Diodes Incorporated SBR02U100LPQ-7B

Overview

SBR02U100LPQ-7B from Diodes Incorporated is a 100 V, 250 mA surface-mount Super Barrier Rectifier (SBR®) with ultra-low forward voltage (0.72 V @ 200 mA, +25°C), soft fast switching (3.6 ns reverse recovery), and AEC-Q101 qualification for automotive use. It serves as a low-loss blocking diode in DC-DC converter outputs and low-voltage AC-DC rectification stages where thermal efficiency and reliability at +150°C junction temperature are critical.

For engineers reviewing the SBR02U100LPQ-7B datasheet, SBR02U100LPQ-7B pinout, SBR02U100LPQ-7B application, or SBR02U100LPQ-7B equivalent, key selection criteria include its 0.76 V max VF at 200 mA/+25°C, 1.0 µA max IR at 75 V/+25°C, 5 A non-repetitive surge rating, 100 V VRRM, and X1-DFN1006-2 package compatibility with space-constrained automotive and portable power designs.

Technical Context

This Super Barrier Rectifier employs Diodes' patented SBR® technology to achieve lower forward voltage than Schottky diodes while maintaining superior reverse avalanche ruggedness and higher temperature capability than standard PN junction rectifiers. Its soft recovery characteristic minimizes EMI in high-frequency switching converters.

The device operates up to +150°C junction temperature and is qualified per AEC-Q101 with PPAP support, manufactured in IATF 16949-certified facilities. Its 80 pF capacitance at 0 V and 1 MHz enables stable performance in high-speed output rectification without excessive ringing.

FAQ

What is the cathode identification method for SBR02U100LPQ-7B?

The cathode is marked by a bar on the top surface of the X1-DFN1006-2 package. This contrasts with the dot-marked SBRT02U100LPQ-7 variant. The bar aligns with industry-standard optical recognition algorithms used in high-speed SMT placement equipment and is verified in Diodes' package outline DS38511 Rev. 2–2, page 5.

Is SBR02U100LPQ-7B suitable for synchronous rectification replacement?

No-it is a unidirectional rectifier, not a synchronous MOSFET driver or integrated controller. However, its 3.6 ns tRR and soft recovery make it an optimal *asynchronous* replacement for Schottky diodes in flyback or buck converters where gate drive complexity must be avoided and EMI must be minimized.

Does SBR02U100LPQ-7B require derating at elevated ambient temperatures?

Yes. At TA = +85°C, the average rectified current IO must be reduced to ~180 mA per Figure 1 in DS38511, due to thermal resistance limitations. Derating follows the published thermal curve: IO drops linearly from 250 mA at +25°C to ~120 mA at +125°C ambient on FR-4 PCB with recommended pad layout.

Can SBR02U100LPQ-7B be used in reverse-biased Zener-like clamp configurations?

No. It is not characterized or rated for controlled reverse breakdown. Its reverse breakdown voltage is guaranteed minimum 100 V (V(BR)R ≥ 100 V at IR = 1 mA), with no specified Zener knee or power dissipation rating in reverse bias-using it as a clamp risks uncontrolled avalanche and permanent damage.
