Product details
Overview
2KBP02M-E4/51 from Vishay General Semiconductor is a glass passivated single-phase bridge rectifier with 200 V maximum repetitive peak reverse voltage (VRRM), 2 A average forward output current (IF(AV)), and 60 A peak forward surge current (IFSM). It features 1.1 V forward voltage drop at 3.14 A, 5 µA reverse leakage at 25 °C, and operates from −55 °C to +165 °C junction temperature. It is used in AC-to-DC full-wave rectification for switching power supplies.
For engineers reviewing the 2KBP02M-E4/51 datasheet, 2KBP02M-E4/51 pinout, 2KBP02M-E4/51 application, or 2KBP02M-E4/51 equivalent, key selection criteria include VRRM rating, thermal resistance (RθJA = 30 °C/W), PCB-mountable KBPM package, RoHS compliance, and UL recognition (E54214) for safety-critical consumer-grade designs.
Technical Context
This device integrates four silicon diodes in a single-phase full-wave bridge configuration, enabling efficient AC input conversion to unidirectional DC output without external wiring. Its glass passivation ensures stable reverse characteristics and high dielectric strength across temperature extremes.
The KBPM case uses silver-plated leads compliant with J-STD-002 and JESD22-B102, supporting solder dip at 260 °C for 40 s. Polarity is marked on the body with positive lead indicated by beveled corner, and epoxy meets UL 94V-0 flammability rating.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - Maximum repetitive reverse voltage the bridge withstands without breakdown; defines AC input voltage limit (e.g., ≤141 V RMS). |
| IF(AV) | 2.0 A at TA = 55 °C - Continuous DC output current capability under standard PCB mounting conditions. |
| IFSM | 60 A - Peak non-repetitive surge current per diode; supports inrush handling in SMPS startup. |
| VF | 1.1 V at 3.14 A - Forward voltage drop per diode; determines conduction loss and thermal load at rated current. |
| IR | 5 µA at 25 °C - Reverse leakage per diode; critical for low-power standby efficiency and voltage hold-up stability. |
| TJ max. | +165 °C - Maximum junction temperature; enables operation in compact, thermally constrained enclosures. |
| RθJA | 30 °C/W - Thermal resistance from junction to ambient on PCB with 12 × 12 mm copper pads; guides heatsinking requirements. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bridge rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| GBU2K-E4/51 | VRRM = 200 V, IF(AV) = 2 A, same KBPM package, but higher VF (1.15 V typical) and lower IFSM (50 A). | Lower surge margin may require derating in high-inrush applications; identical PCB footprint. | Select when cost sensitivity outweighs surge headroom needs and thermal budget allows slightly higher conduction loss. |
| W02M-E4/51 | VRRM = 200 V, IF(AV) = 1.5 A, smaller WOB package (0.470 × 0.320"), RθJA = 40 °C/W, VF = 1.1 V. | Lower current rating and higher thermal resistance limit use to <1.2 A continuous loads or forced-air-cooled designs. | Choose for space-constrained layouts where 2 A rating is not required and board area is premium. |
Compared with GBU2K-E4/51 and W02M-E4/51, the 2KBP02M-E4/51 offers superior surge robustness (60 A vs. 50 A/-) and thermal performance (RθJA = 30 °C/W vs. 30/40 °C/W), making it optimal for high-reliability, thermally demanding consumer power supplies.

FAQ
What is the maximum operating temperature for 2KBP02M-E4/51?
The 2KBP02M-E4/51 has a specified operating junction temperature range of −55 °C to +165 °C. This allows reliable operation in sealed or high-ambient environments such as enclosed power adapters or appliance control modules. The 165 °C maximum enables design margin above typical 125 °C limits, reducing thermal derating needs in compact layouts. Always verify actual TJ using RθJA = 30 °C/W and measured ambient conditions.
Is 2KBP02M-E4/51 RoHS and REACH compliant?
Yes, 2KBP02M-E4/51 complies with RoHS Directive 2011/65/EU and WEEE 2002/96/EC, as confirmed in Vishay document 88532. It contains no lead, mercury, cadmium, hexavalent chromium, PBB, or PBDE above threshold limits. The "E4" suffix explicitly denotes consumer-grade RoHS-compliant construction, and the epoxy meets UL 94V-0 flammability requirements.
What does the "/51" suffix mean in 2KBP02M-E4/51?
The "/51" suffix in 2KBP02M-E4/51 indicates packaging in anti-static PVC trays containing 600 units per tray. This differs from "/45", which denotes tube packaging (30 units). The /51 format supports automated SMT placement and ESD-safe handling in high-volume manufacturing. Both /45 and /51 share identical electrical and thermal specifications for the 2KBP02M-E4/51 device.
Can 2KBP02M-E4/51 replace 2KBP01M-E4/51 in a design?
Yes, 2KBP02M-E4/51 can directly replace 2KBP01M-E4/51 because both share identical package (KBPM), pinout, thermal characteristics, and forward voltage (1.1 V), differing only in VRRM (200 V vs. 100 V). Upgrading to 2KBP02M-E4/51 provides enhanced reverse voltage margin for 230 VAC applications or designs requiring extended safety margins without layout changes.
What is the typical junction capacitance of 2KBP02M-E4/51?
The typical junction capacitance (CJ) of 2KBP02M-E4/51 is 25 pF per diode, measured at 4.0 V reverse bias and 1 MHz. This value influences high-frequency noise coupling and EMI filter design in switching power supplies. Lower CJ reduces capacitive feedthrough of switching transients, supporting cleaner DC output and simplified EMI mitigation compared to higher-CJ alternatives.
