Product details
Overview
SMB10J5.0AHE3/52 from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, designed for high-energy surge protection on 5.0 V DC power rails and signal lines. It delivers 1000 W peak pulse power (10/1000 µs), clamps transients to ≤9.2 V at 108.7 A, and features AEC-Q101 qualification for automotive electronics.
For engineers reviewing the SMB10J5.0AHE3/52 datasheet, SMB10J5.0AHE3/52 pinout, SMB10J5.0AHE3/52 application, or SMB10J5.0AHE3/52 equivalent, key selection criteria include stand-off voltage (5.0 V), clamping voltage (9.2 V), peak pulse current (108.7 A), AEC-Q101 qualification, and SMB package compatibility with automated SMT assembly.
Technical Context
This TVS diode operates as a voltage-clamped crowbar device triggered by reverse-biased avalanche breakdown above its 6.4–7.07 V breakdown range. Its glass-passivated junction ensures stable leakage (<1000 µA at 5.0 V) and fast response (<1 ns), while low incremental surge resistance enables effective energy diversion during ESD or load-switching transients.
The SMB10J5.0AHE3/52 is rated for 150 °C maximum junction temperature 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 it is halogen-free RoHS-compliant with AEC-Q101 qualification for automotive-grade reliability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 5.0 V - Maximum continuous reverse operating voltage before significant leakage begins; matches standard 5 V logic and supply rails. |
| VBR (min/max) | 6.40 V / 7.07 V - Breakdown occurs within this range at 10 mA test current; defines reliable turn-on threshold under surge conditions. |
| VC @ IPPM | 9.2 V - Clamping voltage at 108.7 A peak pulse current; limits downstream IC stress during worst-case transients. |
| PPPM | 1000 W - Peak pulse power handling (10/1000 µs waveform); supports high-energy automotive and industrial surges. |
| IPPM | 108.7 A - Maximum non-repetitive surge current capability; determines survivability against ISO 7637-2 Pulse 1/2a/5a events. |
| TJ max | 150 °C - Maximum junction temperature rating; enables operation in under-hood automotive environments. |
| AEC-Q101 | Qualified - Validated for automotive applications including engine control units, body electronics, and ADAS sensor interfaces. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ5.0A-E3/52 | Same SMB package, 600 W PPPM, 64.9 A IPPM, 9.2 V VC; lower surge capacity. | Targeted at consumer-grade or non-automotive industrial use; lacks AEC-Q101 qualification. | Select when cost sensitivity outweighs automotive reliability requirements and surge energy is ≤600 W. |
| 1.5SMC5.0A | Higher-power SMC package (1500 W), same VWM/VC, but larger footprint (7.11 mm × 6.22 mm) and no AEC-Q101 rating. | Used where PCB space allows larger package and higher surge margin is needed, e.g., telecom power supplies. | Choose only if board layout permits SMC footprint and AEC-Q101 is not required. |
Compared with SMBJ5.0A-E3/52 and 1.5SMC5.0A, the SMB10J5.0AHE3/52 uniquely combines AEC-Q101 qualification, 1000 W surge rating, and SMB footprint-enabling automotive-grade protection without layout redesign or derating compromises.

FAQ
What is the clamping voltage of SMB10J5.0AHE3/52 at its rated peak pulse current?
The SMB10J5.0AHE3/52 has a maximum clamping voltage (VC) of 9.2 V at its peak pulse current (IPPM) of 108.7 A, measured under the standard 10/1000 µs waveform. This value ensures protected circuits remain below critical overvoltage thresholds during high-energy transients, and is confirmed in the Vishay datasheet Document Number 88422, page 2.
Is SMB10J5.0AHE3/52 qualified for automotive applications?
Yes, SMB10J5.0AHE3/52 is AEC-Q101 qualified, as indicated by the "HE3" suffix in its part number and explicitly stated in the Vishay datasheet revision 09-Jan-2024. This qualification covers stress tests including temperature cycling, high-temperature operating life, and ESD, making SMB10J5.0AHE3/52 suitable for under-hood and cabin automotive modules.
What is the standoff voltage (VWM) and why is it important for SMB10J5.0AHE3/52?
The standoff voltage (VWM) of SMB10J5.0AHE3/52 is 5.0 V - the maximum DC or continuous reverse voltage the device can withstand without entering avalanche breakdown. This matches standard 5 V logic and supply rails, ensuring minimal leakage (<1000 µA) during normal operation while enabling precise overvoltage triggering during transients.
Does SMB10J5.0AHE3/52 have a defined polarity, and how is it marked?
Yes, SMB10J5.0AHE3/52 is a unidirectional TVS diode with defined polarity: the cathode is marked by a visible color band on one end of the SMB (DO-214AA) package. The anode is the unmarked end. Correct orientation is essential - cathode connects to the protected line (e.g., 5 V rail), anode to ground - to ensure proper reverse-bias clamping behavior.
What packaging and moisture sensitivity level does SMB10J5.0AHE3/52 use?
SMB10J5.0AHE3/52 is supplied in 7" plastic tape-and-reel format (package code "52"), with 750 units per reel. It meets MSL Level 1 per J-STD-020, meaning it has no floor life limitation and can be subjected to standard lead-free reflow profiles up to 260 °C peak without baking - simplifying SMT manufacturing for SMB10J5.0AHE3/52.
