. While its thermal pad is compatible with heatsink attachment, it is not designed for reflow soldering like SMD packages. For SMT alternatives, consider VS-MURB1020CT-M3 in D2PAK.
What is the maximum reverse recovery time (trr) specification for VS-MURB1020CT-1-M3?
The maximum reverse recovery time for VS-MURB1020CT-1-M3 is 35 ns, measured at TJ = 25 °C with IF = 1.0 A, dIF/dt = 50 A/μs, and VR = 30 V. At elevated conditions (IF = 5 A, TJ = 125 °C, VR = 160 V), typical trr is 35 ns, with a minimum of 24 ns specified in the datasheet.
Is VS-MURB1020CT-1-M3 pin-compatible with VS-MURB1020CT-M3?
No-VS-MURB1020CT-1-M3 (TO-262AA) and VS-MURB1020CT-M3 (D2PAK/TO-263AB) have different footprints, lead forms, and mechanical outlines. They share identical electrical specifications but require separate PCB layouts; neither is a drop-in replacement for the other.
What does the "-M3" suffix indicate in VS-MURB1020CT-1-M3?
The "-M3" suffix denotes Vishay's environmental compliance grade: halogen-free construction, RoHS-compliant materials, and lead (Pb)-free terminations. It also confirms compliance with J-STD-020 MSL Level 1, permitting unlimited floor life and standard reflow without preconditioning.
