Product details
Overview
SMB10J22AHE3/5B 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), 22 V stand-off voltage (VWM), and 35.5 V clamping voltage (VC) at 28.2 A peak pulse current. It is AEC-Q101 qualified and used to protect automotive sensor signal lines, MOSFET gates, and microcontroller I/O against inductive switching transients.
For engineers reviewing the SMB10J22AHE3/5B datasheet, SMB10J22AHE3/5B pinout, SMB10J22AHE3/5B application, or SMB10J22AHE3/5B equivalent, key selection criteria include unidirectional polarity, 22 V working voltage, 1000 W surge rating, AEC-Q101 qualification, and SMB package compatibility with automated SMT placement.
Technical Context
This TVS diode operates as a clamping device that remains non-conductive below 22 V and rapidly avalanches above its 24.4–26.9 V breakdown range (IT = 1 mA), limiting transient voltages to ≤35.5 V at 28.2 A. Its glass-passivated junction ensures stable leakage (<1 µA at VWM) and fast response time (<1 ns).
Thermal design relies on low RθJA (72 °C/W) and RθJL (20 °C/W), enabling reliable operation up to 150 °C junction temperature. The device meets MSL Level 1 (260 °C reflow peak) and is rated for 100 A non-repetitive forward surge (8.3 ms half-sine).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 22 V - Maximum continuous reverse operating voltage before clamping begins |
| VBR min/max | 24.4 V / 26.9 V - Breakdown occurs within this range at 1 mA test current, defining turn-on threshold |
| VC @ IPPM | 35.5 V - Clamped voltage during 28.2 A 10/1000 µs surge, limiting downstream IC stress |
| PPPM | 1000 W - Peak pulse power handling capability under standardized 10/1000 µs waveform |
| IPPM | 28.2 A - Maximum non-repetitive surge current the device safely clamps without failure |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ22A-E3/52 | Same VWM/VC/PPPM, but commercial-grade (non-AEC-Q101), RoHS-compliant only | Lacks automotive qualification; suitable for industrial/commercial designs without AEC requirements | Select when AEC-Q101 is not mandated and cost optimization is prioritized |
| SMCJ22AHE3/52 | Higher PPPM (1500 W), same VWM/VC, larger SMC (DO-214AB) package | Requires larger PCB footprint; better suited for higher-energy surge environments (e.g., 48 V systems) | Choose when system-level surge tests exceed 1000 W or when derating margin is critical |

FAQ
What is the clamping voltage of SMB10J22AHE3/5B at its rated peak pulse current?
The SMB10J22AHE3/5B has a maximum clamping voltage (VC) of 35.5 V when subjected to its rated peak pulse current (IPPM) of 28.2 A under the standard 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and ensures predictable overvoltage limiting for downstream circuitry. The SMB10J22AHE3/5B maintains this clamping performance across its specified operating temperature range.
Is SMB10J22AHE3/5B suitable for automotive applications?
Yes, SMB10J22AHE3/5B is AEC-Q101 qualified and explicitly designated for automotive use via its "HE3" suffix, confirming compliance with stress tests including temperature cycling, high-temperature reverse bias, and ESD. It is deployed in engine control units, ADAS sensor interfaces, and body electronics where transient immunity and long-term reliability are required. The SMB10J22AHE3/5B meets all applicable AEC-Q101 test conditions per Vishay documentation.
What does the "5B" in SMB10J22AHE3/5B indicate?
The "5B" suffix in SMB10J22AHE3/5B specifies the packaging configuration: 13-inch diameter plastic tape and reel, containing 3200 units per reel. This format supports high-volume automated assembly and is distinct from "52" (7-inch reel, 750 units) and "H/I" variants. The SMB10J22AHE3/5B reel meets EIA-481 standards and is compatible with standard SMT feeders.
How does SMB10J22AHE3/5B differ from bidirectional TVS diodes with similar voltage ratings?
The SMB10J22AHE3/5B is unidirectional and functions like a Zener diode in reverse bias, conducting only during negative transients relative to its cathode. Bidirectional variants (e.g., SMB8J22CA) conduct for both polarities and exhibit lower peak pulse power (800 W vs. 1000 W). The SMB10J22AHE3/5B offers superior surge handling for DC-biased lines such as automotive 12 V supplies or microcontroller I/O, where polarity is fixed and higher power absorption is needed.
What is the maximum junction temperature rating for SMB10J22AHE3/5B?
The SMB10J22AHE3/5B has a maximum junction temperature (TJ) rating of +150 °C, verified per its thermal characterization data. This enables operation in under-hood automotive environments and sealed industrial enclosures. Derating curves in the Vishay datasheet (Document 88422, Fig. 2) define allowable power reduction above 25 °C ambient, and the SMB10J22AHE3/5B maintains full 1000 W rating up to ~85 °C ambient with appropriate PCB copper area.
