Product details
Overview
VS-26MT20 from Vishay Semiconductors is a three-phase bridge rectifier with 25 A average output current, 200 V maximum repetitive peak reverse voltage (VRRM), and D-63 insulated package. It delivers reliable AC-to-DC conversion in motor drives and industrial power supplies, featuring nickel-plated terminals compatible with Pb-free SAC305 solder at 260–275 °C.
For engineers reviewing the VS-26MT20 datasheet, VS-26MT20 pinout, VS-26MT20 application, or VS-26MT20 equivalent, key selection criteria include thermal resistance (RthJC = 1.42 K/W), surge current capability (IFSM = 360 A at 50 Hz), forward voltage drop (VFM = 1.26 V at 25 °C), and UL E300359 approval for safety-critical deployments.
Technical Context
This device integrates six diodes in a single-phase-input, three-phase-output bridge configuration with electrically insulated case and center-hole mounting. Its D-63 package enables direct heatsink attachment via M4 screw (2.0 Nm torque) and supports universal terminal connection methods: push-on, wrap-around, or solder.
Thermal performance is defined by junction-to-case resistance of 1.42 K/W under DC operation and RMS isolation voltage of 2700 V at 50 Hz. The device operates across -55 °C to +150 °C and sustains 100 µA max reverse current per junction at rated VRRM and 25 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IO (Avg) | 25 A - continuous DC output current at TC = 70 °C with 120° conduction angle |
| VRRM | 200 V - maximum repetitive peak reverse voltage; defines safe AC input swing before breakdown |
| IFSM (50 Hz) | 360 A - non-repetitive surge current handling without damage during startup or fault conditions |
| VFM | 1.26 V - forward voltage drop per junction at 40 A peak and 25 °C; directly impacts conduction loss and thermal design |
| RthJC | 1.42 K/W - junction-to-case thermal resistance; determines minimum heatsink requirement for 150 °C max TJ |
| VINS | 2700 V - RMS isolation voltage between all terminals and case; validates reinforced insulation for safety compliance |
| IRRM | 100 µA - max reverse leakage per junction at 25 °C and rated VRRM; critical for low-power standby efficiency |
Pinout & Package

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 |
|---|---|---|---|
| VSKD26/04 | Same 25 A IO and D-63 package, but VRRM = 400 V; higher VF(TO)1 (0.95 V vs. 0.88 V) | Better suited for 400 VAC industrial grids; less optimal for 200 VAC-rated equipment due to over-spec'd voltage margin | Select VSKD26/04 only when system requires >300 V VRRM headroom or operates on 400 VAC nominal supply. |
| VS-36MT20 | Higher 35 A IO rating, same 200 V VRRM, lower RthJC (1.35 K/W), but larger thermal mass and 2.0 Nm mounting torque unchanged | Direct upgrade path for higher-current designs; requires verification of heatsink capacity and PCB layout clearance | Choose VS-36MT20 when output current demand exceeds 25 A or ambient temperature exceeds 70 °C at full load. |
Compared with VSKD26/04 and VS-36MT20, the VS-26MT20 offers optimal balance of 200 V VRRM headroom, 25 A output, and 1.42 K/W thermal resistance for cost-sensitive 3-phase rectification where voltage and current margins are tightly matched to application requirements.

FAQ
What is the maximum case temperature for continuous operation of the VS-26MT20?
The VS-26MT20 supports continuous operation up to 70 °C case temperature (TC) at its rated 25 A DC output current with 120° conduction angle. Exceeding this temperature requires derating per Fig. 6 in the datasheet, and thermal design must ensure junction temperature remains ≤150 °C using the 1.42 K/W RthJC value.
Does the VS-26MT20 require external insulation when mounted to a metal heatsink?
No - the VS-26MT20 features an electrically insulated case qualified to 2700 V RMS isolation. It can be safely bolted directly to a grounded heatsink without additional insulating washers or pads, simplifying mechanical integration and improving thermal transfer efficiency.
What solder profile is recommended for VS-26MT20 terminals?
The VS-26MT20 terminals are nickel-plated and qualified for Pb-free SAC305 solder with peak temperatures of 260–275 °C. Reflow profiles must comply with JEDEC J-STD-020, and dwell time above 220 °C should not exceed 60 seconds to avoid degradation of internal encapsulation.
Is the VS-26MT20 certified for use in safety-critical applications?
Yes - the VS-26MT20 carries UL E300359 recognition, confirming compliance with UL/CSA 60950-1 and IEC 62368-1 for reinforced insulation. This certification supports its use in industrial equipment requiring third-party safety validation, though final system-level approval remains the customer's responsibility.
How does the forward voltage drop of VS-26MT20 affect power loss at full load?
At 25 A average output and 25 °C, the VS-26MT20 exhibits VFM = 1.26 V per junction. With six active diodes conducting in sequence, total conduction loss approximates 31.5 W (1.26 V × 25 A), which must be dissipated via the heatsink - a key input to thermal design using RthJC = 1.42 K/W.
