Product details
Overview
VS-26MB100A from Vishay Semiconductors is a single-phase bridge rectifier with 25 A average forward current, 1000 V maximum repetitive peak reverse voltage (VRRM), and D-34 package featuring electrically insulated case and center-hole mounting. It delivers reliable AC-to-DC conversion in industrial power supplies and instrumentation front-ends where thermal robustness and UL E300359 compliance are required.
For engineers reviewing the VS-26MB100A datasheet, VS-26MB100A pinout, VS-26MB100A application, or VS-26MB100A equivalent, this page provides verified electrical ratings, thermal resistance data (RthJC = 1.7 K/W), terminal configuration, and direct alternatives for industrial-grade rectifier selection under high surge and continuous load conditions.
Technical Context
The VS-26MB100A implements a monolithic single-phase full-wave bridge topology with four integrated diodes in a common insulated D-34 housing. Its design supports universal termination (push-on, wrap-around, or solder) and operates across -55 °C to +150 °C junction temperature range.
It sustains non-repetitive surge currents up to 400 A (10 ms, 50 Hz, no voltage reapplied) and exhibits low forward voltage drop (VFM = 1.11 V at 40 Apk, TJ = 25 °C), enabling efficient power conversion in space-constrained industrial systems requiring high I2t robustness (790 A2s).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Average Forward Current (IO) | 25 A at TC = 65 °C - defines continuous DC output capability under heatsink-cooled operation |
| Peak Repetitive Reverse Voltage (VRRM) | 1000 V - sets maximum AC input voltage rating before breakdown in rectifier mode |
| Non-Repetitive Surge Current (IFSM) | 400 A (10 ms, 50 Hz, no voltage reapplied) - determines short-circuit withstand capability during line transients |
| Thermal Resistance (RthJC) | 1.7 K/W - quantifies junction-to-case heat transfer efficiency; critical for heatsink sizing |
| Forward Voltage Drop (VFM) | 1.11 V at 40 Apk, TJ = 25 °C - directly impacts conduction loss and thermal rise in steady-state operation |
| Isolation Voltage (VINS) | 2700 V RMS - ensures safe galvanic separation between baseplate and internal circuitry |
| Junction Temperature Range | -55 °C to +150 °C - specifies operational envelope for harsh-environment deployment |
Pinout & Package
D-34 package: compact, insulated plastic housing with center mounting hole, nickel-plated terminals compatible with Pb-free SAC305 solder (260–275 °C). Electrically isolated baseplate enables direct heatsink mounting without insulating washers.

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-26MB100N | Same electrical specs but non-insulated (conductive) metal case; RthJC = 1.5 K/W | Requires insulating kit for heatsink mounting; preferred where thermal performance outweighs isolation needs | Select VS-26MB100N only if external isolation is already implemented and lower thermal resistance is prioritized |
| ON Semiconductor GBPC2510 | 25 A / 1000 V, GBPC package (larger footprint), RthJC = 2.0 K/W, IFSM = 350 A (10 ms) | Compatible in function but requires PCB layout change; lower surge rating limits use in high-transient environments | Choose GBPC2510 only for legacy designs or cost-sensitive applications where D-34 size and 400 A surge are not mandatory |
Compared with VS-26MB100N and GBPC2510, the VS-26MB100A uniquely combines electrical insulation, 400 A surge capability, and 1.7 K/W thermal resistance in the compact D-34 form factor-making it optimal for new industrial designs demanding safety, robustness, and space efficiency without layout compromise.

FAQ
What is the maximum allowable case temperature for continuous operation of the VS-26MB100A?
The VS-26MB100A 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 current vs. case temperature curve in Figure 6 of the datasheet. Maintaining TC ≤ 65 °C ensures the junction stays within its -55 °C to +150 °C limit under typical thermal interface conditions. The VS-26MB100A must be mounted on an adequately sized heatsink with thermal grease to sustain this rating.
Does the VS-26MB100A require an insulating pad when mounted to a metal heatsink?
No, the VS-26MB100A does not require an insulating pad because its D-34 package features an electrically insulated case. The baseplate is isolated from internal semiconductor elements, allowing direct mounting to conductive heatsinks while maintaining 2700 V RMS isolation. This eliminates extra hardware, reduces thermal resistance, and simplifies assembly-key advantages confirmed in the "High thermal conductivity package, electrically insulated case" feature list of the VS-MB Series datasheet.
What is the forward voltage drop specification for the VS-26MB100A at rated current?
The VS-26MB100A has a maximum forward voltage drop (VFM) of 1.11 V at 40 A peak forward current, 25 °C junction temperature, and 400 μs pulse width. This value reflects conduction loss under transient conditions. For DC operation, the effective drop depends on thermal equilibrium-but the 1.11 V figure anchors worst-case power dissipation calculations (Pcond ≈ IO × VF) used in heatsink design for the VS-26MB100A.
Can the VS-26MB100A be used in 60 Hz applications?
Yes, the VS-26MB100A is fully rated for 60 Hz operation. Its non-repetitive surge current is specified at both 50 Hz (400 A) and 60 Hz (420 A), and its thermal derating curves apply identically across standard utility frequencies. The device's construction, thermal resistance (RthJC = 1.7 K/W), and I2t rating (725 A2s at 60 Hz) are validated for 60 Hz line-synchronized applications including North American industrial power supplies and motor drives using the VS-26MB100A.
What does the "100" in VS-26MB100A indicate?
The "100" in VS-26MB100A is the voltage code indicating a maximum repetitive peak reverse voltage (VRRM) of 1000 V. Per the Ordering Information Table and Voltage Ratings table in the VS-MB Series datasheet, voltage codes map directly: "100" × 10 = 1000 V. This distinguishes the VS-26MB100A from variants like VS-26MB060A (600 V) or VS-26MB120A (1200 V), all sharing the same 25 A current rating and D-34 package.
