Product details
Overview
VS-36MB100A from Vishay Semiconductors is a single-phase bridge rectifier rated for 35 A average forward current, 1000 V maximum repetitive peak reverse voltage (VRRM), and 475 A non-repetitive surge current at 50 Hz. It features a D-34 package with electrically insulated case, UL E300359 approval, and nickel-plated terminals compatible with Pb-free SAC305 solder. It is designed for industrial power supplies and AC/DC conversion in instrumentation systems.
For engineers reviewing the VS-36MB100A datasheet, VS-36MB100A pinout, VS-36MB100A application, or VS-36MB100A equivalent, key selection criteria include thermal resistance (RthJC = 1.2 K/W), forward voltage drop (VFM = 1.14 V at 55 A pk), I²t rating (1130 A²s), isolation voltage (2700 V RMS), and mounting torque specification (2.0 Nm).
Technical Context
The VS-36MB100A implements a monolithic single-phase full-wave bridge configuration with four integrated diodes in a common insulated metal-base package. Its D-34 outline provides direct heatsink mounting via center hole and two fast-on terminals, enabling high-power dissipation with low thermal impedance.
It operates across -55 °C to +150 °C junction temperature range and supports both resistive/inductive (35 A) and capacitive (28 A) load conditions. The device meets industrial-level qualification and uses Sn/Ag/Cu solder with 260–275 °C reflow profile compatibility.

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 |
|---|---|---|---|
| VSKB3610 | Same 35 A / 1000 V rating but TO-247AC package; higher RthJC (1.5 K/W); no baseplate insulation | Requires external insulator and thermal pad; less suitable for direct heatsink mounting | Select when legacy TO-247 footprint compatibility is required and isolation can be managed externally |
| GBU10K | Lower 10 A rating, 1000 V VRRM, GBU package; RthJC = 3.0 K/W; no UL approval | Not rated for continuous 35 A operation; unsuitable for industrial ambient >60 °C without derating | Select only for low-power auxiliary supplies where size and cost outweigh thermal performance needs |
Compared with VSKB3610 and GBU10K, the VS-36MB100A delivers superior thermal performance (1.2 K/W), integrated electrical isolation, and UL certification - making it the preferred choice for high-reliability industrial AC/DC front-ends demanding direct heatsink integration and safety compliance.

FAQ
What is the maximum allowable case temperature for continuous operation of the VS-36MB100A?
The VS-36MB100A supports a maximum case temperature (TC) of 60 °C for its full 35 A average forward current rating under resistive or inductive load conditions. At higher case temperatures, derating is required per Figure 6 in the datasheet. This limit ensures safe junction temperature operation within the -55 °C to +150 °C range while maintaining reliability and lifetime.
Does the VS-36MB100A require an insulating washer when mounted to a grounded heatsink?
No, the VS-36MB100A does not require an insulating washer because its D-34 package features an electrically insulated metal baseplate. The isolation is rated for 2700 V RMS, allowing direct mounting to grounded heatsinks while maintaining safety and regulatory compliance - a key advantage over non-insulated alternatives like TO-247 rectifiers.
What is the forward voltage drop specification for the VS-36MB100A at rated current?
The VS-36MB100A has a maximum forward voltage drop (VFM) of 1.14 V at 55 A peak forward current and 25 °C junction temperature. This value reflects conduction loss under transient conditions; steady-state losses are lower due to thermal resistance and ambient conditions, and must be calculated using VF(TO)1 = 0.79 V and rt1 = 5.8 mΩ for design-level power loss estimation.
Can the VS-36MB100A be used with lead-free reflow soldering processes?
Yes, the VS-36MB100A is qualified for lead-free soldering using Sn/Ag/Cu (SAC305) alloy at peak temperatures between 260 °C and 275 °C. Its nickel-plated terminals ensure reliable wetting and intermetallic formation, and the encapsulation remains stable under standard reflow profiles - fully compliant with RoHS and IPC-J-STD-020 moisture sensitivity level (MSL) requirements.
How does the I²t rating of the VS-36MB100A affect fuse selection in the AC input line?
The VS-36MB100A has an I²t rating of 1130 A²s at 50 Hz, which defines its ability to withstand short-duration surge currents without failure. For proper coordination, the upstream fuse must have a lower I²t value - typically ≤ 700 A²s - to clear faults before the rectifier reaches thermal failure, ensuring selective protection in industrial power supply designs using the VS-36MB100A.
