Product details
Overview
VS-26MB10A from Infineon Technologies is a single-phase bridge rectifier module rated for 10 A average forward current (resistive/inductive load), 100 V repetitive peak reverse voltage (VRRM), and maximum junction temperature of 150 °C. It features electrically insulated case, 3.5 K/W junction-to-case thermal resistance, and UL E62320 approval - designed for compact AC/DC power supplies in instrumentation and general-purpose industrial equipment.
For engineers reviewing the VS-26MB10A datasheet, VS-26MB10A pinout, VS-26MB10A application, or VS-26MB10A equivalent, key selection criteria include its 100 V VRRM rating, 1.3 V max forward voltage at 31.4 A pulse, 10 µA max reverse leakage per diode at 25 °C, and compatibility with push-on/wrap-around/solder termination methods.
Technical Context
The VS-26MB10A integrates four silicon diodes in a single-phase full-wave bridge configuration within an epoxy-encapsulated, electrically insulated package. Its thermal design supports direct mounting to heatsinks via center-hole fixing, with RthJC = 3.5 K/W and RthCS = 0.2 K/W (greased interface).
It operates across -40 °C to +150 °C junction temperature range and delivers stable rectification under capacitive, inductive, or resistive loads. The device sustains non-repetitive surge currents up to 148 A (10 ms, 50 Hz) and exhibits low forward conduction losses via VF(TO)1 = 1.00 V and rt1 = 15.4 mΩ at TJ max.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Maximum repetitive reverse voltage each diode withstands without breakdown; defines safe AC input voltage ceiling (e.g., ≤70 V RMS). |
| IO (AV) | 10 A - Continuous DC output current capability at TC = 65 °C with resistive/inductive load; determines sustained power delivery capacity. |
| IFSM (50 Hz) | 148 A - Peak one-cycle surge current tolerance (10 ms); critical for handling inrush during cold-start of transformer-coupled supplies. |
| VF(M) | 1.3 V - Max forward voltage drop at TJ = 25 °C, IFM = π × IO(AV) ≈ 31.4 A, tp = 400 µs; directly impacts conduction loss and thermal rise. |
| RthJC | 3.5 K/W - Junction-to-case thermal resistance per bridge; enables thermal modeling when mounted on heatsink with known RthCS. |
| IRRM | 10 µA - Max DC reverse current per diode at VRRM and TJ = 25 °C; ensures minimal leakage in high-impedance or precision sensing circuits. |
| VINS | 2700 V RMS - Isolation voltage between baseplate and internal circuitry (50 Hz, 1 s); certifies safety in mains-connected equipment. |
Pinout & Package
VS-26MB10A uses a 4-terminal, single-phase bridge rectifier package with universal 3-way termination: push-on faston, wrap-around, or solder. Case is electrically insulated and features center mounting hole (M4, torque 2.0 Nm). Approximate weight: 20 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| AC1 | AC Input Terminal 1 | One leg of AC input; connects to transformer secondary or line input; shares common cathode node internally with AC2. |
| AC2 | AC Input Terminal 2 | Second leg of AC input; completes full-wave bridge input path; symmetrical with AC1 for bidirectional conduction. |
| + (DC+) | Positive DC Output | Anode of both upper diodes; delivers rectified positive output; must connect to bulk capacitor or downstream regulator. |
| – (DC–) | Negative DC Output / Common Return | Cathode of both lower diodes; serves as system ground reference and return path for DC load current. |
Key Features
| Feature | Design Value |
|---|---|
| Electrically insulated case | Enables direct mounting to grounded heatsinks without isolation hardware; reduces BOM count and assembly steps. |
| Universal 3-way terminals | Supports push-on (200 N max axial force), wrap-around, or solder termination - simplifies integration across prototyping and production. |
| UL E62320 approval | Validates compliance with safety standards for double-insulated mains-connected equipment; eliminates need for additional certification testing. |
| High power/volume ratio | Delivers 10 A rectification in compact encapsulated module (typ. 20 g, ~25 mm × 20 mm footprint); saves PCB space vs discrete diode solutions. |
| Low thermal resistance | RthJC = 3.5 K/W and RthCS = 0.2 K/W (greased) enable efficient heat transfer - supports higher ambient temperatures or reduced heatsink size. |

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-GBPC10A | Same 10 A IO, 100 V VRRM, but TO-247-4L package with non-insulated case; RthJC = 2.5 K/W. | Requires insulating kit for heatsink mounting; better thermal performance but adds assembly complexity. | Select when thermal budget is tighter and isolation can be added externally. |
| ON Semiconductor GBPC1004 | 10 A IO, 400 V VRRM, same MB-series footprint; RthJC = 3.0 K/W; IRRM = 5 µA at 25 °C. | Higher voltage rating suits 230 V AC inputs; lower leakage benefits precision analog supplies. | Select when designing for dual-voltage (115/230 V) global markets or ultra-low-leakage requirements. |
Compared with VS-26MB10A, VS-GBPC10A offers superior thermal resistance but requires external insulation, while GBPC1004 provides higher VRRM and lower IRRM at the cost of over-spec'ing for 100 V applications - making VS-26MB10A optimal for cost-sensitive, safety-certified 115 V AC instrumentation designs.

FAQ
What is the maximum allowable case temperature for continuous operation of the VS-26MB10A?
The VS-26MB10A supports continuous operation at a maximum case temperature (TC) of 65 °C when delivering its rated 10 A average forward current into resistive or inductive loads. Exceeding this temperature requires derating per the current ratings curves in Bulletin I2715 - for example, at TC = 50 °C, IO increases to ~12.5 A. Thermal design must account for RthJC = 3.5 K/W and RthCS = 0.2 K/W to maintain junction temperature below 150 °C.
Does the VS-26MB10A require external insulation when mounted to a metal heatsink?
No - the VS-26MB10A features an electrically insulated case certified to 2700 V RMS isolation (VINS), enabling direct mounting to grounded or floating metal heatsinks without insulating pads or sleeves. This simplifies mechanical design and improves thermal reliability. Mounting torque must be maintained at 2.0 Nm ±10% using the center fixing hole, and the interface surface must be smooth, flat, and greased to achieve the specified RthCS = 0.2 K/W.
What is the forward voltage drop of the VS-26MB10A under typical operating conditions?
The VS-26MB10A exhibits a maximum forward voltage drop (VFM) of 1.3 V at TJ = 25 °C, with instantaneous forward current IFM = π × IO(AV) ≈ 31.4 A and pulse width tp = 400 µs. At elevated junction temperature (TJ = 150 °C), the threshold voltage VF(TO)1 is 1.00 V and slope resistance rt1 is 15.4 mΩ - meaning VF rises linearly with current above ~5.2 A. This behavior is critical for calculating conduction losses in thermal models.
Can the VS-26MB10A be used in capacitive-load applications?
Yes, the VS-26MB10A supports capacitive-load operation, though with reduced current rating: 8 A average forward current (vs. 10 A for resistive/inductive loads) at TC = 65 °C. This derating accounts for higher peak currents and increased thermal stress caused by capacitor charging transients. Designers must verify surge current limits (IFSM = 148 A) and I²t fusing values (110 A²s at 10 ms) against their specific input capacitor size and inrush profile.
Is the VS-26MB10A RoHS compliant and halogen-free?
Yes, the VS-26MB10A conforms to RoHS Directive 2011/65/EU and is halogen-free per IEC 61249-2-21. Infineon documents this compliance in material declarations aligned with IPC-1752A, and the device carries the "RoHS-compliant" marking on its packaging and datasheet. No exemptions apply - all lead content is below 0.1 wt%, and brominated flame retardants are absent from the epoxy encapsulant.
