NRVBS260T3G-VF01 - 60V 2A SMB Schottky Rectifier | onsemi
MPN: NRVBS260T3G-VF01 ✓ Hoạt độngNRVBS260T3G-VF01 Tóm tắt
A Schottky barrier rectifier is a unipolar device that uses a metal-to-silicon junction rather than a PN junction. This construction eliminates minority carrier storage, which yields an ultra-low forward voltage drop (typically 0.5-0.7 V at moderate current) and extremely fast reverse recovery. The trade-off is higher leakage current and a lower reverse-voltage ceiling than PN-junction rectifiers, which is why 60 V-class Schottkys like the NRVBS260T3G dominate low-voltage, high-frequency power stages.
Key features include 60 V peak repetitive reverse voltage (VRRM = VRWM = VR), 2 A average rectified forward current at the rated VR, epitaxial construction with oxide passivation, metal overlay contact for low resistance, and a guard ring for transient protection. The SMB footprint supports compact PCB layouts and is compatible with standard SMD pick-and-place processes.
The NRVBS260T3G-VF01 uses an onsemi Schottky die designed for repetitive switching duty. Its low thermal resistance SMB package and 0.63 V max VF at 2 A minimize conduction losses, while the absence of reverse recovery charge eliminates switching loss in high-frequency freewheeling and OR-ing applications. This combination is why the part is a long-time workhorse in 12 V/24 V automotive and industrial power conversion.
Typical applications include low-voltage, high-frequency switching power supplies as output rectifiers; freewheeling diodes across inductive loads such as relay coils, motor windings, and solenoids; polarity-protection diodes at DC inputs; and OR-ing diodes in redundant power architectures. The 2 A current rating suits distributed 5 V and 12 V rails, while the 60 V standoff provides ample margin above 24 V industrial buses.
When designing with this part, place a Schottky in close proximity to the switching node to minimize the reverse-recovery loop. Parallel devices require careful thermal balancing, and the SMB package dissipates roughly 0.5 W per diode at 2 A continuous without a copper pour.

Ứng dụng tiêu biểu
NRVBS260T3G-VF01 phù hợp cho 7 Áp dụngs: Low-Voltage High-Frequency Switching Power Supply Output Rectifier, Freewheeling Diode Across Inductive Loads, Polarity Protection Diode at DC Input, OR-ing Diode in Redundant Power Architectures, Automotive 12 V / 24 V Bus Rectifier, Solar Panel Blocking Diode, USB / DC Connector Reverse-Current Block.
Low-Voltage High-Frequency Switching Power Supply Output Rectifier
The NRVBS260T3G-VF01 is well suited as the secondary-side output rectifier in 12 V and 24 V switching power supplies because its 60 V VRRM provides 2x headroom above 24 V rails, while the 0.63 V max VF at 2 A minimizes conduction loss. The absence of reverse-recovery charge eliminates switching loss at high converter frequencies (>=200 kHz), improving overall efficiency by 1-3% compared to PN-junction rectifiers. Place the diode in close proximity to the transformer/inductor secondary to minimize the reverse-recovery loop inductance.

Freewheeling Diode Across Inductive Loads
Use the NRVBS260T3G-VF01 as a freewheeling diode across relay coils, solenoids, motor windings, and small inductors in 12 V/24 V systems. The lack of reverse-recovery charge means the diode commutates cleanly when the switch opens, eliminating the high-voltage spike and EMI associated with PN-junction rectifiers. The 60 V reverse rating easily clamps the inductive kick of a 24 V coil, and the 2 A continuous rating handles inrush during contact closure.
Được đề xuất
Polarity Protection Diode at DC Input
Place the NRVBS260T3G-VF01 in series with the input of a 12 V or 24 V DC supply to protect downstream circuitry from reverse-battery or mis-wired connections. The 0.63 V forward drop at 2 A is acceptable in most 12 V systems (only ~5% loss at full load), and the 60 V VRRM easily survives load-dump transients up to 40 V typical in automotive environments. The SMB package handles the inrush current of bulk input capacitors on hot-plug events.
Được đề xuất
OR-ing Diode in Redundant Power Architectures
The NRVBS260T3G-VF01 enables low-loss OR-ing between two redundant 12 V or 24 V supplies in telecom, server, and industrial redundancy applications. The 0.63 V forward drop at 2 A is far lower than an ideal-diode MOSFET solution at this current level, and the lack of reverse recovery prevents cross-conduction between sources when one rail collapses. The 60 V reverse rating tolerates transient differences between supplies.

Automotive 12 V / 24 V Bus Rectifier
The NRVBS prefix indicates automotive qualification, making the NRVBS260T3G-VF01 ideal for body-electronics, lighting, and accessory modules operating directly off the 12 V automotive bus. Its 60 V reverse rating easily clamps load-dump transients per ISO 7637-2, while the 2 A rating handles accessory current loads up to ~1.5 A continuous with proper thermal management. The Pb-free SMB package meets automotive reflow and reliability requirements.

Solar Panel Blocking Diode
Use the NRVBS260T3G-VF01 as a low-loss blocking diode in small 12 V solar battery-charging panels to prevent reverse current flow from the battery back into the panel at night. Its 0.63 V forward drop is far lower than a silicon rectifier, preserving charging efficiency at low panel voltages, and its 60 V reverse rating tolerates open-circuit panel voltage on cold days. The 2 A rating matches typical small-panel short-circuit current.
Được đề xuất
USB / DC Connector Reverse-Current Block
Place the NRVBS260T3G-VF01 in series with a USB VBUS or DC barrel-jack rail to prevent reverse-current backfeeding when a device is plugged into two powered sources simultaneously. The 0.63 V drop is acceptable at 5 V/2 A USB levels (4.4% loss), and the SMB package fits in tight connector bays. The 60 V reverse rating provides ample margin for hot-plug transients.

Ghi chú thiết kế
At 2 A continuous forward current with VF = 0.63 V, the NRVBS260T3G-VF01 dissipates approximately 1.26 W of conduction loss. The SMB package has a typical thermal resistance of ~17 C/W junction-to-ambient on a 1 sq inch copper pad, producing an estimated ~21 C junction temperature rise above ambient. Estimated: P_D = VF x IO = 0.63 V x 2 A = 1.26 W; dT_J = 1.26 W x 17 C/W ~ 21 C. Provide adequate copper pour or thermal vias to keep the junction below 125 C at maximum rated ambient.
Place the Schottky as close as physically possible to the switching node (transformer secondary winding, inductor, or relay coil) to minimize the reverse-recovery loop inductance. Long traces between the diode and the switching element create voltage ringing that can exceed the 60 V VRRM rating and damage the part. Keep the diode footprint on a solid copper pour for thermal management and use short, wide traces for the high-current path.
Do not parallel multiple NRVBS260T3G-VF01 devices without ballast resistors or derating - Schottky diodes have positive temperature coefficient on forward voltage, which can lead to thermal runaway if one device hogs current. Do not exceed the 60 V reverse rating, including transient spikes from inductive loads; a TVS or snubber may be required in 24 V systems with long wire harnesses. Always verify the diode's reverse leakage at hot temperatures - Schottky leakage roughly doubles every 10 C, which can affect high-impedance circuits.
Use a standard SMB (DO-214AA) land pattern with the cathode pad marked clearly on the silkscreen. The recommended footprint per onsemi is approximately 2.5 mm x 2.0 mm pads with 1.0 mm gap, matching IPC-7352 nominal. Reflow profile should follow JEDEC J-STD-020 with peak temperature of 260 C for Pb-free assembly. The -VF01 suffix denotes 2,500-piece tape-and-reel packaging per EIA-481.
