Product details
Overview
SMB10J28AHE3_B/H from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, designed for high-energy surge protection with 1000 W peak pulse power (10/1000 µs), 28 V stand-off voltage (VWM), and 45.4 V clamping voltage (VC) at 22.0 A peak pulse current. It serves as primary overvoltage protection for automotive power rails and signal lines in engine control units and ADAS sensors.
For engineers reviewing the SMB10J28AHE3_B/H datasheet, SMB10J28AHE3_B/H pinout, SMB10J28AHE3_B/H application, or SMB10J28AHE3_B/H equivalent, this part is selected for AEC-Q101 qualified 28 V systems requiring low-leakage (<1.0 µA), fast-response (<1 ns), and robust 100 A IFSM surge handling in space-constrained surface-mount designs.
Technical Context
This TVS diode operates as a clamping device triggered by reverse-biased avalanche breakdown above its 31.1–34.4 V breakdown voltage (VBR) at 1 mA test current. Its glass-passivated junction ensures stable leakage and long-term reliability under thermal cycling between –55 °C and +150 °C.
The SMB10J28AHE3_B/H delivers 1000 W peak pulse power with low incremental surge resistance and meets MSL level 1 per J-STD-020 (260 °C reflow peak). Its matte tin-plated leads comply with J-STD-002 and JESD 22-B102 solderability standards and JESD 201 Class 2 whisker resistance.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ28A-E3/52 | Same VWM (28 V), VC (45.4 V), and PPPM (1000 W); commercial-grade, non-AEC-Q101 | Lacks automotive qualification; unsuitable for safety-critical or OEM production | Select when cost sensitivity outweighs automotive compliance requirements |
| 1.5SMC28AHE3_A/H | Higher package thermal resistance (RθJA = 11°C/W vs. 72°C/W), same electrical specs | SMC package occupies ~2.5× PCB area; less suitable for dense automotive layouts | Choose only if existing SMC footprint must be retained and space permits |
Compared with SMBJ28A-E3/52 and 1.5SMC28AHE3_A/H, the SMB10J28AHE3_B/H uniquely combines AEC-Q101 qualification, SMB footprint efficiency, and verified 100 A IFSM performance-making it the preferred choice for new automotive designs where reliability, size, and surge margin are jointly constrained.

FAQ
What is the clamping voltage of SMB10J28AHE3_B/H at its rated peak pulse current?
The SMB10J28AHE3_B/H has a maximum clamping voltage (VC) of 45.4 V when subjected to its rated peak pulse current (IPPM) of 22.0 A under the standard 10/1000 µs waveform. This value is measured at TA = 25 °C and defines the upper voltage limit imposed on protected circuitry during surge events. The SMB10J28AHE3_B/H maintains this clamping performance across its full operating temperature range.
Is SMB10J28AHE3_B/H qualified for automotive use?
Yes, SMB10J28AHE3_B/H is AEC-Q101 qualified, as confirmed by Vishay's documentation and ordering code suffix "HE3". This qualification covers stress tests including temperature cycling, high-temperature operating life, and unbiased highly accelerated stress testing-ensuring suitability for under-hood and cabin automotive applications such as engine control units and body control modules.
What does the "_B/H" suffix in SMB10J28AHE3_B/H indicate?
Per Vishay's ordering information, the "_B/H" suffix denotes packaging: "H" specifies 7-inch plastic tape-and-reel with 750 units per reel, while "B" indicates the revision level of the manufacturing process or test flow. This format aligns with Vishay's standard automotive-grade packaging nomenclature and confirms RoHS compliance and AEC-Q101 qualification for the SMB10J28AHE3_B/H unit.
How does SMB10J28AHE3_B/H differ from SMBJ28A in terms of surge capability?
The SMB10J28AHE3_B/H and SMBJ28A share identical electrical ratings-including VWM (28 V), VBR (31.1–34.4 V), VC (45.4 V), and PPPM (1000 W)-but differ in qualification: SMB10J28AHE3_B/H is AEC-Q101 qualified and built to automotive process controls, whereas SMBJ28A is commercial-grade. Both meet MSL Level 1, but only SMB10J28AHE3_B/H is approved for OEM automotive production.
What is the maximum operating junction temperature for SMB10J28AHE3_B/H?
The SMB10J28AHE3_B/H has a maximum operating junction temperature (TJ max) of +150 °C, enabling reliable operation in high-temperature automotive environments such as engine compartments and powertrain control units. This rating is validated per Vishay's thermal characteristics data and supports continuous operation up to ambient temperatures of +125 °C when mounted on recommended 0.2" × 0.2" copper pads.
