Product details
Overview
VS-2KBB100 from Vishay Semiconductors is a single-phase silicon diode bridge rectifier rated for 1.9 A average DC output current at TC = 45 °C, with 1000 V maximum peak reverse voltage (VRRM), 1.1 V maximum forward voltage per diode at 1.9 A, and 500 A²s I²t rating at 10 ms (50 Hz). It is polarized, PCB-mountable on 2.54 mm grid, and used in AC/DC power supplies for industrial control panels.
For engineers reviewing the VS-2KBB100 datasheet, VS-2KBB100 pinout, VS-2KBB100 application, or VS-2KBB100 equivalent, key selection criteria include its 1000 V VRRM rating, 500 A surge current capability at 50 Hz, thermal derating behavior up to 150 °C junction temperature, and compatibility with capacitive loads up to 600 µF when paired with ≥5.0 Ω source resistance.
Technical Context
The VS-2KBB100 implements a standard full-wave single-phase bridge configuration with four monolithic silicon diodes in a molded plastic package. Its internal layout supports unidirectional DC output polarity with dedicated AC input terminals (~) and DC output terminals (+, –), enabling direct integration into off-line power conversion stages without external diode arrays.
It operates across 40–2000 Hz input frequency range and is characterized for both resistive/inductive and capacitive load conditions - with distinct IO ratings (1.9 A vs. 1.5 A) and defined minimum source resistance (5.0 Ω) to limit inrush surge in high-capacitance applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 1000 V - Maximum non-repetitive reverse voltage the bridge withstands without breakdown; defines safe AC input voltage ceiling (e.g., ≤707 V RMS). |
| IO (TC = 45 °C) | 1.9 A - Continuous DC output current under heatsink-limited thermal condition; sets max steady-state power delivery capability. |
| VFM per diode | 1.1 V @ 1.9 A - Forward voltage drop per conducting diode pair; determines conduction loss (≈2.2 V total bridge drop) and thermal dissipation. |
| IFSM (50 Hz) | 50 A - Non-repetitive surge current tolerance for one half-cycle; critical for handling cold-start inrush into bulk capacitance. |
| I²t (10 ms) | 17.7 A²s - Fusing energy threshold; used to coordinate upstream fuse selection to avoid nuisance blowing during transient surges. |
| TJ range | –40 to +150 °C - Operating junction temperature window; enables deployment in sealed enclosures or high-ambient industrial environments. |
| f range | 40–2000 Hz - Input frequency compatibility; supports line-frequency (50/60 Hz) and higher-frequency transformer-coupled or SMPS-derived inputs. |
Pinout & Package
VS-2KBB100 uses the standardized 2KBB plastic package: 19.0 mm × 17.0 mm × 18.0 mm (L × W × H), with 0.9 mm diameter leads spaced on 2.54 mm pitch. Polarized construction requires correct orientation during PCB placement.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| ~ (AC1) | AC input terminal 1 | One side of AC input winding; connected internally to anode of D1 and cathode of D2 in bridge topology. |
| ~ (AC2) | AC input terminal 2 | Other side of AC input winding; connected internally to cathode of D1 and anode of D2. |
| + | Positive DC output | Anode of output diode pair; delivers rectified positive voltage to filter capacitor and load. |
| – | Negative DC output / return | Cathode of output diode pair; serves as common reference and return path for DC load current. |
Key Features
| Feature | Design Value |
|---|---|
| Standard 2.54 mm lead pitch | Enables direct compatibility with through-hole PCB layouts using industry-standard 0.1" grid footprints and automated insertion equipment. |
| Polarized package marking | Clear "+" and "–" silkscreen plus diagonal corner notch ensures unambiguous orientation during manual or automated assembly. |
| High IFSM (50 A) | Supports reliable operation with large bulk input capacitors (e.g., 600 µF) without requiring oversized fusing or pre-charge circuitry. |
| Rated for 150 °C TJ | Allows sustained operation in thermally constrained environments such as enclosed motor drives or DIN-rail mounted PLC power modules. |
| Equivalent to DIN B500C1500 | Meets legacy European industrial standard for 1000 V bridge rectifiers, simplifying replacement in certified equipment. |

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 |
|---|---|---|---|
| GBU10K | Same 1000 V VRRM and 1.9 A IO, but GBU package (22.3 mm × 18.5 mm); 1.2 V VFM; 45 A IFSM. | Slightly lower surge rating and larger footprint; less suitable for space-constrained PCBs matching 2KBB outline. | Select GBU10K only if board layout accommodates larger body and higher forward drop is acceptable. |
| KBPC1010 | 1000 V VRRM, 10 A IO rating, but larger KBPC package (28.5 mm × 22.5 mm); 1.05 V VFM; 350 A IFSM. | Over-specified current capacity increases cost and size; intended for higher-power systems (>5 A loads). | Choose KBPC1010 only when future-proofing for load growth or when existing KBPC footprint is fixed. |
Compared with GBU10K and KBPC1010, the VS-2KBB100 offers optimal balance of compact 2KBB footprint, precise 1.9 A rating matching typical auxiliary supply needs, and 50 A surge capability - making it ideal for space- and cost-sensitive industrial control designs where exact current matching matters.

FAQ
What is the maximum continuous DC output current rating for VS-2KBB100?
The VS-2KBB100 is rated for 1.9 A average DC output current when case temperature (TC) is maintained at 45 °C with resistive or inductive loads. Under capacitive load conditions, the rating reduces to 1.5 A due to higher peak currents and thermal stress. This value is measured with proper heatsinking and must be derated above 45 °C per the datasheet's thermal curves.
Does VS-2KBB100 support 230 V AC mains input directly?
Yes, VS-2KBB100 supports 230 V AC mains input directly: its 1000 V VRRM rating provides a 2.5× safety margin over the 325 V peak of 230 V RMS, satisfying IEC 61000-4-5 surge immunity requirements. However, design must observe the 5.0 Ω minimum source resistance guideline when using ≥600 µF bulk capacitance to limit switch-on surge.
What is the pin configuration of VS-2KBB100 and how is polarity marked?
VS-2KBB100 has four terminals: two AC inputs labeled "~", one positive DC output "+", and one negative DC output "–". Polarity is marked via molded-in "+" and "–" symbols adjacent to respective leads, plus a diagonal corner notch on the package body indicating the "+" terminal side - ensuring correct orientation during PCB assembly.
Can VS-2KBB100 replace older DIN-standard B500C1500 rectifiers?
Yes, VS-2KBB100 is explicitly designated as equivalent to DIN B500C1500 per Vishay's cross-reference table. It matches the same 1000 V VRRM, 1.9 A IO, and mechanical footprint, allowing drop-in replacement in certified industrial equipment without redesign or requalification.
What is the operating temperature range and thermal resistance of VS-2KBB100?
VS-2KBB100 operates from –40 °C to +150 °C junction temperature. While the datasheet does not specify RθJC or RθJA values, its thermal performance is validated via derating curves showing allowable ambient temperature versus output current - e.g., 1.9 A is supported up to 45 °C ambient with no heatsink, assuming natural convection in free air.
