Product details
Overview
VS-2KBB10R 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 100 V maximum peak reverse voltage (VRRM), 1.1 V maximum forward voltage per diode at 1.9 A, and 52 A non-repetitive surge current capability at 60 Hz. It is polarized, PCB-mountable on 2.54 mm grid, and used in AC/DC power supplies for consumer audio equipment.
For engineers reviewing the VS-2KBB10R datasheet, VS-2KBB10R pinout, VS-2KBB10R application, or VS-2KBB10R equivalent, key selection criteria include VRRM rating, IFSM surge margin, thermal derating for capacitive loads, and compatibility with DIN-standard board layouts.
Technical Context
This device integrates four silicon diodes in a single-phase full-wave bridge configuration, enabling AC-to-DC conversion without external wiring. Its polarized package enforces correct orientation during PCB assembly, and its 2KBB outline conforms to DIN mechanical standards for interchangeability with legacy B40C1500 parts.
Designed for operation across 40–2000 Hz input frequencies, it supports both resistive/inductive and capacitive loads-with derated IO = 1.5 A under capacitive conditions. Thermal performance is specified over TJ = –40 °C to +150 °C, with fusing I²t values of 16.1 A²s (8.3 ms) and 17.7 A²s (10 ms) at initial TJ = 150 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Maximum peak reverse voltage per diode; defines safe AC input limit before breakdown |
| IO (TC = 45 °C) | 1.9 A - Continuous DC output current with heatsink at 45 °C ambient; derates to 1.5 A for capacitive loads |
| VFM (per diode) | 1.1 V @ 1.9 A - Forward voltage drop determining conduction loss and thermal load in rectifier stage |
| IFSM (60 Hz) | 52 A - Non-repetitive surge current tolerance; critical for inrush handling in transformer-coupled supplies |
| I²t (8.3 ms) | 16.1 A²s - Fusing energy threshold; used to coordinate with upstream fuse selection for short-circuit protection |
| TJ Range | –40 °C to +150 °C - Operating junction temperature range; enables use in enclosed industrial enclosures |
| f Range | 40–2000 Hz - Input frequency compatibility; supports line-frequency and high-frequency switch-mode inputs |
Pinout & Package
The VS-2KBB10R uses the standard 2KBB plastic package (19.0 × 14.5 × 7.0 mm), polarized with molded "+" and "~" markings. Leads are spaced on 2.54 mm (0.1") grid for through-hole PCB mounting.
| 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 |
| ~ (AC2) | AC input terminal 2 | Other side of AC input winding; connected internally to anode of D3 and cathode of D4 |
| + | DC positive output | Common cathode node of D1 and D3; delivers rectified positive voltage |
| – | DC negative output | Common anode node of D2 and D4; serves as return path and ground reference |
Key Features
| Feature | Design Value |
|---|---|
| Polarized PCB footprint | Molded "+" and "~" markings prevent incorrect orientation during manual or automated assembly |
| DIN-equivalent mechanical form | 2KBB outline matches B40C1500 standard-enables drop-in replacement in legacy industrial designs |
| High surge current capability | 52 A IFSM at 60 Hz allows reliable operation with transformer inrush and motor-start transients |
| Capacitive load derating support | Specified IO = 1.5 A at TC = 45 °C for capacitor-input filters-enables accurate thermal design |

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 |
|---|---|---|---|
| GBU4K | Same 1.9 A IO and 100 V VRRM, but GBU package (22.5 × 18.5 × 4.5 mm) has taller profile and different lead spacing (5.08 mm) | Requires PCB footprint redesign; higher thermal resistance due to smaller copper pad area | Select when existing GBU socket or thermal pad layout exists; not suitable for space-constrained 2KBB footprints |
| DB101 | Lower VRRM = 50 V; same 1.9 A IO and 2KBB-compatible outline but no polarization marking | Limited to ≤35 VAC input; increased risk of misorientation during hand-soldering | Acceptable only where input voltage is strictly limited and assembly process includes polarity verification step |
Compared with GBU4K and DB101, VS-2KBB10R uniquely combines DIN-standard 2KBB mechanical compatibility, explicit polarization, and 100 V VRRM in a compact 19.0 × 14.5 mm footprint-making it optimal for retrofitting legacy B40C1500-based designs without layout change.

FAQ
What is the maximum allowable ambient temperature for VS-2KBB10R at full 1.9 A load?
The VS-2KBB10R delivers 1.9 A average DC output current only when case temperature (TC) is maintained at 45 °C. Ambient temperature must be significantly lower-typically ≤40 °C with adequate PCB copper area-to achieve this condition. Derating curves in Figure 1 show usable current drops to ~1.2 A at 70 °C ambient for resistive loads.
Does VS-2KBB10R support capacitor-input filter configurations?
Yes, VS-2KBB10R supports capacitor-input filters but with reduced current rating: IO = 1.5 A at TC = 45 °C. This derating accounts for higher peak currents and thermal stress caused by charging large bulk capacitors. Minimum source resistance requirements (RMIN) are specified in Figure 3 to limit inrush.
What does the "R" suffix in VS-2KBB10R indicate?
The "R" suffix denotes the standard pin configuration: AC terminals marked "~ ~", DC positive marked "+", and DC negative marked "–". This matches the polarized 2KBB outline shown in Document 95328 and distinguishes it from non-polarized variants. All VS-2KBBxR parts share this marking convention.
How does VS-2KBB10R compare to VS-2KBB05R in terms of surge capability?
VS-2KBB10R and VS-2KBB05R share identical IFSM = 52 A (60 Hz) and I²t = 16.1 A²s (8.3 ms), as surge ratings are determined by internal die construction-not VRRM. The difference lies in reverse voltage capability: VS-2KBB05R is rated for 50 V VRRM, while VS-2KBB10R supports 100 V.
Is VS-2KBB10R RoHS-compliant and halogen-free?
Yes, VS-2KBB10R complies with RoHS Directive 2011/65/EU and is halogen-free per Vishay specification 99912. Material categorization data confirms exemption status for lead in glass encapsulation and compliance with JEDEC J-STD-609 for marking.
