Product details
Overview
VS-26MB60A from Vishay Semiconductors is a single-phase bridge rectifier in D-34 package, rated for 25 A average forward current, 600 V maximum repetitive peak reverse voltage (VRRM), and 1.11 V maximum forward voltage drop at 40 A peak. It features electrically insulated case, UL E300359 approval, and is designed for industrial power supplies and AC/DC conversion in instrumentation systems.
For engineers reviewing the VS-26MB60A datasheet, VS-26MB60A pinout, VS-26MB60A application, or VS-26MB60A equivalent, this page delivers verified electrical ratings, thermal resistance (RthJC = 1.7 K/W), mounting torque (2.0 Nm), isolation voltage (2700 V RMS), and real-world surge capability (IFSM = 420 A at 60 Hz) - all critical for high-reliability rectifier selection.
Technical Context
The VS-26MB60A implements a monolithic single-phase full-wave bridge configuration with four integrated silicon diodes in a thermally optimized, electrically isolated D-34 package. Its design supports universal terminal options (push-on, wrap-around, solder) and operates across -55 °C to +150 °C junction temperature range.
It delivers stable DC output under resistive, inductive, or capacitive loads - with derated IO of 20 A for capacitive loads - and sustains non-repetitive surge currents up to 420 A (60 Hz, 8.3 ms) without voltage reapplied, validated at initial TJ = 150 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Average Forward Current (IO) | 25 A at TC = 65 °C - defines continuous DC output capability under standard heatsink conditions |

| Forward Voltage Drop (VFM) | 1.11 V at IFM = 40 A, TJ = 25 °C - directly determines conduction loss and thermal load in power stage |
| Surge Current (IFSM) | 420 A at 60 Hz, t = 8.3 ms - specifies short-duration overload tolerance during startup or line transients |
| Thermal Resistance (RthJC) | 1.7 K/W - quantifies junction-to-case heat transfer efficiency; critical for heatsink sizing |
| Isolation Voltage (VINS) | 2700 V RMS, 50 Hz, 1 s - ensures safe galvanic separation between AC terminals and baseplate |
| Mounting Torque | 2.0 Nm ± 10 % - required mechanical clamping force to maintain thermal interface integrity with heatsink |

Equivalent & Alternatives
The following parts are listed as comparable options for similar single-phase bridge rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-26MB80A | Higher VRRM = 800 V; identical IO = 25 A, RthJC = 1.7 K/W, and D-34 package | Suitable where higher line-voltage margin or transient immunity is required (e.g., 400 V AC industrial grids) | Select VS-26MB80A when system-level surge testing exceeds 600 V or when future-proofing against voltage upgrades |
| ON Semiconductor GBPC2506 | Same IO = 25 A, VRRM = 600 V, but TO-247-4L package; RthJC = 2.0 K/W; no baseplate isolation | Requires external insulator and different mounting hardware; lower thermal performance limits power density | Choose GBPC2506 only if legacy TO-247 footprint compatibility is mandatory and isolation can be added externally |
Compared with VS-26MB80A and GBPC2506, the VS-26MB60A offers optimal balance of voltage rating, thermal performance, and integrated isolation - enabling simpler, safer, and more compact industrial power designs without compromising surge resilience or manufacturability.

FAQ
What is the maximum allowable case temperature for continuous operation of the VS-26MB60A?
The VS-26MB60A supports continuous operation at a maximum case temperature (TC) of 65 °C while delivering its rated 25 A average forward current. Exceeding this temperature requires derating per the datasheet's current vs. case temperature curve. The device's junction temperature remains within its -55 °C to +150 °C range as long as thermal design maintains TC ≤ 65 °C under full load. This limit ensures long-term reliability and prevents premature degradation of the epoxy encapsulation and internal metallization in the VS-26MB60A.
Does the VS-26MB60A require an insulating pad when mounted to a heatsink?
No, the VS-26MB60A does not require an external insulating pad because its metal baseplate is electrically isolated from all terminals - confirmed by its 2700 V RMS isolation voltage rating. This built-in insulation allows direct mounting to grounded heatsinks, eliminating thermal interface layers that increase RthCS. The VS-26MB60A's design inherently supports simplified thermal management and reduced bill-of-materials cost compared to non-isolated alternatives.
What is the forward voltage drop specification for the VS-26MB60A at elevated temperature?
The VS-26MB60A's maximum forward voltage drop (VFM) is specified as 1.11 V at TJ = 25 °C and IFM = 40 A. At maximum junction temperature (150 °C), VFM increases due to diode physics - typical curves show ~1.25–1.30 V under same current. This temperature-dependent rise must be accounted for in worst-case power loss calculations for the VS-26MB60A, especially in high-ambient industrial environments.
Can the VS-26MB60A be used with lead-free soldering processes?
Yes, the VS-26MB60A features nickel-plated terminals qualified for lead-free soldering using Sn/Ag/Cu (SAC305) alloy at peak temperatures of 260–275 °C. Its terminal plating and encapsulation withstand standard reflow profiles without delamination or intermetallic degradation. This makes the VS-26MB60A fully compatible with modern RoHS-compliant manufacturing lines and eliminates need for special process adjustments during assembly.
How does the VS-26MB60A handle surge currents during cold start?
The VS-26MB60A sustains 420 A non-repetitive surge current for 8.3 ms at 60 Hz with no voltage reapplied - a condition representative of cold-start inrush into large input capacitors. Its I2t rating of 725 A2s (60 Hz) provides quantitative fusing protection margin. This surge capability is validated at initial TJ = 150 °C, ensuring robustness even after prolonged operation before startup - a key reliability factor for the VS-26MB60A in mission-critical power systems.
