Product details
Overview
LVB1560-M3/45 from Vishay General Semiconductor is a low forward voltage, single-phase, single in-line bridge rectifier rated for 15 A average forward current and 600 V peak reverse voltage, with 400 A surge capability and 2500 VRMS dielectric strength; it is used in telecom power supplies, high-efficiency desktop/server SMPS, and white-goods AC/DC conversion.
For engineers reviewing the LVB1560-M3/45 datasheet, LVB1560-M3/45 pinout, LVB1560-M3/45 application, or LVB1560-M3/45 equivalent, key selection criteria include thermal resistance (RθJC = 1.0 °C/W), low VF at 7.5 A (0.73 V @ 125 °C), IEC 61000-4-5 surge immunity (6 kV), GSIB-5S package compatibility, and halogen-free RoHS-compliant construction.
Technical Context
This device implements a four-diode full-wave bridge configuration in a compact GSIB-5S single in-line package with oxide planar junctions, enabling high surge robustness and stable operation up to 150 °C junction temperature. Its 1.8 μs typical reverse recovery time and 260 pF junction capacitance support efficient switching in high-frequency SMPS designs.
The LVB1560-M3/45 delivers 15 A average output current when mounted on an aluminum heatsink (TC = 125 °C), but derates to 3.6 A in free-air mounting (TA = 25 °C); its 664 A²s I²t rating ensures fuse coordination under transient overloads without catastrophic failure.

Equivalent & Alternatives
The following parts are listed as comparable options for similar bridge rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| VBU1560-M3/45 | Same GSIB-5S package, identical VRRM/IF(AV)/IFSM ratings, but higher VF (0.82 V @ 7.5 A, 125 °C). | Slightly lower efficiency in thermally limited designs; acceptable where cost sensitivity outweighs 50–100 mW per diode loss. | Select when legacy design validation exists for VBU1560-M3/45 and minor VF increase is acceptable. |
| GBU1560 | GBU package (larger, through-hole), same 600 V/15 A rating, but RθJC = 1.5 °C/W and no IEC 61000-4-5 certification. | Requires larger PCB area and external heatsinking; unsuitable for space-constrained telecom/server applications needing surge immunity. | Choose only for cost-driven, non-surge-critical industrial controls where GBU footprint is already established. |
Compared with VBU1560-M3/45 and GBU1560, the LVB1560-M3/45 offers superior thermal performance (RθJC = 1.0 °C/W), lower conduction loss (0.73 V), and certified 6 kV surge immunity-making it optimal for high-density, high-reliability telecom and server power supplies where efficiency and transient robustness are critical.

FAQ
What is the maximum junction temperature rating for the LVB1560-M3/45?
The LVB1560-M3/45 has a maximum junction temperature (TJ max.) of +150 °C, verified per JEDEC test conditions. This rating enables reliable operation in high-ambient environments such as enclosed server PSUs or telecom rectifier cabinets. Derating curves in the datasheet define safe current limits at elevated temperatures, and thermal design must maintain TJ ≤ 150 °C using appropriate heatsinking or airflow. The LVB1560-M3/45 achieves this limit while sustaining 15 A average current when TC = 125 °C.
Does the LVB1560-M3/45 meet UL safety certification?
Yes, the LVB1560-M3/45 carries UL recognition under file number E54214, Vol. 1, confirming compliance with UL 60747-4 for semiconductor devices. This certification covers dielectric strength (2500 VRMS, 1 minute), flammability (UL 94 V-0 epoxy), and construction integrity. It supports end-equipment safety approvals for Class I and II appliances, telecom infrastructure, and industrial power supplies. The LVB1560-M3/45's UL listing is explicitly stated in the Vishay datasheet revision 21-Jun-2022 (Doc. #89392).
What is the reverse recovery time (trr) of the LVB1560-M3/45, and how does it affect switching performance?
The LVB1560-M3/45 has a typical reverse recovery time (trr) of 1.8 μs, measured at IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A. This fast recovery minimizes switching losses and associated EMI in high-frequency bridge rectification circuits, especially in PFC and resonant topologies operating above 50 kHz. Compared to standard recovery bridges (>3 μs), the LVB1560-M3/45 reduces turn-off energy and improves overall efficiency. The LVB1560-M3/45's trr is stable across temperature and contributes to its suitability in high-efficiency server SMPS designs.
Can the LVB1560-M3/45 be mounted directly to a heatsink, and what is the recommended torque?
Yes, the LVB1560-M3/45 features an electrically isolated metal tab designed for direct heatsink mounting. The recommended mounting torque is 5.7 cm-kg (5 in-lbs), with a maximum of 10 cm-kg (8.8 in-lbs). Exceeding this torque risks cracking the epoxy case or damaging internal wire bonds. Thermal interface material should be applied between the tab and heatsink to minimize RθJC, which is specified at 1.0 °C/W under proper mounting conditions. The LVB1560-M3/45's thermal performance depends critically on correct mechanical installation per Vishay's mechanical data sheet.
Is the LVB1560-M3/45 compatible with lead-free reflow soldering processes?
The LVB1560-M3/45 is qualified for lead-free soldering per JESD 22-B106: maximum solder dip temperature is 275 °C for 10 seconds. Its matte tin-plated leads comply with J-STD-002 and JESD 22-B102 for solderability. While rated for wave soldering, it is not intended for standard Pb-free reflow profiles (peak > 260 °C), as the GSIB-5S package lacks reflow qualification data. For SMT assembly, verify process compatibility with Vishay's latest packaging bulletin. The LVB1560-M3/45 is supplied in tube packaging (code "45") and is optimized for through-hole mounting.
