Product details
Overview
VS-26MT10 from Vishay Semiconductors is a compact, encapsulated three-phase bridge rectifier rated for 25 A DC output current at 70 °C case temperature, with 100 V maximum repetitive peak reverse voltage (VRRM), UL E300359 approved, and housed in the electrically insulated D-63 package. It delivers reliable AC-to-DC conversion in industrial motor drives and instrumentation power supplies.
For engineers reviewing the VS-26MT10 datasheet, VS-26MT10 pinout, VS-26MT10 application, or VS-26MT10 equivalent, key selection criteria include its 25 A thermal current rating, 1.42 K/W junction-to-case thermal resistance, 1.26 V forward voltage drop at 40 A peak per junction, and compatibility with Pb-free soldering at 260–275 °C.
Technical Context
This device integrates six silicon diodes in a single-phase-input, three-phase-output bridge configuration with common-cathode and common-anode terminals. Its D-63 package features electrically insulated metal base, center-hole mounting, and universal 3-way terminals (push-on, wrap-around, or solder).
Designed for 50/60 Hz line-frequency rectification, it supports non-repetitive surge currents up to 360 A (10 ms, 50 Hz) and 375 A (8.3 ms, 60 Hz) at initial junction temperature of 150 °C, with RMS isolation voltage of 2700 V between all terminals and case.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IO (DC Output Current) | 25 A at TC = 70 °C - defines continuous load capability under heatsink-cooled conditions |
| VRRM (Max Repetitive Peak Reverse Voltage) | 100 V - determines maximum AC line voltage it can block without breakdown |
| IFSM (Non-repetitive Peak Forward Surge Current) | 375 A at 60 Hz, 8.3 ms - specifies short-circuit withstand capability during startup/fault |
| VFM (Max Forward Voltage Drop) | 1.26 V at TJ = 25 °C, IFM = 40 A per junction - directly impacts conduction loss and thermal design |
| RthJC (Junction-to-Case Thermal Resistance) | 1.42 K/W - enables thermal modeling for heatsink sizing and derating curves |
| IRRM (Max Reverse Leakage Current) | 100 µA at TJ = 25 °C, rated VRRM - critical for low-power standby or high-impedance sensing circuits |
| VINS (RMS Isolation Voltage) | 2700 V - certifies safety insulation between terminals and metal case for industrial grounding |
Pinout & Package
The VS-26MT10 uses the D-63 package: 24 mm × 28.5 mm × 22 mm metal-base, electrically insulated case with center mounting hole (Ø5.2 mm), smooth flat mounting surface, and three AC input terminals (AC1, AC2, AC3) plus positive (+) and negative (–) DC output terminals.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| AC1, AC2, AC3 | Three-phase AC inputs | Accepts balanced 3-phase AC line inputs; symmetrical layout minimizes parasitic inductance |
| + | DC output anode (common cathode node) | Delivers rectified positive DC bus; electrically isolated from case for flexible grounding schemes |
| – | DC output cathode (common anode node) | Serves as return path; terminal polarity must match downstream capacitor and load connections |
Key Features
| Feature | Design Value |
|---|---|
| UL E300359 approval | Validates safety compliance for industrial equipment requiring recognized component certification |
| Electrically insulated case | Enables direct mounting to grounded heatsinks without additional isolation hardware or thermal pads |
| Universal 3-way terminals | Supports push-on, wrap-around, or solder termination - simplifies assembly across prototyping and production |
| Pb-free solder compatibility | Rated for SAC305 alloy reflow at 260–275 °C - ensures reliability in modern RoHS-compliant manufacturing |
| High power/volume ratio | 25 A in 12 cm³ footprint - reduces system size versus discrete diode solutions while maintaining thermal margin |

Equivalent & Alternatives
The following parts are listed as comparable options for similar three-phase bridge rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| VS-26MT05 | VRRM = 50 V (vs. 100 V); identical IO, package, and thermal specs | Limited to lower-voltage 3-phase systems (e.g., 208 VAC line); unsuitable for 400 VAC+ applications | Select only when system peak reverse voltage remains ≤50 V - avoids overdesign and cost premium |
| VS-36MT10 | Higher IO = 35 A at TC = 60 °C; same VRRM = 100 V; RthJC = 1.35 K/W | Better suited for higher-current or higher-ambient designs where derating headroom is critical | Choose when sustained load exceeds 22 A at >55 °C ambient - provides margin without changing PCB layout |
Compared with VS-26MT05, VS-26MT10 offers double the reverse voltage blocking; compared with VS-36MT10, it trades 10 A current capacity for 10 °C higher allowable case temperature - enabling simpler thermal management in space-constrained enclosures.

FAQ
What is the maximum case temperature for continuous operation of the VS-26MT10?
The VS-26MT10 is rated for 25 A DC output current at a maximum case temperature (TC) of 70 °C. Operation above this temperature requires linear derating per the datasheet's Fig. 6 curve. Exceeding 70 °C without adjustment risks thermal runaway due to increased forward voltage drop and leakage current. Always verify heatsink interface resistance and ambient airflow when designing for elevated TC.
Does the VS-26MT10 support lead-free soldering processes?
Yes, the VS-26MT10 is qualified for Pb-free soldering using Sn/Ag/Cu (SAC305) alloy at peak temperatures of 260–275 °C. Its nickel-plated terminals ensure robust wetting and intermetallic formation without voiding or dewetting. Reflow profiles must limit time above 220 °C to ≤60 seconds to preserve internal bond integrity and insulation performance.
What is the isolation voltage rating between terminals and case for VS-26MT10?
The VS-26MT10 provides 2700 V RMS isolation voltage (VINS) between all terminals (AC1/AC2/AC3/+/-) and the metal case, tested at 50 Hz for 1 second at 25 °C. This rating enables safe use in grounded-chassis industrial equipment and satisfies reinforced insulation requirements for SELV secondary circuits when properly mounted with dielectric grease or insulating washers.
Can VS-26MT10 be used in single-phase rectification applications?
Yes, the VS-26MT10 can be used in single-phase full-wave rectification by connecting two AC terminals (e.g., AC1 and AC2) to the AC source and leaving AC3 unconnected. However, its 25 A rating applies only to three-phase operation; single-phase use reduces effective current capacity due to uneven junction utilization and higher thermal stress on active diodes - consult Fig. 7 derating curves before deployment.
What mounting torque is required for the VS-26MT10 screw attachment?
The VS-26MT10 requires a mounting torque of 2.0 Nm ± 10 % when secured to a heatsink using an M4 screw. Under-torquing increases thermal resistance and risks overheating; over-torquing may deform the D-63 case or crack the epoxy encapsulation. Use calibrated torque tools and apply thermal interface material evenly across the full mounting surface to achieve the specified 0.2 K/W case-to-heatsink resistance.
