It delivers low power loss and high efficiency in DC/DC converters and polarity protection circuits.
For engineers reviewing the SBLB1630CTHE3/45 datasheet, SBLB1630CTHE3/45 pinout, SBLB1630CTHE3/45 application, or SBLB1630CTHE3/45 equivalent, this AEC-Q101 qualified, RoHS-compliant dual Schottky rectifier supports high-frequency switching mode power supplies with verified thermal resistance of 2.0 °C/W per diode and 250 A peak surge capability.
Technical Context
This dual-diode device integrates two independent Schottky junctions sharing a common cathode terminal (Pin 2), enabling compact half-wave or full-wave synchronous rectification topologies. Its guardring structure provides overvoltage protection, and its low VF enables high-efficiency operation at switching frequencies up to several MHz.
The TO-263AB package features a heatsink-connected anode tab (Pin 1) and isolated cathode (Pin 2), supporting surface-mount assembly with 275 °C solder bath tolerance and J-STD-020 MSL Level 1 rating. Thermal resistance from junction to case is 2.0 °C/W per diode, validated at TC = 25 °C.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay SBLB1640CTHE3/45 | Higher VRRM (40 V) but identical package, pinout, and thermal specs; VF = 0.60 V @ 8 A | Preferred where 36 V transients or higher bus voltages occur; slightly lower efficiency at 12 V outputs | Select when system requires 40 V blocking margin without layout change |
| ON Semiconductor NSR20F30HT1G | Single-diode SOD-123FL package; 30 V VRRM, 2 A IF(AV); VF = 0.45 V @ 2 A | Not pin-compatible; suitable only for low-current, space-constrained designs-not a drop-in replacement | Consider only for new designs with <2 A per diode requirement and PCB area constraints |

FAQ
What is the maximum junction temperature rating for the SBLB1630CTHE3/45?
The SBLB1630CTHE3/45 has a maximum junction temperature (TJ max.) of +125 °C, as specified in the Vishay datasheet Document Number 88727. This rating applies across the full operating range and is used to define derating curves for forward current versus case temperature. Engineers must ensure thermal design keeps actual TJ ≤ 125 °C under worst-case load and ambient conditions to maintain reliability and AEC-Q101 compliance.
Is the SBLB1630CTHE3/45 pin-compatible with other variants in the SBL(F,B)16xxCT family?
Yes-the SBLB1630CTHE3/45 shares identical TO-263AB pinout (Pin 1 = Anode 1, Pin 2 = Common Cathode, Pin 3 = Anode 2) with all SBLB16xxCT variants, including SBLB1640CTHE3/45. Mechanical and electrical pin assignments are fully consistent across the SBLB subfamily, enabling direct substitution where voltage and current ratings align with design requirements.
Does the SBLB1630CTHE3/45 meet automotive qualification standards?
Yes-the SBLB1630CTHE3/45 is explicitly AEC-Q101 qualified, as confirmed in the Vishay datasheet revision 27-Jun-12 (Document Number 88727). The HE3 suffix denotes AEC-Q101 qualification, covering stress tests including temperature cycling, high-temperature reverse bias, and ESD. This makes SBLB1630CTHE3/45 suitable for under-hood and infotainment applications requiring automotive-grade reliability.
What is the thermal resistance from junction to case for the SBLB1630CTHE3/45?
The typical thermal resistance from junction to case (RθJC) for the SBLB1630CTHE3/45 is 2.0 °C/W per diode, measured at TC = 25 °C. This value is specific to the TO-263AB package and enables accurate heatsink sizing when the device operates at its rated 8 A per diode. The datasheet confirms identical RθJC for all SBLB16xxCT variants in this package.
Can the SBLB1630CTHE3/45 be used in high-frequency switching applications?
Yes-the SBLB1630CTHE3/45 is designed for high-frequency operation, as stated in its "FEATURES" section. Its Schottky construction eliminates minority-carrier storage delay, enabling clean commutation at frequencies exceeding 1 MHz. Application notes and characteristic curves (e.g., Fig. 3–4 in Document 88727) confirm stable VF and IR behavior under fast-switching conditions typical of modern DC/DC converters.
