Product details
Overview
VSIB2020-E3/45 from Vishay General Semiconductor is a single-phase, single in-line bridge rectifier with 20 A average forward current (IF(AV)), 200 V maximum repetitive peak reverse voltage (VRRM), and 240 A peak forward surge current (IFSM). It features glass-passivated junctions, 2500 VRMS case dielectric strength, and is housed in the GSIB-5S package for high-reliability ac-to-dc full-wave rectification in switching power supplies.
For engineers reviewing the VSIB2020-E3/45 datasheet, VSIB2020-E3/45 pinout, VSIB2020-E3/45 application, or VSIB2020-E3/45 equivalent, this part delivers verified thermal performance (RθJC = 1.5 °C/W), RoHS-compliant matte tin-plated leads, JESD201 Class 1A whisker resistance, and UL E54214 recognition - critical for industrial and consumer-grade power conversion designs requiring stable thermal derating and regulatory compliance.
Technical Context
This discrete bridge rectifier integrates four silicon diodes in a single GSIB-5S molded package with internal common-cathode and common-anode configuration. Its glass-passivated chip junction ensures stable reverse leakage (IR ≤ 10 µA at 25 °C) and robust surge handling (IFSM = 240 A, I²t = 240 A²s).
Designed for bolt-down heatsink mounting (max torque 10 cm·kg), it achieves 20 A IF(AV) only when case temperature (TC) is maintained at 87 °C - not ambient - and drops to 3.5 A under PCB-only conditions (TA = 25 °C), reflecting its thermal-path-dependent rating architecture.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IF(AV) | 20 A at TC = 87 °C - requires aluminum plate heatsink mounting for full-rated output current |
| VRRM | 200 V - maximum non-repetitive reverse voltage per diode leg before breakdown |
| IFSM | 240 A - withstands single half-sine surge up to 8.3 ms without failure |
| VF | 1.0 V at 10 A - low forward drop enables efficient power conversion in 50/60 Hz and SMPS front-ends |
| IR | 10 µA at 25 °C - minimal leakage preserves efficiency in high-impedance hold-up circuits |
| RθJC | 1.5 °C/W - thermal resistance from junction to case confirms suitability for forced-convection heatsinking |
| TJ max. | 150 °C - maximum allowable junction temperature defines safe operating area under transient load |
Pinout & Package
Package: GSIB-5S - 5-terminal single in-line molded epoxy case (UL 94 V-0), 30 mm length, 11 mm width, 20 mm height, with center mounting hole and solderable matte tin-plated leads.

| – (Cathode Common) | Negative DC output | Internal connection point of all cathodes; serves as rectified return/reference node |
| Mounting Tab | Thermal & mechanical ground | Electrically isolated metal tab for heatsink attachment; not electrically connected to any semiconductor terminal |
Key Features
| Feature | Design Value |
|---|---|
| UL E54214 recognition | Validated safety certification for end-equipment compliance in North America |
| Glass-passivated junction | Enhanced moisture and contamination resistance for long-term reliability in humid environments |
| 2500 VRMS case dielectric strength | Ensures isolation integrity between AC inputs and DC outputs under transient overvoltage stress |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bridge rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| GBU20K-E3/45 | Same 20 A IF(AV) and 200 V VRRM, but GBU package (larger footprint, higher RθJA = 30 °C/W) | Less effective heatsinking in space-constrained layouts; requires larger PCB cutout | Choose if legacy GBU footprint compatibility is required and thermal margin allows higher RθJA |
| GBJ2002-E3/45 | 20 A IF(AV), 200 V VRRM, but GBJ package with lower IFSM (180 A vs. 240 A) and no UL recognition | Not suitable for safety-critical or certified end equipment requiring UL file validation | Choose only for cost-sensitive, non-certified industrial controls where surge margin is relaxed |
Compared with GBU20K-E3/45 and GBJ2002-E3/45, VSIB2020-E3/45 offers superior thermal transfer (RθJC = 1.5 °C/W), UL E54214 listing, and 240 A surge capability - making it the preferred choice for certified, high-reliability, heatsink-mounted bridge rectification where board space and safety compliance are prioritized.

FAQ
What is the maximum average forward current rating for VSIB2020-E3/45 and under what conditions?
The VSIB2020-E3/45 has a maximum average forward rectified output current (IF(AV)) of 20 A, but only when mounted on an aluminum plate heatsink at case temperature (TC) of 87 °C. Under PCB-only mounting at ambient temperature (TA = 25 °C), the rating drops to 3.5 A. This thermal dependency must be validated using the derating curve in Figure 1 of the datasheet.
Does VSIB2020-E3/45 have UL safety certification?
Yes, VSIB2020-E3/45 carries UL recognition under file number E54214, confirming compliance with UL/CSA safety standards for use in end equipment requiring certified rectification components. This applies specifically to the E3 suffix variant and is documented in Vishay document 84654.
What is the thermal resistance from junction to case (RθJC) for VSIB2020-E3/45?
The VSIB2020-E3/45 has a typical junction-to-case thermal resistance (RθJC) of 1.5 °C/W, measured with the device bolted to an aluminum heatsink using silicone thermal compound. This value is critical for calculating junction temperature rise under load and is specified in the Thermal Characteristics table of the datasheet.
Is VSIB2020-E3/45 compliant with RoHS and lead-free soldering requirements?
Yes, VSIB2020-E3/45 meets RoHS Directive 2011/65/EU and is compatible with lead-free soldering processes, including solder dip at 260 °C for 40 seconds. Its matte tin-plated leads comply with J-STD-002 and JESD22-B102, and the E3 suffix indicates JESD201 Class 1A whisker resistance.
What is the peak forward surge current (IFSM) rating for VSIB2020-E3/45?
The VSIB2020-E3/45 is rated for a non-repetitive peak forward surge current (IFSM) of 240 A, tested with a single half-sine waveform at 60 Hz. This rating reflects its ability to survive inrush currents during cold startup of capacitive-input power supplies without degradation.
